This invention relates generally to patient support surfaces, such as patient support tables, and compliant pads therefor, and more particularly to patient support surface compliant pads and protective covers therefor for protecting the compliant pad and surroundings against fluid contamination from a patient resting on the patient support table.
The need to provide and maintain a clean, contamination free, and often sterile environment in a medical arena is well established. Contamination, such as from patient fluids, including blood and urine, for example, is directly associated with the known risk of infection that can be caused by bacteria from such contamination in the medical arena. As such, it is known that in order to minimize the risk of infection during a medical procedure, it is necessary to prevent the transfer of bacteria via contamination within the medical arena. Although the risks of infection during medical procedures are recognized, it remains a challenge to prevent the onset thereof, particularly with the challenges faced in preventing the contamination of surfaces, including patient support surfaces (table tops of patient support tables, including surgical tables and tables used in various forms of medical procedures, such as a urological procedure, for example) and compliant patient support pads thereon by patient fluids, such as blood and/or urine. Infections are estimated to affect upwards of 2 million patients or more annually. Aside from the complications brought about by infections, the infections create an economic burden on hospitals. For example, some studies have estimated that each bloodstream infection in a patient results in an average cost of $26,839 to the hospital. Accordingly, advances are needed to reduce the potential of contamination within the medical arena and infection resulting therefrom.
There is no single accepted methodology for covering table surfaces and/or compliant patient support pads thereon to protect against contamination, but most often flat sheets of plastic, known as “half sheets,” are simply draped over the surface to be protected. Of course, if the half sheets are not properly deployed, then the sterility of the underlying surface and medical arena is compromised, and thus, the potential for onset of infection in the patient increases. Further, if the surface on which the patient is lying is moved, even if the surface is initially draped properly, there remains an associated risk that the current draping mechanisms will become displaced, thereby exposing surroundings against contamination. Further yet, even if the current draping remains in place, there remains a risk that contaminants, such as blood and/or urine, can freely fall or flow onto and over an edge of the support surface onto an underlying, unprotected surface. Accordingly, a need exists for an improved protective drape and method of establishing and maintaining sterility in a medical arena, particularly for use with patient support surfaces and compliant patient support pads therefor.
A cover configured to protect a compliant pad on a patient support surface to prevent contamination from contacting the compliant pad, the patient support surface, and an area surrounding the patient support surface, is provided. The cover has a flexible upper wall with opposite sides extending lengthwise between opposite ends. At least one fluid collection funnel extends from at least one of the opposite ends. At least one fixation member extends adjacent at least one of the opposite ends, with the fixation member being configured to releasably fix the flexible upper wall to at least one of the compliant pad and the patient support surface.
In accordance with another aspect of the disclosure, the at least one fixation member can be formed from the same type of material as the flexible upper wall.
In accordance with another aspect of the disclosure, the at least one fixation member can include a bottom wall fixed to the upper wall, with the bottom wall and the upper wall forming a pocket having an opening sized for receipt of an end of the compliant pad into the pocket.
In accordance with another aspect of the disclosure, the bottom wall of the fixation member can be provided having a plurality of openings configured to facilitate attachment of the compliant pad directly to the patient support surface.
In accordance with another aspect of the disclosure, the at least one fluid collection funnel can be formed from the same type of material as the flexible upper wall, thereby simplifying and rendering the manufacture of the cover economical.
In accordance with another aspect of the disclosure, the at least one fluid collection funnel can include a pair of fluid collection funnels, with one of the pair of fluid collection funnels extending from one of the opposite ends and the other of the pair of fluid collection funnels extending from the other of the opposite ends, thereby assuring the containment of fluid and preventing contaminating of the surroundings of the patient support surface along opposite ends of the patient support surface, particularly if the patient support surface is tilted both fore and aft during a medical procedure.

In accordance with another aspect of the disclosure, the pair of fluid collection funnels can be formed from the same type of material as the flexible upper wall, thereby simplifying and rendering the manufacture of the cover economical.
In accordance with another aspect of the disclosure, the pair of fluid collection funnels can be formed as a monolithic piece of material with the flexible upper wall, thereby further simplifying and rendering the manufacture of the cover economical.
In accordance with another aspect of the disclosure, each of the pair of fluid collection funnels can be provided to extend from a proximal end, fixed to the flexible upper wall, to a free distal end, with at least one of the pair of fluid collection funnels being configured to channel fluid to a drain tube coupled to the distal end of the at least one fluid collection funnel. Accordingly, the at least one fluid collection funnel having the drain tube coupled thereto does not need to be sized to contain all the fluid flowing therein, as the fluid is free to flow in a controlled manner through the drain tube to a desired location, such as a fluid basin.
In accordance with another aspect of the disclosure, a filter member can be disposed between the proximal end and the free distal end of the at least one fluid collection funnel, with the filter member being configured to allow the flow of fluid therethrough and to inhibit the flow of solid matter therethrough.

The fluid collection funnel 28 extends from a proximal end 46, fixed to the flexible upper wall 18, to a free distal end 48. The fluid collection funnel 28 is configured to contain and channel fluid in a controlled manner to avoid contamination of the surrounding environment E. In one exemplary embodiment, the fluid collection funnel 28 is configured to channel fluid to a drain tube 50 coupled to the distal end 48, such as via any suitable tube connector 52, which can be fixed to the distal end 48, such as via an adhesive, weld joint, tape, or otherwise, if desired. The fluid collection funnel 28 can be formed of the same material as used for the upper wall 18, including, by way of example and without limitation, as being formed as a monolithic piece of material with flexible wall 18. Otherwise, if not formed as a monolithic piece of material with the upper wall 18, the fluid collection funnel 28 can be fixed along a portion of the proximal end 46 to the second end 26 of the upper wall, such as via an adhesive, weld joint, tape, or otherwise, as desired.
The fluid collection funnel 28 can include an integral (contained in) fluid filter member 54. The filter member 54 can be disposed between the proximal end 46 and the free distal end 48, wherein the filter member 54 is configured to allow the free flow of fluid therethrough and to inhibit the flow of solid, particulate matter therethrough or thereby. Accordingly, any solid particulate flowing into the fluid collection funnel 28 can be contained therein, thereby preventing the solid particulate from causing a clog downstream, such as in the drain tube 50, while also allowing only the fluid to be collected downstream, if desired. This allows the volume of fluid to be measured, such as in a collection basin 61, if desired, to ensure an expected amount of fluid is accounted for, as will be understood by a person possessing ordinary skill in the art (POSA). The filter member 54 can be provided of any desired filtrate medium, depending on the level of filtering desired. An outer periphery of the filter member 54 can be fixed about an inner, circumferential periphery of the fluid collection funnel 28 via any suitable fixation mechanism, including an adhesive, weld joint, tape, or otherwise, with the filter member 54 extending across the fluid collection funnel 28. The filter member 54 could be provided as the same type of material as the fluid collection funnel 28 and/or upper wall 18, such as a flexible sheet of plastic having slits formed therein to allow the flow of fluid through the slits, while obstructing the flow of solid particulate therethrough, by way of example and without limitation.
The fluid collection funnel 28 includes a fixation member 56 (

The cover 110 has a flexible upper wall 118 with opposite sides 120, 122 extending lengthwise between opposite ends, with one end being referred to as a proximal or first end 124, and the other end being referred to as a distal end or second end 126. A fluid collection funnel 128 extends from at least one of the ends, shown as extending from the second end 126, and at least one fixation member 130 extends adjacent at least one of the ends, shown as adjacent end 124, wherein the fixation member 130 is configured to releasably fix the flexible upper wall 118 directly to at least one of the compliant pad 12 and the patient support surface 14, as discussed above for the cover 10.
In lieu of the side flaps 62 and fluid barriers 64 discussed above for the cover 10, the cover 110 can be provided having a fluid collection channel 70 extending along each of the opposite sides 120, 122. The fluid collection channels 70 can be configured to channel fluid to the fluid collection funnel 128, thereby acting to prevent the flow of fluid over the side edges of the patient support surface 14, as discussed above for the fluid barriers 64. The fluid collection channels 70 can be formed of the same material used to form the upper wall 118, wherein the collection channels 70 can be formed as folded flaps of the upper wall material, thereby rendering the fluid collection channels 70 a monolithic piece of material with the upper wall 118. In essence, the fluid collection channels 70 serve as gutters, much like eaves troughs, to direct the flow of fluid to the fluid collection funnel 128. Accordingly, the cover 110 functions to contain and direct the flow of fluid, such as to and through a drain tube 150, as discussed above for the cover 10. Other than the fluid collection channels 70 discussed and illustrated, the cover 110 can be constructed in similar or the same fashion as discussed above for the cover 10, and thus, no further discussion is believed necessary.
