Abstract
A body-worn medication delivery pump having a patch form factor is provided that includes a controller and an integrated plethysmographic module that employs a photoplethysmographic multi-chip package disposed in a skin contact element designed to maintain contact with a wearer's skin during motion, reduce contact pressure inflammation during prolonged contact, reduce crosstalk and ingress of stray light, such that the controller of the pump programmed is programmed to adjust its medication delivery algorithms responsive to outputs of the plethysmographic module.
Claims20
A medication infusion device comprising:
- a flexible adhesive patch configured to be removably attached to a wearer's skin, the flexible adhesive patch having a periphery that defines an opening;
- a pump having a pump case with a lower surface configured to contact the periphery of the flexible adhesive patch, the lower surface including a bump configured to extend through the opening, the pump case configured to be removably coupled to the flexible adhesive patch to transcutaneously deliver doses of medication from a replaceable single-use cartridge disposed within the pump case to the wearer;
- and
- a photoplethysmographic module disposed within the bump, the photoplethysmographic module having an LED, a detector, and a skin contact element including at least one transparent window, wherein the LED emits light to, and the detector receives reflected light from, the wearer's skin through the at least one transparent window.
An insulin delivery device comprising:
- an adhesive patch configured to be removably attached to a wearer's skin, the adhesive patch having a periphery that defines an opening;
- a pump configured to be removably coupled to the adhesive patch to transcutaneously deliver insulin from an on-board replaceable single-use cartridge to the wearer, the pump having a pump case including a lower surface configured to adhere to the periphery of the adhesive patch, the lower surface including a protrusion that extends through the opening;
- and
- a plethysmographic module disposed within the protrusion, the plethysmographic module having an LED, a detector, and a skin contact element including at least one transparent window, wherein the LED emits light to, and the detector receives reflected light from, a skin surface of the wearer via the at least one transparent window.
