The present invention concerns a treatment plaster compris¬ ing an incorporated distancer that determines the distance between the area to be protected and the surface of said plaster.

It is already well known that the plasters used for protect¬ ing wounds, abrasions and similar from infection, even if having a layer of gauze or similar in that area being in contact with the wound, often prove to be difficult to re¬ move as it may get sticked to the wound due to phisiologi- cal humours, with painful consequencies for the patients and delays in the healing process.

Furthermore, through the aeration openings and the thickness of the gauze, usually there is not the sufficient quantity of air and therefore of oxygen requested for a prompt heal¬ ing.

It is the aim of the present invention to realiwe a treat¬ ment plaster that eliminates all above mentioned disadvanta¬ ges.

The aim set forth is reached according to the present inven¬ tion by means of a treatment plaster of known materials but comprising in that area that gets into contact with the wound usually covered only with the sterilized gauze, a distancer 4, consisting of a light structure provided with holes like a net out of materials like plastic, metal, card-

board or similar, for forming an inner volume below the pla¬ ster provided with holes, for the free air circulation.

The considerable advantage of the present invention consists in the perfect funcitoning of the plaster according to the present invention which even if not very encumbersom , as the thickness of the incorporated distancer is of a few mil¬ limeters, avoids any contact with the wound or similar and allows a considerable aeration -and keeps the internal area -protected from dust and atmospherical bacteria.

In a variant, in the area protected by the distancer the la¬ yer of sterilized gauze may be provided.

The present .invention will be described more in detail he- reinbelow relating to the enclosed drawings in which some preferred embodiments are shown.

Figure 1, shows an axonometric external view of the treat- ment plaster with incorporated distancer.

Figure 2, shows an exploded axonometric view of the parts forming the paster of the precedent figure.

Figure 3, shows a vertical section of the treatment plaster.

Figure 4, shows a variant of a distancer to be incorporated in a plaster.

Figure 5, shows a plant, a lateral and an axonometric view of a punched plaster that may be folded so as to delimit the area to be protected.

Figure 6, shows an exploded axonometric view of a variant with a distancer having the shape of a bull of foamy material.

Figure 7, shows a plant and a section view of a variant of a malleable distancer that may be applied follow¬ ing to a curve determined by a manual pressure, as it is shown in the lateral view of figure 8.

Relating to the details of the figures, the object of the present invention comprises a plaster 1 of any shape and dimension, provided with a cavity 2 outwardly turned with aeration holes 3, in which a distancer 4 is housed that will form a space 5 in correspondence with the wound or similar to be protected.

Said distancer 4 may be realized with a small net of pla¬ stic material like a parallelepiped structure, or also of different materials and different shapes.

In a variant, said distancer may consists, as shown in fi¬ gure 4, of a structure 6 being cylindric or ellipsoidal or rectangular or of any other shape, detached from the base and provided with aeration holes 7 which have the same function that the net of the precedent figures.

In a further variant shown in figure 5, the protection space 5 is obtained without particular rigid structures, but the form of the distancer is determined by the punch- ings-A-B-C-D performed during the realization of the sa- me plaster, so as to obtained, following to the folding and adhesion (D) of the support ribs of a 'wheathered' structure, that will appropriately prevent the contact with the protected area.

Said protection area 5, in a variant of cheap realiza¬ tion as shown in figure 6, consists of the inner space of the distancer in the shape of a bull, being paralle- piped or cylindric, out of foamy or rubber or expanded lastic materials, while the upper cover consists of the same structure of the plaster, with a layer of gauze or other disinfectant materials 9„

For what concerns the variant of figure 7, plaster 1 has the same structure as a usual one but has, out of one piece by realization, the layer of malleable mate¬ rial 10, that may be manually curved when used and remains in that shape so as to protect the underlying space 5.

Above mentioned distancers, of the net 4 Jcind or with holes 6, may usually be used also single for the pro¬ tection of wounds and similar, and may not need be in¬ serted into cavity 2 provided in said plaster, but

simply being placed onto the area to be protected and the¬ reto fixed with a traditional plaster.
