FIELD: medicine.
SUBSTANCE: group of inventions refers to medical equipment. An uropoiesis measurement apparatus for a patient using a catheter comprises an independently emptying siphon chamber which contains an inlet hole for connection to the catheter and an outlet hole for urine an amount of which is to be measured. A base unit of the apparatus has an attachment organ for detachable connection of the siphon chamber thereto, and an element measuring the urine level in the siphon chamber. Two capacitor electrodes of the measuring element are spaced from each other. A capacitor electrode signal between the two electrodes varies with the varying urine level in the siphon chamber and represents a urine measure. Urine is passed into the siphon chamber. The urine level is continuously measured in the siphon chamber with using two capacitor electrodes provided in the base unit. The events of independent emptying of the siphon chamber are detected. The uropoiesis is followed as time functions by measuring the urine level and detecting the events of independent emptying.
EFFECT: using the group of inventions enables providing more accurate real-time measurements.
