Automatic collection device for mid-stream urine

Abstract

The invention discloses an automatic collection device for mid-stream urine. The device comprises a collection cup body. The collection cup body comprises an upper cup cavity and a lower cup cavity, both of which communicate with each other. The upper cup cavity communicates with the lower cup cavity through an annular sleeve pipe body. The annular sleeve pipe body comprises an outer sleeve pipe and an inner sleeve pipe. A fluid passage is formed in an annular passage between the outer sleeve pipe and the inner sleeve pipe. The upper end and the lower end of the fluid passage are respectivelyequipped with an upper check ring body and a lower metal check ring body in a matching manner. The upper check ring body and the lower metal check ring are respectively equipped with multiple throughholes. Electromagnetic attraction force of the lower metal check ring is utilized to automatically and upwardly attract an annular metal check ring of a floating block body. Therefore, the annular metal check ring can be closely connected with the lower metal check ring in an attraction manner. A through hole of the lower metal check ring is blocked so that the upper cup cavity is separated from the lower cup cavity. Therefore, mid-stream urine samples can be conveniently and automatically collected. Data accuracy of urine detection is increased. Additionally, effective and stable separation is achieved.

Description

technical field [0001] The invention relates to the field of medical equipment and equipment, and more specifically to an automatic collection device for mid-urine. Background technique [0002] In most hospitals, urine testing is a relatively routine inspection item, and urine testing is of great value in clinical diagnosis, judgment of curative effect, and recovery after recovery. The existing way of taking urine is to put the urine into the collection container by the subject himself, and then pour it into the test tube. This process is not only inconvenient to collect the middle section of urine, but also inconvenient to operate and easy to pollute the operator. In the process of urine testing and collection, the most accurate diagnostic value of the urine sample is the mid-section urine, but most users cannot automatically collect the mid-section urine using ordinary urine test collection cups, and users need to control the collection by themselves , affecting the accu...

Problems solved by technology

[0004] However, this technical solution still has great shortcomings and deficiencies in actual experiments and applications: first, when the floating block floats upward, the second ring magnet on the floating block cannot be controlled due to the uncontrollable direction of the floating block. The ring is easily attracted to the upper wall of the lower cup cavity, and cannot continue to move to the communication port, resulting in the failure of the communication port to be completely blocked, unable to completely isolate the front urine and the middle urine, and the collection operation fails

Secondly, since the urine is continuously input when the urine is collected, the floating block in the lower cup cavity is subjected to continuous downward pressure, so the second magnetic ring and the protruding ring on the floating block are affected. The second annular magnet ring on the column attracts each other, and the two cannot be smoothly engaged in the actual experiment, which affects the timely blockage of the communication port

Third: When in use, the user needs to screw the ring-shaped connection cover onto the first protruding ring column. In this operation process, not only is the collection cup relatively small, it is inconvenient to operate, but more importantly, This operation process violates the requirements and standards of medical testing. The operator's hand can easily touch the inner wall of the collection cup, causing pollution and inaccurate urine test data.
