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 proximal end, a distal end, and a plurality of bellows located between the proximal end and the distal end, the compressible body defining an inner cavity for holding a liquid medicant, the distal end of the compressible body including an annular locking protrusion configured to engage one or more of the bellows at the distal end of the compressible body to enable priming of the device;
a tip positioned at the proximal end of the compressible body; and
an outer luer body positioned around an external surface of the tip and engaged with the tip, the tip and the outer luer body form a first fitting.

2. The medicant injection device of claim 1 , wherein the outer luer body includes internal threading.

3. The medicant injection device of claim 1 , wherein the tip is integrally formed with the compressible body.

4. The medicant injection device of claim 1 , wherein the outer luer body engages the tip with a snap fit to form the first fitting, and wherein the first fitting is a first luer fitting.

5. The medicant injection device of claim 4 , wherein the tip includes an external shoulder and the outer luer body includes an internal annular ridge, the internal annular ridge being configured to engage the external shoulder to connect the outer luer body with the tip.

6. The medicant injection device of claim 1 , further comprising a housing positioned at the distal end of the compressible body, the housing defining a chamber configured to receive an antiseptic cap.

7. The medicant injection device of claim 1 , the compressible body further comprising a male locking tab and a female locking tab, wherein the male locking tab is configured to engage the female locking tab to lock the compressible body in a compressed position.

8. The medicant injection device of claim 1 , further comprising a removable tab configured to prevent liquid medicant from being expelled from the tip.

9. The medicant injection device of claim 8 , further comprising a breakable interface configured to secure the removable tab to the outer luer body.

10. The medicant injection device of claim 8 , further comprising a breakable interface configured to secure the removable tab to the tip.

11. The medicant injection device of claim 8 , wherein the removable tab provides a visual display informing a user if the medicant injection device has been used.

12. The medicant injection device of claim 1 , wherein the one or more of the bellows at the distal end comprises a non-uniform walled locking bellow.

13. The medicant injection device of claim 1 , wherein the tip includes a first geometry and the outer luer body includes a second geometry, the first and second geometry mating to prevent rotation of the outer luer body with respect to the tip.

14. The medicant injection device of claim 1 , further comprising external graduation markings on the compressible body.

15. The medicant injection device of claim 1 , further comprising a valve configured to control fluid flow.

16. The medicant injection device of claim 1 , wherein the compressible body is prefilled with the liquid medicant.

17. The medicant injection device of claim 1 , the annular locking protrusion being configured to engage one or more of the bellows at a position inside the inner cavity.

18. The medicant injection device of claim 1 , wherein the annular locking protrusion is configured to engage the one or more of the bellows at the distal end upon priming of the device.

19. The medicant injection device of claim 18 , wherein the annular locking protrusion is configured to prevent the one or more bellows at the distal end from disengaging with the annular locking mechanism after priming of the device.
