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. An infusion system for pumping a fluid into a body of a user, the infusion system comprising:

an infusion pump, wherein the infusion pump comprises an infusion pump housing including a cavity;

a fluid storage 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 removably connected to the fluid storage.

2. The infusion system of claim 1, further comprising a cap for holding the fluid storage in place inside the infusion pump housing.

3. The infusion system of claim 1 wherein:

the adapter comprises an adapter housing comprising a hollow interior and a connection that connects the adapter to the infusion set;

a cannula positioned inside the cartridge; and

the adapter is attached to the cartridge.

4. The infusion system of claim 3, wherein the hollow interior comprises a spring or a shock absorbing material disposed between the adapter housing and the infusion pump housing.

5. The infusion system of claim 3, wherein the adapter housing comprises a first part disposed within the cavity and a second part connected to the cartridge wherein, the adapter housing is formed by connecting the second part to the first part, and the second part comprises the cannula.

6. The infusion system of claim 5, wherein the first part comprises a spring or a shock absorbing material disposed between the adapter housing and pump housing.

7. The infusion system of claim 3, wherein the adapter further comprises a valve disposed between the connection and the cannula such that the valve prevents free flow of the fluid.

8. The infusion system of claim 1, wherein the adapter comprises a torque transfer mechanism that transfers torque from the adapter to the cartridge.

9. The infusion system of claim 8, wherein the torque transfer mechanism comprises a plurality of ribs in the adapter.

10. An infusion system for pumping a fluid into a body of a user, the infusion system comprising:

an infusion pump housing;

a cavity disposed within the infusion pump housing;

a cartridge; and

an adapter comprising a connection and a cannula wherein, the adapter encases and is connected to the cartridge, the cannula is inside the cartridge, and the adapter connects into the cavity.

11. The infusion system of claim 10 further comprising a cap holding the cartridge and the adapter in place inside the infusion pump housing and an infusion set removably connected to the connection.

12. The infusion system of claim 10, wherein the adapter comprises a spring or a shock absorbing material disposed between an adapter housing and the infusion pump housing.

13. The infusion system of claim 10, wherein the adapter comprises a first part disposed within the infusion pump housing and a second part attached to the cartridge wherein, the adapter is formed by coupling the second part to the first part, and the second part comprises the connection and the cannula.

14. The infusion system of claim 13, wherein the first part comprises a spring or a shock absorbing material disposed between an adapter housing and the infusion pump housing.

15. The infusion system of claim 10, wherein the adapter further comprises a valve disposed between the connection and the cannula such that the valve prevents free flow of the fluid.

16. The infusion system of claim 10, wherein the adapter comprises a torque transfer mechanism that transfers torque from the adapter to the cartridge.

17. The infusion system of claim 16, wherein the torque transfer mechanism comprises a plurality of ribs in the adapter.

18. A method of providing an infusion system for pumping a fluid into a body of a user, the infusion system having an infusion pump housing with a cavity, the method comprising:

placing a cartridge into the cavity of the infusion pump housing;

connecting an adapter comprising a connection and a cannula to the cartridge such that the adapter encases the cartridge; and

inserting the cannula into the cartridge when the adapter is connected to the cartridge.

19. The method of claim 18, further comprising coupling a first part of the adapter to a second part of the adapter wherein, the first part of the adapter is disposed inside the cavity of the infusion pump housing and the second part comprises the cannula and the connection, and is connected to the cartridge.
