Negative-pressure cleaning and disinfecting machine with storage box and cleaning and disinfecting method thereof

Abstract

The invention discloses a negative-pressure cleaning and disinfecting machine with a storage box. The machine comprises a storage box assembly, a liquid inlet device, a liquid inlet control valve, a second pipe connector and a discharge control valve, a second box connector is formed in the storage box assembly, the liquid inlet device, the liquid inlet control valve and the second pipe connectorare in pipeline connection in sequence, and the discharge control valve is in pipeline connection with the second pipe connector and is in parallel connection with the liquid inlet control valve. A movably connected valve element assembly is arranged in the second box connector; and when the valve element assembly is in a normally-closed state, the second box connector can be sealed, during use, an endoscope is placed in the storage box assembly, the second pipe connector and the second box connector are in sealed butt joint, and the valve element assembly is switched to be in an open state. In this way, a disinfectant can enter the storage box assembly from the liquid inlet device through the second box connector to disinfect the endoscope, after disinfection is completed, the disinfectant is discharged through the discharge control valve, then the storage box assembly is taken out, the valve element assembly is switched to be in the normally-closed state again, and therefore the storage box assembly is sealed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a negative pressure cleaning and disinfection machine with a storage box and a cleaning and disinfection method thereof. Background technique [0002] The existing negative pressure washer used for cleaning and disinfection of endoscopes usually places the endoscope in the cleaning tank of the negative pressure washer, and then injects disinfectant for immersion cleaning, but after cleaning, the When the endoscope is taken out, the endoscope will come into contact with the external environment, and secondary pollution will easily occur. Therefore, for the cleaning and disinfection of the endoscope, how to optimize the design of the cleaning machine to avoid the cleaning of the endoscope and Contact with the external environment, thereby avoiding secondary pollution, is a problem to be solved at present. Contents of the invention [0003] Aiming at the above-mentioned deficie...
