Abstract

Claims (25)

1. An insertion device for installation of a medical device having a transcutaneous element, the insertion device comprising:

a device holder for holding the medical device,

an installation surface configured to contact the medical device so as to deploy the—transcutaneous element of the medical device;

an elastic installation element configured to apply a force to the installation surface so as to bring the installation surface into contact with the medical device;

a tensioner configured to move towards or away from the medical device to adjust the force applied by the elastic installation element to the installation surface, wherein at least a portion of the tensioner is in direct contact with the elastic installation element, and

a button, wherein pressing the button for a first time is configured to cause ne elastic installation element to apply the force to the installation surface, and wherein pressing the button a second time is configured to cause release of the medical device from the device holder.

2. The insertion device of claim 1 , wherein the installation surface is connected to one or more latches configured to be brought into mating contact with one or more corresponding recesses in a surface of an internal casing surrounding the elastic installation element, wherein, when the one or more latches are in mating contact with the one or more corresponding recesses, the elastic installation element is in a compressed state, wherein the button is connected to extension elements, and wherein pressing the button is configured to cause the extension elements to contact the one or more latches and to release the mating contact between the one or more latches and the one or more corresponding recesses.

3. The insertion device of claim 1 , wherein the button is connected to a first rotation surface and wherein the installation surface is connected to a second rotation surface, and wherein the second press of the button is configured to cause the first rotation surface to move toward and to engage with the second rotation surface so as to cause rotation of the second rotation surface from an original rotation position, thereby causing rotation of the device holder so as to release the medical device from the device holder.

4. The insertion device of claim 3 , wherein the device holder comprises an angled slot configured to apply a release force to the medical device held in the device holder when the device holder is rotated.

5. The insertion device of claim 3 , further comprising a return element configured to return the second rotation surface to the original rotational position after the first rotation surface is brought out of contact with the second rotation surface.

6. The insertion device of claim 1 , wherein the insertion device further comprises a rotating dial connected to the tensioner, the rotating dial configured to adjust a position of the tensioner, and wherein adjusting the position of the tensioner is configured to cause the adjustment of the force applied by the elastic installation element to the installation surface.

7. The insertion device of claim 1 , wherein a tension indicator is connected to the tensioner, wherein the tension indicator is configured to provide a visual indication of the force applied by the elastic installation element to the installation surface.

8. The insertion device of claim 7 , wherein the tension indicator is provided in a slot of an outer casing of the insertion device.

9. The insertion device of claim 1 , wherein the device holder is configured to hold an infusion set comprising a cannula.

10. The insertion device of claim 1 , wherein the device holder is configured to hold an analyte sensor comprising a sensor probe.

11. A method of using an insertion device to install a medical device, the method comprising:

inserting a medical device having a transcutaneous element into a device holder of the insertion device;

positioning the device holder against an installation site;

pressing a button of the insertion device for a first time to install the transcutaneous element of the medical device; and

pressing the button of the insertion device for a second time to release the medical device from the insertion device.

12. The method of claim 11 , further comprising adjusting a force used to install the transcutaneous element of the medical device.

13. The method of claim 12 , wherein the step of adjusting a force used to install the transcutaneous element of the medical device comprises rotating a dial of the insertion device.

14. The method of claim 13 , wherein the step of rotating the dial causes movement of a tension indicator to provide a visual indication of the force used to install the transcutaneous element.

15. The method of claim 11 , wherein the medical device comprises an infusion set and the transcutaneous element comprises a cannula.

16. The method of claim 11 , wherein the medical device comprises an analyte sensor and the transcutaneous element comprises a sensor probe.
