Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
228 words
A hemorrhoid relief cushion comprising a pressure-compensating fitting pad of a resilient, solid cellular composition capable of exerting a slight but effective pressure on hemorrhoids that counteracts the pressures applied to said hemorrhoids by veins in the vicinity of the anus of a user, said pad having an essentially rectangular outline including a pair of side edges free of cut-out portions and a contoured major surface, said contoured major surface including first and second elongated, continuously curved, convexly elevated portions, said first portion having a first elevational contour and being of relatively lesser size than said second portion and whose length extends transversely inwardly from adjacent the central portion of one of said side edges toward the other of said side edges, said second elongated, continuously curved, convexly elevated portion having a second elevational contour and being of relatively greater size that said first portion and whose length extends transversely inwarly from adjacent the central portion of the other of a said side edges toward said first elongated, continuously curved, convexly elevated portion, said first elongated, continuously curved, convexly elevated portion being constructed and arranged to relieve hemorrhoids within the creased of a first person having a relatively small crease and said second elongated, continuously curved, convexly elevated portion being constructed and arranged to relieve hemorrhoids within the crease of a second person having a relatively large crease.
Claim 2
Dependent Claim
