Abstract
An infusion pump assembly is disclosed. The infusion pump assembly includes a reservoir for receiving an infusible fluid, a pump assembly for pumping a quantity of infusible fluid from the reservoir to an exit, a first valve assembly configured to selectively isolate the pump assembly from the reservoir, a second valve assembly configured to selectively isolate the exit from the pumping assembly, and a split ring resonator antenna having a resonant frequency comprising a plurality of planar metallic layers.
Claims6
A wearable apparatus comprising:
- a split ring resonator antenna having a resonant frequency, the split ring resonator antenna comprising a plurality of planar metallic layers and defining a greatest dimension less than one wavelength at an operational frequency of 2.4 GHz ISM Band, the split ring resonator antenna located inside a housing;
- and
- an impedance matching circuit and wherein the wearable infusion pump apparatus minimizes parasitic effects of dielectric materials in close proximity to the wearable apparatus.
