Problems solved by technology

In practice, the known absorbent articles have proven to be very useful, but their absorption efficiency still needs to be enhanced, especially for the discharge of exudates from moderately or heavily infected wounds, so that they can be more effectively removed from the deep wound surface. absorb wound exudate

Embodiment Construction

[0171] Figure 1a and 1b A schematic view of a portion of an absorbent article 100 comprising a liquid-absorbent inner layer 1 and a liquid-permeable perforated cover layer 2 is shown. The inner layer 1 comprises a cellulose-like carrier material 3 and two two-dimensionally structured cellulose-like jacket layers 4.1, 4.2, only the inner core, the carrier material 3, is permeated with osmotically active superabsorbent polymers, i.e. superabsorbent particles 20 . The cellulose jacket layers 4.1, 4.2 are bonded without adhesive to the carrier material 3, that is to say they are bonded together in a two-dimensional manner by compressive forces.

[0172] The cover layer 2 is made of polypropylene fibres, comprising two suitable liquid-permeable rectangular plates 2.1, 2.2 connected at their edges by ultrasonic welds 6. The layer 1 thus positioned in the covering layer occupies the area defined by the weld seam and corresponds to about 75% of the area of ​​the plates 2.1, 2.2 in ...

Abstract

The invention relates to an absorptive element that is to be mounted on human or animal skin surfaces in the area of wounds. Said absorptive element is composed of an outer coating (2) that is permeable to liquid substances and an inner layer (1) which is enclosed by the coating (2) and substantially comprises a mixture of an amount of osmotically highly active substances and an amount of osmotically relatively weak or inactive substances, such as cellulose. The inner layer (1) is filled with osmotically active substances in such a way that an osmotic pressure, via which the wound fluid contained in a wound can be removed from the organism that is to be treated, can be applied to the wound with the wound fluids contained therein, thus supporting interstitial normohydration in both the superficial wound region and in the deep tissue by the fact that the body's own fluids are directed into the absorptive element in the direction of flow thereof towards the patient's skin surface and are retained there.

Description

technical field [0001] The present invention relates to an absorbent article for application to wound areas on the surface of human or animal skin, comprising an outer cover layer permeable to liquid substances and an inner layer surrounded by said outer cover layer, said inner layer comprising a certain amount of permeability A mixture of strong active substances with a certain amount of less permeable active or inactive substances such as cellulose. Background technique [0002] An absorbent article of the aforementioned type has been disclosed in the applicant's patent DE10059469. In practice, the known absorbent articles have proven to be very useful, but their absorption efficiency still needs to be enhanced, especially for the discharge of exudates from moderately or heavily infected wounds, so that they can be more effectively removed from the deep wound surface. Absorb wound exudate. Contents of the invention [0003] The objects of the present invention can be a...
