Correct use of Huachenyang nasopharyngeal swab

Nasopharyngeal swabs are made of special plastic or metal with a long and flexible long handle. The top is make of polyester fiber, rayon and mold nylon.

Sampling of nasopharyngeal swabs is a very common clinical task, which did not appear after the outbreak. Nasopharyngeal swab sampling can be use to assess whether there are respiratory viruses or bacterial infections in adults and children, and is of great significance for the diagnosis of respiratory infections. There are also many influencing factors in the sampling process. If the operation is improper, it will directly affect the inspection results and even lead to misdiagnosis.

Instructions

When sampling a nasopharyngeal swab, the direction of the swab should be parallel to the upper palate, and the tip of the swab should face the direction of the earlobe, not the top of the head. If the swab encounters resistance when passing through the nasal passage, you need to back the swab and try Change the angle and re-enter.

1. The subject’s head is tilted back (approximately 70°) and stays still.

2. Use a swab to estimate the distance between the root of the ear and the nostril.

3. Insert from the nostril straight to the face, and the deepening interval should be at least half the length of the earlobe to the tip of the nose. After encountering resistance, you should reach the nasopharynx, stay for a few seconds to take secretions (generally 15~30s), and rotate the swab 3~5 times.

4. Rotate gently to take out the swab, and put the swab head into the sampling tube containing the virus preservation solution or the cell preservation solution containing RNase inhibitor.

5. Break off the sterile swab rod at the top, discard the tail, screw the cap of the tube tightly and close it with a parafilm.

Precautions:

1. Please do not take antibiotics a few days before the nasal swab.

2. Do not rinse your mouth with disinfectant or smear the local lesion a few hours before the nasal swab.

3. You can’t eat, smoke, or drink a few hours before the nasal swab.

Advantages and collection methods of nasal swabs

Advantages and collection methods of nasal swabs

Advantages of nasal swabs:

1.The nasal swab adopts the spray-type implanted nylon fiber technology, which is first-class in the domestic and foreign markets.

This material can absorb more samples, effectively increasing the collection and release rate of cell and virus samples, and The sample is easier to fall off, so that the final analysis result can be more accurate.

2.The nasal swab adopts a medical ABS plastic rod with a breakable design to facilitate the transportation of specimens.

3.Excellent quality can double the collection effect of swabs, from the 20% sampling and release rate of traditional swabs to the current 95% collection and release rate,

thus ensuring high results reliability.

4.Ethylene oxide sterilization, independent packaging, equipped with virus sampling tube,

convenient transportation of culture medium, and storage at room temperature.

Advantages in nasal swab sampling:

1.It can stay in the pharynx for a longer period of time in order to obtain more sufficient samples.

This is also the reason why the positive rate is higher than that of oropharyngeal swabs reported in the literature.

2.The patient is well tolerated, and can basically take samples without anesthesia after proficient operation,

but the surface anesthesia and contraction of the nasal mucosa can be performed at the beginning.

3.The exposure risk of the sampler is lower than that of the oropharyngeal swab, because when sampling,

we can stand behind the patient and ask the patient to pull down the mask to expose only the nostrils and cover the oral cavity without directly facing the patient’s oral cavity.

And almost no pharyngeal reflex, a few patients may have sneeze reflex after sampling, the patient can be covered by elbow or tissue,

and because the sampler is not in front of the patient, the risk of exposure is lower, so the sampler’s heart pressure will not be so great .

Advantages and collection methods of nasal swabs

Nasal swab collection method:

1.Please keep the patient’s head still and remove the secretions on the surface of the anterior nasal cavity.

2.Use a swab or other tool to measure the distance from the nostril to the base of the ear and mark it with your finger.

3.Gently and slowly insert the swab through the nasal cavity.

4.Swab to the finger mark or stay for a few seconds after encountering resistance to absorb secretions

(usually stay for 15-30 seconds, then gently rotate 3 times).

5.Rotate gently to take out the swab and place it in the virus sampling tube (in the transfer medium);break off the tail rod of the swab along the breaking point to completely place it in the tube. Tighten the cap of the tube.

6.If you need to collect from two nostrils, another swab should be used.

7.Note the information of the person being collected and send it to the inspection room for inspection as soon as possible.
