摘要： A needle-syringe assembly comprises an elongated, generally cylindrical barrel which forms a hollow nozzle located at the distal end of the barrel and which opens into the interior of the barrel. A plunger is slidably mounted in the barrel and forms a longitudinal cavity. A needle holder carries a hollow needle on the distal end, and the needle holder is slidably mounted in the longitudinal cavity of the plunger. The needle holder includes a lateral arm which extends between the plunger cavity and the barrel. A spiral channel or slot forms a guide surface which extends along a proximal end portion of the barrel for engaging the lateral arm of the needle holder and retracting the needle holder within the barrel in response to relative rotational movement between the barrel and the needle holder.

摘要： A needle-syringe assembly, operable in a normal mode and convertible to a retraction mode, comprises an elongated, generally cylindrical barrel, a plunger slidably mounted in the barrel, and a needle holder carrying a hollow needle on the distal end thereof. The barrel forms a hollow nozzle located at the distal end of the barrel. The plunger forms a coaxial cavity extending therethrough, and the plunger includes a helical slot exposing a proximal portion of the coaxial cavity. The needle holder is slidably mounted in the coaxial cavity of the plunger. During the normal mode, a distal portion of the needle holder is engaged within the nozzle by a taper lock. To switch from the normal mode to the retraction mode, the taper lock is disengaged by rotary movement of the plunger relative to the barrel. While preventing rotary movement of the needle holder relative to the barrel, continued rotary movement of the plunger causes a lateral arm of the needle holder to ascend through the helical slot so that the needle holder retracts into the coaxial cavity of the plunger and the needle is concealed.

摘要： A multiple-lumen intravenous catheter for critical-care applications comprises an elongated cylindrical tube. This tube has a first septum dividing the interior of the catheter into a large lumen having an elliptical cross section, and a smaller lumen having a crescent-shaped cross section. The smallest diameter of the elliptical cross section is larger than the radius of the interior of the catheter. A second septum divides the crescent-shaped lumen into two small lumens.

摘要： A single-use safety syringe assembly comprises an elongated, generally cylindrical barrel which forms a hollow nozzle located at the distal end of the barrel and which opens into the interior of the barrel. A plunger is slidably mounted in the barrel and forms a longitudinal cavity. A needle holder carries a hollow needle on its distal end, and the needle holder is slidably mounted in the longitudinal cavity of the plunger. A biasing arrangement urges the needle holder in a direction for retracting the needle into the barrel. However, a releasable latching arrangement retains the needle holder against the urging of the biasing arrangement in a position wherein the needle projects from the barrel. An In-Barrel assembly sequence is provided which permits sequentially inserting components of the syringe into the barrel and effecting assembly with a push of the plunger. An OTN catheter may also be employed in combination with the syringe assembly.

摘要： A multiple-lumen catheter comprises an elongated cylindrical tube which has an internal diametral septum extending along the length thereof. This septum and the walls of the tube form at least three longitudinal lumens. The first and second lumens have substantially semi-circular transverse cross-sections which occupy the major portion of the transverse cross-section of the interior of the tube. A third lumen has a small transverse cross-section and is located at the intersection of one diametral end of the septum with the tube. This third lumen lies between a pair of adjacent corners of the first and second lumens.

A plunger is slidably mounted in the barrel and forms a longitudinal cavity. A needle holder carries a hollow needle on the distal end, and the needle holder is slidably mounted in the longitudinal cavity of the plunger. The needle holder includes a lateral arm which extends between the plunger cavity and the barrel. A spiral guide slot through a wall of the barrel extends along a proximal end portion of the barrel for engaging the lateral arm of the needle holder and retracting the needle holder within the barrel in response to relative rotational movement between the barrel and the needle holder. A pair of longitudinal ribs strengthen the proximal end portion of the barrel. A locking element for releasably locking the needle holder lateral arm at a distal end of the spiral guide slot is slidably mounted on a track formed on one of the ribs. An OTN catheter may also be employed in combination with the syringe assembly.
