Abstract
An arrangement adapted for enhanced continuous flow of urine in a catheterized patient, the arrangement comprising a catheter tube having an inner diameter of less than six millimeters, said tube having an inner surface which is hydrophobic at least along a first segment thereof and being adapted to provide a continuously negative fluid pressure therein.
Claims16
A catheter tube comprising:
- two ends, adapted for connecting to a catheter at a first end and to a urine collection bag at a second end, said catheter tube having an inner diameter of less than six millimeters and having an inner surface which is hydrophobic and polished, wherein said catheter tube is arranged and configured to continuously provide negative pressure in said tube in order to convey a column of fluid held by a meniscus of said column of fluid within said catheter to said collection bag and prevent the formation of an air trap within said catheter tube and prevent a formation of a bolus of urine within a bladder of a patient;
- and,
- a clamp disposed on the catheter tube between the first end and the second end and configured to maintain the negative pressure within said catheter tube when said catheter tube is disconnected from the urine collection bag.
A catheter tube comprising:
- two ends, adapted for connecting to a catheter at a first end and to a urine collection bag at a second end, said catheter tube having an inner diameter an inner diameter of from four millimeters to six millimeters and having an inner surface which is hydrophobic and polished, wherein said catheter tube is arranged and configured to continuously provide negative pressure in said tube in order to convey a column of fluid held by a meniscus of said column of fluid within said catheter to said collection bag and prevent the formation of an air trap within said catheter tube and prevent a formation of a bolus of urine within a bladder of a patient;
- and,
- a clamp disposed on the catheter tube between the first end and the second end and configured to maintain the negative pressure within said catheter tube when said catheter tube is disconnected from the urine collection bag.
