Abstract

Ambulatory infusion pumps, pump assemblies, and baseplate assemblies, including cartridges, baseplates, cannulas, inserters, and related components and batteries therefor, as well as component combinations and related methods.

Claims

1. An infusion pump system, comprising:

an infusion pump assembly including a housing and a rechargeable battery within the housing; and

a baseplate assembly including a baseplate and a baseplate energy supply;

wherein the infusion pump assembly and the baseplate assembly are configured to be attached to one another in such a manner that energy from the baseplate energy supply is transferred to the rechargeable battery.

2. An infusion pump system as claimed in claim 1, wherein

the infusion pump housing includes a recess configured to receive the baseplate energy supply;

the baseplate energy supply projects outwardly from the baseplate; and

the infusion pump housing recess and baseplate energy supply are respectively positioned such that the baseplate energy supply will be located at least partially within the pump housing recess when the infusion pump assembly and the baseplate assembly are attached to one another.

3. An infusion pump system as claimed in claim 1, wherein

the baseplate energy supply includes energy supply electrical contacts;

the infusion pump assembly includes pump assembly electrical contacts; and

the baseplate energy supply electrical contacts and pump assembly electrical contacts are respectively positioned such that the baseplate energy supply electrical contacts will contact the pump assembly electrical contacts when the infusion pump assembly and the baseplate assembly are attached to one another.

4. An infusion pump system as claimed in claim 1, wherein

the rechargeable battery has a rechargeable battery voltage;

the baseplate energy supply has a baseplate energy supply voltage; and

the infusion pump assembly includes a DC-to-DC converter adapted to convert the baseplate energy supply voltage to a voltage that is greater than the rechargeable battery voltage.

5. An infusion pump system as claimed in claim 1, wherein

the baseplate energy supply includes a baseplate battery.

6. An infusion pump system as claimed in claim 1, wherein

the baseplate battery comprises a primary cell battery.

7. An infusion pump system as claimed in claim 1, wherein

the infusion pump assembly includes a pump module that drives fluid from a reservoir.

8. An infusion pump system as claimed in claim 7, further comprising:

a cartridge that includes the reservoir.

9. An infusion pump system as claimed in claim 8, wherein

the cartridge is secured to the baseplate.

10. A infusion pump system as claimed in claim 1, further comprising:

a medicament reservoir;

a temperature sensor positioned to sense a temperature of or approximating that of medicament in the medicament reservoir; and

a controller configured to modulate recharging of the rechargeable battery as a function of temperature sensed by the temperature sensor.

11. An infusion pump system as claimed in claim 1, wherein

the baseplate assembly includes a cannula and a cannula inserter.

12. An infusion pump system as claimed in claim 11, wherein

the baseplate assembly includes a medicament cartridge with a reservoir and a through-bore in fluid communication with the reservoir;

and

the cannula is configured to fit within the through-bore.

13. A method, comprising the step of:

securing a baseplate assembly with a baseplate energy supply to an infusion pump assembly with a rechargeable battery such that energy from the baseplate energy supply is transferred to the rechargeable battery.

14. A method as claimed in claim 13, wherein

the baseplate assembly includes a medicament cartridge;

and

the step of securing comprises securing the baseplate assembly to the infusion pump assembly such that the medicament cartridge is inserted into the infusion pump assembly and energy from the baseplate energy supply is transferred to the rechargeable battery.

15. A method as claimed in claim 13, wherein

the baseplate energy supply includes an energy storage device.

16. A method as claimed in claim 13, wherein

the energy storage device comprises a primary cell battery.

17. An infusion pump system, comprising:

an infusion pump assembly including a housing and a plunger pusher within the housing; and

a baseplate assembly including a baseplate and a medicament cartridge, including a barrel defining a reservoir and a plunger movable within the barrel, on the baseplate;

wherein the infusion pump assembly and the baseplate assembly are configured to be attached to one another in such a manner that the plunger pusher will be aligned with the plunger.

18. An infusion pump system as claimed in claim 17, wherein

the infusion pump assembly includes a rechargeable battery;

the baseplate assembly includes a baseplate energy supply; and

the infusion pump assembly and the baseplate assembly are configured to be attached to one another in such a manner that energy from the baseplate energy supply is transferred to the rechargeable battery.

19. An infusion pump system as claimed in claim 18, wherein

the infusion pump housing includes a recess configured to receive the baseplate energy supply;

the baseplate energy supply projects outwardly from the baseplate; and

the infusion pump housing recess and baseplate energy supply are respectively positioned such that the baseplate energy supply will be located at least partially within the pump housing recess when the infusion pump assembly and the baseplate assembly are attached to one another.

20. An infusion pump system as claimed in claim 17, wherein

the baseplate assembly includes a cannula and a cannula inserter.

21. An infusion pump system as claimed in claim 20, wherein

the medicament cartridge includes a through-bore in fluid communication with the reservoir;

and

the cannula is configured to fit within the through-bore.

22. A infusion pump system as claimed in claim 17, further comprising:

a temperature sensor positioned to sense a temperature of or approximating that of medicament in the reservoir when the baseplate assembly is attached to the housing; and

a controller configured to modulate recharging of the rechargeable battery as a function of temperature sensed by the temperature sensor.

23. A baseplate assembly, comprising:

a baseplate;

a medicament cartridge on the baseplate defining a reservoir;

a cannula; and

a cannula inserter.

24. A baseplate assembly as claimed in claim 23, further comprising:

a baseplate energy supply on the baseplate.

25. An infusion pump system as claimed in claim 23, wherein

the cannula is located at least partially within the cannula inserter;

and
