摘要： A twin check valve pumping system for use with a syringe or other variable volume pumping device for the pumping of liquids. Along a flow path between the check valves, a porous, hydrophobic member is positioned, in communication with a portion of the flow path upstream of the first, inlet check valve. The second, downstream outlet check valve is biased so that pressure in the conduit between the check valves is required for expulsion of liquid. When gas enters the system, such pressure cannot be achieved, because, upon attempted pressurization of the area between the two check valves, the gas passes through the porous, hydrophobic member back to a position upstream of the first, inlet valve. However, aqueous liquids cannot pass through the porous member, and accordingly the device pumps such liquids normally in the absence of gas.

摘要： A system and method for controlling a flow is disclosed. The system includes an inlet channel (100, 310) and an outlet channel (200, 320). The inlet channel has an inlet port at a first end configured to be connected to a patient, and a second end with an at least part-annularly shaped aperture (314). The outlet channel has an outlet port at a first end, and an aperture (313) at a second end. The system further comprises a flow channel arranged concentrically outside the at least part-annularly shaped aperture. The flow channel is in fluid connection with the outlet channel. The at least part-annularly shaped aperture of the inlet channel and the aperture of the outlet channel are separated by a seating means (312). The at least part-annularly shaped aperture of the inlet channel and the flow channel are separated by the seating means.

摘要： A multi-use intravenous infusion assembly is presented which includes a septum actuator having various features to prevent over-insertion of the septum actuator through a slit in a blood control septum. By preventing over-insertion of the septum actuator, the slit of the septum is able to repeatedly self-close following removal of an external Luer device. Thus, the intravenous infusion assembly may be used repeatedly without exposing a clinician to blood and other infusion fluids.

摘要： A syringe propellable by propellant that boils at a predetermined temperature, the syringe including a barrel having an outlet at a front end, and a stopper axially moveable in the barrel. The stopper separates a first chamber and a second chamber, the first chamber being axially forwards of the stopper and being configured for containing a medicament, and the second chamber being axially rearwards of the stopper and being configured to receive propellant for acting on the stopper to move the stopper axially forwardly in the barrel to expel medicament through the outlet upon actuation of the syringe. The syringe further includes a rupturing portion and a third chamber for containing propellant where the third chamber is rupturable upon actuation of the syringe to fluidly connect the third chamber to the second chamber. When propellant is released into the second chamber the pressure in the second chamber increases causing the stopper to move axially forwardly to begin expulsion of medicament from the first chamber through the outlet. The syringe is configured such that while the medicament is expelled from the first chamber the pressure in the second chamber changes to a second pressure.

摘要： A sampling connector for use in sampling a body fluid such as arterial blood or cerebrospinal fluid. The sampling connector comprises at least two apertures in fluid communication via a fluid flow conduit and a one-way valve (14) disposed to allow fluid flow from the first aperture, through the fluid flow conduit and out of the second aperture, but not to allow fluid to flow into the second aperture and through the fluid flow conduit to the first aperture. In use, the sampling connector is connected to a body cavity to enable the sampling of a body fluid by withdrawal of the body fluid through the first aperture, and to prevent the introduction of a separate fluid to the body cavity. The first aperture can be within a male end and the second aperture can be within a female end or vice versa. A sampling device comprising a sampling connector according to the present invention and use of the sampling connector and/or sampling device is also claimed.

摘要： A dental syringe may include a replaceable valve cartridge containing one or more valves which may use a seating surface and an opposing seating surface with a relative angle formed between the two surfaces. The relative angle allows for regulation of the flow of fluid. The replaceable valve cartridge may also include a system to remove a residual liquid from a tip of a dental syringe. Additionally, the replaceable valve cartridge may include a seal that prevents bleed-over of fluids. Further, the dental syringe may comprise a tip retention insert which may use either a pair of plates or a plurality of ball bearings to retain the dental syringe tips. An alternate embodiment of a valve may comprise features intended to reduce the force necessary to actuate the valve. A metering screw and/or flow-control groove with increasing depth may control of flow through the valve.
