Abstract: An operatory light fixture having a touchless switch (100) operatively connected to a lamp (210) is disclosed. The touchless switch is constructed to detect a user's hand when positioned in a command location relative to the touchless switch and to respond thereto by operating the lamp. In a preferred embodiment, the touchless switch (100) is an active infrared-type switch, comprising means (110) for emitting infrared light toward a command location, means (116) for detecting infrared light reflected from an object (120) such as a hand which is positioned at or near the command location, and relay means (208) responsively connected to the detection means (116) and operatively connected to the lamp (210). In another preferred embodiment, the touchless switch includes means (130) for discriminating a true signal produced by placement of an object such as a user's hand at the command location, from randomly occurring fluctuations in light intensity in the operatory environment.

Abstract: An improvement to sterilizers of the type including a reservoir (11) for liquid sterilant in which the reservoir (11) has a filling port (25) through which liquid is poured from a dispenser (30) into the reservoir (11). Normally closed valves (61, 41) are provided in the cap (31) of the dispenser (30) and in the filling port (25) of the reservoir (11) for liquid sterilant chemicals. The valves (61, 41) contain structures which are actuated when the valves (61, 41) are coupled to open a liquid travel path between the dispenser (30) and the reservoir (11).

Abstract: In an unplumbed sterilizer, a measured quantity of liquid is introduced into a partially evacuated chamber in a dump period. The liquid quantity is automatically controlled by closing a valve in the additional conduit upon the occurrence of either (a) the chamber pressure attaining a preset value, or (b) elapsing of a preset time, whichever occurs first.

Abstract: A chemical sterilizer system for sterilizing items by vaporizing a liquid chemical sterilant in a sterilizing chamber. Pre-evacuation of the sterilizer chamber enhances the sterilizing activity. Sterilant is injected into the sterilizer chamber from a prefilled shot chamber. Subsequent to the exposure period, spent sterilant is condensed and fresh air is pumped into the sterilizer chamber from a vacuum pump. An automated valving system uses a minimal number of three-way valves and one or more two-way valves to control the fluid flow functions in the sterilization cycle.

Abstract: Structure (10) for evaluating the efficacy of sterilization apparatus using either steam or ethylene oxide as sterilant is disclosed. The structure (10) includes an insert of porous material (12) having a cavity (20) formed therethrough for retaining a biological or chemical indicator (14). The porous material has homogenous porosity throughout. The insert of porous material (12) and indicator (14) are enclosed within an outer covering (16) which is relatively impervious to penetration of gases and which provides restricted pathways to air and sterilant. The outer covering (16) is provided with removable portions which are removed when the structure (10) is used to evaluate ethylene oxide sterilization. Removal of the portions enlarges the existing pathways for ingress and egress of gases which may be appropriate in certain efficacy testing.

Abstract: A pressure vessel (13) in which the air, steam, and liquid exhaust systems are combined. A heating coil (17) causes the pooled water (19) to vaporize. As the steam pressure increases, air exits through a chamber (55) housing a temperature/pressure sensor (39). When the sensor (39) determines all the air has exited, the controller (29) closes the single control valve (37). The controller (29) opens the single control valve (37) after a processing phase, whereby the water (19) and steam exit through the combined exhaust system. The conduit (51, 51a) of the combined exhaust system is directed through a water reservoir (43) via the single control valve (37).
