Abstract

A storage assembly is removably connectable to a drug delivery device. A first chamber is disposed in the housing. A plurality of penetrating members are stored in the first chamber. A second chamber is disposed in the housing for storing the plurality of penetrating members after being used in an injection. A transfer drum disposed in the housing transfers one of the penetrating members from the first chamber to an injection position and from the injection position to the second chamber following an injection.

Claims

1. A storage assembly, comprising:

a housing connectable to a drug delivery device;

a first chamber disposed in said housing;

a plurality of penetrating members stored in said first chamber;

a second chamber disposed in said housing for storing said plurality of penetrating members after being used in an injection; and

a transfer drum disposed in said housing for transferring one of said penetrating members from said first chamber to an injection position and from said injection position to said second chamber following an injection.

2. The storage assembly according to claim 1, comprising:

a drug delivery device connected to said housing as part of said combination.

3. The storage assembly according to claim 1, wherein

a drive gear having a protrusion is connected to the drug delivery device and a driven gear having a plurality of slots is connected to said transfer drum, such that rotation of said drive gear rotates said driven gear when said protrusion engages one of said plurality of slots.

4. The storage assembly according to claim 3, wherein

a stop member is engaged by said drive gear protrusion to stop further rotation of said drive gear when said penetrating member is in said second position.

5. The storage assembly according to claim 4, wherein

said stop member is manually released to allow further rotation of said drive gear.

6. The storage assembly according to claim 1, wherein

said transfer drum comprises a plurality of openings;

and

a transfer slide is movably disposed in each of said plurality of openings and is adapted to receive one of said penetrating members from said first chamber, said transfer slide being movable between a first position in which said penetrating member is within said housing and a second position in which said penetrating member extends from said housing drum to perform the injection.

7. The storage assembly according to claim 6, wherein

a spring biases said transfer slide to said first position.

8. The storage assembly according to claim 6, wherein

a rotary cam connected to said drive gear moves said transfer slide from said first position to said second position.

9. The storage assembly according to claim 6, wherein

a fluid connector disposed in said housing is in fluid communication with the drug delivery device, said fluid connector being in fluid communication with said penetrating member when said penetrating member is in said second position.

10. The storage assembly according to claim 9, wherein

a seal is formed around a connection between said fluid connector and said penetrating member when said penetrating member is in said second position.

11. A method of performing an injection with a drug delivery device, comprising the steps of:

transferring one of a plurality of penetrating members from a first chamber to a transfer drum by rotating the drug delivery device;

moving the transferred penetrating member to an injection position by continued rotation of the drug delivery device;

injecting a medicament from the drug delivery device through the transferred penetrating member into an injection site; and

transferring the used penetrating member to a second chamber.

12. The method of performing an injection with a drug delivery device according to claim 11, further comprising

preventing further rotation of the drug delivery device when the penetrating member is in the injection position.

13. The method of performing an injection with a drug delivery device according to claim 11, further comprising

discarding the second chamber of used penetrating members when all of the penetrating members stored in the first chamber have been used.

14. The method of performing an injection with a drug delivery device according to claim 13, wherein

preventing further rotation of the drug delivery device comprises engaging a drive gear connected to the drug delivery pen with a latch.

15. The method of performing an injection with a drug delivery device according to claim 14, further comprising

releasing the latch to perform another injection.
