Abstract

The invention relates to a medicament injection device in which the material to be injected can be distributed through injection points over a large area surface, whereby simultaneously the device can be easily secured at the injection points and can lie relatively flush with the body without taking up a great deal of space. A mounting support is provided on which several cannulae are held spaced from one another, which are connected with a supply conduit and whose longitudinal axes, when the device is in a flat position, extend parallel to one another.

Claims

1. An injection device for the dispensation of medicaments comprising:

a hollow support and duct member having a longitudinal axis which is substantially parallel with an outer body-contacting surface containing orifices;

said hollow support and duct member being flexible for conforming to contours of the body of a user and lying against the contours;

said orifices having longitudinal axes which are transverse to the longitudinal axis of the support and duct member;

said orifices communicating with the duct of said member; and

cannulae communicating with said orifices.

2. An injection device according to claim 1, wherein there are more than two orifices and an equal number of cannulae.

3. An injection device according to claim 2, wherein the longitudinal axes of the cannulae do not all lie in the same plane.

4. An injection device according to claim 2, wherein the longitudinal axis of the support and duct member is nonrectilinear.

5. An injection device according to claim 2, wherein the support and duct member is arcuate.

6. An injection device according to claim 2, wherein the cannulae are substantially evenly spaced one from the other.

7. An injection device according to claim 2, wherein the support and duct member is ring-shaped and the cannulae are substantially evenly spaced.

8. An injection device according to claim 2, wherein at least one cannula is closed at the end remote from its corresponding orifice and such cannula contains at least one medicament-transporting duct transverse to its longitudinal axis.

9. An injection device according to claim 2, wherein the support and duct member is provided with a longitudinal connection for a medicament spigot.

10. An injection device according to claim 2, wherein the support and duct member has rigidity to support its own weight.

11. An injection device according to claim 2, wherein the support and duct member is ring-shaped and the longitudinal axis of the cannulae are substantially perpendicular to the longitudinal axis of the support and duct member.

12. An injection device according to claim 11, wherein at least one of the cannulae is closed at the end remote from its corresponding orifice and each such cannulae contains at least one medicament-transporting duct substantially perpendicular to the longitudinal axis of such cannula.

13. An injection device according to claim 11, wherein the support and duct member is tangentially connected to a spigot.

14. An injection device according to claim 11, wherein the orifices are substantially evenly spaced.

15. An injection device according to claim 12, wherein there are at least two medicament-transporting ducts.

16. An injection device according to claim 15, wherein the support and duct member is for affixing by affixing means to an area to receive an injection, the affixing means comprising physiological compatible cross-plaster bandages.

17. An injection device according to claim 16, wherein the support and duct member and the longitudinal connection are configured to have a low-profile.

18. An injection device for the substantially continuous dispensation of medicaments comprising:

a hollow support and duct member having a longitudinal axis which is substantially parallel with an outer body-contacting surface containing orifices;

said hollow support and duct member being flexible for conforming to contours of the body to lay against the contours;

said orifices having longitudinal axes which are transverse to the longitudinal axis of said support and duct member;

said orifices communicating with the duct of said support and duct member; and

cannulae communicating with said orifices.

19. The injection device according to claim 18, wherein said support and duct member is connected to means for substantially continuously dispensing medicaments.

20. The injection device according to claim 19, wherein:

said longitudinal axis of said support and duct member is nonrectilinear;

said support and duct member is arcuate;

there are more than two said orifices and an equal number of said cannulae;

said orifices are substantially evenly spaced along said support and duct member;

said cannulae are substantially evenly spaced from one another;

said support and duct member is ring-shaped;

at least one said cannulae is closed at the end remote from its corresponding orifice and such said cannulae contains at least one medicament-transporting duct transverse to its longitudinal axis;

said cannulae are substantially perpendicular to said longitudinal axis of said support and duct member;

said support and duct member is provided with a longitudinal connection for connection to said means for continuously dispensing medicament;

said support and duct member has rigidity to support its own weight;

said longitudinal connection is tangential with respect to said support and duct member;

there are at least two medicament transporting ducts;

said support and duct member is for affixing by affixing means to an area to receive an injection;

said affixing means comprises physiological compatible cross-plaster bandages; and

said support and duct member and said longitudinal connection are configured to have a low-profile.
