Problems solved by technology

[0002] The traditional leak test method used to detect anesthesia machines uses components such as flow regulating valves, flow meters, and pressure gauges. Each component is independent of each other, and the test process is cumbersome. It is necessary to control multiple components to complete the measurement, and the measurement accuracy is low, and the test effect is poor.

Abstract

The invention discloses a gas leakage measuring instrument. The gas leakage measuring instrument is suitable for being connected with an external gas source and a to-be-measured device and comprises a shell, a pressure reduction device, a proportional valve, a pressure measuring device, a controller and a display screen. The pressure reduction device is disposed in the shell; the proportional valve is arranged in the shell and connected with the pressure reduction device; the pressure measuring device is arranged in the shell and applicable to measurement of internal gas pressure of the to-be-measured device; the controller is respectively connected with the pressure reduction device, the proportional valve and the pressure measuring device and obtains the leakage rate of the to-be-measured device according to a pressure value measured by the pressure measuring device; the display screen is arranged outside the shell and used for displaying measurement information of the gas leakage measuring instrument. The gas leakage measuring instrument has the advantage that by integration of all parts, the leakage rate of the to-be-measured device can be measured conveniently, quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a gas leakage measuring instrument. Background technique [0002] The traditional leak test method for detecting anesthesia machines uses components such as flow regulating valves, flow meters, and pressure gauges. Each component is independent of each other, and the test process is cumbersome. Multiple components need to be controlled to complete the measurement, and the measurement accuracy is low and the test effect is poor. . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a gas leakage measuring instrument, which integrates various components and can measure the leakage of the device under test conveniently, quickly and accurately. [0004] According to the gas leakage measuring instrument of the embodiment of th...
