COOL WET DRESSING WITH BANDAGES

Claim. (CI

The invention relates to improved wet dressings in the form of compresses covered with waterproof material as in the case of the well known Priessnitz dressing which consists of a moist covering over which a wrapping is placed and this 5 dressing then covered with an oil cloth or other sealing material and wherein the increased heat develops vapours from the moist cloth which are retained in order to produce a warming effect, or in the form of cool. Heretofore, these wet dress- 10 ings have been secured in place by means of initially dry bandages or cloths. While these prior bandages do desirably prevent the development of warm vapours, they have the disadvantage that the securing bandage gets wet and that the 15 dressing dries too quickly and loses its effect.

The primary object of the present invention is to provide a new type of cool wet dressing wherein, on the one hand, the development of warm vapours is prevented, and on the other ²⁰hand, the dry securing bandage is prevented from becoming wet through to a degree which irritates the patient.

This is accomplished by placing a perforated insert of waterproof material placed between the ²⁸dressing and the bandage and wherein the insert is thick enough to prevent the dressing from coming into contact with the securing bandage through the holes of the perforated insert. „„

This novel arrangement serves to prevent the securing bandage from being completely wet through. While the securing bandage may become wet to a certain extent, because of evaporation through the holes of the perforated insert, this wetting may be limited to such a small ex- ³⁵tent by a suitable size and number of the holes still sufficient to produce a cooling effect of the dressing that the securing bandage will not become wet enough to irritate the patient.

In order that the insert have the required ⁴⁰thickness without increasing its weight or its stiffness, it may be provided with an uneven surface by forming small hollow projections, ribs, grooves, or the like corrugations which serve to ._gadditionally separate the bandage from the dressing so as to assist in preventing the bandage from becoming wet.

In one form of the invention, the insert con. 128—156) sists of a rough fabric which is impregnated with a waterproofing substance so as not to fill up the meshes of the fabric.

One example of the invention is illustrated in the accompanying drawing in which:

Fig. 1 is a plan view of the insert: and

Figs. 2 and 3 are cross sections taken on the lines H—Π and III—ΠΙ of Fig. 1 respectively.

As will be seen in the drawing, the insert consists of a strip of the required width and of any desired length, formed by the pressing, rolling, or the like, of a homogeneous, non-absorbent, pliable, and sufficiently extensible material.

In the example illustrated, the surface of the insert is provided with ribs a so that, in spite of the small thickness of the material, the insert is of a considerable stoutness, and its weight is much less than that of a bandage of a corresponding thickness. Each rib is provided with perforations serving to conduct away the vapours developing in the wet dressing.
