Connector for endoscope cleaning and sterilizing device, and endoscope cleaning and sterilizing device

Abstract

The present invention is provided with: a connection section for connection to the cleaning and sterilizing device,a flow section (2),and a discharge section (4). The discharge section (4) communicates with the flow section (2) and is provided with: first flow paths (A1, A2) for discharging fluid (R), which has passed through the flow section (2), into a fitting (11),a second flow path (B) branched from the first flow paths (A1, A2) and discharging the fluid (R) around the fitting (11),and an opening and closing section (6) capable of expanding and contracting according to the flow rate of the fluid (R) and expanding to close the second flow path (B) when the flow rate of the fluid (R) is greater than or equal to a set amount, the opening and closing section (6) being provided either in a branch section (8) branched from the first flow paths (A1, A2) to the second flow path (B) or in the second flow path (B).

Description

technical field [0001] The present invention relates to an endoscope cleaning and disinfection device connecting device for connecting an endoscope and an endoscope cleaning and disinfection device, and an endoscope cleaning and disinfection device. Background technique [0002] In the case of using a cleaning and disinfecting device to clean and disinfect the endoscope pipeline, the operator first connects the connecting part of the cleaning and disinfecting device at one end of the connecting device of the endoscope cleaning and disinfecting device to the fluid of the endoscope cleaning and disinfecting device. on the supply port. In addition, connect the spout part provided at the other end of the connecting device of the endoscope cleaning and disinfecting device with the air supply and water supply pipelines and suction pipelines formed on the outer surface of the endoscope and provided inside the endoscope. Connect the tube head of the mirror tube. [0003] As a resu...

Problems solved by technology

However, in recent years, it has been known to have the following structure: no leak-proof member is provided on the discharge part, and a small amount of fluid is intentionally leaked from between the nozzle and the discharge part, which can be used in the cleaning and disinfection process carried out by the cleaning and disinfection device. Use the leaked fluid to clean and disinfect the tube head and its surroundings

[0005] However, in this structure, since the fluid leaks from between the nozzle and the ejection part, there is a problem that in order to reliably clean and disinfect the inside of the endoscope tube, the flow rate of the supplied fluid must be increased compared with conventional ones. resulting in increased cleaning time

[0010] However, in the endoscope washer-disinfector connecting device disclosed in Japanese Patent Application Laid-Open No. 2009-195400, it is necessary to provide a valve element that moves according to the supply amount of the fluid in the ejection part, and must be provided in a direction away from the nozzle. There is a problem that the structure of the spring biasing the valve core becomes complicated.
