Molded or extruded fluid collection devices, and related systems and methods
Examples relate to fluid collection devices, and related systems and methods. In some embodiments, a fluid collection device includes a fluid impermeable barrier and an elongated body that is at least partially fluid permeable. The fluid impermeable barrier has a distal end region and a proximal end region defining an aperture sized and dimensioned to have urine drawn therethrough by a vacuum source. The elongated body has a portion of the body that is free from being covered by the fluid impermeable barrier between the distal end region and the proximal end region and positioned on the fluid collection device to receive urine discharged from a urethra at least proximate to the portion of the body. The fluid collection device includes at least one of the fluid impermeable barrier being an injection molded fluid impermeable barrier or the body includes at least an extruded support.
1 . A fluid collection device, comprising:
a fluid impermeable barrier having a distal end region including a distal end cap and a proximal end region including a proximal end cap defining an aperture sized and dimensioned to have urine drawn therethrough by a vacuum source, the proximal end cap being separate from the distal end cap; and
an elongated body having the distal end cap and the proximal end cap secured thereto such that the elongated body has a portion of the elongated body between the distal end region and the proximal end region that is free from being covered by the fluid impermeable barrier and positioned on the fluid collection device to receive urine discharged from a urethra at least proximate to the portion of the elongated body, the elongated body including at least an extruded support; and
a shape memory polymer or metal that is positioned within the extruded support of the elongated body.
2 . The fluid collection device of claim 1 , wherein the elongated body includes:
the extruded support having a distal end region having the distal end cap secured thereto, a proximal end region having the proximal end cap secured thereto, and at least one slot extending longitudinally on the extruded support; and
a fluid permeable membrane covering the at least one slot on the extruded support.
3 . The fluid collection device of claim 2 , wherein the extruded support includes a channel extending longitudinally therethrough and in fluid communication with the at least one slot and the aperture of the fluid impermeable barrier.
4 . The fluid collection device of claim 3 , wherein:
the distal end region of the fluid impermeable barrier includes a reservoir of void space being positioned between the distal end region of the extruded support and at least a portion of the distal end cap effective to provide fluid communication between the at least one slot and the channel.
5 . The fluid collection device of claim 4 , wherein the fluid impermeable barrier includes a substantially fluid impermeable sheet secured to a portion of the elongated body with an adhesive and extending between the proximal end cap and the distal end cap.
6 . The fluid collection device of claim 4 , wherein:
the extruded support includes a rear side and a front side including two side slots extending longitudinally on the front side of the extruded support, the at least one slot being positioned between the two side slots;
a portion of the fluid permeable membrane is positioned within the two side slots; and
a portion of the fluid permeable membrane extends at least partially across the at least one slot.
7 . The fluid collection device of claim 6 , wherein the shape memory polymer or metal is positioned within each of the two side slots and securing the portion of the fluid permeable membrane positioned within the two side slots.
8 . The fluid collection device of claim 7 , wherein the shape memory polymer or metal includes an elongated U-shaped shape memory polymer or metal extending through the distal end cap and into the two side slots.
9 . The fluid collection device of claim 4 , wherein the extruded support includes a rear side and a front side, the at least one slot including three slots on the front side each having a center angled relative to the center of other slots of the three slots.
10 . The fluid collection device of claim 9 , wherein the fluid permeable membrane is wrapped around the front side and the rear side of the extruded support such that a portion of the fluid permeable membrane covers the three slots and extends at least partially across the opening of the fluid impermeable barrier.
11 . The fluid collection device of claim 9 , further comprising the shape memory polymer or metal extending longitudinally through the distal end cap and at least a portion of the extruded support.
12 . The fluid collection device of claim 4 , wherein the distal end cap includes an alignment feature extending partially into the channel at the distal end region of extruded support and the proximal end cap includes an internal port extending partially into the channel, the alignment feature included one or more slits providing fluid communication between the reservoir and the channel.
13 . The fluid collection device of claim 12 , wherein the extruded support includes a closed cell foam extrusion.
14 . The fluid collection device of claim 1 , wherein at least a portion of the shape memory polymer or metal includes a strip of shape memory polymer or metal positioned within the extruded support of the elongated body.
15 . The fluid collection device of claim 1 , wherein at least a portion of the shape memory polymer or metal includes a wire of shape memory polymer or metal positioned within the extruded support of the elongated body.
