Abstract
A device, system, and method for measuring acetone levels exhaled from a patient and correlating the measured level to a blood glucose concentration.
Claims7
A device for measuring the concentration of acetone in exhaled air in order to determine the content of glucose in the blood, comprising:
- (a) an inlet configured for receiving expirated air;
- (b) a dosator configured for receiving air from said inlet;
- (c) an actuator configured for receiving air from said dosator with substantially the same volume for one or more measurements, said actuator interrupts air from said inlet when said dosator reaches a specified volume;
- (d) a chemical cell containing a solution and comprising a hollow truncated cone that is vertically orientated;
- (e) a light emitter constructed and arranged for emitting light of a frequency enabled to pass through said solution;
- (f) an optical sensor;
- and
- (g) a microprocessor;
- wherein said microprocessor produces an output correlating measurements of said optical sensor with blood glucose concentration.
