FIG. 1A is an illustration of a protective sheet 100 having one or more elements consistent with the current description. The protective sheet 100 can comprise a transparent region 102. FIG. 1B is an illustration of an example of a transparent region 102 of the protective sheet 100 having one or more elements consistent with the current description. The transparent region 102 can be formed of a first material. The first material can be transparent. The first material can extend from a first end 104 of the protective sheet. The first material can be a transparent polymer material, a transparent polyurethane material, a transparent polyethylene material, a transparent vinyl material, mylar, or the like.

The protective sheet 100 can include a protective region 106. The protective region ′06 can be formed of a second material. The second material can be different from the first material. The second material can extend from a second end 108 opposite the first end 104 of the protective sheet 100. The second material can extend to the transparent region 102 such that the first material contacts the second material.

The protective sheet 100 can include an elasticated perimeter 110. The elasticated perimeter 110 can be configured to secure the protective sheet 100 onto a support platform for a human body (as shown in FIG. 2). For example, the elasticated perimeter 110 can be configured to secure the protective sheet 100 to the frame of a gurney, mattress of a gurney, a spinal board, a stretcher, or the like.

The protective sheet 100 can be configured to be oriented on the support platform so that the transparent region 102 covers at least a head of the human body and the protective region 106 covers at least portion of the human body below the head.

In some variations, the protective region 106 of the protective sheet 100 can comprise an outer layer 112 and an inner layer 114. The outer layer 112, for example, can be formed of polyurethane laminate material. The polyurethane laminate material can have one or more protective properties, including wind resistance, water resistance, warming properties, cooling properties, and the like. In some variations, the outer layer 112 can be formed from a composite material, a vinyl material, a polymer material, mylar, or the like.

The inner layer 114 of the protective region 106 can be formed, for example, of a tissue material. The tissue material can have one or more properties, including insulation, absorbency, softness, or the like.

In some variations, a material can be provided between the first end 104 of the protective sheet 100 and the transparent region 102. The material provided between the first end 104 of the protective sheet 100 and the transparent region 102 can be the same material as forms the protective region 106 of the protective sheet 100. In some variations, the material between the first end 104 and the transparent region 102 can be the same material as forming the transparent region 102.

The transparent region 102 can comprise an elasticated strip 116. The elasticated strip 116 can be disposed adjacent the first end 104 of the protective sheet 100. The elasticated strip can be configured to be disposed substantially parallel to the first end 104 of the protective sheet 100. The elasticated strip 116 can be configured to exert a force 118 onto the sides 120 of the transparent region 102. The force 118 exerted onto the sides 120 of the transparent region can cause the protective sheet to hug the support platform (as shown in FIG. 2).

FIG. 2 is an illustration of a protective sheet 100 being utilized on a gurney 122, the protective sheet 100 having one or more elements consistent with the current description. While a gurney is illustrated in FIG. 2, the presently described subject matter can be used on any human body support platform. For example, a hospital bed, a spinal board, an operating table, or the like. The corners 124 of the protective sheet 100 can be rounded.

The one or more ribs 126 can be configured to raise the protective sheet 100 above the patient when the protective sheet 100 is secured to the support platform. The one or more ribs 126 can include strips, pipes, tubes, or the like. The one or more ribs 126 can be formed from plastic. The one or more ribs 126 can be formed from tubing, tabs, ties, strips, or the like. In some variations, the one or more ribs 126 can be formed contiguously with the protective sheet 100. For example, the outer layer 112 can be formed from a material capable of being formed with different thicknesses and/or densities in different regions of the material.

In some variations, the protective sheet 100 can comprise at least one channel 128 disposed transversely across the protective sheet 100. The at least one channel 128 can be configured to contain a rib 126. The at least one channel 128 can be configured to cause the rib 126 to be maintained within the channel 128. In some variations, the at least one channel 128 can have closed ends 130.

FIG. 3A is an illustration showing a portion of a protective sheet 100 having one or more features consistent with the current description.

In some variations, a portion 142 of the protective sheet can be folded upon itself such that it overlaps a different portion 144 of the protective sheet. A leading edge 146 of the folded portion 142 can be attached to a corresponding portion 148 of the protective sheet 100. The leading edge 146 can be attached by stitching, plastic welding, using an adhesive, or the like. Folding a portion of the protective sheet 100 upon itself can form a channel 128 for receiving a rib 126. In some variations, one or more ribs 126 can be provided and positioned laterally across the protective sheet 100 during the manufacturing process. The protective sheet 100 can then be folded around the one or more ribs 126. The protective sheet 100 can have as many folds as there are ribs 126. In some variations, the one or more ribs 126 may be introduced into the channel(s) 128 of the protective sheet 100 after the folds have been formed.

In some variations, the one or more ribs 126 may have an adhesive applied to at least a portion of the one or more ribs 126. When the rib(s) 126 are inserted into the channel(s) 128, the adhesive on the rib(s) can adhere to the inside of the channel(s) 128 causing the rib(s) 126 to be retained in-place in the channel(s) 126.

While FIG. 3D shows the rib being disposed in a fold of the outer layer 112 of the protective sheet 100, such that the rib would be disposed on the outside of the protective sheet 100, the rib can be disposed in a fold, such that the rib would be disposed on the inside of the protective sheet 100.

This allows the patient's head to be covered and protected from the elements while allowing the patient to see their surroundings. Being able to observe surroundings facilitates the patient in reducing their anxiety. The transparent region 102 can comprise one or more ventilation apertures 150. The one or more ventilation apertures 150 can comprise at least one hole configured to facilitate the ingress and egress of air and/or moisture. In some variations, the one or more ventilation apertures 150 can be a mesh, an aperture covered by a flap, and/or other apertures. The one or more ventilation apertures 150 can include two sets of ventilation apertures disposed on either side of the central axis of the transparent region 102.

The transparent region 102 of the protective sheet 100 can be configured to facilitate persons outside of the protective sheet 100 to visually monitor the patient. A patient's mental status, anxiety level, or general health status can change over time. For example, a patient may start to vomit, lose consciousness, or the like.
