Problems solved by technology

[0002] At present, the sealing test of medicines has always been in an ambiguous state in the pharmaceutical process. Some people completely believe that the packaging has no leakage or the leakage is within the allowable range and they are directly ignored. This does not comply with the national quality management regulations stipulated by GMP. There are great hidden dangers in the safety of drug use; most of them use the relatively old microbial challenge method, which uses microorganisms to invade the drug to be inspected to test the qualification of the drug. Irreversible damage, no precision data, questionable accuracy of pass / fail test results

Abstract

The invention discloses a sealing test system, and the system comprises a sealed container, a vacuum-pumping device, a detection device, and a PLC controller. The sealed container is provided with a detection cavity and a standard cavity. The detection cavity is communicated with the standard cavity through a first vacuum partitioning valve. The vacuum-pumping device is communicated with the detection cavity through a second vacuum partitioning valve. The detection device is disposed in the sealed container, and is used for detecting a vacuum value of the sealed container. The signal ends of the vacuum-pumping device and the detection device are electrically connected with the PLC controller. Compared with the prior art, the system is simple in structure, is convenient to operate, is high in testing speed and precision, and can precisely obtain a leakage value. In addition, the invention also discloses a sealing test method for testing the sealing degree of a product through employing the above system.

Description

technical field [0001] The invention belongs to the field of food and medicine packaging airtightness detection, and in particular relates to a airtightness test system and a airtightness test method. Background technique [0002] At present, the sealing test of medicines has always been in an ambiguous state in the pharmaceutical process. Some people completely believe that the packaging has no leakage or the leakage is within the allowable range and they are directly ignored. This does not comply with the national quality management regulations stipulated by GMP. There are great hidden dangers in the safety of drug use; most of them use the relatively old microbial challenge method, which uses microorganisms to invade the drug to be inspected to test the qualification of the drug. Irreversible damage, no precision data, questionable accuracy of pass / fail test results. Contents of the invention [0003] The invention provides a sealing testing system and a sealing testin...
