A kind of medical tissue protective cleaning liquid and its preparation method and application

Abstract

The invention relates to a degradable medical tissue protective cleaning solution and its preparation method and application. The protective cleaning solution is a colorless, transparent, viscous liquid, which includes three components. The first component is hydrophilic and antibacterial The raw material mainly refers to chitosan derivatives, and its weight percentage is 0.1%-10%; the second component is hydrophilic and moisturizing raw materials, mainly referring to starch derivatives, and its weight percentage is 0.5%-5%; the third component is a physiological balance solution, mainly referring to 0.9% sodium chloride and PBS phosphate buffer saline; the three components are formed by physical stirring and mixing.

Description

technical field [0001] The invention belongs to the field of biodegradable polymer materials, and in particular relates to a medical tissue protection cleaning solution and a preparation method and application thereof. Background technique [0002] In the process of surgical operation and wound treatment, medical workers often adopt various measures, such as hemostatic agent, anti-inflammatory agent, wound irrigation agent, etc. Currently, the commonly used medical tissue cleaning solution is sodium chloride injection. Good sex, clean and pollution-free, is of great significance for debridement during surgery. But sodium chloride injection still has weak point as medical cleaning liquid, for example has no moisture retention, lubricity and bacteriostasis. [0003] At present, if some skin wounds need cleaning, infection prevention and postoperative adhesion prevention, antibiotics, sodium hypochlorite, polyaminopropyl biguanide (polyhexamethylene), sodium carboxymethylcellu...

AI Technical Summary

Problems solved by technology

[0006] It is well known that a humid and hypoxic environment is crucial to the wound healing process, but a humid environment is often accompanied by aggravated bacterial infection. Bacteria are more likely to survive and reproduce in a humid environment, while survival and reproduction in a dry environment are average. greatly reduced

[0007] Since the existing technology cannot meet the clinical requirements, it is of great importance to develop a new medical tissue protective cleaning solution with moisturizing, lubricating and antibacterial effects
