Patent ID: 8294588

Claim:
A wireless patient monitoring system for acquiring and wirelessly transmitting physiological data from a patient undergoing an MRI examination in an MRI machine, comprising: a housing; leads which acquire the physiological data from the patient during the MRI examination, the leads extending from the housing; an antenna which wirelessly transmits physiological data acquired from the patient during an MRI examination, the antenna supported by the housing; first and second interior portions defined within the housing, wherein the first interior portion is open to receive outside electrical interference including RF signals from the MRI machine and electrically isolated from the second interior portion; RF shielding which RF shields the second interior portion from RF signals from the MRI machine, a portion of the RF shielding extending between the first and second interior portions to RF shield the second interior portion from RF signals received via the first interior portion; circuitry disposed in the second interior portion, the circuitry including transmitter circuitry configured to transmit the physiological data wirelessly via the antenna to a remote base station; and a battery substantially free from ferromagnetic components and disposed in the first interior portion.
