Blood alcohol monitor
DC CAFCFirst Claim
1. A portable monitor for sensing blood alcohol levels in a human subject comprising:
- alcohol measuring means for measuring a percentage of alcohol contained in a gas within a predetermined distance from the human subject'"'"'s skin to create a percentage measurement;
timer means for activating said alcohol measuring means at predetermined time intervals to cause aid alcohol measuring means to create a plurality of percentage measurements at said predetermined time intervals;
storage means for storing said plurality of percentage measurements;
securing means for portably and securely attaching said measuring means to the human subject;
detection means for detecting when said blood alcohol monitor is removed form the human subject; and
communication means for communicating said stored percentage measurements and detection results to a monitor station.

Abstract
A device which measures ethanol levels expelled through a subject'"'"'s skin to monitor blood alcohol level at regular or random intervals. The device differentiates between a positive reading caused by an external, interferant, source of ethanol and a positive reading caused by consumption of alcohol. The device is attached to the subject by a secure conductive strap which provides an indication that the device remains attached to the subject. The device monitors the skin temperature of the subject prior to performing the alcohol test to provide an indication of a barrier being placed between the device and the subject'"'"'s skin. The device measures the distance from the subject'"'"'s skin, thereby preventing the subject from moving the device far enough away to provide an inaccurate indication of the amount of alcohol in the subject'"'"'s blood and providing another tamper indication if the device is removed.

14. A method for monitoring the percentage of blood alcohol content of a human subject, said method comprising the steps of:
-
(a) securely attaching an alcohol measurement device to the human subject using an attachment device; (b) storing an error indication if the human subject tampers with said measurement device or an error occurs within said measurement device; (c) measuring a percentage of alcohol expelled through the subject'"'"'s skin into said measurement device and storing a measurement result; (d) repeating steps (b) and (c) until a predetermined amount of time expires; (e) transmitting each of said measurement results and each of said tamper and error indications to said monitoring station; and (f) repeating steps (b) through (e). - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
