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.
Claims26
An arrangement adapted for enhanced continuous flow of urine in a catheterized patient, the arrangement comprising a catheter for insertion to the patient, a urine collection bag and a tube having an inner diameter of from four millimeters to six millimeters, said tube having an inner surface which is hydrophobic and polished at least along a first segment thereof and being adapted to provide a continuously negative fluid pressure therein, said tube being connected to said catheter at one end of said tube, and said tube being connected to said collection bag at an opposite end 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.
A method of collecting urine from a patient having a catheter inserted into a urinary bladder, the method comprising providing a hydrophobic tube with a polished inner surface having an inner diameter of from four millimeters to six millimeters, wherein said tube comprises an ascending portion having a vertical height hr and a descending portion having a vertical height hd, wherein a difference between hr and hd is less than 60 mm, wherein said tube has an inner surface which is hydrophobic at least along a first segment thereof and is adapted to provide a continuously negative fluid pressure therein;
- connecting said tube to said catheter at one end and connecting said tube to a urine collection bag at an opposite end.
A method for enhanced continuous flow of urine in a catheterized patient comprising:
- a. providing an arrangement comprising a hydrophobic tube with a polished inner surface having an inner diameter of from four to six millimeters, said tube having an inner surface which is hydrophobic at least along a first segment thereof and being arranged to provide a continuously negative fluid pressure therein;
- b. non-releasably attaching said hydrophobic tube to said urinary catheter unit, and releasably attaching said tube to a urine collection bag, said catheter unit being adapted to continuously remove fluid from a bladder of the patient and to convey said fluid into said tube under a continuously negative fluid pressure;
- and conveying a column of fluid held by a meniscus of said column of fluid from said catheter to said collection bag without interruption, without manual manipulation of said tube or said collection bag.
An arrangement adapted for enhanced continuous flow of urine in a catheterized patient having a bladder, the arrangement comprising a catheter for insertion to the patient, a urine collection bag and a catheter tube having an inner diameter of from four millimeters to six millimeters, wherein said tube comprises an ascending portion having a vertical height hr and a descending portion having a vertical height hd, wherein a difference between hr and hd is less than 60 mm, said tube having an inner surface which is hydrophobic and polished at least along a first segment thereof and being adapted to provide a continuously negative fluid pressure for draining the bladder;
- wherein said catheter tube is connected to said catheter at one end of said catheter tube, and said catheter tube is connected to said collection bag at an opposite end of said catheter tube, such that said catheter tube is adapted for conveying a column of fluid held by a meniscus of said column of fluid from said catheter to said collection bag without interruption.
