Abstract

The invention discloses a vibration detecting device for resistance to a dry microbial penetration test. The vibration detecting device comprises a stand, and a vibrating device and a testing device on the stand, wherein the stand comprises a supporting pillar, a damping pillar, a working platform, a pressing plate and a locking piece which are sequentially connected; the testing device comprises a seal cover, a piston, a test piece cover, a tested piece, a container barrel, a petri dish and a petri dish base which are sequentially connected; the vibrating device is arranged on the working platform, and comprises a controller, a frequency sensor, a vibrating motor, a motor fixing base and an eccentric block; the controller is connected to both the frequency sensor and the vibrating motor; the vibrating motor is fixed on the working platform through the motor fixing base; and the eccentric block is connected to the vibrating motor. The vibration detecting device disclosed by the invention can effectively control vibration, and is simple to operate, safe and reliable.

Description

technical field [0001] The invention relates to a microorganism detector, in particular to a vibration detector for a dry state microorganism penetration test. Background technique [0002] According to the standard "YY0506.5-2009 "Surgical Drapes, Surgical Gowns and Clean Clothes for Patients, Medical Staff and Instruments" Part 5: Test Method for Preventing Microbial Penetration in Dry State", the vibration generated in the dry state microbial penetration test is mainly The K13 ball oscillator is driven by compressed air to generate vibration. This pneumatic vibration method requires an external air compressor, the structure of the air circuit is complex, the noise is large and it is difficult to control. In order to effectively protect the experimental results and the experimenters, the whole set of experimental containers needs to be sealed and bagged at the import and export of the petri dish, the import of talcum powder, etc., and the placement and removal of the petr...

This pneumatic vibration method requires an external air compressor, the structure of the air circuit is complex, the noise is large and it is difficult to control

In order to effectively protect the experimental results and the experimenters, the whole set of experimental containers needs to be sealed and bagged at the import and export of the petri dish, the import of talcum powder, etc., and the placement and removal of the petri dish is extremely inconvenient and complicated to operate. Poor reliability; during the vibration process, the existing equipment cannot compress the test piece well, it is easy to slip off and cause pollution, and affect the efficiency of the experiment. For the safety and convenience of the operator, a method that can effectively control the vibration is needed , Easy to operate, safe and reliable testing equipment
