ABSTRACT:
In order to minimize the risk of infection when a large number of animals are injected with the same needle, an injecting gun is fitted with a sleeve which surrounds the needle. The sleeve comprises two telescoping tubes, and a detachable plastics cap incorporating a sponge impregnated with a sterilizing substance is fitted on the free end of the sleeve. The cap is provided with a twist off portion connected to the remainder of the cap by a thin-walled annular neck. The portion is separated from the remainder of the cap by twisting so as to form an aperture in the end wall of the cap, and an injection is then effected by applying the end of the cap to the proposed site of injection to cause the tubes to telescope so that the point of the needle moves through the sponge and passes through the aperture into the injection site.
