Abstract
Devices, systems and methods related to biopotential sensing and medical monitoring are disclosed. Biopotential sensor units include a transmitter for wirelessly transmitted the biopotential information. The transmitter may be limited by its transmission power and range in order to reduce electromagnetic interference. The biopotential sensors include an external auditory canal temperature sensor, an ear pulse oximeter, and a hypnotic state sensing EEG. The sensor units communicate with a patient monitor unit located on a patient. The patient monitor unit wirelessly communicates with a central station.
Claims17
A biosensor unit for sensing and transmitting human physiological information comprising:
- an ear canal temperature sensor for sensing temperature in a human;
- a transmitter electrically connected to the ear canal temperature sensor for receiving temperature information from the ear canal temperature sensor and transmitting the information across a distance;
- and
- the transmitter adapted to place information on the broadcast signal which identifies a type of biosensor.
A medical monitoring system, comprising:
- a plurality of sensor units, each sensor unit having a biosensor and a transmitter, the biosensor for sensing physiological data, the transmitter for transmitting the physiological data across a distance;
- at least one patient unit adapted to be located on or near a patient, the patient unit receiving the physiological data from the sensor units, interleaving the physiological data and transmitting the interleaved physiological data;
- and
- a monitor unit having a receiver to receive the interleaved physiological data transmitted from at least one patient, a display for displaying the physiological data, and adapted for receiving interleaved physiological data from at least one patient unit.
The medical monitoring system of 6 wherein at least one biosensor is an ear pulse oximeter.
A method of physiological monitoring comprising:
- sensing physiological conditions of a body through a plurality of sensors;
- wirelessly transmitting the physiological information from each sensor;
- receiving the physiological information from a plurality of sensors at a patient unit;
- interleaving the received physiological information at the patient unit;
- wirelessly transmitting the interleaved information by the patient unit;
- and
- receiving the interleaved information at a monitor unit.
