    摘要： A pump for delivering a fluid includes a pump housing that defines at least one reservoir having a circumferentially open first end, a circumferentially closed second end and a chamber to receive the fluid. The pump includes a plunger assembly having at least one plunger arm and a cannula fluidly coupled to the plunger arm to dispense the fluid from the pump. The plunger arm is receivable within the first end of the reservoir, and the at least one plunger arm defining an internal conduit to receive the fluid from the at least one fluid reservoir. The internal conduit is fluidly coupled to the cannula. The plunger assembly is movable in a first direction relative to the pump housing to advance the plunger arm within the fluid reservoir to dispense the fluid from the fluid reservoir out of the pump via the cannula.

    摘要： A glucose sensor product maintains the sterility of the glucose sensor while allowing gaseous manufacturing by-products to be vented from the inside of the glucose sensor package. An exemplary glucose sensor product includes a plastic package tray and a glucose sensor assembly in the plastic package tray. The glucose sensor assembly includes an electrochemical sensor with glucose oxidase enzyme, a sensor base formed at least in part from plastic, a sensor mounting pedestal formed at least in part from plastic, and a sensor introducer formed at least in part from plastic. The glucose sensor product also includes a microbial barrier material coupled to the plastic package tray to seal the glucose sensor assembly in the plastic package tray. The microbial barrier material maintains sterility of the glucose sensor assembly while venting substances outgassed from the plastic package tray, the sensor base, the sensor mounting pedestal, and the sensor introducer.

    摘要： Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

    摘要： A wearable infusion port for infusing a fluid includes a first housing that defines an inlet port to receive the fluid, and a second housing coupled to the first housing. The second housing is to be coupled to an anatomy. The wearable infusion port includes a valve assembly fluidly coupled to the inlet port, and the valve assembly is movable from a closed state to an opened state to dispense the fluid. The wearable infusion port includes a cannula assembly extending through the first housing and the second housing, and the cannula assembly includes a cannula fluidly coupled to the valve assembly. The cannula is to be coupled to the anatomy. The wearable infusion port includes a flow sensor fluidly coupled to the inlet port and the cannula. The flow sensor is fluidly coupled upstream from the cannula to observe an amount of fluid received by the cannula.

    摘要： A pedestal for a physiological characteristic sensor assembly and a physiological characteristic sensor assembly is provided. The pedestal includes a first side opposite a second side. The pedestal includes a sidewall that interconnects the first side and the second side. The pedestal also includes a first end opposite a second end. The pedestal includes at least one post that extends from the first side adjacent to the first end to couple the pedestal to a physiological characteristic sensor of the physiological characteristic sensor assembly. The pedestal also includes a recess defined in the sidewall at the second end. The recess has a first portion in communication with a second portion. The first portion has a first length that is less than a second length of the second portion along a perimeter of the sidewall, and the second portion is positionable to apply a force to the physiological characteristic sensor.
