Abstract

An insertion device and insertion set. The insertion device for inserting at least a portion of at least one piercing member of an insertion set through the skin of a patient includes a device housing, a carrier body and a driver. The carrier body is slidably received within the device housing for movement between an advanced position and a retracted position. The carrier body also includes a receiving structure to support the insertion set in a position with the at least one piercing member oriented for insertion through the skin of the patient at a predetermined or variable angle relative to the skin of the patient upon movement of the carrier body from the retracted position to the advanced position. The driver is operatively coupled between the device housing and the carrier body to urge the carrier body from the retracted position toward the advanced position to place at least a portion of the at least one piercing member of the insertion set thorough the skin of the patient to install the insertion set to the patient. The receiving structure of the carrier body is removable from the insertion set while maintaining the installation of the insertion set to the patient.

Claims

1. A locking mechanism of an insertion device to insert an insertion set through the skin of a patient, comprising:

an arm coupled to a receiving end of a carrier body of the insertion device, wherein the carrier body is slidably received within a housing of the insertion device for movement between an advanced position and a retracted position; and

a securing structure coupled to the arm to secure the insertion set having at least one piercing member to the receiving end of the carrier body,

wherein the arm supports the insertion set in a position with the at least one piercing member of the insertion set oriented for insertion through the skin of the patient at a predetermined angle relative to the skin of the patient upon movement of the carrier body from the retracted position to the advanced position, and the securing structure is removable from the insertion set while maintaining installation of the insertion set to the patient.

2. The locking mechanism of claim 1, wherein the carrier body is shipped with the insertion set pre-installed.

3. The locking mechanism of claim 1, wherein the locking mechanism is secured in position by a spring member to facilitate locking and placement of the at least one piercing member of the insertion set at the predetermined angle relative to the skin of the patient.

4. The locking mechanism of claim 1, wherein the locking mechanism is secured in position by a hinged member to facilitate locking and placement of the at least one piercing member of the insertion set at the predetermined angle relative to the skin of the patient.

5. The locking mechanism of claim 1, wherein the locking mechanism is secured in position by a snap in place member to facilitate locking and placement of the at least one piercing member of the insertion set at the predetermined angle relative to the skin of the patient.

6. The locking mechanism of claim 1, wherein the locking mechanism is separate and removable from the carrier body.

7. The locking mechanism of claim 1, wherein the insertion device is adapted to permit insertion of different insertion sets using a corresponding separate and removable locking mechanism connected to the receiving end of the carrier body of the insertion device.

8. The locking mechanism of claim 1, wherein the securing structure is secured to at least a portion of a top side of the insertion set.

9. The locking mechanism of claim 1, wherein the insertion set further includes a cannula supported by the at least one piercing member of the insertion set to insert the cannula through the skin of the patient, and the at least one piercing member is retracted from the cannula after the insertion set has been placed on the patient.

10. The locking mechanism of claim 1, wherein the predetermined angle is about 90 degrees relative to the skin of the patient.

11. The locking mechanism of claim 1, wherein the predetermined angle is between 90 degrees and 10 degrees relative to the skin of the patient.

12. The locking mechanism of claim 1, wherein the predetermined angle is greater than 0 degrees and less than or equal to 10 degrees.

13. The locking mechanism of claim 1, wherein the insertion set is a transcutaneous insertion set.

14. The locking mechanism of claim 1, wherein the insertion set is a subcutaneous insertion set.

15. The locking mechanism of claim 1, wherein the insertion set rests mainly on the surface of the skin of the patient after insertion.

16. The locking mechanism of claim 1, wherein the insertion set is implanted in the skin of the patient.

17. The locking mechanism of claim 1, wherein the insertion set is adapted to adhere to the skin of the patient.

18. The locking mechanism of claim 1, further including infusion tubing coupled to the insertion set.

19. The locking mechanism of claim 1, wherein the at least one piercing member is a needle.

20. The locking mechanism of claim 1, wherein the at least one piercing member is a plurality of needles.

21. The locking mechanism of claim 1, wherein the at least one piercing member are micro-needles.

22. The locking mechanism of claim 1, wherein the insertion set is an infusion set.

23. The locking mechanism of claim 1, wherein the insertion set is a sensor set.

24. The locking mechanism of claim 1, wherein the insertion set is both an infusion set and a sensor set combined into an integral unit.
