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.

Abstract: Self-defense device has a charge of liquid, preferably substantially water so that, when the device is actuated, it is heated and expelled from a nozzle to be directed at an assailant. Heating of the water may also develop gas pressure which causes the expelling of the water, or heating may cause boiling to result in both pressurization and water expulsion. Black powder and cordite comprise mixtures which, when combusted, cause heating of the water and expelling of the water by separate gas generation. In other cases, a material can react with the liquid to cause expelling of hot liquid. An example of this is alkaline metal, such as sodium, being admixed with the water when expelling is desired.
