Abstract:

A method for reducing temperature measurement error in a tympanic thermometer. The present disclosure provides a tympanic thermometer including a heat sensing probe defining a longitudinal axis and an outer surface extending from a distal end of the tympanic thermometer. The heat sensing probe includes a thermally insulating sensor housing extending to a distal end thereof. Can-packaged temperature sensing electronics are mounted at the distal portion of the sensor housing. A thermally conductive nozzle is configured to direct heat flux to the temperature sensing electronics in the distal end of the heat sensing probe. The sensor can preferably include a lip extending radially therefrom and contacting the nozzle at at least one contact point to provide heat flux to the sensor can.

US Classification:

374158, 374208

Abstract:

A probe cover () is provided including a tubular body extending from a proximal end () to a distal end (). The proximal end defines an opening configured for receipt of a distal end of a thermometer. The distal end of the tubular body is substantially enclosed by a film (). The distal end includes at least one end rib () disposed about an inner circumference thereof. At least one end rib is configured to engage the distal end of the thermometer such that the distal end of the thermometer is spaced apart from the film. The body may extend in a tapered configuration from the proximal end to the distal end. The end rib can include a transverse portion disposed along a surface of the film. The end rib may include a longitudinal portion extending along the body. The longitudinal portion may extend proximally along the body and the transverse portion may project along a surface of the film such that the longitudinal portion and the transverse portion cooperate to receive the distal end of the thermometer. The body may define at least one longitudinal rib projecting from an inner surface thereof.

Abstract:

A tympanic thermometer includes a thermally conductive nozzle extending from a distal end of the thermometer. A base of a sensor can is thermally connected to the nozzle to define a path of conductive heat transfer from the nozzle to the base of the can thereby minimizing a thermal gradient between proximal and distal ends of the sensor can when temperature is measured in the ear.

International Classification:

US Classification:

374158, 374209, 374208

Abstract:

A cassette of tympanic thermometer probe covers includes a frame and probe covers releasably attached to the frame. The probe covers can be individually attached over a probe of a tympanic thermometer to protect the probe from contamination. The probe covers are constructed to releasably secure themselves to the probe. The force required to secure the probe covers to the frame is less that the force which is required to detach the probe covers from the frame so that the probe cover is held by the frame while being attached to the thermometer probe. The probe cover is connected to the frame by frangible connections that are arranged to inhibit pivoting of the probe cover when being attached to the thermometer probe. A method of securing a probe cover to a probe of a tympanic thermometer is also disclosed.

Abstract:

There is disclosed a flow control apparatus comprising a housing adapted to load an administration feeding set, and a means for driving fluid through the administration feeding set operatively engaged through the housing and adapted to engage tubing of the administration feeding set. A single motor source is operatively engaged to the means for driving fluid, such as a rotor, and adapted to be engaged to a means for controlling fluid flow, such as a valve mechanism. The single motor source is adapted to control operation of the means for driving fluid or the means for controlling fluid flow through a gear arrangement. The gear arrangement is operatively engaged with the single motor source and the means for driving fluid, as well as adapted to operatively engage the means for controlling fluid flow, and is adapted to non-simultaneously operate the means for driving fluid or the means for controlling fluid flow using a microprocessor that controls operation of at least the single motor source.

Abstract:

A pumping apparatus and pump set for use to deliver a supply of liquid to a patient. The feeding set has a conduit for the nutrient liquid and a safety interlock device associated with the conduit. The pumping apparatus has a pumping device and a control system for controlling operation of the pump. An electromagnetic radiation source is operatively connected to the control system of the pump for emitting an electromagnetic radiation signal in a direction for striking the safety interlock device of the feeding set. The safety interlock device being adapted to affect the direction of the electromagnetic radiation. An electromagnetic radiation detector is operatively connected to the control system for receiving the electromagnetic radiation signal when the direction is affected by the safety interlock device, and provides an indication to the control system that the feeding set conduit is properly positioned in the feeding pump.
