A physiological characteristic sensor system includes a physiological characteristic sensor. The physiological characteristic sensor includes a housing having a first housing portion coupled to a second housing portion, and an antenna coupled to the first housing portion. The physiological characteristic sensor system includes a sensor inserter configured to be coupled to the physiological characteristic sensor. The sensor inserter includes a sensor retainer, and the sensor retainer is configured to couple to the second housing portion in a second state to couple the physiological characteristic sensor to the sensor inserter.

Physiological characteristic sensor system

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.

Systems for wearable infusion port and associated pump

Fluid infusion systems such as a portable fluid infusion device includes a housing configured to accommodate a removable fluid reservoir. The housing has a largest dimension and a smallest dimension. The portable fluid infusion device includes a drive system configured to be serially coupled to the removable fluid reservoir such that a combined dimension of the drive system and the removable fluid reservoir is less than or equal to the largest dimension. The portable fluid infusion device includes a planar battery configured to supply power to the drive system. The planar battery has a plurality of faces comprising one or more faces having a largest area, and the planar battery being situated such that the one or more faces are parallel to the largest dimension and the smallest dimension.

Fluid infusion systems

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.

A pump clip for a fluid infusion device is provided. The pump clip includes a mount. The mount includes wings defined on opposed sides of the mount, a first lock tab to couple the pump clip to the fluid infusion device and a lip. The pump clip includes a base coupled to the mount that defines a second lock tab that engages with the lip to retain the mount in a first position. The mount is pivotable about a first pivot axis into a second position in which the mount is spaced apart from the base. The pump clip includes a clip coupled to the base, the clip pivotable about a second pivot axis relative to the base between a first, clamped position and a second, released position to receive an article.
