Example Embodiment

[0007] The present invention provides a method for preparing a silver-loaded calcium alginate medical dressing, which comprises the following steps: take 100 grams of deionized water, stir in a high-shear mixer and add 1-3 grams of elemental silver compound containing elemental substance The silver compound is a solution with silver content of 1500-2500PPM, which is quickly stirred and dispersed evenly, and then added Tween 20 to continue stirring. The use amount of Tween 20 is 2-3 grams, and slowly add it under continuous stirring. 5-10 grams of carbomer, put the semi-viscous colloid in a container for later use, and then take 100-150 grams of calcium alginate fiber soak it in the semi-viscous colloidal solution, and place it in a centrifuge for dehydration , Dried, dehydrated and completely soaked in chemically pure acetone, then placed in a centrifugal dryer for dehydration, placed in a drying temperature above 50-60 degrees, and dried to make a dressing, which is a sterile c...

Abstract

The invention discloses a preparation method of silver-carrying calcium alginate medical dressing. The preparation method comprises the following steps: stirring and adding 1-3g of a compound containing single substance silver to 100g of deionized water in a high shear stirrer; quickly stirring and uniformly dispersing; then, adding tween 20 and continuing stirring; slowly adding 5-10g of Carbomer under a state of continuously stirring to obtain semi-pasty colloid for later use; then, dipping 100-150g of calcium alginate fibers in the semi-pasty colloid liquor; then, dehydrating and drying to prepare the dressing. According to the invention, sterilizing and bacteria-resisting single substance silver is added into the calcium alginate fibers to solve specific problem that drug resistance is easy to generate for various medicines. The preparation method is simple, convenience and efficient.

Description

technical field [0001] The invention relates to a preparation method of a silver-loaded calcium alginate medical dressing. Background technique [0002] At present, clinically, the main treatment of wound bacterial infection is to use various drugs for treatment. This method is commonly used frequently and is prone to drug resistance. Contents of the invention [0003] The invention discloses a preparation method of a silver-loaded calcium alginate medical dressing, which adopts calcium alginate fiber to add elemental silver to sterilize and antibacterial, and is simple, convenient and quick to solve the specific problem that various drugs are easy to produce drug resistance. [0004] The present invention adopts the following technical scheme: a preparation method of silver-loaded calcium alginate medical dressing, which comprises the following steps: take 100 grams of deionized water, stir and add 1-3 grams of elemental silver-containing compound, make it quickly and ev...
