Publ~e Avec rapport de recherche internationate 'iz' (54)Title: DRESSING MATERIAL HAVING A POLYMERIC FIBRE CORE (54) Titre: PRODUIT DE PANSEMENT A AME DE FIBRES EN POLYMERE (57) Abstract A dressing core in the form of a cylindrical tuft is surrounded by a sheath 3) for supporting its mechanical structure.
The sheath which may consist of threads is permeable to the biological fluids of wounds and biocompatible therewith.
The dressing is particularly suitable for deep wounds since it is readily removable therefrom, (57) Abrkg6 L'fime en forme de mache cylindrique, du pansement est entour~e d'une enveloppe 3) de maintien de la structure m6cs~nique de l'Ame. L'enveloppe qui peut 6tre constitute de fils est permeable au liquide biologique des plales ct biocoinpatible avec, des plaics.

F P C K) 1 DRESSING PRODUCT WITH A CORE OF POLYMER FIBRES The present invention relates to a dressing product or dressing for a wound with biological fluid, comprising, in a substantially cylindrical form, a core of fibres of a spinnable polymer.
Dressings of this type, generally in a pack form, are often used for weeping wounds, particularly deeps ones such as bleeding cavities like bedsores or other, post-operative wounds.
The polymer is often an alginate of a metal selected from the group of multivalent metals, with the exception of magnesium, and in particular alginate of calcium.
A wound causes a loss of substance or of biological fluid (blood or exudate), When applied in a wound the dressing begins to absorb the oozing or bleeding biological fluid, the water molecules of the liquid becoming interspersed between the macromolecules of the alginate. Once swelled up by absorption, the dressing undergoes jellification due to ionic exchange. In the case of calcium alginate fibres they lose Ca 2 to the biological fluid which gives up Na+ ions to them.
As the equilibrium between the calcium and the sodium takes place, the alginate fibres partially lose their crystalline structure. The jellification of the dressing causes the wound to dry and prevents the dressing adhering to the ,subjacent tissues. However, jellification also causes lP:\WI'D[OCSMAP\SI'ECl 51808fDIl- 8/9/97 -2splitting of more generally a change in the integrity of the mechancal structure of the core which may make it difficult to remove from the wound without causing pain.
It is the aim of the present invention to prepose a dressing product of the aforementioned type with the capacity for absorption, retention and jellification intact but which can be easily and painlessly removed from a wound.
In one broad form, the present invention provides a dressing product for a wound with biological fluid, comprising, in a substantially cylindrical form a core of fibres of a spinnable polymer formed of an alginate of a metal selected from the group of multivalent metals, with the exception of magnesium, characterised in that the core is surrounded by a holding sleeve of a structure permeable to biological fluid and biologically compatible with the wound.
15 Thus, while retaining the mechanical cohesion of the fibrillary core, the sleeve neither alters the action of the absorption, dilation or jellification intended to extract the biological fluid, nor the action of retaining proteins and other cellular and bacterial waste which otherwise would hinder the scarring process.
The sleeve can be fibrous, having one thread or several. A single thread can connect the fibres of the core by meshing, in particular by so-called chain stitches, by winding, in particular with contiguous turns, for example. In the case of several threads they can, for instance, be meshed, plaited, twisted or woven around the core.
The sleeve can be a porous sheath or openwork sheath.
l I 3 Biologically compatible covering materials include, for example, biologically compatible polymers such as polyesters, polyamides, viscose, and moreover, biologically absorbable polymers.
A polymer for the core can be a spinnable alginate of a metal selected from the group of multivalent metals, with the exception of magnesium.
In particular the alginate of calcium can be considered as a spinnable alginate.
The invention will be understood with the aid of the following description of several embodiments of the dressing product of the invention, with reference to the attached drawing in which: Fig 1 illustrates a perspective view of a pack with two twisted holding .threads; Fig 2 illustrates a profile view of a pack with a holding thread wound in contiguous turns; Fig 3 illustrates a profile view of a pack with a holding thread meshed by chain stitches; Fig 4 illustrates a profile view of a pack with an openwork holding sheath and Fig 5 illustrates a profile view of a pack with a porous holding sheath.
R4A4. The technique for producing a core, or pack, of polymer

W=47v' 4 fibres, in particular of alginate, and more particularly calcium alginate, for a wound with biological fluid is now well proven and therefore does not need to be explained here, no more than the textured or untextured structure of such a pack. It merely needs to be stated that a pack is of a substantially cylindrical and elongated form. In order to avoid it splitting or disintegrating, in short, losing its mechanical cohesion, it is held, in the embodiment shown in the drawings, by a sleeve which is permeable to biological fluid and is biologically compatible with the wound to be dressed.
In the embodiment of Figure 1, the pack 1 is held by two threads 2, 3 twisted around the pack in a relatively widely spaced manner.
In the embodiment of Figure 2, the pack 1 is held by a single thread 4 wound around it in almost contiaguous turns.
In the embodiment of Figure 3, the pack 1 is held by a single thread 5 meshed by regularly-spaced chain stitches 6.
In the embodiment of Figure 4, the pack 1 extends inside a sheath-sleeve 7 pierced by holes 8 for the passage (drainage) of the biological fluid.
In the embodiment of Figure 5, the pack 1 extends inside a sheath-sleeve 9 which has a porous wall for the passage of the biological fluid.
P ro3~' In all the embodiments described above, the biological fluid is still perfectly drained by the fibrillary pack. The threads or sheaths which surround it prevent it from splitting and from being in intimate contact with the wound.
The substances trapped by the fibrillary gel are therefore no longer in contact with the wound. The pack can then be easily and painlessly removed from the wound.
