Abstract
Abstract A therapeutic pad is formed from a container having elongate compartments arranged in parallel relationship across the width of the container and extending substantially across the full length of the container. The container is formed from a fabric material which is permeable to moisture but contains the filler material which is sand. The compartments are filled with the sand. The use of sand allows moisture to be applied to the container which will then be held within the interstices of the sand for either heating by microwave or cooling by freezing. A separate cover is formed from a quilted padded fabric material shaped to double the size of the container so that it can be folded to cover both sides of the container. One half of the cover includes a moisture impermeable layer to prevent the escape of moisture from that side while the other side allows the escape of moisture. This allows the user choice of applying either moist heat or dry heat to the body of the patient.

Independent Claim
388 words
A therapy pad comprising a substantially planar container having two sides, a filler material received within the container, the container being formed from a flexible fabric material which is resistant to heating and freezing, is permeable to moisture and retains the filler material within the container, the container being formed into a plurality of separate elongate parallel tubular compartments each extending substantially wholly across a width of the sides of the container and the compartments being arranged in a row from one end of the sides of the container to an opposed end of the container with each compartment being separated from a next to allow flexing of the container about a line between the compartments, the filler material consisting substantially wholly of sand, and a cover for the container separate from the container and comprising a padded fabric body shaped to cover both sides of the container, the cover comprising a first side for engaging over and covering one of said sides of the container and a second side for engaging over and covering the other of said sides of the container, each of the sides of the cover having a shape and dimension substantially equal to that of the container, and the sides of the cover being connected along one common side edge such that the cover can be folded along said one common side edge, allowing the first and second sides to be opened into a flat panel and folded to an overlying condition to receive the container therebetween, the cover including fastening means for holding the first and second sides in the folded overlying condition, the cover being formed of a first layer of fabric, a first layer of padding attached to said first layer of fabric, a second layer of fabric, a second layer of padding attached to said second layer of fabric, said first layer of fabric and said first layer of padding being attached to said second layer of fabric and said second layer of padding with the first and second layers of padding facing inwardly toward each other, said first side only of the cover having within said padded fabric body thereof between said first and second layers of padding a layer substantially coextensive with said container which is impermeable to moisture and said second side being permeable to moisture.
