Abstract
The present invention provides an arrangement (200) adapted for enhanced continuous flow of urine in a catheterized patient, the arrangement comprising a catheter tube (204) 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.
Claims21
A catheter tube with two ends, adapted for connecting to a catheter at a first end and to a urine collection bag at a second end, wherein said catheter tube comprises a tube having an inner diameter of less than six millimeters, said tube having an inner surface which is hydrophobic and polished along at least a first segment of said tube, such that said tube conveys a column of fluid held by a meniscus of said column of fluid from said catheter to said collection bag without interruption by eliminating substantially all air traps in said tube during operation, wherein said tube comprises an ascending portion having a first vertical height and a descending portion having a second vertical height, and a difference between said first vertical height and said second vertical height is less than 60 millimeters.
A method of collecting urine from a patient having a catheter inserted into a urinary bladder, the method comprising providing a tube with two ends, adapted for connecting to a catheter at a first end and to a urine collection bag at a second end, an inner diameter of said tube being less than six millimeters, an inner surface of said tube being hydrophobic and polished along at least a first segment thereof, such that said tube conveys a column of fluid held by a meniscus of said column of fluid from said catheter to said collection bag without generating an air trap in said tube during operation;
- wherein said tube comprises an ascending portion having a first vertical height and a descending portion having a second vertical height, wherein a difference between said first vertical height and said second vertical height is less than 60 millimeter;
- connecting said tube to said catheter at one end and connecting said tube to said urine collection bag at an opposite end;
- and continuously draining said bladder.
