Benefits of technology

The invention is a method for automatically removing urine from a patient using a suction device. The method involves using a catheter to collect the urine, which is then transported to a receptacle or canister through a suction regulator that controls the amount of suction. The suction can be adjusted from a maximum value to a minimum value to regulate the flow of urine. The method can be used at different elevations and can provide a flow rate of up to 100 liters per minute. The urine is transported through the suction regulator using air flow, and the flow rate is determined by the difference in pressure between the external catheter and the suction regulator. The method can be used with a differential pressure of no more than 55 mmHg or 100 mmHg to achieve an air flow rate of greater than 25 or 35 liters per minute, respectively. The ratio of air flow rate in liters per minute squared to the regulated value should be at least 13 for optimal drainage of urine.

Problems solved by technology

However, the use of higher vacuum pressure poses an increased risk to the patient, as the only opening in the circuit for air to relieve the pressure is adjacent the patient's genitalia.
Accordingly, use of increased vacuum pressure to increase the flow rate of urine being withdrawn into the canister runs the risk of injury to the delicate issue adjacent the urethral opening.

Abstract

A method for automatically removing by suction urine voided by a female by use of a system that includes an external catheter, a suction canister and a suction regulator. The external catheter is applied at the urethra opening to receive urine voided by the female. The suction canister collects the urine and is coupled to a source of suction providing suction having a first value. The suction regulator is interposed between the external catheter and the canister to regulate the amount of suction to a regulated value which is applied the external catheter, whereupon urine from the external catheter is carried through the suction regulator and into the canister.
