Embodiment Construction

[0017] 1. Weigh the raw materials (weight ratio) according to the formula ratio: carboxymethylcellulose sodium (CMC-Na) is 0.5-10.00%, ointment base (polyethylene glycol-20000 is 10.00-30.00%, carbomer 940 is 0.2~1.75%), appropriate amount of purified water.

[0018] 2. According to the process method, weigh the raw materials according to the proportion of the formula, put the raw materials carboxymethyl cellulose sodium (CMC-Na) and polyethylene glycol-20000 into a container with purified water to fully dissolve them to form a solution ; Put the carbomer 940 raw material in another container with purified water to make it fully swollen to make an aqueous solution, then mix, stir evenly, and divide into packages.

Abstract

The invention belongs to the technical field of medical supplies, and particularly relates to a wound nursing ointment and a preparation method thereof. The wound nursing ointment consists of sodium carboxymethyl cellulose (CMC-Na) and an ointment base (polyethylene glycol-20000, carbomer 940). The microbial limit requirements of the wound nursing ointment are as follows: total number of aerobic bacteria shall not exceed 100 per mL; total number of moulds and yeasts shall not exceed 10 per mL; and Staphylococcus aureus and Pseudomonas aeruginosa shall not be detected. Components and proportion(by weight percentage) of the wound nursing ointment are as follows: sodium carboxymethyl cellulose, (CMC-Na), 0.5-50.00%, carbomer 940, 0.1-0.50%, purified water, 0.1-99%, and preservative, appropriate amount. The preparation method comprises the following steps: weighing the raw materials according to the formula proportion (by weight percentage), adding the sodium carboxymethyl cellulose (CMC-Na) and the polyethylene glycol-20000 into a container added with the purified water, and fully dissolving the sodium carboxymethyl cellulose and the polyethylene glycol-20000 to prepare a solution; adding the carbomer 940 into another container added with the purified water, fully swelling the carbomer 940 to prepare an aqueous solution, mixing the solution and aqueous solution, uniformly stirring and subpackaging. The wound nursing ointment is used for nursing care of superficial wounds such as small wounds, abrasions, cuts and the like and surrounding skin.

Description

technical field [0001] The invention belongs to the technical field of making medical supplies by using polymer materials carboxymethylcellulose sodium (CMC-Na), polyethylene glycol-20000 and carbomer 940 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. [0003] The c...
