Abstract

The invention relates to a pasty preparation for forming a semirigid dressing, said preparation having the following formulation: 30-70% by weight water, 1-10% by weight gelling agent, 10-40% by weight glycerol or polyvalent alcohols, in particular propylene glycol or sorbitol, 0-30% by weight oil, 0.5-5% by weight water-soluble salts, 0.5-2% by weight rheological fillers, and 1-5% adsorbent fillers.

Claims (28)

1. A paste-like preparation for forming a semirigid dressing comprising the following formulation:

30-70% by weight of water,

1-10% by weight of gelling agent,

10-40% by weight of glycerol or polyhydric alcohols,

0-30% by weight of oil,

0.2-5% by weight of water-soluble salts,

0.2-2% by weight of rheological fillers, and

1-5% by weight of adsorbent fillers,

wherein the preparation is a zinc-free preparation.

2. The preparation as claimed in claim 1 , wherein the formulation further contains 0.05-0.5% by weight of metals and/or metal compounds that have an antimicrobial action.

3. The preparation, of claim 2 , wherein metals or metal compounds that have an antimicrobial action are silver and/or copper.

4. The preparation as claimed in claim 1 , wherein the gelling agent is a water-soluble polymer selected from the group consisting of gelatin, starch derivatives, cellulose derivatives, alginates, acacia, agar, and mixtures thereof.

5. The preparation of claim 1 , wherein the oil is a paraffinic and/or olefinic oil.

6. The preparation of claim 1 , wherein the rheological fillers are selected from the group consisting of aluminum oxide, magnesium oxide, silicon dioxide, and mixtures thereof.

7. The preparation claims of claim 1 , wherein the adsorbent fillers are selected from the group consisting of activated carbon, cyclodextrin, finely dispersed silica, and mixtures thereof.

8. The preparation of claim 1 , wherein the preparation has a viscosity of 30-6000 mPas at 60° C.

9. The preparation of claim 1 , wherein the adsorbent fillers are dispersed in powder form in the paste-like preparation.

10. The preparation of claim 1 , wherein it is yellowish, beige, gray or black in color.

11. A semirigid dressing set consisting of a strip-form textile carrier and a preparation of claim 1 .

12. A method of treating states and conditions selected from the group consisting of venous thrombosis, swelling caused by injuries or impairment of venous function, chronic venous insufficiency, including venous leg ulcers and phlebedema, thrombophlebitis, phlebothrombosis, fractures of the fibula without deformity, distortions, luxations, tendovaginitis, further treatment after plaster casts, reduction of post-traumatic edema, for rapid decongestion and elimination of chronic edema, phlebitis of deep and superficial veins, post-thrombotic states, aftercare of bone fractures, and mixtures thereof, wherein the method comprises employing the paste-like preparation for forming a semirigid dressing of claim 1 .

13. A semirigid dressing preparation comprising a strip-form textile carrier to which the preparation of claim 1 is applied.

14. The semirigid dressing preparation as claimed in claim 13 , wherein the textile carrier is coated or impregnated or coatable or impregnatable with the preparation.

15. The semirigid dressing preparation of claim 13 , wherein the textile carrier is selected from the group consisting of a woven fabric, knitted fabric, crocheted fabric or nonwoven fabric.

16. The semirigid dressing preparation or semirigid dressing set as claimed in claim 13 , wherein the textile carrier is elastic.

17. The semirigid dressing preparation as claimed in claim 13 , wherein the weight ratio of carrier to preparation is from 1:3 to 1:6.

18. A compression, support or relief bandage comprising the semirigid dressing preparation of claim 13 .

19. A method for producing a semirigid dressing preparation of claim 13 , wherein the preparation is applied to one or both sides of the strip-form textile carrier material.

20. A semirigid dressing obtained from a semirigid dressing preparation of claim 13 , wherein the water at least partly evaporates from the preparation within 12-48 h as a result of which the bandage is less flexible than prior to evaporation.
