Definitions

  • a surgical textile dressing consisting of one or more layers of non-woven fabric which is needled vertically to its plane so that Wicklike fiber bundles extend through the fabric, and wherein the entry side of the needles into the fabric which engages with the wound is provided with a thin coating of adhesive which connects the uppermost fibers but leaves intermediate spaces through which the moisture of the wound will be absorbed.
  • the present invention relates to a surgical dressing of a textile material which is made of a non-woven fabric or fleece material.
  • a good textile dressing The general requirements of a good textile dressing are that it be highly absorbent, have a sufficient capacity for absorbing secretions, and allow air to penetrate easily. Furthermore, it should rest on the wound without folds, be nonirritant, and not stick to or grow together with the wound.
  • Another known kind of surgical dressing comprises a fleece material in which the gaps between the fibers are reduced by compression and the contact surface of which is treated with aluminum by vapor-deposition in order to prevent the dressing from sticking to the wound.
  • a similar effect is supposed to be attained by another .kind of dressing which consists of a sheet of polypropylene into which numerous small holes are punched and upon the upper side of which a wide-mesh gauze is glued.
  • Both of these surgical dressings have very little, if any, absorptive properties and therefore require an additional layer of an absorbent material.
  • this object is attained by needling the non-woven fabric or fleece material and applying a thin coating of adhesive upon the uppermost fiber layer on the entry side of the needles which is ap- 3,4825% Patented Dec. 9, 1969 ICC plied upon the wound so as to connect the fibers of this layer to each other.
  • Another feature of the invention consists in providing a supporting fabric within the needled fleece, for example, in the form of absorbent gauze.
  • This supporting fabric with the needling of the non-woven fabric or fleece results in a relatively solid surgical dressing of stable dimensions.
  • the present invention further provides that the adhesive is preferably died to a heat-absorbing color.
  • the present invention is further directed to provide a method of producing this dressing.
  • This method consists of the steps of needling the nonwoven fabric or fleece and thereafter passing it through a pair of revolving coating rollers upon one of which a uniform layer of adhesive of a thickness of about 25 to 50 ,um. is applied by a doctor blade.
  • This adhesive is then transferred from this roller upon the needle-entry side of the fleece.
  • the coated fleece is then compressed, for example, between a pair of revolving rollers.
  • the method according to the invention may be carried out continuously and therefore permits a very economical production of the new surgical dressmg.
  • the invention further provides that, immediately after the needled fleece leaves the coating rollers, its coated side he treated with strong jets of compressed air.
  • FIG. 1 shows an enlarged cross sectional of a piece of the surgical dressing according to the invention
  • FIGURE 2 shows a top view of the piece of dressing according to FIG. 1.
  • the surgical dressing according to the invention consists essentially of a needled layer of non-woven fabric or fleece material 1, wherein the uppermost fibers 2 on the needle-entry side 3 are connected to each other by an adhesive coating 4.
  • the fleece itself consists of cotton and/ or rayon staple fibers as employed conventionally, for example, for producing absorbent cotton for medical purposes.
  • This fleece 1 is pierced in a needling machine approximately 150* times per cm. and its structure is thereby changed in the manner as illustrated in FIGURE 1. It then consists partly of fiber bundles 5 which extend substantially vertically to the longitudinal plane of the fleece 1 and partly of fibers 7 which extend substantially parallel to this longitudinal plane. At the points of entry of the needles of the needling machine, these needles form funnellike recesses 6.
  • the fleece 1 After the fleece 1 has left the needling machine, it is passed through a pair of revolving rollers, one of which carries a uniform layer of an inert, polymerous, Waterunsoluble elastic adhesive 4 of a thickness of about 0.05 mm. which is made on a basis of silicon rubber, cellulose acetate, polyisobutylene or polyamide.
  • This adhesive is transferred by the coated roller upon the fibers 2 of the uppermost layer of fibers of fleece 1 on the: entry side 3 of the needles.
  • the coating rollers should, however, compress the needled fleece 1 only very slightly so as to prevent the lower parts of the funnellike recesses 6 in the fiber bundles 5 from being clogged by adhesive.
  • the coating operation should therefore be carried out so that the adhesive 4 only penetrates into the fibers of the uppermost fiber layer at the entry side of the needles.
  • the surgical dressing which is thus basically completed is treated by means of strong jets of compressed air so that the small strips of adhesive which connect many of the individual fibers to each other will be torn apart and the adhesive will be deposited primarily on the points of contact and intersection between the uppermost fibers 2.
  • the dressing material is once more compressed between another pair of revolving rollers so that the coated uppermost fibers 2 will engage with and be glued to each other at additional points.
  • the coated side of the material which is to be applied upon the wound is provided with a very smooth contact surface which may therefore be very easily separated from the wound. Furthermore, the adhesive is then no longer capable of combining additional fibers, for example, in the funnellike recesses, so that the absorptive capacity of the needled fleece will not be dimnished.
  • the adhesive 4 of the surgical dressing according to the invention may, in addition, be provided with a heat-absorbing coloring matter so that the side of the dressing facing the wound will absorb the heat of the wound and dissipate it to the outer air. The heat which may be radiated from the outside upon the other side of the dressing will be reflected to the largest extent by the many white fibers. The dressing according to the invention will therefore reduce the temperature of the wound considerably.
  • the fleece 1 Before being treated by the needling machine, the fleece 1 may also be applied upon an additional supporting fabric, for example, absorbent gauze, and thereafter be needled.
  • additional supporting fabric for example, absorbent gauze
  • a surgical dressing of a textile material comprising a needled fiber fleece including an uppermost layer and a coating of adhesive connecting the fibers of the uppermost layer of said fleece to each other at the entry side of the needles into said fleece, adapted to be applied upon a wound,
  • said fleece being needled in a direction vertical to said plane and forming funnel-like recesses in said entry side
  • said fleece being composed of several layers of straightened fibers substantially parallel to and superimposed on each other, and
  • said fibers of each layer extending at substantially right angles to those of the adjacent layer.
  • the surgical dressing as set forth in claim 1, which includes a supporting fabric in said needles fleece.
  • a method of producing a surgical dressing of a textile material comprising the steps of needling a fiber fleece in a direction vertical to its plane,
