Abstract: A thermometry assembly includes a thermometer and a mount for mounting the thermometer on a wall or other support structure. The thermometry assembly has an anti-theft system for deterring theft of the thermometer. The anti-theft system generally includes a counter that counts the number of uses of the thermometer during a period beginning from the time the thermometer was last on the mount. A microcontroller of the thermometer is programmed to disable further operation of the thermometer when a threshold number has been reached or exceeded by the counter. The counter is reset when the thermometer is returned to the mount. The anti-theft system includes a solid-state sensor that is activated by a magnet in the mount. The sensor signals to the microcontroller to reset the counter when it is activated by the magnet.

The valve member can be disposed within the housing for rotation relative thereto.

Abstract: Probe cover cassettes having a plurality of probe covers releasably attached to a frame are capable of being stacked so that probe covers attached to a first of the frames are nested within probe covers attached to a second of the frames. The vertical space occupied by the cassettes is reduced allowing more cassettes to be stacked in a given space. The frames of the cassettes are particularly constructed to resist twisting and bending motion when probe covers are detached from the frames using a tympanic thermometer probe.

The cassette includes a retaining system that can have a detent on the cassette holder and a detent receptacle on the cassette. The detent snaps into the receptacle when the cassette is inserted into the holder. The holder is configured so that grips on the cassettes are readily accessed to grasp and hold the cassettes for removal from the holder.

Abstract: A clamping apparatus of the present invention is used in a medical environment to rotationally and releasably secure a device to a support member. The clamping apparatus includes a device clamp having first and second clamp elements and a connector interconnecting the clamp elements. The clamp elements define a first receptacle for receiving a support and a second receptacle for receiving a mounting structure. At least one clamping element defines a device catch in the second receptacle. The connector is selectively moveable between a first position in which relative rotation between the flexible shaft, device clamp and device is resisted, and a second position in which the device is permitted to rotate without releasing connection to the support. A method of supporting a medical device on a support to permit selective rotation of the medical device relative to a flexible shaft without loss of interconnection is also disclosed.

The administration feeding set comprises flexible patient tubing having a support member at one end and a mounting member including a magnetically-susceptible metallic component at the other end thereof. A sensing arrangement is provided by the flow control apparatus for sensing the proper engagement of the metallic component to the recess of the flow control apparatus. A control means permits operation of the flow control apparatus when the metallic member is properly engaged to recess, while terminating operation when the metallic member is improperly engaged to recess.

Abstract: An apparatus for selectively enabling power including a power supply, and a device having a controller and an input activated by a user. The controller is selectively powered by the power supply. While the device is in a sleep state, a sensing circuit senses activation of the input by the user and enables the power supply to provide power to the controller in response to the sensed activation of the input by the user. A latch circuit causes the power supply to continue to provide power to the controller. The controller is responsive to the sensed activation of the input by the user for enabling the latch circuit and for disabling the latch circuit, thereby reentering the device into a sleep state.

Abstract: A peristaltic pump is able to deliver accurate volumes over the life of a pump set that is operated on by the pump to drive the flow of fluid. The pump delivers fluid in small volumes or aliquots. In order to deliver fluid at any particular selected flow rate, the pump determines how often the rotor will rotate. The pump is able to calculate aliquot volume based on selected flow rate, but also on a factor that compensates for changes in the dimensions of the pump set over its life.
