Abstract: In general, the confirmation of a puncture in a blood vessel is made through a visual check of flush back of the blood from the blood vessel into a puncture needle assembly. The conventional puncture needle assembly incorporates a membrane filter permeable to air but impermeable to blood, in order to prevent the blood from flooding outside. The conventional puncture needle, however, cannot be used suitably for the puncture of a blood vessel deep in the tissue. In the puncture needle assembly of the invention, an air relief opening is formed in a portion of a puncture needle hub, catheter hub or an end plug attachable to the puncture needle hub or the catheter, hub other than the portion which constitutes a pressing surface on which the thumb of the user is placed to exert a thrust force for puncturing the tissue and the blood vessel, as in the case of ordinary syringes.

Abstract: Various embodiments of a diaper adapter to fit adults as well as infants up to three years of age comprise absorbent material having an inner surface adapted to contact the user and an outer surface. Tabs carrying a filamentary type attachment material extend from the corners at one end of the diaper. At the opposite end, an elongated bar of a complementary filamentary type attachment material is on the inner surface of the diaper and parallel to the end. The bar, termed a "frontal movable fastening bar", is front folded onto the outer surface of the diaper and moved longitudinally toward the middle of the diaper until the proper length for the user is established. Side portions of the diaper are optionally folded to the proper width and the tabs are pulled around the waist and coupled to the bar.

Abstract: The invention provides a disposable urinary and fecal waste containment product suitable for active adults. The product has a high liquid impact capacity, high liquid retention, contains fecal waste without leakage and allows the skin of the wearer to remain dry. The product has a liquid-impermeable substantially flexible shell containing a superstructure associated with an absorbent medium and a rear portion with a superstructure of three-dimensional characteristics with sufficient friction to prevent movement of fecal matter laterally.

Abstract: An intravenous needle with a sharpened distal end has a proximal end fixed within a first enlarged end of an inner tube. The enlarged end of the inner tube is held tightly within a first end of an outer tube by friction. The needle passes through a constricted opening in the first end of the outer tube. The second end of the inner tube passes through a constricted opening in the second end of the outer tube. The needle is used by gripping soft plastic wings on the outer tube and removing a needle cover from a nipple on the first end of the outer tube. The needle is then inserted in the desired location and the outer tube and a protruding end of the inner tube are taped in place. Fluids are permitted to flow through the inner tube and needle. When use is complete, the needle is removed from the vein, the protruding end of the inner tube is pulled outward, pulling the first end of the inner tube and the needle into the outer tube.

Abstract: A connector including a base and first and second tubular members projecting in generally opposite directions from the base. Each of the tubular members has a longitudinal passage therein, and the passages are communicable with each other. The base can be coupled to first and second containers to place the first and second tubular members within the first and second containers, respectively, so that communication between the containers can be established. The connector includes a plurality of pointed projections extending away from the base to accommodate certain production tolerances in the containers.

Abstract: A simplified aseptic connector assembly for tubes or conduits to conduct sterile fluids and comprising interconnectable complementary male and female connector members respectively connectable to the ends of tube sections to be connected, one of the members having a socket open at one end and dimensioned to slidably receive the other member which also has an axial socket open at the outer end which is adapted to be received in the socket of the one member, the axial socket in the other member being tapered and complementary in shape to a tubular prong extending axially within the socket of the one member for frictional reception within the tapered socket of the other member and the prong having a piercing tip terminating short of the open face of the open end of one member, each of the open ends of the sockets of the members initially being sealed by membranes to maintain the interiors of the sockets in aseptic condition; the sealed ends of the connector members being adapted to be dipped in a disinfecting so

Abstract: The absorbing wound dressing which is atoxic, tissue compatible and very well adjusted to the shape of the wound, it is easily removable, protecting from infections or reduces infections in that it absorbs, in addition to the wound excudate, bacteria, fungi, toxins, proteins and inflammation mediators and which is therefore suitable for covering and cleaning of strongly wetting, infected wounds, as well as effected areas in skin and tissue diseases, consists of potentially macroporous particulate mixtures of regenerated cellulose and a carboxylate groups containing polysaccharide derivative. For making it, viscose solutions, which contain the polysaccharide derivative are thermically coagulated, purified and dried, after the deformation.

Abstract: A disposable plastic adaptor connects a medicine vial to a needleless injector. It includes a hollow, generally cylindrical body member having a top end and a bottom end, with a wall dividing said hollow body into a generally cylindrical top end cavity and bottom end cavity. The bottom end cavity is adapted to slide over the top end of a medicine vial and the cavity wall includes a plurality of detents which prevent removal of the adaptor from the vial. The top end cavity is adapted to be twist connected to the end of a needleless injector. A fluid connector member is mounted within the body member and it comprises a sharp tipped probe extending axially downwardly within the bottom end cavity and an axial projection with a concave end face extending axially upwardly within the top end cavity. An axial bore extends through the fluid connector member to flow connect the concave end face and the probe tip.

Abstract: A package for materials that are to be mixed just prior to use comprises a squeezable container into which is inserted a barrel containing a plunger. One substance to be mixed is placed within the container. The second substance is placed within a compartment formed within the barrel between a pair of pistons having flexible sealing rings. Telescoping of the plunger rod into the barrel causes the upper piston to advance into the compartment. The advancing upper piston exerts hydraulic pressure causing the lower sealing piston to detach from the barrel allowing internal mixing of the substances into a mixed fluid. By squeezing the container side wall, mixed fluid may be dispensed from a forward end of the plunger rod communicating with the container interior through a series of passageways.
