ABSTRACT:
A device for insertion into a body cavity of an animal and for producing a controlled rate of release of chemicals into the body of the animal, has a spine with a body and legs hinged to the body, the spine being coated with a coating incorporating therein a material impregnated with one or more chemical impregnants which leach therefrom when exposed to body fluids, the legs being of a size foldable in a manner such that the cross sectional area and cross sections dimensions of the combined folded legs when in a folded position are substantially the same as the cross sectional area and dimensions of the body of the device.
An applicator is provided for inserting the device, the applicator having a shaft with a handle at one end and an open ended tube at the other end, the open ended tube having an open ended slot in the walls of said passageway with the open end of the slot at or near the open end of the tube and a discharging device comprising a rod having an operating member connected to the rod through a member which will enable the rod to be mounted within the open ended passageway with the operating member outside the tube so that on the device being fitted in a folded condition within the tube, the expelling device is operable to expel the device from the applicator after the applicator and device have been inserted in a body cavity of an animal.
