Description

Sample collection device {SPECIMEN COLLECTION APPARATUS}

The present invention relates to a sample collection device for collecting a sample including sputum.

Sputum test, which is one of the diagnostic methods for viral respiratory diseases such as pneumonia, is a method of using sputum as a sample for testing viral respiratory diseases, and is also used as a test method for COVID-19, which is currently prevalent worldwide. It is becoming.

A sputum test generally uses at least one of an upper respiratory tract sample and a lower respiratory tract sample as a sample. For a test using an upper respiratory tract sample, at least one of a nasopharyngeal smear and an oropharyngeal smear is used as an upper respiratory tract sample.

To collect a nasopharyngeal smear, which is one of the methods of collecting upper respiratory tract samples in general, a swab for examination is inserted into the nostril, the tip of the swab inserted into the nostril is brought into contact with the nasopharynx several times, and the nasopharyngeal smear is sufficiently applied to the end of the swab. It consists of a process of putting a cotton swab with a nasopharyngeal smear into a sample container.

However, in the method of collecting a nasopharyngeal swab, which is one of the above-mentioned methods of collecting an upper respiratory tract sample, the tip of a swab for examination, which is a sample collection tool, is inserted into the nostril of the sample recipient and brought into contact with the nasopharynx several times. There was a problem that the collection subject felt uncomfortable as it was moved several times within the nostril.

In addition, since the test swab, which is a sample collection tool, and the sample container for storing the sample are separated, the process of collecting the sample and the process of storing the collected sample must be performed separately, reducing the efficiency of the labor and time required for the test. Had a falling problem.

Since no separate movement of the part occurs, the discomfort of the collection target can be relatively reduced.

As the sample collected through the sample collection unit is accommodated in the sample receiving unit at the same time as the sample is collected, the time and effort required for sample collection can be relatively reduced.

Those skilled in the art to which the present invention pertains will understand that the present invention can be embodied in other specific forms without changing its technical spirit or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description above, and all changes or modifications derived from the scope of the claims and equivalent concepts should be construed as being included in the scope of the present invention.
