SYSTEM AND METHOD FOR SAVING BATTERY POWER IN A VITAL-SIGNS MONITOR
First Claim
1. A vital-signs patch in a patient monitoring system, the patch comprising a housing configured to be attached to the skin of a patient, the housing containing:
- monitoring circuitry configured to acquire and store measurements of vital signs of the patient;
a wireless transmitter configured to transmit signals to another device;
a wireless receiver configured to receive signals from the other device; and
a processor operably connected to the monitoring circuitry, transmitter, and receiver, configured to, upon receipt of an upload signal from the other device, send a message to the other device via the transmitter with a message packet structure comprising;
a data payload wherein the size of the data payload is variable;
a header containing transmit and route information and data payload length; and
a data integrity check value.

Abstract
A vital-signs device in a patient monitoring system is disclosed. The patch includes a housing configured to be attached to the skin of a patient. The housing contain monitoring circuitry configured to acquire and store measurements of vital signs of the patient, a wireless transmitter configured to transmit signals to another device, a wireless receiver configured to receive signals from the other device; and a processor operably connected to the monitoring circuitry, transmitter, and receiver. Upon receipt of an upload signal from the other device, the processor is configured to send a message to the other device via the transmitter. The message packet structure includes a data payload of variable size, a header containing transmit and route information and data payload length, and a data integrity check value.

14. A method of conserving battery power in a patch having vital-signs monitoring circuitry in a patient monitoring system, comprising the steps of:
-
receiving a transmit signal; retrieving vital-signs data; creating a message that contains; a data payload that contains at least a portion of the vital-signs data retrieved, wherein the size of the data payload is variable and may be zero; a header containing the information necessary to transmit and route the message, and the length of the data payload; and a data integrity check value that can be used with a defined message inspection protocol to verify that the message has been received intact; and transmitting the message.
