Abstract

A portable patient supporting seat that is not only comfortable but also controls the spine support by correct pelvis positioning. Ischial turerosity (protuberances) support the users body while sitting and elevate the anus from the seated height. A first advantage of the present invention that is a modular pad, is to provide a build up that assists the body in supporting the anus externally and relieving the load on the sphincter muscle. By varying the configuration and modifying the dimensions relief of the ischial tuberosity and coccyx pressure is achieved. Adding a back support to the present invention allows better support for some patients suffering low back pain as well as providing a support insert that may be used in wheel-chairs as well as in automobiles. The modular structure of the present invention is to provide configuration components that are interchangeable, yet each configuration being self contained.

Dependent claims

In a patient support system comprising a seat having a seating surface between a back and a front edge including a substantially upright back rest the improvement comprising:

a planar base having top and bottom surfaces between a forward end and a rear end and two side edges, said base being sized such that said forward end and said rear end lie between the back and the forward edge of said seating surface;
and
support means mounted on said upper surface, said support means defining a support plane elevated above said top surface and extending from said forward end to a termination approximately halfway between said forward and rear ends to define a rear area of said base devoid of said support means, said termination characterized by a substantially steep transition from said support plane to said upper surface, so as to support the thighs of said patient while seated on said seat above said upper surface of said base board while the buttocks are supported directly on said rear area of said base, whereby the user's pelvis is tilted in one direction with attendant correction in spinal column posture,
said base being reversible on the seat for positioning said support means under the buttocks of the user while the knees are unsupported by said support means at the forward edge of the seat whereby the user's pelvis is tilted in an opposite direction with a corresponding correction in spinal column posture.
