Space expansion urine sampler

Abstract

The invention discloses a space expansion urine sampler, the space expansion urine sampler comprises a bracket, a cover plate, coil springs, a urine sample cup, a urine sample expansion bag, a guide column, a guide rod and a urine collection cup; the bracket has a U-shaped structure; the cover plate is movably installed at the upper end of the bracket; the coil springs are respectively fixed on both sides of the bracket; the upper end of the urine sample cup is provided with overlap plates on both sides; the lower ends of the overlap plates are overlapped with the coil springs; the upper endsof the overlap plates are fixedly provided with the guide column; one end of the guide rod is extended into the guide column, and the other end of the guide rod is movably connected with the lower endof the cover plate; the periphery of the upper end of the urine sample cup is connected with the urine sample expansion bag to fix the urine sample expansion bag, the upper end of the urine sample expansion bag is movably connected to the lower end face of the cover plate, and the urine collection cup is connected through the middle of the cover plate with the urine sample expansion bag. The space expansion urine sampler is ingenious in structure design, and the purpose of expansion and enlarging can be achieved.

Description

technical field [0001] The invention relates to a space retractable urine sampler. Background technique [0002] At present, it is necessary to sample the urine before testing the urine. Nowadays, a large-caliber urine collection cup is basically used in clinical practice and then sent to the urine sample cup. In order to prevent problems such as spillage and pollution of urine, At present, the urine collection cup and the urine sample cup are generally designed in an integrated manner, but there is a problem with the sampler with such a structure, that is, the size of the urine sample cup cannot be enlarged. It is not enough, which leads to cumbersome subsequent operations, and it is necessary to design a urine sampler with a retractable space. SUMMARY OF THE INVENTION [0003] Aiming at the above-mentioned shortcomings of the prior art, the problem solved by the present invention is to provide a urine sampler that is flexible in space, flexibly connected, easy to disass...

Problems solved by technology

[0002] At present, the urine needs to be sampled before the urine is tested. Now, a large-diameter urine collection cup is basically used in clinical practice and then sent to the urine sample cup. In order to prevent urine from spilling, pollution, etc., Nowadays, the urine collection cup and the urine sample cup are generally designed in an integrated manner, but there is a problem with such a sampler structure, that is, the size of the urine sample cup cannot be enlarged. When the collection volume is large, generally a urine sample cup Insufficient, which leads to cumbersome follow-up operations, it is necessary to design a urine sampler with expandable space
