Abstract
Liquid-measuring apparatus for measuring the drainage of urine from a patient comprises a measuring cylinder and a bag which is of substantially larger capacity than the cylinder and is situated beneath the cylinder. Tubing extends downwardly to the bag from within a compartment of the cylinder, the compartment being formed by an additional tube which is closed at its upper end and perforated near its lower end. The cylinder is vented to ambient atmospheric pressure above the level of the upper end of the tubing connected to the bag. Every time urine collected in the cylinder reaches this level, an automatic siphon action drains a predetermined quantity of the urine from the cylinder, through the compartment and the tubing, into the bag. The total quantity of urine drained from the patient can be measured at any time by means of a coarse reading taken from the bag and a fine reading taken from the cylinder.
