Embodiment Construction

[0035] see now figure 1 , which is a schematic diagram of a wearable bolus basal infusion device 10 embodying the present invention. In general, device 10 includes main reservoir 12 , outlet 14 , bolus pump 16 , basal dispenser 18 and basal drug supply 20 . Outlet 14 is fluidly coupled to cannula 22, which extends beneath the patient's skin 24 to deliver medication, such as insulin, to the patient. While device 10 and other devices embodying the invention may be shown schematically herein, such devices may be fully described by use of the aforementioned U.S. Physically constructed from the techniques and structures of patent application 12 / 147,283, which is owned by the assignee of the present application and is incorporated herein by reference in its entirety.

[0036] The bolus pump 16 is a piston pump that includes a chamber 30 and a piston 32 that forces the drug from the chamber 30 through a one-way valve 34 to the outlet 14 to deliver a bolus of drug to the patient. A...

Abstract

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.

Description

[0001] priority statement [0002] This patent application claims priority to U.S. Patent Application 13 / 360,485, filed January 27, 2012, which claims co-pending U.S. Provisional Patent Application Serial No. 61 / 444,121, filed February 17, 2011 rights and interests of the patent application, which is incorporated herein by reference in its entirety. Background technique [0003] The present invention relates to wearable infusion devices, and more particularly to such devices that enable patients to self-administer liquid medications conveniently and safely. The present invention more particularly relates to such wearable devices that provide bolus and basal drug delivery and are fully manually operable and actuated. One liquid drug that is often self-administered by patients is insulin, and for ease of description, the administration of insulin as generally used herein is for exemplary purposes, but the invention should not be limited to this exemplary use. [0004] Administ...
