PORTABLE MEDICAL DEVICE FOR MEASURING GLUCOSE LEVEL IN BLOOD (VERSIONS) Russian patent published in 2016 - IPC A61B5/151 A61B5/157 G01N33/50 G01N35/10 

FIELD: medicine.

SUBSTANCE: portable medical device for measurement of glucose level in blood contains case with cassette-receiver, replaceable cassette with test-tape, placed into cassette-receiver and drive, which includes electric engine and transmission mechanism, intended for turning cassette reel with test-tape in such a way that cassette test-tape winds on reel with possibility of successive application of test-elements, located on test-tape. Transmission mechanism includes worm gear and multistage down gear. Worm in worm gear is engaged with worm wheel. Cylindrical cogwheels of multistage down gear are located between worm wheel and output cogwheel, directly connected with reel. Each of cylindrical cogwheels has ten cogs. Worm is installed directly on electric engine shaft. Cylindrical cogwheels have different from linear mutual location, in which centres of cylindrical cogwheels are located in angles of triangle or quadrangle. Axis of electric engine shaft rotation is located in oblique or perpendicular way relative to axes of rotation of cylindrical cogwheels.

EFFECT: reduction of size of transmission mechanism and noise, produced by it during operation, with simultaneous provision of torque, sufficient for reel rotation.
