The Uro Checker uses a mass sensor to measure the urine collected in the Uro Bag in real time, and displays the amount of urine over the specified time period. This product automates the nurse’s task of measuring and recording urine output, thereby reducing nursing workload. It also measures urine output in real time, allowing early detection of changes in the patient’s condition. In addition, it reduces the number of Uro Bag discharges and helps reduce the risk of staff exposure and the risk of urinary tract infections in patients. The Hemato Check Module uses an optical sensor to measure the hemoglobin concentration in the urine from outside the tube. The Uro Logger aggregates the urine output measurement from the Uro Checker via WiFi or other means, checks the graphs, and notifies the staff remotely.
