Abstract

The present invention relates to a wound care article adapted to different through-flow speeds of the wound exudate.

Description

Birgit Riesinger

Wound care products adapted to different flow rates of

wound exudate

The present application relates to a wound care products, adapted to different flow rates of wound exudate.

The goal is to design a new wound care products, in which the

Flow rate of the exudate is adapted to needs of the wound. The wound care article should preferably with sorbion plus (wound spacer grid) to be equipped. Also, two flat sides forming the shell, as with SANA may consist of Sorbion PLUS.

The wound care article has at least one layer (or block) of rubber, silicone rubber or other hydrophobic perforated material. The material can be porous or non-porous. It may be present at least one layer of a porous and at least a further layer of a non-porous material. Further, the use of Hyaluronsäre, z. As in powder form, is provided.

The inner material can be made (with air bubbles) from at least one location of the air foil, wherein perforations are provided between the air bubbles, which also warming

have properties. The air foil may be at least partly thermally bonded with the wound facing away from the shell wall. A loose arrangement of the air foil with or without perforations out of the question. As a non-porous materials such as metal foils may be also punched. The

Metal films may be to a different material (eg. As foam rubber) is laminated.

The thermal insulating properties of the Wundpfiegeartikels can be obtained from staple fibers by at least one layer of a cotton fabric. The cotton staple fibers have a length of 2 to 30 mm, are "rotated", that is not straight and are provided with axial holes (hollow fiber). Therefore, suitable for a very fluffy arrangement, z. B.

between two non-woven PP films (such as the shell of the sorbion sachet). This cotton fabric can be sprayed and to a shell wall and stuck there.

Further, the interior may have different rigidity. For example:

inhomogeneous material, material of different thickness, different materials, embossments in the selected region, etc. A tamponade with a wound spacer grids (eg Sorbion PLUS) may have a micro fiber core, to a catheter or suction valve.

If a layer of Polyurtehan (PUR) foam (layer) placed on the Sorbion PLUS (without gluing) and the negative pressure is generated, the smooth top of the S ORB ION PLUS creates the wound to close, wherein the polyurethane foam protrudes, ie creates an air cushion between these materials. This may be because that the adhesive force of the smooth top of the sorbion plus the Wundoberfiäche greater than the force generated by the negative pressure.

The interior may be different "channels" or ramified. A hole (channel) may have a cascade or bell-shaped formed wall. The channel may also be branched off, as shown on the sketch z. B.. Figures

In Fig. 1 a coated inner layer 1 of a wound care product is shown, which consists of two interconnected surface connected plies 1.1, 1.2 of which the position of 1.1 to as "upper", ie wound facing away from and the other layer are referred 1.2 "lower" as, wound-facing can. The covering of liquid-permeable polypropylene nonwoven with dashed line

(Reference number 2) are indicated. A through hole 3 includes a round, elastic

Pivoting flap 4, dependent on their position relative to the hole 3 by the amount of consistency and flow rate of wound exudate. The inner layer has a plurality of holes 3 and pivoting flaps. 4

As shown in FIGS. 2, 4 takes the pivoting flap only a part, in terms of area about half of the hole cross-section away. The pivoting flap 4 passes into an annular sheet-like insert 5, which in turn is placed in a round, flat seat. 6 The seat 6 is connected to the lower layer 1.2, and concentrically incorporated opposite to the hole. 3 Such an arrangement of the insert 5 ensures a secure fit for the located within the hole 3

Pivoting flap 4. In another, not shown embodiment, the pivoting flap on a surface that is only slightly smaller than the hole cross section, such as a throttle valve

is the internal combustion engine.

The layers 1.1, 1.2 are made of solid, medical grade latex. Optionally, a flat absorbent body can be at least (not shown) within the envelope 2 may be used, optionally with super absorbent substance and powdered

Hyaluronic acid (hyaluronate) is added. The hyaluronate can also be added to the latex. The hyaluronate promotes the healing process, accelerates cell proliferation that requires significant amounts of liquid.

FIG. 3 illustrates a solid inner layer 7 made of silicone rubber, comprising a plurality of cup-shaped holes 8 (in figure 8 is only one hole shown). For the inner layer a hot cross-linked (HTV) silicone rubber was selected containing - advantageously - organic peroxides for crosslinking. The material has a density of 0.45 g / cm 3.

FIG. 4 shows an inner layer 9, consisting of an upper, sore remote location 9.1 and a lower layer 9.2, in which a channel system 10 is installed. As the material of the plies 9.1, 9.2 a finely structured, cross-linked polyethylene foam is of hypoallergenic

Features selected. The PE foam is closed cell and not

absorbent, therefore, an additional superabsorbent absorbent body is also provided, which is within a common sheath (not shown).

The channel system 10 is composed of a through hole 1 1 and four branched off from the hole 1 1, crosswise (see. Fig. 5) opposite to the hole extending channels 12.1, 12.2, 12.3, 12.4, of the hole starting at first along a surface 14 the lower layer 9.2 and then perpendicular to the surface. Fig. 6 illustrates the arrangement of the channels after removal of the upper layer 9.1. There are four molded in the material of the lower layer 9.2, elongated grooves 13.1 to see 13.2, 13.3 and 13.4 belonging to the

Channel system 10 includes. Another channel system (reference numeral 15) is shown in FIG. 12. Here, 18 is a continuous well but ramified hole 16 is incorporated in the material of an inner layer. At the hole 16, lateral, diagonally arranged channels 17.1, 17.2 connected to. As the material for the inner layer 18 of nylon fine-pored foam is provided.

Another possibility of controlling the flow is shown in FIG. 7, which shows a sheet-like primary dressing 19th The primary dressing 19 ( "wound spacer grid") consists of a pliable, thin section of film 20 of polyethylene, which is arranged in the present case with a plurality of peripherally lying round perforations 21 and centrally provided mutually parallel incisions pairs 22 each Einschnitten-. pair 22 forms consisting of two horizontal parallel cuts, two rectangular

Pivoting flaps 23.1, 23.2 (see. Fig. 8) and an intermediate, likewise rectangular hole 24, which may increase as a result of the flow of wound exudate (see. Fig. 9). All perforations 21 and pivoting flaps 23.1, 23.2 are punched and therefore just.

Figures 10 and 1 1 show a sheet-like, peripherally bonded with a wound 26

Wound cover 25, a cover 25 located between the wound and the wound 26

Inner layer 27 and a primary dressing 28 which has been described in WO 2007/118652 of the applicant.

The primary dressing 28 is placed with its smooth surface 29 on the wound so that its crater-shaped perforations 30 face towards the wound covering 25th The primary dressing 28 is located on the wound so that between its smooth surface and the wound, at least a small free space 33 (see FIG. FIG. 10) has remained.

The wound cover 25 is provided with a not shown suction head and with a suction hose 31 with valve 32nd

Is the vacuum used (see. Fig. 11), the wound spacer grids laying on the surface of the wound 26 and smooth the entire surface and adheres there. This is achieved in that the adhesive force of the smooth surface 29 of the wound-distance grid is slightly greater than the force that is generated by the negative pressure. Between the inner layer 27 and the wound spacer grid is formed of an air cushion 34 (see FIG. FIG. 1 1).

The complete covering of the wound through the wound distancing grid can fully exploit its hemostatic properties. Wound healing is accelerating.

The primary dressing 28 and 19 may be preferably enriched with pure titanium dioxide and other known hemostatic and wound healing-promoting substances.

Figures 13, 14, 15 and 16 show, inter alia, an air cushion sheet 35 which is used in the illustrated therein Wundpfiegeartikeln. To ensure the breathability or permeability of such an air cushion film for the wound exudate is located between the air bubbles 36 are perforations 37 (cf. 16, Fig.) Is provided.

In Fig. 13, a prefabricated, areal, simpler wound care article 50 is shown having a sheathed portion 38 of the air cushion Slide 35. The envelope 2 consists of an upper wound covering 39 made of PP non-woven and the lower wound-facing, already described primary dressing 28 (wound spacer grids). The object of the bubble wrap 35 to keep the wound area for a long time warm.

In Fig. 14, a wound care article 60 is shown. Referring to FIG. 14, the bubble film 35 with the upper PP nonwoven (wound covering 39) fully bonded such that the air bubbles 36 are facing downwards (the direction of the wound). A lower shell wall 40 is made of a PP non-woven fabric 41 and the thermally coupled to the PP-non-woven fabric 41 primary dressing 28 (see FIG. Detail Z, Fig. 14). Between the upper wound covering 39 and the lower shell wall 40, a center shell wall 42 is also provided from PP nonwoven. The two casing walls 40, 42 include an inner layer 43 in the form of an airlaid mat of superabsorbent substances. The Wundpfiegeartikel 60 may be bonded to the wound. To this end, an encircling adhesive strip 44 is provided with a removable protective strip 45th

In Fig. 15, a wound care article 70 is shown which is stick to the wound over the adhesive strip 44. The Wundpfiegeartikel 70 has an inner cladding 46 made of PP non-woven and a

Outer shell 47. The outer shell 47 is composed of an upper shell wall 48 and the lower primary dressing 28 together. In turn, the upper shell wall 48 consists of an outer PP-non-woven fabric 49 and the surface thermally connected to the PP-non-woven fabric 49 bubble wrap 35th

The inner wrapper 46 includes a perforated inner layer 51 made of PUR foam. Optionally, a 52, indicated vacuum system (dashed lines, Fig. 15) is provided.

If the outer PP-non-woven fabric 49 (not shown) may be replaced by an air-tight wound covering, there would be an upper shell wall 48 with double air cushion.
