Effectiveness of Proactive CSIRT Services.

A urine flow monitor for displaying preferably in digital form total patient urine output and also urine flow rate. Urine from the patient passes through a catheter and into a calibrated volume chamber of special configuration which permits use even under conditions of vertical misalignment and wherein electronically controlled valve means are located both above and below the chamber and optical sensor means are provided above the chamber and below the top valve means. With the lower valve means closed, filling of the chamber takes place until the point where the urine level reaches the optical sensor at which time, by virtue of electronic control, the upper valve will close and the lower valve will open, allowing the urine to pass into a collection receptacle such as a urine drainage bag. Concurrently with the operation of the valve means, a signal is sent to a console monitor to record the volume dumped into the receptacle and also to commence operation of the flow rate recorder.
