Abstract

Instruments and methods for performing non-invasive measurements of analyte concentrations and for monitoring, analyzing and regulating tissue status, such as tissue glucose levels.

Claims

1. A nocturnal glucose monitor, comprising:

a glucose measurement probe,

an alarm unit responsive to the glucose measurement probe, the alarm unit being operative to detect excursions of glucose values outside of a predetermined nocturnal glucose range for a diabetic patient and to produce an alarm signal in response to detected excursions, and

an audio transducer responsive to the alarm signal.

2. The nocturnal glucose monitor of claim 1 further including a remote transmitter responsive to the glucose measurement probe and a receiver responsive to the remote transmitter, wherein the audio transducer is responsive to the remote transmitter.

3. The nocturnal glucose monitor of claim 2 wherein the remote transmitter is a wireless transmitter and the receiver is a wireless receiver.
