Benefits of technology

[0014]The advantage for the patient of using medical products according to the invention lies in the more rapid wound healing, in the reduction of the pain associated with wound treatment, in the shorter time spent in an inpatient department, and in the fact that the cost of treating such wounds is considerably reduced, which is important to the economy. These advantages are achieved by adapting the structural and mechanical properties of the medical product to the properties of the tissue in question.
[0017]Mechanical signals in the form of the exertion of a controlled pull on the cells in the wound bed can represent an important activator of the wound response. Mechanical influences on the wound also play a part in collagen genesis because modified stresses during wound closure influence scarring. It is assumed that in order to form a normal collagen architecture a defined physiological mechanical stimulation is required with respect to loading and orientation. In the case of scar tissue, by contrast, the anisotropy of the collagen network and the dimensions of the collagen fibers are increased.

Problems solved by technology

However, this product does not promote angiogenesis.

Embodiment Construction

[0028]A spacer layer 11 with high shear force takeup consisting of gel-modified yarns permits absorption and desorption and the mechanical binding of the compress material. The shear force takeup permits the distribution of local pressure loads, that is to say it has a cushion function and permits stress distribution, which leads to uniform loading of the wound surface and thus avoids negative local stresses. Lastly, the compress 1 has an embroidered layer 12. The fabric 11 is designed as a spacer in relation to the antibacterial layer 10 and as a material which takes up exudate. On this fabric 11, which is advantageously formed as a knit, lies the separately produced embroidered layer 12 which is preferably connected at its side edges to the compress 1, for example by ultrasonic welding. Reference number 13 denotes stimulation points which are formed in the layer 12, particularly in the embroidery technique. In the form represented, they form flat to semi-round protuberances, stimu...

Abstract

The present invention relates to a medicinal product with a textile component such as a wound compress having a surface containing a multiplicity of openings arranged in at least two hole patterns. The diameter of one opening of one hole pattern deviates from the diameter of an opening of another hole pattern by about at least a factor of 5. Better wound healing is achieved by adapting the structural and mechanical characteristics of the medicinal product to the characteristics of the target tissue.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a medical product with a textile component, for example a wound compress, having the features of a multiplicity of openings, with at least two patterns of holes with groups of openings, the diameter of one opening of one hole pattern deviating from the diameter of an opening of another hole pattern in each case by about at least a factor of 5 from one another.[0003]2. Description of the Related Art[0004]In the medical sector, a number of textile products are known which are intended to externally promote wound healing, for example. Known medical products such as wound compresses consist for example of woven fabric, which has the disadvantage that it has a hard surface which adapts poorly to the wound. For this reason, many wound compresses are made up of knitted fabrics which are soft per se. They also have some degree of moisture absorbency. The softness of knitted fabrics arises from the movem...
