Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

Systems and methods for delivering microdoses of medication

A drug delivery device comprising a pumping system () and a liquid reservoir () fluidly connected to a delivery system outlet (), the liquid reservoir comprising an elastic plunger () scalingly slidable within a container wall () of the liquid reservoir for expelling liquid out of the reservoir. The pumping system comprises a piston pump () comprising a plunger actuator arranged to displace the plunger (), and a dosing unit () arranged downstream of the liquid reservoir () and fluidly connected to the liquid reservoir. The dosing unit () comprises a chamber portion () arranged between an inlet valve () and an outlet valve (), the chamber portion () arranged to receive from the liquid reservoir a pump cycle volume of liquid under an operational pressure greater than ambient pressure generated by the piston pump, and to the deliver said pump cycle volume of liquid to the delivery system outlet, said pump cycle volume being dependent on the operational pressure.

Patch pump device for drug delivery

Micropump () including a support structure (), a pump tube (), and an actuation system () comprising one or more pump chamber actuators (), the pump tube comprising a pump chamber portion () defining therein a pump chamber (), an inlet portion () for inflow of fluid into the pump chamber, and an outlet portion () for outflow of fluid from the pump chamber. The inlet, outlet and pump chamber portions form part of a continuous section of tube made of a supple material. The one or more pump chamber actuators are configured to bias against the pump chamber portion to expel liquid contained in the pump chamber via the outlet portion, respectively to bias away from the pump chamber portion to allow liquid to enter the pump chamber via the inlet portion. The pump chamber portion has a cross-sectional area Ap in an expanded state that is larger than a cross-sectional area Ai of the pump tube at the inlet and outlet portions.

Systems and methods for monitoring delivery of microdoses of medication

A body-worn medication delivery pump having a patch form factor is provided that includes an integrated plethysmographic module that employs a photoplethysmographic multi-chip package disposed in a frame designed to maintain contact with a wearer's skin during motion, and reduces cross-talk and ingress of stray light, a controller of the pump programmed to adjust its medication delivery algorithms responsive to outputs of the plethysmographic module.
