Linkage type liquid dead-corner-free cleaning device for medical disinfection instruments
ActiveCN112775083AAchieve extrusionRealize water jet cleaningCleaning using liquidsMedical equipmentReciprocating motion
The invention provides a linkage type liquid dead-corner-free cleaning device for medical disinfection instruments, relates to the technical field of medical equipment, and solves the problems that jet cleaning and rotary cleaning cannot be realized through structural improvement and organic combination of jet cleaning and rotary cleaning cannot be realized through structural improvement. The linkage type liquid dead-corner-free cleaning device for the medical disinfection instruments comprises a box body, wherein a placing structure is arranged in the box body, and a cleaning structure is slidably connected to the box body. Due to the fact that the head ends of poke rods make contact with the top end face of a placing plate and the poke rods form a protruding extrusion structure, when a handle moves, reciprocating motion of the placing plate can be synchronously achieved, and then jet spraying at cleaning holes is achieved. Fourthly, bulges are welded on the placing plate in a rectangular array shape, the bulges are of semi-cylindrical structures, and the bulges welded in the rectangular array shape jointly form an auxiliary supporting structure of medical supplies, so that gaps can be reserved between the medical supplies and the cleaning holes.
