Sodium carboxymethylcellulose liquid dressing and preparation method thereof

Abstract

The invention discloses a sodium carboxymethylcellulose liquid dressing and a preparation method thereof, which belong to the technical field of medical supplies. The sodium carboxymethylcellulose liquid dressing is prepared from sodium carboxymethylcellulose (CMC-Na), purified water and a preservative. The microbial limit requirements are as follows: the total number of aerobic bacteria per 1mL does not exceed 100; wherein the total amount of molds and saccharomycetes is not more than 10 per 1mL; staphylococcus aureus and pseudomonas aeruginosa cannot be detected. The sodium carboxymethylcellulose liquid dressing comprises the following components in parts by weight: 0.5-50.00% of sodium carboxymethylcellulose (CMC-Na), a proper amount of purified water, and a proper amount of the preservative. The preparation method comprises the following steps: weighing the raw materials (weight ratio) according to the formula ratio, putting the raw materials sodium carboxymethylcellulose (CMC-Na)and the preservative into a container added with the purified water, fully dissolving to prepare a solution, uniformly stirring the materials, and performing sub-packaging to obtain the product. A protective layer is formed on the surface of a wound surface, so that the physical barrier effect is achieved. The dressing is used for nursing superficial wounds such as small wounds, scratches and incisional wounds and surrounding skin.

Description

technical field [0001] The invention belongs to the technical field of making medical supplies by using polymer material carboxymethylcellulose sodium (CMC-Na), purified water and preservatives as main raw materials. Background technique [0002] Damage to the superficial skin surface such as skin wounds and wounds is a common phenomenon in people's normal life. Once a wound occurs on the skin, measures must be taken to prevent infection of the wound surface. The degree of contamination of the wound itself has a lot to do with whether infection occurs in the future. Generally speaking, wounds are classified as follows: 1. Clean wounds (Clean-Wounds) --- No inflammation. 2. Clean-contaminated wounds (Clean-Contaminated Wounds) --- No obvious contamination. 3. Contaminated wounds (Contaminated Wounds) --- Acute inflammation, but no suppuration. Traumatic wound with necrotic tissue. 4. Infected wounds (Dirty or Infected Wounds) --- Infected wounds.
