Problems solved by technology

The first step in wound treatment is to rinse the wound. Currently, the commonly used flushing solution is physiological saline, but the function of normal saline is single, and it does not have the functions of anti-inflammatory, antibacterial, hemostasis, and promotion of tissue cell regeneration.
The preparation of chitosan into irrigation fluid is also widely used in clinical practice, but chitosan is made of animal-derived materials, which has poor biocompatibility and high safety risk

[0023] Preparation process: Dissolve oxidized cellulose with alkaline solution according to the formula listed in the table, add a certain amount of water for injection, adjust the pH to neutral with acidic solution, then add 0.9g sodium chloride, 0.033g diphosphate Potassium hydrogen phosphate and 0.067g disodium hydrogen phosphate, and finally make up to 100ml with water for injection, measure the pH value, filter, fill the filtrate, fill it with nitrogen, seal it, and get it.

preparation example

[0025] Preparation example for adjusting the amount of sodium chloride and pH buffering substances added: Weigh 2g of oxidized cellulose powder (carboxyl content 20%), add 40ml of sodium hydroxide solution with a mass concentration of 0.01g / ml, and stir to dissolve; after the dissolution is complete Add 30ml of water for injection, then adjust the pH to neutral with a nitric acid solution with a volume concentration of 0.5%; add sodium chloride, potassium dihydrogen phosphate and disodium hydrogen phosphate in sequence, stir and dissolve fully, and finally make up to 100ml with water for injection, and measure pH value, filtering, filling the filtrate, filling with nitrogen gas, sealing, and the product is ready. The addition amount of sodium chloride, pH buffer substance is shown in Table 1.

Abstract

The present invention relates to a novel plant polysaccharide protective flushing solution mainly composed of oxidized cellulose, which comprises the following components: 0.1%-5% by weight of oxidized cellulose, and 0.8%-1.0% by weight sodium chloride, 0.01% to 0.1% by weight of pH value buffer substances and the rest of water for injection; the pH range of the novel plant polysaccharide protective flushing solution is 6.5 to 7.5. The novel plant polysaccharide protective rinsing solution provided by the invention has the functions of rinsing wounds, hemostasis, antibacterial, promoting wound healing and anti-adhesion, has good stability and is not easy to degrade.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a plant polysaccharide protective flushing solution mainly composed of oxidized cellulose. Background technique [0002] All kinds of trauma, such as knife wounds, traffic accidents, bleeding trauma, ulcerative trauma, etc., should be treated in time. Improper handling will cause wound bleeding, infection, suppuration, etc. The first step in wound treatment is to rinse the wound. Currently, the commonly used flushing solution is physiological saline, but the function of normal saline is single, and it does not have the functions of anti-inflammatory, antibacterial, hemostasis, and promotion of tissue cell regeneration. It is also widely used clinically to formulate chitosan into irrigation solution, but chitosan is made of animal-derived materials, which has poor biocompatibility and high safety risk. [0003] Oxidized cellulose is made of natural cellulose, which i...
