Wound dressing

Tissues are known as wound textiles, with which the sheet-like structure adheres to the wound surface when it is approached of wound moisture, in particular wound secretion, pus, blood and the like should be prevented or at least weakened. In the case of a known fabric, the threads or thread parts of the fabric shrink, lengthen differently or swell Ingress of wound moisture and thereby lead to mutual Movements that reduce or prevent the threads or thread parts from sticking to one another and to the wound.

To achieve the same effect as stated above, a knitted fabric has been proposed in which a strong thread

is tied in by a thin thread in mesh, with the strong thread twisted up, straight or in a slightly offset standing shot and bound by at least one minimally twisted thread is. The strong twisted thread has the dimension 34/2 and the minimally twisted thread the dimension 4o / l on. In this known knitted fabric, the so-called "tunnel effect", ie the lifting of the knitted fabric from the Wound, i.e. not sticking to the wound, is caused by twisted threads, i.e. crepe threads are combined with weakly twisted single threads, the high-twisted threads S-twist direction and the have soft-twisted threads Z-twist direction.

The object of the present invention is to create a wound dressing which allows the sheet-like structure to be glued with the wound surface when wound moisture enters, in particular wound secretion, prevents or at least weakens and which can be controlled without the use of twisted threads Has lift-off effect and is highly secretive at the same time.

A wound dressing material is proposed to solve this sewing up, which according to the invention is designed in the manner is that the wound dressing made of a knitted fabric with Ffiden a Z-yarn or S-yarn, which are equally strong and have the same prehuna.

The knitted fabric can also be S-twisted or Z-twisted Have dimen & lon and rotation. The threads of the knitted fabric are made made of rayon or bleached cotton as a fiber material.

According to a further feature of the invention, the knitted fabric has threads made of Z-yarns or S-yarns with a matching the particular desired lifting effect lying more or less strongly above the usual twist used in warp yarns Turn on.

The knitted fabric has threads with dimensions of Nm 3o / l, Nm 34/1, Nm 4o / l, Nm 5o / l and the like or Nm 3o / 2, Nm 34/2, Nm 4o / 2, Nm 5o / 2, Nm 7o / 2 and the like. on.

The threads of the knitted fabric can be made from cotton yarns with minimum values for σ £, such as

a) for Nm 3o / l oC = Ho

b) for Nm 34/1 aC = Ho

c) for Nm 4o / l <yC = 115

d) for Nm 5o / l oC = 118 and the like.

or from rayon yarns with minimum values for C, such as

a) for Nm 3o / l oC = 92

exist.

MitoC let denotes the twist coefficient according to DIN 6o 912.

The wound dressing is designed such that of the Threads Ll, L2, L3, L4 the thread Ll forms the stitch, while the threads L2, L3, L4 as slightly or strongly offset wefts are inserted.

According to a further feature of the invention, stitches with the basic bonds, such as open fringes 2.ο - ο.2 or ο.2 - 2.ο, closed fringe 2.ο or o.2, open jersey o.2 - 4.2, closed jersey 2.ο - 2.4 as well as known types of bindings, such as cloth, atlas bindings and the like.

In order to increase the pore volume and the cushioning effect, the knitted fabric is roughened on the side facing away from the wound.

With that formed according to the invention and of the same type A wound dressing material is created by existing knitted threads

with not only a lifting effect but also a very high absorbency and thus a high secretion retention capacity is achieved? Properties due to knitted fabrics made from highly twisted twisted threads and weakly twisted single threads cannot show their structure. Because the knitted fabric in all guide rails Ll, L2, L3, L4 uses the same yarn possessed, i.e. dimension, direction of rotation and amount of rotation through which the controllability of the lifting effect is achieved, are the same, the high lift-off effect is achieved. Are Z-yarns or S-yarns used that have a twist that is more or less strong (high) over the usual yarn twists (warp twists = moderate rotation), the lifting from the wound develops to a greater or lesser extent.

In the drawing, the object of the invention is shown as an example, namely shows:

In all of the exemplary embodiments shown in the drawing, a cartridge with four layers of threads has been assumed. However, it is also possible to work with more or less thread layers if a corresponding knitted fabric is to be obtained. In all exemplary embodiments, the same designations have been used for the threads, namely Ll, L2, L3, L4. All threads have the same dimensions, the same direction of rotation and the same amount of twist. Preferably, Z-yarns are used which have a twist that is more or less strong than the usual yarn twist for warp yarns. S-yarns can also be used. The knitted fabric can also have S-twisted threads or Z-twisted threads of the same dimension and twist. The structure is designed so that the thread Tl forms the loop, while the threads L2, L3, L4 in the knitted fabric in leic ^! ii or strongly staggered shots run. As Ma-

The following basic ties are possible:

as well as all known Tuch _T Atlas bindings etc.

The guide rails for the threads L2, L3 and L4 can be as follows Perform shot variations:

L3 ο.ο - ο.ο ο.ο -2.2 ο.ο - 4.4 ο.ο - 6.6

L4 ο.ο - 2.2 ο.ο - 4.4 ο.ο - 6.6

To increase the pore volume and the cushioning effect is the knitted fabric roughened on the side turned away from the wound.

7638740 oi.09.77

All threads L1, L2, L3 and L4 are equally strong; they have the same warp twist and the same dimensions, e.g. Nm 3o / l, Nm 34/1, Nm 4o / l or heavier or can be lighter and is therefore based on the height of the m weight. Twists Nm 3o / 2, Nm 34/2, Nm 4o / 2, Nm 5o / 2, Nm 6o / 2 and the like can be used, which can have both an S and Z rotation. As fiber material can Both rayon, bleached cotton or a mixture of cotton and rayon are used.

The threads of the knitted fabric can be made of cotton yarn with minimum values for oC ι such as

a) for Nm 3o / l σ £ = Ho b) for Nm 34/1 o ^ = Ho c) for Nm 4o / l cyf = 115 d) for Nm 5o / l oC = 118 and the like exist.
