System for monitoring physiological characteristics
First Claim
Patent Images
1. A device, comprising:
- a sensor input capable of receiving a signal from a sensor, the signal being based on a sensed physiological characteristic value of a user of the device, wherein the sensed physiological chatacteristic is a measurement of glucose; and
a processor coupled to the sensor input for operating an alarm based on the received signal from the sensor;
wherein the processor activates the alarm according to;
a first criteria when the user is awake; and
a second criteria when the user is asleep.

Abstract
Apparatuses and methods for medical monitoring physiological characteristic values such as blood glucose levels for the treatment of diabetes, are presented. The apparatuses and methods provide for preventing any negative consequence in the operation of a monitor and/or infusion device as a result of disorientation that may occur from waking from slumber with a low blood glucose level. In addition, a graphical display is disclosed incorporating a variety of enhancements which readily conveys to the user historical as well as real time information regarding the measured characteristic value.

15. A device, comprising:
-
a sensor input capable of receiving a signal from a sensor, the signal being based on a sensed physiological characteristic value of a user; and a processor coupled to the sensor input for operating an alarm based on the sensed physiological characteristic value of the user from the received signal from the sensor; wherein the processor activates the alarm and delays accepting input from the user when the alarm awakens the user. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A device, comprising:
-
a sensor input capable of receiving at least one signal from a sensor, the signal being based on a plurality of sensed physiological characteristic values of a user of the device; and a processor coupled to the sensor input for operating a plurality of alarms based on the received signal from the sensor, wherein; the processor is capable of activating each of the plurality of alarms according to a different sensed physiological characteristic value of the plurality of sensed physiological characteristic values; the plurality of sensed physiological characteristic values include; blood glucose concentrations in the user; and the rate of change of blood glucose concentrations in the user over a predetermined time period; a first alarm is activated when glucose concentrations exhibit a predetermined rate of change and a second alarm is activated when glucose concentrations reach a predetermined value; and the criteria for activating the first alarm are more stringent than the criteria for activating the second alarm. - View Dependent Claims (25, 26, 27)
