IMPROVED URINE MEASUREMENT DEVICE AND METHOD Russian patent published in 2018 - IPC A61B5/20 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, particularly urology, laboratory diagnosis, and can be used when it is necessary to measure the amount of urine in patients with a urinary catheter. To this end, a measurement system is disclosed, comprising an electronic measurement system including electrodes disposed outside a measurement chamber for measuring capacitance values that vary as the level of urine within the chamber rises; and/or a measuring chamber for urine comprises a self-discharging siphon device that is self-draining by draining through a siphon. In the cavity space of the urine measurement system there is a capsule with walls made of water-soluble material for releasing an oil mixture containing 90–100 % oil. Disclosed is a method for preventing deterioration of functionality and measurement accuracy in the urine measurement system. Method comprises applying an oil mixture to the inner surfaces of the urine measurement system. Also disclosed is the use the capsule to release an oil mixture when treating the cavity surfaces of the urine collection system.

EFFECT: inventions provide longer operation of the urine measurement system by using a hydrophobic coating preventing degradation of the walls of the system.
