Fully automatic multi-device testing system and method for integrity of filter elements

Abstract

The invention discloses a fully automatic multi-device testing system and method for integrity of filter elements. The device includes a test control device for testing and management work, and at least one detection device which is connected with the test control device to receive a command sent by the test control device, and used for completing test work, and uploading data to the test controldevice, the test control device is connected to a remote personal computer (PC), the test control device includes a first control circuit, a first test valve group, a first external valve group and atouch screen, a first gas source is arranged on the first test valve group, each detection device includes a second control circuit, a second test valve group and a second external valve group, and acorresponding second gas source is connected on the second test valve group. The product of the invention enables a user to test more filter elements and filters at the same time, thus the test efficiency is improved, and the fully automatic multi-device testing system is time-saving and economical. The fully automatic multi-device testing system and method for integrity of filter elements can bewidely applied in the field of pharmaceutical industry and biology for integrity inspection of use or production of membranes, filter elements and filters in sterilizing filtration processes.

Description

Technical field [0001] The invention relates to the field of filter element integrity detection, in particular to a fully automatic multi-machine test system and method for filter element integrity. Background technique [0002] The integrity test of the filter element refers to the integrity test and certification of the filter element for filtering liquid and gas. It is widely used in the membrane filtration system of the pharmaceutical industry and biological fields and the quality control department of each membrane (filter element) manufacturer. my country’s “Good Manufacturing Practice for Pharmaceuticals” (GMP) stipulates that “After the sterilization filter is used, its integrity must be checked and recorded immediately by appropriate methods. The usual methods include bubble point test, diffusion flow test or pressure Keep testing.” Therefore, filter integrity testing is widely used in the pharmaceutical industry and biological fields. [0003] At present, domestic filter...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic filter elements have generally transitioned from manual testing to instrument automatic testing. The full-automatic filter element integrity tester is a special instrument for integrity testing of terminal and in-process sterilizing filter materials and filters. However, at present, such integrity The tests are all in the stand-alone test stage, and only one test can be performed on the filter element at the same time, and the test efficiency is low
