Medical sampling three-way valve

Abstract

The invention discloses a medical sampling three-way valve, and belongs to the technical field of sampling valves. The medical sampling three-way valve is characterized by comprising a valve body (1) and a valve rod (3) which can be arranged in the valve body (1) in an axial sliding manner, wherein a liquid inlet runner (10) and a liquid outlet runner (11) which communicate with each other are arranged on the valve body (1); a sampling runner (13) is further arranged on the valve rod (3); an elastic sealing barrel (6) is arranged on the valve rod (3) in the valve body (1) in a sleeved manner; the lower end of the elastic sealing barrel (6) is in sealing connection to the inner wall of the valve body (1); the upper end of the elastic sealing barrel (6) is in sealing connection to the valve rod (3); and the lower end of the sampling runner (13) is arranged on the side wall of the valve rod (3) in the elastic sealing barrel (6). The medical sampling three-way valve is simple to operate, and does not contaminate a sample; the valve body and the valve rod are good in corrosion resistance, so that pollution on a pipeline is not caused; and the elastic sealing barrel is good in sealing effect, so that the problem that the environment is polluted due to the fact that ozone gas or ozone water leaks through the sampling runner is avoided.

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 pathogens. 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, and the original ozone therapy device is connected to the sampling container 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...

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
