An automatic sensor inserter is disclosed for placing a transcutaneous sensor into the skin of a living body. According to aspects of the invention, characteristics of the insertion such as sensor insertion speed may be varied by a user. In some embodiments, insertion speed may be varied by changing an amount of drive spring compression. The amount of spring compression may be selected from a continuous range of settings and/or it may be selected from a finite number of discrete settings. Methods associated with the use of the automatic inserter are also covered.
1. A sensor insertion device, comprising: a shuttle movable between a first position and a second position, the shuttle configured to retain a transcutaneous sensor while in the first position and release the sensor while in the second position;a drive mechanism coupled to the shuttle to drive the s
1. A sensor insertion device, comprising: a shuttle movable between a first position and a second position, the shuttle configured to retain a transcutaneous sensor while in the first position and release the sensor while in the second position;a drive mechanism coupled to the shuttle to drive the shuttle from the first position to the second position based on a first driving force, wherein the drive mechanism includes a torsion spring configured to apply the first driving force;a retraction mechanism coupled to the shuttle to drive the shuttle from the second position to a neutral position based on a second driving force, wherein the retraction mechanism includes a compression spring configured to apply the second driving force, and wherein the neutral position is between the first position and the second position; anda control mechanism operatively coupled to the drive mechanism, wherein the control mechanism is configured to be manually operated by a user, and to cause the drive mechanism to release potential energy stored in the torsion spring and apply the first driving force to the shuttle. 2. The insertion device of claim 1, wherein the control mechanism is further configured to vary the first driving force over a continuous range of settings. 3. The insertion device of claim 1, wherein the control mechanism is configured to alternately set the first driving force to one of a plurality of discrete settings. 4. The insertion device of claim 1, wherein the control mechanism is solely mechanical. 5. The insertion device of claim 4, wherein the control mechanism includes a knob configured to be twisted by the user of the insertion device such that twisting of the knob varies the first driving force of the torsion spring. 6. The insertion device of claim 4, wherein the control mechanism includes a thumbwheel configured to be turned by the user of the insertion device such that turning of the thumbwheel varies the first driving force of the torsion spring. 7. The insertion device of claim 4, wherein the control mechanism includes a threaded rod. 8. The insertion device of claim 1, wherein the control mechanism includes a component configured to be set to one of a plurality of discrete, alternate shuttle orientations by the user of the insertion device, wherein each shuttle orientation varies the first driving force of the torsion spring. 9. The insertion device of claim 1, wherein the control mechanism includes a ratchet and lock mechanism. 10. A method of inserting a sensor, the method comprising: manually winding a control mechanism on an insertion device to vary a load on a torsion spring while maintaining a shuttle of the insertion device in a stationary position, wherein the control mechanism includes a ratchet and lock mechanism;placing the insertion device against a skin layer;firing a sensor into the skin layer using the control mechanism by releasing potential energy stored in the torsion spring;releasing the sensor from the shuttle of the insertion device; andretracting the shuttle of the insertion device to a location within the insertion device by releasing potential energy stored in a compression spring. 11. The method of claim 10, wherein manually winding the control mechanism on the insertion device is performed before placing the insertion device against the skin layer. 12. The method of claim 10, wherein firing the sensor into the skin layer using the control mechanism comprises depressing an actuator button. 13. The method of claim 12, further comprising manually deactivating a safety mechanism before depressing the actuator button. 14. The method of claim 10, wherein firing the sensor into the skin layer using the control mechanism further comprises displacing the control mechanism to one of a plurality of discrete settings. 15. The method of claim 10, wherein the control mechanism is solely mechanical. 16. The insertion device of claim 15, wherein the control mechanism includes a knob configured to be twisted by the user of the insertion device such that twisting of the knob varies the load on the torsion spring. 17. The insertion device of claim 15, wherein the control mechanism includes a thumbwheel configured to be turned by the user of the insertion device such that turning of the thumbwheel varies the load on the torsion spring. 18. The insertion device of claim 15, wherein the control mechanism includes a threaded rod.
