    摘要： A method and apparatus for detecting leaking valves in a volumetric fluid delivery system. The system employs a volumetric chamber divided into two compartments by a moveable membrane, with each compartment having a valved inlet and a valved outlet. In the system, fluid is delivered in discrete increments by alternately opening an inlet and an outlet on opposite sides of the membrane. Between such delivery periods, all valves are closed, and then only a single valve is opened. The membrane is monitored to detect movement while the single valve is opened, indicating a closure failure in one of the supposedly closed valves.

    摘要： A device (10, 50, 60, 70, 80, 90) is used to apply an electric pulse or spike to a patient to treat the patient. The device can have a series of preset treatments programmed therein. A user can select a treatment from menus displayed on a display (100). The impedance of the skin and underlying tissue to be treated can be measured prior to the treatment to locate active areas on the skin for treatment. The impedance measurement can be made at a sufficiently low level to avoid treatment of the patient that could cause a change in the impedance. A phase detector can be used to isolate the capacitance value in the impedance. The charge delivered to the patient can be measured and the device can adjust the charge as the skin impedance varies during treatment to deliver uniform charges to the skin. A variety of probes can be used with the device, with the device automatically detecting the type of probe attached. Multiple electrodes can be used on the probe, which allows the active areas in contact with the probe to be identified prior to treatment to allow the treatment to concentrate on the active areas.

    摘要： An infusion pump incorporates a cassette formed by bonding of two substantially flat sheets. The fluid to be infused to the patient comes into contact only with the cassette. The cassette includes first and second flexible sheets which define a pumping chamber therebetween. The infusion pump is provided with a pumping member having a hub and a plurality of petal-shaped sections extending radially outward therefrom and pivotal relative thereto. A stepping motor can be operated to move the pumping member against the second flexible sheet to decrease the volume of the pumping chamber and pump fluid to the patient. A load cell monitors the force exerted by the stepping motor on the hub. An outlet restriction value is electronically controlled by a second stepping motor in response to the pressure sensed by the load cell to control pumping to a predetermined pressure. The pressure can be selectively varied which permits the use of a low pressure at low flow rates to decrease the time necessary to detect an occlusion in the output lines.

    摘要： A system for sensing flow faults in a membrane system for intravenous fluid introduction is provided. A scanner is pulsed to generate reflected energy signals representative of the position of a membrane within a chamber. The scanner is pulsed both before and after the membrane is commanded to move within the chamber. The signals are then compared by an electronic circuit to determine the difference between them. If there exists a sufficiently large difference between the signals, this indicates that the membrane is moving in response to the command signals and the system is functioning properly. If there exists little or no difference between the signals, this indicates that there is a flow fault in the system, and an alarm is sounded.
