General anti-reflux valve for urine collector

Abstract

The invention discloses a general anti-reflux valve for a urine collector. The general anti-reflux valve comprises a valve shell, a valve sheet, a first clapboard, a second clapboard and a limiting device, wherein the valve shell is provided with a urine inlet, a urine outlet and a gas exchanging window, and a valve cavity is limited on the valve shell; the valve sheet is arranged in the valve cavity; the first clapboard, the second clapboard and the limiting device are arranged in the valve cavity; the valve cavity is partitioned into an upper cavity and a lower cavity by using the first clapboard; the upper cavity is communicated with the urine inlet, and is communicated with the lower cavity through a first pore canal which is formed on the first clapboard; the second clapboard and thelimiting device are arranged in the lower cavity; the second clapboard is provided with a second pore canal, so that urine flowing out of the second pore canal flows into the urine inlet; and the limiting device is used for limiting the movement of the valve sheet between the first pore canal and the second pore canal. When the urine collector is inclined due to external force, urine in a urine bag below the anti-reflux tends to flow into the valve cavity of the anti-reflux valve, and the valve sheet is attached to the lower surface of the first clapboard, so that a urine channel is blocked and the urine in the urine bag is prevented from refluxing into an intubation patient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-reflux valve clinically used for collecting urine. Background technique [0002] The urine collector is a commonly used clinical medical device, mainly composed of a catheter, a urine bag, a urine outlet and other devices. When the urine collector with such a structure is used to collect urine from patients who cannot urinate normally, concomitant urinary system infections often occur. According to relevant reports: urinary system infection accounts for about 60%-70% of hospital-acquired infections, and 2%-4% of catheter-associated infections develop into Gram-negative bacterial sepsis. There are about 30,000 people in the world every year. Died from a urinary tract infection caused by the use of a urinary catheter. [0003] Pathogens usually invade through 4 ways to cause urinary system infection: 1. During catheterization, the catheter introduces bacteria from the front...

AI Technical Summary

Problems solved by technology

4. The quality of the catheter itself does not meet the sterile requirements, and there are bacteria in the tube

[0005] From the above medical literature, it can be seen that patients whose urine cannot be discharged normally, after using a catheterization system, are very prone to concomitant infection of the urinary system, which makes it difficult to treat

In addition, the use of the catheterization system also requires the careful operation and comprehensive preventive monitoring of medical staff, which consumes a lot of time and energy
