Closed type urine acquisition machine

Abstract

The invention discloses a sealed urine collector which can lead the patient to use single hand to collect the urine sample and cover the cup cover, thus being convenient, fast, safe and reliable; the collector comprises a cup cover, a cup body and a centrifugal pipe; the inner side of the middle part of the cup cover is provided with a column; the external end of the column is provided with a planar lower piston which is hermetically connected with a circular convex ring which is arranged at the lower part of the middle cup body; one side of the cup cover is articulated with the upper end of the upper cup body by a hinge and the other side of the cup cover is provided with an elastic buckle which is buckled to a fixed buckle at the upper end of the upper cup body; and one side in the circular convex ring is provided with a volume reducing rod which extends downwards.

Description

technical field [0001] The invention relates to the technical field of medical testing instruments, in particular to a closed urine collector. Background technique [0002] Chinese Invention Patent Bulletin discloses a kind of closed urine collector that can directly go on machine, and its patent publication number is CN1820716A. The urine collector includes a centrifuge tube, a cup cover and a cup tube. A funnel is arranged inside the cup tube. mouth, the lower plug attached in the cup cover is sealingly fitted with the lower mouth of the straight pipe. The cup cover matched with the upper end of the cup barrel is provided with a straight rod and a lower plug, which is sealed and matched with the lower opening of the straight tube to obtain a quantitative amount of urine. There are following weak points in above-mentioned technical scheme: [0003] (1) When the patient covers the cup cover, both hands must be operated at the same time, one hand is used to fix the cup tub...

AI Technical Summary

Problems solved by technology

[0003] (1) When the patient closes the lid, both hands must be operated at the same time, one hand is used to fix the cup tube, and the other hand is used to rotate the cup lid or press down the cup lid, which will make it inconvenient for the patient to take samples

If the lid is pressed down, it is easy to loosen the lid and the barrel, splashing urine and polluting the environment

[0004] (2) Since the technical solution is to use the depth of the straight tube to control the sampling volume, when the patient covers the cup cover, the straight tube opening must be aligned first, and then the cup cover is rotated or the cup cover is pressed down, thereby increasing the patient's cup cover. difficulty

At the same time, this structure has high requirements for mold making, and it is difficult to realize

[0005] (3) A handle is attached to the cup cylinder, which will affect the overall appearance and make the mold processing difficult

However, if there is no handle, it will be inconvenient for female patients to take samples
