摘要： This invention is a jet injector (1) for injecting fluid into a body. The jet injection system (703) includes capsules (820, 846) for holding the material to be injected, an apparatus (848) for applying force to the capsule(s) (846) to eject the injection material(s) and a perforator (882) for directing the jet stream for the respective materials into the body. A flyweight (8) system is described for developing injection pressures, and latching devices (18) control the flyweight (8) system. An injector system (840) for injecting more than one fluid is described.

摘要： An angiographic injector (10), preferably in the form of a dual port syringe, has an upper port (78) for connection to a fluid reservoir (22) and a lower port (80) for delivery of the medical fluid under pressure to a patient. A first valve (28) is connected between the fluid reservoir (22) and the upper port (78), and a second valve (26) is connected between the lower port (80) and the patient. During a fill operation, a piston (20) is moved within the syringe (18) to draw fluid from the reservoir (22) into the syringe (18) through the first valve (28) and the upper port (78). The first valve (28) permits air to be expelled from the syringe (18) through the first valve (28) during a purge operation, but blocks flow of fluid the syringe (18) back to the fluid reservoir (22). During injection operation, the piston (20) moves in an opposite direction to force fluid out of the syringe (18) through the lower port (80).

摘要： Die Erfindung bezieht sich auf ein Ventil zum Steuern eines Gas-oder Flüssigkeitsflusses und die verwendung des Ventils bei einer implantablen Medikamentpumpe. Das Ventil ist mit einem Ein- und einem Auslass mit einem Ventilsitz, einem gegenüber dem Ventilsitz verschiebbaren Ventilteil und einer Dichtung dazwischen versehen, wobei das Ventilteil in einer Lage die Dichtung gegen den Ventilsitz drückt und somit den fluß unterbricht. Um ein Ventil dieser Art zu erhalten, das im Aufbau einfach ist und während einer verhältnismässig langen Zeitperiode ein extrem hohes Dichtungsvermögen aufweist, wird erfindungsgemäß vorgeschlagen, daß als Dichtung (12,14,15,17,20,27) zumindest teilweise eine Flüssigkeit mit derartigen Eigenschaften dient, daß sie in der Flüssigkeit bzw. dem Gas, die bzw. das durch Ventil (13,17,24) fließt, unlöslich ist.

摘要： A device for pumping liquids which are highly sensitive to mechanical strains may be conveniently used in hemodialysis, ultrafiltration, hemofiltration and plasma separation apparatuses in order to provide for blood circulation. The pumping device comprises a rigid casing (103; 203) which has a flexible wall part (102; 202) and a sealed cavity (101; 201) with variable volume. The sealed cavity (101; 201) contains a working medium and is connected by means of a conduit (104; 204) to a pressure generator. The rigid casing (103; 203) has also a liquid-tight circulation chamber for the liquid to be circulated, which chamber is provided with supply and discharge conduits (108, 109; 208, 209) and comprises at least a flexible wall part (106; 206). The flexible walls of the casing (102; 202) and of the circulation chamber (106; 206) are arranged facing each other and their surfaces are susceptible of being brought into contact.

摘要： A cassette (20) for use with an I.V. infusion pump (42) has a housing (30) with a first inlet (24), a second inlet (28), an outlet (36), and a port (64) to the I.V. infusion pump. A valve body (60) is positioned within the housing to selectively establish fluid communication from the first inlet to the port, or from the second inlet to the port, or from the port to the outlet. Movement of the valve body within the housing into yet another position allows for the free flow of fluid directly between the first inlet or the second inlet and the outlet.

摘要： A medical pumping system has a supply tube (2), an outlet tube (6), a readily sterilizable, disposable cassette (3) connected to the tubes and engaged with the pump, and means
such as a motor-driven piston, for intermittently applying pressure to the cassette. The pumping system features a display and switch means (9, 10) on a front panel thereof, a pressure sensor, an optical fluid presence sensor, and a microprocessor metering the volume of fluid pumped through said cassette (3), monitoring output signals from said sensors controlling the motor-driven piston in accordance with settings entered via said switch means (9,10), and directing output data to said display means (8). The microprocessor has a stored program for performing SET RATE, RUN, HOLD, VOLUME FED, and CLEAR VOLUME functions. The cassette includes a hydraulically self-actuating inlet valve (44) communicating with the supply tube (2), a hydraulically self-actuating outlet check valve (42) communicating with, and preventing backflow from, the outlet tube (6), a bellows (34) having an interior communicating with the inlet and outlet valves, and a support structure (30,36,38) securing together the tubes, valves and bellows in operating relation. The cassette has an irregularly-shaped cap (38) which prevents in correct insertion into the pump (5).

摘要： A drug delivery pump drive which uses a linear piezoelectric motor to advance a syringe piston to deliver a liquid drug and a method thereof are disclosed. The pump drive, provided in a drug delivery pump, provides silent operation and very low energy consumption compared to electric motor-based drives. The small size of the motor helps also to reduce overall size of the pump drive and the resulting drug delivery pump.

摘要： An Infusion device (1) for administering a medical fluid to a patient, comprises: a housing (10); a receptacle (11) arranged on the housing (10) for receiving a syringe (2); a pusher device (12) movable in a pushing direction (P) for acting onto a piston (21) of a syringe (2) received on the receptacle (11); a drive element (13) connected to the pusher device (12), the drive element (13) being longitudinally movable relative to the housing (10) for moving the pusher device (12) along the pushing direction (P); a driving rod (14) having a screw thread (140) and being rotatable about a rotational axis (R1); an electric drive device (141) for rotating the driving rod (14); a clutching device (130) connected to the drive element (13) and being actuatable, by an actuation device (15), to engage, in a clutched state, with the screw thread (140) of the driving rod (14) for translating a rotational movement of the driving rod (14) into a longitudinal movement of the drive element (13) along the driving rod (14), and to disengage, in an unclutched state, from the driving rod (14); a brake device (16) constituted to act, in an activated state, onto the drive element (13) for braking the drive element (13) relative to the housing (10) and to allow, in a deactivated state, a longitudinal movement of the drive element (13) relative to the housing (10); a control device (17) to control the electric drive device (141) and the brake device (16); and a sensing device (170) for detecting an actuation state of the clutching device (130). Herein, the control device (17) is constituted, when the sensing device (170) detects that the clutching device (130) is actuated to change from the unclutched state to the clutched state, to perform a control sequence during which the control device (17) controls the electric drive device (141) to rotate the driving rod (14) for a predetermined duration or for a predetermined angle of rotation while the brake device (16) is in the activated state.
