ABSTRACT:
The present inventive apparatus measures the output of urine optically, totalizes it and prints it on a self-adherent paper which can easily be afixed to the hospital chart. The apparatus includes a measurement column, an optical sensor to determine when the measurement column is empty, a peristaltic pump to empty the measurement column at a known rate, into a collection bag or specimen bottle and control logic to determine the volume removed from the column based on the pump rate. A display is also provided for easy observation of current output statistics. Specimens can be collected under automatic or manual control for biochemical analysis without contamination by contact or alteration by electrical current. An alarm may be sounded when the collection bag is in need of replacement, or when the urine output falls or rises to predetermined rates.
