Abstract: A single housing dual compartment hollow fiber membrane dialyzer for hemodialysis is provided having two coaxially oriented hollow fiber membrane bundles encased within the housing. One of the two compartments within the housing is filled with dialysate. The relative orientations of the membranes and the dialysate simultaneously maximize diffusion, convection and ultrafiltration of fluids, solutes and molecules. During dialyzation, these membranes first separate the blood cells and proteins from the plasma with its toxin solutes and smaller molecules. Then, each blood component is dialyzed separately. Finally, the two components are recombined before being returned to the patient. Since the plasma is not discarded, the need for replacement fluid is substantially reduced or in some cases eliminated.

Abstract: A needle apparatus for intravenous applications which helps prevent needlesticks. The invention includes a needle housing to which a standard hypodermic needle is attached. The needle housing can then be attached to standard syringes via a base. A protective housing surrounds the needle housing which provides two locking positions with the protective housing extended over the needle: the first, is "temporary" which can be removed to restore the needle but still encases the needle, protecting medical personnel from a needlestick; the second is "locked" where the needle cannot be re-exposed, again protecting medical personnel. The protective housing is fitted with a Luer lock so that the apparatus can be used to connect to an I.V. line without requiring the removal of the needle.

Abstract: A catheter apparatus for intravenous applications, such as hemodialysis, which helps prevent needlesticks. The invention includes a hollow plunger to which a hollow needle is attached. A housing surrounds the plunger and contains a locking device so that when the plunger is retracted and the needle is pulled within the housing, the plunger becomes locked into place, thus encasing and securing the needle. A standard IV tubing line is attached to the apparatus, the introducing needle inserted so that the catheter is placed in position, and then the introducing needle is withdrawn and locked in place without the need for the operator having to break the system. Once the needle is locked into position, medical personnel are protected from a needlestick as the entire needle is within the apparatus.
