Description

Nasopharynx swab of accurate sampling

Technical Field

The utility model relates to a medical detection technology field, concretely relates to nasopharynx swab of accurate sampling.

Background

When detecting substances such as new coronavirus, SARS, H1N1 influenza, avian influenza, respiratory tract viruses such as hand-foot-mouth and the like and enteroviruses, a disposable sampling swab is generally adopted to extract secretion from the nasopharynx part, and after the extraction is finished, the disposable sampling swab with pathogens is inserted into a virus sampling tube storage liquid.

Traditional pharynx swab collection mode is divided into oropharynx swab and nasopharynx swab two kinds: the former uses terylene or calcium alginate swab, when the mouth of a patient makes an 'o' sound, the tongue crosses the root of the tongue to the rear wall of the pharynx, the tonsil recess, the side wall and the like for collection, and an auxiliary tongue depressor is needed when necessary; the latter is rotary collection using dacron or calcium alginate swab to enter nasopharynx from nostril for a moment. Medical personnel need go on with the positive relative direct vision of patient during the collection, and the patient is in the sampling process and easy appearance nausea, vomiting, chocks and sneezes, leads to the sampling in-process patient to erupt a large amount of droplets and aerosol towards medical personnel, has all brought very big virus propagation risk for medical personnel and the crowd of patient's surrounding environment.

Therefore, how to contact the nasal cavity and the inner wall of the oral cavity of the patient in the small area as much as possible can collect a sufficient amount of samples, improve the comfort of the patient as much as possible, avoid discomfort of the patient caused by judging the sampling depth of the nasopharyngeal swab by the personal experience of the medical personnel, and avoid further spreading of the virus by sneezing or coughing of the patient to harm the health of the medical personnel is a technical problem to be solved urgently by the technical personnel in the field.

Through published patent searches, the following comparison documents were found:

a throat swab (CN111227872A) discloses a throat swab, comprising: a sampling assembly comprising a swab head and a swab rod, the swab head disposed at a first end of the swab rod; the protective umbrella takes the swab rod as an umbrella handle and can be spread in a direction back to the swab head. When carrying out pharynx swab sample collection to the patient, the position department of being close to patient mouth nose sets up the protection umbrella and can carry out effective separation to the droplet and the aerosol that the patient splashes to effectively reduce the exposure risk of medical personnel and the pollution of patient to the surrounding environment of collection process, simple structure, the protecting effect is good.

Through analysis, the departure point of the above-mentioned patent publication is different from the problem solved by the present application, and the function and structure are different, and the protective umbrella of throat swab in the above-mentioned patent is easy to block the sight of medical personnel, and if the patient coughs and sneezes, its air current is great in the twinkling of an eye, the generated droplet is not that the protective umbrella of small area can completely block, so the novelty of the present application is not influenced by the above-mentioned patent.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide a nasopharynx swab of accurate sampling, this nasopharynx swab can judge the sampling depth according to patient's age and sex selectivity, and need not the large tracts of land and be stained with and get patient's nasal cavity and oral cavity membrane mucus, has reduced the contact of swab sample end with patient's nasal cavity and oral cavity inner wall, reduces the uncomfortable sense of patient, and simple structure, easily realization.

The utility model provides a nasopharynx swab of accurate sampling, includes handheld round bar, and this one end rigid coupling of handheld round bar has and is used for bonding the cotton velvet and scrapes the toper button head of getting the sampling, and the other end complex of handheld round bar bonds and has anti-skidding cover, and this handheld round bar is close to equidistant system on the circumference outer wall of anti-skidding cover end and has a plurality of scale rings, and makes on the circumference outer wall that handheld round bar is close to toper button head end and have broken groove.

And a plurality of step circles which are arranged at equal intervals are manufactured on the periphery of the conical round head, the peripheral diameter of each step circle is smaller than that of the adjacent conical round head, and a plurality of sampling ring areas with sequentially changed diameters are defined by the periphery of each step circle and the periphery of the conical round head.

The utility model has the advantages and the technical effect be:

the utility model provides a nasopharynx swab for accurate sampling, which is held and positioned by medical staff through the anti-skid sleeve at the end part of the handheld round rod; the sampling depth is determined by the scale ring, the sampling depth of the same group of people (age and sex) is kept the same, and the problem that the patient is uncomfortable due to sampling errors generated by experience and operation techniques of medical workers and even the nasopharyngeal swab is inserted into the mouth and nose of the patient too deeply is avoided; the sampling ring area surrounded by the stepped circle and the conical round head outer wall is used for scraping nasal cavity and oral cavity membrane mucus of a patient, the need for circumferentially rotating and large-area staining of the nasal cavity of the patient like a nasopharyngeal swab in the prior art is avoided, the contact surface between the nasopharyngeal swab and the nasal cavity and the oral cavity inner wall of the patient is reduced, and the possibility of discomfort of the patient is further reduced.

The utility model discloses a nasopharynx swab that possesses end regulatory function can judge the sampling depth according to patient's age and sex selectivity, and need not the large tracts of land and be stained with and get patient's nasal cavity and oral cavity mucous, has reduced the contact of swab sample end with patient's nasal cavity and oral cavity inner wall, reduces the uncomfortable sense of patient, and simple structure, easily realization, is a nasopharynx swab that has higher creative accurate sampling.
