Abstract

1. A portable device in the form of a textile-integrated protective system and the design of the device as a garment or its arrangement within a garment for passive hemostasis in the case of penetrating injuries, wherein the device has several chambers (1) containing a hemostatic material and which tear open upon mechanical perforation so that the material escapes into a wound, wherein the chambers (1) or chamber modules with one or more chambers (1) are permanently integrated or modularly interchangeable in a carrier material, and wherein the device has an inner side facing towards a body and the chamber(s) (1) are tearable at least in the direction of the inner side and the hemostatic material is automatically released upon penetrating injuries.

Description

The present invention relates to a portable device in the form of a textile-integrated protective system according to the preamble of the first claim. The invention is not limited to the features defined in the patent claims. Rather, further technical embodiments are described which are not claimed but are fully disclosed in order to provide alternative or supplementary embodiments. The invention lies at the intersection of medical emergency equipment, personal protective equipment (PPE) and textile technology and is intended in particular for applications in military, governmental and civilian risk situations. Hemostatic materials are known from the state of the art, for example based on kaolin, chitosan, silver ions or bioactive nanostructures, which are usually available in the form of compresses, gel pads or applicators. For example, in the printed publication EP 1731175 B1 Hemostatic cross-linked dextran beads are described, which are used for rapid blood clotting and hemostasis. They can be administered via creams, lotions, and/or emulsions and may be contained in a matrix- or reservoir-type transdermal patch. In the printed publication EP 3 785 753 B1 A device for dispensing a hemostatic powder is disclosed, comprising an elongated hollow reservoir. A manual air pump is attached to the reservoir, and a discharge port is located at the distal end of the reservoir. A porous filter is provided, which is slidably arranged in the reservoir between the air pump and the discharge port. Furthermore, a spring is arranged in the reservoir between the air pump and the filter. The powder is located in the reservoir between the filter and the discharge port, and the pump is in fluid communication with the discharge port through the porous filter and the powder. The printed matter DE102016009877A1 The diagram reveals the structure of a "React Protect Package." A wound dressing is applied to the center of the package, and/or a cushion/spring padding is placed on top of the dressing to cushion the wound from pressure on sensitive and injured skin, absorb moisture (from the dressing), and better filter contaminated skin (from the dressing/filter layer). The barrier/insulating layer can be the next layer to protect the ingredients from the environment during application and to allow them to be absorbed until they dry and take effect on the open or irritated skin. Following this, the dressing/dispensing chamber can be inserted, containing the Space Puck or cannula-type dispensing dressing compartment, which may contain the antiseptic, herbal cream mixture, and nitrogen. The Space Puck may have three further fine chambers that can dispense the antiseptic and/or the nitrogen and/or the herbal cream mixture first. All ingredients, materials and substances (components) mentioned in the React Protect Plaster can also be used variably, in many ways, and combined as desired in the React Protect Package. A skin or wound dressing is also mentioned in the printed text. DE 10 2017 125 281 A1 The device is disclosed. As its name already indicates, it is applied to areas of the body to be treated that already have a wound. The device comprises an active ingredient and at least two chambers for storing at least two substances, which can be opened by mechanical means so that, after opening the chambers, the liquids are miscible and can be transferred into a carrier for the active ingredient. Also in print EP 3 661 570 B1 A wound dressing for treating a tissue lesion is described. The wound dressing comprises a first layer made of a fluid-impermeable material and at least partially fenestrated, and a second layer made of a fluid-impermeable material and at least partially fenestrated, wherein the second layer is coupled to the first layer to define a chamber between the first and second layers; and a third layer arranged within the chamber, wherein the third layer comprises a distributor with a central region and a perimeter region, the perimeter region containing perforations arranged in a pattern defining a plurality of sub-regions of the perimeter region, wherein the first layer and the second layer are detachably coupled to each other near their outer edges by a plurality of welds or bonds through the perimeter region of the third layer comprising the distributor. These products therefore require manual application by medical professionals. Personnel or first responders. Furthermore, concepts for smart textiles for controlled drug delivery or the integration of sensors have been researched, for example in the form of surgical dressings or reactive hydrogel textiles. However, these systems are not suitable for immediate hemostasis in traumatic, penetrating injuries under mobile or tactical conditions. In particular, the state of the art lacks a textile-integrated or modular system that can be effective over a large or the entire body area in the event of an injury. The invention is based on the objective of providing a portable dev
