A medicine injection pen includes a body, a drive member, a cartridge housing, and a medicine cartridge retained within the cartridge housing. The drive member is configured to move relative to the body and the medicine cartridge defines an interior volume configured to retain a liquid medicine. The drive member is configured to translate a piston within the interior volume toward a dispensing end of the medicine cartridge to dispense at least some of the liquid medicine. The medicine cartridge also includes an insertion port configured to receive a medicine dispensing element therethrough for dispensing a liquid medicine into the interior volume to replace at least some of the liquid medicine dispensed through the dispensing end. Dispensing of the liquid medicine into the interior volume of the medicine cartridge applies a fluid pressure to the piston to translate the piston away from the dispensing end of the medicine cartridge.

A liner associated with an adhesive skin patch of a physiological characteristic sensor includes a first end opposite a second end. The liner includes a first side opposite a second side. The liner includes a surface to couple to the adhesive skin patch, at least a portion of which extends from the first end to the second end. The liner includes at least one graspable member defined between the first side and the second side that extends beyond the first end or the second end to initiate a peel of the liner from the adhesive patch at a center of the liner.

Liner for adhesive skin patch

A system for a physiological characteristic sensor deployed with a sensor inserter includes an adhesive skin patch coupled to the physiological characteristic sensor. The adhesive patch is to couple the physiological characteristic sensor to an anatomy. The system also includes a gravity resistance system coupled to the adhesive patch and to be coupled to the sensor inserter. The gravity resistance system maintains the adhesive patch substantially perpendicular to a longitudinal axis of the sensor inserter prior to deployment of the physiological characteristic sensor and is removable from the adhesive patch by the sensor inserter upon deployment of the physiological characteristic sensor.

Removable devices wearable on a user's skin and methods for using such devices are provided. An exemplary removable device includes a skin adhesive configured to adhere to the skin, a durable component, and an interface component interconnecting the durable component and the skin adhesive. The device separates at the interface component to remove the durable component from the skin adhesive upon application of a removal force to the device.

Removable wearable device and related attachment methods

A sensor assembly for sensing a physiological characteristic of a user includes a power source, a power control switch, and a power latch within a housing. The power control switch is electrically coupled to the power source, and is configured to inhibit delivery of power from the power source to one or more components of the sensor assembly before deployment of the sensor assembly to a user, and deliver power from the power source to the one or more components of the sensor assembly in response to the deployment of the sensor assembly to the user. The power latch is configured to, upon the deployment of the sensor assembly to the user, latch an output of the power control switch to maintain the delivery of power from the power source to the one or more components of the sensor assembly while the sensor assembly is in a deployed state.

Energy management based on an open switch configuration

A medicine injection pen includes a body, a drive member within the body and configured to move relative thereto upon actuation, a cartridge housing releasably engageable with the body and configured to retain a medicine cartridge, at least one sensor, and at least one detector. The medicine cartridge has a liquid medicine therein and includes a piston configured to slide therein. The drive member is configured to move relative to the body to urge the piston to slide within the medicine cartridge to dispense at least some of the liquid medicine from the medicine cartridge. The sensor(s) is configured to sense movement of the drive member relative to the body to enable determination of an amount of the liquid medicine dispensed. The detector(s) is configured to detect a gap between the drive member and the piston.
