Summary for Patent: 9,981,087
Title:Automatic injection device
Abstract: Automatic injection device includes a housing, a syringe, a plunger, and a syringe carrier. The housing includes a barrel. The barrel includes an elongated window to allow viewing of contents inside the housing. The syringe is disposed within the housing and has a reservoir. The plunger is at least partially disposed within the syringe and includes a visual indicator. The syringe carrier is disposed within the housing and configured to contain the syringe and displace the syringe within the housing between a first position and a second position. The syringe carrier can have at least one opening and at least one pair of legs defining at least a portion of the at least one opening.

Application Number:14/673,463
Patent Claims:1. An automatic injection device comprising: a housing having a first end, a second end, and a barrel between the first end and the second end, the barrel comprising an elongated window to allow viewing of contents inside the housing; a syringe disposed within the housing and having a first end, a second end, and a reservoir between the first end and the second end; a plunger at least partially disposed within the syringe and comprising a visual indicator on a portion of the plunger; and a syringe carrier disposed within the housing and comprising: a substantially tubular body having a first end, a middle portion, and a second end, configured to contain a portion of the syringe and displace the syringe within the housing from a first position to a second position; a first pair of legs defining at least a portion of a first opening in the substantially tubular body, the first opening configured to align with the window and the reservoir when the syringe carrier is in the first position; and a syringe carrier coupler having a first beam and a second beam extending from the middle portion partially beyond the first pair of legs at the first end of the substantially tubular body.

2. The automatic injection device of claim 1, wherein the second end includes a second opening configured to align with the window and the visual indicator when the syringe carrier is in the second position.

3. The automatic injection device of claim 1, wherein the middle portion is sized to resist deformation of the syringe carrier.

4. The automatic injection device of claim 1, wherein the first pair of legs extends from the middle portion of the syringe carrier and each leg is tapered with a greater cross-dimension proximate the middle portion of the syringe carrier.

5. The automatic injection device of claim 1, wherein a portion of the first pair of legs is configured to engage at least one interior stop of the housing to prevent movement of the syringe carrier toward the second position.

6. The automatic injection device of claim 5, wherein each leg of the first pair of legs includes an anchor portion to engage the at least one interior stop to prevent movement of the syringe carrier toward the second position.

7. The automatic injection device of claim 6, wherein the anchor portion of each leg projects radially outwardly.

8. The automatic injection device of claim 6, wherein the anchor portion includes at least one projection sized to prevent movement of the syringe carrier away from the second position.

9. The automatic injection device of claim 6, wherein the anchor portion includes a first projection sized to prevent movement of the first projection past the at least one interior stop of the housing to prevent movement of the syringe carrier away from the second position, and a second projection sized to prevent movement of the syringe carrier toward the second position until the syringe carrier is urged in the direction of the second position to move the second projection past the at least one interior stop.

10. The automatic injection device of claim 9, wherein the first projection extends radially outward beyond the second projection.

11. The automatic injection device of claim 9, wherein the second projection comprises an arcuate surface portion and the interior stop comprises a chamfered edge portion configured to abut the arcuate surface portion when the syringe carrier is urged toward the second position.

12. The automatic injection device of claim 9, wherein a first force amount applied to the syringe carrier to move the second projection past the interior stop is less than a second force amount applied to the plunger to advance the plunger within the syringe.

13. The automatic injection device of claim 1, further comprising a second pair of legs defining at least a portion of a second opening diametrically opposite the first opening.

14. The automatic injection device of claim 1, wherein the first position is a pre-injection position and the second position is a post-injection position.

15. The automatic injection device of claim 1, wherein the syringe holds a liquid therapeutic agent.

16. The automatic injection device of claim 15, wherein the liquid therapeutic agent comprises a protein.

17. The automatic injection device of claim 15, wherein the liquid therapeutic agent comprises adalimumab.
