Device, system, and method for patient activity monitoring

摘要

A portable telemetry device includes a physiological component, a movement component, a wireless radio, and a communication component. The physiological component is configured to receive, from at least one sensor, physiological data representative of a physiological condition of a patient. The movement component is configured to detect movement of the portable telemetry device and generate movement data. The portable telemetry device is configured to attach to the patient. The wireless radio is configured to wirelessly send radio signals. The communication component is configured to transmit the physiological data and the movement data to a monitoring system using the wireless radio.

1. A portable telemetry device comprising:
a physiological component configured to receive, from at least one sensor, physiological data representative of a physiological condition of a patient; a movement component configured to detect multi-axis accelerations of the portable telemetry device and generate movement data, including multi-axis acceleration data, wherein the portable telemetry device is configured to attach to the patient; an activity component configured to distinguish between and identify each of a plurality of patient movement activities by:
comparing a time-varying acceleration waveform pattern of the multi-axis acceleration data for a first time period with predetermined acceleration patterns to identify a first activity of the patient,identifying a transition movement by the patient from the first activity to a second activity based on a comparison of the time-varying acceleration waveform pattern with the predetermined acceleration patterns during a second time period,comparing a time-varying acceleration waveform pattern of the multi-axis acceleration data for a third time period with the predetermined acceleration patterns to identify the second activity of the patient; a wireless radio configured to wirelessly send radio signals; and a communication component configured to transmit a patient alert to a third party monitoring system with the physiological data and the movement data using the wireless radio, the patient alert including:
an identification and duration of the first activity of the patient,identification of the transition movement to the second activity, andidentification of the second activity of the patient.
