摘要:
An administration feeding set for use with a flow control apparatus to deliver fluid from at least one fluid source to a patient. The set includes tubing for flow of fluid along a fluid pathway and a mounting member on the tubing adapted to engage the flow control apparatus. The mounting member has at least two receiving portions co-axial with the fluid pathway. The set also includes one or more identification members selectively positioned on one or more of the at least two receiving portions of the mounting member to permit identification of the administration feeding set as having a particular functional configuration different from another functional configuration.

A probe cover for a tympanic thermometer probe comprises a generally tubular body having an opening for receiving the thermometer probe and an infrared transparent window at a distal end thereof. In one embodiment, a film support extends radially inward from the distal end of the body and supports an infrared transparent film spanning the window. The film support has an inner edge that is substantially free from corners turning in the plane of the window. A plurality of end ribs are spaced apart and disposed about an inner circumference of the distal end of the body to engage a distal end of the thermometer probe and form an insulating gap by preventing contact of the film by the thermometer probe. The insulating gap also extends proximally into spaces between the end ribs, reducing thermal contact between the thermometer probe and a circumferential inner surface of the probe cover.
摘要:
A method of using a pump set on a pump to deliver a supply of liquid to a patient. The pumping apparatus has a control system for controlling operation of the pump. An electromagnetic radiation source is controlled by the control system to emit an electromagnetic radiation signal in a direction for striking a safety interlock device associated with the pump set. The safety interlock device affects 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 pump set conduit is properly positioned in the pump. The pump is controlled to pump liquid in the pump set only when electromagnetic radiation emitted from the first source is detected by the first detector.

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.

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.

A gastric tube placement device having a carbon dioxide indicator is disclosed. The carbon dioxide indicator comprises a rectangular housing defining a chamber in communication with opposing ports that permits substantial axial flow through the chamber with a carbon dioxide detector disposed therein. A Y-port connector having first and second legs in communication with a main port with a gastric tube coupled to the inside of the connector is provided for insertion of the distal end of the gastric tube through the esophagus of the patient. The carbon dioxide indicator further comprises a carbon dioxide detector disposed inside the rectangular housing which is configured to minimize the dead space inside the housing and facilitates a substantially axial airflow through the carbon dioxide detector when a syringe or similar air-evacuating device is engaged to the rectangular housing and draws air from the housing.

An administration feeding set adapted to be loaded to a flow control apparatus is disclosed. The administration feeding set comprises tubing adapted suitably for fluid flow, a valve mechanism suitable for loading the administration feeding set to the flow control apparatus, and a mounting member adapted suitably for permitting identification of the functional configuration of the administration feeding set. Also disclosed is a method for administering fluid utilizing the administration feeding set. There are also disclosed novel valve mechanisms.
摘要:
A computer system having a shared system memory, and system software in the computer system, are described herein. The computer system has a general purpose, shared system memory that is used for all processing, including video input/output operations, image conversion operations, and rendering operations. In operation, a digital media (DM) Pbuffer is created. The DM Pbuffer is aliased as a DM buffer in the system memory. This is done by storing in a color buffer identifier of the DM Pbuffer an identifier of the DM buffer. Thereafter, all graphical rendering operations directed to the DM Pbuffer are actually performed using the DM buffer.
