Infusion pumps
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.
1. An infusion pump system, comprising:
a baseplate assembly comprising:
a baseplate;
a medicament cartridge on the baseplate defining a reservoir; and
a baseplate energy supply on the baseplate, the baseplate energy supply comprising a housing, an electrical energy storage device within the housing, and a pair of flexible electrical contacts respectively connected to an anode and a cathode of the electrical energy storage device, the baseplate energy supply configured to transfer energy to a replenishable energy supply of a reusable pump assembly when the baseplate assembly is coupled to the reusable pump assembly, the baseplate assembly being a disposable baseplate assembly;
a cannula; and
a cannula inserter.
2. The infusion pump system as claimed in claim 1 , wherein the cannula is located at least partially within the cannula inserter; and the cannula inserter is removably secured to the medicament cartridge.
3. The infusion pump system as claimed in claim 1 , further comprising:
a manifold;
wherein the cannula is located at least partially within the cannula inserter, and the cannula inserter is secured to the manifold.
4. The infusion pump system as claimed in claim 3 , wherein the manifold is attached to the medicament cartridge.
5. The infusion pump system as claimed in claim 1 , further comprising a plug configured to seal the medicament cartridge during a period of non-use.
6. The infusion pump system as claimed in claim 1 , wherein the baseplate comprises a pair of opposing connectors and a hook.
7. The infusion pump system as claimed in claim 6 , wherein the pair of opposing connectors and the hook are configured to attach the baseplate assembly to the reusable pump assembly.
8. The infusion pump system as claimed in claim 1 , wherein the pair of flexible electrical contacts is positioned to engage a plurality of receiving area contacts on a receiving area of the reusable pump assembly when the baseplate assembly is attached to the reusable pump assembly.
9. The infusion pump system as claimed in claim 1 , further comprising a seal that extends around a base of the housing.
10. The infusion pump system as claimed in claim 9 , wherein the seal is configured to engage a side wall of the receiving area of the reusable pump assembly when the baseplate assembly is attached to the reusable pump assembly.
11. A baseplate assembly comprising:
a baseplate that is separable from a pump assembly comprising a rechargeable battery; and
a battery carried on the baseplate, the battery comprising a housing, an electrical energy storage device within the housing, and a pair of flexible electrical contacts respectively connected to an anode and a cathode of the electrical energy storage device, the battery being configured to recharge the rechargeable battery when the baseplate assembly is coupled to the pump assembly.
12. A baseplate assembly, comprising:
a baseplate that is separable from a pump assembly comprising a replenishable energy supply; and
a baseplate energy supply on the baseplate, the baseplate energy supply comprising a housing, an electrical energy storage device within the housing, and a pair of flexible electrical contacts respectively connected to an anode and a cathode of the electrical energy storage device, the baseplate energy supply being configured to transfer energy to the replenishable energy supply of the pump assembly when the baseplate assembly is coupled to the pump assembly.
13. The baseplate assembly as claimed in claim 12 , wherein the pair of flexible electrical contacts is positioned to engage a plurality of receiving area contacts on a receiving area of a pump assembly when the baseplate assembly is attached to the pump assembly.
14. The baseplate assembly as claimed in claim 12 , further comprising a seal that extends around a base of the housing.
15. The baseplate assembly as claimed in claim 14 , wherein the seal is configured to engage a side wall of the receiving area of the pump assembly when the baseplate assembly is attached to the pump assembly.
