Abstract

An insertion device for use with an insertion set is provided. The insertion device includes a first housing having a rail. The insertion device includes a hub having a first end coupled to the rail and a second end including a projection. The hub is movable relative to the first housing along the rail. The insertion device includes a locking carrier in the first housing and movable between a first position and a second position. The locking carrier is coupled to the projection in the first position and the projection is released in the second position. The insertion device includes a second housing coupled to the insertion set and surrounding at least a portion of the first housing to define a gap. The locking carrier is received in the gap in the second position to release the projection of the hub and to enable the insertion set to be uncoupled.

Claims

1. An insertion device for use with an insertion set, comprising:

a first housing having a rail that extends within the first housing along a longitudinal axis of the insertion device;

a hub having a first end coupled to the rail and a second end to be coupled to an insertion instrument, the hub movable relative to the first housing along the rail and the second end including a projection;

a locking carrier received in the first housing and movable relative to the first housing between a first position and a second position, the locking carrier coupled to the projection in the first position and the projection is released from the locking carrier in the second position; and

a second housing coupled to the insertion set and surrounding at least a portion of the first housing to define a gap between the first housing and the second housing, with the locking carrier received in the gap in the second position to release the projection of the hub from the locking carrier and to enable the insertion set to be uncoupled from the second housing.

2. The insertion device of claim 1, wherein the first housing has a first housing end and a second housing end, the rail coupled to the first housing end and the rail is spaced apart from the second housing end.

3. The insertion device of claim 2, further comprising a biasing member coupled to the first housing between an inner surface of the first housing at the first housing end and the locking carrier, and the biasing member substantially surrounds the rail.

4. The insertion device of claim 3, wherein the locking carrier has a first carrier end and an opposite second carrier end, the first carrier end coupled to the biasing member and the insertion device further comprises a trigger that contacts the second carrier end to hold the locking carrier in the first position.

5. The insertion device of claim 2, wherein the rail includes a shaped end that cooperates with the first end of the hub to couple the hub to the rail.

6. The insertion device of claim 1, wherein the locking carrier has a central bore that receives the projection in the first position, the central bore having a first bore diameter in the first position, and the central bore has a second bore diameter in the second position that is different than the first bore diameter.

7. The insertion device of claim 1, wherein the second housing includes at least one locking arm that couples the insertion set to the insertion device, and the at least one locking arm pivots into engagement with the first housing to uncouple the insertion set from the second housing in the second position.

8. An insertion device for use with an insertion set, comprising:

a first housing having a rail that extends within the first housing along a longitudinal axis of the insertion device;

a hub having a first end coupled to the rail and a second end to be coupled to an insertion instrument, the hub movable relative to the first housing along the rail and the second end including a projection;

a locking carrier received in the first housing and movable relative to the first housing between a first position and a second position, the locking carrier having a central bore coupled to the projection in the first position and the projection is released from the central bore of the locking carrier in the second position; and

a second housing having at least one locking arm coupled to the insertion set and the second housing surrounding at least a portion of the first housing to define a gap between the first housing and the second housing, with the locking carrier received in the gap in the second position to release the projection of the hub from the locking carrier and to pivot the at least one locking arm to enable the insertion set to be uncoupled from the second housing.

9. The insertion device of claim 8, wherein the first housing has a first housing end and a second housing end, the rail coupled to the first housing end and the rail is spaced apart from the second housing end.

10. The insertion device of claim 9, further comprising a biasing member coupled to the first housing between an inner surface of the first housing at the first housing end and the locking carrier.

11. The insertion device of claim 10, wherein the locking carrier has a first carrier end and an opposite second carrier end, the first carrier end coupled to the biasing member and the insertion device further comprises a trigger that contacts the second carrier end to hold the locking carrier in the first position.

12. The insertion device of claim 9, wherein the rail includes a shaped end that cooperates with the first end of the hub to couple the hub to the rail.

13. The insertion device of claim 8, wherein the central bore has a first bore diameter in the first position, and the central bore has a second bore diameter in the second position that is different than the first bore diameter.

14. The insertion device of claim 8, wherein the at least one locking arm pivots into engagement with the first housing to uncouple the insertion set from the second housing in the second position.

15. An insertion device for use with an insertion set, comprising:

a first housing having a rail that extends within the first housing along a longitudinal axis of the insertion device;

a hub having a first end coupled to the rail and a second end to be coupled to an insertion instrument, the hub movable relative to the first housing along the rail and the second end including a projection;

a locking carrier received in the first housing and movable relative to the first housing between a first position and a second position, the locking carrier having a central bore coupled to the projection in the first position and the projection is released from the central bore of the locking carrier in the second position, the central bore having a first bore diameter in the first position and a second bore diameter in the second position that is different than the first bore diameter; and

a second housing coupled to the insertion set and the second housing surrounding at least a portion of the first housing to define a gap between the first housing and the second housing, with the locking carrier received in the gap in the second position to release the projection of the hub from the locking carrier and to enable the insertion set to be uncoupled from the second housing.

16. The insertion device of claim 15, wherein the first housing has a first housing end and a second housing end, the rail coupled to the first housing end and the rail is spaced apart from the second housing end.

17. The insertion device of claim 16, further comprising a biasing member coupled to the first housing between an inner surface of the first housing at the first housing end and the locking carrier, and the biasing member substantially surrounds the rail.

18. The insertion device of claim 17, wherein the locking carrier has a first carrier end and an opposite second carrier end, the first carrier end coupled to the biasing member and the insertion device further comprises a trigger that contacts the second carrier end to hold the locking carrier in the first position.

19. The insertion device of claim 16, wherein the rail includes a shaped end that cooperates with the first end of the hub to couple the hub to the rail.

20. The insertion device of claim 15, wherein the second housing includes at least one locking arm that couples the insertion set to the insertion device, and the at least one locking arm pivots into engagement with the first housing to uncouple the insertion set from the second housing in the second position.
