    摘要: A self priming tubing set for infusing a medical solution from an infusion device to a patient includes a supply tube, an air/particle filter, and a restrictor tube. The air/particle filter is adapted to remove air, particularly air contained in the supply tube at the initiation of fluid flow. The air/particle filter also removes particles from the medical solution. The restrictor tube is adapted to reduce the pressure of the medical solution from the delivery pressure of the infusion device to about a mean venous pressure of the patient. The length and inside diameter of the restrictor tube are calibrated to achieve a desired pressure drop dependent on design criteria of the system. The tubing set also includes a slide clamp for closing fluid flow from the supply tube and a connector for connection to a patient interface such as a hypodermic needle or cannula.

    摘要: A wireless-access communications system, such as a CDMA cellular radio-telephone system (FIG. 2), comprises a packet-switched communications network (202, 207, 201) that interconnects cells (base stations; 202) with each other and with the public telephone network (100). Traffic of individual calls is packetized, and packet-bearing frames (300 in FIG. 7) of a plurality of calls are then statistically multiplexed and frame-relayed through the network to yield the high capacity, efficiency, and speed of traffic transport and handoff required for a CDMA cellular system. At each call processing unit (264 in FIG. 5), individual calls are handled by individual service circuits (602 & 612) which perform speech-processing functions such as coding and decoding, tone insertion, and echo cancellation, and packet-to-circuit-switched-PCM traffic conversion. Processors (602) adapt call processing unit timing to compensate for asynchrony between cells and call processing units and variations in call path transmission delays. Cell-to-cell communications, fixed call path addressing, and packetized control message transfers ensure that the same service circuit handles a call through even multiple soft handoffs (FIGS. 27-29) and efficiently communicates simultaneously with all cells involved in the handoff without involvement of system control entities and negative effect on system call-handling capacity. Both coded (packet-switched) and uncoded (circuit-switched) radio-telephone traffic are accommodated side-by-side. Wherever possible, existing and proven technology and component units are used to achieve low cost and high reliability.

    摘要: Heat is removed from the blood flow by heat exchange rather than cold-liquid injection; resulting temperature changes are monitored. Flow rate is found from monitored temperature and known parameters related to the amount of heat removed. Preferably heat is removed by pumping cold liquid into a sealed balloon or sheath along a catheter, which is in the blood stream. The balloon acts as a heat exchanger; its design optimizes that function. Temperature can be monitored by a thermistor or other sensor closer to the tip of the same catheter. Alternatively it appears possible to use blood-temperature measurements taken just outside the balloon, or even within the balloon, if the system is calibrated to account for the relation between the blood flow rate and the heat lost from balloon to blood. Heat removal can be either quasi steady-state or cyclical: that is, either heat is removed semicontinuously by a low-temperature-differential exposure and resulting steady-state temperatures observed semicontinuously; or heat is removed periodically in brief high-differential exposures, and temperature changes tracked in defined time periods during or after each exposure. In the latter case, a patient's heat balance can be maintained by alternately adding heat in protracted low-differential exposures.

    摘要: Apparatus for automatically polling message service systems to obtain messages for a user of the apparatus. The apparatus is a computer attached to the user's telephone connected to a communication switching system. The computer responds to messages from the communication switching system or to an internal real time clock timing out to poll a number of message service systems to obtain messages for the user. The computer automatically performs logon procedures, message access procedures and message deletion procedures with the various message service systems. If the message service system is audio only, the computer generates audio tones and interprets verbal instruction in order to implement the above procedures.

    摘要: A timing system, for distributing clock signals in a synchronous processing system having plural processing sections, includes a central clock circuit and a plurality of section clock circuits, each section clock circuit being located in and associated with a different one of the processing sections. Each section clock circuit is arranged to respond to a system clock signal for stepping through a plurality of states including a state common to the plurality of section clock circuits. An arrangement, responsive to the system clock signal, produces and transmits to the plurality of section clock circuits a synchronization signal that routinely sets the plurality of section clock circuits to the common state. The timing system may further include an arrangement for controlling suspension of processing in the plural processing sections.
