Abstract

An inserter for inserting a needle or cannula of an infusion set comprises a fixed inserter member and a movable inserter member movably connected to said fixed inserter member and adapted to receive the infusion set. The movable inserter member is movable from a first position to a second position to expose the needle or cannula. The movable inserter member is locked to the fixed inserter member in the first position to prevent accidentally exposing the needle or cannula.

Claims

1. An inserter for inserting a needle or cannula of an infusion set, comprising:

a fixed inserter member having a front wall, side walls, and a top wall, said walls forming a cavity, and a flexible beam connected to the front wall and extending rearwardly from the front wall of the cavity; and

a movable inserter member movably connected to said fixed inserter member and adapted to receive the infusion set, said movable inserter member being movable from a first position to a second position toward the cavity of the fixed inserter member to expose the needle or cannula, the movable inserter member being locked to the fixed inserter member in the first position to prevent accidentally exposing the needle or cannula, wherein

the flexible beam engages said movable inserter member to prevent movement of said movable inserter member from said first position to said second position.

3. The inserter according to claim 1, wherein

a latching arm of said movable inserter member is connected to said fixed inserter member to prevent separation of said movable inserter member from said fixed inserter member.

4. The inserter according to claim 1, wherein

the movable inserter member is only separatable from the received infusion set when the movable inserter member is in said second position.

5. The inserter according to claim 1, wherein

the inserter is removably connected to said infusion set.

6. The inserter according to claim 3, wherein

the latching arm includes a tab;

the fixed inserter member includes a shelf; and

in the first position, the tab engages the shelf to prevent the movable inserter member from being separated from the fixed inserter member.

10. The inserter according to claim 1, wherein the inserter is prevented from being removed from the infusion set until the needle is fully inserted.

2. An inserter for inserting a needle or cannula of an infusion set, comprising:

a fixed inserter member having a front wall, side walls, and a top wall, said walls forming a cavity, and a flexible beam that extends rearwardly from the front wall of the cavity; and

a movable inserter member movably connected to said fixed inserter member and adapted to receive the infusion set, said movable inserter member being movable from a first position to a second position to expose the needle or cannula, the movable inserter member being locked to the fixed inserter member in the first position to prevent accidentally exposing the needle or cannula, wherein

the flexible beam engages said movable inserter member to prevent movement of said movable inserter member from said first position to said second position; and

a flexible member of said movable inserter member is moved to deflect said flexible beam of said fixed inserter member, thereby disengaging from said fixed inserter member to allow movement of said movable inserter member from said first position to said second position.

7. The inserter according to claim 2, wherein

the movable inserter member includes ribs;

and

in the first position, the flexible beam engages the ribs to prevent accidental activation of the infusion set.

8. The inserter according to claim 2, wherein the flexible member is moved by squeezing the inserter together.

9. The inserter according to claim 2, wherein the flexible member is compressed inwardly to cause the flexible member to rotate about a living hinge, thereby unlocking the inserter.
