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 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 and the baseplate can be separated from the infusion pump assembly without removing the plunger pusher from within the housing of the infusion pump assembly; and

wherein the plunger pusher is movable between a retracted position and an extended position where at least a portion of the plunger pusher is located within the medicament cartridge barrel.

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

3. An infusion pump system as claimed in claim 2, 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.

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

the baseplate assembly includes a cannula and a cannula inserter.

5. An infusion pump system as claimed in claim 4, 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.

6. A infusion pump system, comprising:

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

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;

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;

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.

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

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.

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

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

the baseplate assembly includes a cannula and a cannula inserter.

10. An infusion pump system as claimed in claim 9, 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.
