Abstract
A hemorrhoid supporting pad, preferably associated with a seat cushion assembly, is formed from a flexible envelope partially filled with a fluid. The pad is positioned beneath a seated person. Portions of the envelope extend beneath the ischial tuberosities of the seated person, which causes the fluid in the envelope to flow into the central region of the envelope, where the fluid is forced upwardly beneath the anus to support the hemorrhoid.
Claims4
A hemorrhoid supporting cushion assembly comprising a supporting surface and a pad comprising:
- an envelope comprising an upper layer and a lower layer, said upper layer comprising a flexible material, said envelope being partially filled with a flowable fluid;
- said envelope being generally symmetrical about a longitudinal axis, and having lateral extensions which extend primarily under the ischia of a person seated on said pad without extending significantly outside of the ischia of the person, the width of said pad being approximately between 5 and 7 inches said pad being positioned on said supporting surface;
- said cushion assembly being positioned under said seated person, whereby the weight of said seated person causes fluid within the lateral extensions of said envelope to move predominently inwardly toward the central longitudinal axis of said envelope and to cause said fluid to move upwardly along said longitudinal axis to provide upward supporting pressure of about 60 millimeters of mercury to the anal area of said person.
