What to use a flocking sampling swab?

Maybe you have such a question in your mind, why use flocking sampling swabs? After reading this article, you may know the answer

Reasons for using flocking swabs:

In our traditional fiber swabs, the sample is not only intercepted by the fiber mass gap, which makes the sample permeate, dilute and intercept in the fiber, but also slows down the collection and release speed.

Nylon flocking swab not only has good sample collection and release capacity, but also has a release rate of more than 80%.

Generally speaking, the sampling time of flocking swabs is 3-5 seconds, while that of cotton swabs is 15-120 seconds, or even longer. This in the diagnosis process, caused serious pressure on the staff. Only faster sample extraction can complete the collection and analysis more efficiently.

The characteristics of huachenyang flocking swabs were as follows

(1) The swab was make by spraying dense nylon fiber technology.

(2) According to the analysis items, there are soft or brush like swabs, which have reach the maximum collection amount.

(3) Disposable sterile injection swab with break point.

(4) Flocking swab technology can improve the adsorption / release amount of samples and improve the sensitivity of analysis

(5) No sample rejection indicates that the specimen can be delivere faster and less.

(the upright nylon fiber is like a soft brush, which can not only collect more cell samples.

Moreover, the capillary effect between nylon fibers enhances the bearing capacity of water-based samples.

Moreover, the samples are concentrate on the surface of the swab, which is easier to elute.

More samples can be adsorbe by nylon swabs.)

Methods: virus swab specimens were collected

Methods: virus swab specimens were collecte

We all know that the collection method of virus swab specimen is basically to use the swab to sample the infecte place or part of the virus, and then put it into the virus sampling tube containing preservation solution without touching other places, so as to conduct virus detection later. So basically, the soup is change without changing the dressing.

For example, throat swabs and nasal swabs were use to detect new coronavirus

Methods: throat swabs were collected

Inform the patient of the purpose of examination, collection method and collection time. It is best to collect specimens before using antibiotics.

Objective:

To study the clinical effect of the method

Secretions were collecte from pharynx or tonsil for bacterial culture or virus isolation to assist in clinical diagnosis and treatment.

Prepare sampling supplies:

Disposable sampling swab, virus sampling tube, tongue depressor and biological bag

Operation method:

(1) Ask the patient to sit down, tilt his head back, open his mouth and make a “ah ~” sound

(2) The patient’s tongue was fix with a tongue depressor, and a disposable swab was used to cross the tongue base to the posterior pharyngeal wall, tonsil recess and lateral wall;

(3) Repeatedly wipe 3-5 times to collect mucous membrane cells or sputum

(4) . gently remove the swab to avoid touching the tongue, the suspension, the oral mucosa and saliva

(5) Put the swab into the virus sampling tube gently and vertically. Break off the tail of the swab, and leave the tail of the swab so that it is completely place in the tube. Be careful that the swab does not touch the wall of the tube.

(6) . tighten the cap, mark it, and seal it in the biosafety bag.

(7) It should be sent to the laboratory for testing in time. If it can not be sent for inspection in time, it should be store at low temperature.

Methods: nasal swabs were collecte

(1) Ask the patient to sit down with his head slightly back and remove the secretion from the front nostril first;

(2) . measure the distance from nostril to ear base with swab and mark with finger

(3) . gently insert the swab into the nostril until it is marke or stopp when there is obstruction. Let the swab stay in the nose for 15-30 seconds, and then rotate it gently three times.

(4) . slowly pull out the nasal swab and quickly put it into the virus sampling tube. Then break the swab, leave its tail and place it completely in the tube.

(5) . tighten the cap, mark it, and seal it in the biosafety bag.

(6) If it is necessary to collect from two nostrils, one swab should be used.

(7) It should be sent to the laboratory for testing in time. If it can not be sent for inspection in time, it should be store at low temperature.

What are the requirements for sampling swabs

What are the requirements for sampling swabs

Since the outbreak of the epidemic,

The virus sampling tube and nucleic acid test throat swab have been pushed to the cusp of the storm.

Many people worry that irregular sampling swabs will cause false positives or false negatives.

Because this will not only threaten personal safety but also cause great harm to society, the result will be very serious.

so the National Health Commission issue the “New Coronary Pneumonia Laboratory Testing Technical Guidelines (Third Edition)” in the specification requirements: (The original text is quote here)

China’s requirements for sampling swabs:

Pharyngeal swab: Use two plastic rod swabs with polypropylene fiber heads to wipe both pharyngeal tonsils and posterior pharyngeal wall at the same time,

and immerse the swab head in 3mL virus preservation solution (isotonic saline solution, tissue culture solution or Phosphate buffer solution),

discard the tail, and screw the cap tightly.

Have you see that the clear material requirements for swabs in my country’s guidelines require polypropylene fiber,

but the manufacturer that produces swabs needs to pay attention to not using wooden stick swabs and calcium alginate swabs.

Why What? Please look down

U.S. requirements for sampling swabs:

Let’s take a look at the requirements for sampling swabs use in the collection of nasal and pharynx samples in “InterimGuidelines for Collecting,

Handling, and Testing Clinical Specimens from Patients Under Investment (PUIs) for 2019NovelCoronavirus (2019-nCoV)” issued by the United States CDC.

The original text is: Use only synthetic fiber swabs with plastic shafts .

Do not use calcium alginate swabs or swabs with woodeen shafts,

as they may contain substance that inactivate some viruses and inhibit PCR testing.

Place swabs immediately into sterile tubes

The translation is: only synthetic fiber swabs with plastic rods can be use.

Calcium alginate swabs or wooden stick swabs cannot be used,

because they may contain substances that inactivate certain viruses and inhibit PCR detection.

to sum up:

We all know that the United States CDC has high requirements for the materials of medical devices,

and this time is no exception, and it explains why wooden stick swabs and calcium alginate swabs cannot be used.

China also has clear regulations on sampling swabs, so manufacturers must not be sloppy in this regard.

Nasopharyngeal swab

Nasopharyngeal swab

What is a nasopharyngeal swab?

Nasopharyngeal swabs are actually relatively long sampling swabs.

Not only are relatively long disinfection sampling swabs, but their main function is to use nasopharyngeal secretions for bacterial culture and drug sensitivity testing.. Through bacterial culture and drug sensitivity test, the source of infection in the nasopharynx and the microbes in the nasopharynx can be selected,

and then a drug sensitivity test can be done to determine which drugs are sensitive,

so that sensitive drugs can be selected for treatment, so as to achieve better results Effectiveness,

so the nasopharyngeal swab is actually a sampling swab for taking tissue samples.

Nasopharyngeal swab specimen collection

Nasal swab collection method

purpose

Normal people’s pharyngeal isthmus culture should have normal oral flora without the growth of pathogenic bacteria. The bacteria in the pharynx all come from the outside world and do not cause disease under normal circumstances, but infections can occur under the body’s systemic or local resistance and other external factors to cause diseases. Therefore, pharyngeal swab bacterial culture can isolate pathogenic bacteria, which is helpful for the diagnosis of diphtheria, suppurative tonsillitis, and acute pharyngitis.

Nasal swab collection method

①. Ask the patient to keep his head still and remove the secretions on the surface of the anterior nasal cavity. The collector can stand on the side of the collector, reducing occupational exposure caused by coughing and sneezing, and alleviating the pressure on the collector.

②. Measure the distance from the nostril to the root of the ear with a swab and mark with your hand.

③. Gently insert the swab into the nostril in the direction perpendicular to the nose (face) through the nasal cavity, with a feeling of touching the wall until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then gently rotate it 3 times.

④. Put the swab into the virus transport medium, not only to break the swab stick, but also to put it completely into the test tube.

⑤. Tighten the cap of the tube, mark it, put it in a plastic bag and seal it.

⑥. Submit the specimens for inspection in time

Now that the epidemic is under control, do you need a throat swab?

swab

preface

Now it is October of 2020. As we all know, this year is not a peaceful year. Because of the outbreak of the epidemic, we have brought a lot of inconvenience to our life and work.

Fortunately, the epidemic situation has been controlled in China. Do we still need the throat swabs that were used most frequently before?

The function of throat swab

First of all, what is the function of throat swab? Used the throat swab examination is mainly to check the throat of diphtheria,

acute suppurative tonsillitis, acute pharyngitis and other important examination methods of pharyngeal diseases.

The specific operation is to press the tongue of the patient with a tongue depressor, take a little throat secretion with a clean swab, and examine it under a microscope.

These secretions can also be used for drug sensitivity test to find harmful bacteria colonized in the throat, providing clinical help for the next step of diagnosis and medication guidance.

Pharyngeal swab examination will have certain discomfort reaction, some patients in the throat swab examination will have mild pharyngeal reflex, but it can be tolerated,

so throat swab examination is very necessary. What’s more, what throat swabs do during the epidemic is to take secretions to check for new coronavirus.

How to use throat swab

And now it is autumn and winter season, the climate is relatively dry,

there are more children in this season is very easy to appear throat inflammation,

swallowing food throat pain, because of throat inflammation or bronchitis caused by aphasia, nasopharyngitis and a series of symptoms of pharyngitis,

causing pharyngitis pathogenic microorganisms, mainly viruses, occasionally also bacteria. The throat swab test can quickly detect whether the pathogen causing the infection is bacteria or virus. How does this test operate? Let’s take a look at it

How to use throat swab:

① With the help of tongue depressor, the subjects opened their mouth and made a “ah” sound. The palate was lifted up to expose the posterior pharyngeal wall. The swab crossed the root of the tongue and reached the pharyngeal stenosis. Quickly wipe the palatal arch, pharyngeal and tonsillar secretions on both sides.

② Put the swab into the virus transport medium, and break the swab rod with the aid of the cap, and put it completely in the tube.

③ Tighten the pipe cover, mark it and put it into a plastic bag for sealing.

How to judge the presence of virus:

We take bacteria as an example.

If the result of ordinary test is positive, it means that the bacteria have been found and the medicine can be applied directly to the case.

However, if the test is negative, it means that the bacteria need to be cultured, and the bacterial culture takes about 24 hours to 48 hours to have results.

The symptoms of viral infection are bacteria, and the results are negative

But this common detection process is long for patients, and throat swab can quickly determine the pathogen at the first visit, and basically determine the medication plan before the patient leaves the hospital.

This is a convenient, noninvasive and rapid examination.

However, it should be noted that this rapid detection is not 100%.

If there is a problem with the quality of throat swab, false negative is likely to occur.
