Apparatus to secure and adjust flexible conduit
The invention provides an apparatus and method of securing a length of flexible conduit to a subject, and adjusting the flexible conduit to a length tailored to the subject, in order to reduce or eliminate excess conduit traversing the subject's body. The apparatus comprises a base with elongate channels for accepting flexible conduit, a lid which mates with the base, and a securing member for attaching the mated base and lid to the body of the subject.
1. An apparatus adapted to secure a flexible conduit to a subject's body and to adjust the length of the flexible conduit to conform to the portion of the subject's body being traversed by the flexible conduit, comprising:
a rigid base comprising three approximately parallel elongate channels, each channel having a proximal opening at a first end of the base and a distal opening at a second end of the base, and each channel having an open upper surface into which the flexible conduit is inserted to traverse the length of the channel;
a rigid lid which releasably mates to said base to enclose the open upper surface of each elongate channel such that a segment of the flexible conduit is retained within each channel and exits each channel at the proximal and distal opening thereof, the flexible conduit describing an “S” configuration by traversing a first of said three channels in a proximal-to-distal orientation, traversing a second of said three channels in a distal-to-proximal orientation, and traversing a third of said three channels in a proximal-to-distal orientation,
wherein adjusting the length of each loop of the “S” configuration adjusts the length of the flexible conduit to conform to the portion of the subject's body being traversed by the flexible conduit, and
wherein portions of the lid which contact the segment of the flexible conduit retained within each channel comprise one or more raised structures which, upon mating of the base and lid, engage without encircling the segment of the flexible conduit to reduce slippage of the flexible conduit through the channel by increasing frictional force applied to the flexible conduit; and
a securing member configured to releasably secure the mated base and lid on the body of the subject.
2. The apparatus of claim 1 , wherein the base and lid are secured to one another by a hinge region.
3. The apparatus of claim 2 , wherein the base and lid are mated to one another by an adhesive tape closure.
4. The apparatus of claim 2 , wherein the base and lid are mated to one another by a friction fit closure.
5. The apparatus of claim 2 , wherein the base and lid are mated to one another by a releasable clip closure.
6. The apparatus of claim 1 , wherein the flexible conduit comprises a catheter.
7. The apparatus of claim 1 , wherein the flexible conduit comprises an intravenous tube.
8. The apparatus of claim 1 , wherein the flexible conduit comprises an insulated cable carrying one or more conductors.
9. The apparatus of claim 1 , wherein the securing member comprises an adhesive pad, an adhesive strap, a hook and loop strap, a strap with snap closures, or a strap with a buckle.
10. A method of securing a flexible conduit to a subject's body and adjusting the length of said flexible conduit to conform to the portion of the subject's body being traversed by the flexible conduit, comprising:
affixing the apparatus of claim 1 to the body of the subject using a securing member configured to releasably secure the base and lid on the body of the subject;
inserting the flexible conduit into each of the three approximately parallel elongate channels of the apparatus, such that a segment of the flexible conduit is retained within each channel and exits each channel at the proximal and distal opening thereof, the flexible conduit describing an “S” configuration by traversing the first of said three channels in a proximal-to-distal orientation, traversing the second of said three channels in a distal-to-proximal orientation, and traversing the third of said three channels in a proximal-to-distal orientation;
adjusting the length of each loop of the “S” configuration to adjust the length of the flexible conduit to conform to the portion of the subject's body being traversed by the flexible conduit; and
releasably mating the lid and base of the apparatus.
11. The method of claim 10 , wherein the base and lid are secured to one another by a hinge region.
12. The method of claim 11 , wherein the base and lid are mated to one another by an adhesive tape closure.
13. The method of claim 11 , wherein the base and lid are mated to one another by a friction fit closure.
14. The method of claim 11 , wherein the base and lid are mated to one another by a releasable clip closure.
15. The method of claim 10 , wherein the flexible conduit comprises a catheter.
16. The method of claim 10 , wherein the flexible conduit comprises an intravenous tube.
17. The method of claim 10 , wherein the flexible conduit comprises an insulated cable carrying one or more conductors.
18. The method of claim 10 , wherein the securing member comprises an adhesive pad, an adhesive strap, a hook and loop strap, a strap with snap closures, or a strap with a buckle.
19. The method of claim 10 , wherein the attachment point on a subject's body comprises a limb, and wherein the flexible conduit is longer than the subject's limb and is adjusted such that the length traversed by the flexible conduit is less than the length of the subject's limb.
20. The method of claim 19 , wherein the limb is an arm.
