United States Patent U.S. Cl. 128-156 Int. Cl. A611 15/06; A61m 31/00 5 Claims ABSTRACT OF THE DISCLOSURE An improved adhesive type bandage is provided in which the dressing portion to be placed in contact with the wound is an antiseptic material in filamentary form, preferably as a felted or non-woven mass. The preferred material is calcium alignate.

Antiseptic dressings are known which are constituted essentially by an adhesive tape, of which one part is intended to stick on the skin which another part is covered with a strip of textile material impregnated with an antiseptic product.

These adhesive dressings are convenient to use because of their instantaneous application, but their disadvantages are well known:

The antiseptic product only covers the textile fibres, generally of cotton, at their periphery, so that the textile strip can only retain a limited quantity of antiseptic product; furthermore, these non-resorbable textile fibres become incorporated in the wound and their removal is difficult, painful and causes bleeding.

The present invention has for its object an adhesive strip which does not have these drawbacks; it is applicable not only to the preparation of antiseptic dressings, but also to adhesive strips intended for various therapeutic treatments.

According to the invention, the therapeutic or antiseptic product is not used to impregnate a textile strip or other foreign vehicle; it is itself applied on a part of the adhesive tape in the form of solid filaments, preferably very fine, these filaments being advantageously bound to each other so as to form an aerated mass, for example carded in the same way as conventional cotton wool.

There is of course an advantage in providing the adhesive band according to the invention with protective strips of plastic material or of tarlatan intended to protect in known manner the adhesive portion of the tape and the strip of antiseptic or therapeutic product. In the same Way, the adhesive tape is preferably constituted by elastic fabric and may be provided with uniformly-distributed perforations.

The description which follows below, by way of example and without any limitation, will make it quite clear how the invention may be put into practice; it relates to an antiseptic and hemostatic adhesive dressing.

Calcium alginate is extruded in fine fibers of about 30 cm. in length which are then interlaced so as to form a homogeneous layer, the fibres of which cannot be separately detached.

In accordance with a first means, there is employed an ordinary carding machine which gives a layer of alginate wadding of 4 to 6 mm. in thickness, which is con- 3,431,907 Patented Mar. 11, 1969 ice solidated for cutting-up in two directions at right angles, 'by sticking it or sewing it on an intermediate supporting sheet which may be for example tarlatan or even an alginate fabric.

The sticking can be effected for example by means of a sodium alginate adhesive utilized either as it is or with the addition of calcium chloride so as to form in situ a highly adhesive film of calcium alginate.

The layer is then cut-up into rectangular pastilles which are stuck on the adhesive tape, for example by means of an adhesive with a base of latex. The thickness of the pastilles is reduced to about 2 mm. when they are compressed and covered with a protective strip of polyethylene or other plastic material.

According to another form of manufacture, there is employed an adjustable spinning card giving strips having a width adapted to the dimension of the dressing.

The diameter of the alginate fibre is chosen as a function of the flexibility and the softness to the touch which it is desired to obtain; it may preferably be comprised between one and two-tenths of a millimetre.

The strip of wadding is then applied on an adhesive tape of slightly elastic material, preferably provided with perforations for aeration purposes, by means of a nonreactive adhesive, for example with a base of latex. It is placed on this tape as and when the latter is unwound and coated with adhesive continuously or non-continuously.

In the usual manner, the tape thus obtained then receives laterally two sheets of plastic material or tarlatan which protect the therapeutic wadding and the adhesive portion, after which the whole is cut into sections of the desired length.

The dressing obtained is at the same time hemostatic, antiseptic right through, cicatrizing and resorbable, except only for the adhesive tape.

It will of course be understood that the invention is applicable to adhesive strips provided with any other therapeutic product in filaments, itself arranged in a carded, felted, woven or knitted strip.

What I claim is:

1. An adhesive bandage comprising a cover strip of adhesive tape and a pad of antiseptic, fibrous material affixed to said strip, said material being formed of a hemostatic, resorbable synthetic compound.

2. A bandage as set forth in claim 1 wherein the material is calcium alginate.

3. A bandage as set forth in claim 2 wherein the pad is a homogeneous layer of interlaced filaments.

4. A bandage according to claim 3 wherein the homogeneous layer is a non-woven fabric.

5. A bandage according to claim 4 wherein the pad is compressed, and the tape and pad are covered by a protective strip.
