The prone positioning device supports the head, neck and upper torso of a person in a prone position. The device is typically utilized to support a patient during a medical procedure. Without a device to support a patient in the prone position during a medical procedure, the medical personnel will have to create a temporary support for the patient using materials such as towels, pillows or other items at hand. Such ad hoc supports are not optimal because they may support the patient in an uncomfortable position, may injure the patient through insufficient support, may not provide firm enough support to hold the patient in a fixed position during the procedure, and may not allow the medical personnel to see or have access to the patient's face during surgery. In particular, the inability to see or access the patient's face during surgery inhibits the medical personnel from monitoring the patient and the lines and tubes that may be inserted through the patient's nose and mouth.

The invention described herein supports the patient in the prone position while allowing medical personnel to monitor the patient's face and the lines and tubes inserted into the patient's nose and mouth. The medical personnel are able to monitor the patient without altering the patient's position or moving the support device.

Referring now to FIG. 1 , a perspective view of an embodiment of the prone positioning device is depicted disposed on a surgical table. The embodiment of the device 100 is shown on a table 102 with the outline of a patient 104 supported on the device. As can be seen the device 100 supports the upper chest, neck and head of the patient 104 in the prone position. The device 100 is typically formed from one or more types of foam to provide firm but comfortable support to the patient. The foam or other material may be covered with an outer skin to resist fluids and wear to the material, or it may be exposed material as appropriate for the application. The device may be produced in one or more sizes designed to fit a variety of sizes of patient, from children to adults of various sizes. The device 100 may be contoured to fit to the body of the patient, and to firmly but comfortably support the patient in position for the medical procedure.

Referring now to FIG. 2 , a perspective view of an embodiment of the prone positioning device is depicted. The depicted embodiment comprises a chest cushion 200 for supporting the chest and shoulders of the patient 104 . The chest ramp 200 transitions from the level of the surgical table 102 to the raised level of the facial support 202 . This transitional ramp provides support to the patient's body and holds it in a comfortable and safe position during a medical procedure. In the depicted embodiment, the chest cushion 200 and facial cushion 202 are surrounded by bolster 204 which generally conforms to the shape of the patient's body and holds it in the desired position by preventing lateral movement.

The patient's facial area is located over an aperture 206 allowing it to be seen from below and also allowing diagnostic, monitoring and life support equipment to be provided to the patient through the face, mouth and nose. The aperture depicted in FIG. 2 is generally T-shaped when viewed from above, to allow both of the patient's eyes to be visible through the aperture 206 , having a lateral section and a transverse section disposed substantially perpendicular thereto. In addition the patient's nose, and potentially its mouth are also visible through the aperture 206 . As will be described in relation to later figures, the patient can see down through aperture 206 into a cavity in the prone positioning device 100 . A mirror or other reflective surface placed in the cavity allows medical personnel to view the patient's eyes and facial area through the cavity and the aperture 206 .

Referring now to FIG. 3 , a top view of an embodiment of the prone positioning device is depicted. The chest cushion 200 and the facial cushion 202 may be provided with recesses and raised areas designed to contour to the patient's body. In the depicted embodiment the chest cushion is provided with recessed area 300 to contour to the patient's chest, and raised areas 302 and 304 for the patient's shoulder and neck areas. Similarly, facial support 206 is provided with recessed area 306 to conform to the user's chin, cheeks and forehead. The chest cushion 200 and facial support area 202 are surrounded by bolster 204 .

Dashed lines depict a cavity 308 and mirror 310 disposed beneath the patient's face. Cavity 308 is connected to aperture 206 so that the patient looks down into cavity 308 when supported on the device in a prone position. The mirror 310 is disposed at an angle within cavity 308 to reflect light from the aperture 206 out through aperture 312 in the side of the device 100 . When a patient is disposed on the device 100 , medical personnel may look in through aperture 312 and inspect the patient's face through aperture 206 .

Referring now to FIG. 4 , a side view of an embodiment of the prone positioning device is depicted. Bolster 204 parallels chest cushion 200 and slopes upward to the facial cushion 206 . An aperture 312 is provided in the lower portion of facial cushion 206 to allow medical personnel to see into cavity 308 .

Referring now to FIG. 5 , an end view of an embodiment of the prone positioning device is depicted. The base of the depicted embodiment of the device 100 is substantially wider than the upper surface to provide stability, although this may not be necessary in all embodiments of the invention.

Aperture 312 is provided in the end of the device 100 adjacent to the patient's face. The aperture allows medical personnel to see into cavity 308 disposed beneath the patient's face. Mirror 310 is disposed within the cavity 308 at an angle so that the medical personnel looking in through aperture 312 may see the patient's face in the mirror 308 through aperture 206 . Tubes, lines and other medical equipment may be disposed through aperture 312 , cavity 308 and aperture 206 to be inserted into the patient's nose or mouth.

Referring now to FIG. 6 , a cross-sectional view of an embodiment of the prone positioning device is depicted. The patient's shoulders and chest rest on chest cushion 200 and bolster 204 extends above cushion 200 to provide a side wall and to help maintain the patient 104 on device 100 in the proper position.

Beneath facial cushion 202 aperture 206 extends downwardly to cavity 308 . Inside cavity 308 surface 600 is disposed at an angle that slopes downwardly toward the aperture 312 at the end of the device 100 adjacent to the patient's head. Mirror or reflective surface 310 is disposed on surface 600 . The angle of ramp 600 is such that the patient's face may be viewed by medical personnel through aperture 312 .

Referring now to FIG. 7 , a cross-sectional view of an alternative embodiment of the prone positioning device is depicted. The alternative embodiment does not include the chest cushion 200 . In some surgical table designs it may not be preferable or necessary to provide the chest cushion 200 . The embodiment includes the same facial cushion 202 and aperture 206 . The mirror 310 is similarly disposed in cavity 308 for the viewing of the patient's face through aperture 312 during a medical procedure.

Referring now to FIG. 8 , an exploded perspective view of a second alternative embodiment of the prone positioning device is depicted. In the depicted embodiment, the device is comprised of three parts which may be disconnected from each other, namely the chest support or cushion 800 , the facial support or support 802 and wedge-shaped component 804 . The components are removeably attached to each other by various means such as hook and loop fasteners, double-sided tapes, or other suitable adhesives. In the depicted embodiment, hook and loop material 806 is affixed to each component to attach the components together. This embodiment does not include the bolster provided in the previous embodiment.

Chest cushion 800 has a base and side cushions or walls 818 that generally increase in height from a first end 808 of cushion 800 to the second end 810 thereof. The cushion 800 provides a comfortable transition area supporting a patient with its abdomen on the surgical table and its head on facial support 802 . The patient's shoulders may rest on side cushions 818 with their chest in the recessed area between the side cushions 818 . Alternatively, the patient's chest and shoulders may fit within the recessed area between the side cushions 818 .

The facial support 802 may be provided with a top layer or cushion 812 that provides softer support to the patient's face than the material used for the remainder of the support 802 . This top layer provides for more comfort to the patient while the remainder of the support 802 holds the patient's head in the desired position and maintains the open access and sightlines to the patient's face through aperture 206 . In the depicted embodiment, the facial support 802 has aperture 312 for viewing of the patient's face on the reflective surface on platform 804 . It also has apertures 816 extending from the cavity formed by the apertures 312 and 206 to each side of support 802 . These apertures provide additional light and access to the patient's face for the purposes described herein.

Wedge-shaped component 804 is provided with a reflective surface or mirror attached or disposed on the angled surface 814 to allow viewing of the patient's face. Attachment material 806 is provided on a top surface of component 804 to releasably attach the component 804 to the bottom of support 802 .

Referring now to FIG. 9 , a bottom perspective view of an alternative embodiment of the prone positioning device is depicted. The components are depicted as attached together in the configuration for use with a patient. Support 802 incorporates a cavity for receiving wedge 804 beneath aperture 206 . As can be seen in FIG. 9 , the various apertures and layers in support 802 may be formed by attaching blocks of cushion material, cut to the appropriate shape, to each other to form the desired cushion. For example, in the depicted configuration, support 802 is formed of top layer 812 , support layer 900 , and feet 902 . Since top layer 812 and layer 900 are uniform in thickness, the outline of each piece may be cut from a sheet of the appropriate material and then joined to each other. Similarly, feet 902 may be cut from sheet material and then attached to the bottom of support layer 900 . This provides for a simpler cutting process then forming the final shape of layer 900 and feet 902 from a single block of material. Wedge component is disposed between two of the feet 902 and attached to the bottom of support layer 900 , with the angled upper surface directed toward aperture 312 .
