Abstract: The present invention relates to a subcutaneous needle in which a needle body and an adhesive tape are reliably secured together with a resin material enabling the operation to be correctly executed, and a method of producing the same. The subcutaneous needle is constituted by an adhesive tape, a separate paper, a needle body and a resin material. The adhesive tape has a hole formed in the central portion and has an adhesive surface on one side thereof. The separate paper has a hole in the central portion and is stuck on the adhesive surface of the adhesive tape. The needle body is bent in an L-shape and its top end side protrudes penetrating through the holes of the adhesive tape and of the separate paper. The base end side of the needle body is arranged nearly in parallel with a nonadhesive surface of the adhesive tape. The resin material is injection-molded onto the nonadhesive surface of the adhesive tape so as to cover and secure the base end side of the needle body.

Abstract: A device for preventing injury to the fingers of a person holding a cap into which an injector needle is inserted after use. The device is formed as a plate shaped member having a plane substantially transverse to the axis of the tube and having an area large enough to stop movement of the needle is not properly inserted into the cap when capping the injector. The plate member is provided with a thin-walled portion having a central opening and/or axial slits having inner edges which are elastically flexed and thus maintan a tight grip on the outer surface of the cap. Accordingly, the plate member is firmly fixed to the cap, and prevents injury to the fingers of a person holding the cap, by the needle, of the injector.
