Abstract

A medical compress for hot or warm moist heat treatment. The compress is a multi-layered structure having a body of absorbent material sandwiched between a porous, liquid permeable layer and a liquid impermeable, heat-retentive layer, and a plurality of adhesive tabs disposed about the periphery of the compress. The heat-retentive layer maintains the compress at a desired temperature for the period of a treatment cycle. The compress is preferably biodegradable and microwavable to eliminate the bulky equipment now used in hydroculator therapy.

Claims

1. A medical compress for moist heat therapy comprising

a body of liquid absorbent material having an inside surface and an outside surface;

a layer of heat-retentive material disposed adjacent to the outside surface of said body of liquid absorbent material, said heat-retentive material extending over at least a portion of the outside surface of said body of liquid absorbent material; and

a layer of woven fabric disposed adjacent to the inside surface of said body of liquid absorbent material, said woven fabric extending over at least a portion of the inside surface of said body of liquid absorbent material,

said body of liquid absorbent material, said layer of heat-retentive material and said layer of woven fabric being sealed together at the respective peripheral edges thereof;

a plurality of attachment tab liners fixedly attached to the inside surface of said layer of woven fabric adjacent to respective attachment tabs; and

a plurality of attachment tabs having a first end fixedly attached to said layer of heat-retentive material and a second end extending from said layer of heat-retentive material, said second end of said attachment tab having an adhesive film disposed on the inside surface thereof the inside surface of said second end being selectively disposable in bearing contact with respective adjacently-disposed attachment tab liners.

2. A medical compress as described in claim 1 wherein said layer of heat-retentive material has a heat modulus sufficient to retain the compress at a desired temperature for a minimum of twenty minutes.

3. A medical compress as described in claim 1 wherein said layer of heat-retentive material is a liquid impermeable material.

4. A medical compress as described in claim 1 further including visual temperature indicia means disposed on said layer of heat-retentive material.

5. A medical compress for moist heat therapy comprising

a body of liquid absorbent material having a top surface and a bottom surface;

a layer of liquid impermeable, heat-retentive material disposed adjacent to the bottom surface of said body of liquid absorbent material, said layer of heat-retentive material extending over at least a portion of the bottom surface of said body of liquid absorbent material and having a heat modulus sufficient to retain the compress at a desired temperature for a minimum of twenty minutes;

a layer of soft, non-irritating and liquid permeable material disposed adjacent to the top surface of said body of liquid absorbent material, said liquid permeable material extending over at least a portion of the top surface of said body of liquid absorbent material,

the peripheral edges of the respective body of liquid absorbent material, layer of heat-retentive material and layer of liquid permeable material being sealed together;

a plurality of attachment tab liners fixedly attached to the top surface of said layer of liquid permeable material adjacent to respective attachment tabs; and

a plurality of attachment tabs corresponding in number to said attachment tab liners and disposed adjacent thereto, said attachment tabs having a first end fixedly attached to said layer of heat-retentive material and a second end freely disposed therefrom having adhesive means disposed thereon.

6. A medical compress as described in claim 5 further including visual temperature indicia means.

7. A medical compress as described in claim 6 wherein said layer of adsorbent material, said layer of heat-retentive material and said layer of liquid permeable material are biodegradable.

8. A medical compress as described in claim 7 wherein said compress is microwaveably without physical destruction of the several layers of material in the medical compress.

9. A medical compress as described in claim 8 wherein said attachment tabs are formed from non-allergic, breathing material.
