Abstract:
1. A remotely-monitored liquid infusion apparatus, comprising: a liquid conduit; a pump disposed within a housing to receive the liquid conduit and to transfer a liquid from a liquid source through the liquid conduit in response to activation of the pump; a wireless radio wave transceiver disposed within an RF-shielded portion of the housing; a sensor configured to provide physiological monitoring of at least one of a heart beat, respiration and blood pressure, wherein the wireless radio wave transceiver is configured to wirelessly transmit, to a remote, high-priority data comprising information corresponding to the occurrence of a physiological event and low-priority data comprising information corresponding to operation of the liquid infusion apparatus, wherein the wireless radio wave transceiver receives, from the remote, data used to control operation of the pump, wherein the data used to control operation of the pump is provided to a pump controller disposed within the RF-shielded portion of the housing, wherein the wireless radio wave transceiver is configured to transmit the low-priority data in packets that are scheduled to be transmitted in substantially sequential order and to transmit the high-priority data in packets that are scheduled to be transmitted shortly after the occurrence of a physiological event, wherein transmission of the high-priority data may temporarily interrupt the substantially sequential transmission of the low-priority data, wherein the RF-shielded portion is configured to pass higher frequency RF signals used for wireless communication while attenuating image-interfering RF signals having a frequency under about 130 MHz, and further wherein the wireless radio wave transceiver is in communication with an antenna mounted outside the RF-shielded portion of the housing.
