DETAILED DESCRIPTION

(28) Surgical cushions, typically comprise materials that do not permit fluids (such as air) to flow in or out. This protects surgical cushions from contamination, such as the absorption of liquids. However, the cushion needs to be compressible, by having air flow in and out of the cushion. Having vents on the cushion sides allows compressibility, but exposes the cushion to liquid contamination. Vents on the bottom of the cushion do not allow sufficient air flow when the cushion is attached to a table by conventional means such as hook-and-loop. Yet hook-and-loop fasteners allow the ability to blind-attach a cushion to a surface with relative ease.

(29) The embodiments disclosed herein provide solutions that can be used to locate the vent on the underside of the cushion to reduce the risk of liquid contamination while allowing air flow in and out of the cushion. The embodiments described also allow for blind-attachment of cushions to surgical tables while being much easier to clean and decontaminate than hook-and-loop fasteners.

(30) FIG. 1 shows a perspective view of an embodiment of a female component 10 with a round outer edge 11. In other embodiments, the female component 10, having one or more outer edges 11, can take any shape. The female component 10 can comprise one or more materials, such as urethane, vinyl, polyvinyl chloride, one or more metals, carbon fiber, wood, plastic, phenolic, any other suitable material, or any combination thereof. Any female component 10 may or may not comprise the same material(s) as any other female components 10. The female component 10 in some embodiments may be radiolucent, stain resistant, heat resistant, fire resistant, impact resistant, rust resistant, antimicrobial, electrically conductive (such as <1 mega-Ohm of resistance), electrically resistant, or any combination thereof.

(31) The female opening 12 depicted is a circle in the center of the female component 10. A circular female opening 12 allows for simplified blind attachment as it allows for coupling alignment at any orientation. The female opening 12 need not be a circle, and can take any other shape in various embodiments. In other embodiments, the female opening 12 can be located anywhere else in the female component 10. In the embodiment shown, the female opening 12 is a hole through the entire female component 10. In some embodiments, such as depicted in FIG. 1, the width of the female opening 12 can vary along its depth within the female component 10. The female opening 12 as shown has at least a broadest width 14 and a narrowest width 16, with any number of widths being possible. In other embodiments, the female opening 12 (at its mouth or at any depth) can be any shape for describing the size of the opening 12. The female opening 12 in some embodiments need not maintain any consistent shape, dimensions, or symmetry.

(32) In this embodiment, the top of the female component 10 is an arched female attachment surface 18. The female attachment surface 18 as shown has an interior slope 20 and an exterior slope 22 that converge to form a ridge 24. In this embodiment, the interior slope 20 forms a concave shape around the female opening 12. The narrowest width 16 in the female opening 12 can take the form of a flange or lip on the female attachment surface 18 (or any other surface), as shown in FIG. 1. Other embodiments may lack a flange or lip on the female attachment surface 18. In some embodiments, there may be no exterior slope 22. Other embodiments may converge an interior slope 20 and an exterior slope 22 to form a plateau. Different embodiments may lack an exterior slope 22. The female attachment surface 18 can have any shape (flat, curved, angled, plateaued, inclining, declining, any other shape, or any combination thereof) and/or any property (corrugated, etched, any other texture, adhesive, or any combination thereof).

(33) As depicted, the side 26 of the female component 10 can be smooth. Other embodiments can have a surface, as with any surface of the female component 10, which is uneven, corrugated, jagged, irregular, adhesive, non-symmetrical, etc. Some embodiments of the female component 10 may lack a side, such as having other surfaces meet at the side to form an arch.

(34) FIG. 1A is a perspective view of the other side of the female component 10, depicting a flat female mounting surface 28 opposite the female attachment surface 18. In this embodiment, the female opening 12 passes through the female mounting surface 18 to create a single female mounting surface hole 30 that, in this embodiment is the same width as the broadest width 14. The female mounting hole 30 allows fluid passage through the female component 10. In other embodiments, the female mounting surface 28 can be any shape (flat, curved, angled, plateaued, inclining, declining, any other shape, or any combination thereof) and/or have any property (corrugated, etched, any other texture, adhesive, or any combination thereof). Here, the female opening 12 has a wider width 14 along with a narrowest width 16. In some embodiments, the narrowest width 16 can take the form of a flange or lip on the female mounting surface 28, the female attachment surface 18, or both. Other embodiments may have no flange or lip.

(35) In some embodiments, the female mounting surface 28 is attached to an object such as a surgical cushion. In other embodiments, the female mounting surface 28 can be attached to surgical tables, walls, floors, vehicles, non-surgical cushions or pillows, any other type of object or surface, or nothing at all. The female mounting surface 28 can be attached in any manner, including (but not limited to) glue or other adhesive, welding, stitching, stapling, nailing, screwing, hook and loop, snaps, melting, riveting, any other suitable manner of attachment, or any combination thereof. In some embodiments, the female attachment surface 18 can be mounted in any manner described above with respect to the female mounting surface 28. In various embodiments, the female component 10 can be mounted or attached to any number of surfaces or objects, such as airline seats, train seats, boat seats, outdoor furniture, walls, ceilings, floors, pictures, curtains, automobiles, etc.

(36) FIG. 2 depicts another embodiment of female component 10a which is square in shape. In this embodiment, the female mounting surface 28a extends out into the female opening 12a. Here, there are four female mounting surface holes 30a within female mounting surface 28a which can each allow fluid passage through the female component 10a. Other embodiments can have any number of female mounting surface holes 30a within the female mounting surface 28a. Each female mounting surface hole 30a is smaller than the female opening 12a. Although each female mounting surface hole 30a is depicted as square in this embodiment, each female mounting surface hole 30a be any shape in other embodiments, where some or all of the female mounting surface holes 30a can have different shapes. In different embodiments, each female mounting surface hole 30a can have a different size and need not be symmetrically positioned with respect to each other and/or any axis. In various embodiments, one or more portions of the female mounting surface 28a can be detachable, comprise any combination of any of the materials recited for any other component discussed elsewhere, and/or have any properties discussed with respect to the female attachment surface 18a and/or the female mounting surface 28a. FIGS. 3 through 7 show various other embodiments of the female component (10b through 10f) of varying configurations, with differently shaped outer edges (11b through 11f), differently shaped female openings (12b through 12f), differently shaped female mounting holes (30b through 30f)

(37) FIG. 8 depicts another embodiment having a single female mounting surface hole 30g in the female mounting surface 28g to allow fluid passage through the female component 10g. The female mounting surface hole 30g is smaller than the female opening 12g. Although depicted as circular, the female mounting surface hole 30g can take any shape and size, and need not be centered.

(38) FIG. 9 depicts yet another embodiment. Although there is a female opening 12h in the female attachment surface 18h leading into the female component 10h, there is no hole in the female mounting surface 28h. This prevents the female opening 12h from extending all the way through the female component 10h. Here, the female mounting surface 28h comprises the same material as the rest of the female component 10h, and can be created as one solid piece. Various embodiments can also utilize a female mounting surface 28h that is a different solid material, a mesh, a semipermeable membrane, a vent, or any other type of configuration where the female opening 12h does not pass entirely through the female component 10h.

(39) FIG. 10 depicts an embodiment of a male component 100 shown in perspective view. The male component 100 can comprise one or more materials, such as urethane, vinyl, polyvinyl chloride, one or more metals, carbon fiber, wood, plastic, phenolic, any other suitable material, or any combination thereof. The male component 100 in some embodiments may be radiolucent, stain resistant, heat resistant, fire resistant, impact resistant, rust resistant, antimicrobial, electrically conductive (such as <1 mega-Ohm of resistance), electrically resistant, or any combination thereof. Any male component 100 may or may not comprise the same material(s) as any female component 10 or as any other male component 100.

(40) The top of the male component 100 comprises a male attachment member 102. In this embodiment, the male attachment member 102 has a cross shape formed out of a cylinder, with male attachment sides 104 forming the sides of the cylinder. Described differently, the male attachment member 102 is in the shape of a circle having male attachment member indentations 106 that extend through the male component 100 and project inward towards its center. The male attachment member 102 in other embodiments can take any other shape, and may lack male attachment member indentations 106. The top surface 108 of the male attachment member 102 can take any shape (flat, curved, angled, plateaued, inclining, declining, any other shape, or any combination thereof) and/or any properties (corrugated, etched, any other texture, adhesive, or any combination thereof).

(41) In some embodiments, there may be only one continuous male attachment side 104, which may be (for example) round, oval, or any other shape. In various embodiments, each male attachment side 104 can be straight or take any other type of shape, independent of any other male attachment side 104. In the embodiment depicted, each male attachment side 104 has a male attachment protrusion 110. In other embodiments, each male attachment side 104 can have any number of protrusions and/or indentations, or none at all.

(42) FIG. 10 further depicts a male mounting member 112 extending outwardly from the center of the male component 100 beneath the male attachment member 102 with a width that is greater than the male attachment sides 104 or male attachment protrusions 110. In other embodiments, the male mounting member 112 may simply be part of the male attachment member 102. In various embodiments, the male mounting member 112 can have any shape or configuration, which can include holes (not shown) or indentations 106 that need not match each other or be placed symmetrically.

(43) FIG. 10A depicts a flat male mounting surface 114 by which the male component 100 can be attached to a surface. In embodiments, the male mounting surface 114 can be any shape (flat, curved, angled, plateaued, inclining, declining, any other shape, or any combination thereof) and/or any property (corrugated, etched, any other texture, adhesive, or any combination thereof). In some embodiments, the male mounting surface 114 is attached to an object such as a surgical table. In other embodiments, the male mounting surface 114 can be attached to walls, floors, vehicles, surgical or regular cushions or pillows, any other type of object or surface, or nothing at all. The male mounting surface 114 can be attached in any manner, including (but not limited to) glue or other adhesive, welding, stitching, stapling, nailing, screwing, hook and loop, snaps, melting, riveting, any other suitable manner of attachment, or any combination thereof. In some embodiments, either or both the male mounting surface 114 or the male attachment member 102 can be mounted in any manner described above. In various embodiments, the male component 100 can be mounted or attached to any number of surfaces or objects, such as airline seats, train seats, boat seats, outdoor furniture, etc. FIGS. 10B and 10C show top and side views of the male attachment member 100.

(44) FIGS. 11 through 11C depict an alternate embodiment of a male component 100i. The male mounting member 112i has an outer ring 116i that forms four male mounting member holes 118i.

(45) FIG. 12 depicts an exploded view of the coupling 120 of a male component 100 into a female component 10, specifically the insertion of the male attachment member 102 into the female opening 12. In this embodiment, most widths of the interior slope 20 of the female attachment surface 18 exceed the width the male attachment member 102. The concave shape of the interior slope 20 of the female attachment surface 18 can therefore guide the male attachment sides 104. For example, a user holding the female component 10 affixed to an object (thus obstructing the view of the user), can guide the female opening 12 onto the male attachment member 102 based on the concave shape of the interior slope 20 of the female attachment surface 18. The same user could also perform the same guidance by handling a surgical cushion to guide the female opening 12 as it conforms to the male attachment member sides 104. Similarly, a user holding the male component 10 (or an object to which it is affixed), could guide (by tactile feedback alone) the male attachment member 102 into the female opening 12 by the conformance of the male attachment sides 104 to concave shape of the interior slope 20.

(46) FIG. 13 depicts an exploded view of the coupling 120i of a male component 100i into a female component 10i, in which the male component 100i is similar to that shown in FIG. 11.

(47) In some embodiments, the width of the male attachment protrusion 110 slightly exceeds that of the narrowest width 16 in the female opening 12. A user, object, or machine using sufficient force can push the male attachment protrusion 110 to a depth that is deeper inside the female opening 12 than the narrowest width 16. As shown in FIGS. 14 and 14A, this can result in a coupling (such as a snap-fit) of the male attachment member 102 into the female opening 12. In some embodiments, a snap-fit can be accompanied by the sound of a snap and/or a sudden penetration which quickly halts. Other embodiments can use any other type of sound and/or tactile feedback may be utilized to indicate coupling. In some embodiments, the snap-fit requires at least some force to remove (or unsnap) the male attachment member 102 from the female opening 12. In the embodiment depicted in FIGS. 14 and 14A, once coupled together, the male attachment member 102 and the female opening 12 are rotatable with respect to each other about the same central axis. The male attachment protrusion 110 can rotate at a depth within the female opening 12 that is deeper inside than the depth of the narrowest width 16. In some embodiments, there could be obstructions (not shown) within the female opening to restrict rotation to less than a full revolution. Some embodiments have a substantial correspondence in the shape of the female opening 12 and the male attachment member 102, although they need not be exactly the same. In such embodiments, the complimentary shape of one female opening 12 and a corresponding male attachment member 102 can be completely different from the shape that corresponds between another female opening 12 and its corresponding male attachment member 102. This could apply even if the female components 10 (or male components 100) are affixed to the same surface and/or object.

(48) FIG. 14 depicts an overhead view embodiment where a fluid (liquid or gas, for example) passageway 122 can form once a male component 100 is coupled to a female component 10. In other embodiments, a fluid passageway can be formed a male component 100 having sufficient proximity to a female component 10, even without coupling. In this embodiment, a surgical cushion has a female component 10 affixed, with the female opening 12 being a hole through the entire female component 10. A male component 100 is affixed to a surface. Fluid (such as gas or liquid) from the surgical cushion can exit through the female opening 12 and into the fluid passageway 122. Once in the fluid passageway 122, the fluid can then exit through the male attachment member indentations 106. In other embodiments, the fluid can instead exit through male mounting member holes 118.

(49) FIG. 14A depicts a side cross-sectional view of the same embodiment, where fluid can flow bi-directionally through the fluid passageways 122. This means that fluid can also enter through the male attachment member 102 through the male attachment member indentations 106, through the female opening 12, and into an affixed surgical cushion (not shown). In other embodiments, the male component 100 and/or the female component 10 may have a 1-way restriction to prevent or at least partially restrict the flow of fluid into either the male component 100 or the female component 10.

(50) FIG. 15 depicts an embodiment with a fluid-proof surgical cushion 124 having four affixed female components 10 which have been coupled to four corresponding male components 100 on a flat portion of a surgical table 126. In some embodiments, the male component 100 is affixed to an object (or surface) such as a surgical cushion 124 and the female component 10 is affixed to a surface (or object) such as a surgical table 126. Here, there are two couplings 120 between two female components 10 and two male components 100. There are also two sets of uncoupled male components 100 and female components 10, where the coupling can be done (for example) by force applied to the top side of the surgical cushion 124 once there has been blind alignment, which can (but need not) further include the sound and feel of a snap-fit.

(51) In some embodiments (not shown), each female component on a surgical cushion remains coupled to its corresponding male component on the surgical table, even as the surgical table bends. Due to the coupling, the surgical cushion compresses as it bends to conform with the bending surgical table. Air exits the surgical cushion due to the compression. Similarly, the surgical cushion may compress when weight (such as from a patient) is placed upon it. Conversely, air can enter the cushion (for example) when the surgical table where the bending angle of the surgical table is reduced or when weight previously placed upon the surgical cushion is reduced or eliminated. This could occur, for example, when a patient gets off of (or is removed from) a surgical cushion. In this embodiment, the female components provide the only way for fluid to leave or enter the surgical cushion. In various embodiments, some of the female components (or male components 100) that are affixed to the same object or surface may have features that are not present in other female components (or male components) in the group, respectively. For example, one female components affixed to a surgical cushion may have a semi-permeable membrane (not shown) on its backing surface. Another female component affixed to the same surgical cushion may lack such a semi-permeable membrane. In other embodiments, a female component 10 can be affixed to a table and a male component 100 can be affixed to a cushion.

(52) FIG. 16 depicts an embodiment with depicting a coupling 120 in a standard view affixed to a surgical table pad 124 as well as an exploded view of a coupling 120. The components in the exploded view include a male component 100 on top of a female component 10 which has a semi-permeable membrane 128 affixed to its bottom. The semi-permeable membrane 128 and the female component 10 can sit above a hole 130 in the surgical table pad 124, which can allow for air flow. Any other type of membrane or filter can be used (or none at all), and a hole 130 is not required.

(53) This application has been described with reference to several embodiments. Many modifications and alterations will occur to others upon reading and understanding the preceding specification. It is intended that the application be construed as including all such alterations and modifications in so far as they come within the scope of the appended claims or the equivalents of these claims.
