Definitions
- the invention relates to a wound dressing for wound treatment, in particular in a moist or moist wet environment, with a wound pad, wherein the wound pad manufacturer with a salt-containing aqueous solution, in particular
- Ringer solution applied and can be included in an outer packaging, wherein the wound pad
- Such a wound dressing for wound treatment in a moist or wet-moist environment is known from WO 2011/141454 A1 or EP 0 594 034 B1 of the Applicant.
- This is a pillow-like or compress-like wound dressing which can be applied to a wound or can also be used to stamp out deep wounds.
- the Wound pad is designed here as a suction / rinsing body and is supplied by the manufacturer with a salt-containing aqueous solution, which swell contained in the absorbent / rinsing superabsorbent material and into a
- Decubital ulceration or ulcus cruris is preferred.
- the present invention is based on the object, the wound dressing from the outside against a wound surrounding the wound
- Circumferentially encloses the circumferential direction, and that the edge-side adhesive coating having areas of the layer projecting beyond the wound pad manufacturer for delivery to the consumer by folding at least four fold lines on the side facing away from the wound
- Wound pads are folded so that the fold lines enclose the wound pad in the circumferential direction, and that the folded areas are covered by the manufacturer side of at least one removable protective layer which is parallel to the plane.
- the wound pad is thus surrounded in the circumferential direction by an adhesive edge area.
- Edge region is then folded over the at least four fold lines on the wound or body side facing away from the wound dressing.
- the removable protective layer is then provided which overhangs and thus covers the folded, adhesive-coated areas.
- the wound pad is not folded but extends in a plane.
- the removable protective layer is also in this plane or extending parallel thereto.
- the wound dressing is fixed to the patient by means of the adhesive regions folded on the side facing the side of the wound, which are produced by the manufacturer and still when removing the wound dressing from an outer packaging.
- the wound dressing is so on the patient
- the user or a caregiver can replace the at least one protective layer. Because the protective layer releasably adheres to adhesive coated folded portions of said layer radially overlying the wound pad, release of the protective layer may be used simultaneously to fold back at least one of the folded portions toward the user's skin surface. In this way, the wound dressing is then once attached to the user liable, so they do not
- Wound dressing is fixed on the patient. It will
- the wound dressing is approximately rectangular or square, and that four, in particular rounded, corner regions project beyond the wound pad and at the marginal edge
- Adhesive coating layer are provided and that the four corner regions are folded over each fold line on the sore side facing away from the wound pad and that four areas of the layer between the corner regions are in turn folded over a respective fold line on the side facing away from the wound pad, so that they previously folded corner areas at least partially
- the wound dressing is again positioned on the patient, covering the wound. Then the
- a first folded portion is folded against the skin surface of the user, as described above. After gently pressing this adhesive area against the skin surface, the wound dressing is positioned and the remaining areas can be folded back accordingly. The four remain in the course of production as the first on the
- Corner areas are finally after radially outward in the direction of the skin surface of the
- Adhesive coating layer are each covered with a peelable and corresponding to the corner regions extending peel sheet, so that the areas folded on it do not adhere.
- the fact that the corner areas are covered by the manufacturer with a peelable peel film, can be prevented according to the invention that the subsequent folded on the side facing away from the wound on the previously folded corner areas too strong and complicate a detachment in the course of applying the wound dressing on the patient.
- the at least one detachable protective layer can also have two or more separate protective layer sections which can overlap one another and, in particular, can be detached independently of one another such that, upon detachment of the protective layer sections, two opposite folded-over regions are folded back around their fold line and the two other folded areas essentially
- the fold lines are preferably parallel to each other, and that the folded areas are covered by a removable first protective layer, and that two second opposite each other with respect to the wound pad
- Areas of the layer projecting beyond the wound pad and having the edge-side adhesive coating are each folded around the wound pad on the side of the wound pad which is tangent to the wound pad, the fold lines preferably being parallel to one another, and the folded-over second areas being overlapped by a detachable second protective layer , In this embodiment, therefore, is a separate
- the wound dressing is again positioned and after detachment of the uppermost second
- Protective layer can fold back the second opposite edge areas, ie in the direction of the
- the two first and the two second fold lines are substantially orthogonal to each other.
- the wound dressing is used in a moist or wet-moist environment and this is already supplied by the manufacturer with a salt-containing aqueous solution, it is advantageous if the marginal
- Adhesive coating manufacturer is protected from direct contact with the aqueous solution. This can be achieved, for example, by coating those areas of the layer projecting beyond the wound padding on the edge side of the adhesive layer with a water-impermeable layer on the manufacturer side. This layer may also be the one mentioned above
- detachable protective layer act.
- a fluid access could still be in the plane of the
- edge-side adhesive coating on the projecting beyond the wound pad layer of an inner and an outer circumferentially continuous and self-contained, in particular made of silicone bead is bounded radially inward and radially outward with the bead slightly raised from the layer on its sore side. This bead can then act as a radial seal between the the edge-side adhesive coating bearing layer and the protective layer act.
- the layer having the edge-side adhesive coating projecting beyond the wound pad on the
- a receiving space for the adhesive is created, which can be relatively easily and effectively sealed by a liquid-tight protective layer.
- the wound pad is formed by a particular fiber fleece-based suction / rinsing body.
- a foam-based suction / rinsing body would be conceivable.
- the wound pad comprises a covering forming the outer visible sides of the wound dressing. It can then be formed with further additives, such as superabsorbent particulate materials.
- the wound pad can be held together in a compact manner as a flat layer.
- the wrapping on the wound-facing side of the wound dressing comprises a layer of a textile sheet material, in particular of a knitted fabric, knitted fabric or fabric. This will be a
- Fluid exchange between the wound pad and the Wound room allows, as the aforementioned textile
- Nonwoven layer comprises, which forms the wound-facing outer visible side of the wound dressing, and that on the
- the nonwoven layer, the Kunststofffmm slaughter, the wound pad and the layer of textile sheet material are not areally connected to each other, but with their flat sides loosely and slidably against each other, wherein the nonwoven layer, the Kunststofffmm slaughter, the wound pad and the layer of textile sheet material are not areally connected to each other, but with their flat sides loosely and slidably against each other, wherein the nonwoven layer, the Kunststofffmm slaughter, the wound pad and the layer of textile sheet material are not areally connected to each other, but with their flat sides loosely and slidably against each other, wherein the nonwoven layer, the
- Kunststofffilm Mrs the wound pad and the layer of textile sheet material along only one peripheral edge of the wound pad by a joint connection, in particular a Ultraschall hydrogeraum, are interconnected.
- wound-facing outer visible side of the wound dressing does not have the same effect as in the case of the previously known product of an artificial textile film layer, but of a
- Nonwoven layer is formed, the tactile and haptic graspability of the wound dressing, also by means of instruments, improved because the nonwoven layer is less slippery than a Kunststofffilm für, but also in the wet state can be described as handy. Furthermore, the appearance and feel, especially in contact with the gloves of the nursing staff and with the body surface of the patient, is improved. Further it proves to be advantageous that the flexibility and the drapability of the wound dressing according to the invention is improved. It was surprisingly found that the Kunststofffmm Mrs not arranged outside but on the wound facing side of the nonwoven layer does not hinder the flexibility and drapability of the wound dressing, which is also attributed to the fact that the layers are not connected to each other but only along the edge of the wound pad, so that they according to the invention with their flat sides only loose and
- Adhesive coating layer forms. According to this inventive concept, therefore, the envelope of the wound pad, in particular of the suction / rinsing body, or a layer of this envelope at the same time for the formation of the over
- Tissue pad protruding layer used, which receives the edge-side adhesive coating.

- the basis weight of the fiber portion of the suction / Spül stresses advantageously 20 to 500 g / m 2, preferably 30-300 g / m 2, more preferably 30-200 g / m 2, especially 30-150 g / m 2.
- Fiber content of the suction / Spül stresses 20-500 kg / m 3 preferably 30-300 kg / m 3 , more preferably 50-200 kg / m 3 .
- the layer of textile sheet material is formed from a thermoplastic material, in particular from polyolefin, in particular from polypropylene. Furthermore, it proves to be advantageous if an atraumatic-acting coating is provided partially and structured on the wound-facing side of the wound pad or the absorbent / rinsing body.
- Degree of coverage of the partially and structured applied atraumatic coating is 20-70%, in particular 25-50%, in particular 30-40%. It proves to be more advantageous if the partially and structured applied atraumatic coating.

- the width of the joint transverse to its longitudinal extent is preferably very small, so that it is barely perceptible on the finished product.
- the wound-facing coating layer 8 and the wound-facing coating layers 10a, b are separated from one another stretched so that the impression of a very flat marginal rounded wound pad arises.
- wound-facing envelope layer 8 a partially and
- Coating 22 is provided.
- This coating 22 is preferably a silicone coating, wherein the
- Coating in the case exemplified is formed by a plurality of relatively thin strips 24 or lines or inseiform areas which are separated from each other by non-coated areas. In these uncoated areas is the sore
- Envelope layer material remains open three-dimensionally and provides or retains less resistance to fluid passage in both directions over the useful life of the wound dressing.
- the nonwoven base of the absorbent / rinsing body 4 consists of 33 g / m 2 cellulose fibers (pulp), 11 g / m 2 polypropylene / polyethylene fibers as binder fibers. 70 g / m 2 of the abovementioned superabsorbent polymer materials (SAP) are mixed homogeneously with this fiber mixture.
- the mixture thus obtained (nonwoven base + SAP), which forms the suction / rinsing body 4 can also from a cellulosic tissue layer, in particular a basis weight of exemplarily 17 g / m 2 on each side, be surrounded (not shown in the figure); however, this is not mandatory.
- the wound dressing can be designed, for example, round or rectangular, with an exemplary dimension of the wound pad 2 or of the suction / rinsing body 4 of 5-10 cm.
- edge adhesive coating 32 is provided, which projects beyond the wound pad 2 radially outwardly
- the one projecting radially beyond the wound pad 2 is outwardly projecting
- all enveloping layers 8, 10a, 10b or only individual layers can be used to form the layer 34 projecting beyond the wound pad 2.
- Wound-facing side 14 of the wound dressing 1 folded over and there overlaid with a removable protective layer.
- FIG. 2 illustrates the partial and structured application of the atraumatic coating 22, which is applied here in the form of strips 24.
- Figure 3a shows the wound dressing 1 with a view of the
- edge-side adhesive coating 32 of the layer 34 completely surrounds the wound pad 2 in the circumferential direction 30. It can be seen further four corner areas 38 with a respectively indicated fold line 40. These corner portions 38 are exemplary but not necessarily covered with a peelable peel film 42. The corner regions 38 are then folded over by the manufacturer on the side facing away from the wound (FIG. 3C).
- FIG. 3d shows the view of the wound dressing folded in this way with a view of the side facing away from the sore. It can be seen that the adhesive coating of the corner regions 38 also shows
- Adhesive coating 32 turned upwards (Fig 3e). Then, a removable protective layer 48 is applied, which is formed by way of example of two separate detachable sections.
- the wound dressing with its wound-facing side 20 is placed on the wound, whereby the wound pad 20 should completely cover the wound.
- the portions of the protective layer 48 are detached with two hands simultaneously or sequentially in the direction of the arrows 50, whereby their associated transversely to the arrows 50 extended folded portions 44 are folded back toward the wound facing side 8 and then with their adhesive coating 32 on Patients can adhere.
- the two further regions 44 are folded back outward about their respective fold line and also attached to the patient.
- the respective peel sheets 42 are removed from the folded-over corner regions 38 and then these corner regions 38 are also folded back outwards, so that the wound dressing then with its in the circumferential direction 30 continuously passing edge-side adhesive coating 32 on
- FIGS. 4a-c show a further embodiment of the wound dressing according to the invention, in which corner regions are not folded over separately.
- Adhesive coating 32 and over the wound pad 2 protruding layer 34 comprises two first opposing portions 60. These first portions 60 are about a respective fold line 62 on the
- Adhesive coating 32 of the folded-over first regions 60, a first protective layer 64 is applied (FIG. 4b).
- Areas 66 of the layer 34 are folded over respective fold lines 68 on the side facing away from the sore 14, and a second removable protective layer 70 is applied, which corresponds to the planar extent of the configuration thus obtained and the adhesive coating 32 of the second folded regions 66 overlaps ( Figure 4c).
- the wound dressing with its wound pad 2 is positioned on the patient, covering the wound. Then the second
- Protective layer 70 detached and with the fingers of the same or the other hand, the second portions 66 in Direction of the patient folded so that they can adhere to the patient with their adhesive coating 32. Thereafter, the then-apparent first protective layer 64 is peeled off, and the first regions 60 are folded in the direction of the skin surface of the patient, so that the wound dressing with a continuous in the circumferential direction of the wound pad 2 adhesive coating 32 at the skin surface surrounding the wound of the patient.
- FIG. 5 shows schematic sectional views of a
- Beads 80 thus form a receiving space for the
- Adhesive coating 32 By means of a removable protective layer 82 that covers this receiving space, the adhesive can be protected from the effects of moisture. If this wound dressing is folded by the manufacturer according to the invention, it may prove advantageous that the
- wound-facing side of the wound dressing is applied and in particular by the protective layers 48, 64, 70 is formed.
- the layer 34 projecting beyond the wound pad 2 has several deep-drawn layers Grooves 84 which receive the adhesive coating 32.
- the adhesive can be protected from moisture by a removable protective layer 82.
