Ethylene Oxide Covid Test Sterile Swab

Posted on 2022年3月17日2022年3月30日 by Dr. Lee

EO sterilization refers to ethylene oxide sterilization.

Ethylene oxide (EO) is a highly efficient and broad-spectrum gaseous disinfectant.

It is by far the only most reliable and widely used sterilization method recognized worldwide.

The nasal sampling flocked swabs included in the COVID-19 test kits are sterilized by EO or gamma-ray sterilization.

Rest assured, the swab is safe to use. Including ethane is a gas use commonly used to sterilize different types of medical equipment, flocked swabs for test kits.

The time period for the entire process includes multiple heights and set-up phases, including post-swab removal of sterilized equipment to control ethane treatment.

Allows monitoring of residues in contact with humans (EO amount has been according to ISO 10939-7:2008) ).

Ethylene Oxide Covid Test Sterile flocked Swab Principle

What is the principle of ethylene oxide sterilization (EO sterilization)?

Ethylene oxide, also known as ethylene oxide, has the molecular formula C2H4O.

The boiling point is 10.4°C, it is soluble in water, and the explosion limit in air is 3% to 100% (volume).

Ethylene oxide is a highly volatile, explosive, flammable and toxic substance with ether smell when volatilized. It is a spectral sterilant.

Ethylene oxide can effectively kill various microorganisms, including bacterial propagules, spores, viruses and fungal spores, and is a broad-spectrum high-efficiency sterilant.

Ethylene oxide molecule can produce alkylation reaction with a carboxyl group, amino group, sulfhydryl hydrogen group and hydrogen group on gene proteins necessary for metabolism in bacterial cells.

Instead of the unstable hydrogen atoms on the above groups, form a hydroxyethyl group.

The rooting compound, because this compound destroys the necessary reactive groups in the important metabolic reactions of microorganisms, affects the action of bacterial enzymes, and causes the death of microorganisms.

Nasal swabs included in COVID-19 inspections are EO sterilized.

I heard that ethylene oxide sterilant is toxic and carcinogenic, but covid sterile swaps are all sterilized with ethylene oxide.

Is it safe for us to use a covid swab?

Is the risk of cancer caused by directly entering the respiratory tract greater?

The words “Clean and Sterile EO” on the product packaging of sterile flocked swabs. At this point there’s a crowd that’s saying “

Specimen Collection Swab Ethylene Oxide In Swabs

It’s completely dry here.

There’s no result. But once you put it in a person’s nose, it’s wet. Once you inhale it, it’s going to kill us. It’s really killing people.”

While it’s safe to say that direct exposure to ethylene oxide is actually linked to cancer (here), that doesn’t suggest that swabs sterilized with ethylene oxide definitely cause cancer cells.

Ethylene oxide is a valuable disinfecting gas because it is very good at inactivating bacteria.

It is used in factories in a very tightly controlled method to ensure that people working in manufacturing plants are not put at risk.

It is a common chemical used to sterilize clinical tools and leave a minimal amount of product behind.

In conclusion, EO is a gas commonly used to sterilize clinical equipment such as COVID-19 nasal swab tests.

Ethylene oxide (ethylene oxide) is a highly efficient and broad-spectrum gaseous disinfectant.

It is by far the only most reliable and widely used sterilization method recognized worldwide.

Although EO is carcinogenic, the use of this gas is safely regulated and has actually been used for decades.

Sterilization procedures are regulated to ensure minimal EO residues on medical tools.

What is Viral Transport Media

Posted on 2022年3月14日2022年3月30日 by Dr. Lee

What is VTM?

VTM is the acronym for Viral Transport Media, which contains nutrients that carry the virus and keep it active so that the sample can reach the laboratory for testing.

VTM virus preservation solution is suitable for the collection, preservation and transportation of common virus samples.

Such as new coronavirus, influenza virus, hand, foot and mouth virus. It can collect throat swabs, nasal swabs or tissue samples from specific parts.

And the stored samples can be used for subsequent nucleic acid extraction or Purification and other clinical experiments.

Virus Transport Medium (VTM) Definition

The virus transport medium sampling tube is a complete set of centrifuge tubes for sampling and transporting viruses.

What is Viral Transport Media

Such as new coronavirus, influenza virus, hand, foot and mouth virus in the microbial sampling transport tube.

Also known as the specimen transport tube. commoditized products.

A nutrient is used to carry and maintain the viability of test specimens (viruses) for the identification and further processing of samples in laboratories.

Viral Transmission Media Principles (VTM)

Since there is no cellular structure. Viruses cannot replicate themselves, but instead, invade genes into host cells and replicate new viruses with the help of the latter’s replication system.

After the virus sample is collected, in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample, the sampling swab will be put into the transportation medium for storage and transportation.

Transportation medium composition and inspection principle:

1. The combination of various antibiotics has broad-spectrum antibacterial and antifungal effects.

2. As a protein stabilizer, bovine serum albumin (BSA) can form a protective film on the protein shell of the virus, making it difficult to decompose and ensuring the integrity of the virus

3. The neutral environment constructed by Hank’s buffer helps to increase the survival time and infection stability of the virus.

4. Phenol red is an acid-base indicator, the discoloration area is 6.6 (yellow)-8.0 (red), and it is red at 7.2-7.4.

Vtm Kit

The most stable pH value of the viral outer layer protein is 7.2-7.4, which is also the pH value range of Hank’s buffer. If contaminating molds or bacteria are not inhibited by antibiotics, they can multiply, releasing carbon dioxide and lowering the pH.

At this time, the appearance of the sampling solution will change from red to yellow.

Notes:

To produce an isotonic solution containing proteins to protect viral structures, antibiotics to control microbial contamination, and one or more buffers to control pH.
Use the concept of assays such as nucleic acid amplification assays (NaAt) to prepare viral delivery media while preventing samples such as drying.

Composition of viral transport media (VTM Kits)

There are mainly the following parts:

1. Sampling swab with disposable sterile plastic rod/rayon head;

2. Sterile sampling tube containing 3ml of virus maintenance solution;

In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc.

Viral delivery media typically have protective protein components, antimicrobial agents to prevent the potential for contamination, and buffers to maintain the pH of the solution.

Some VTMs also have additional ions and minerals that help keep such samples viable.

How to use Virus Transfer Media?

Liquid transfer media are primarily used to transfer the swab or material from the collection swab into the media.

It facilitates the collection and transport of samples in areas where it is not available.

Precautions for use:

1. Before sampling, indicate the sample information on the label of the cryopreservation tube;

2. According to different experimental purposes, use sampling swabs to sample at the corresponding parts (the most commonly used are nasopharyngeal swabs, pharyngeal swabs are the oral swabs in the product);

3. Immediately after sampling, put the swab into the sampling tube containing the virus transport medium, break it at the breaking point, and tighten the tube cover;

4. The specific sampling methods are as follows:

a) Nasal swab: Gently insert the flocked swab head into the nasal palate, stay for a while and then slowly turn to exit. Swab the other nostril with another swab, immerse the swab head in the sampling solution, break it at the breaking point, and discard it.

b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a flocked swab, and also immerse the swab head in the sampling solution and discard it.

What is Swab Test

Posted on 2022年3月8日2022年3月22日 by Dr. Lee

If you are considering whether you should get a COVID-19 swab test, symptomatic or asymptomatic.

Under normal circumstances, the virus is spread through the air to our nose or mouth.

We have to wear masks to prevent the infection of the virus from the source.

Assuming we are unfortunate enough to carry the new crown, the virus will enter the throat through the nose and mouth, and then enter the alveoli through the trachea and bronchi.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs. The sample is collected from your nasal cavity or mouth when the nurse’s sister gives you a nucleic acid test.

At this time, we will use nasopharyngeal swabs and oropharyngeal swabs, which are the samples taken by the nurse sister from your nasal cavity or oral cavity when you are doing nucleic acid testing.

Due to the convenient operation and high accuracy, these two methods have been widely used. Now I will tell you about nasopharyngeal swabs and oropharyngeal swabs in detail.

What is a nasal swab test?

Specimen Collection Swab

Our respiratory tract is divided into the upper respiratory tract and lower respiratory tract. The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs. In medicine, the cricoid cartilage is used as the boundary to distinguish.

The nasopharyngeal swab test is a medical test method. A medical cotton swab is used to wipe a little secretion from the nasopharynx of the human body, placing it in a special incubator, and placing it in a temperature-controlled device for cultivation. Can understand the patient’s condition, oral mucosa and pharyngeal infection.

Compared with oropharyngeal swabs, nasopharyngeal swab sampling has the following advantages:

1. When collecting oropharyngeal swab samples, the sampler can see the location of the pharynx to be sampled, and the irritation to the oropharyngeal mucosa may cause the sampled to cough, nausea, and even vomit.

2. When collecting nasopharyngeal flocked swab samples, the irritation to the nasopharyngeal mucosa is relatively small if the operation is standardized.

3. But the sampler cannot see the location of the pharynx for sampling, and mainly relies on the resistance felt by the hand to complete the sampling, so the technical requirements are higher, and the tools used are also more complicated.

4. It can stay in the pharynx for a longer time to obtain a sufficient amount of specimens, which is why the positive rate of the swabs reported in the literature is higher than that of oropharyngeal swabs.

5. The patient’s tolerance is good. After the skilled operation, sampling can be performed without anesthesia, but surface anesthesia and contraction of the nasal mucosa can be performed first for beginners.

COVID Swab test : How can I do a Swab Test

Posted on 2022年2月17日2022年3月22日 by Dr. Lee

From last year to now, the epidemic has changed our way of life. Working from home, quarantine, temporary unemployment, children taking early leave or schooling at home, and less seeing family, friends, and colleagues, many changes require us to adapt.

Since late December 2021, the epidemic in Hong Kong has worsened sharply after the Chinese New Year. On February 5, Hong Kong recorded 300 new positive test cases every day, setting an epidemic record; two days later, the number rose to 607; it exceeded 1,000 for the first time on February 9, and exceeded 2,000 on the 14th.

In the face of the pneumonia epidemic of new coronavirus infection, how should we conduct swab tests? How can we do personal protection in our daily life?

The new coronavirus is transmitted through the respiratory tract, and the pharynx is the place where such viruses gather more. Throat swab samples are medical cotton swabs, which are dipped in a small number of secretions from the pharynx of the human body, and the samples taken are throat swab samples. the virus type.

How can I do a swab test?

Cell medical (Dongguan) Co., Ltd., a professional VTM kits and swabs manufacturer, disposable swab tubes exporter, has many years of experience in medical application molding and flocking treatment heads and swabs.

When performing a swab test, we make the following recommendations to the sampler:

Residents are encouraged to blow their noses to clear their nasal passages.
If residents cannot perform this task, wipe their nostrils with a flocked swab or tissue.
The Resident’s name, date of birth and time of collection are affixed to the vial.
hand hygiene. Wear a mask, goggles and gloves.
With the head in a neutral position, insert the dry swab from the nostril straight back (not upward) along the base of the nasal passage until it reaches the posterior wall of the nasopharynx—usually halfway from the corner of the nose to the front of the ear (about 4~4~ 6 cm or 1.6-2.5 inches).
Gently swirl the flocked sampling swab and let it sit for a few seconds.
Carefully remove the flocked swab without touching the sides of the nostrils.
Open the virus sampling tube (VTM Tube) and place the swab in the transport medium.
Break the flocked swab along with the swab Breakpoint and close the cap.
Place the sample (viral sampling tube) in the inner bag of the plastic biohazard bag.
Remove gloves for hand hygiene; remove masks for mouth hygiene.
Complete the application form and place it in the small outer bag of the plastic biohazard bag.
Place the entire plastic biohazard bag in a separate clean paper or ziplock bag.
Refrigerated specimens.
shipped to the laboratory.

How can we do personal protection in our daily life?

1. Wash your hands frequently and maintain good respiratory hygiene.

Wash your hands under running water with soap or hand sanitiser.
Practice good respiratory hygiene. Cover your mouth and nose with a tissue or towel when coughing or sneezing, wash your hands after coughing or sneezing, and avoid touching your eyes, nose or mouth with your hands.

2. Enhance physical fitness and immunity, keep the environment clean and ventilated.

Enhance physical fitness and immunity, eat a balanced diet, exercise moderately, work and rest regularly, and avoid excessive fatigue.
Open windows for ventilation no less than 3 times a day, 20 to 30 minutes each time.

3. Minimize activities in crowded places and pay attention to symptoms.

Minimize activities in crowded places and avoid contact with patients with respiratory infections.
If you have respiratory symptoms such as cough, runny nose, and fever, you should isolate and rest at home, and seek medical attention as soon as possible if the fever persists or the symptoms worsen.

4. The role of handwashing in preventing respiratory tract-borne diseases.

Proper handwashing is one of the most effective measures to prevent diarrhea and respiratory infections. The Chinese Center for Disease Control and Prevention, the World Health Organization, and other authorities recommend washing hands with soap and water (water).

5. What should I do if there is no clean water outside the trip and it is inconvenient to wash hands?

You can clean your hands with alcohol-based sanitisers. Coronaviruses are not acid and alkali resistant and are sensitive to organic solvents and disinfectants. 75% alcohol can inactivate viruses, so a certain concentration of alcohol disinfection products can be used as an alternative to soap and running water for handwashing.

Do a good job of COVID-19 nucleic acid swab testing, maintain a healthy lifestyle, and do personal hygiene. During the epidemic, follow the principles of going out less, wearing masks, washing hands frequently, actively isolating, and maintaining personal and home hygiene.

Does the Nasal Swab Hurt?

Posted on 2022年2月14日2022年3月22日 by Dr. Lee

“Two and a half hours ago, I had a covid test, twice in one nostril, and my nose still hurts and feels weird.”

Brain Scraper: Does the Nasal Swab Hurt?

Nasal swab and throat swab which is painful? Nucleic acid testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

Does nasal swab test hurt?

A nurse is doing a swab test on a patient

The nasopharyngeal swab test does not produce painful symptoms, and some patients experience discomfort. This inspection is to use a medical flocked swab to enter the nasopharynx to take a small number of secretions and send them for inspection. The pathogenic bacteria can be isolated through bacterial culture. During the operation, the patient will experience mild nausea and discomfort, which is generally within the tolerable range. During the operation, the medical staff is gentle and skilled, so there will be no pain.

Activates unconscious, instinctive reflexes. Depending on the intensity of the body’s response, discomfort, tearing, pain, and other reactions can result. Some people gag, cough, sneeze – it’s all part of the same reflex. For people who are more prone to headaches, this can cause intense discomfort.

Swab testing generally takes nasal swabs and throat swabs, and the sampling methods of these two are also different.

A nasal swab refers to a swab deep from the nasal cavity, all the way to the nasopharynx, and the secretion is taken for smearing.

Throat swabs are taken directly from the posterior pharyngeal wall of the oral cavity and the tonsillar fossa by opening the mouth. Nasal swabs are generally slightly more painful than throat swabs because they need to be passed through the nasal cavity. If there are structural abnormalities in the nasal cavity, such as a deviated nasal septum or hypertrophy of the turbinate, or there is hyperplasia in the nasal cavity, such as nasal polyps or the operator does not know much about the anatomical structure of the nose, it is possible that a cotton swab may not easily reach the nasopharynx through the nasal cavity. Partial or damaged nasal mucosa, causing local bleeding or pain and other discomforts.

Precautions before nasal swab testing?

1. Try to avoid eating 2 hours before the nucleic acid test to avoid vomiting;

2. During the inspection, reduce swallowing and do not do throat clearing (such as expectoration and spitting).

3. Pay attention to maintaining a distance of more than 1 meter between people and minimize conversations;

4. Do not drink beverages (including water), smoke, drink, chew gum, etc. 30 minutes before sampling;

5. The tested person should be informed Whether the collection personnel have a relevant past medical history (such as the history of nasal surgery, deviated nasal septum, blood disease, throat disease, etc.);

The person who did a few nasal swabs tells you how to do it without pain.

I’ve done nasal swabs several times and it’s been painless every time. Much more comfortable than a throat swab. I see a lot of netizens saying that the nasal swab is very painful and sour, this is because your posture is not correct! !!

Looking at this schematic diagram, in fact, no matter the nasal swab or the throat swab, their purpose is to let the cotton swab sample from the inner wall of the throat. Nasal swabs are not meant to poke your heavenly lid!

Therefore, you should tilt your head as far back as possible to allow the flocked swab to go in horizontally. That way the only thing you feel is a little bit of cold, and it’s over in less than 5 seconds. But if you keep your head upright, the cotton swab can only be stabbed from the bottom to the top, which will definitely stab the upper part of the nasal cavity. That position is very sensitive, and it hurts when stabbed. And because the doctor can’t see the location, he can only stir in it by the feel of the hand, so you will be sour to tears.

Nylon Flocked Swabs

Posted on 2022年2月9日2022年3月22日 by Dr. Lee

During an outbreak, everyone should be familiar with sampling swabs. When doing nucleic acid, touching the nose and throat is directly touching the sampling site of human organs, that is, directly touching our human organs. Therefore, the material of the sampling head will affect our comfort and is closely related to the subsequent detection.

On This Page

What is a Nylon flocked swab?

About sampling swab material.

What are the types of swab tests?

Nylon flock swab

Sampling swabs should be polyester, nylon and other non-cotton, non-calcium alginate swabs, and the handle should be non-wood. The breakpoint is located about 3cm from the top of the swab head, which is easy to break.

NASAL FLOCKED SWAB

Moreover, the experimental analysis shows that the extraction efficiency of nylon flocked swabs is the highest. In contrast, the recovery efficiency of nylon flocking swabs is also higher than that of other material swabs.

Nylon fibre flocking technology. The front end is coated with vertically fixed nylon short fibers, so that the entire sampling area of the sampling swab has no absorption holes, and the sampling sample will not be scattered in the fibers, which is conducive to faster and more efficient sampling!

Compared with traditional winding swabs, nylon flocking swabs collect and release 3 times the number of samples, do not damage cell samples, ensure the survival rate of cell samples, do not leave fatty acids, do not affect the test and detection results, not to mention Said to cause harm to the human body.

What materials cannot be used for sampling swabs?

As we all know, the materials of medical swabs have always attracted much attention. After all, medical swabs come into direct contact with the skin. People who touch the skin can first touch alcohol for disinfection, that’s fine, but what about those who have direct contact with organs? For example, the throat swab we are most familiar with during the epidemic.

The throat swab is in direct contact with the sampling site, and the material of the sampling head is closely related to subsequent testing. The sampling swab head should be made of nylon flocked swabs or rayon, and calcium alginate sponges or wooden stick swabs (including bamboo sticks) should not be used.

Cotton products should not be used for the swab head, because the cotton fiber has strong adsorption to protein and is not easy to clean into the subsequent storage solution; wooden.

What are the types of swab tests?

There are two different types of COVID tests – Swab tests and antibody tests.

1. Swab tests can show if you have an active coronavirus infection and should take steps to isolate or isolate yourself from others. There are currently two types of diagnostic tests – molecular (RT-PCR) tests that detect the genetic material of the virus, and antigenic tests that detect specific proteins on the surface of the virus. Samples are usually collected with a nasal or throat swab, or saliva spits into a test tube.

2. Antibody tests look for antibodies that the immune system produces in response to a threat, such as a specific virus. Antibodies can help fight infection. Antibodies can take days or weeks to develop after infection and may remain in the blood for several weeks after recovery.

Therefore, antibody tests should not be used to diagnose active coronavirus infection.

Right now, researchers don’t know whether the presence of antibodies means you’ll be immune to the coronavirus in the future. While there is a lot of uncertainty surrounding this new virus, the widespread availability of antibody testing and clinical follow-up over time also has the potential to provide the medical community with more information about whether and how long a person has recovered from the virus of people have a reduced risk of infection if they are re-exposed to the virus. Learn more about antibody testing.

The Mission of A Virus Test Swab

Posted on 2022年1月25日2022年3月22日 by Dr. Lee

The Mission of A Virus Test Swab

From the sampling point to the testing room, then to the temporary storage point of medical waste.

Then to the hazardous waste centre, to the power plant, and finally to the soil.

A swab for nucleic acid detection completed the task and became a piece of pollution-free ash and fill it in the soil.

At present, we are in a critical period of anti-epidemic.

An ordinary hospital has a maximum of 11,220 samples per day at a single sampling point.

The Mission of A Virus Test Swab

At nine o’clock in the morning, at the nucleic acid testing and sampling service point, citizens who were ready to test lined up.

Everyone wears a mask and consciously separates one meter from each other.

At the beginning of the inspection window, the heavily armed nurses washed their hands with an antiseptic solution.

And then removed a flocked swab about 15 cm long from the packaging bag to take a sample before taking the throat swab.

The nurse opened the collector’s mouth wide, and she skillfully inserted the flocked swab into her pharynx.

Then picked up a sampling tube (virus transport medium) with her left hand. And inserted the collection stick into the sampling tube with her right.

With a little force, the tip of the cotton swab breaks enters the sampling tube, seals it. And throws the long stick into the yellow medical waste bin.

As a testing point for ordinary citizens and inpatients, as an ordinary citizen and inpatients, the use of cotton swabs in an ordinary hospital reached 11,220.

Medical waste treatment forms closed-loop management in nucleic acid testing laboratories.

Take the flocked swab, put the swab head into the sampling tube, and paste a barcode similar to “ID card”. And carefully seal it, put it into a transparent sealed box.

And then send it to the transfer cabin of the PCR laboratory of the Department of Infectious Diseases by staff wearing protective clothing.

The PCR laboratory is under negative pressure, and after the virus enters, it cannot come out. After the outbreak, the PCR laboratory strictly abides by the medical waste treatment process, forming closed-loop management of the laboratory.

An hour later, staff in protective suits transported medical waste out of the ward in sealed yellow bags and sealed with “extremely infectious waste”.

Then, the workers send these medical wastes by trolleys to the medical waste temporary storage area at the nucleic acid collection point 100 meters away. For the medical wastes for nucleic acid testing, he transports an average of about 35 kilograms per day.

We need to place the virus sampling tube for 48 hours during the transfer process

Except for professionals, our PCR laboratory does not allow patients and the public to enter here.

To ensure safety, all medical waste from nucleic acid testing collection points, including swab sticks, is kept here for 48 hours.

After our test results come out and are confirmed to be correct, they will be sent to the hazardous waste treatment centre by a medical waste transfer vehicle.

At ten o’clock in the morning, the staff of the hazardous waste centre arrived at the scene. Unload the empty shipping box and load the ship with medical waste that has been sitting for 48 hours.

The sampling flocked swabs used must be incinerated at high temperatures above 1100°C.

There are two buildings, an incineration workshop and a cooking room, in the yard of the Hazardous Waste Center.

The staff in protective suits skillfully unload boxes of medical waste from the transfer vehicle and load boxes of hazardous waste into bucket elevators.

EO sterilization refers to ethylene oxide sterilization.

Ethylene Oxide Covid Test Sterile flocked Swab Principle

What is the principle of ethylene oxide sterilization (EO sterilization)?

Nasal swabs included in COVID-19 inspections are EO sterilized.

Is it safe for us to use a covid swab?

In conclusion, EO is a gas commonly used to sterilize clinical equipment such as COVID-19 nasal swab tests.

Ethylene oxide (ethylene oxide) is a highly efficient and broad-spectrum gaseous disinfectant.

It is by far the only most reliable and widely used sterilization method recognized worldwide.

Although EO is carcinogenic, the use of this gas is safely regulated and has actually been used for decades.

Sterilization procedures are regulated to ensure minimal EO residues on medical tools.
