Medical composite dressing and preparation method thereof

Abstract

The invention discloses a medical composite dressing and a preparation method thereof. The medical composite dressing is made of fabrics such as non-woven fabrics or cotton fabrics as carrier materials, soaked in a mixture composed of carboxymethyl chitosan solution, sesame oil, and beeswax, taken out, packaged in inner packaging bags, and finally irradiated and sterilized. have to. The medical composite dressing has the following advantages: (1) Contains carboxymethyl chitosan, sesame oil and beeswax and other healing-promoting ingredients, which have a significant effect on promoting wound healing; (2) The carrier material endows the film dressing with a certain degree of flexibility and strength. , easy to peel and paste, easy to operate, no adhesion to the wound surface, no secondary damage; (3) It has the functions of keeping moist, antibacterial, and reducing scar formation. The medical composite dressing is a moist composite dressing that can significantly promote wound healing, and is suitable for the treatment of surgical wounds, abrasions, burns, skin donor sites, decubitus ulcers, diabetic ulcers and other difficult-to-heal wounds.

Description

technical field [0001] The invention relates to a medical composite dressing and a preparation method thereof, belonging to the field of biomedical materials. Background technique [0002] Trauma is the damage caused by normal skin (tissue) under the action of external injury factors. Common traumas include surgical incisions, abrasions, burns, donor sites, decubitus ulcers, vascular ulcers of lower extremities, diabetic ulcers, and other difficult-to-heal wounds. The formation and existence of wounds will have a significant impact on local and even systemic functions of the body. In order to accelerate the healing of the wound and reduce the infection of the wound surface, dressings are generally used to cover and protect the wound. [0003] An ideal medical dressing should have the following properties: (1) maintain a moist environment on the wound surface, which is conducive to wound healing; (2) can effectively absorb wound exudate and reduce infection; (3) not only ha...

AI Technical Summary

Problems solved by technology

Since the wound healing process is a complex process, different wounds and different stages of the same wound have different requirements for dressings, so currently no single material can meet the complex needs of the wound healing process

For example, most of the dressings made of natural materials have good absorption, good biocompatibility and biological activity, but poor mechanical properties; synthetic polymer materials have good insulation properties and good mechanical strength, but their absorption properties are relatively poor compared to natural materials some
