Description
Technical Field
The invention belongs to the field of melt electrostatic spinning, and particularly relates to a preparation device of a bio-friendly medical rib fracture bandage.
Background
Electrostatic spinning is a special fiber manufacturing process, which means that polymer solution or melt is subjected to jet spinning in a strong electric field, has the advantages of simple manufacturing device, low spinning cost, various spinnable substances, controllable process and the like, and can produce nano-scale polymer filaments. The electrostatic spinning is a simple, convenient and effective novel processing technology capable of producing the nano-fibers, and can be widely applied to the fields of biomedical materials, filtration and protection, catalysis, energy, photoelectricity, food engineering, cosmetics and the like.
The traditional electrostatic spinning equipment adopts a single capillary-shaped nozzle for spinning, so that the traditional electrostatic spinning equipment is usually used for preparing solid nano fibers with smooth surfaces and single components, but the method can only obtain the nano fibers with single materials, has the problems of lack of surface specificity, poor mechanical property, difficulty in controlling degradation rate and the like, cannot obtain composite materials with various functional structures, has narrow application range, and is difficult to apply to the fields of biomedical tissue engineering and the like. In the coaxial electrostatic spinning, the feeding device is divided into a core part and a shell part, so that continuous core-shell superfine coaxial composite nanofibers can be prepared by one-time feeding, and the core layer material can be heated or dissolved to remove the core layer material, so that the shell layer material is left, and the hollow structure nanofibers are prepared. The core-shell structure nano-fiber prepared by coaxial electrostatic spinning is also increasingly used in the fields of tissue engineering, drug controlled release, solar cells and the like.
The bandage is a gauze belt for bandaging wound or affected part, is a common medical article, has many different types and multiple bandaging methods, and needs to select proper types and bandaging methods according to the wounded part. The bandages commonly used today can be divided into simple bandages, non-elastic/elastic bandages, light support bandages, stress bandages, orthopedic bandages and the like. In terms of materials, the bandages currently in use still have more or less irritation to the skin, which is not conducive to the patient using them for a somewhat longer period of time. And for different injured parts, the pressing force is also one of the key factors for recovering the injured parts, so that the medical bandage is required to have proper elasticity and have requirements on no stimulation to the human body and the like.
