Abstract: An irrigation syringe which is particularly adapted for injecting water into a human body cavity, such as for the cleansing of an ear, includes a pressure regulator unit which is connected to, and supported by, a faucet, and a handpiece including a manually operable valve. The regulator unit includes a supply chamber having an inlet which is connected to a pressure water supply such as a faucet, an outlet which supplies pressure regulated water to the handpiece, and a pressure relief outlet having a check valve which opens to allow water to drain, such as into a sink, when the water pressure inside the regulator unit exceeds a predetermined value. A flow limiting orifice at the inlet to the supply chamber helps smooth out pressure fluctuations from the water supply and provides a steady flow from the supply chamber outlet. Temperature and pressure readouts are provided on both the pressure regulator unit and the handpiece.

Abstract: Body monitoring apparatus for use with a catheter tube having an outlet opening and a drainage tube having a male connector engageable with the outlet opening of the catheter tube. The apparatus comprises a tubular body member having at one end a male connector engageable with the outlet opening of the catheter tube, at the other end an outlet opening engageable with the male connector of the drainage tube, and an exit from the body member between the connector and the outlet opening. A flexible transmission line extends from a condition sensing transducer such as a temperature sensor through the body member from the male connector thereof through the exit to a point outside the body member. The exit is sealed to prevent leakage of fluid at the point of egress of the transmission line. In another embodiment, the intermediate tube has a window to permit outside observation of the interior of the tube. One or more temperature responsive visual indicators are located in the intermediate tube at the window.
