Description

  The present invention relates to a specimen detection extraction container for detecting whether a patient has an infection.

An inspector such as a doctor performs a sample test to detect whether or not the patient has an infectious disease such as influenza virus, adenovirus, or RS virus. For this test, a combination of an extraction container for sample detection and an assay strip is used. For example, the following sample detection extraction container that prevents the occurrence of contamination is used. (For example, refer to Patent Document 1).
A liquid reservoir for storing the sample extraction reagent and a nozzle for dripping the extraction reagent are integrally formed to form a container body. The liquid reservoir is flexible and locally (for example, nasal cavity) Or a swab in contact with the pharynx), the nozzle part is formed with a smaller diameter than the liquid reservoir, and a filter seat is formed between the liquid reservoir and the nozzle part, A sample detection extraction container in which a filter for filtering the extraction reagent is attached to the filter seat, and the periphery of the nozzle portion is sealed with a nozzle sealing cap so as to be opened and closed.

Utility Model Registration No. 3107824

The conventional example has the following problems.
(1) The examiner inserts a cotton ball in contact with the patient's local area into the liquid reservoir that contains the sample extraction reagent in advance, and mixes the wipes adsorbed on the cotton ball with the sample extraction reagent. After that, the dropping operation to the assay strip is performed, but before inserting the cotton ball, the reagent in the liquid reservoir passes through a filter and flows down to a small diameter portion and accumulates. Therefore, after removing the nozzle sealing cap, the first few drops dropped from the nozzle onto the assay strip are dispensed with a reagent that is not mixed with wiping fluid, so the tester goes through the process of discarding the first few drops, Must be dripped onto the assay strip.

(2) Since the upper cap is screwed to the container main body, it is troublesome because the upper cap must be turned and detached from the container main body at the time of inspection. In addition, when the upper cap is removed, there is a problem in hygiene such that the upper cap is lost or dust or the like easily adheres to the upper cap.
(3) Since the upper cap is screwed to the container main body, if the screwing is loosened, there is a possibility that the sample extraction reagent in the liquid reservoir will leak from the screwed portion.

  In view of the above circumstances, an object of the present invention is to provide an extraction container for sample detection that can omit the step of discarding the first few drops when a sample extraction reagent mixed with a wiping solution is dropped onto an assay strip. Another object of the present invention is to provide an extraction container for specimen detection that improves the convenience of the examiner and does not cause liquid leakage.

The present invention is an extraction container for detecting a sample comprising a container main body in which a sample extraction reagent is stored in advance, and a lid attached to the mouth of the container main body; the lid is a mouth of the container main body And a nozzle cylinder connected to the inner plug via a hinge. The top wall of the inner plug is exposed by rotating the nozzle cylinder around the hinge. In addition, an opening means for opening a cotton swab insertion opening into which the cotton ball with the wiping solution is inserted is provided in the top wall, and a filter is inserted inside the nozzle cylinder, The nozzle sealing cap is attached by means such as snap engagement which can be easily attached and detached.

  The inner plug of the present invention includes an outer cylinder that is screwed to the outer peripheral surface of the container mouth portion, and an inner cylinder that is continuous with the outer cylinder and contacts the inner surface of the container mouth portion. The inner plug abutting cylinder part to which the hinge is connected, and the nozzle part which is continuous with the inner plug abutting cylinder part and into which a filter is inserted are provided. The opening means of the present invention is an opening protrusion. The present invention is characterized in that a seal ring is provided on the inner side of the inner stopper abutting tube portion. A locking projection that engages with the nozzle cylinder is provided on the top wall of the inner plug of the present invention. The container body of this invention is characterized by having flexibility. The container body of the present invention is characterized by being transparent or translucent.

  Since the present invention is configured as described above, the sample extraction reagent mixed with the wiping liquid is dropped from the nozzle tube through the filter only when the container body is turned upside down and the nozzle is turned downward. Therefore, it is possible to make an inspection target from the first droplet. Therefore, unlike the conventional example, the step of discarding the first few drops can be omitted.

Further, since the inner plug and the nozzle cylinder are hinge-coupled, unlike the conventional example, it is easy to open and is hygienic without the risk of dropping.
Furthermore, since the inner plug includes an inner cylinder that is continuous with the outer cylinder and contacts the inner surface of the mouth, it is possible to prevent the specimen extraction reagent from leaking. Further, since the seal ring is provided inside the inner plug abutting tube portion, it is possible to prevent the specimen extraction reagent from leaking from this portion.
Furthermore, since the container body is made flexible, it is easy to squeeze the wiping solution and drop it onto the assay strip. Further, since the container body is transparent or translucent, the visibility is improved and the working efficiency is improved.
