PATIENT POSITIONING DEVICE

BACKGROUND ART

1. Field of the Invention

The present invention generally relates to medical safety devices and more particularly to patient positioning devices including wrapped engagements for the arms and legs of patient usable for transport and surgical procedures.

2. Description of Related Art

The transfer of a patient from one support platform to another is a difficult procedure for hospital staff. In a hospital setting, patients are constantly being moved. For example, a patient entering the hospital via ambulance is moved from the medical stretcher or ambulance gurney to a hospital gurney, a fixed hospital bed, an examination table, or an operating table. Also, patients already in a hospital need to be moved as well. For example, a patient having surgery may be moved from a fixed hospital bed to a hospital gurney then to an operating table and finally back to a fixed hospital bed. Each time a patient is moved a sliding or lateral movement of the patient from one support surface to another is required.

Difficulties for patients and hospital staff may arise from this lateral transferring of patients. Typically, the hospital staff acting in concert is responsible to position and move the patient to the new support surface by means of lifting, sliding or dragging. This action may cause injury to the patient if the patient accidently slides off of the support surface or if the patient is dropped. Also, intravenous lines, monitor cables, and other components attached to the patient may become kinked, bound, pulled from or around the patient, or dislodged. Further still, the hospital staff may be injured from the act of lifting, sliding or dragging a heavy patient.

For most surgical procedures, the patient is placed on the operating table with the patient's arms positioned at the patient's sides. The surgeon will typically stand adjacent to the patient's side and lean over the patient thus unintentionally leaning on the patient's arm. Many surgeries last several hours and the pressure of the surgeon's body on the patient's arm may cause damage to the patient's arm, wrist or hand. Similar pressures can be inadvertently applied to the patient's legs if the surgeon is operating at or near the lower portion of the patient's body. Such pressures can again cause damages to the patient's hips, legs, knees, ankles and feet.

Furthermore, leaning on the arms, hand, legs or feet of a patient for a long surgery may cause a restriction in blood flow as well as pressure on muscles and nerve tissue. Consequently, patients may awake from the procedure with sustained permanent damage to the muscles and/or nerves of the arm, hand, wrist, and/or lower extremities. Even if the surgeon doesn't lean on the patient's arm, the patient is at risk for nerve damage which may be caused from resting the arms or legs on a hard operating room surface for extended periods of time.

The prior art teaches various systems designed to move patients without actually lifting. These systems employ air rollers, pull straps and inflation as a means to drag patients to and from support surfaces. Many of these systems are intended for single- patient/single-use application, such that the device stays with the patient from the hospital bed to the operating room table. These existing systems are deficient in that they don't protect the patient from external pressures and forces and are not sufficiently suitable for safe patient transport in all circumstances.

It is known in the art that patients in a hospital setting may be agitated, intoxicated or confused (such as when emerging from anesthesia), and may cause unintentional self- harm such as rubbing eyes or pulling out the intravenous lines. The prior art teaches arm protector devices used during surgeries but these designs are constructed of rigid materials and are typically secured to the operating room table or gurney and are primarily applied as restraints rather than protection devices. Such devices keep the arms or legs restrained away from the body, exposing the patient to the potential for further injury if the body position is adjusted with the arms or legs remain restrained. Further, such restraints do not provide adequate protection from external pressures and forces that could otherwise cause physical trauma and nerve damage.

As a result of the aforementioned problems, the inventor herein has developed a specialized patient positioning device as described in U.S. Patent Application Nos. 13/153,432 and 13/259,734. These patent applications describe a patient positioning device provided to position, protect and secure a patient on a support surface (such as an operating room table) for transfer to another support surface or for preparation for surgery. The positioning device includes a sheet with a first and second flexible substrate coupled to the sheet' s top surface. The first and second flexible substrates may be padded and are configured to wrap around an adjacent arm of the patient creating a wrapped engagement. The wrapped engagement is configured to raise the patient's arm above the support surface and pads, protects, secures and elevates the arms from injury caused by pressure imparted thereon during surgery or transport. This positioning device may be lifted or slid from one support surface to another utilizing various straps on the sides of the device. Optionally, an inflatable support may be used with the device to aid when sliding or translating the device with the patient thereon. Additional embodiments include the use of wrapped engagements for the patient' s legs to pad, protect, and secure the legs of the patient during transport or operation. The present invention herein improves upon the significant advantages described in these two applications and provides additional features and benefits in order to comprise an integrated patient positioning device useful in a variety or circumstances to protect a patient and to assist in positioning and transporting a patient.

To that end, in addition to pressure and nerve injuries, hypothermia is a recognized and common occurrence for patients during surgery. Patients who develop hypothermia are at a greater risk for complications, including a greater chance of heart problems, higher rates of infection, increased blood loss and prolonged recovery. To counter this, medical personnel may cover the patient with blankets. Blankets are typically bulky, frequently unravel, and may fall off the patient during pre-surgery, surgery, post-surgery or transport. In lieu of or in combination with blankets, a forced warm air system, i.e. Bair-Hugger, might be utilized. These systems typically draw air from an outside source, such as force air warming device/machine, which is well known in the art and is commonly used in hospital and surgery. These types of devices infuse air of a pre-determined temperature in order to maintain the patient's temperature in the normal ranges during surgeries. These types of warming blankets are frequently additional devices to be placed on the patient in surgery while being prepared for surgery after induction of anesthesia during which is a very busy time for the operating room staff as well as for the anesthesiologist. Frequently, these types of warming blankets are not places on the patient until surgery already underway. The addition of these discrete warming blankets can add additional complications during a surgery procedure, increase bulk, and lead to cumbersome set up and break-down before and after surgery. Accordingly, the present invention sets out to improve on existing patient warming technologies.

Further, there is a need for an arm or leg padding system that can accommodate patients of varying sizes and shapes. Specifically, an arm-padding system which can be used to secure the patient's arms by the patient's torso with expandability to accommodate obese patients in various sizes is a practical necessity. Such a system also may be used to protect the patient from injury and to keep them warm in surgical cases where the patient is arranged in a variety of positions such as prone, lateral, Trendelenburg, lithotomy, or when the patient's arms are outstretched and placed on arm-boards that are 90° from the operating table. Accordingly, the present invention provides a variety of embodiments that address these various situations and provides for an enhanced patient positioning device that is safe and effective for both patient and hospital staff.

Other features and improvements to the patient positioning device are described herein which provide further security and protection for both patient and staff while also providing enhanced convenience and organization during patient transport, positioning, and procedures.

It is, therefore, to the effective resolution of the aforementioned problems and shortcomings of the prior art that the present invention is directed. However, in view of the patient positioning devices in existence at the time of the present invention, it was not obvious to those persons of ordinary skill in the pertinent art as to how the identified needs could be fulfilled in an advantageous manner.

DISCLOSURE OF INVENTION

Items and/or techniques described herein may provide one or more of the following capabilities. Injuries to both patient and hospital staff during transition between one support surface and another can be reduced or avoided. Secure transition of a patient during transfer between support surfaces can be provided. A secure means is provided to grip a patient transfer device. Further, in order to help prevent injuries to the hospital staff during such transitions of a patient, a patient positioning device provides means to evenly apportion an amount of weight a person lifting a patient will bear. A patient positioning device also protects the patient from injury during a surgical procedure by protecting the patient's arms from lying too long upon an operating table, and protecting the patient's arms from damage should a surgeon or other hospital staff member lean upon the patient's arm during the surgery.

Examples of a patient positioning device provide secure lifting means to help prevent dropping of the patient during a transfer or transition, and means to easily slide the patient to and from surfaces to thereby limit the amount of weight any one person supports during lateral transfer of the patient. Patient positioning devices are provided that are relatively inexpensive to help insure widespread use so as to help prevent injuries to all concerned.

Means are provided in form of buckles to secure the device to the surgical table to prevent patient from sliding. Means are provided to protect a patient's arm from pressure damage while in surgery, as well as provide the choice of protection for either one or both arms. Means are provided to protect a patient's arm while in surgery with the means adapted to be employed with existing medical equipment, such as patient transfer systems. Means are provided to attach a patient transfer device using multiple straps, in the form of hook-and-loop fasteners or a buckle, along both sides of a central section to secure the sheet on a support surface. Means are provided to restrain a patient's arm to the patient's body along with protecting the patient's arm while in surgery. Back and other injuries to the hospital staff from lifting a patient may be prevented by providing multiple handles for lifting and sliding a patient.

In some embodiments, the present invention is a patient positioning device, comprising a planar sheet having first and second side edges and first and second end edges having a top surface; the sheet configured for positioning of a patient thereon, the patient being supported by he top surface with the first and second side edges adjacent to arms of the patient; a first flexible substrate and a second flexible substrate each coupled to the sheet, each of the flexible substrates including at least a portion of additional padding. The first and second substrates are wrapped around an adjacent arm of the patient creating a wrapped engagement wherein the additional padding is located beneath the adjacent arm of the patient. The wrapped engagement protects the arms from injury caused by pressure imparted thereon during surgery or transport and holds the arms in an elevated position above the planar sheet and an underlying support surface wherein the elevated position prevents injury to the arm from the planar sheet and the underlying support surface. The patient lying on the planar sheet may be lifted by or slid with the planar sheet. The bottom surface of the device may comprise a low friction material. In some embodiments, the first and second substrates further include a split provided transversely across the substrates, the split allowing the substrates to accommodate arms of varying sizes and to allow for the routing of wires, cables, and combinations thereof.

In some embodiments the device includes a dual-sticky pad comprising a planar sheet of adhesive material having a first adhesive side and a second adhesive side wherein the dual-sticky pad is configured to be disposed between the patient and the patient positioning device to prevent the patient from sliding or slipping relative to the patient positioning device.

In some embodiments, one or more pockets may be located adjacent to an axillary region of the patient, the pockets configured to receive an axillary support to support the patient when positioned in a lateral decubitus position. Further, in some embodiments, the first and second substrates include one or more windows adapted to receive and pass through cables and wires and to provide access to the arms of the patient.

In some embodiments, a shoulder strap is provided, the shoulder strap comprising a

U-shaped sheet defining two strapping members wherein the shoulder strap is disposed beneath the shoulders of a patient whereby the strapping members are disposed over and around the shoulder and are removably secured to a respective wrapped engagement.

In other embodiments of the present invention, a patient positioning device comprises planar sheet having first and second side edges and first and second end edges having a top surface; the sheet configured for positioning of a patient thereon, the patient being supported by the top surface with the first and second side edges adjacent to arms of the patient; a secondary sheet removably attached to the planar sheet wherein the patient is disposed between the planar sheet and the secondary sheet; and wherein the planar sheet and secondary sheet form a cocoon around the patient such that the patient can be repositioned between a prone position and a supine position.

In the "cocoon" embodiment, a first flexible substrate and a second flexible substrate each coupled to the planar sheet wherein the first and second substrates are wrapped around an adjacent arm of the patient creating a wrapped engagement that protects and elevates the arms from an underlying support surface. Further, the planar sheet may be removably attached to the secondary sheet by one or more buckles.

In another embodiment, forced warm technology is provided. Thus, the patient positioning device includes a planar bladder having first and second side edges and first and second end edges having a top surface; the sheet configured for positioning of a patient thereon, the patient being supported by the top surface with the first and second side edges adjacent to arms of the patient; a first flexible substrate and a second flexible substrate each coupled to the sheet; one or more air inlets in flow communication with the planar bladder, the air inlets configured to be attached to an air source; a plurality of apertures disposed through the top surface of the bladder wherein air from the air inlets passes through the apertures. The first and second substrates are wrapped around an adjacent arm of the patient creating a wrapped engagement which protects the arms from injury caused by pressure imparted thereon during surgery or transport and holds the arms in an elevated position above the planar sheet and an underlying support surface wherein the elevated position prevents injury to the arm from the planar sheet and the underlying support surface. The air source provides forced warm out into the inlets and out of the apertures such that the air surrounds the patient. BRIEF DESCRIPTION OF DRAWINGS

MODES FOR CARRYING OUT THE INVENTION

A patient experiences a multitude of stages when undergoing surgery. Figure 1 is a flowchart of possible surgical events 100. The process starts in a pre-operative area. At step 102, the patient waits here before entering the operating room for surgery. Next, the patient is transferred into the operating room and at step 104, the pre-induction phase begins. The patient is placed on any necessary monitors such as blood pressure cuffs, Electrocardiography (EKG) electrodes, pulse oximeter, intravenous therapy (IV), or the like. At step 106, or induction, the patient is administered anesthesia for surgery.

At step 108, the patient is positioned for surgery. Depending on the type of surgery, the patient may be positioned in a prone, supine, lithotomy or lateral decubitus position. During this time the patient's body parts are often exposed to cold, ambient air normal in an operating room. Loss of body heat is a concern during the surgical process and the patient' s body may become hypothermic.

Hypothermia may occur during the surgical process. Under anesthesia there may be a loss of the behavioral response to cold and impairment of thermoregulatory heat- preserving mechanisms through the hypothalamus and autonomic nervous system. Anesthetics also cause peripheral vasodilation, causing redistribution of the blood volume with associated heat loss, leading to significant reduction of core temperature. In addition to this, patients may be exposed during their surgery, further accelerating heat loss, and may already have become cold during the inactive period waiting for surgery. With fluid deprivation, conventionally practiced for up to 6— >8 hours before general anesthesia, the patient may also become relatively dry and poorly perfused so that heat distribution by their circulation is further impaired. Finally, although steps may be taken to avoid it, un- warmed anesthetic gases and intravenous infusions may also add to the reduction of core temperature. At step 110, the patient is prepared for surgery: This involves preparing the patient's skin area for surgical incision by using an antiseptic solution to help reduce infection. Further heat loss from the patient's body may occur. Next, draping the patient occurs at step 112. During this stage, the patient's incision area is isolated and exposed for surgery, while the remainder of the body is typically covered with sterile drapes. These sterile drapes are normally made of thin polypropylene material providing minimal heat loss prevention while the primary purpose is to provide a sterile environment to reduce infection during the surgery.

At step 114, surgery starts. Depending on the procedure, surgery may be short or last several hours. Again, additional heat loss from the patient's body may occur. At step 116, surgery ends.

Clean up starts at step 118. The patient, sheets, coverings and instruments are cleaned and removed from soiling due to body fluids. At step 120, the patient begins to emerge from anesthesia and may be awaken by medical personnel. The patient is then moved to a transporting gurney at step 122 and transferred to a recovery room entering the post-operative area. At step 124, the patient further recovers from anesthesia.

As is evident, a patient undergoing an operation or other procedure will be moved, positioned, re-positioned and transported several time. Accordingly, the present invention provides a patient positioning device that can be used for moving and lifting a patient from one surface to another surface in a hospital setting. Examples of such a device are described that are adapted for easy lifting of a patient, to and from an operating table, which offers ease of use for lifting the patient and protection of the patient's arms and legs during surgery and transport. Figures 2 and 3 show one embodiment of the patient positioning device 10 of the present invention. A top surface 24 is positioned opposite the bottom surface 26. The top surface 24 and bottom surface 26 are formed of flexible fabric sheet and composed of center section 12, overhang sections 11, outer edge of center section 22 and outer edge of overhang sections 15. The center section 12 is of a rectangular geometry and adapted in length and width to accommodate the size and shape of a human being. Further, the center section 12 is sized to be laid on an operating room table which varies between, for example, 20-24 inches, or a stretcher or gurney with a width between, for example, 22-27 inches. Overhang sections 11 extend from the sides of center section 12. These overhang sections may be tucked under the mattress or pad on a gurney or table providing a means for the device 10 to operate in place of a bed sheet thus reducing germs and cost. Outer edge of center section 22 is a point of attachment for various components described hereafter.

Handles 14 are attached to outer edge of overhang sections 15 which allow for a safe grip on the device when used for lifting and pulling the device after the patient is secured. The quantity and orientation of handles 14 is not limited by the drawing as shown but is merely simplified for illustrative purposes.

The top and bottom surface, 24 and 26 respectively, may be of different material each of which is adapted for a specific purpose. The top surface 24 may be made of textile or paper reinforced with textile fabric, or another woven or knitted fabric adapted to the task of supporting a patient thereon. The bottom surface 26 of the device may have a surface configured to have low friction when the device 10, with patient aboard, is slid during a transition. The bottom surface 26 is composed of material which is slippery or has a low coefficient of friction, so as to allow the medical staff a means to easily slide the patient to and from a support surface. One example for a top surface 24 is a paper cloth or similar woven or knitted textile surface. The bottom surface which is exposed, may be formed of any low friction material as would occur to those skilled in the art including but not limited to one or a combination of materials from a group including PTFE impregnated or coated fabric, spunbond or other fabric when woven or formed has a slippery surface, or fabrics such as rip-stop or micro fiber-based materials woven or knitted from woven nylon, or polyester. The slippery bottom surface 26 may be sewn or laminated or coated to the device 10 or on the opposite side of the material forming the top surface 24 of the center section 12.

Referring to Figure 3, equipment straps 23 and pocket 21 are detailed. Equipment straps 23 are fastened to top surface 24 at one end and contain hook and loop fasteners. Directly under equipment straps 23, and coupled to top surface 24, is a group 42 of hook and loop fasteners. The equipment straps 23 are fastened to group 42. Pocket 21 is coupled to top surface 24 having one open end. Both equipment straps 23 and pocket 21 may be used to secure a medical device, an intravenous tube, a catheter tube and/or a piece of medical equipment that is attached directly to the patient.

Figures 2 and 3 also show two disengaged padded substrates 16 which are substantially planar. These padded substrates 16 are flexible and have an inner edge 17 that may be permanently fastened to center section 12 by sewing with durable thread or another suitable means, or temporarily fastened with a hook and loop fastener, such as Velcro® or other such removable fasteners. In one embodiment, padded substrates 16 are temporarily removed from device 10 so they may be employed on pre-existing patient transfer devices as described in the prior art which lack protection for the patient's arms.

Padded substrates 16 are positioned with respect to the top edge of the central area of the center section 12 at a distance comparable to the distance of a human arm, between the upper arm and hand, when placed to the side, to the human head. Preferably, padded substrates 16 have a layer of padding imbedded or engaged such that when engaged around the arm of a patient, a means to pad the arm is provided. This protects the patient's arm from any pressure forces imparted by the table or by a surgeon. Padded substrates 16 also are configured to engage around the arms of the patient, and hold them against their body and slightly elevated from the underlying table or support surface. This helps eliminate injury to the patient's arm when it is supported on a hard table surface for a long duration by placing a gap between the table and arm.

Referring to Figure 4, padded substrates 16 are shown attached at inner edge 17 to the center section 12. The back surface of padded substrates 16 have strips of hook and loop fasteners for securing. Straps 40 are also attached to the center section 12 at outer edge of center section 22 at one end. The bottom side of straps 40 have hook and loop fasteners for securing to padded substrates 16 when padded substrates 16 are wrapped around a patient's arm.

Optionally, device 10 may employ a permanent or removably engageable non-slip pad 28. The non-slip pad 28 will provide a means to prevent sliding when the patient is positioned on an angle. Also, in a one embodiment, foot securement restraint 13 is provided. The foot securement restraint 13 is coupled to top surface 24 and is wrapped around the legs of the patient and may be held by hook and loop fasteners. This foot securement restraint 13 enables the lower leg to remain positioned and secured during lifting or sliding of device 10.

In use, padded substrates 16 are employed to encircle and support a patient's arm when a patient lays on the center section 12 surface. This arm wrapping by the padded substrates 16 provide protection against the patient's arm moving outside the table area during fatigue and a potential pressure injury from contact with the underlying table or with a leaning surgeon while on an operating table. Figure 5 illustrates the device 10 with the patient 20 positioned with both arms encircled within padded substrates 16. Patient 20 is positioned on the patient positioning device 10 and straps 40 are employable to hold the flexible, padded substrates 16 in wrapped configuration around the patient's arms and maintain the arms close to their body and out of the way of the surgeon. The patient's arms may be held in this position by the straps 40 or using the overlap mode of the device (described hereafter, Figures 6 and 13). While arm is in said wrapped engagement, minimal movement of said arm is permitted. Foot securement restraint 13 is also engaged. The present invention positions and secures patient 20 during transfer preventing injury to the patient and hospital staff when dragging the device 10 by handles 14. Furthermore, the patient is now more easily transferable between one support surface to another, for example, a gurney to an operating table. The handles 14, engaged around the perimeter of the overhang sections 11 , provide personnel a secure grip while sliding or lifting a patient from one surface to another.

In an example embodiment of the invention, an overlap system may be employed to further secure and elevate the patient's arms. The overlap system employs flexible, rectangular overlap substrates 18 oriented lengthwise across the width of the center section 12 and attached at the centerline 19 as depicted in Figures 6 and 13. The bottom surface of the overlap substrates 18 have strips of hook and loop fasteners 44 which fasten to the hook and loop fasteners on the padded substrates 16 when engaged. The overlap substrates 18 provide a secondary means to secure the patient's arms and as noted and shown in Figures 11 and 12, the overlap substrates 18 are tucked under a pad or mattress.

Figure 6 shows the device 10 as optionally having a soft, foam pad 84 removably engaged to the top surface 24. This foam pad 84 is strategically placed in the buttock area to prevent pressure ulcers that may occur when a patient remains in the same position for an extended period of time such as during a long surgery or when a patient is confined to a hospital bed. Engagement may be by peel and stick adhesive or hook and loop fabric, or other means for removable engagement.

Figure 7 shows a view of the bottom surface 26 of the device 10. Belt 29 has connector 33 attached at the respective ends and is coupled to handles 14. This belt 29 and connector 33 secure device 10 to the support surface, for example, an operating table or bed. The quantity and orientation of belt 29 and connector 33 is not limited by the drawing as shown but is merely simplified for illustrative purposes.

The bottom surface 26 is constructed of a slippery fabric such as vinyl or Teflon coated fabric or another fabric which has a low coefficient of friction. The slippery fabric provides a means to aid in sliding the patient 20 in transitions. Also, a dotted line outline is depicted illustrating the position of an optional inflation support 30. This inflation support 30 is sandwiched between the top surface 24 and bottom surface 26 surfaces and when inflated, allows for an easier sliding of the patient 20. Figure 8 shows a cut through view of the device 10 ready for a patient 20 and to be placed in an as-used position as noted in the following figures, Figures 9-12. Figure 9 depicts an end view of the as-used position of an example of the device 10 prior to engagement of the padded arm restraints provided by the padded substrates 16. In use, the padded substrates 16 encircle the arm of the patient 20, and are then secured by straps 40 having hook and loop fasteners or other means of engagement.

Referring to Figure 10, the padded substrates 16 encircle the patient's arms and are secured by straps 40 which comfortably hold the patient's arms close to the body. Additionally, the arms are padded and protected from injury from laying on the support surface too long or from the pressure of the surgeon's weight. Also, with the padded substrates 16 so engaged, it provides a means to elevate the arms a distance "E" above the support surface. This helps prevent nerve damage and tissue damage caused by an arm sitting on a surface too long during surgery. Figures 11-12 show the engagement of overlap substrates 18 which may be wrapped over the patient's arms and tucked under the pad or mattress of the gurney or operating table. This provides secure positioning of the patient for surgery or transport. Figure 13 depicts another top surface view of one embodiment of the present device and Figure 14 shows the device with the padded substrates, overlap substrates is a disengaged position.

Figure 15 depicts another embodiment of the patient positioning device 10. A top surface 24 is positioned opposite a bottom surface 26. Top surface 24 and bottom surface 26 are formed of a flexible fabric sheet. A center section is of a rectangular geometry and adapted in length and width to accommodate the size and shape of a human being. A plurality of handles 14 are coupled to the outer edge of the sheet which allow for a safe grip on the device when used for lifting, pulling or moving the device while the patient is being supported by top surface and secured. The quantity and orientation of handles 14 is not limited by the figure as shown but is merely simplified for illustrative purposes. Bottom surface 26 which is exposed, may be formed of any low friction material as would occur to those skilled in the art including but not limited to one or a combination of materials from a group including PTFE impregnated or coated fabric, spunbond or other fabric when woven or formed has a slippery surface, or fabrics such as rip-stop or micro fiber-based materials woven or knitted from woven nylon, or polyester. The slippery bottom surface 26 may be sewn or laminated or coated to device 10 or on the opposite side of the material forming top surface 24.

Figure 15 also shows two disengaged padded substrates 16 which have a layer of padding imbedded or engaged such that when engaged around the arm of a patient, a means to pad the arm is provided. This protects the patient' s arm from any pressure forces imparted by the table or by a surgeon. Padded substrates 16 also are configured to engage around the arms of the patient, and hold them against their body and slightly elevated from the underlying table or support surface. This helps eliminate injury to the patient's arm when it is supported on a hard table surface for a long duration by placing a gap between the table and arm.

The back surfaces of padded substrates 16 have strips of hook and loop fasteners for securing. Straps 40 have hook and loop fasteners for securing to padded substrates 16 when padded substrates 16 are wrapped around a patient's arm. In an example embodiment of the invention, an overlap system may be employed to further secure and elevate the patient's arms. The overlap system employs a flexible, rectangular overlap substrate 18 oriented lengthwise across the width of top surface 24 and attached to top surface 24. The bottom surface of overlap substrate 18 has strips of hook and loop fasteners which fasten to the hook and loop fasteners on the padded substrates 16 when engaged. Overlap substrate 18 provides a secondary means to secure the patient's arms. The functionality here is substantially shown and described above in figures 9-12. Furthermore, in some embodiments, the device 10 includes a first and second flexible substrate forming legging 52 and legging 54.

Figure 16A depicts another embodiment of the patient positioning device. This embodiment is simpler than the embodiment of Figure 15 and focuses on the leg portion. A planar sheet has a first and second side edge and a top surface 24. This sheet is configured for positioning a patient thereon where the patient is supported by top surface 24 with the first and second side edges adjacent to the legs of the patient. A first and second flexible substrate capable of wrapping around an adjacent leg of a patient, thus creating a wrapped engagement, are detailed as legging 52 and legging 54. These wrapped engagements of the legs prevent heat loss during pre-surgery, surgery, post-surgery or transport and protect against pressure injury.

Legging 52 is mostly covered by legging 54 until it is engaged with the patient's leg. For example, more than 50%, 60%, 70%, 75%, 80%, 90% or 95% of legging 52 may be covered by legging 54. Referring to figures 15 and 16A, to use the patient positioning device in one embodiment, the patient is positioned on top surface 24. Optional padded substrates 16 are configured to engage around the arms of the patient, and hold them against their body and slightly elevated from the underlying table or support surface. This helps eliminate injury to the patient's arm when it is supported on a hard table surface for a long duration by placing a gap between the table and arm. Padded substrates 16 are wrapped around a patient's arms and secured with strips of hook and loop fasteners and straps as described above.

Legging 52 and legging 54 are configured to engage around the legs of the patient to protect the patient as well as prevent heat loss. Once the patient is positioned on top surface 24, the user would grasp and lift free edge 64 (see figure 16 A) of legging 54 wrapping this flexible substrate around, e.g., over and then under, the adjacent leg, creating a wrapped engagement (see figure 17). Fasteners such as hooks of a hook and loop (e.g., Velcro®) may be located on the underside of legging 52 and legging 54 at respective free edges 62 and 64 (see figure 3 A) while loops from a hook and loop fastener (e.g., Velcro®) may be located on the topside of legging 52 and legging 54 at respective attached outer edges 58 and 60 (see figure 3A).

Referring to figure 16A, the lower portion of top surface 24 is the area of attachment for legging 52 and legging 54. These are substantially planar and integral with the sheet and attached at a top edge 66 of legging 52 and legging 54 to top surface 24. Legging 52 is also attached at an outer edge 58 of top surface 24 while legging 54 is attached at an outer edge 60 of top surface 24. These attachment areas 68 may be continuous along the entire outer edge as shown in figure 16B or may be non-continuous as shown in figure 16C. Also, the attachments may be permanently attached such as by sewing, or temporarily attached such as by hook and loop fastener (e.g. Velcro®) allowing adjustability. In one embodiment, legging 52 and legging 54 may be constructed from a material that is perforated 70 and disposable. In this way, the leggings may be easily, conveniently and completely removed from top surface 24 and thrown away. Figure 16D illustrates this embodiment.

Figure 17 illustrates an embodiment of the present invention with a patient supported thereon. The patient positioning device 10 is utilized to position, protect and secure a patient on a support surface for transfer to another support surface or for preparation for surgery. In different embodiments, it may function as a regular bed sheet, a surgical bed sheet, leggings or any combination. To utilize the legging feature, after the patient is positioned and secured on the sheet, legging 52 and legging 54 may be engaged. To do this, an unattached edge, or free edge 64 of legging 54 is lifted and wrapped around, i.e., over and then under, the adjacent leg, and then fastened. Legging 52 is constructed in the same manner but using free edge 62 of legging 52.

Figure 18 illustrates another embodiment of the patient positioning device with the legging wrapped engagements. In this embodiment, legging 52 and legging 54 are loosely fitted on the legs of the patient. In this manner, any necessary medical devices such as leg compression devices, could be used when legging 52 and legging 54 are engaged.

With reference to Figure 19, to fasten legging 52 and legging 54, fasteners 56 such as hooks from a hook and loop fastener large or small (e.g., Velcro®) are located on the underside of legging 52 and legging 54 at respective free edges 62 and 64 while loops from a hook and loop fastener (e.g., Velcro®) are located on the topside of legging 52 and legging 54 at respective attached outer edges 58 and 60. Fasteners 56 are accessible when respective legging 52 and legging 54 are in the wrapped engagement with a respective leg. Figure 19 depicts an embodiment for fasteners for the patient positioning device showing a plurality of fasteners. The quantity and orientation of fasteners 56 is not limited by the figure as shown but is merely simplified for illustrative purposes. In one embodiment, fasteners 56 are non-continuous. This allows access to the leg of the patient for medical equipment such as cables and tubes or for monitoring.

The use of these leggings 52 and 54 is practical when the patient is in a lithotomy position (i.e. when the legs are placed in stirrups, see figure 20) thus involving the pelvis and lower abdomen such as during colon or genitourinary surgery. In some embodiments, legging 52 and legging 54 may be padded for protection from pressure injury that may occur due to the medical devices such as stirrups. Some studies have found a significant relationship between prolonged surgical procedures with the patient in the lithotomy position and a circulatory complication. This condition occurs when increased tissue pressure within a limited tissue space compromises the circulation and function of the contents of the space. Nerve injury to the femoral or peroneal nerve is also possible. Padding may be imbedded or engaged in the entire legging 52 and legging 54 or only in certain areas, such as in the area of contact to the knee joint, calf and/or ankle.

Figure 21 shows optional windows 72 on padded substrates 16. Windows 72 in the padded substrates 16, which wrap around a patient's arms, are created for the purpose of passing through medical lines such as blood pressure cuff tubing, pulse-oximeter cables, and/or intravenous lines. These windows are also used for viewing the patient's arm without having to unwrap padded substrates 16 from the patient's arms. In one embodiment, window 72 are openings in padded substrates 16. In another embodiment, window 72 consists of a flap of material attached permanently on one side. In yet a further embodiment, window 72 consists of a flap of material temporarily attached on one or more sides such as with hook/loop Velcro®. The number, configuration, and location of windows 72 may vary and the number shown in figure 21 is for illustration purposes.

It is appreciated that in some embodiments, the initial position of legging 52 and legging 54 before the wrapped engagement is flat to top surface 24 as shown in figure 15. Referring back to figure 15, the position of padded substrates 16 for the patient's arms, along with legging 52 and legging 54 for the patient's legs, may be adjustable by using attachment areas 68, for example, hook/loop Velcro® placement on top surface 24. This allows the device to accommodate a wide range of different patient sizes. Also, padded substrates 16 for the patient's arms may be perforated 74. In this way, the padded substrates 16 may be easily, conveniently and completely removed from top surface 24 for disposal should they become soiled or otherwise need to be disposed of.

In some embodiments, forced warm- air technology may be utilized with the present invention. This forced warm-air feature may utilized for the upper portion of the device to provide warmth to the upper extremities. In other embodiments, it may be used for the lower portion of the patient positioning device when configured with legging 52 and legging 54. In some embodiments, both upper and lower portions of the device may be provided with force warm-air features. With reference to Figures 22-23 shown is device 10 having forced warm-air capability. In some embodiments, the top and bottom surfaces 24 and 26 define a flexible bladder-type sheet which includes an inner space configured to receive forced warm air. In some embodiments, one or more warm-air inlets 80 are provided. As shown in Figure 22, a warm-air inlet 80 is provided at the upper portion as well as the lower portion 10 of the device. The inlet 80 is configured to receive a hose or tubing from a forced warm-air machine such as a compressor or the like that provides a warm air source. The top surface 24 of the device 10 includes a plurality of apertures 81 through which the warm air flows. The air flows into the inlets 80 and out of the apertures 81 thus providing warm air around all or a portion of the patient as shown in Figure 23. In the warm-air application, the bottom layer 26 which is made out of low friction nylon material or similar and is airproof and waterproof. The top layer 24 is preferably made out of Polypropylene material or similar for patient comfort. Through this top layer, a plurality of pinpoint holes 81 are created for warm air to escape and come into contact with the patient's skin as a means of warming the patient or maintaining the patient's temperature during surgery.

In other embodiments, the apertures 81 may be placed in legging 52 and legging 54 to allow forced warm-air to penetrate through the openings and onto the patient's skin. In this manner, using forced warm-air may warm the patient or may help maintain body temperature thus preventing hypothermia. Also, a blanket may no longer be required when using the device because legging 52 and legging 54 may provide the warming function.

With reference to Figures 24 and 25, in some embodiments, the padded substrates

16 are configured to conform to the arms of patients of various sizes and shapes. Figure 24 illustrates the device 10 with the patient positioned with both arms disposed above padded substrates 16 where the substrates are disengaged. In some embodiments, padded substrates 16 include additional padded sections 161 which are preferably aligned with the gravity dependant section of the patient's arms. In other words, the additional padded sections 161 are preferable disposed directly beneath the patient's arms, between the arm and the underlying support structure. With reference to Figure 25, the patient is positioned on the patient positioning device and straps are employable to hold the flexible, padded substrates 16 in wrapped configuration around the patient's arms and maintain the arms close to their body and out of the way of the surgeon. The patient's arms may be held in this position by the straps or using the overlap mode of the device (described above, Figures 6 and 14). While the arm is in the wrapped engagement using two straps 40, minimal movement of the arm is permitted. Further, the wrapped engagement is configured to elevate the arm or arms above the support surface to prevent pressure injury and nerve damage.

With reference again to figures 24 and 25, to further adapt the substrates 16 to a variety of sized and shaped arms, a split 401 is provided transversely across substrates 16 which birfurcate at least a portion of the substrates. In some embodiments, this split 401 allows the padded substrate 16 to conform around larger arms or an arm that may already be in a protective brace, splint, or cast. Further, the split 401 on the padded substrates 16 allow for the routing of wires, cables, and I.V. lines. In some embodiments, the wire, cable and I.V. lines can extend from the patient's hand/arm and be secured/organized between the padded substrate 16 and the overlap substrate 18. This will prevent the wire, cable and I.V lines from "hanging loose" at the side of the operating table and become detached or tangled. The split 401 in combination with the additional padded sections 161 provide additional comfort and security for both the patient and hospital workers.

During surgery, it is frequently necessary to change the operating table from flat to Trendelenburg position (head down) to optimize the surgical field for the surgeon to perform the necessary surgery, such as during surgery of the prostate, colon, or uterus/ovaries. Accordingly, with reference to figures 26-28, provided as an accessory to the patient positioning device 10 is a dual-sticky pad 841 to use in conjunction with patient positioning device 10 to help secure a patient during surgery while on a support surface to reduce sliding risk when changing positions from flat to Trendelenburg position (head- down) and vice versa. In some embodiments, the dual-sticky pad 841 comprises a generally planar sheet of adhesive material having a first adhesive side 842 and a second adhesive side 843. In some embodiments, a removable backing layer 844 is provided which protects the adhesive during storage. As shown in figure 27, the dual-sticky pad 841 is disposed between the patient 845 and the support surface 846. In some embodiments, the dual-sticky pad 841 is placed between the patient's back and the patient positioning device 10 such that they become a single unit. The unit can then be secured to the operating table using the belt 29 and connectors 33 shown in figure 7. Thus, the sticky pad 841 prevents the patient, on the device 10, from sliding when the operating table is changed from flat position (0 degree) to Trendelenburg position (head-down), which is shown in figure 28.

In yet another embodiment of the present invention, additional features are provided to secure and protect a patient who may be oriented in a prone, or face down position. With reference to figures 29-33, a modified patient positioning device 10 is provided, including padded substrates 16 for forming wrapped engagements around a patient's arms for protection and elevation, as well as the overlap substrate 18 for further securement and protection of the patient. One or more handles 14 are attached at the corners of the device 10. Further included are one or more buckles 900 which may be located proximal to the handles at the corners of the device 10. In conjunction with device 10 is a secondary sheet 901 shown in figure 30. Secondary sheet 901 is a substantially planar sheet and it some embodiments it matches the dimensions of patient positioning device 10. Secondary sheet 901 includes one or more handles 14 and one or more buckles 900, both disposed toward the corners of the sheet 901. The buckles 900 of the secondary sheet are located and configured to engage the buckles 900 of the device 10. In some embodiments, the buckles 900 of the secondary sheet 900 have male fittings while the buckles 900 of the device 10 have female fittings, allowing for a removable engagement thereof. In other embodiments the buckles 900 of the secondary sheet 900 have female fittings where those of the device 10 have male fittings. With reference to figure 31, a patient 902 is disposed with his back on the secondary sheet with the device 10 to be placed on his chest. Optionally, the patient's arms can secured by way of the padded substrates 16 and the overlay substrate 18 as described above. Then the secondary sheet 901 is secured to the device 10 by way of the buckle engagement 900/900 shown in figure 32. This configuration forms a "cocoon" around the patient as shown in figure 32 wherein the patient is sandwiched between device 10 and secondary sheet 901 with his arms secured by the wrapped engagements of the present invention. This arrangement provides significant protection and security for a patient who must be treated in a prone position as it draws the arms in, elevates them, and then surrounds the entire body is a secure cocoon that prevents dislodgement of the positioning device 10 during movement and repositioning of the patient. This will help secure all the arms/legs, IV access, Foley catheter and any other attachments together prior to positioning change from supine to prone or vice versa.

With this "cocooning", a true "log-roll" technique is provided to ease the process of positioning change as well as preventing injury to the anesthetized patient and the surgical team. For example, the patient, in supine position, has already been placed on the secondary sheet 901 on the gurney as shown in figure 31. The device 10 is then placed on top of the patient aligning the buckles 900 securing them together as shown in figure 32. The buckles 900 may have adjustable straps which can then be pulled for snug fit. The device 10 and secondary sheet 901 may be further secured using the Velcro attachments 903. After checking all the attachments, i.e. IV accesses, Foley catheter, the patient is ready to be repositioned to prone position. The gurney with the anesthetized patient is now placed side-by-side with the operating table for the repositioning. The whole surgical team must be present for this repositioning procedure as each person on the team is assigned a specific task to avoid injury to the anesthetized patient, i.e. the anesthesiologist to protect the patient breathing tube, face and neck, the surgeon to catch the patient during the turning of the patient, nurses to help lift the patient for the turning and protecting the legs as well as the multiple attachments on the patient such as IV accesses, EKG, blood pressure cuff/tubing, Foley catheter, etc. When everyone on the team is in position for the turning of the patient, communication is critical at this time. The anesthesiologist will call for attention and count to three. This is when everyone on the team together will turn the patient simultaneously.

After the turning of the patient, the secondary sheet 901 now can be detached by releasing the buckles 900 and Velcro attachments 903 from the device 10. It is important at this time to assure to avoid pressure on the critical organs of the patient's such as the eyes, nose, abdomen (for breathing), and the genital areas. The breathing tube must also be checked and again secured. All the pressured areas must be properly padded. At this point, the padded substrates 16 can be engaged to form wrapped engagements around the patient's arms and optionally the overlay substrate 18 can be engaged. At the end of the surgery, if the patient needs to be repositioned from prone to supine position, the process now can be reversed whereby the secondary sheet is reattached, the patient rolled back to a supine position whereby the device 10 can then be removed from the front of the patient.

In yet another embodiment of the device 10 of the present invention, structure may be provided to comfortably position a patient in a lateral orientation. As shown in figure 34, device 10 includes handles 14 and one or more rectangular pockets 701. Pockets 701, in some embodiments, are disposed toward the top of device 10 and are configured to align with the axillary line 700 of the device. This allows the pockets to be located proximal to the patient's armpits, or axillary region as shown in figure 35. The pockets 701 are adapted to receive a gel roll or a one liter fluid bag to be used as an axillary support 702 for the patient. In use, a patient is positioned on the top surface 24 of the device 10 aligning the pocket 701 with the "axillary roll" about one inch from the axilla of either side of the patient. After the patient is anesthetized, personnel are recruited to position the patient from the supine position to the lateral decubitus position with the axillary roll placed in the pocket 701 at the side that the patient will be positioned on, as shown in figure 36. For example, for right lateral decubitus, the axillary roll would be placed on the right pocket 701 prior to repositioning. The patient is then pulled to one side that is away from the "down" side and then rotated so that the operative side will be up and the decubitus side will be down. At this time the patient should be on the axillary roll to avoid pressure on the neurovascular bundle in the axilla (axillary nerve , artery and vein). At this time, fine adjustments should be performed to assure the patient is in the middle of the bed and secured to the operating room bed. The device 10 may further include the padded substrates 16 and overlap substrate 18 as provided throughout this disclosure. In yet another embodiment of the device 10 of the present invention, several additional features and functionality are provided. With reference to figures 37-38, shown is patient positioning device 10 having removable padded substrates 16 each have slits 401 as described above. The padded substrates 16 are attachable to the device 10 by way of hook and loop fasteners 371 provided on substrates 16 which engage corresponding hook and loop fasteners 372 on device 10. In some embodiments, the entire top surface of padded substrates 16 may comprise hook and loop fasteners 371. Thus, this embodiment removes the need for straps 40 in that the reverse side of the padded substrates 16 can include corresponding hook and loop strips 373 which allow the padded substrate 16 to be rolled over and doubled back on itself, securing and defining a wrapped engagement around a patient's arm or leg as shown in figure 38. Because the padded substrates 16 are removable from the device 10, they can be used as shown in figure 38 where the patient's arms are outstretched.

In some embodiments, a suction tip pocket 374 is provided to store the suction tip for the anesthesiologist. Next to this suction tip pocket is a side pocket 375 for kinking the suction tube to eliminate the annoying noise of the suctioning sound when the suction is not in use. hook/loop double-straps 376 may also be provided toward the top, middle, or bottom of device 10 to secure I.V. injection ports/arterial line/ Swan Ganz catheter/EKG cable/ or blood pressure tubing. The double strap design is necessary to keep the I.V. injection port between the straps to prevent sliding of the line. This same principle can be applied for Swan Ganz catheter or other lines. The double strap fasteners at the foot-end for the Foley catheter and chest tubes have additional loose Velcro strips with adhesive backing. These adhesive backing pieces are to be placed on the tube of the Foley catheter or chest tube. This is then placed in the hook/loop double-straps 376 to prevent the tube from sliding. Multiple loose hook/loop or Velcro strips can also be placed on the hook and loop surface 371 of the padded substrates 16 which serve to wrap the arms with the padded substrates 16 when they need to be placed on the arm boards shown in figure 38. They can also be used to organize the I.V. lines, cable, or tubes alongside the patient's arms.

To provide additional security and protection for the patient, a shoulder strapping system is also provided as an enhancement to patient positioning device 10. With reference to figures 39-41 shown is a shoulder strap 400 comprising a substantially planar sheet having a U-shaped cutout 401 thus defining two strapping members 402 and 403. Each side of shoulder strap 400 includes one or more hook/loop fasteners 404. With reference to Figure 41, the bottom portion 405 of the shoulder strap is configured to attach to corresponding hook/loop fasteners proximal to the shoulder area of the patient positioning device 10. The patient is then placed onto the device 10 and the strapping members 402 and 403 are carried over top of the patient' s shoulders whereby they each can be secured to the padded substrates 16 by one or more hook/loop fasteners 404. In some embodiments, the padded substrates 16 may have corresponding hook/loop fasteners 407. Further, in some embodiments, the shoulder strap 400 includes perforation lines 409 which allow a portion of the strapping members 402 and 403 to remain attached to device 10 while the remaining portion is carried over the patient's shoulder and attached to the padded substrates 16. Accordingly, the distal ends of the strapping members 402 and 403 may include smaller hook/loop fasteners on the inside of the perforation lines 409. The shoulder strap 400 provides additional structure to secure the patient's upper body and arms and further serves to protect and elevate the patient's arms from the underlying support surface, i.e. the operating room table or gurney.

The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
