Urine midstream collector capable of being automatically closed by attraction to cut off flow

Abstract

The invention discloses a urine midstream collector capable of being automatically closed by attraction to cut off flow, which comprises a collecting cup, the collecting cup comprises an upper cup cavity and a lower cup cavity which communicate with each other, the upper cup cavity and the lower cup cavity are connected through a flexible connecting tube, a flow cutoff device, an electromagnetic induction block and a trigger circuit are mounted in cooperation in the collecting cup between the upper cup cavity and the lower cup cavity, the trigger circuit is electrically connected with the electromagnetic induction block, and the flow cutoff device and the electromagnetic induction block cooperate with each other and can magnetically attract each other to connect, and are used for opening or closing the flexible connecting tube. The urine midstream collector can conveniently collect a midstream urine sample and increase the data accuracy of urine assay, moreover, in the process of operation, midstream urine and initial stream urine can be stably separated, and the situation that midstream urine and initial stream urine are mixed due to untight closing cannot occur.

Description

technical field [0001] The invention relates to the field of medical equipment and equipment, and more specifically to a urine mid-section collection device that can be automatically sucked in and cut off. 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 colle...

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.
