PAD FoR MEDICINAL USE.
SPECIFICATION fOrming part Of Iietters Patent No. 673,630, dated May 7, 1901.
Application filed May 8, 1899. Serial No. 716,019. (No model.)-
To all whom, it may concern:
Be it known that I, FREDERICK W. WAR- NER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Pads for Medicinal Use; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, and tot the referencenumerals marked thereon.
My present invention relates to medicinal pads adapted to be used in the treatment of diseases by external or local applications to.
the body and one which may be filled with any absorbent or medicated material, and particularly to those which require for the best results to be heated or warmed before application to the body.
To this and other ends my invention consists in certain improvements, all as will be hereinafter described, and the novel features pointed out in the claims at the end of this specification.
In the drawing I have shown a perspective sectional view of a pad constructed in accordance with my invention.
The pad may be constructed of any desired size or shape, and its bottom or under side is formed from a piece of pliable refractory material 1, preferably a sheet of asbestos, having a lining 2 uponits inner side, and the top or cover 3 is made of cloth or other material. The edges of the pad are protected by a binding 4, and the parts are secured together by a line of stitching 5. The pad is adapted to be filled with any desired absorbent material or medicated compound, (indicated by 6,) which may be introduced between the lining 2 and top 3 through the opening left before the binding is entirely applied. I
When it is desired to use the pad, it may be heated quickly to the required'iemperature, the asbestos covering 1 on the bottom permitting the device to be laid upon the stove or held in contact with a gas-flame without burning until the whole is of sufficient -war1nth,when the pad may be applied locally,
the .top or cloth covering 3 being preferably prevents the radiation of the heat therefrom,
causing it to pass into the body.
Instead of employing the lining 3 on the inner side of the asbestos covering this might be dispensed with, if desired, and the absorbent material placed in direct contact with the covering 1; but I prefer to employ the lining 3, for the reason that the asbestos cardboard or cloth is liable to crack or break when bent sharply and is also liable to disintegration, and if the contents is not protected it is liable to leak'out.
While the pad is particularly adapted for containing an absorbent material, it is obvi ous that it could be :made to contain any other material which required to be heated or the efficiency of which would be increased by heating itsuch a filling, for instance, as a poultice, which might be introduced by the removal and subsequent refastening of the binding at one or more points.
I claim as my invention 1. A pad for medical treatment having on one side thereof a covering of flexible refractory material and on the other a covering of fibrous or woven material, and a suitable fill ing between them.
2. A pad adapted for treating the body by external and local applications, having a covering of flexible refractory material upon one side, and a covering of fibrous or woven material upon the other bound together at their edges and a filling material inclosed between them.- 7
3. A pad adapted for treating the body by external and local application'having a covering on one side of pervious fabric and upon the other side a lining of similar fabric and an outer coveringof flexible refractory material, and a filling material.
