Therapeutic Pillow

According to the present invention a therapeutic pillow, for inducing a state of physiological relaxation, is formed from a substantially shape sustaining material and comprises an upwardly facing concave supporting surface formed by four component surfaces which are separated by a cruciform shaped recess.

When a patient lies with his head on the supporting surface of the pillow the cruciform shaped recess permits some relative movement between the four component surfaces to accommodate craniosacral movement of the occiput bone at the back of the skull and its attendant membranes and muscles to induce a state of physiological relaxation.

Four component surfaces are used to correspond to the structure at the rear of the scull to provide greatest relaxation.

The base of the pillow may comprise a two dimensional or three dimensional downwardly facing convex surface to act as a rocker to allow movement of the occiput bone in craniosacral motion and the head as a whole in movement produced by the act of respiration.

In its simplest form, the pillow may comprise a block of material with a concave upwardly facing surface and a cruciform shaped recess formed therein. However, preferably the pillow comprises a rigid base, with four softer pads projecting therefrom to provide the component surfaces. The base may be of any suitable material such as wood, sprung steel or plastics, such as polyurethane or polystyrene weighted with a heavier material such as lead. The pads may be foam such as integrated polyurethane with a density of 70-90, or may be hollow and filled with pressurised air. The pads may have a cover of soft material or fabric such as leather. Each pad preferably has a Shore A scale hardness value of between 15 and 80, and more preferably between 35 and 40.

Preferably each of the component surfaces extends radially outwardly from the centre of the cruciform shaped recess and is convex in this direction, and at least the portion of each surface closest to the centre of the recess is concave in the circumferential direction of a circle centered on the centre of the recess.

In the accompanying drawings:

FIG. 1 is a perspective view of a pillow in accordance with the present invention;

FIG. 2 is a plan of the pillow shown in FIG. 1; and

FIG. 3 is a section taken along lines III--III in FIG. 2.

The therapeutic pillow shown in FIGS. 1 to 3 has an upwardly facing concave supporting surface 1 formed from four substantially quadrant shaped component surfaces 2 which are separated by a cruciform shaped recess 3. The pillow comprises a base 4 with a downwardly facing convex surface so that the pillow may rock to and fro or from side to side. The surfaces 2 are provided by four foam pads 5 fixed to the upper surface of the base 4. The pads 5 are covered with leather 6. The surfaces 2 are convex in a radial direction as shown in FIG. 3, and, towards the centre of the recess 3, concave in a circumferential direction.

In use a patient adopts a `Crook Lying` position, lying on his back with the back of his head resting on the supporting surface 1 of the pillow and with his hips and knees bent to a comfortable degree and supported by conventional pillows.
