Assembly for urinary drainage
The present invention provides an assembly for urinary drainage. The assembly comprises a urinary drainage device for collecting urine from a body opening and a collecting bag for collecting the urine. The collecting bag comprises a compartment between sheets of a foil material and an inlet into the compartment, which inlet is connected to the device such that a urinary flow can be established in a flow path from the device through the inlet and into the compartment. The collecting bag further comprises a flow promoting element arranged between the sheets and having flow promoting properties. The collecting may also comprise suction means for providing suction through a flow path in the collecting bag.
1. An assembly for urinary drainage comprising:
a urinary drainage device for collecting urine from a body opening;
a urine collecting bag connected to the urinary drainage device;
an expansion element disposed inside of the urine collecting bag; and
a trigger operable to expand the expansion element;
wherein the expansion element is a slit-plate comprising a plate shaped element with at least two rows of slits, where slits of a first row of slits extend from a first edge of the plate shaped element to more than halfway towards an opposite, second, edge of the plate shaped element, where slits of a second row of slits extend from the second edge of the plate shaped element to more than halfway towards the first edge of the plate shaped element, and where the slits in the first row of slits are offset from the slits of the second row of slits.
2. An assembly according to claim 1 , wherein the urinary drainage device is a telescopic catheter.
3. An assembly according to claim 2 , wherein the trigger is coupled to a telescopic mechanism of the telescopic catheter.
4. An assembly according to claim 1 , wherein the trigger is operated manually.
5. An assembly according to claim 1 , wherein the urinary drainage device is connected to an inlet of the urine collecting bag by a slidable connecting element.
6. An assembly according to claim 1 , wherein the expansion element is a shape memory element.
7. An assembly according to claim 1 , wherein the slit-plate comprises a weakening line.
8. An assembly according to claim 1 , wherein the trigger is a string connected to the expansion element.
9. An assembly according to claim 1 , wherein the urine collecting bag is elastic.
10. An assembly according to claim 1 , wherein the urine collecting bag is a concertina folded urine collecting bag.
11. An assembly configured to collect urine, the assembly comprising:
a urinary catheter;
a urine collecting bag connected to the urinary catheter; and
an expansion plate disposed inside of the urine collecting bag, the expansion plate including a plurality of slit openings formed through a thickness of the plate,
wherein the plurality of slit openings includes a first row of openings, with each opening extending from a first edge of the expansion plate a distance of more than halfway towards an opposite, second edge of the expansion plate.
12. The assembly of claim 11 , wherein the plurality of slit openings includes the first row of slit openings spaced apart and offset from a second row of slit openings.
13. The assembly of claim 11 , wherein the expansion plate is configured to expand from a first thickness to a second expanded thickness that is larger than the first thickness.
14. The assembly of claim 11 , wherein the expansion plate is fabricated from one of paper, plastic, cardboard, and metalized foil.
15. The assembly of claim 11 , wherein the plurality of slit openings includes a second row of openings, with each opening extending from the second edge of the expansion plate a distance of more than halfway towards the first edge of the expansion plate.
