Abstract
Devices and methods are disclosed for delivering multiple medicaments from multiple reservoirs to a patient. The devices and methods may be configured to prevent or reduce the incidence of a user transferring a fluid to or from an incorrect reservoir.
Claims23
An infusion pump system, comprising:
- a pump;
- a multi-reservoir cartridge system configured to be selectively attachable to and detachable from the pump, the multi-reservoir cartridge system comprising:
- a first fluid reservoir configured to contain a first medicament;
- and
- a second fluid reservoir configured to contain a second medicament;
- a first fluid reservoir interface configured to interface with the first fluid reservoir to facilitate delivery of the first medicament with the pump from the first fluid reservoir to a patient;
- and
- a second fluid reservoir interface configured to interface with the second fluid reservoir to facilitate delivery of the second medicament with the pump from the second fluid reservoir to the patient,
- wherein the first fluid reservoir interface and the second fluid reservoir interface are mechanically different from each other.
