Cabinet door safety device for low-temperature hydrogen peroxide plasma sterilizer

Abstract

The invention discloses a cabinet door safety device for a hydrogen peroxide low-temperature plasma sterilizer, which comprises a cabinet door (1), and a limit switch (2) is installed in a groove (E) above the cabinet door (1). ), a safety cover (3) is installed on the contact of the limit switch (2), and the inner wall of the safety cover (3) is provided with a boss (4), through the through hole (B) of the connecting piece (5) the connecting piece (5) Put it on the small end step shaft of the convex plug (6), tighten the screws to fix the convex plug (6) and the connecting piece (5) on the cabinet door (1), and then fix the connecting piece (5) with screws On the cabinet door (1), when the cabinet door (1) is rising, if there are still unplaced items on the side of the cabinet door (1) or the hand is not pulled out in time, the safety cover (3) will be pressed downward. The force of the limit switch is turned on, and the cabinet door (1) will send a signal to the PLC, so that the cabinet door (1) stops moving, thereby avoiding damage to objects or people.

Description

technical field [0001] The invention relates to a cabinet door safety device, in particular to a cabinet door safety device for a hydrogen peroxide low-temperature plasma sterilizer, and belongs to the technical field of medical disinfection and sterilization equipment. Background technique [0002] At present, with the development of sterilization technology for medical devices, a considerable number of hospitals have adopted methods such as hydrogen peroxide low-temperature plasma sterilization for the sterilization of surgical instruments. Hydrogen peroxide low-temperature plasma sterilization is more environmentally friendly, and the sterilization The agent has no residue, safe and reliable. Hydrogen peroxide low-temperature plasma sterilizers work in a sealed chamber, so it is necessary to set a cabinet door to seal the entire sterilization chamber. The process of sealing and closing the cabinet door is to push the cabinet upward through the push rod. The door is seal...

AI Technical Summary

Problems solved by technology

Hydrogen peroxide low-temperature plasma sterilizers work in a sealed chamber, so it is necessary to set a cabinet door to seal the entire sterilization chamber. The process of sealing and closing the cabinet door is to push the cabinet upward through the push rod. The door is sealed, but there is such a deficiency in the above-mentioned prior art. If the sterilized items are not placed in the process of closing the cabinet door or the hands are not pulled out from the cabinet door in time, the sealed seal will be closed upwards on the cabinet door. Sometimes, the door of the cabinet may press the sterilized object or human hands, which will cause damage to the object or person.
