Abstract: A pressure monitoring device used to monitor for leaks in a tool such as a medical endoscope. The device includes a housing having an internal volume fluidically coupled with an internal volume of the tool to form a combined internal volume. A pump changes the pressure inside the combined internal volume thereby establishing a baseline pressure at a pressure differential from the ambient environment. During operation of the tool, the pressure inside the combined internal volume is monitored for a change exceeding a predefined limit and such a change results in the device issuing an alarm signal indicating a leak has occurred in the tool. The device housing can be directly mounted to the tool, located remotely and connected with a coupling hose, or integrated with an accessory device connected to the tool. Preferably, the pressure differential is negative relative to ambient when the tool is a medical endoscope.

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 is used 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 the device 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 to the 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, or it may be a separate external pump which is connected to the housing. The pressure differential may be positive or negative relative to ambient.
