Abstract

A support cushion for a person in a lateral decubitus position, comprising a base, two lateral structural supports, and a central concavity, said lateral supports being sufficiently stiff to resist rolling of the person, said central concavity distributing a weight of the person. The support may be adapted for supporting the human flank above a surface, relieving pressure on an upper arm, and having comprising a structural bladder and a support cushion. The support cushion may be employed to limit a pressure on an upper arm and to maintain a patient in the lateral decubitus position during a surgical procedure.

Claims

1. A medical support system for adjustably supporting a torso of an immobilized anesthetized human in a lateral decubitus position above an operating table, said human torso having opposite lateral side surfaces, an anterior surface extending between the lateral side surfaces and a posterior surface extending between the lateral side surfaces, the support system comprising:

an inflatable pneumatic pillow having a front, a rear, opposed ends extending between the front and the rear, a substantially planar inferior surface extending continuously between the front, the rear and the ends for supporting disposition on the operating table, a plurality of substantially hollow air-filled support portions extending continuously between the ends of the pillow and disposed above the inferior surface, the hollow air-filled support portions being in air communication with one another and comprising an anterior support portion adjacent the front of the pillow, a posterior support portion adjacent the rear of the pillow and a lateral support portion between the anterior and posterior support portions, the support portions, in use, being configured such that the anterior support portion has a rearwardly and upwardly facing surface extending continuously between the ends of the pillow for supporting engagement of a portion of the torso adjacent the anterior surface and one of said lateral surfaces thereof, the lateral support portion has an upwardly facing concave surface extending continuously between the ends of the pillow for supporting engagement of a portion of said lateral surface of the torso, and the posterior support portion has an upwardly and forwardly facing surface extending continuously between the ends of the pillow for supporting a portion of the torso adjacent the posterior surface and said lateral surface, the anterior and posterior support portions both projecting upwardly from the inferior surface distances greater than the lateral support portion of the pillow; and

means for controlling inflation of said inflatable member for selectively raising and lowering the torso relative to the operating table, whereby the inflatable pillow avoids a high concentration of forces on portions of the human torso opposed to the operating table, whereby the anterior and posterior support portions resist rolling of the torso for maintaining the lateral decubitus position, and whereby the air communication between the support portions enables a distribution of forces on the torso.

2. The system of claim 1, further comprising a pressure gauge to determine a pressure in said inflatable member.

3. The system of claim 1, wherein the means for controlling inflation comprises a bulb pump for inflating said inflatable member.

4. The system of claim 1, wherein the inferior support surface defines a width extending in a direction between the front and rear of the pillow, the lateral support portion further defining a width extending in a direction between said medial and lateral support portions, the width of the inferior surface being approximately twice as great as the width of the lateral support portion.

5. The system of claim 1, further comprising a valve for adjusting inflation of said inflatable member.

6. The system of claim 5, wherein the valve comprises a pressure relief valve.
