Technical Field

The utility model relates to a medical treatment inspection analytical instrument equipment field, more specifically say so and relate to a totally closed urine cup of accurate appearance of giving.

Background

Urine test is called urine test for short, and is a very conventional clinical medical examination; the urine test has very important values for clinical diagnosis, curative effect judgment and prognosis. In the prior art, there are semi-automatic and fully automatic urine test analyzers. Both instruments belong to dry chemical method inspection instruments, so urine analysis test strips are required in the inspection process.

There are some drawbacks to testing with a semi-automatic urine analyzer: 1. the amount of urine soaked into the test strip is not easy to control; 2. the existing test strip is narrow and long, easy to deform and shake and low in test efficiency; 3. the smell of urine or the carelessly splashed urine is not only insanitary and pollutes the environment, but also threatens the health of medical technicians; 4. the operation is complicated and inconvenient, and the labor intensity of medical technicians is increased; 5. used waste urine, waste test paper strips, waste test tubes, waste urine cups and the like are all harmful iatrogenic biomedical wastes.

When the full-automatic urine test analyzer is used for testing, although the steps of taking and dropping the urine sample of the test strip are automated, the odor problem cannot be improved, and medical technicians are also required to participate in a plurality of operations, such as putting a new test strip into the instrument, cleaning the waste test strip, replacing a cleaning solution, cleaning the instrument and the like.

Although the urine cup in patent 2020114437724, a totally-enclosed urine analyzer without manual operation, and patent 2021102403172, a totally-enclosed urine cup for examination and its usage, can partially solve the above problems, the prior art and the above two patents cannot simultaneously satisfy the requirement when the urine sample needs to be accurately given.

Therefore, how to provide a fully-enclosed urine cup with accurate sample feeding, which can overcome the above problems, is a problem that needs to be solved by those skilled in the art.

detection portion, detection portion is including the reaction cavity, test paper strip (08) and colour chip (09), the reaction cavity who adopts transparent material preparation is fixed on the lateral wall of cup (01) and its internally mounted has test paper strip (08), it has a plurality of colour chips (09) to paste on test paper strip (08), a plurality of colour chips (09) are along the length direction interval arrangement in proper order of cup (01), be provided with inlet channel (010) on cup (01), the inside intercommunication of inlet channel (010) and reaction cavity and this tip keep away from bowl cover (02) and a plurality of colour chip (09) simultaneously arrange, another tip and the interior intercommunication of sample cavity of inlet channel (010), when one end terminal surface and circular baffle (05) that piston (03) is close to bowl cover (02) keep away from the one end butt terminal surface of bowl cover (02), inlet channel (010) can be plugged up in piston (03).

2. The fully-closed urine cup with the accurate sample feeding function according to claim 1, characterized in that one end of the cup cover (02) is open and the other end is closed, an internal thread is arranged on the inner side wall of the cup cover (02) close to the open end of the cup cover, an external thread matched with the internal thread is arranged on the outer side wall of one end of the cup body (01) far away from the piston I (03), and the cup cover (02) is screwed on the cup body (01) in a sealing mode.

3. The fully-closed urine cup with the accurate sample feeding function according to claim 1, wherein the reaction cavity is integrally long-strip-shaped, the length direction of the reaction cavity is parallel to the length direction of the cup body (01), the reaction cavity is internally and sequentially divided into a reaction area and a buffer area communicated with the reaction area along the length direction of the reaction cavity, the reaction area is arranged close to the first piston (03), the buffer area is arranged close to the cup cover (02), and the test paper strip (08) and the plurality of color blocks (09) correspond to the reaction area.

4. A fully closed urine cup with accurate sample feeding according to claim 1, wherein when the outer side wall of the piston II (04) and the wall of the through hole (050) start to form a sliding seal, the volume of the sample feeding cavity is smaller than the volume of the reaction cavity.

5. The fully-closed urine cup with the accurate sample feeding function according to claim 1, wherein when the cup body (01) is filled with urine to be detected and the end face of the end, away from the cup cover (02), of the piston I (03) is flush with the end face of the end, away from the cup cover (02), of the cup body (01), part of the urine to be detected flows into the reaction cavity through the liquid inlet channel (010), and a gap is formed between the urine to be detected and the color block (09) farthest from the cup cover (02).
