Limb support and limb support fastening arrangement
A limb support fastening arrangement for fastening a limb support to a limb of a wearer is disclosed. The arrangement comprises a first and second fastening portion, the first portion comprising an inflatable chamber comprising an upper and lower chamber wall and a first fastener disposed proximate the upper chamber wall, the lower chamber wall being arranged in use, to extend proximate the limb of the wearer. The second portion similarly comprises an inflatable chamber comprising an upper and lower chamber wall and a second fastener disposed proximate the upper chamber wall, the lower chamber wall being arranged in use, to extend proximate the limb of the wearer. The fastener associated with the first portion is arranged to detachably couple with the fastener associated with the second portion to detachably couple the first and second portions together, by positioning the lower chamber wall of one portion over the upper chamber wall of the other portion.
1. A limb support fastening arrangement for fastening a limb support to a limb of a wearer, the arrangement comprising: a first and second layer, the first layer being disposed upon the second layer, the layers being bonded togetherto define a first wing portion; a second wing portion; a first fastening portion extending outwardly away from the first wing portion; and a second fastening portion extending outwardly away from the second wing portion,
the first fastening portion comprising an inflatable chamber defined between the first and second layers, and a first fastener on the second layer, the first layer being arranged, in use, to form an inner layer of the first fastening portion, such that the first layer of the first fastening portion is proximal the limb of the wearer, the second layer being arranged, in use, to form an outer layer of the first fastening portion, such that the second layer of the first fastening portion is distal to the limb of the wearer,
the second fastening portion comprising an inflatable chamber defined between the first and second layers, and a second fastener on the second layer, the first layer being arranged, in use, to form an inner layer of the second fastening portion, such that the first layer of the second fastening portion is proximal to the limb of the wearer and the second layer being arranged, in use, to form an outer layer of the second fastening portion, such that the second layer of the second fastening portion is distal to the limb of the wearer,
wherein each of the first fastener and the second fastener is disposed in a corresponding pocket disposed on the second layer of the respective first and second fastening portions and the first fastener is arranged to detachably couple with the second fastener to detachably couple the first fastening portion and the second fastening portion together, by contacting the first layer of the first/second fastening portion on top of the second layer of the second/first fastening portion thus preventing the first fastener and the second fastener from coming into contact with skin of the wearer of the limb support by virtue of the inflatable chamber.
2. The limb support fastening arrangement according to claim 1 , wherein the first and second fasteners comprise a plurality of first and second fasteners disposed proximate the second layer of at least one of the first and second fastening portions, respectively.
3. The limb support fastening arrangement according to claim 2 , wherein the plurality of first fasteners associated with the first fastening portion are arranged in spaced relation along the first fastening portion and the plurality of second fasteners associated with the second fastening portion are arranged in spaced relation along the second fastening portion.
4. The limb support fastening arrangement according to claim 3 , wherein the plurality of first fasteners are arranged in spaced relation along a longitudinal axis of the first fastening portion and the plurality of second fasteners are arranged in spaced relation along a longitudinal axis of the second fastening portion.
5. A limb support for supporting the limb of a wearer, the limb support comprising a plurality of inflatable chambers arranged in fluid communication, and a limb support fastening arrangement according to claim 1 , wherein the inflatable chambers of the first and second fastening portions of the fastening arrangement are arranged in fluid communication with the plurality of inflatable chambers of the limb support.
6. The limb support according to claim 5 , wherein the limb support fastening arrangement is formed integrally with the limb support.
7. The limb support according to claim 5 , further comprising an adapter for coupling the limb support to a source of pressurised fluid, for inflating the limb support.
8. The limb support fastening arrangement according to claim 1 , wherein the chambers of the first and second fastening portions are arranged in fluid communication.
9. The limb support fastening arrangement according to claim 1 , wherein the first and second fasteners comprise a plurality of first and second fasteners disposed proximate the second layer of the first and second fastening portions, respectively.
10. The limb support fastening arrangement according to claim 1 , wherein the first and second fasteners comprise magnets.
11. The limb support fastening arrangement according to claim 1 , wherein the inflatable chamber of the first fastening portion or the second fastening portion which overlaps the second fastening portion or the first fastening portion, respectively, becomes compressed when the first and second fasteners are coupled together.
