AI Technical Summary

Technical Problem

During the syringe detection process, the pressure change range is large, which affects the accuracy of the detection result. Especially when the gas leakage amount is small, it is difficult to judge whether there is leakage in the syringe by the pressure change value.

Method used

A detection device is designed, including a frame, push-top member, container and pressure sensor. The movement of the push rod and piston in the tube body is controlled to control the pressure change of gas, and the pressure sensor is used to detect the pressure change in the container to ensure the detection process. The medium pressure is stable, and the gas leakage can be more easily shown by the numerical variation of the pressure sensor.

Benefits of technology

It effectively solves the problem that the pressure range of large changes in pressure during syringe detection affects the accuracy of the detection result, and can more accurately judge the quality problems of the syringe and the trace leakage of gas.

Abstract

The utility model provides a detection device which is used for detecting an injector, the injector comprises a tube body, a push rod arranged in the tube body and a piston arranged on the push rod, the push rod extends into the tube body from the second end of the tube body, and the detection device comprises a rack connected with the tube body; the pushing piece is connected with the push rod, and the pushing piece drives the push rod and the piston to jointly move in the pipe body; the container is communicated with the pipe body; and the pressure sensor is communicated with the container so as to detect the pressure in the container. According to the technical scheme, the problem that the accuracy of a detection result is affected due to the fact that the pressure change range is large when the injector is detected in the prior art is effectively solved.
