Abstract: The present invention may provide a specimen collection and storage container comprising: a specimen storage container; a specimen container cover; an insertion coupling part provided on the specimen container cover; and an airtight part provided on the specimen container cover so as to maintain airtightness by bringing the specimen container cover into contact with the specimen storage container when the specimen container cover is coupled to the specimen storage container. According to the above description, fastening force can be secured and airtightness can be improved. Therefore, a medium can be prevented from leaking and being contaminated by the outside.

Abstract: Provided is a specimen collection kit characterized by comprising: a tube body; a coupling member detachably coupled to one side of the tube body; a cover member detachably coupled to the other side of the tube body; and a specimen guide part which is provided on the inner surface of the tube body, prevents an outlet from being clogged by a collection means, and guides the flow of the specimen to the outlet. According to the configuration, blocking of the outlet by a swab is prevented, and thus the specimen can be collected through the outlet without difficulty. Since a maximal amount of the specimen can be acquired when performing a rapid diagnosis, the effects of extraction and diagnostic testing can be enhanced. Since the specimen can be collected by applying a small amount of pressure, fatigue reduction in an inspector can be achieved and thereby make work easier.
