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.
Claims7
A system comprising:
- a wearable assembly comprising:
- a housing;
- 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 the housing;
- a control unit;
- and
- a transmitting and receiving base unit that powers the split ring resonator antenna, wherein the split ring resonator antenna is coupled to the transmitting and receiving base unit and whereby the split ring resonator antenna wirelessly transmits and receives data from the control unit, wherein the system minimizes parasitic effects of dielectric materials in close proximity to a wearable radio frequency device.
