Abstract

The invention relates to the technical field of biological storage and transportation, in particular to a sealing performance testing device for a biological storage and transportation system, which includes a frame, a storage bag, an air pump and a water storage room. Lowering, a storage bag is embedded in the center of the upper end of the frame, the upper end of the storage bag is spherical, a feeding pipe is provided outside the upper end of the storage bag, and a fixed structure is provided outside the upper end of the storage bag , an air pump is provided on the rear side of the upper end of the frame, and a propulsion structure and an atomization structure are provided inside the water storage chamber; after the storage bag is put into the frame, the storage bag is restricted by a fixed structure The position is fixed, and then the pressure detection equipment is connected to the feeding pipe, and then the air pump is started, firstly in the air tightness detection position, and the air flow is small at this time, which causes a pressure difference between the inside and outside of the storage bag, making the storage bag The air flow inside the bag moves outward to test the tightness of the storage bag.

Description

technical field

[0001] The invention relates to the technical field of biological storage and transportation, in particular to a sealing performance testing device for a biological storage and transportation system. Background technique

[0002] The biological storage and transportation system is a disposable biopharmaceutical processing system composed of bags, components, filters and related accessories. Therefore, the airtightness test of the entire system and the leak test of the components are particularly critical. When using it, it is necessary to use The sealing performance testing equipment detects its sealing, so as to avoid the leakage of the biological storage and transportation system during use, but the general sealing performance testing equipment has some disadvantages in use, such as:

[0003] The general sealing performance testing equipment is relatively cumbersome when testing. Usually, the biological storage and transportation system needs to be put into...
