The best flocked swabs in China

The best-flocked swabs in China

We all know that the development of medical enterprises is of great help to society, especially as China’s medical technology improves, the international community has become more concerned about the products involved in China’s medical technology.

Maybe a few years ago, you might still think that medical consumables like flocked swabs that directly contact the sampling site may not be safe to buy in China. May still be biased towards importing abroad, after all, CDC is very strict in the production of flocked sampling swabs. However, the National Health and Medical Commission of my country also has clear requirements for swab materials in the “New Coronary Pneumonia Laboratory Testing Technical Guidelines (Third Edition)”. In addition, the State Council clearly stated in the “Reform Plan for Governance of High-Value Medical Consumables” that “Improve the supervision and management mechanism, and severely investigate and deal with violations of laws and regulations. Improve quality management, strict pre-marketing registration approvals, establish a product information traceability system, and production companies are responsible for lifelong product quality system;”.

flocked swabs are the latest development trend of disposable sample collection equipment. Flocking refers to the use of “spraying technology” to vertically attach millions of nylon fibers to a handle made of ABS material for medical use through electrostatic charges during the flocking process.

In order to improve sample collection, flocking swabs are divided into different types, such as throat swabs, DNA test swabs, gynecological cervical sampling swabs, anal swabs, microbial sampling swabs and so on.
flocked swabs have clear advantages for many applications. According to the research of laboratory professionals, the flocking swab produced by Shenzhen Huachenyang Technology Co., Ltd. has the following five advantages:

(1) Huachenyang’s flocked swab can provide the best sampling:The best flocked swabs in China
Huachenyang’s flocked swabs are a good choice for rapid diagnostic tests because they can better collect cells or organisms at the collection site. And can ensure the rapid release of the entire cell. Huachenyang flocking swabs ensure a higher sampling rate due to its unique manufacturing process.
(2) Huachenyang’s flocked swab can enhance the sensitivity of diagnosis:
Huachenyang has a professional flocking technology to turn each strand of fiber into a velvety brush, thus creating hundreds of thousands of contact points for better collection and release of specimen samples, compared with non-aggregated swabs, because The increase in the number of target cells helps to improve the sensitivity of rapid diagnostic tests.
(3) Huachenyang’s flocked swabs can wash samples quickly
Aggregate swabs are fully integrated processing (which means they do not contain internal fabrics or other cores to absorb the specimen, that is, they will not intercept the sample in the fiber), which not only can collect and retain more samples, but also provides more A good sample collection rate can also release the complete sample into the preservation solution or medium more quickly and completely. The sample is close to the surface, and the sample can be eluted more quickly and completely.
(4) Huachenyang’s exclusive multi-length flocked fiber for flocked swabs
Huachenyang(Shenzhen ) Technology Co., Ltd is not the only manufacturer of medical consumables that provides flocked swabs, but we are the most diligent and sincere wanting to make flocking swabs of the highest quality and the most exquisite style, which is better than traditional cotton, polyester or rayon. The swab collects and retains more specimens.
(5) Huachenyang’s flocked swab has a unique design to facilitate handling and transportation
The flocked swabs we produce have unique breaking points, so you can easily break off the swab tail that grows out of the nozzle by leaning the swab against the nozzle of the virus sampling tube after sampling. Tighten the cap to see it can be safely transported and stored.
Huachenyang(Shenzhen ) Technology Co., Ltd. has always strictly required its own products with the highest production quality standards and is committed to becoming the best manufacturer of flocked swabs in China.

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

What’s the use of disposable sampling swabs

What’s the use of disposable sampling swabs

Disposable sampling swabs are suitable for the collection of microorganisms.

They are not only helpful for the detection of viruses or research of virus samples in hospitals or laboratories,but also can be used for biological samples of human or animal natural cavities,

such as throat, nasal cavity, oral cavity, vagina and other parts.

It can also be used for the detection of human oral or nasal diseases.

It is necessary to collect oral epidermal cells or nasal virus samples with a sampling swab,

and save the cells or samples in the collection tube, and then transfer them to the laboratory for detection.

Here is an example of nasal swab sampling

Nasal swab operation cases:

① Ask the patient’s head to keep still and remove the secretion from the surface of the anterior nostril;

② Gently and slowly insert the swab into the nasopharynx through the nasal cavity;

③ When encountering resistance, they arrive at the posterior nasopharynx and stay for several seconds to absorb secretions;

④ Take out the swab gently and put it in the transport medium;

⑤ For the swab used for virological test,

immerse the head of the swab into the virus carrier solution,

discard the tail, and tighten the tube cover;

⑥ Return the swab to the sampling device or suitable transfer device

The characteristics of Hua Chenyang disposable swabs were as follows

① It is made of non inhibitory DNA amplification material,

which can be verified by direct PCR amplification, and the extraction step is omitted.

② .In order to keep the swab clean and free from contamination, we use the monomer independent packaging

Precautions for collecting nasopharyngeal swabs

Precautions for collecting nasopharyngeal swabs

Why do nasal swabs?

Guangdong has also officially entered the autumn season. Although it is still hot as before, it also feels like the autumn wind is coming. The weather turns cooler, and the temperature difference between morning and evening is large. In this season, it is inevitable that there will be nasal itching and nasal congestion and sneezing. Symptoms. In this special period of this year, we will be very worried about whether we will be infected with the virus. At this time, we will go to the hospital to take a nasopharyngeal swab to see what is going on, then go to the nasopharynx What issues should we pay attention to with swabs? Let’s take a look

Precautions for patients to do nasopharyngeal swabs:

① Please do not take antibiotics a few days before the nose swab;

②Do not use disinfectant mouthwash or smear the local lesion a few hours before the nasal swab

③. Do not eat, smoke or drink for a few hours before the nasal swab.

Note for samplers:

① The sampler stands on the side of the patient to take the sample,

②. The patient is required to pull down the mask to expose only the nostrils. Once the sneeze reflex occurs, the patient can be covered by the elbow or paper towel. The sampler is not in front of the patient, and the exposure risk will be lower.

③. If the patient’s turbinate hypertrophy, nasal passages are narrow, and the nasal swab insertion feels resistance, you can try to change one side of the nasal cavity or directly change to oropharyngeal swab collection.

④. People with nasal allergies are prone to sneezing, and oropharyngeal swab sampling is recommended.

⑤ Remember to wear a protective mask/face screen. For individuals who are highly suspected or basically diagnosed, or have severe coughs and hiccups, they should wear protective clothing.

⑥ After sampling, change gloves, perform hand sanitation and disinfection, and spray disinfectant on areas where the patient has touched.

Well, we still need to pay attention in special periods. Remember to wear a mask and personal hygiene when you go out. Once you find the virus is infected, please isolate it to avoid spreading it again.
