摘要： A medical probe having a handle with an end cap mounted at the proximal end of the handle for urging ejector wires through the handle and out of the distal end of the handle to push off a probe cover frictionally secured to the probe and overlying a probe shaft. The retention device to retain the probe cover on the probe comprises a lip that forces the probe cover into a different shape. The probe shaft is secured to the handle and is slidable axially within the handle and is urged into a fully extended position by a coil spring mounted in the handle. A cable runs through the end cap for connecting the sensor located in the probe to a measurement and display device, such as a thermometer. The end cap has a radius that assists in relieving stress on the cable.

摘要： A care management system in which the management of the administration of care for patients is automated. Hospital information systems are monitored and the information from those systems is used in verifying the administrations of care to patients. The care management system monitors ongoing administrations for progress and automatically updates records and provides alarms when necessary. The care management system is modular in nature but is fully integrated among its modules. Particular lists of data, such as the termination times of all ongoing infusions, provide hospital staff current information for increased accuracy and efficiency in planning. Features include the automatic provision of infusion parameters to pumps for accurate and efficient configuration of the pump, and providing an alarm when an unscheduled suspension of an infusion exceeds a predetermined length of time. A passive recognition system for identifying patients and care givers is provided.

摘要： A needleless valve (2) is described which avoids the suctioning problems upon deactivation and provides a positive self-purging effect. The valve has a base (4) with a connector (10) for fluid communication attachment to tubing or other device (48), a solid elongated fluid channeling rod (14), and internal fluid flow conduit (38, 42, 46); a flexible hollow expandable and contractible plug fitting (6) over and moveable along the rod (14); and a tubular housing (8) fitting over the plug (6) and attached to the base (4). When the valve (2) is activated by insertion of a nozzle (90) of a fluid source (116), the rod (14) and plug (6) wall cooperate so that as the plug (6) retracts along the rod (14), it is stretched and its interior expanded. Upon deactivation, the plug (6) contracts, the interior volume decreases, and the resiling plug wall forces residual fluid within the valve (2) to be expelled through the outlet, purging the residual fluid from the valve (2).

摘要： An artery applanation actuator (20) for use in a system for noninvasively determining the intra-arterial blood pressure of a user incorporates a fluid actuator (38) to effect movement of a sensor (40). The movement of the sensor (40) is effective for applanating an artery of interest and measuring the stress of the tissue overlaying the artery of interest. Alternative embodiments of the artery applanation actuator are presented wherein an electric motor (84) is used to activate a rotating arm (104) which has a sensor (40) located thereon. The rotation of the arm (104) causes the sensor (40) to contact and press against the tissue overlying the artery of interest. The artery applanation actuator is presented having a protective sheath (102) surrounding the sensor (40) to protect the sensor against inadvertent contact.

摘要： The concentration of air or other agents in a fluid delivery line is determined by monitoring agent signals and processing those agent signals along with information regarding the age of each agent signal. The processor determines a primary agent concentration value based on the received agent signal values, with the primary agent concentration value determined by giving greater weight to more recent agent signal values. Where the primary agent concentration value exceeds a primary threshold value, an alarm signal may be activated. The processor also may determine a secondary agent concentration value, which may be determined from the actual agent signal values instead of the weighted agent signal values. Where the secondary agent concentration value exceeds a secondary threshold value, an alarm signal may be activated.

摘要： This invention is an infusion device (10) with a disposable administration set (12) having a plurality of elongated cam followers (42), which are displaced in a predetermined sequence and forced against a delivery tube (36) when depressed by a pumping mechanism (64). The infusion device (10) includes an optical sensor made up of a light emitter (127) and a light detector (129). The optical sensor is responsive to dimensional changes in the delivery tube (36) for sensing upstream occlusions, downstream occlusions and the presence of an air bubble within the delivery tube (36).

摘要： Flow parameters in a fluid delivery assembly are determined by monitoring pressure responses and processing those responses along with information regarding the fluid flow. In one aspect, a processor controls the pump to pump flow quantities in accordance with a pseudorandom code. Portions of the resulting pressure signal sensed are then decoded in accordance with the pseudorandom code. An estimate of the equilibrium pressure is generated from the decoded pressure values, while a summation of the pressure samples is generated from the undecoded pressure signals. The resistance to fluid flow of the system is determined from the estimated equilibrium pressure and pressure summation. For low flow rates, a processor controls the pump to pump fluid in a series of fluid boluses, with each fluid bolus delivered in the beginning of a separate timeslot. The equilibrium pressure is measured at the end of each timeslot, and a summation of the pressure samples is generated from the pressure signals. For high flow rates, the pump is controlled to vary the flow rate and the change in pressure is divided by the change in flow to directly determine the resistance. A resistance display continuously displays the resistance of the system. The pseudorandom coding and decoding can be used to filter out pressure-response crosstalk caused by multiple fluid infusion segments feeding into a common line.
