Abstract

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.
