Female fluid removal device
A urine removal device includes a plurality of layers suitable to capture and transfer urine. A conduit system is disposed inside of the device and extends from the proximal portion of the device, where it interfaces via an outlet conduit member, to the distal end of the device where it draws in urine from the device. The device allows air flow through the device to support suction that is applied. The fluid layer system has at least one conduit configured to draw urine from the distal portion of the device up to the proximal end of the device, and into the outlet conduit where it exits the urine removal device.
1. A device for removing urine discharged from a body of a user, the device comprising:
a fluid collection region comprising:
an inner layer that is permeable to urine,
an outer layer that is substantially impermeable to urine,
a transfer layer disposed between the inner layer and the outer layer, and
an overhang layer that at least partially overlaps a periphery of the inner layer;
a first suction conduit extending from a proximal end region of the device and along a right side of the fluid collection region between the inner layer and the outer layer and ending in a first fluid inlet at a distal end region of the right side of the fluid collection region;
a second suction conduit extending from the proximal end region of the device and extending along a left side of the fluid collection region between the inner layer and the outer layer and ending in a second fluid inlet at a distal end region of the left side of the fluid collection region;
a first gravity activated valve in fluid communication with the first suction conduit and configured to close when the first fluid inlet is held laterally above the second fluid inlet; and
a second gravity activated valve in fluid communication with the second suction conduit and configured to close when the second fluid inlet is held laterally above the first fluid inlet.
2. The device of claim 1 , wherein one or both of the first and second gravity activated valves comprises a ball check valve.
3. The device of claim 1 , wherein one or both of the first and second gravity activated valves comprises a flap valve.
4. The device of claim 1 , wherein the overhang layer forms an annulus over the inner layer on an outside of the fluid collection region.
5. The device of claim 1 , wherein the overhang layer is at least partially unattached where it overlaps the inner layer.
6. The device of claim 1 , wherein the overhang layer does not absorb urine.
7. The device of claim 1 , further comprising a frame having a base region and at least one branch extending from the base region along a substantial length of the device wherein the at least one branch is curved to conform to the body of the user.
8. The device of claim 7 , further comprising an adhesive patch attached to the base region for attaching the device to a patient.
9. The device of claim 7 , wherein the at least one branch has a variable thickness along its length.
10. The device of claim 7 , wherein the at least one branch has a stepped thickness along its length.
11. The device of claim 7 , wherein each branch of the frame tapers laterally along its length.
12. The device of claim 1 , wherein the first and second suction conduits are curved to conform with a vaginal region.
13. The device of claim 1 , further comprising an adhesive patch attached to at least one layer of the fluid collection region.
14. The device of claim 1 , wherein each suction conduit forms a sidewall of the fluid collection region with an air gap between the first suction conduit and the second suction conduit.
15. The device of claim 1 , wherein the inner layer and the outer layer are joined together around a periphery of the fluid collection region so that the first suction conduit and the second suction conduit are inside of the fluid collection region.
16. A device for removing urine discharged from a body of a user, the device comprising:
a frame comprising a base region and at least one branch extending from the base region along a proximal to distal length of the device, wherein the at least one branch is curved to conform to the body of the user;
a fluid collection region extending distally from the base region and supported by the at least one branch, the fluid collection region comprising:
an inner layer that is permeable to urine,
an outer layer that is substantially impermeable to urine,
a transfer layer disposed between the inner layer and the outer layer, and
an overhang layer that is impermeable to urine, the overhang layer forming an annulus around a periphery of the inner layer, wherein the overhang layer is at least partially unattached where it overlaps the inner layer;
a first suction conduit extending from a proximal end region of the device and along a right side of the fluid collection region between the inner layer and the outer layer and ending in a first fluid inlet at a distal end region of the right side of the fluid collection region;
