Claims20
A portable ambulatory therapeutic fluid delivery device for delivering a therapeutic fluid in bolus doses into a body of a patient, the device comprising:
- at least one housing connectable to a cannula, the at least one housing including a reservoir for storing a therapeutic fluid;
- a mechanically powered pumping mechanism for delivering one or more bolus doses of the therapeutic fluid from the reservoir to the body of the patient through the cannula, wherein the pumping mechanism is configured to operate without using electrically-generated power;
- and
- a power-transfer mechanism for transferring manual power provided by a user to mechanically actuate the pumping mechanism, and
- wherein the at least one housing includes:
- a disposable part housing including at least a majority of the reservoir and an outlet port for enabling passage of the fluid to the body of the patient, and
- a reusable part housing removably attachable to the disposable part, the reusable part housing including at least a portion of the pumping mechanism and the power-transfer mechanism,
- wherein the delivery device is operable upon attachment of the reusable part housing and the disposable part housing, and
- wherein the reservoir is configured to be filled with the therapeutic fluid prior to attachment of the disposable part to the reusable part.
