Abstract: A pad of elastomeric material having a softness of typically no more than about durometer 50 Shore 00. The pad may carry adhesive and/or a housing for adhering the pad to a surface, either manually, or by adhesive tape, or another strap. Such a pad exhibits hemostatic and leak prevention properties against needle puncture holes in the skin or the wall of a hollow medical device. Particularly, hemostasis may be prevented with low pressure application of the pad to the skin. The pad may be previously applied to the skin of the patient or a wall of a medical device such as tubing or a solution bag, and the needle may then penetrate both the pad and the skin or medical device wall, to make a resealable puncture with leakage reduction and hemostasis when the needle is withdrawn.

Abstract: A medical needle protector sheath comprises a tubular body for surrounding and shielding a needle, with the sheath defining an anchor member integrally attached to the front of the body for manual holding, plus a closure cap for the front end which is integrally attached to the body. Also, a manually removable wing member may be carried about the hub of the needle. A tunnel member typically of the inverted U cross section provides longitudinal securance to the needle and hub while penetrating the skin of the patient while at the same time permitting axial rotation of the needle.

Abstract: A tubular set is provided for the extracorporeal treatment of blood, for example hemodialysis. The set has a patient arterial line and a patient venous line, each line having a patient connector at one end thereof. Each patient line connects at its other end to a reversing flow valve. The valve also connects to respective first ends of a blood processing unit arterial line and a blood processing unit venous line. Each of the unit lines carry a connector at ends opposed to the first ends for connection respectively to arterial and venous ports of a blood processing device, typically a dialyzer. The reversing flow valve has a first position that respectively connects the patient and unit arterial lines with the patient and unit venous lines. The reversing flow valve has a second position that connects the patient arterial line with the unit venous line, and the unit arterial line with the patient venous line.
