Abstract

A system for inserting at least a portion of an insertion set through the surface of a tissue, having: an inserter with a moveable plunger disposed within a cavity therein; an insertion set holder received into the distal end of the cavity; and an insertion set received into the insertion set holder, wherein the insertion set is moveable within the insertion set holder such that when the plunger is advanced into contact with the insertion set, the insertion set advances through the insertion set holder to a position at which at least a portion of the insertion set extends out of the distal end of the cavity.

Claims

1. An inserter for inserting at least a portion of an insertion set through the surface of a tissue, comprising:

a housing having a cavity therein, wherein the distal end of the cavity is adapted to receive a holder for an insertion set therein, the holder being adapted for slidable motion of the insertion set therein; and

a moveable plunger disposed within the cavity for advancing the insertion set within the holder, wherein the plunger is moveable from a proximal position away from the insertion set to a distal position in contact with the insertion set.

2. The inserter of claim 1, wherein the holder is removable from the distal end of the cavity.

3. The inserter of claim 1, wherein the distal end of the cavity is adapted to receive the holder in a fixed position thereat.

12. The inserter of claim 1, wherein the inserter does not have a return spring.

4. A system for inserting at least a portion of an insertion set through the surface of a tissue, comprising:

an inserter with a moveable plunger disposed within a cavity therein; and

an insertion set holder received into the distal end of the cavity; and

an insertion set received into the insertion set holder, wherein the insertion set is moveable within the insertion set holder such that when the plunger is advanced into contact with the insertion set, the insertion set advances through the insertion set holder to a position at which at least a portion of the insertion set extends out of the distal end of the cavity.

5. The device of claim 4, wherein the moveable plunger is spring-loaded.

6. The system of claim 4, wherein the holder is removable from the distal end of the cavity.

7. The device of claim 4, wherein the holder is held at a fixed position in the distal end of the cavity.

8. The system of claim 4, wherein the plunger is moveable from a proximal position away from the insertion set to a distal position in contact with the insertion set.

9. An insertion set, comprising:

a housing;

a piercing member extending from the housing; and

a holder, wherein the housing is slidably moveable within the holder from a first position at which a portion of the housing extends out of the holder and the piercing member does not extend out of the holder to a second position at which the piercing member extends out of the holder.

10. The system of claim 9, wherein the insertion set further comprises:

infusion tubing extending from the housing.

13. The insertion set of claim 9, wherein the housing holds the insertion set such that the piercing member of the insertion set is at an angle of between 10 and 90 degrees to the skin.

11. A holder for an insertion set, the insertion set having a housing with a piercing member extending therefrom, the holder being dimensioned such that the housing is slidably moveable within the holder from a first position at which a portion of the housing extends out of the holder and the piercing member does not extend out of the holder to a second position at which the piercing member extends out of the holder.
