Abstract

A medicant injection device includes a compressible body, a tip, and an outer luer body. The compressible body has a proximal end, a distal end, and a plurality of bellows, and defines an inner cavity for holding a liquid medicant. The tip is positioned at the proximal end of the compressible body. The outer luer body includes internal threads, and is positioned over and engaged with the tip to form a first fitting therewith. The first fitting is configured to be connected with a second fitting. A medicant injection device includes a compressible body having first and second arms, a receptacle interconnected with the compressible body and defining an inner cavity, and a first fitting configured to engage a second fitting. The compressible body is configured to be compressed by forcing the distal end of the first and second arm toward each other.

First claim

What is claimed is:

1. A medicant injection device, comprising:
a compressible body including a first arm and a second arm, wherein the first and second arms are connected at a base region of the compressible body and are spaced apart at a compressible region opposite the base region, the compressible body further including a first fitting integrally formed with the first and second arms at the base region; and
a receptacle interconnected with the compressible body and defining an inner cavity for holding a liquid medicant;
wherein at least one of the first arm and the second arm is at least partially disposed within the receptacle, and wherein the compressible body is configured to be compressed by forcing the first and second arms, proximate the compressible region, toward each other such that the liquid medicant contained in the receptacle is ejected from the first fitting when the compressible body is compressed.

2. The medicant injection device of claim 1 wherein the first arm has first free end portion at the compressible region and the second arm has a second free end portion at the compressible region, the second free end portion movable into and out of engagement with the first free end portion.

3. The medicant injection device of claim 2 wherein at least one of the first free end portion and the second free end portion is within the receptacle, first a proximal end and a first distal end, and the second arm has a proximal end and a distal end.

4. The medicant injection device of claim 1 wherein the first arm and the second arm are entirely disposed within the receptacle.

5. The medicant injection device of claim 1 wherein the receptacle is secured to an exterior surface of the compressible body.

6. The medicant injection device of claim 5 wherein the receptacle is secured to the exterior surface proximate the base region.

7. The medicant injection device of claim 1 wherein the first arm includes a locking feature for securing to the second arm.

8. The medicant injection device of claim 1 wherein the first arm includes a locking ridge and the second arm includes a locking loop, the locking ridge and the locking loop configured to engage each other and lock the compressible body in a compressed position.

9. The medicant injection device of claim 1 further comprising a ratchet mechanism provided between the first arm and the second arm to enable air priming.

10. The medicant injection device of claim 1 wherein a first portion of a proximal end of the first arm connects with a first portion of a proximal end of the second arm to form a first region of a proximal base, and a second portion of the proximal end of the first arm connects with a second portion of the proximal end of the second arm to form a second region of the proximal base.

11. The medicant injection device of claim 10 wherein the first fitting is connected to the first and second regions of the proximal base.

12. The medicant injection device of claim 10 wherein the first fitting is positioned between the first and second regions of the proximal base.

13. The medicant injection device of claim 10 wherein at least one of the first region of the proximal base and the second region of the proximal base includes a tapered portion that extends to the first fitting.

14. The medicant injection device of claim 1 wherein a proximal end of the first arm has a cutout region which does not connect to a proximal end of the second arm, the cutout region extending through a planar portion of the first arm.

15. The medicant injection device of claim 1 wherein the first and second arms are plates each having an inner face and an outer face, and wherein at least a portion of the inner face is configured to engage the receptacle when the compressible body is compressed.

16. The medicant injection device of claim 1 wherein the first arm includes at least one longitudinal rib extending along an exterior surface of the first arm.
