According to a third aspect of the present invention, provide a kind of and be used in Wound healing and bone regeneration process location and the combination that keeps the dressing that the sleeve component of conduit and/or pipe uses together, dressing comprises the laying that has adhesive coating on it, in order to dressing is bonded on the patient; Laying wherein has otch in order to receive sleeve component, and sleeve component wherein has at least one aperture in order to receive conduit.

In the combination according to a third aspect of the present invention, sleeve component preferably also comprises the flange portion that extends around at least a portion of the main part of sleeve pipe, in order to sleeve component is attached on the laying of described application of adhesive.

Laying can be thin flexible thin-film material, and comprises any suitable material known to ordinary skill in the art, and can comprise one of material of describing among the EP-A-0751757, and document integral body is hereby expressly incorporated by reference.For example, laying can comprise for example polyester or the polyurethane of polyether-type chaste tree ammonia ester and the material that can buy, for example OPSITE (trade mark) or TEGAERM (trade mark).What wish is that the gasket material of as known in the art such initial supply has the protective layer on the adhesive coated faces of being bonded in and preferably is positioned at supporting (being sometimes referred to as " carrier ") layer on the reverse side of adhesive coated faces.Protective layer can also be any material on the reverse side known to a person of ordinary skill in the art, and the releasable paper of silicone-coating is an example.Supporting course can also be any suitable material well known in the art, and its suitable example can comprise paper, paillon foil or thin polymer film.Preferably, supporting course bonds on the laying more securely than protective layer, so that when protective layer was stripped from, supporting course kept to prevent any undesirable gauffer of laying, helps it to process, and keeps the overall two-dimensional shape of laying.In case dressing bonds on the patient, supporting course then is stripped from.

Suitable binding agent can be the known contact adhesive of dressing field those of ordinary skill.

In the first embodiment according to dressing of the present invention, the otch in the laying can be the form that cuts at an edge of laying, effectively so that the shape of laying becomes " Horse hoof " form.Preferably the direction of the conduit in the sleeve component can be aimed at the intramarginal otch of dressing also through on it.

In according to the second embodiment of the present invention, this otch can be the aperture in the laying, so that laying becomes annular, and Q-RING for example.

The orifice shapes of laying is preferred, this is because sleeve component is whole around its periphery supporting, and the adhesive phase on the laying can be used to around the whole periphery of laying and sleeve component dressing be bonded on the patient, therefore the sealing of the patient skin of enhancing and dressing.

But shape of a hoof laying is acceptable, and wherein sleeve component seals with ambient air on wound side.The advantage of the shape of this dressing is that patient skin can breathe or perspiration is discharged into periphery via open edge below sleeve component.Sleeve component is preferably formed by the flexible polymer plastic material.In certain embodiments, shell material also can be made by Stretch material.Usually, the sleeve component material can have the Shore hardness of 55A-70A scope, and conforms to patient's profile easily, but this hardness implication without limits not, and the hardness beyond this scope is applicable to sleeve component according to the present invention.The suitable material that is used for sleeve component for example comprises TPE, polyurethane, ethylene vinyl acetate copolymer, silicone, polrvinyl chloride.In addition, sleeve component usually covers and remains on the patient skin in addition by the overlapping adhesive strings material film that covers whole wound location.As selection, as mentioned above, sleeve component can arrange adhesive coating on the surface of contact patient skin, and the surface of application of adhesive arranges protective layer and laying at first.Therefore, dressing and sleeve component are sealed on the patient fully.

In dressing near wound when being attached on the patient skin, hope be that sleeve pipe has had the required one or more conduits that are mounted, to prevent that the patient is caused any unwanted additional misery or pain.Conduit is attached on the catheter component supplier and/or manufacturer that can be by sleeve pipe or can introduces the aperture by nursing staff or healthcare givers.

The dressing laying have an edge cut form the time, protective layer and supporting course can be easily removed around described one or more conduits.But in the situation of the substrate layer with closed aperture, supporting course need to cut in some mode, in order to remove conduit when removing.In this case, supporting course can be for example by a pair of shears tear fracture or cut, but preferably three layers are cut in a side in the dressing manufacture process and are worn.

Sleeve component arranges at least one aperture of running through, in order to receive one or more conduits.In relating to the treatment of wounds of TNP treatment and in the flushing of describing in the described international patent application in our the common examination and/or the cleaning process, need a plurality of conduits, the aperture that can separate for each conduit with a plurality of chambers or pipe setting.As selection, can adopt the single conduit with a plurality of chambers that run through, and the aperture of passing sleeve component can be shaped suitably, for example form the cross section in elongated " flat " hole.

At least one aperture of preferably passing sleeve component arranges sealing device so that the conduit of hermetically passing does not make its in use leak fluid.This sealing device preferably includes flexible convex lip seal, round section joint ring sealing or the sleeve shaped sealing that cooperates with the outer surface of conduit.This protruding lip seal is set so that does not leak at the interface of conduit and sleeve aperture, and the power that has also reduced to need to regulate the position of conduit in sleeve component on being bonded in the patient time, its advantage is obvious.

In certain embodiments, sleeve component and sealing are formed by the material of relative stiffness.Make common the same the work well of flexible material of adopting with conduit of sealing of rigid form, conduit is made by relatively soft and conformable material usually.

Dressing laying member and sleeve component are supplied as two integral body of separating of dressing of the present invention at first, have different protective layers and supporting course, and two integral body then fit together on being applied to the patient time.But preferably sleeve component is attached on the laying under manufacturing step in manufacture process.

In the situation that sleeve component is supplied in the mode that is bonded on the laying on every side, protective layer can be arranged to cover the single parts of the binding agent coating surface of laying and sleeve component, and no matter latter's application of adhesive whether.

Preferably dressing can be supplied under having laying and the sleeve component that combines and the situation that also has the suitable conduit at least one aperture that has been installed in sleeve component in addition.

At laying and sleeve component as two separate integers for seasonable, the protective layer on the laying can be arranged in a plurality of parts, cut and wear and/or provide in manufacture process.For example, can be the separately form of the narrow border of dismounting of width that corresponds essentially to the flange portion of sleeve component near the protective layer of cut out portion, this boundary member at first is removed, so that sleeve component is bonded on the laying at first.

In known manner, protective layer can be formed by a plurality of parts, in order to improve the convenience of processing and the manipulation of dressing when being applied to it on patient.In this regard; protective layer can be configured to make its major part to be removed at first; so that dressing makes things convenient for and is positioned on the patient exactly; and for the other parts that are bonded in the application of adhesive laying on the patient; less, the folded part that stay protective layer are removed at last, and do not have adhesive phase for example to be applied the medical worker's of dressing the probability of finger pollution.After being bonded in dressing on the patient, supporting course can be peeled off at last, stays laying, sleeve component, and wherein conduit is in situ gone up.For example the flexible strip covering of the known adhesive material of OPSITE (trade mark) can then be placed in position at last, roughly covers by bonding laying, sleeve component, stays conduit in the wound location environment and the other parts of wound area.

In the 3rd embodiment of dressing of the present invention, laying can comprise two separate sections, and wherein relatively surperficial the and sleeve component of application of adhesive is clipped between the surface of two application of adhesive.In this embodiment, it is two that the first of laying is effectively folded, and wherein protective layer is positioned on outer adhesive coated faces.The protective layer that comes from one of two surfaces of first at first is removed, and the surface of the application of adhesive that is exposed is bonded on the patient skin in position with respect to wound.Second protective layer then removed from adhesive coated faces facing up, and sleeve component then is bonded on the second surface of first.The second portion of gasket material can then be placed to the overlapping casing tube member, and it is clipped between the first and second layings part.Preferably the length of two laying parts is in 1 times to 5 times scope of the transverse width of sleeve component, so that the multiple-length of crossing of each laying part is enough to mutually form strong bonded at the either side of sleeve pipe.Also be foldable to two if wish second portion, so that sleeve component is clipped between the adhesive coated faces of the first and second layings parts, and other also application of adhesive of surface facing up of second portion.Therefore; when sleeve component is in place on patient skin; the second laying part can stay in adhesive coated faces facing up a slice protective material; this protective material can be peeled off before whole dressing and other wound area are covered by the flexible strip covering at last, as the embodiment of front.

But, be the first and second liner synusia in 1 times to the 5 times scope although described dressing has length, they in fact can be longer, and for example folding one or more pieces are placed at diameter or the width of large wound.

But the second portion of laying does not need to be folded into two in the 3rd embodiment.The second portion of laying can be the single layer with surface that does not have application of adhesive of adhesive coated faces by protective layer protection and the reverse side by the supporting course protection, as the embodiment of front.In this case, sleeve component will be clipped between the adhesive coated faces of the first and second layings, and the adhesive coated faces that do not have facing up that stays the second laying part is protected by supporting course.Supporting course can then be peeled off before the other parts of dressing and wound location cover by thin-film material flexible, application of adhesive, the thin-film material of application of adhesive is bonded on the facing up surface of the second laying part, so that the Sealed casing pipe member, so that surrounding air can not enter.

Can be known as OPSITE (trade mark) or TEGADERM (trade mark) according to the present invention for the suitable material of the laying of dressing and the example of overlapping flexible drape film.

In the third embodiment of the present invention; the first and second layings partly can be used as the flat sheet material supply of the suitable material that comprises laying, protective layer and supporting course or provide; by sleeve component being clipped in the step between the first and second layings; then by peeling off protective layer, fold as required and being bonded on the patient, the healthcare givers is prepared it.But; the dressing of the 3rd embodiment can with two that are clipped in gasket material the first and second parts of separating between the form of sleeve component assembling provide, wherein have suitable protective layer or protective layer and supporting course towards outer surface and keep original position in order to before being bonded on the patient, remove.

In the 3rd embodiment, second, the upper liner layer segment can be actually the overlapping band that covers whole wound location.

In the 3rd embodiment according to dressing of the present invention, sleeve component can have the substantially elliptical shape of seeing in the direction of the axis that is parallel at least one through-pore.

The lateral ends that is used for the sleeve component of the 3rd embodiment can have two outer surface, this outer surface tapers to fine edge mutually at its lateral ends place, with the place combination that helps the first and second layings part to meet at each lateral ends place of sleeve component at them.

In the present invention, by overlapping application of adhesive tape films, dressing is sealed on the skin of wound circumference effectively.But term " sealing " is not definitely necessary or in fact available, and this is to comprise semi-permeable plastic material owing to form any flexible dressing thin-film material of wound cover thing, and this material is known to ordinary skill in the art.In addition, at skin with usually exist inevitably some to leak by known contact adhesive between the bonding sealing dressing materials on it, this is because the scrambling of hair and/or other skin surface and/or be not easy the defective of complete positive confinement.Be generally used on the wound and the self bonding of the TNP of sealing film on every side treatment, the type of flexible dressing stripping are known to those skilled in the art, unless and need, will here not further describe.

The dressing parts 90 of the second embodiment of the present invention represent in Fig. 4 A and 4B, and these parts can be used for any Fig. 1 and 3 sleeve component equally expediently.In this embodiment, has laying 92; Supporting course 94 and protective layer 96.Laying has lower surface 98; lower surface has adhesive coating 100; and protective layer 96 be divided into major part 102 and around and the narrow part 104 of boundary member 106 of the application of adhesive of protection center cutout 108, center cutout is the closed aperture that centers on by the laying 92 that covers binding agent at all four sidepieces.Fig. 4 B more clearly represents narrow border part 104,106.This embodiment has closed aperture 108, and crack 110 is set, so that the conduit (not shown) that is installed in the catheter component is eliminated easily.Supporting course and protective layer arrange respectively tab 112,114 again, and tab extends beyond the adhesive coated faces 98 of laying, with processing and the placement that helps dressing.

Laying 92 does not need to have therein crack 110, because this layer is retained on the patient.But crack 110 can help the manufacturing of dressing 90.

The dressing parts 90 of the second embodiment can be used for any sleeve component 10 described herein, 70.In use, in the mode roughly the same with the dressing parts 30 of Fig. 2, the adhesive coating of narrow border 106 exposes by removing little protective layer 104 and being bonded on the upper surface of flange portion 16 of sleeve component.The major part 102 of protective layer and any protective layer on the grommet member lower face then are removed, and dressing is positioned on the desired location on the patient, and press down in place.Supporting course 94 be removed at last and whole wound on dressing finish as mentioned above at last.Crack 110 helps a plurality of layers removal, and helps initial dressing parts 90 to be placed on the conduit of sleeve component.

The second embodiment of dressing of the present invention is considered to have following advantage: sleeve component is maintained on the patient skin along all four edges of flange portion, therefore further reduce any from dressing inwardly or to the probability of external leakage.

The second embodiment has also removed sleeve component has adhesive coating at its lower surface needs basically.

Comprise required sleeve component 10 or 70 and the described embodiment of dressing parts 30 or 90 can in the fabrication stage, implement, be bonded in advance on dressing parts 30 or 90 at manufacture process middle sleeve member 10 or 70 thus.In this way, protective layer can be made into the single-piece of extending in whole application of adhesive zone roughly, comprise sleeve component can or cannot application of adhesive lower surface.The in advance dressing of assembling also can arrange suitable conduit, and whole assembly is packaged in the sealing bag and sterilization by known technology.

Fig. 5 represents the 3rd embodiment of dressing sleeve component 120.In this embodiment, be parallel on the direction of port axes when the end elevation view is watched, sleeve component is overall ellipse, and comprises three apertures that separate 122,124,126, in order to receive the conduit (not shown); All apertures arrange the protruding lip seal structure 127 that is positioned at its aperture.The main body 128 of sleeve component has small tapered edge 130 in each lateral end, and wherein upper surface 132 and lower surface 134 mix mutually, with the dressing parts 142 that help to follow, 144 combination and bonding, as following describe with reference to figure 6.The sleeve component 120 of the 3rd embodiment can be for example by forming by polyurethane or by the material of for example polyethylene or polyacrylic relative stiffness is molded.

Fig. 6 A represents the first example of dressing with decomposed form, and wherein according to the third embodiment of the present invention, laying also suitably has protective layer and supporting course, and adopts the sleeve component 120 of Fig. 5.Sleeve component is with 120 expressions; The first laying part is with 142 expressions; The second laying part is with 144 expressions; Overlapping flexible strip surface is with 146 expressions; And the part of patient skin/meat is with 148 expressions (noticing that overlapping tape films 146 does not form the part of dressing of the present invention).The first laying part 142 comprises the band of the adhesive material 150 of suitable coating; OPSITE (trade mark) for example; band for example has than the transverse width of sleeve pipe 120 big-length more; for example at least 3 times; so that have favourable overlapping at the place, each end of sleeve component; folding on itself, so that when bottom protective layer 152 was removed, the surface 154 of application of adhesive was towards patient skin 148.Cut the removal that protective layer is helped bottom protective material 152 by in manufacture process, touching at 156 places.The surface 154 of this application of adhesive then is pressed against on the patient skin 148 and upper protective layer 158 is removed in order to expose the adhesive coated faces 160 of laying 142.Grommet member lower face 134 then is bonded on the adhesive surface 160.The second laying 144 is constructed similarly by the folding band 162 of suitable material equally.Bottom protective layer 164 at first is removed in order to expose the bottom adhesive coated faces 166 of the band 162 on the upper surface 132 that is bonded in sleeve component 120; and the lateral ends of the adhesive coated faces on the sleeve component either side 160,166 (not shown) mutually bonding in case between two layings 142,144 Sealed casing pipe member effectively, the sealing at the lateral ends place at sleeve component place is helped by the tapered end 130 on it.Again, by the removal that the bottom protective material is helped in cutting 170 of touching on the second laying.Top protective material 172 on the second laying can then be removed in order to expose the surface 174 of top application of adhesive, prepares to receive overlapping flexible strip material layer 146.Overlapping stripping can be made by for example OPSITE (trade mark) material again, and can cover the whole zone of wound and dressing of the present invention.Stripping has laying 180, and laying has the surface 182 of application of adhesive; The lip-deep protective layer 184 of application of adhesive; And be bonded in supporting course 186 on the surface that does not have application of adhesive 188 of laying 180.Therefore, when protective layer was removed, the surface 182 of the application of adhesive of the second laying and the surface 174 of application of adhesive were in contact with one another, in order to dressing of the present invention is sealed on the wound location environment.

Randomly laying part 144 and 142 can have the supporting course (not shown), and this supporting course can apply when finishing at laying 144 and be removed.

Touch otch 156 and choose wantonly, this is because it can whole removing remove protective material layer 152,158, but does not have otch 156, and processing can be not too easy.

The variation example of the 3rd embodiment represents that in Fig. 6 B wherein the second laying 144 changes for the band of suitable material 190, and it has the laying 192 with the surface 194 of application of adhesive; Protective layer 196; And supporting course 198.The other parts of this variant embodiment in fact can be identical with the embodiment shown in Fig. 6 A.Except when supporting course 198 is removed, only have the flat laying material face that does not have application of adhesive upwards, the assemble method step can be identical.But when supporting course 198 was removed, the table 182 of the application of adhesive of overlapping stripping was bonded on the surface 200 well.
