Abstract

Embodiments described herein are directed to an external, female, gravity-based drainage system. The system includes a body having a front side and a rear side and a drainage tube extending from a bottom side. The body can include a finger groove disposed on the front side and configured to allow a user to grasp the body from the front side alone without any opposing force applied to the rear side. The user can then position the funnel, disposed on the rear side of the body, over a labia region to capture any fluids voided therefrom. The fluids can be directed towards the lumen of the drainage tube and directed towards a suitable receptacle. Advantageously, the shape of the drainage system can be easily grasped and manipulated from a single side which can be important for patients with limited manual dexterity.

Claims (32)

1. A drainage system, comprising:

a gripping body, including:

at least three finger grooves including opposing wedge-shaped grooves configured to provide an interference fit engagement with a finger placed therein; and

a funnel configured for positioning over a labia region of a female patient, the funnel disposed on a rear side of the gripping body between the opposing wedge-shaped grooves; and

a drainage tube in fluid communication with the funnel.

2. The drainage system according to claim 1 , wherein the opposing wedge-shaped grooves have a triangular cross-sectional shape.

3. The drainage system according to claim 1 , wherein the at least three finger grooves includes side-by-side grooves on a front side of the gripping body.

4. The drainage system according to claim 1 , wherein the funnel defines a spherical sector shape.

5. The drainage system according to claim 1 , wherein the gripping body defines a spheroidal shape.

6. The drainage system according to claim 1 , wherein the drainage tube includes a pleated section configured to articulate an axis of the drainage tube.

7. The drainage system according to claim 1 , wherein the gripping body is formed of a compliant material including one of a plastic, a polymer, an elastomer, a rubber, or a silicone rubber.

8. The drainage system according to claim 1 , wherein the gripping body is formed of a rigid material and includes a compliant material disposed over a portion thereof, the compliant material including one of a plastic, a polymer, an elastomer, a rubber, or a silicone rubber.

9. The drainage system according to claim 1 , wherein an axis of the funnel extends at an angle relative to an axis of the drainage tube.

10. The drainage system according to claim 1 , wherein the funnel extends to a spout disposed proximate a center point of the gripping body.

11. The drainage system according to claim 1 , wherein the drainage tube is coupled to a collection bag.

12. A method of using a drainage system, comprising:

grasping a gripping body of the drainage system, the gripping body comprising at least three finger grooves including opposing wedge-shaped grooves, the grasping including inserting a finger into each of the opposing wedge-shaped grooves, each finger engages the respective opposing wedge-shaped groove in an interference-fit engagement;

placing a funnel of the gripping body positioned between the opposing wedge-shaped grooves over a labia region; and

urinating into the funnel.

13. The method according to claim 12 , wherein a drainage tube is coupled to the gripping body and to a collection bag.

14. The method according to claim 13 , wherein the drainage tube includes a pleated portion configured to articulate an axis of the drainage tube.

15. The method according to claim 12 , wherein grasping the gripping body further includes placing two fingers in side-by-side grooves of the at least three finger grooves.

16. The method according to claim 15 , wherein the opposing wedge-shaped grooves have a triangular cross-sectional shape.

17. The method according to claim 12 , wherein the funnel defines a spherical sector shape.

18. The method according to claim 12 , wherein the gripping body defines a spheroidal shape.

19. The method according to claim 12 , wherein the gripping body is formed of a compliant material including one of a plastic, a polymer, an elastomer, a rubber, or a silicone rubber.

20. The method according to claim 12 , wherein the gripping body is formed of a rigid material and includes a compliant material disposed over a portion thereof, the compliant material including one of a plastic, a polymer, an elastomer, a rubber, or a silicone rubber.

21. The method according to claim 12 , wherein an axis of the funnel extends at an angle relative to an axis of a drainage tube in fluid communication with the funnel.

22. The drainage system according to claim 1 , wherein a trough of a wedge-shaped groove of the opposing wedge-shaped grooves extends along a linear axis and wherein a first wall of the wedge-shaped groove extends from the trough at an angle of less than 45° relative to a second wall of the wedge-shaped groove extending from the trough.

23. The drainage system according to claim 1 , wherein a trough axis of each finger groove of the at least three finger grooves extends parallel to each other.

24. The method according to claim 12 , wherein a trough of a wedge-shaped groove of the opposing wedge-shaped grooves extends along a linear axis and wherein a first wall of the wedge-shaped groove extends from the trough at an angle of less than 45° relative to a second wall of the wedge-shaped groove extending from the trough.

25. The method according to claim 12 , wherein a trough axis of each finger groove of the at least three finger grooves extends parallel to each other.
