Abstract
A stretcher for patient support which has a roll of disposable sheeting beneath an end portion of the stretcher. Individual sheets are manually separated from the roll at transverse weakened sections in the sheeting material that are longitudinally separated by a distance greater than the length of a mattress pad plus twice its thickness. In one embodiment, a roll of disposable sheeting is encased within a housing that has a pivotally mounted openable section.
Claims6
A patient supporting structure which has a mattress pad and an attached roll of disposable sheet material, wherein the improvement comprises:
- said roll being in a continuous form that is free of connecting seams between sheet sections, said continuous form roll having a series of transverse weakened manually frangible sections that are held together by the sheet material itself in an unseamed structure, and said frangible sections are longitudinally separated by a distance substantially greater than the longitudinal length of the mattress, and the material is substantially uniform and unweakened between the longitudinally spaced frangible sections;
- wherein said sheet material has an upper layer of absorbent nonwoven cellulosic material having a fiber orientation in the longitudinal direction of the sheet material whereby each transverse frangible section cuts laterally across the longitudinally oriented fibers;
- and a bottom layer of water impervious thermoplastic film laminated thereto.
A patient support structure having a mattress pad in a roll of disposable sheet material attached thereto, wherein the improvement comprises:
- said roll of disposable sheet material having a center portion and opposite side portions folded inwardly toward such center portion;
- and an unrolling system on the patient support structure that delivers the disposable sheet material to a top surface of a mattress with the folded side portions superimposed on top of the center longitudinal portion of the sheet material;
- and said roll of sheet material being in a continuous form that is free of connecting seams between sheet sections, said continuous form roll having a series of transverse weakened manually frangible sections that are held together by the sheet material itself in an unseamed structure, and said frangible sections are longitudinally separated by a distance substantially greater than the longitudinal length of the mattress, and the material is substantially uniform and unweakened between the longitudinally spaced frangible sections;
- wherein said sheet material has an upper layer of absorbent nonwoven cellulosic material having a fiber orientation in the longitudinal direction of the sheet material whereby each transverse frangible section cuts laterally across the longitudinally oriented fibers;
- and a bottom layer of water impervious thermoplastic film laminated thereto.
A roll of disposable sheeting material for attaching to a patient support structure having a mattress pad, wherein the improvement comprises:
- said roll of sheeting material being in a continuous form that is free of connecting seams between sheet sections, said continuous form roll having a series of transverse weakened manually frangible sections that are held together by the sheet material itself in an unseamed structure, and said frangible sections are longitudinally spaced apart by a distance substantially greater than the length of such mattress, and the material is substantially uniform and unweakened between the longitudinally spaced frangible sections;
- and said disposable sheet material has a center body portion and side portions folded inwardly upon the center portion so the transverse weakened manually frangible sections of the side portions and center portion are aligned, whereby the sheet material can be conveniently manually separated while in such folded condition;
- wherein said sheet material has an upper layer of absorbent nonwoven cellulosic material having a fiber orientation in the longitudinal direction of the sheet material whereby each transverse frangible section cuts laterally across the longitudinally oriented fibers;
- and a bottom layer of water impervious thermoplastic film laminated thereto.
