초록 ▼

This invention provides a protector for a sharpened tip of a needle of conventional construction. Preferably, foam rubber or plastic is used, with the rear of this foam material secured to the hub containing the needle and with the fore end of the foam material secured to a molded tubular guide end member. An inner sleeve is provided with the foam material. This foam material is shown as an extrusion or as a strip with adhesive on one side. This protector is accordionized when the needle is advanced into the patient. Bias may also be provided by a spring. The spring is shown as an integral part of a tubular length, with the interstice portions extending between convolutions of the spring. Three embodiments of spring placement are shown. In all embodiments, it is anticipated that the needle and protector will be brought to the patient, and with the needle advancement the protector accordionizes as the needle is inserted. The bias moves the end member to a tip-protecting condition and position as the needle is withdrawn.

대표청구항 ▼

A sharpened needle-tip protector for a conventional needle secured to and mounted in a hub which is adapted for mounting on the discharge end of a syringe, said tip protector adapted to be moved along a shank of said needle as the needle is inserted and advanced into a patient, the tip protector movable against a self-contained bias so that as the needle is withdrawn from the patient, the tip protector is urged by the bias to its original tip-protecting position whereby the sharpened tip of the needle is again covered so as to prevent accidental pricking of the attendant, said sharpened needle-tip protector including: (a) a front-end tubular guide member having an inner through passageway sized to be freely slideable on and along the shank portion of said sharpened needle; (b) said bias means is provided by an extrusion of foam material having an internal bore and an external configuration having a resiliency and a compressive capability of at least five to one, the foam being sufficiently dense so as to provide an inviolate barrier to external contamination; (c) said internal bore of the extrusion being arrayed over a determined length of thin flexible liner having a low coefficient of friction so as to provide a sliding surface adjacent the shank of the sharpened needle; (d) means for securing said protective member to that hub carrying and retaining said needle, and (e) said inviolate barrier extending between the needle hub and said front-end tubular member, this barrier maintaining exclusion of air during and until time of use.
