摘要： A safety needle device includes a housing, a Huber needle, a cap and a sheath. The Huber needle has a first needle leg disposed in the housing and a second needle leg extending perpendicularly of the first needle leg. The cap is disposed over the second needle leg and is movable relative thereto from a first position with the second needle leg extending through the cap to a second position with a tip of the needle disposed in sealed relation in the cap. The sheath is concentrically disposed on and about the needle in a collapsed state, and secured to and between the housing and the cap. The sheath is extendable from the collapsed state to an extended state in response to movement of the cap from the first position to the second position.

摘要： The needle of a syringe, wire guide, biopsy needle, Huber needle and the like is drawn into a protective cap and sheath arrangement after use for disposal purposes. The cap is tethered to a housing in which the needle is mounted by the sheath. The sheath is made of a film material that has a high tensile strength and a low percent of elongation, such as polyester. The sheath is initially mounted about the needle in a collapsed accordion-like condition between the cap and housing. When the cap is moved along the needle, the sheath is played out over the needle. The cap houses a spring clip to snap over the bore through which the needle is retracted to prevent re-emergence of the needle. The flexible nature of the sheath allows the sheath to pass about the two legs of the Huber needle.

摘要： A female luer connector for intravascular or urological use is provided with a needle having a closed distal end with an opening in the side of the needle. In addition, the needle is sealingly received within a recess of a rubber septum with an interference fit between the distal end of the needle and the septum. A slit may be formed in the septum to facilitate penetration of the needle through the septum when in use. In one embodiment, the septum has an elongated recess so that the needle may be received under compression in one portion for storage purposes and in a second portion when in use.

摘要： The shielded cannula assembly includes a tubular shield of latex rubber which is mounted over the cannula of the assembly. The shield includes a resilient collapsible tubular portion which is able to collapse in an accordion-like manner when a longitudinal force is imposed thereon. The shield also has a cap at the distal end which seals off a chamber in which the cannula is contained in a sterile manner. The cap includes a transverse wall which may be pierced by the cannula when the cannula is passed into a vial of medication or into a connector of an administration set.

摘要： This invention pertains to both an apparatus and a method for constructing and using an incontinent female urine collection device. A molding of a partly resilient material and having a cup-shape and a stepped bore in said receptacle, is provided. Several attachment configurations to receive and retain a resilient, soft, compliant outer-rim portion are shown. This rim portion is secured to a lip edge of the molding by adhesive and the like to provide a fluid-tight seal when this device is mounted in the folds of the user's labia. A first length of tubing is secured in a formed stepped bore as by adhesive and/or the like. The discharge end of this tubing is connected to a second tubing conductor leading to a urine collection receiver. A vent in this conductor is provided to prevent air binding. A panty garment having elasticized properties is made with a reinforced aperture sized to accept and retain the first length of discharge tubing. This reinforcement is adapted for resisting wear, raveling and enlargement. The resilient, compliant rim provides a soft, non-irritating fluid-tight seal of the worn collection device to the skin area of the female labia. The receptacle and rim portion thereof may be integrally formed of closed cell silicone foam.

摘要： A post-injection needle sheath for enclosing the sharpened end of a needle used with a syringe is shown with and without spring actuation. This sheath is initially in a compact and secured condition on the needle hub and has a substantial portion of the needle exposed for insertion into a patient or vial. Two embodiments employ a compression spring. Three embodiments avoid a spring per se, but have a corrugated portion and a flange portion that are manipulated by the attendant to urge the sheath forward to enclose the sharpened end of the needle. In all embodiments, the forward end includes a transverse wall in which is formed an aperture that is slightly larger than the shank of the needle. Protection to the exposed needle before use is provided by a conventionally removable shield which is removed at time of use. After withdrawal of the needle from the patient, the sheath, with the cap or end portion, is moved forward to enclose the sharpened needle.

摘要： This invention pertains to a medicator securing device for use in an I.V. administration in which a needle is inserted into a resilient cap member to add drugs and the like to an infusion procedure. This inserted needle is retained in inserted condition and position in this cap by this securing device. A flexible, substantially transparent plastic film having one surface coated with a self-stick adhesive is applied tightly to a frame of semi-rigid material. This frame provides at least one window-like opening which is covered by the adhesively-coated film. A release sheet member is applied to the window-like area until a time of use and application of the securing device, at which time the release sheet is removed and the adhesive surface of the film within said window is brought to and around the connection, with a fold made of the device so that the film is engaged tightly around the connection. At the time of removal, said frame portions are grasped to pull the adhesive surfaces of the film within the window-like area apart for removal or exposing of the connection. This device is also depicted as securing a Luer slip connection and being made with the frame and the window-like area protection of a same release-sheet material.

摘要： A liquid infusion catheter assembly comprises a hub and a first hollow catheter connected at its proximal end, and being in fluid communication with, the hub. This catheter has at least one fluid outlet opening. A second hollow catheter, extending from, but being out of fluid communication with, the hub surrounds the first catheter with a space therebetween. This second catheter extends distally farther than the first catheter and has at least one hole through its surface where it surrounds the first catheter, and has a fluid outlet opening in the portion extending beyond the first catheter.

摘要： A hub assembly for use in the filtration of fluids comprising a hub with a tapered bore extending therethrough, and a filter membrane in the bore. The filter membrane has a first portion extending across the bore and a second portion extending from the first portion in substantial contact with the hub around the bore. Means within the bore presses the second portion into tight contact with the hub around the bore to secure the filter membrane therein.A method of fabricating a filter membrane and inserting the same into a hub having a bore extending therethrough, the bore being substantially circular in cross section and tapered to define a large opening at its proximal end and a small opening at its distal end, includes forming a substantially flat, circular filter membrane from a filter medium, the membrane having a diameter larger than the large opening of the bore. The membrane is inserted into the tapered bore so that a first portion thereof is substantially perpendicular to the longitudinal axis of the bore, and as the membrane advances and the circular cross-section of the bore decreases, a second portion of the membrane is formed. This second portion is an annular flange extending from the first portion along the hub around the bore, and facing the large opening. The filter member is advanced a sufficient distance in the bore while pressing radially outwardly by a force against the flange so that the first portion is rendered taut by the wiping action of the flange along the hub. When the combination of the tapered bore and the force pressing against the flange provide a secure fit of the membrane within a predetermined location within the bore, the advance of the filter membrane therein is stopped.

摘要： The safety needle employs a manually operable actuator that can be depressed into a housing in order to release a spring-biased slider that carries a hollow needle. Upon release, the slider moves into a position to retract the needle over a blunt cannula so that the blunt cannula protects against cutting by the needle. An actuator guard may also be employed to prevent inadvertent actuation of the actuator.
