Abstract

Apparatus for introducing a transponder in a living being wherein the transponder itself is outfitted with a sharpened member attached to the injection end of a transponder. The sharpened member comes in contact with the skin before the transponder thereby creating an opening in the skin such that the transponder can be blunt edged and move into the opening easily. The sharpened member is preferably constructed of a bio-compatible, preferably biodegradable material which may carry medication additionally.

Claims

1. Apparatus for injecting objects into a living being comprising:

an injector comprising a support housing and an injector tube having a selected inside diameter for receiving and guiding said objects being injected, said injector tube having a first end connected to and supported by said support housing and a further end extending away from said housing, said further end defining a blunt circumferential edge;

an elongated object to be injected and having a front end and a back end and a circumference able to be at least partially inserted into and supported by said injector tube, and

a tip member having a sharpened end and a rear portion wherein said rear portion has an outer circumference and an inner circumference cut from said rear portion and is secured to one end of said elongated object, said sharpened end suitable for penetrating the skin of said living being, and

wherein a transition area is provided between the rear portion of the tip member and the front end of the object to be injected, wherein the outer circumference of the tip member at its rear portion extends beyond the circumference of the front end of the object to be inserted and further, the front end of said object fits conformably within said inner circumference cut from said rear portion of said tip member.

2. Apparatus according to claim 1, wherein the injector tube is removable from the housing.

3. The apparatus according to claim 1, wherein said sharpened tip member is provided with at least two external ribs.

4. The apparatus according to claim 1, wherein said sharpened tip member comprises a material which is bio-compatible with the living being.

5. The apparatus according to claim 4, wherein the bio-compatible material comprises bone material.

6. The apparatus according to claim 4, wherein the biocompatible material comprises biodegradable material.

7. The apparatus according to claim 1, wherein said tip member contains a medication.

8. The apparatus according to claim 7, wherein the medication comprises a disinfectant.

9. The apparatus according to claim 1, wherein the transition area defines an abutment surface of said tip member through which a force can be applied from said support housing to said blunt circumferential edge of said injector tube to said abutment surface of said tip member so as to penetrate the skin of said living being.

10. The apparatus according to claim 1, wherein said elongated member is a transponder.

13. The apparatus of claim 4 wherein said liquid dosing means comprises a reservoir for containing a disinfectant, a pump, and a conduit connecting said injector tube, said pump and said reservoir.

11. Apparatus for injecting objects into a living being comprising:

an injector comprising a support housing and an injector tube having a selected inside diameter for receiving and guiding said objects being injected, said injector tube having a first end connected to and supported by said support housing and a further end extending away from said housing, said further end defining a blunt circumferential edge;

an elongated object to be injected and having a front end and a back end and a circumference able to be at least partially inserted into and supported by said injector tube, and

a tip member having a sharpened end a rear portion wherein said rear portion has an outer circumference and an inner circumference cut from said rear portion and is secured to one end of said elongated object wherein said elongated object fits conformably within said inner circumference, said sharpened end suitable for penetrating the skin of said living being, and

further comprising a liquid dosing means connected to said injector tube for providing a medicinal liquid to the penetrating site of the living animal.

12. The apparatus of claim 11, wherein said elongated object is a transponder.

14. Apparatus according to claim 11, wherein the injector tube is removable from the housing.

15. The apparatus according to claim 11, wherein said sharpened tip member is provided with at least two external ribs.

16. The apparatus according to claim 11, wherein said sharpened tip member comprises a material which is bio-compatible with the living being.

17. The apparatus according to claim 16, wherein the bio-compatible material comprises bone material.

18. The apparatus according to claim 16, wherein the bio-compatible material comprises biodegradable material.

19. The apparatus according to claim 11, wherein said tip member contains a medication.

20. The apparatus according to claim 19, wherein the medication comprises a disinfectant.
