摘要:
Current castration methods cause concern on animal welfare grounds as a degree of pain is experienced by the animal during the castration process. This pain could be minimised by using anaesthetic, however anaesthetic is not typically provided as it is difficult to administer. The invention solves this problem by providing an injector having a two stage injection that allows for anaesthetised castration procedures to be efficiently performed. The injector comprises: an outer housing having a first end and a second end; and a plunger assembly for being received within the outer housing and comprising a barrel having a needle disposed at an end thereof and a plunger for dispensing a fluid through the needle; in use the plunger assembly being movable within the outer housing between a retracted position wherein the needle is at least partially housed within the outer housing and an engaged position wherein the needle projects outwardly of a needle opening located at the first end of the outer housing and whereby a rotary inhibiting mechanism interacts with the plunger assembly to inhibit movement of the plunger within the barrel until the plunger assembly has reached the engaged position.
