Embodiment 1

[0013] 300 mg dequalinium chloride (Solmag) and 300 mg palmitic acid (Fluka) were dissolved in 28.800 g methanol (Fluka) at room temperature. A clear solution formed. A 50 cm length of braided polyglycolide filament (USP 2.0) was dipped into the solution. Methanol was then evaporated at room temperature. Coating quality was determined gravimetrically. The coating mass was 0.6 mg.

Embodiment 2

[0015] Octenidine dichloride (Dishman Pharmaceuticals) 600 mg and palmitic acid (Fluka) 600 mg were dissolved in 28.800 g methanol (Fluka) at room temperature. A clear solution formed. A 50 cm length of braided polyglycolide filament (USP 2.0) was dipped into the solution. Methanol was then evaporated at room temperature. Coating quality was determined gravimetrically. The coating mass was 1.4 mg.

Abstract

The surgical suture material comprises an antimicrobial surface comprising fatty acid (a), octenidine dichloride and / or dequalinium chloride (b), and optionally oligomeric lactic acid ester (c). The fatty acid is chosen from lauric acid, palmitic acid and stearic acid. The low alcohol used for coating surgical suture material, is chosen from ethanol, propanol and isopropanol. An independent claim is included for coating of surgical suture material.

Description

technical field [0001] The subject matter of the present invention consists of two parts, a surgical suture material with an antimicrobial coating and a method for providing an antimicrobial coating on a surgical suture material. Background technique [0002] Based on the structure of surgical suture materials, they can be divided into monofilament and multifilament. Multifilaments can exhibit the so-called wicking effect. This refers to the migration of interstitial fluid along the filaments by capillary action. Microorganisms may also migrate with them, allowing the infection to spread along the filamentous material. Therefore, it is desirable to provide a finishing layer on surgical suture materials so that microorganisms are immobilized on the surface of the silk, thereby effectively preventing the migration of microorganisms along the silk. [0003] Braided polyglycolide multifilaments are of particular practical importance for absorbable suture materials. So far, o...
