Abstract

A head rest accessory for coupling to a frame member at a head end of a pivotable torso support section of a hospital bed is provided. A frame is configured to couple to the frame member. A head rest mount is coupled to the frame and is repositionable along the frame. A head rest is coupled to the head rest mount and includes a face rest shell. A first angle sensor is positioned along a side of the face rest shell. A second angle sensor is positioned on a head end of the face rest shell.

First claim

The invention claimed is:

1. A head rest accessory for coupling to a frame member at a head end of a pivotable torso support section of a hospital bed, the head rest accessory comprising
a frame having a pair of rails that are spaced apart and substantially parallel and that extend from a distal end to a proximal end, a crossbeam coupled to the distal ends of the pair of rails, a U-shaped connector that is coupled to the proximal ends of a respective rail of the pair of rails, the U-shaped connector opening downwardly to permit the U-shaped connector to be insertable downwardly over the frame member to couple the frame to the pivotable torso support section so that the frame is cantilevered from the frame member,
a head rest mount coupled to the frame and extending between the pair of rails, the head rest mount having at least one releasable clamp that grips a corresponding one of the pair of rails to lock the head rest mount in place on the frame when the releasable clamp is in a locked condition, and the head rest mount being repositionable along the pair of rails when the releasable clamp is in an unlocked condition, and
a head rest coupled to the head rest mount, the head rest including a face rest shell having an upwardly facing concave surface and having a generally T-shaped cutout to receive a patient's eyes, nose, mouth, and a central chin region of the patient's face when the patient is in a prone position on the head rest accessory, wherein the generally T-shaped cutout includes a chin cutout including an open space configured to receive the patient's central chin region,
wherein the face shell includes a pair of cheek rests that flare inwardly to define a cheek rest opening between an inward most point of each of the cheek rests, wherein a cheek rest relief surface is formed in each cheek rest in communication with an eye cutout to facilitate distributing interface pressure from protruding facial features of the patient, wherein each cheek rest relief surface includes a concave surface having a radius of curvature that differs from a radius of curvature of the respective cheek rest,
wherein each of the pair of rails includes a loop configured to position over a base frame of the bed when the bed is in a Trendelenburg position, wherein:
the U-shaped connector includes a pair of sockets; and
each loop includes a post configured to be inserted into a respective socket, wherein the posts are removably inserted into each of the pair of sockets.

2. The head rest accessory of claim 1 , wherein the T-shaped cutout extends from an opening that defines the chin cutout to a mouth cutout having a width that is greater than a width of the chin cutout, wherein an inner edge of the T-shaped cutout flares inwardly between the chin cutout and the mouth cutout, wherein the T-shaped cutout extends from the mouth cutout to the eye cutout which has a width that is greater than the width of the mouth cutout, wherein the inner edge of the T-shaped cutout flares inwardly between the mouth cutout and the eye cutout.

3. The head rest accessory of claim 1 , wherein the crossbeam extends orthogonal to each of the pair of rails.

4. The head rest accessory of claim 1 , wherein the U-shaped connector extends perpendicular to the frame and includes a pair of flanges and a slot extending between the pair of flanges, wherein each of the pair of flanges includes a planar surface, wherein the slot is defined by the planar surfaces of the pair of flanges.

5. The head rest accessory of claim 1 , wherein each of the pair of rails has a rectangular cross-section taken in a vertical plane.

6. The head rest accessory of claim 1 , wherein at least a portion of the U-shaped connector includes at least one of a plastic and composite.

7. The head rest accessory of claim 1 , wherein the head rest mount is repositionable along the pair of rails along a longitudinal axis of the hospital bed.

8. The head rest accessory of claim 1 , wherein the head rest mount includes a base that is repositionable along the pair of rails.

9. The head rest accessory of claim 8 , wherein the base includes a track and a body repositionable along the track in a direction perpendicular to the longitudinal axis of the hospital bed.

10. The head rest accessory of claim 9 , further comprising:
a post extending vertically from the body, and
a mount rail extending from the post and repositionable vertically along the post,
wherein the head rest is coupled to a cantilevered end of the rail.

11. The head rest accessory of claim 10 , wherein:
the head rest is rotatable about the mount rail in a first rotational direction to roll the head rest,
the head rest is rotatable about the mount rail in a second rotational direction to pitch the head rest, and
the head rest is rotatable about the mount rail in a third rotational direction to yaw the head rest.

12. The head rest accessory of claim 1 , wherein the face rest shell includes:
a downwardly facing convex surface opposite the upwardly facing concave surface,
an outer perimeter having a partially circular top outer edge and a bottom outer edge, the outer perimeter including a pair of planar side outer edges extending between the top outer edge and the bottom outer edge, and
a bottom opening formed in the bottom outer edge, wherein the generally T-shaped cutout extends from the bottom opening, the generally T-shaped cutout defined by an inner edge, the generally T-shaped cutout including a mouth cutout extending from the opening and an eye cutout extending from the mouth cutout, wherein the eye cutout is defined by a planar top inner edge and a pair of curved inner edges extending from the planar top inner edge,
wherein the concave surface and the convex surface extend between the outer edge of the cutout and the outer perimeter.

13. The head rest accessory of claim 12 , wherein the face rest shell includes:
a top wall extending from the top outer edge, and
a pair of side walls, wherein each of the pair of side walls extends from one of the pair of planar side outer edges.

14. The head rest accessory of claim 13 , further comprising a face cushion is positioned on the concave surface of the face rest shell and retained in the concave surface of the face rest shell by the top wall and the pair of side walls.

15. The head rest accessory of claim 14 , wherein the face cushion includes a surface that is sized and shaped to the patient's face, wherein the face cushion includes a generally T-shaped cutout to receive a patient's eyes, nose, mouth, and a central chin region of the patient's face when the patient is in a prone position on the head rest accessory.

16. The head rest accessory of claim 1 , wherein the face rest shell includes at least one angle sensor attached to the face rest shell to indicate a tilt angle of the face rest shell.

17. The head rest accessory of claim 16 , wherein the at least one angle sensor is positioned along a side of the face rest shell and aligned with an eye cutout of the generally T-shaped cutout, wherein the at least one angle sensor measures a longitudinal tilt angle of the face rest shell.

18. The head rest accessory of claim 16 , wherein the at least one angle sensor is positioned on a head end of the face rest shell on a centerline of the face rest shell extending between the head end and a chin end of the face rest shell, wherein the at least one angle sensor measures a lateral tilt angle of the face rest shell.
