摘要： An injection device and method of forming an injection device. The injection device includes a unitary molded body including a cylindrical wall partially defining a syringe chamber a nose offset from the cylindrical wall to define the forward end of a needle housing positioned on one side of the cylindrical wall. The adjoining portions of the nose and the cylindrical wall having a passage formed therethrough for the flow of fluid from the chamber to the nose. The passage is concealed behind the skirt of the nose. A plunger is slidably disposed in the chamber. A sheath is spaced from the nose and cylindrical wall to define a needle housing. A needle carriage is slidably disposed in the needle housing, and is movable to a forward position with the needle extending through the aperture in the front end of the nose.

摘要： An intro-aortic balloon catheter system and method for determining cardiac output with the system including a distal end for insertion into an aorta and a proximal end opposed to the distal end, a balloon portion in proximity to the distal end which repeatedly expands and contracts so as to assist the pumping action of the heart, a catheter tube connected to the balloon portion with the catheter tube having a lumen introducing a pressurized gas into the balloon portion and leading the pressurized gas out from the balloon portion and a temperature sensor attached to the catheter tube and being electrically coupled to a connector at the proximal end of the catheter tube. The method includes inserting the temperature sensor into a lumen of the intra aortic balloon catheter system, advancing the temperature sensor until it projects freely into the aorta, injecting an injectate of a temperature different to that of the temperature of the patient's blood into the central vein of the patient, measuring the blood temperature profile versus time by means of the temperature sensor and calculating cardiac output and optionally the derived variables from the measured temperature profile.

摘要： A syringe system includes a first syringe having a barrel with a tubular tip formed at the end thereof. The tubular tip has an exterior surface with a pair of spaced apart first threads outwardly projecting therefrom so as to at least partially encircle the tubular tip. A second syringe has a barrel with a collar formed at the end thereof. The collar has an interior surface with engagement threads projecting therefrom. The collar is configured to receive the tip of the first syringe such that the first threads can selectively threadedly couple with the engagement threads. A pair of second threads project from the exterior surface of the tubular tip so as to at least partial encircle the tubular tip, the second threads being longitudinally spaced apart from the first threads. The second threads can be rotated, shifted, or otherwise shaped into a variety of different configurations so as to aggressively engage the engagement threads in frictional bias when the first syringe is coupled to the second syringe. In an alternative embodiment, the second threads can be replaced by a ridge which is contigured to frictionally engage with the engagcment threads.

摘要： A hemostasis valve which provides a fluid tight seal at all times to prevent back-bleeding, and offers relatively low friction when devices are inserted therein. The hemostasis valve may either be an integral part of a tubular device (e.g., sheath, catheter, or the like) or releasable from the tubular device (e.g., Y-adapter or the like). In one embodiment, the hemostasis valve is biased to a closed position in response to distal pressure to prevent back-bleeding. The hemostasis valve is also biased to an open position in response to proximal force or pressure to reduce friction when devices are inserted therein. For example, the hemostasis valve may comprise a plurality of leaflets or flaps. In another embodiment, the hemostasis valve is longitudinally actuated between an open position to reduce friction during device insertion and a closed position to prevent back-bleeding when no devices are inserted therein.

摘要： An improved hypodermic needle that greatly reduces the pain associated with injection through the skin that includes a translucent hub for quick observation of flashback, a regular-wall needle with multiple strategically-placed lateral perforations ending with a blade-like honed edge orifice which the remainder of the injection fluid escapes. The increase in localized surface area through which fluid leaves the needle decreases the mechanical distortion of the surrounding tissue thereby lessening pain receptor stimulation and reducing the perception of pain during the injection process.

摘要： A needle holding device having an elongated hollow body with first and second ends, the first end being substantially open for receiving a needle. The hollow body also has a locking member operably disposed therein or thereon. The locking member has an opening to receive and non-releasably hold a needle inserted therethrough. Preferably, the locking member has one or more protrusions directed inwardly toward said opening, the protrusions being adapted to engage a needle in a locking relationship when the needle is inserted through the opening in the locking member. Also preferably, the needle holding device has an elastomeric sealing member operably connected to the hollow body, the elastomeric sealing member also being disposed adjacent the first end of said hollow body. The elastomeric sealing member is adapted to admit and seal around a needle pierced therethrough.
