Abstract

An injection apparatus for injecting a medicament into a patient, the injection apparatus has a stationary head and a movable head that is movable with respect to the stationary head. A needle is attached to a needle holder that is held by the movable head and by the stationary head. When the movable head is urged rearwardly, a front edge of the needle moves forwardly with respect to a front face of the movable head.

Claims

1. An injection apparatus for injecting a medicament into a patient, the injection apparatus comprises:

a body comprising a stationary head and a movable head that is movable with respect to the stationary head, and

a needle attached to a needle holder, the needle holder being held by the movable head and by the stationary head, wherein;

urging the movable head rearwardly moves a front edge of the needle forwardly with respect to a front face of the movable head, and wherein;

the movable head comprises a movable slot,

the stationary head comprises a stationary slot, and

the movable slot is inclined at a crossing angle with respect to the stationary slot.

2. The injection apparatus according to claim 1, wherein the movable head is axially movable with respect to the stationary head.

3. The injection apparatus according to claim 1, wherein the crossing angle is in the range of 70°

to 110°

.

4. The injection apparatus according to claim 1, wherein the movable slot is straight.

5. The injection apparatus according to claim 1, wherein the stationary slot is concave with respect to an imaginary center of curvature of the stationary slot that is located forwardly to the stationary slot.

6. The injection apparatus according to claim 1, wherein the needle holder comprises an elongated leading pin, the leading pin passes through the stationary slot and through the movable slot, and wherein:

rearward movement of the movable head with respect to the stationary head urges a forward movement of the leading pin with respect to the movable slot and a rearward movement of the leading pin with respect to the stationary slot.

7. The injection apparatus according to claim 6, wherein the injection apparatus comprises a pair of stationary slots, a pair of movable slots, and a pair of leading pins, and wherein:

the stationary slots, the movable slots and the leading pins are symmetrical with respect to a median plane of the injection apparatus.

8. The injection apparatus according to claim 6, wherein the leading pin has a leading pin length that is larger than a leading pin width, and wherein:

the leading pin length is similar to a stationary slot width and slightly smaller therefrom, and, the leading pin width is similar to a movable slot width and slightly smaller therefrom.

9. The injection apparatus according to claim 1, wherein the injection apparatus comprises a handle for being held by an operator.

10. The injection apparatus according to claim 1, wherein the movement of the needle from a retracted position, in an unpressed position of the movable head, to a fully extended position, in a fully pressed position of the movable head, is along a straight line and at a predetermined slant angle with respect to a longitudinal axis of the injection apparatus.

11. The injection apparatus according to claim 10, wherein the slant angle is in the range of 0°

to 70°

.

12. The injection apparatus according to claim 1, wherein the medicament is injected automatically when the needle has reached a predetermined fully extended position.

13. The injection apparatus according to claim 1, wherein the injection apparatus comprises a dosing chamber, and a piston for pushing the medicament out of the dosing chamber, and wherein the medicament is loaded automatically into the dosing chamber right after the piston had reached a piston forwardmost position.

14. The injection apparatus according to claim 1, wherein the injection apparatus comprises a control panel for administrating and displaying various functions of an injection process, and the control panel transmits a real-time information to another device.

15. The injection apparatus according to claim 1, further comprising means for setting and verifying different volumes of a dose to be injected.

16. The injection apparatus according to claim 1, further comprising at least 2 inlet non-return valves, wherein each inlet is connected to a different medicament container.

17. The injection apparatus according to claim 16, wherein each one of said inlet non-return valves opens and closes electronically.

18. The injection apparatus according to claim 17, wherein said inlet non-return valves are controlled by a microprocessor.

19. The injection apparatus according to claim 1, wherein the needle being used is a curved needle.

20. The injection apparatus according to claim 1, wherein the needle is curved and the notch which leads the needle is also curved such that when the needle comes out of the movable head, the needle enters underneath the animal skin without penetrating deeply into the animal muscle or tissue.
