Abstract
Abstract A device for implanting an object, such as a hormone pellet or an electronic transponder beneath the skin of an animal, includes a hollow needle (1) with an actuating rod (11) slidable therein, a cover (2) movable relative to the needle to enable at least the sharp end of the needle to be shrouded, and a locking mechanism in the form of an abutment (10) movable into a rebate (6), from which it cannot then return. The needle (11) may be mounted at one end of a body (4) which incorporates the locking rebate (6).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
242 words
A device for implanting or injecting an object beneath a skin of an animal, the device comprising: a body; a needle attached to said body and extending therefrom, said needle including a sharp end distal from said body which in use is inserted beneath the skin and from inside of which said sharp end the object is transferred to a position beneath the skin; a cover movably mounted on said body which is adapted to abut the skin of the animal in a retracted position after the sharp end of said needle is inserted beneath the skin and which is moveable on said body between the retracted position and an extended position in which the sharp end of the needle is covered by said cover as the needle is withdrawn from the skin; a rod attached to a part of said cover and projecting into said needle such that when the body is moved, relative to the cover which is held in contact with the skin, the cover is relatively moved between the retracted and extended positions and said rod acts to expel the object from the needle to the animal without affecting the position of the object beneath the skin; and a locking mechanism for permanently locking the cover against movement once said cover reaches the extended position to prevent the device from being used for more than one operation and to shroud at least said sharp end of the needle.
Claim 2
Independent Claim
242 words
A device for implanting or injecting an object beneath a skin of an animal, the device comprising: a body; a needle attached to said body and extending therefrom, said needle including a sharp end distal from said body which in use is inserted beneath the skin and from inside of which said sharp end the object is transferred to a position beneath the skin; a cover movably mounted on said body which is adapted to abut the skin of the animal in a retracted position after the sharp end of said needle is inserted beneath the skin and which is moveable on said body between the retracted position and an extended position in which the sharp end of the needle is covered by said cover as the needle is withdrawn from the skin; a rod attached to a part of said cover and projecting into said needle such that when the body is moved, relative to the cover which is held in contact with the skin, the cover is relatively moved between the retracted and extended positions and said rod acts to expel the object from the needle to the animal without affecting the position of the object beneath the skin; and a locking mechanism for permanently locking the cover against movement once said cover reaches the extended position to prevent the device from being used for more than one operation and to shroud at least said sharp end of the needle.
Claim 3
Dependent Claim
43 words
A device according to claim 1 in which said body includes an elongated track; in which said cover comprises an elongated sleeve and a spigot attached to said sleeve and projecting into said track; and wherein said rod is attached to said spigot.
Claim 4
Dependent Claim
46 words
A device according to claim 2 in which said locking mechanism comprises resiliently deformable abutment members on said spigot; and a rebate in said track into which said abutment members project when the cover reaches its extended position to lock said sleeve relative to said body.
Claim 5
Dependent Claim
71 words
A device according to claim 1 in which the locking mechanism includes a locking member which is operated automatically by moving the cover into the extended position, wherein operation of the device involves moving the cover from the retracted position to the extended position so as to always cause said locking member to be operated and thus to prevent the cover from being left inadvertently in the retracted position after use.
Claim 6
Dependent Claim
32 words
A device according to claim 1 and further comprising a handle whereby said handle is demountable as a separate component and a mounting formation on said body which interengages with said handle.
Claim 7
Dependent Claim
45 words
A device according to claim 1 wherein an end of said cover which abuts the skin in the retracted position is positioned from said sharp end of said needle by a predetermined distance equal to a desired insertion distance of said needle into the skin.
