Abstract

Infusion systems for pumping fluid into a body of a user, and methods for providing infusion systems, are disclosed. The infusion systems include an infusion pump, wherein the infusion pump comprises an infusion pump housing including a cavity. A fluid storage is removably inserted into the cavity of the infusion pump housing wherein, the fluid storage comprises a cartridge and an adapter connected to the cartridge such that the adapter encases the cartridge, and an infusion set is removably connected to the fluid storage.

Claims

1. A monolithic adapter for receiving cartridges of differing sizes for pumping fluid into a body, the monolithic adapter comprising:

a monolithic adapter housing comprising a first end and a second end, the adapter housing

comprising a hollow interior such that at least one of the cartridges can be removably received in the hollow interior through the first end of the adapter housing and fully encased within the adapter housing; and

a cannula that pierces a septum of the at least one of the cartridges when the adapter encases the at least one of the cartridges;

wherein the adapter housing comprises a spring or a shock absorbing material within the hollow interior of the adapter housing such that when the at least one of the cartridges is moved into the adapter housing toward the second end of the adapter housing, the at least one of the cartridges snaps into the adapter housing, the monolithic adapter being configured to receive the cartridges of differing sizes such that each snap fits within the adapter housing.

2. The method of claim 1 wherein the monolithic adapter comprises the shock absorbing material within the hollow interior of the monolithic adapter housing.

3. The monolithic adapter of claim 1 wherein the adapter housing comprises at least one of grooves, ridges, and recesses for the snap fit of the at least one of the cartridges.

4. The monolithic adapter of claim 1 wherein the at least one of the cartridges is coupled to the first end and the second end of the adapter housing.

5. The monolithic adapter of claim 1 wherein the adapter housing comprises a cylindrical shape, and the shape of the adapter housing is compatible with the outer shape of a housing of the at least one of the cartridges.

6. The monolithic adapter of claim 1 wherein the monolithic adapter comprises the shock absorbing material disposed within the hollow interior and the shock absorbing material disposed between the monolithic adapter and an infusion pump housing to which the monolithic adapter is couplable.

7. The monolithic adapter of claim 1 further comprising a torque transfer mechanism that transfers torque from the adapter to the at least one of the cartridges, the torque transfer mechanism comprising a plurality of ribs equally spaced in the hollow interior of the in the adapter housing.

8. The monolithic adapter of claim 1 wherein the plurality of ribs comprises three ribs.

9. The monolithic adapter of claim 1 wherein the adapter housing comprises two longitudinal slits extending from the first end toward the second end.

10. The monolithic adapter of claim 1 wherein the monolithic adapter comprises the spring within the hollow interior of the monolithic adapter housing.

11. The monolithic adapter of claim 1 wherein the cartridge is a pen cartridge.

12. A method of using a monolithic adapter for receiving multiple cartridge sizes for pumping fluid into a body, comprising:

providing a monolithic adapter housing comprising a first end and a second end, the adapter housing comprising a hollow interior such that at least one of the cartridges can be removably received in the hollow interior through the first end of the adapter housing and fully encased within the adapter housing; and

a cannula that pierces a septum of the at least one of the cartridges when the adapter encases the at least one of the cartridges;

wherein the adapter housing comprises a spring or a shock absorbing material within the hollow interior of the adapter housing such that when the at least one of the cartridges is moved into the adapter housing toward the second end of the adapter housing, the at least one of the cartridges snaps into the adapter housing, the monolithic adapter being configured to receive the cartridges of differing sizes such that each snap fits within the adapter housing; and

inserting the at least one of the cartridges through the first end of the adapter housing which is open, sliding the adapter fully over the at least one of the cartridges such that the adapter housing engages and covers the at least one of the cartridges and such that the cannula pierces the septum of the at least one of the cartridges; and

inserting the adapter and the at least one of the cartridges as a unit into an infusion pump.

13. The method of claim 12 further comprising pumping fluid into the body.

14. The method of claim 12 wherein the fluid comprises insulin.

15. The method of claim 12 further comprising remotely controlling the pumping of the fluid using a remote control device.

16. The method of claim 15 wherein the remote control device comprises a mobile device.

17. The method of claim 15 wherein the remote control device comprises a smart phone or a personal data assistant.

18. The method of claim 12 further comprising refilling the at least one of the cartridges.

19. The method of claim 12 further comprising removing the adapter and the at least one of the cartridges and inserting a new fluid storage into the infusion pump.

20. The method of claim 19 wherein the new fluid storage system comprises the adapter and at least a second of the cartridges, wherein the at least one of the cartridges and the at least the second of the cartridges are different in size.
