BRIEF DESCRIPTION OF THE DRAWINGS

FIGS. 1A and 1B are top views of an exemplary embodiment of a transporter and an absorbent pad, respectively, of the present disclosure.

FIG. 2 is a perspective view illustrating an example of how an absorbent pad shown in FIG. 1B can be connected with a transporter shown in FIG. 1A.

DETAILED DESCRIPTION OF THE DISCLOSURE

Referring to the Figures, and in particular, to FIG. 1A and FIG. 1B, there is provided an absorbent pad 20 that can be removably connected to transporter 10.

Absorbent pad 20 shown in FIG. 1B is positioned on a top surface of transporter 10 shown in FIG. 1A, to absorb blood and/or other body fluids from the person being transported.

Absorbent pad 20 can be any size and shape that permits it to be positioned, preferably removably, on transporter 10. As shown in the exemplary embodiment provided in FIG. 1A, transporter 10 has a top portion 12 and a bottom portion 14 that are delineated from main body 16 by stitch lines 13, 15, respectively. In a normal transporter 10, top portion 12 and bottom portion 14 are made by two or more layers and sewn or connected together along stitch lines 13, 15, respectively. In the present disclosure, one exemplary embodiment provides for the formation of a pocket 32 in top portion 12 and a pocket 34 in bottom portion 14. The pocket is formed by the materials of the transporter 10 but without stitch lines, so that the pocket is enclosed along horizontal edge 44 and the two vertical edges 46, 48.

Transporter 10 has hand-holds 11 along the sides thereof. Referring to FIG. 1B, absorbent pad 20 has a shape that covers a large portion of the top surface of transporter 10. Absorbent pad 20 can have one or more cut-outs 21, 26 that are preferably die-cut, to provide better access to the hand-holds by those persons carrying the transporter, and do not compromise the strength and integrity of the transporter 10. However, absorbent pad 20 can also be shaped without cut-outs 21, 26.

Absorbent pad 20 can be shaped to have a top segment 22 and/or a bottom segment 24. Top segment 22 extends from an upper edge 23 of absorbent pad 20 to anywhere to an uppermost edge 27 of a first cut-out 21. Likewise, bottom segment 24 extends from edge 25 of absorbent pad 20 to anywhere to a bottom-most edge 29 of cut-out 26. The area of absorbent pad 20 between top segment 20 and bottom segment 24 is body portion 40.

As illustrated in FIG. 2, top segment 22 of absorbent pad 20 can be inserted into top pocket 32. Likewise, although not illustrated in FIG. 2, bottom segment 24 can be inserted into bottom pocket 34. Insertion of segments 22, 24 of absorbent pad 20 into their respective pockets secures the position of absorbent pad 20 on transporter 10, without adhesive or fasteners. Accordingly, body portion 40 is of a sufficient axial or vertical extant that top segment 22 and bottom segment 24 can reach and be inserted into their respective pockets 32, 34. Significantly, absorbent pad 20 is thereby free to shift or be adjusted when positioned on transporter 10 in order to meet the needs of the injured person being transported. After use, absorbent body 20 can be easily removed from transporter 10 as a single, individual piece.

Absorbent pad 20 can have a top layer (or body contact surface) 50 that does not adhere to the person, and that permits blood and other body fluids to pass through to the absorbent or superabsorbent layers in the absorbent pad. In this way, absorbent pad 20 keeps the injured person dry and comfortable, and reduces the risk of contamination.

Top layer 50 can be made of a polymer film, such as polyethylene or polypropylene film. Another embodiment of absorbent pad 20 has top layer 50 that is made of non-woven material, such as airlaid formed on a non-woven. Top layer 50 of absorbent pad 20 can also be made of a non-slip material, or treated with a non-slip agent or coating, to reduce movement or slipping of a person being carried on transporter 10.

Absorbent pad 20 has an absorbent material or superabsorbent material that is able to absorb large amounts of fluids, such as water, blood and/or other body fluids. Examples of absorbent and superabsorbent materials that can be used for absorbent pad include, but are not limited to, an airlaid, an airlaid composite, fluff pulp, bonding fiber, superabsorbent polymer (SAP), compressed SAP composite of SAP polymer granules adhered with one or more binders and/or plasticizers, compressed composite containing a percentage of short or microfiber materials, thermoplastic polymer fibers, thermoplastic polymer granules, cellulose powders, cellulose gels, an airlaid with SAP, a fibrous or foam structure that has been coated or impregnated with a SAP, an absorbent structure having one or more starch or cellulose based absorbents or containing superabsorbent material formed and/or crosslinked, or any combinations thereof. Superabsorbent materials used in the present disclosure can be used in various forms that include, but are not limited to, granular, fiber, liquid, superabsorbent hot melts, or any combinations thereof.

Absorbent pad 20 may also contain, or be treated with, a surfactant. The surfactant enhances absorption of fluids by absorbent pad 20. The amounts of surfactant used can be controlled to regulate the rate of wicking or absorption of absorbent pad 20. Examples of surfactants that can be used in the present disclosure include anionic surfactant, cationic surfactant, zwitterionic surfactant, and non-ionic surfactant.

Absorbent body 20 may have one or more strengthening layers to improve the strength and/or resistance to tearing of absorbent body 20. The one or more strengthening layers can be located on top of, below, or in between any portion of absorbent body 20. A strengthening layer of absorbent body 20 may be made of standard non-woven material, or meltblown or spunlace composites. An exemplary embodiment is a strengthening layer made of polypropylene non-woven material or polypropylene/meltblown non-woven material.

Absorbent pad 20 and/or transporter 10 can also contain one or more active agent. The active agent can be positioned anywhere on and/or in absorbent pad 20 or transporter 10, to reduce infection and contamination of the transporter by microbial pathogens, and to reduce and/or eliminate odors. The active agent is preferably positioned in or on absorbent pad 20. The active agent includes, but is not limited to, a bactericide, fungicide, virucide, disinfectant, sanitizer, sterilizer, mildewstat, surfactant, deodorizer, and/or any combinations thereof. Active agents include, but are not limited to, a metal, metal compound, surface active agent, quaternary ammonium compound, organic acid, inorganic acid, salt, sulfite, biopolymer, synthetic polymer, chitin, chitosan, nisin, enzyme, arginate, diacetate, antioxidant, or any combinations thereof. An active agent may be present at absorbent pad 20 or transporter 10 in its active form, or present in an inactive form that becomes activated upon contact with fluids, such as body fluids from the person being carried, or water.

An adhesive material or one and/or more fasteners can be used to removably connect absorbent body 20 to transporter 10. Examples of adhesive materials or fasteners that can be used to connect absorbent pad 20 to transporter 10 include, but are not limited to, glue, two-sided tape, thread, button, snap, zipper, or a hook-and-loop interlocking device such as VELCRO® (Velcro Industries B.V. LLC Netherlands, Curacao, Netherlands Antilles). There may be one or more attachment points for the adhesive material or fastener. For example, if VELCRO® is used to removably connect absorbent pad 20 to a transporter, the male/female attachment points can be the underside of absorbent pad 20 and the top surface of transporter 10, respectively, or vice versa. After use, absorbent pad 20 can be completely detached from transporter 10 and disposed of, and a new absorbent pad positioned on the transporter in its place.

Transporter 10 can be any transporter suitable for carrying an injured person. Examples of transporters for which the removable absorbent pad 20 of the present disclosure can be used include: the disposable transporter disclosed in International Application No. PCT/US2008/0002907, and the lightweight transporter with anti-hypothermia structures disclosed in International Application No. PCT/US2008/076293, both of which are hereby incorporated by reference. The removable absorbent pad 20 of the present disclosure can also be of a size and shape to fit on attachments to a transporter, such as the absorbent head cover disclosed in International Application No. PCT/US2009/031007, which is hereby incorporated by reference. In addition, absorbent pad 20 can be used with transporters having structures that provide additional rigidity and support, including inflatable channels or chambers, and/or rigid bodies that are passed through holes or channels in the transporter, where such rigid bodies may be solid or hollow, and made of metal, polymer, and/or wood.

The disclosures herein are exemplary, and should not be construed as implying any particular limitation. It should be understood that various alternatives, combinations and modifications could be devised by those skilled in the art. The present disclosure is intended to embrace all such alternatives, modifications and variances that fall within the scope of the disclosure herein.
