Description

Technical Field

[0001] The utility model relates to the technical field related to leak detection instruments, in particular to a bioprocess bag integrity tester. Background Art

[0002] In the modern packaging industry, the quality and safety requirements for product packaging are becoming increasingly stringent. Especially in sensitive areas such as biological tubes, medicines, and food, the sealing and integrity of packaging bags are directly related to product quality and consumer safety. Therefore, how to accurately and efficiently detect the side leakage of packaging bags has become an important issue that needs to be solved in the industry.

[0003] After a massive search, it was found that the prior art publication number is CN220288931U, which discloses a glove leak detector, which includes an upper shell unit and a lower shell unit from top to bottom, the upper shell unit includes an upper shell, and the lower shell unit includes a lower shell covered and installed together with the upper shell; the first air pump is connected to the first inflation port of the outer test connection flange through a pressure difference sensor, the first inflation port is connected to the annular inflation sealing ring, the external air source is connected to the second inflation port of the outer test connection flange through the air inlet port and the second air pump in turn, and the pressure sensor is connected to the third inflation port of the outer test connection flange. The utility model uses two air pumps to inflate the sealing ring and the glove separately, and the two do not interfere with each other, which can improve the inflation efficiency; after the detection is completed, the sealing ring is deflated by the first air pump, thereby accelerating the shrinkage of the sealing ring and facilitating the removal of the glove from the sealing ring.

[0004] In summary, the existing testing instruments lack calibration processing before testing the process bags to be tested, and the detection flange connection installation method of the gloves is not suitable for the process bags to be tested.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a bioprocess bag integrity tester to make it more valuable for industrial use. Utility Model Content
