る。Therefore, in the present invention, in order to prevent the risk of infection by pathogenic bacteria, particularly when removing the injection needle, the needle is detached from the syringe body without using fingers and can be discarded. (FIG. 1) shows the central part of the present invention, in which the movable teeth 2 and the fixed teeth 3 are attracted to each other by the force of an elastic substance such as a spring 4 or rubber (FIG. 2). When the syringe is inserted as shown in (b) and the syringe is slid from (Fig. 2b) to (Fig. 2c), the thickness of the teeth increases according to the movement, and the needle falls naturally. It is.

Claims

(57) [Claims]

1. A hole of an appropriate size, such as a trapezoidal, oval or triangular shape, is formed in the vicinity of the center of a hard plate 1 and a movable tooth 2 and a fixed tooth 3 are formed at the hole. With the root of the tooth thicker and the tooth narrower with the narrower hole, the teeth with the narrower width are aligned with the abdomen of each tooth facing each other and in parallel, and further fixed The teeth 3 are adhered to the plate 1 and the movable teeth 2 are attached to the plate 1 so that the movable teeth 2 are rotatable about the thick roots of the movable teeth 2 around the shaft 5.
An injection needle detacher set so that the fixed teeth 3 and the movable teeth 2 are attracted to each other by a spring stopper (rubber stopper) 6 and a spring (rubber) 4 near a thick root.
