Problems solved by technology

Among the above four patented technical solutions, the first three belong to the category of non-medical clinical disinfectant solution, which is used for disinfection and sterilization of utensils such as tableware and bathware in people's daily life, as well as cleaning and sterilization of skin (CN1262101A) , not suitable for infection control such as burns, scalds, open wounds and wounds on the human body surface
And the fourth document (CN1110557A) belongs to traumatic treatment medicine, in this document, also pointed out the advantage and disadvantage of silver sulfadiazine ointment, excellent namely its curative effect in burn surgical medication and occupies the pivotal position always The disadvantages are frequent local or systemic allergic reactions, increasing drug-resistant strains, irritating smell, inhibition of human epidermal cell growth, and adverse effects on kidney function.
However, this patented technical solution also has deficiencies. First, the treatment effect on the deep part of the wound is not ideal, because it is as impermeable as sulfadiazine silver cream; secondly, the formula has many raw materials; the processing conditions introduced are harsh

Abstract

A wound nursing liquid for controlling infection and promoting healing of wound contains proportionally Ag ion powder, gelatin, binary acid, penetrant, tartaric acid and purified water. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to a wound-protecting liquid, which is suitable for controlling infection of human body surface wounds and promoting wound healing, and also relates to a preparation method of the wound-protecting liquid, which belongs to the technical field of medical and surgical medication. Background technique [0002] At present, the medicines for wound infection caused by burns, scalds, and open wounds are mainly sulfadiazine silver cream (also known as ointment) or suspension, and its active ingredients are mainly sulfadiazine except sulfadiazine. Is a silver ion, the drug is widely used clinically. However, the following deficiencies have been exposed in clinical application: First, because this drug is not permeable, it is difficult to effectively kill the bacteria in the deep part of the wound, and it is easy to form an obvious drug film on the surface, resulting in a longer wound healing time. The second is that the wound necrotic tiss...
