Description

Nasal adapter for sample collection

The present invention relates to a nasal adapter, and more particularly, when a sample is collected by inserting a sample collection swab into the nasal cavity of a subject, the tip of the sample collection swab can be guided into the pharyngeal amygdala in the nasal cavity of the subject so that the sample can be collected smoothly. The present invention relates to a nasal cavity adapter for sample collection that not only makes it possible to make the sample collection correctly, but also prevents pain and injury due to incorrect insertion of the sample collection swab.

BACKGROUND OF THE INVENTION In recent years, the occurrence of diseases caused by viral infections is rapidly increasing.

At this time, since the virus is easily transmitted to others through the patient's droplets, etc., further infection can occur widely, leading to the spread of the disease.

Therefore, it is necessary to rapidly select and isolate patients in the early stages of viral disease outbreaks.

Accordingly, sample collection is being carried out to screen patients with viral diseases.

That is, as shown in FIG. 1, a sample is collected by inserting the sample collection swab 100 as disclosed in Korean Utility Model Publication No. 20-2011-0006452 into the nasal cavity of the examinee, and then the sample is collected using various sample analysis devices. By putting in and analyzing, viral disease infection is determined and viral disease patients are selected.

At this time, it is common for a medical worker to collect a sample to determine whether or not to be infected with a viral disease, but there is a problem that additional infection may occur when a medical worker and a subject come into direct contact during the sample collection process. Sample collection is also being attempted.

On the other hand, when the tip of the swab 100 for sample collection inserted into the nasal cavity during the sample collection process reaches the pharyngeal tonsil 5 through the inferior turbinate 2 in the nasal cavity, the collection of the sample, that is, the nasopharyngeal swab, is smooth. can

However, as shown in FIG. 2, since the middle turbinate 3 and the superior turbinate 4 are located around the lower turbinate 2 in the nasal cavity, the sample collection swab inserted into the nasal cavity depending on the subject's posture ( 100) Since the tip can be inserted into the middle turbinate (3) or the superior turbinate (4) instead of the inferior turbinate (2), it is not only difficult to collect the sample, but also causes considerable pain to the subject and causes wounds in the nasal cavity. there was

For the above reason, in the field, when a sample is collected by inserting the sample collection swab 100 into the nasal cavity of the examinee, the tip of the sample collection swab 100 is guided to the adenoid 5 in the nasal cavity of the examinee so that the sample can be collected smoothly. Although efforts are being made to prevent the occurrence of pain and wounds due to incorrect insertion of the swab 100 for sample collection as well as to make this possible, satisfactory results have not been obtained so far.

The present invention has been proposed to solve the problems of the prior art as described above, and when a sample is collected through the insertion of a sample collection swab into the nasal cavity of a subject, the tip of the sample collection swab can be guided into the pharyngeal tonsil of the subject's nasal cavity. The purpose of the present invention is to provide a nasal cavity adapter for sample collection that not only facilitates sample collection but also prevents pain and injury due to incorrect insertion of the sample collection swab.

In order to achieve the above object, the present invention,

A body that is inserted into the nasal cavity of a subject undergoing sample collection, the outer diameter of a distal end of which is completely inserted into the nasal passage is smaller than the outer diameter of a distal end exposed to the outside of the nasal passage; a front opening formed at the front end of the body to guide the inflow of the front end of the swab for sample collection; a rear opening formed at an end of the body to guide an outflow of the tip of the swab for sample collection introduced through the front opening; And it continues between the front opening and the rear opening, and is bent from the outside to the inside with a constant curvature as the diameter gradually decreases from the front opening to the rear opening, so that the tip of the swab for sample collection is directed to the inner pharyngeal amygdala of the nasal cavity. We propose a nasal adapter for sample collection, characterized in that it comprises a; guide passage.

In the nasal cavity adapter for sample collection according to the present invention, a front opening and a rear opening are formed in a body inserted into a non-vesical part of a subject, and a passage is formed between the front opening and the rear opening. The inflow of the tip of the swab for sample collection can be guided, the outflow of the tip of the swab for sample collection can be guided by the rear opening, and the tip of the swab for sample collection can be guided to the pharyngeal tonsil inside the nasal cavity by the passage, Through the tip of the swab for sample collection, not only can sample collection be performed smoothly, but also erroneous insertion of the swab for sample collection can be prevented, so that pain and injury caused by erroneous insertion of the swab for sample collection can be prevented.

In addition, the nasal cavity adapter for specimen collection according to the present invention has bodies of different sizes so that one of them can be selectively inserted into the non-vesical region, so specimen collection can be performed regardless of the subject's body shape, so that various body types can be obtained. Since a sample can be collected from a subject, its utilization can be increased.

In addition, since the nasal cavity adapter for sample collection according to the present invention has a pair of symmetrical bodies and can be connected to each other by means of a connecting piece, sample collection can be performed by inserting a swab for sample collection through either body. Even when there is a problem on either side of the subject's nasal cavity, sample collection can be performed smoothly.

7 is an exemplary diagram showing the induction of a swab for sample collection through a passage in the nasal cavity adapter for sample collection according to the present invention.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

3 and 4, the nasal cavity adapter (A) for sample collection according to the present invention includes a body 10; front opening 20; rear opening 30; and a passage 40;

The body 10 of the present invention is inserted into the nasal anterior vestibule (1) of the subject who is about to take a sample.

Therefore, the swab 100 for sample collection may be inserted into the nasal cavity via the body 10 .

At this time, the body 10 is formed smaller than the outer diameter of the distal end 12 completely inserted into the non-vesical part 1 compared to the outer diameter of the distal end 11 exposed to the outside of the non-vesical part 1, so that the non-vesicular ( 1) It can be easily inserted into the site.

Here, the body 10 is provided in different sizes, for example, large, medium, and small, and any one of them can be selectively inserted into the non-vesical part (1), regardless of the subject's body shape, its outer surface is non-vesical (1) It can be in close contact with the inside of the site.

On the other hand, the body 10 may be provided in a pair and arranged in a left-right symmetrical form.

At this time, the pair of bodies 10 disposed in a left-right symmetrical form are connected to each other by a connecting piece 50 extending from one outer surface to the other outer surface, as shown in FIG. (10) Loss of either can be prevented.

Here, since the body 10 and the connection piece 50 are formed of synthetic resin, particularly polypropylene, bacterial infection can be prevented during the sample collection process by the antibacterial function of polypropylene itself.

The front opening 20 of the present invention is formed at the front end 11 of the body 10.

Therefore, the inflow of the front end of the swab 100 for sample collection can be guided by the front opening 20 .

At this time, since the front opening 20 is formed to have a larger diameter than the rear opening 30, it is easy to insert the swab 100 for sample collection into the inside.

Here, the front opening 20 is formed with a larger diameter than the rear opening 30, and preferably has a diameter of 6 to 9 mm.

That is, when the diameter of the front opening 20 is less than 6 mm, it may be difficult to insert the swab 100 for sample collection into the inside thereof, and when the diameter of the front opening 20 exceeds 9 mm, the front end of the body 10 As the outer diameter of (11) increases, it may be difficult to insert the body (10) into the non-capsular (1) region, so the diameter of the front opening (20) is preferably formed to be 6 to 9 mm.

The rear opening 30 of the present invention is formed at the distal end 12 of the body 10.

Therefore, the outflow of the front end of the swab 100 for sample collection inserted through the front opening 20 can be guided by the rear opening 30 .

At this time, since the rear opening 30 is formed to have a smaller diameter than the front opening 20, vertical and horizontal flow of the swab 100 for sample collection flowing out through the opening 30 can be suppressed.

Here, the rear opening 30 is formed with a smaller diameter than the front opening 20, and preferably has a diameter of 3 to 5 mm.

That is, if the diameter of the rear opening 30 is less than 3 mm, it may be difficult to outflow the swab 100 for sample collection to the outside, and if the diameter of the rear opening 30 exceeds 5 mm, for sample collection through this The progress of the swab 100 may be directed in an unintended direction, more specifically, to a site other than the adenoid tonsil 5 inside the nasal cavity, and the diameter of the rear opening 30 is preferably formed to be 3 to 5 mm.

The passage 40 of the present invention runs between the front opening 20 and the rear opening 30 .

Therefore, communication between the front opening 20 and the rear opening 30 is made by the passage 40, and the swab 100 introduced through the front opening 20 passes through the rear opening 30. may spill out.

At this time, the passage 40 goes from the front opening 20 to the rear opening 30 and is bent with a constant curvature from the outside to the inside as the diameter gradually decreases, so that the swab 100 passing through it is bent and the tip thereof Since 11 can be directed in a specific direction, more specifically, to the adenoid 5 inside the nasal cavity, the tip of the swab 100 for specimen collection can be naturally guided to the amygdala 5 inside the nasal cavity.

The detailed description of sample collection using the nasal cavity adapter (A) for sample collection according to the present invention is as follows.

Prior to sample collection, as shown in FIG. 6 , the body 10 of the present invention is inserted into the nasal anterior vestibule (1) of the subject.

At this time, the outer diameter of the distal end 12 of the body 10 is formed smaller than the outer diameter of the distal end 11, so that it can be easily inserted into the non-capital area 1.

In addition, the body 10 is provided in different sizes and any one of them can be selectively inserted into the vestibular (1) area, regardless of the subject's body shape, its outer surface is in close contact with the inner surface of the non-vesibular (1) area. can do.

Next, the swab 100 for sample collection is inserted into the nasal cavity of the subject.

At this time, a front opening 20 is formed at the front end 11 of the body 10, and the swab 100 for sample collection can be introduced into the body 10 through the front opening 20.

Here, the front opening 20 is formed with a larger diameter than the rear opening 30, and since the diameter is formed to be 6 to 9 mm, the inflow of the swab 100 for sample collection into the inside can be facilitated. In addition, it is possible to prevent the outer diameter of the front end 11 of the body 10 from becoming excessively large, so that the body 10 can be smoothly inserted into the non-vesical region 1.

In addition, a rear opening 30 is formed at the end 12 of the body 10, so that the tip of the swab 100 for sample collection inserted through the front opening 20 flows through the rear opening 30. It can be done.

Here, the rear opening 30 is formed with a smaller diameter than the front opening 20, and the diameter is 3 to 5 mm, so that the swab 100 for sample collection can flow out smoothly to the outside. In addition, it is possible to prevent the specimen collection swab 100 passing through it from progressing in an unintended direction, that is, to a part other than the adenoid 5 inside the nasal cavity, so that the specimen collection swab 100 can be accurately It can be directed to the adenoids 5 inside the nasal cavity.

In the present invention, a passage 40 is connected between the front opening 20 and the rear opening 30, and communication between the front opening 20 and the rear opening 30 is made by the passage 40. The swab 100 for sample collection introduced through the front opening 20 may flow along the passage 40 and flow out through the rear opening 30 .

Next, a sample is collected by the progress of the sample collection swab 100 inserted into the nasal cavity.

At this time, the passage 40 leading between the front opening 20 and the rear opening 30 goes from the front opening 20 to the rear opening 30 as shown in FIG. It is bent from the outside to the inside with a constant curvature. As the swab 100 for sample collection passing through the passage 40 is bent corresponding to the curvature of the passage 40, the tip 11 moves in a specific direction, more specifically, the inner pharynx of the nasal cavity. Since it can be directed to the tonsil (5), the tip of the swab (100) for sample collection can be naturally guided to the adenoid (5) inside the nasal cavity, so that the sample, that is, the nasopharyngeal swab can be collected smoothly. Incorrect insertion of the tip of the swab 100 for sample collection, that is, insertion of the tip of the swab 100 for sample collection into a site other than the adenoid (5) can be prevented. Pain and injury can be prevented.

On the other hand, in the present invention, the body 10 is provided in a left-right symmetrical pair and can be connected to each other by the connecting piece 50, and the sample is collected by inserting the swab 100 for sampling through either body 10. can be made, so even if there is a problem on either side of the subject's nasal cavity, sample collection can be performed smoothly.

And, in the present invention, the body 10 and the connecting piece 50 are formed of synthetic resin, but may be formed of polypropylene, in particular, bacterial infection can be prevented during the sample collection process by the antibacterial function of polypropylene itself. .
