ABSTRACT:
Measurements of insulin quantities in a syringe are performed optically in an integrated insulin dose recorder/blood glucose meter. The syringe is placed in a holder before and after the administration of the dose. Liquid quantities in the syringe are determined by comparing optical response patterns of the syringe with calibration data stored in the device. Dose histories are downloaded to a patient computer for transfer to a clinician's computer. Standard or customized syringes (e.g. with marked plungers) may be used. Other wave energy carriers such as sound waves may also be used.
