MANUAL BASAL BOLUS DRUG DELIVERY DEVICE

摘要

A fully manually powered infusion device provides both basal and bolus delivery of a liquid medicament to a patient. In some embodiments, the device includes a main reservoir that supplies the liquid medicament, an outlet port that delivers the liquid medicament to the patient, a basal dispenser that delivers a substantially constant flow of the liquid medicament to the outlet port, and a manually actuated bolus pump that delivers a bolus dose of the liquid medicament from the main reservoir to the outlet when actuated. The basal dispenser delivers the substantially constant flow of the liquid medicament to the outlet port under energy stored as a direct result of and solely due to the manual actuation of the bolus pump. Also in some embodiments, the basal medicament supply delivers a volume of the liquid medicament from the main reservoir to the basal dispenser consonant with each actuation of the bolus pump.
