FR2574658A1 - Protective dressing of the adhesive dressing type - Google Patents

Abstract

The subject of the invention is a protective dressing of the adhesive dressing type comprising a recessed part 1 formed by a semi-rigid material such as polyethylene, polystyrene or polypropylene having a trapezoidal profile which allows extra height above the wound or other skin disorder and two quadrilateral parts which are flexible or elastic 2 and 2 bis coated with an adhesive product and provided with slots 3 and 3 bis into which the semi-rigid part 1 is inserted. The dressing will furthermore be able to comprise on its internal face a piece of gauze 3 filling the recess and intended to enter into contact with the epidermis or the wound. The dressing according to the invention is useful for protecting wounds or treating skin disorders.

Description

PROTECTIVE ADHESIVE DRESSING
The present invention relates to an adhesive dressing having in its central part a semi-rigid part preferably made of polymeric material, strong enough to allow a protective elevation above wounds or other skin conditions.

 The invention therefore relates to a means capable of limiting possible shocks which would otherwise risk directly reaching the injured or injured party.

 The dressing according to the invention is intended to be placed so that its flexible ends bear on one or two points located on either side of the area of the wound.

 The subject of the invention is specifically a bandage of the adhesive bandage type in the form of strips comprising a hollowed-out central part formed of a semi-rigid material having a trapezoidal profile allowing a heightening and two terminal tabs of quadrangular shape provided with slots in which the hollowed out central part is inserted.

 To ensure effective protection of the injured area, the central part of the dressing has an elevation of 2 to 5 mm approximately from the plane of the skin and at the terminal ends so that the wound is directly covered without the dressing resting on her.

 The two side faces of this trapezoidal part having a symmetrical inclination in order to absorb in the most effective way possible shocks or blows. It is also important that the protective central part is sufficiently flexible and resistant to perform this function.

 The upper face of the trapezoidal portion is flat or hemispherical in shape, or even in the shape of an ovoid dome so as to adapt as best as possible to the place to be protected.

 The invention may also include the use of a medicinal dressing or plasters which are applied directly to the skin and which are then covered with the protective adhesive dressing according to the invention.

 In addition, it appears desirable that the ends of the dressing intended to be fixed to the skin or to a plaster by means of an adhesive part attached to the underside of the support points and of any other suitable adhesion means are flexible. and flexible enough to adapt to body movement.

 This flexibility can be obtained either by gradually decreasing the thickness of the layer of adhesive plastic material, or by placing incisions or rectilinear notches in a portion of the adhesive part fixed to the skin. However, the first part of the support points of the central portion, located on either side of the recess, must be strong enough for possible shocks to be effectively absorbed.

 To maintain the adhesion to the required degree and for hygienic reasons, the adhesive layer of the part to be fixed on the skin will be covered with a thin protective layer, such as a plastic film or a piece of gauze. or other, dressing that will be removed before use.

 The protective hollow part, lends itself to the protection of all kinds of wounds or wounds, large or small. In each particular case, it suffices to choose a dressing, the hollowed out portion of which will have dimensions at least equal to those of the area to be protected.

 These examples are in no way limiting, and several variations and adaptations of this invention will be illustrated by the description below.

 Figure 1 shows a top view of a protective dressing, the two support points 2 may, as said above, be cut or incised from the ends to a sufficient depth, while ensuring that the resistance necessary is not diminished.

 Another variety of dressing according to the invention consists in that, on the inside face of the hollowed out part, a flexible gas or any other suitable kind of fabric 4 is fixed over the entire length of this face at skin level, intended to cover the injured part of the skin. The gauze and the hollowed out part thus form an integral protective assembly.

 FIG. 2 represents a profile view of the dressing according to the invention. We see the layer of gauze 4 covering the wound 5, as well as the support points 2 and 2a ensuring the fixing of the hollowed-out middle part as well as the ridges 3 and 3a ensuring the elasticity of the adhesive end parts 8 and 8 bis.

 The flanks 6 and 6a may further include incisions or pores 7 and 7a ensuring ventilation of the wound.

 Figure 3 shows another embodiment of the invention.

We can see a patch in top view. This plaster is provided with grooves 9 and 9 bis used to receive a hollowed-out part 6 and 6 bis protective devoid of gauze layer (4). To this end, the support points 2 and 2a are slightly shortened and adapted so as to allow their insertion by sliding in the grooves 9 and 9a under the effect of a lateral pressure exerted on the edges of the walls 6 and 6 bis. For this reason, it is important that the edges 6 and 6 bis of the recess have sufficient flexibility. To ensure solid fixing of the side walls 6 and 6a in the grooves 3 and 3a, there is provided on each side a notch with a width of about 1 mm, at their connection.

 In a preferred embodiment of the dressing according to the invention, the central raised part is made of polyethylene, polystyrene or any similar polymeric material having a similar elasticity and impact resistance.

Claims (7)

 1.- A protective dressing of the type of adhesive dressings, characterized in that it comprises a hollowed-out central part (1) formed of a semi-rigid material having a trapezoidal profile allowing an elevation above the wound and two legs ( 2 and 2a) at the ends of quadrangular shape provided with slots (3 and 3a) in which the central recessed part (1) is inserted.  2. A dressing according to claim 1, in which the hollowed-out central part (1) has a flat, hemispherical or dome-shaped upper face.  3. A dressing # according to claim 1, in which the hollowed-out central part (1) is inserted into at least two support slots (3 and 3a).  4. A dressing according to claim 1, further comprising on its underside a thin layer of plastic, gauze or other suitable material, capable of being removed before use.  5. A dressing according to claim 1, characterized in that the support points are shortened # and designed so as to be suitable for insertion by sliding in the grooves (3 and 3a), under the force of bilateral pressure which will be applied on both sides (6 and 6 bis) of the hollowed out part.  6. A dressing according to claim 1, characterized in that the hollowed out part is retained in the grooves (9 and 9a), thanks to the fact that after the forced introduction of the side walls of the cap in the grooves ( 3 and 3a), it is stressed by a force directed towards the outside, which blocks it securely in the grooves, and this also thanks to the presence of a rectilinear notch in the side walls (6 and 6a)  7. A dressing according to claim 1, characterized in that a flexible gauze or a suitable cloth is applied to the internal face of the hollowed out part extending at the level of the skin and covering the lesion.
