A medical sampling three-way valve

Abstract

A medical sampling three-way valve belongs to the technical field of sampling valves. It is characterized in that it includes a valve body (1) and a valve stem (3) that can slide axially inside the valve body (1), and the valve body (1) is provided with a connected liquid inlet channel (10) and The outlet flow channel (11), the valve stem (3) is also provided with a sampling flow channel (13), the valve stem (3) in the valve body (1) is covered with an elastic sealing cylinder (6), and the elastic sealing cylinder The lower end of (6) is sealingly connected with the inner wall of the valve body (1), the upper end of the elastic sealing cylinder (6) is sealingly connected with the valve stem (3), and the lower end of the sampling channel (13) is set in the elastic sealing cylinder (6). on the side wall of the valve stem (3). The medical sampling three-way valve is easy to operate and will not pollute the sample; the valve body and valve stem have good corrosion resistance and will not pollute the pipeline. Leakage, thereby polluting the environment.

Description

Technical field [0001] A medical sampling three-way valve belongs to the technical field of sampling valves. Background technique [0002] The medical ozone therapy instrument has a broad-spectrum, high-efficiency and rapid sterilization effect, and can fully kill Neisseria gonorrhoeae, Staphylococcus, Candida and various venereal bacteria. Therefore, the medical ozone therapy instrument is suitable for disinfection and sterilization of hospital clinical, environmental and medical equipment. The product is simple to operate, economical and effective, and is a new type of medical device preferred by various medical departments. In the process of using the ozone therapy device, it is necessary to sample ozone gas and ozone water. In the original ozone therapy device, the sampling container is connected in the pipeline, and the pipeline switch is controlled by the solenoid valve to perform the sampling operation. , When sampling, someone needs to individually control the switch of...

AI Technical Summary

Problems solved by technology

During the use of the ozone therapy device, it is necessary to sample ozone gas and ozone water. In the original ozone therapy device, the sampling container is connected to the pipeline, and the pipeline switch is controlled by a solenoid valve to perform the sampling operation. , when sampling, someone needs to control the switch of the solenoid valve separately, resulting in a long sampling time and easily causing sample contamination

In addition, in the actual operation process, due to the corrosiveness of ozone gas and ozone water, the springs in the solenoid valve and the valve body and other accessories are easily corroded. After work, some ozone water will remain in the valve body, and copper rust will occur after a long time. can lead to pipeline pollution, resulting in inaccurate sampling or substandard product quality and other issues
