    WOUND COVER AND WOUND CARE KIT
    The invention relates to a wound covering with a first boundary surface forming a first sheet-like element and a first boundary surface facing away from and approximately parallel to the second boundary surface forming and connected to the first sheet-like element second sheet-like element, and such a wound covering exhibiting wound care kit and a method for producing wound coverings of the invention.
    Such wound coverings are in various types of diseases or trauma, esp. In the area of the open abdomen needed when a temporary covering of the open wound or the open abdomen is necessary. This may be necessary, for example, if several interventions are required on a daily basis, on the one hand to allow rapid access to the internal organs and, on the other hand, to reduce a disadvantageous influence of exudate formation in the wound area. Temporary coverage can significantly reduce mortality in some indications.
    As suitable for the applications mentioned wound covers basically two main requirements are made from a medical point of view. On the one hand, a good exudate management in the wound area, in particular for use in the open abdomen, must be achieved. D. H. an extraction in the entire wound area or in the entire abdomen. In addition, a reduction in friction between organs and peritoneum and wound cover should be achieved, while at the same time the open wound is well shielded from the environment. In addition, it must be ensured that the wound cover does not contaminate the open wound or the open abdominal area.
    EP 0 261 167 B1 describes a liquid-permeable wound covering intended for direct contact with the wound base, which has a hydrophobic layer in order to prevent the adhesion of the wound cover to the wound area and contamination of the wound possibly caused thereby. With the wound covering described in this document, however, satisfactory exudate management in the wound area can not be obtained.
    In order to improve the management of exudate in the wound area, a wound covering is proposed in US Pat. No. 7,381,859 B2, in which a foam-like layer is accommodated between two liquid-permeable, sheet-like, sheet-like elements which may be in the form of plastic films, in which exudates are absorbed can. In the case of the wound covering known from this document, however, it has proved to be problematic that satisfactory marginal exudate extraction can not take place in the margins of the wound covering, so that complications in wound care occur in these marginal areas.
    In WO 2007/118652 A1, a wound spacer grid is described, are applied to the absorbent secondary dressings adhesive and which is equipped to form a first smooth surface and a second surface with a rough handle with a variety of three-dimensional perforations. When using this known wound cover the downstream absorption body are interchangeable, so as to ensure a satisfactory wound care over a longer period. However, even with the use of the wound covering systems described in the cited document, it has proven to be problematic that satisfactory exudate management over the entire wound area, in particular in the abdominal area, can not be achieved.
    In view of the problems in the prior art described above, the object of the invention is to provide a wound covering, with which even without contamination of the wound a good exudate management over the entire wound area is possible.
    According to the invention this object is achieved by a development of the known Wundab-covers, which is characterized essentially in that between one of the first boundary surface facing away from the first inner boundary surface of the first web-shaped element and a second boundary surface facing away second inner boundary surface of the second web-shaped Element is formed at least one drainage space, the depth of which in a direction perpendicular to the boundary surfaces extending depth direction capillary action on recorded in the drainage space body fluids, esp. Exudates guaranteed.
    In the wound covering according to the invention, a capillary action between the individual sheet-like elements is achieved by the formation of the drainage space, with the one hand, a drainage of body fluids, esp. Exudates prevented from the drainage and on the other hand a distribution of body fluids over the entire drainage possible without the need for additional measures, such as the provision of additional absorbent bodies. In this way, a good exudate management over the entire wound area is made possible because no exudate management adversely affecting border areas without capillary function are required. The wound covering according to the invention can be easily cut to any size or structure of wounds, in particular in the abdomen, and ensures the desired drainage function over the entire wound covering area. In this case, the wound cover can also be designed with a smooth surface, which prevents adhesion of tissues and cell wound or in the surrounding organs. The entry of body fluids into the drainage space can already be ensured when using wound coverings according to the invention in that the sheet-like elements themselves are formed from a liquid-permeable material.
    In the context of the invention, however, it has proved to be particularly advantageous if at least one of the web-like elements has a passage permitting the passage of body fluids into the drainage space. In this case, the stability of the overall structure of wound coverings according to the invention can be improved if at least one opening is formed by a channel extending from a strip-shaped element in the direction of the opposite inner boundary surface of the other strip-like element and opening into the drainage channel, the channel wall preferably being integral with the channel executed web-shaped element, esp. By perforation of the sheet-like element, is formed.
    In the last-described embodiment of the invention, the exudate management can be improved particularly effectively when the cross-sectional area of the channel in a direction perpendicular to the depth direction extending plane starting from the web-shaped element in the direction of the opposite inner boundary surface, esp. To obtain a the entry of body fluids in the drainage chamber favoring capillary action, reduced. In this way, on the one hand, the removal of exudate from the wound area is supported and, on the other hand, a backflow from the drainage space into the wound space is prevented.
    In wound coverings according to the invention the desired removal of the exudate can be achieved while ensuring a satisfactory overall stability of the wound cover, if at least one web-shaped element arranged a plurality of preferably grid-shaped, esp. In a rectangular grid arranged openings, wherein the distance between adjacent openings or grid points 15 mm or less, preferably 5 mm or less, esp. 3 mm or less.
    With regard to the desired overall stability of wound coverings according to the invention, it has further proven particularly expedient if the openings of the openings arranged in one of the web-shaped elements are arranged in a projection along the depth direction between the openings of the openings arranged in the other web-shaped element ,
    This arrangement of the openings in wound coverings according to the invention can be used with particular advantage in openings formed by channels, when the wound cover is used in conjunction with a negative pressure source used to aspirate the exudate from the wound area, esp. Abdominal space, so as to collapse to prevent the entire structure from applying negative pressure. In this connection, it has proved to be particularly favorable if at least one channel forming an opening in a sheet-like element extends in the depth direction over 50% or more of the total depth of the drainage space.
    To ensure the desired permeability of the sheet-like elements, it has proven to be expedient if the drainage space facing mouth surface of the individual openings in a direction perpendicular to the depth direction level 0.1 mm2 or more, esp. 0.5 mm2 or more, more preferably 1 mm 2 or more. The desired capillary action can be achieved while avoiding backflow of liquid from the drainage space into the wound space when the mouth area of the openings is 5 mm 2 or less, especially 4 mm 2 or less, particularly preferably 3 mm 2 or less.
    As already explained above, the channels forming the openings in the web-like elements can be formed by perforations in the web-shaped elements. In this context, it has proven to be favorable to obtain a smooth surface, with the adhesion of tissue or cells to the wound base or in the surrounding organs can be effectively suppressed, if the channel wall in a parallel to the depth direction extending cutting plane at least is executed in sections arcuate and steadily merges into the boundary surface of the sheet-like element. The connection of the web-like elements can be carried out with punctiform and preferably formed in a grid arrangement mounting areas while ensuring the drainage effect-producing drainage space. The attachment can be done by welding, gluing or other solid types of connection. However, the compound should not hinder the removal of exudates but support them. In this context, it has proved to be advantageous if the individual fastening regions have a surface of 5 mm 2 or less, in particular 3 mm 2 or less, particularly preferably 2 mm 2 or less, in a sectional plane extending perpendicular to the depth direction, the distance between individual attachment areas or individual grid points of the fastening areas executed in a grid arrangement is 2 mm or more, in particular 3 mm or more, particularly preferably 5 mm or more.
    Regardless of whether the attachment is carried out by welding, gluing or other connec tion types, the inner boundary surfaces of the web-like elements interconnecting material bridge may be formed in the attachment areas. To obtain the desired capillary action in the drainage space, the distance between the inner boundary surfaces of the sheet-like elements in wound coverings according to the invention is 5 mm or less, preferably 4 mm or less, particularly preferably 2 mm or less. In this case, the distribution of the exudates over the total area of the wound covering can be ensured by utilizing the capillary action in the drainage space if the distance between the inner boundary surfaces of the sheet-like elements is 0.05 mm or more, in particular 0.1 mm or more, particularly preferably 0, 3 mm or more.
    In wound coverings according to the invention at least one sheet-like element may have a preferably perforated plastic film, esp. Whole be formed in the form of a perforated plastic film.
    The wound covering according to the invention can be used to particular advantage in combination with the negative pressure therapy for wound care. In this case, the wound covering according to the invention is used as a wound dressing or as a direct interface between the wound base (tissue, cells) and the wound filler or the area of exudate removal. With particular advantage, the wound covering according to the invention is suitable for use in wounds in the open abdomen. In this case, the wound covering according to the invention is placed over the organs (viscera) in the entire abdominal cavity, the wound covering providing a drainage function and a very smooth surface in order to prevent adhesion or friction of tissue and foil. The wound covering according to the invention can be anatomically preformed, but also designed to be cut to size for special circumstances. When used in combination with the negative pressure therapy, a filling medium such as gauze or foam is filled up on the wound covering according to the invention until the area up to the skin boundary is covered. In this wound filler, a possibly tubular wound drainage can be inserted. The tube used for the discharge of the exudates or for wound drainage is led out of the abdominal cavity and connected to a vacuum source, which can be ensured by a pump or in the hospital by a central home care. Finally, the wound is occlusively sealed with an adhesive film. With the vacuum source, the exudate can then be removed from the entire abdominal cavity by means of the wound covering according to the invention, whereby a good exudate management is achieved. The film for the occlusive covering of the wound is responsible for the shielding of the internal organs from the outside world and regulates humidity and temperature. Furthermore, it is a barrier comparable to the skin against bacteria, viruses and germs.
    As the above explanation shows, a wound care kit according to the invention has a wound cover according to the invention, an absorbent body arranged thereon, such as a foam body or a gauze body, an occlusive film and possibly an optionally tubular discharge element connected to a vacuum source can be.
    A method for producing wound coverings according to the invention is essentially characterized in that a sheet-like material, for example. Using a punching roller, perforated to form funnel-shaped openings, two perforated sections of the sheet material superimposed with facing funnel openings and then, for example. By a spot welding process are connected. In this method, the desired distance between the inner boundary surfaces can be ensured by the depth of the funnel-shaped openings. However, the perforation process can take place only with limited accuracy, so that even if some funnel openings bear against the opposite inner boundary surface of the opposite web-shaped element, other funnel openings still open freely into the drainage space.
    With a view to avoiding the adhesion tendency of wound coverings according to the invention, at least one material web may have a hydrophilic or hydrophobic finish. Furthermore, it is also intended for the application of swellable materials.
    Between the individual material webs, an absorption medium, such as foam, gauze or a very open-pored material, provided, esp. Shattered, be within the drainage space. The use of superabsorbers or other storage materials between the webs is provided within the scope of the invention.
    Below, the invention with reference to the drawings, to which reference is expressly made with respect to all essential to the invention and in the description unspecified details explained. 1 shows a schematic representation of a wound covering according to the invention, and [0026] FIG. 2 shows an application example of a wound care kit according to the invention.
    The wound covering shown in Fig. 1 comprises a first, an outer boundary surface 12 exhibiting, web-shaped element 10 and a second, an outer boundary surface 22 exhibiting, web-shaped element 20. Between a second web-shaped element 20 facing inner boundary surface 14 of the first web-shaped element 10 and the first web-shaped element 10 facing inner boundary surface 24 of the second web-shaped element 20, a drainage chamber 40 is formed.
    The depth of the drainage chamber 40 in a direction perpendicular to the major surfaces of the sheet-like elements 10 and 20 extending direction is in the embodiment of the invention shown in the drawing between 0.1 and 4 mm.
    The first web-shaped element 10 has a plurality of grid-shaped, channel-shaped perforations 16. The channel walls of the channels 16 are arc-shaped in a sectional plane running parallel to the depth direction and smoothly merge into the outer boundary surface 12 of the first web-shaped element 10. Likewise, the second web-shaped element 20 has a number of grid-like, also channel-shaped perforations 26. The channels 16 and 26 each extend over more than half of the total depth T of the drainage chamber 40. The channels 12 and 16 are arranged such that a projection of the channel mouths of the channels 16 in the depth direction between the channel mouths of the channels 26 comes to rest ,
    In the mouth region, in the explained with reference to the drawing embodiment of the invention tapered channels 16 and 26 have a diameter of 0.2 to 1 mm. The web-shaped elements 10 and 20 are interconnected via grid-shaped material bridges 30. By the material bridges 30, the distance between the inner boundary surfaces 14 and 24 is set. The connection portions 30 can be realized by welding, gluing or other fixed connection types. The sheet-like elements 10 and 20 can be realized in the form of plastic films. Synthetic plastics, such as PE, PP, PET, polyurethane (PUR), Teflon (PTFE), as well as films based on biological plastics or renewable plastics, such as polyhydroxybutyrate (PHB), polylactate (PLA), can be used in this context. Polylactic acid, cellulose-based raw materials (CMC), etc. are used. The structure of the perforated material webs can be produced by means of a non-woven production process. Synthetic as well as natural (eg silk, cotton) fibers, as well as inorganic fibers (glass ceramic ...) or metal (silver fibers) can be used for the production of nonwovens or even fabrics. In the context of the invention, it is further contemplated that the webs 10, 20 and the drainage chamber 40 are equipped with an antibacterial or bacteriostatic layer. The antibacterial or bacteriostatic effect can be realized, for example, by PHMB, silver, chlorhexidine, etc.
    According to the illustrated with reference to Figure 2 application example, the wound cover 2 is placed on the wound base, the wound then od with a filler material, such as a foam, gauze. Like., Padded and covered with an occlusive film 50. The occlusive foil 50 is penetrated by an exudate line 6, which can be connected to a vacuum source for sucking the exudate out of the wound space.
    When using wound coverings according to the invention, the following advantages result, as explained above: The pores with their inwardly rising structure support the removal of exudate and prevent the backflow of the exudate into the wound space (capillary action).
    The open drainage chambers give the drainage layer 40 a capillary action and thus do not allow drainage from the wound cover.
    By the smooth transition between the channels 16 and 26 and the outer
    Containing surfaces 12 and 24 of the web-like elements smooth surface prevents adhesion of tissue or cells on the wound base or in the surrounding organs.
    The combination of pore size and smoothness of the film prevents tissue ingrowth or adhesion.
    The drainage chamber 40 always offers an open space for the removal of Exsu dat.
    The wound cover can be cut to any size or structure in the wound or abdominal area without impairing the drainage function.
    Finally, it should be noted that the distance between the center axes of the channels 16 and 26, as indicated in Figure 1 at a and b, explained with reference to the drawing embodiment of the invention is at least 0.1 mm and a maximum of 4 mm.
    The invention is not limited to the embodiment explained with reference to the drawing. Rather, wound covers with differently shaped openings and / or a multi-layer structure for forming two, three or more superimposed drainage chambers are also conceivable. In this case, the boundary surfaces facing away from the inner boundary surfaces of the web-like elements form no outer boundary surfaces at least in the inner webs of material.
