Automatic cover opening and closing device and endoscope washing and sterilizing instrument

Abstract

The invention discloses an automatic cover opening and closing device and an endoscope washing and sterilizing instrument. According to the scheme, the automatic cover opening and closing device mainly comprises a cover body, a cover body opening and closing mechanism and a control part; the cover body is rotationally connected with a covered body, and the control part controls the cover body opening and closing mechanism to drive the cover body to freely open and close relative to the covered body; and the cover body opening and closing mechanism comprises a cover body supporting part and a driving part, the cover body supporting part is connected with the cover body and the driving part, the driving part is controlled by the control part, and the driving part can move in the first direction and / or the second direction and drives the cover body supporting part to move between the opening position and the closing position so as to drive the cover body to move between the opening position and the closing position relative to the covered body. Based on the above scheme, on the aspect of performance, opening and closing driving of the cover body in the positive and negative driving directions can be achieved, and the high stability and reliability of running are guaranteed; and meanwhile, on the aspect of composition structure, the overall structure is simple, and achievement is easy.

Description

technical field [0001] The invention relates to an endoscope, in particular to the cleaning and disinfection technology of the endoscope. Background technique [0002] After the endoscope is used for the purpose of inspection and treatment in the body cavity, not only dirt adheres to the outer surface of the elongated insertion part inserted into the body cavity, but also the air supply and water supply pipes housed inside the insertion part, as well as the Dirt will adhere to various pipes such as the clamp pipe of the suction pipe. Therefore, in order to prevent cross-infection, the endoscope needs to be cleaned and disinfected before it can be used again after use. [0003] In conventional endoscope cleaning and disinfection devices, before cleaning, the operator needs to open the upper cover of the device, place the endoscope to be cleaned in the device, and then close the upper cover to start cleaning. In the past, the upper cover of the device was mostly opened and c...

Problems solved by technology

[0006] Although the existing fixed connection method switch cover structure scheme can quickly realize the opening and closing of the cover body, but because the transmission components in the switch cover structure are relatively fixedly connected, when the driving motor fails, it can only rotate in one direction, making the cover body Will be always open or closed, making it impossible to control the lid from switching between open and closed states
