Three-position four-way valve for urine collection device

Abstract

A three-position four-way valve for a urine collection device comprises a main body and a valve element. The main body comprises a connecting seat port and a valve pipe, wherein the valve pipe is respectively communicated with a first pipe, a second pipe, a third pipe and a fourth pipe, the pipe ports of the first pipe and the second pipe are located inside the connecting seat port, the pipe ports of the third pipe and the fourth pipe are located outside the connecting seat port, and the first pipe is always communicated with the third pipe. A first port, a second port, a third port and a fourth port are formed in the peripheral wall of the valve element, the first port and the second port are mutually communicated, and the third port and the fourth port are mutually communicated. The valve element is located inside the valve pipe with the peripheral wall tightly attached to the inner wall of the valve pipe, the valve element and the valve pipe can rotate relatively in three positions around an axis and are relatively fixed in the axial direction. When the valve element is located in the first position, the first port is communicated with the third pipe, the second port is communicated with the second pipe, and the fourth pipe is cut off by the valve element. When the valve element is located in the second position, the second pipe and the fourth pipe are both cut off by the valve element. When the valve element is located in the third position, the third port is communicated with the second pipe, the fourth port is communicated with the fourth pipe, and the position between the first pipe and the second pipe is cut off by the valve element. The three-position four-way valve for the urine collection device has the advantages of being simple to operate and easy to achieve.

Description

technical field [0001] The invention relates to a special component of a medical device, in particular, a special three-position four-way valve for a urine collection device. Background technique [0002] The urine collection device is one of the most used medical consumables clinically. Catheterization devices are often used by patients who cannot urinate normally due to diseases. The general catheterization device includes a catheter for the patient and a urine collection bag for collecting urine. Usually, the nursing staff needs to record the patient's urine output and collect urine. sample to determine the patient's current physical condition. Existing urine collection bags are generally made of flexible materials, but the urine collection bags made of flexible materials cannot accurately measure the stored urine, resulting in a large error between the actual urine volume and the measured urine volume. When collecting urine samples, it is measured by the collection con...
