Abstract: An aspect of the invention, is directed to a luer fitting. The luer fitting may include a male luer, a luer collar disposed about the male luer, and a fulcrum disposed at a base portion of a receptacle between the male luer and the luer collar. Another aspect of the invention, is directed to a breakage resistant fitting. The breakage resistant fitting may include a male portion having a central fluid passage, a supplemental securement portion generally concentric with the male portion, and an annular receptacle between the male portion and the supplemental securement portion. The annular receptacle may include a base region having a mating clearance interspace sized substantially greater than a mating female fitting in a radial direction, or an axial direction, or a combination thereof.

Abstract: A dual chamber syringe (10) comprises an inner cylindrical body (30) having a open end, a closed end with an inner discharge outlet (35) formed therein, and an inner plunger (91) sealingly slideable within the inner body, and an outer cylindrical body (11) enclosing the inner cylindrical body and having an open end, a closed end with an outer discharge outlet (20) formed therein, and an outer plunger (75) sealingly slidable between the outer body and the inner body, the inner discharge outlet extending into the outer discharge outlet such that the inner body is in fluid communication through the outer discharge outlet with the exterior of the inner and outer body.

Abstract: The invention may be said to be directed to a luer fitting. The luer fitting may include a male luer, a luer collar disposed about the male luer, and a fulcrum (148) disposed at a base portion of a receptacle between the male luer and the luer collar. The invention may also be said to be directed to a breakage resistant fitting. The breakage resistant fitting may include a male portion having a central fluid passage, a supplemental securement portion generally concentric with the male portion, and an annular receptacle between the male portion and the supplemental securement portion. The annular receptacle may include a base region having a mating clearance interspace sized substantially greater than a mating female fitting in a radial direction, or an axial direction, or a combination thereof.

Abstract: A catheter introducer (31) which allows a dilator section (33) and a sheath section (32) to be engaged with and disengaged from each other promptly and smoothly. The catheter introducer (31) is composed of a sheath section (32) consisting of a sheath (35) and a sheath hub (34) and a dilator section (33) consisting of a dilator (38) and a dilator hub (36). The dilator hub (36) includes a flange (37) to cover the end of said sheath hub 34) in the state of engagement formed at the distal end of the dilator hub (36), a circular groove (40) formed in the internal circular portion of the flange (37) or in the external circular portion of the sheath hub (34), and a protrusion (39) to be engaged with said groove wherein the protrusion is formed on the external circular portion of the sheath hub or on the internal circular portion of the flange.

Abstract: A disposable indwelling catheter placement unit includes a transparent plastic catheter for insertion into a blood vessel having depth indicating graduations thereon. The catheter is freely slidable into a transparent plastic tubular sheath having a slit line there along. The unit has a transparent inserter having an inner tube connected to a front portion of the inserter. The sheath tube is releasable from around the catheter responsive to movement through the inserter. By pushing the sheath tube forward into the inserter with the fingers while holding the inserter with other fingers, or pulling the split sheath from the inserter, the catheter can be pushed into the blood vessel up to a desired depth while maintaining sterility.

Abstract: A suction tube is adapted to receive an enteral feeding catheter through its lumen and has a longitudinally splittable wall to allow the suction tube to be removed from a patient while leaving the feeding catheter in place. In a modified embodiment, the suction tube has a second longitudinally extending lumen in the wall thereof which may be used for air bleed, sample aspiration and delivery of medication.

Abstract: The present invention provides a catheter assembly for placement in a blood vessel which comprises a catheter body having an opening at the distal tip thereof and provided with a luer-connector at proximal portion and a flexible guide wire inserted into said catheter body and bendingly formed to be J-shaped at the distal tip thereof.
