Abstract
The disclosed relates to a lateral transfer support surface and method of making. The flexible material sheets are sealed to one another to form at least one chamber, at least one of the flexible material sheets having air exit holes therein. The flexible material sheets is made of a polymer selected from a group consisting of polyamide, polyester, polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof; and an additive comprising a blend or copolymer of (1) a first polymer selected from a poly-lactic acid (PLA), a polyhydroxyalkanoates (PHA) or a combination thereof and (2) a second polymer which is a poly-terephthalate.
Claims17
A lateral transfer support surface, comprising:
- flexible material sheets sealed to one another to form at least one chamber, at least one of the flexible material sheets having air exit holes therein, said flexible material sheets comprised of:
- a polymer selected from a group consisting of polyamide, polyester, polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof;
- and
- an additive comprising a blend or copolymer of (1) a first polymer selected from a poly-lactic acid (PLA), a polyhydroxyalkanoates (PHA) or a combination thereof and (2) a second polymer which is a poly-terephthalate.
A lateral transfer support surface comprising:
- flexible material sheets sealed one another to form at least one chamber, at least one of the flexible material sheets having air exit holes therein, said flexible material sheets comprised of:
- a non-biodegradable polymer selected from a group consisting of polyamide, polyester, polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof;
- and
- an additive comprising a blend or copolymer of (1) a first polymer selected from a poly-lactic acid (PLA), a polyhydroxyalkanoates (PHA) or a combination thereof and (2) a second polymer which is a poly-terephthalate;
- a polyurethane coating on the flexible sheets, said polyurethane coating having an additive comprising a blend or copolymer of (1) a first polymer selected from a poly-lactic acid (PLA), a polyhydroxyalkanoates (PHA) or a combination thereof and (2) a second polymer which is a poly-terephthalate.
A biodegradable lateral transfer support surface comprising:
- a. fabric;
- and
- b. hardware, wherein the fabric and hardware are both made from a material comprised of:
- i. a non-biodegradable polymer selected from a group consisting of polyamide, polyester, polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof;
- and
- ii. a biodegradable additive,
- wherein the fabric has a first hardness on the durometer scale and the hardware has a second hardness on the durometer scale, different than the first hardness on the durometer scale.
A biodegradable lateral transfer support surface comprising:
- a. a main body selected from polyamide or polyester;
- b. inflatable chambers comprise a non-biodegradable polymer selected from a group consisting of polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof;
- c. straps and handles selected from a group consisting of nylon, polyester, polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof;
- d. fasteners selected from a group consisting of nylon, polyester, polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof;
- and
- e. an additive added to each of the materials in a-d comprising a blend or copolymer of (1) a first polymer selected from a poly-lactic acid (PLA), a polyhydroxyalkanoates (PHA) or a combination thereof and (2) a second polymer which is a poly-terephthalate.
A method comprising:
- providing a polymer selected from a group consisting of nylon, polyester, polyethylene (PE), polypropylene (PP), polyvinylchloride (PVC) and combinations thereof;
- providing an additive comprising a blend or copolymer of (1) a first polymer selected from a poly-lactic acid (PLA), a polyhydroxyalkanoates (PHA) or a combination thereof and (2) a second polymer which is a poly-terephthalate;
- and
- wherein the non-biodegradable polymer is present in a concentration from 90-99.9 wt. %, the additive is present in a concentration from 0.1-10 wt. % and the additive has 30-70 wt. % of the first polymer and 30-70% of the second polymer;
- blending the polymer and the additive and forming a fabric;
- cutting the fabric into material sheets;
- perforating at least one sheet of the sheets;
- sewing the sheets into a lateral support surface with chambers and an opening to provide constant air flow.
