Abstract
A bleach compatible mattress cover made of a non-woven polyolefin material and defining an interior cavity. The interior cavity configured to receive a mattress structure which may include a first and second support structure disposed in the interior cavity. In certain embodiments, the mattress cover has a Moisture Vapor Transfer Rate of greater than or equal 400 to less than 10,000, 7500 or more particularly less than 5000 grams per square meter per day and a hydrostatic head of 100 cm or greater and passes ASTM 1670 and ASTM 1671.
Claims23
A mattress cover comprising:
- a cover member defining a cavity configured to receive a support structure therein;
- top and bottom panels of said cover member, wherein said top panel is made of a non-woven bleach compatible polyolefin material having a moisture vapor transfer rate (MVTR) of at least 400 grams per square meter per day and a hydrostatic head which is greater than 100 cm such that the MVTR and hydrostatic head of the material creates a cover which is breathable but impervious enough to inhibit liquids, bacteria and viruses from passing through the top panel of the cover;
- said top and bottom panels sealed around at least 60% of a periphery thereof to create said cavity;
- wherein the non-woven bleach compatible polyolefin material is a laminate material;
- the laminate comprised of polyolefin filaments and maintains the hydrostatic head and MVTR properties after exposure to cleaning with bleach in conformance with hospital cleaning procedures for Class II medical devices.
A single patient use mattress cover comprising:
- a bleach compatible cover comprising a non-woven polyolefin material which is configured to secure around a mattress;
- the bleach compatible cover passes ASTM 1670 and 1671 tests and has a moisture vapor transfer rate (MVTR) of at least 400 but less than 7500 grams per square meter per day and a hydrostatic head which is greater than 100 cm;
- wherein the non-woven polyolefin material is a laminate material;
- the laminate comprised of polyolefin filaments and maintains the hydrostatic head and MVTR properties after cleaning with bleach at a level adequate to kill C.difficile.
A mattress cover comprising:
- a cover member defining a cavity configured to receive a support structure therein;
- top and bottom panels of said cover member, wherein said top panel is made of a non-woven bleach compatible polyolefin material having a moisture vapor transfer rate (MVTR) of at least 400 grams per square meter per day and a hydrostatic head which is greater than 100 cm such that the MVTR and hydrostatic head of the material creates a cover which is breathable but impervious enough to inhibit liquids, bacteria and viruses from passing through the top panel of the cover;
- said top and bottom panels sealed around at least 60% of a periphery thereof to create said cavity;
- wherein the non-woven bleach compatible polyolefin material is a laminate material;
- the laminate comprised of polyolefin filaments and maintains the hydrostatic head and MVTR properties after cleaning with bleach at a level adequate to kill C.difficile.
A single patient use mattress cover comprising:
