Negative pressure urine collecting device

Abstract

The invention discloses a negative pressure urine collecting device, comprising a cup body, a cup cover and a negative pressure test tube, wherein the cup cover is connected with the opening of the cup body in a threaded manner; the negative pressure test tube is composed of a test tube, a rubber plug and a splash-proof cap; and vacuum negative pressure is reserved in the negative pressure test tube; according to the negative pressure urine collecting device disclosed by the invention, a cylindrical cavity is arranged at one side of the cup cover facing to the cup body; a self-closed liquid conveying device is arranged in the cavity; the liquid conveying device is connected on the bottom of the cavity and comprises a hollow puncture needle, a connecting pipe and an elastic rubber sleeve; the connecting pipe is upright and is connected in the center of the bottom of the cavity in a sealing manner; the hollow puncture needle is upright and is connected on the inner wall of the port of one end of the connecting pipe in the cavity in a sealing manner; the elastic rubber sleeve is a thin-wall sleeve type component which is provided with an opening at one end, and is idly sleeved on the hollow puncture needle; and the opening end of the elastic rubber sleeve is sleeved on the outer wall of the port of one end of the connecting pipe in the cavity and is matched with the outer wall in a sealing manner. According to the negative pressure urine collecting device disclosed by the invention, the urine sample in the detecting container can be collected in a sealed environment, so as to avoid the secondary pollution; and the negative pressure urine collecting device is safe, convenient and rapid in use.

Description

technical field [0001] The invention belongs to the field of medical supplies, and in particular relates to a urine collection device. Background technique [0002] Urine test items are routine test items in hospitals and are also an important basis for diagnosis. To obtain correct urine specimen testing data, its originality must be maintained during the collection, submission and testing process. As a kind of human body fluid, urine has certain odor and pollution. Urine collection devices are generally used to collect urine, and then sent to the testing room, the test personnel will put the urine into a special testing container from the urine collecting device to complete the collection of urine samples in the testing container. In this process, the operation is cumbersome, and the workload of the operators is heavy; on the other hand, because the urine is not sealed, it is easy to emit peculiar smell, which affects the working environment of the hospital; during the op...

Problems solved by technology

In this process, the operation is cumbersome, and the workload of the operators is heavy; on the other hand, because the urine is not sealed, it is easy to emit peculiar smell, which affects the working environment of the hospital; during the operation of the inspectors, the urine may splash and infect the inspectors, which is also harmful to the environment. Certain pollution, most importantly, may destroy the originality of the specimen, making the error of the detection value larger
