Abstract

An indwelling needle assembly and a protector are provided. The indwelling needle assembly has an inner needle, an inner needle hub, an outer needle, an outer needle hub, and a protector for protecting the needle point of the inner needle arranged on the outer periphery of the inner needle so as to be slidable in the axial direction. The protector includes a protecting member in which the needle point of the inner needle is stored and a closing member arranged on the outer periphery of the protecting member so as to be capable of sliding, a displaceable side wall which is capable of being displaced inward so as to close a distal opening of the protecting member, the displaceable side wall being displaced inwardly by the closing member arranged on the outer periphery of the distal end portion of the protecting member.

Description

technical field [0001] The present invention relates to an indwelling needle assembly pierced and indwelling in a blood vessel when performing infusion or blood drawing, and a needle protector for protecting the needle point of the indwelling needle assembly, the needle body of an injection needle or similar needles. Background technique [0002] When infusion or blood drawing is performed on a patient, an indwelling needle is used. The indwelling needle includes: a metal needle body (inner needle body) for piercing the patient's skin and a metal needle body (inner needle body) arranged on the outer periphery of the inner needle body for indwelling in the patient's skin. Resin needle body (outer needle body) in blood vessel. The inner needle body of the indwelling needle has a sharp needle point, and after use, when the inner needle body is pulled out from the outer needle body and only the outer needle body is left in the patient's body, it may cause accidents such as wrong...
