Problems solved by technology

However, if cleaning and disinfection is performed in the presence of a leak, the interior of the endoscope may become filled with cleaning fluid or other chemicals, resulting in higher repair costs
Also, if the leak goes undetected and the endoscope is used in surgery, the patient could be exposed to chemicals or other hazardous substances

Embodiment Construction

[0025] The following discussion of embodiments of the present disclosure of devices and methods for monitoring differential pressure is merely exemplary in nature and is in no way intended to limit the disclosed devices or their applications or uses. For example, the invention is described in the context of an endoscope, but it is contemplated that the invention can be used with many types of tools. With respect to the disclosed methods, the steps presented are exemplary in nature, and thus steps may be added, removed or reordered without departing from the spirit and scope of the invention.

[0026] As mentioned above, real-time endoscope leak testing is required during surgery so that once a leak is detected, the surgeon can terminate the procedure and remove the endoscope from the patient as soon as feasible. The device according to the invention uses an innovative device for detecting malfunctions of tools such as medical endoscopes by generating and monitoring a pressure ...

Abstract

A pressure monitoring device is provided for use with a tool such as a medical endoscope. The device includes a housing which is fluidically coupled with an internal volume of the endoscope. A pump isused to change the pressure inside the device housing and endoscope, thereby establishing a pressure differential from the ambient environment. During an endoscopy procedure, the pressure inside thedevice housing is monitored, and a change in pressure exceeding a predefined limit causes an alarm signal indicating a leak has occurred in the endoscope. The device housing may be directly mounted tothe endoscope, located remotely and connected with a coupling tube, or integrated with an accessory device connected to the endoscope. The pump may be integrated internally to the device housing, orit may be a separate external pump which is connected to the housing. The pressure differential may be positive or negative relative to ambient.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of the priority date of U.S. Provisional Patent Application Serial No. 62 / 474,648, filed March 22, 2017, entitled "APPARATUSAND METHOD FOR MONITORING DIFFERENTIAL PRESSURE" . technical field [0003] The present disclosure relates generally to a pressure monitoring device coupled to a closed lumen tool, and more particularly to a device for monitoring pressure to monitor a medical device, such as an endoscope, by generating and monitoring a pressure differential with external atmospheric pressure. Apparatus and method for leak-type failures. Background technique [0004] An endoscope is an illuminated optical instrument, usually a slender and tubular instrument, used to reach deep into the body and for a procedure called endoscopy. Different types of endoscopes have been developed for use in different parts of the body, such as the esophagus, colon, and others. Endoscopes have a v...
