Abstract

The cooling element has medium-guiding tubes (3) that are connected with a base material (1) along a longitudinal axis of the tubes by looped threads (2) e.g. embroidery and/or sewing threads, where the cooling element is made of textile material. The base material corresponds to a body part e.g. knee joint, wrist joint and ankle joint. The threads and the tubes are made of sterilizable hypoallergenic material. A cooling medium flows through the tubes. Cooling zones (4) are arranged on an elastic textile structure.

Description

The The invention relates to a textile cooling structure for Medical and therapeutic purposes, in particular for the use for demand-controlled temperature control of acute bone fractures is provided under the plaster.

Problem and state of the art

DE202007004072U1 discloses as a purely passive system an invention intended to avoid hypothermia of body parts. However, for certain medical purposes, meaningful use of targeted hypothermia may, for. B. can be achieved by coolable conditions. Coolable supports such as welded polyethylene bags (Hegewald, Lichtenberg, Germany) are not permeable to water vapor and drape only limited. The same applies to DE9304015U1 , Especially since here by transverse walls or webs a directional control of the medium flowing through is achieved, but not a local differentiation of cooling zones takes place. DE000001934228U discloses a compress composed of a compartmented bag. The chambers are interconnected and filled with paraffin.

In addition, these pouches are not suitable for under-gliding use because their mediocre medically necessary position-fixed immobilization in the cast of the fracture is impossible. This also applies to the bandage DE000008016728U1 , which is filled with a liquid at the temperature of use, gelatinous or plastic heat or cold-storing medium. With this passive temperature control system, an active control and influencing of the tempering effect is not possible. Furthermore has DE000008016728U1 a circular handling of the refrigeration point to the destination. However, due to the swelling occurring in fractures, these may not be enclosed / wound circularly, but must be split, as well as the plaster cast after initially circular Anwickeln. Also the device GB000002403418A (Cooling vest) does not allow for a variation of the temperature control and must therefore be removed from the patient from time to time. Thus, this device is not suitable for the Untergipseinsatz.

As an active system is in WO002005082301A1 a device for cooling the facial area described. Here, the connections for the cooling medium in the context of the invention are expedient, for a but not anyway intended submerged insert inexpediently far apart. Likewise shows DE102007022967A1 a device for tempering the body of a patient with a thermal storage element described.

Farther textile warp knit constructions are known with knitted Hoses (cooling vest, climatic curtain) in which the hose diameter is at least 5 mm. In these large-scale Structures are the hoses depending on the type of use stretched longitudinally or meandering incorporated into the warp knit structure. The common Disadvantage of the design principle warp knit is that the beginning and the end of the media-carrying hoses (z. B. flow and return) to the opposite Pages or spatially far away. These Construction leads to the intended mobile Use of a subsurface cooling cuff in the medical Everyday impractical connection solutions.

One Another disadvantage of warp knit construction is that one Hose insertion not in the backward direction is possible. This can not be zones with increased Hose density and thus increased cooling effect generate, in which the hoses circular, spiral or in a labyrinth shape.

approach

The The object of the invention is a coolable structure for sub-glacier deployment, which differentiated locally Has cooling zones arranged arbitrarily on a base and can be fixed and have connection elements that lie close together and protrude beyond the basic structure.

Solved This object is achieved by the features specified in claim 1. Advantageous embodiments are in the subclaims contain.

Advantages of the solution

By the use of textile hypoallergenic and elastic, prefabricated Backing materials will be an excellent fit as well achieved a water vapor permeability and skin friendliness.

One Another advantage in particular for the handling in Clinical everyday life represents the fact that the tubes spatially close to each other lying away from the cuff can be used without the need for connecting elements. The hoses are self-closing valves can be connected to an external temperature control unit. By the Self-closure can be the highest hygienic requirements are met.

The Positioning of the cooling zones on the textile surface is freely selectable and can therefore be used for different purposes Cooling tasks on different body parts be optimally adapted. The flat structure and elastic Component of the textile allows a severing of the plaster layer (so-called Spaltgips), an increase in volume as a result of swelling to enable. The hoses are like this arranged that they completely cut through the Association layers are not damaged. By the low The strength of the cooling sleeve becomes the reduction result and the stability of the plaster cast is not called into question or negatively affected.
