Wireless patient monitoring system
First Claim
1. A device for monitoring a patient, comprising:
- a sensing device disposed at least one of on and in the patient and taking sensor data continuously;
a transmitter located on the exterior of the patient, internally powered, normally in a power-down state and powered-up for transmitting the sensor data, said transmitter comprising a first memory for temporarily storing sensor data;
a first link between the sensing device and the transmitter wherein the transmitter receives the sensor data from the sensing device and the first link comprises at least one of a wire and a wireless link;
a receiver, located remote from the patient, receiving the sensor data transmitted wirelessly from the transmitter and the transmission is at least one of a burst, and upon a command; and
wherein a confirmation signal is transmitted from the receiver to the transmitter to acknowledge receipt of the sensor data;
the confirmation signal instructs the transmitter to erase or overwrite the first memory temporarily storing the sensor data.

Abstract
A device and method for monitoring a patient having a sensing device taking sensor data continuously and a transmitter located on the patient and internally powered. The transmitter is normally in a power-down state and powered-up for transmitting the sensor data. A receiver is located remote from the patient and receives the sensor data transmitted wirelessly from the transmitter. The transmission is typically a burst and can also be initiated on a command. For the burst, the sensor data is accumulated over a first period. The transmitter can transmit the sensor data over a second period of time. The second period of time is shorter than the first period of time. Once the transmission is complete, transmitter can be powered down. A further step displays the sensor data at the receiver in pseudo real-time. The display is shifted by a sum of the first and the second period of time.

17. A method of monitoring a patient, comprising the steps of:
-
acquiring sensor data from a sensing device at least one of on and in the patient; linking the sensor data to a transmitter by at least one of continuously, at an interval and upon a command, said transmitter having a first memory; temporarily storing the sensor data in the first memory; powering the transmitter internally; locating the transmitter on the exterior of the patient; powering the transmitter down in a normal state; powering the transmitter up and transmitting the sensor data stored in the first memory from the transmitter to a receiver by at least one of a burst and upon command; receiving a confirmation signal sent from the receiver to the transmitter to acknowledge receipt of the sensor data; erasing or overwriting the sensor data stored in the first memory upon receipt of the confirmation signal; and disposing the receiver remote from the transmitter. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
