摘要:
A filling member (43) in a medicament delivery device (1), the filling member (43) includes a first conduit (12) that fluidly communicates with a reservoir (4) and a second conduit (14) that fluidly communicates with a pump (3) and with the first conduit (12), wherein the filling member (43) provides two-way medicament flow that enters the reservoir (4) via the first conduit (12), exits the reservoir (4) into the first conduit (12) and the second conduit (14), and exits the second conduit (14) to the pump (3). The reservoir (4) includes a reservoir tube (44A) having one end that is formed with the reservoir (4), and the reservoir tube (44A) having another end that is press fit to the filling member (43) to establish fluid communication with the reservoir (4).

A disposable cartridge (10) comprising a dialyser or adapted to receive a dialyser and use of said cartridge in a hemodialysis machine (1), wherein the cartridge has a blood flowpath for carrying a volume of blood to be treated in the dialyser and a dialysate flowpath, isolated from the blood flowpath, for delivering a flow of dialysate solution through the dialyser. The cartridge (10) is received in an engine section (4) of the machine (1). The engine section (4) has first and second platens (5, 6) which close when the cartridge (10) is inserted to retain the cartridge (10). Actuators (7) and sensors (8) arranged on the second platen (6) control operating of the cartridge (10).

A medical waste fluid collection cart may include a controller for controlling one or more functions of the medical waste fluid collection cart and a memory coupled to the controller, the memory configured for storing one or more vacuum levels. The graphical user interface may be communicatively coupled to the controller and/or the memory and may be configured to allow a user to monitor and/or control one or more functions of the medical waste fluid collection cart. The graphical user interface may include a user confirmation screen to allow a user to confirm a vacuum setting. Using the confirmation screen, the user may confirm the vacuum setting using a first selection corresponding to a predetermined low vacuum level or a second selection corresponding to a previously used vacuum level.

A cardioplegic agent delivery system comprises a supply reservoir (40) for a cardioplegic agent carrier fluid, a delivery channel from the supply reservoir (40) to an outlet (48), and a pump (50) to flow the carrier liquid in the delivery channel above a minimum driving pressure. The supply reservoir (40) is configured to hold carrier fluid below the minimum driving pressure. The pump (50) is a centrifugal pump configured to receive carrier fluid from the supply reservoir (40) and to flow the carrier fluid to the outlet (48) at a flow rate and above the minimum driving pressure for the delivery of cardioplegic agent. This allows cardioplegia delivery to be managed better.

There is provided an electrically operated aerosol generating system (100) for receiving an aerosol-forming substrate (115). The system comprises a liquid storage portion (113) for storing liquid aerosol-forming substrate, an electric heater (119) comprising at least one heating element for heating the liquid aerosol-forming substrate, and electric circuitry (109) for determining depletion of liquid aerosol-forming substrate heated by the heater based on a relationship between a temperature of the heating element and power applied to the heating element. There is also provided a method in an electrically operated aerosol generating system comprising a liquid storage portion for storing liquid aerosol-forming substrate and an electric heater comprising at least one heating element for heating the liquid aerosol-forming substrate, the method comprising: determining depletion of liquid aerosol-forming substrate heated by the heater based on a relationship between a temperature of the heating element and power applied to the heating element.
摘要:
A fluid infusion device is provided with a cannula spring which functions as an introducer needle, a retraction return spring, and a fluid path. A hollow cannula tubing is wound, bent and sharpened into a shape which allows it to operate as an introducer needle, retraction spring and fluid path in an infusion device. A button is used to insert the introducer needle portion of the cannula spring and a soft catheter, and once the introducer needle portion and catheter have been fully inserted, an engagement between the button and post of the base of the infusion device releases the cannula spring such that the introducer needle portion of the cannula spring automatically retracts, leaving the catheter in the body. An end of the introducer needle portion of the cannula spring remains in fluid communication with the catheter in the body to provide an uninterrupted fluid path.

The present invention relates to an apparatus and method for venting a gas from a liquid, which are applicable to a wide variety of medical liquid delivery systems. The apparatus includes level detectors, a clamp, and a control apparatus operably connected to the level detectors and the clamp. The method includes detecting whether liquid or gas is present at the level detectors, and opening and closing a clamp to vent gas. The present invention also relates to an apparatus and method for controlling pressure differential across a semipermeable membrane by using a pressure sensor, a gas source, a valve, and a membrane.
摘要:
Beschrieben wird ein Verfahren zur Befüllung und Entlüftung einer Vorrichtung zur extrakorporalen Blutbehandlung, wie eines Patientenmoduls in einer Herz-Lungen-Maschine, ohne daran angeschlossenen Patienten. Aus aus einem höher als die Vorrichtung befindlichen Befüllflüssigkeitsbehältnis strömt eine Befüllflüssigkeit durch Schwerkraft über eine venöse Seite der Vorrichtung in ein Reservoir und weiter in eine am unteren Ende des Reservoirs befindliche Blutpumpe. Die Blutpumpe befindet sich unterhalb eines unteren Füllstandsensors des Reservoirs. Bei Erkennung der Befüllflüssigkeit im Reservoir durch den unteren Füllstandssensor wird ein steuerbares Ventil (SKL5) geschlossen, wodurch mittels des steuerbaren Ventils (SKL5) eine venöse Verbindung zwischen Volumengabeeinlass und dem Reservoir getrennt wird und die Befüllflüssigkeit nur noch durch die venöse Linie über einen Bypass zu einem arteriellen Filter hin abfließt, und womit durch den anliegenden Druck über die Schwerkraft der Filter von der Auslassseite retrograd befüllt wird.
摘要:
Various arrangements for determining an atomization element of a nebulizer is dry are presented. The vibratable element of the nebulizer may be energized with an electrical signal that sweeps from a first frequency to a second frequency. While energizing the vibratable element of the nebulizer with the electrical signal that sweeps from the first frequency to the second frequency, a sequence of impedance values of the vibratable element of the nebulizer may be measured. The sequence of impedance values of the vibratable element of the nebulizer may be analyzed to determine if the atomization element of the nebulizer is wet or dry.
