Abstract

Apparatuses and methods for medical monitoring physiological characteristics values such as blood glucose levels for the treatment of diabetes, are presented. The apparatuses and methods provide dynamic glucose monitoring functions that perform predictive analysis to anticipate harmful conditions, such as glucose crash and hyperglycemic incidents for a patient. The dynamic functions can also be used to maximize athletic performance and warn of inadequate nocturnal basal rate. Other aspects include advanced alarm and reminder functions, as well as advanced data presentation tools to further facilitate convenient and efficient management of various physiological conditions.

Claims

1-86. -86. (canceled)

87. A physiological characteristic monitor, comprising:

an input device capable of receiving a signal from a sensor, the signal being based on a physiological characteristic value of a user; and

a processor for analyzing the received signal and determining physiological characteristic value data of the user from the received signal;

a memory for storing the physiological characteristic value data of the user; and

a display for providing a retrospective display of the physiological characteristic value data.

88. The physiological characteristic monitor of claim 87, wherein the stored physiological characteristic value data includes a minimum and maximum blood glucose value and the retrospective display shows the minimum and maximum blood glucose value with a respective time and date.

89. The physiological characteristic monitor of claim 87, wherein the stored physiological characteristic value data includes a first number of excursions above an upper blood glucose value and a second number of excursions below a lower blood glucose value and the retrospective display shows the first and second number.

90. The physiological characteristic monitor of claim 87, wherein the stored physiological characteristic value data includes a distribution of blood glucose values and the retrospective display shows a first portion of the blood glucose values above an upper blood glucose value, a second portion of the blood glucose values below a lower blood glucose value and a third portion of the blood glucose values between the upper value and the lower value.

91. The physiological characteristic monitor of claim 90, wherein the first, second and third portions are shown as percentages.

92. The physiological characteristic monitor of claim 90, wherein the first, second and third portions are shown as times.

93. The physiological characteristic monitor of claim 90, wherein the first, second and third portions are shown as numbers of readings.

94. The physiological characteristic monitor of claim 90, wherein the display includes a total time for the physiological characteristic value data.

95. The physiological characteristic monitor of claim 90, wherein the display includes a total number of readings for the physiological characteristic value data.

96. The physiological characteristic monitor of claim 90, wherein the first portion and the second portion are shown as integrated values.

97. The physiological characteristic monitor of claim 96, wherein the integrated values are based on the sums of magnitude differences from the upper blood glucose value and the lower blood glucose value for the first and second portion, respectively.

98. The physiological characteristic monitor of claim 96, wherein integrated values are divided by a respective duration of sensor use.

99. A method of displaying physiological characteristic value data, comprising the steps of:

receiving a signal from a sensor, the signal being based on a physiological characteristic value of a user; and

analyzing the received signal and determining physiological characteristic value data of the user from the received signal;

storing the physiological characteristic value data of the user; and

showing a retrospective display of the physiological characteristic value data.

100. The method of claim 99, wherein the stored physiological characteristic value data includes a minimum and maximum blood glucose value and the retrospective display shows the minimum and maximum blood glucose value with a respective time and date.

101. The method of claim 99, wherein the stored physiological characteristic value data includes a first number of excursions above an upper blood glucose value and a second number of excursions below a lower blood glucose value and the retrospective display shows the first and second number.

102. The method of claim 99, wherein the stored physiological characteristic value data includes a distribution of blood glucose values and the retrospective display shows a first portion of the blood glucose values above an upper blood glucose value, a second portion of the blood glucose values below a lower blood glucose value and a third portion of the blood glucose values between the upper value and the lower value.

103. The method of claim 102, wherein the first, second and third portions are shown as percentages.

104. The method of claim 102, wherein the first, second and third portions are shown as times.

105. The method of claim 102, wherein the first, second and third portions are shown as numbers of readings.

106. The method of claim 102, wherein the display includes a total time for the physiological characteristic value data.

107. The method of claim 102, wherein the display includes a total number of readings for the physiological characteristic value data.

108. The method of claim 102, wherein the first portion and the second portion are shown as integrated values.

109. The method of claim 108, wherein the integrated values are based on the sums of magnitude differences from the upper blood glucose value and the lower blood glucose value for the first and second portion, respectively.

110. The method of claim 108, wherein integrated values are divided by a respective duration of sensor use.
