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.

Abstract: A freeze protection plug has latching balls engageable bayonet-fashion with grooves in a fitting. The balls are normally held in engagement with the grooves by a cam, but move inward to release the plug from the fitting when the cam is moved by a thermal actuator carried by the plug. The balls are retained in tapered openings in the wall of the plug to reduce jamming. Helical ramps in the grooves permit the use of a strong, reliable plug ejecting spring, and make manual insertion of the plug easy. Insertion is aided by the ribs of a plastic cap, which facilitate manual grasping and rotation of the plug. A paint shield ring prevents failures resulting from paint bridges adhering both to the plug and to the fitting. A unitary molded lanyard with two oval loops prevents loss of the plug. The seal on the plug is located on the liquid system side of the latching balls and isolates moving parts from the liquid system, and is of small diameter.

As a result of these measures the valve is operated by the connecting plug, so that opening and closing of taps is no longer necessary. The operation of such a connection is therefor greatly simplified.
