Flocked swabs for sample collection
The flocked swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod.
The brush head can be used for Virus cell collection.
It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

Why flocked swabs?
The flocking swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod. The brush head can be used for DNA collection. It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.
So that there is no absorption hole in the sampling area of the whole sampling swab.
And the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.
Traditional cotton swabs can not completely collect and elute samples, while flocking swabs can elute 95% of samples.
Therefore, the use of flocking swabs has great advantages for various sample collection applications.
Nasopharyngeal flocked swab;
Flocked swabs have some advantages;
1. Sampling is comfortable and easy to use;
Flocking swabs now basically use “spray technology”, which vertically attaches millions of nylon fibers to the head of medical ABS swab rod through the flocking process of electrostatic charge.
The function of the vertical nylon fiber is similar to that of a soft brush. The use of this soft brush in the sampling process makes the user feel free of foreign objects. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.
For example, the nose swab is thinner and softer at the upper end of the rod, and the breaking point is longer, which fully conforms to ergonomics.
2. Flocked swab samples release more;
The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample is kept on the surface to make elution easier. It is much larger than the traditional winding cotton swab. The experimental research shows that the collection and release of flocking swab can reach 95% of the sample, while the cotton swab is only about 20%.
Because most of the samples collected by the cotton swab are easy to be intercepted in the fiber matrix layer of the head during release, it is not easy to release or release a small amount.
3. Flocking swab has biocompatibility and is an ideal choice for PCR;
In order to limit the damage to the sample and improve the accuracy of detection, while the flocking swab is PCR compatible and does not contain RNase and DNase.
Operation method of flocked nylon swab:
Take the sampling method of oropharyngeal swab as an example;
1. First, ask the patient to sit down, then let the patient tilt his head back, open his mouth, and make an “ah ~” sound.
2. The sampler fixed the patient’s tongue with a tongue depressor, and used a flocking swab to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.
3. Wipe repeatedly for 3 ~ 5 times to collect mucosal cells.
4. Slowly take the swab out of the mouth, vertically put it into the virus preservation solution, break the tail of the swab, and tighten the sampling tube to avoid leakage.
5. Send to the laboratory for testing as soon as possible.
Swab flocked matters needing attention:
1. The swab shall be placed vertically in the sampling tube, and shall not be wiped to the bottle mouth to avoid pollution.Viral Transport Medium.flocked swab copan.
2. It is best to send it or send it to the laboratory for inspection on the day of sampling.
3. Before submission for examination, it must be verified that the specimen is consistent with the submission form. The appearance of the sampling tube must clearly write the patient’s name and basic information.
4. The submitted samples must submit (or submit the electronic version in advance) screening information form, inspection form and other materials.
