Miniature wireless biomedical telemetry device

摘要

Provided herein are embodiments of a miniature wireless biomedical telemetry device along with systems and methods for its use. A miniature amplifier and transmitter allow recording of physiological signals from small animals, such as rats, mice and birds, as well as humans. The device is positioned externally and is easily replaceable, as is its battery, so surgical complications and other problem problems are minimized.

主权项

1. A wireless biomedical telemetry system comprising:
at least one detector for attachment to a living subject, the living subject movable in multiple directions relative to or on a substrate within a preselected volume, said at least one detector being configured to detect a signal generated by said living subject and to generate a detector signal reflective of the signals detected; and a telemetry device for attachment to and external to said living subject, said telemetry device including a power source and a wireless transmitter, said wireless transmitter being operably connected to said power source to receive power therefrom and to said at least one detector to receive said detector signal, and said wireless transmitter being configured to generate a modulated signal based on said detector signal; a transmitting antenna connected to said wireless transmitter for receiving the modulated signal, said transmitting antenna with said living subject and the free space in said volume configured to wirelessly transmit said modulated signal through said free space said transmitting antenna being movable with said living subject relative to or on said substrate; and a receiving antenna sized and fixedly positioned away from said living subject to effect a capacitive coupling with said transmitting antenna to receive through said free space said modulated signal therefrom; a receiver connected to said receiving antenna and configured to demodulate said modulated signal to form receiving signals reflective of the signals generated by said living subject; and a computer connected to said receiver configured to receive and selectively store data reflective of said signals generated by said living subject and display images reflective of said signals generated by said living subject.
