Medical hygienic materials are special functional materials used in medical procedures and in direct or indirect contact with human tissues. Therefore, for medical hygiene polymer materials, especially implantable medical polymer materials, they should meet the properties of non-toxicity, chemical inertness, histocompatibility, blood compatibility, resistance to biological aging, sterilizability, non-carcinogenicity, and ease of processing, in order to ensure the safety of the materials for the human body.
PA material has similar amide structure with natural human body component protein macromolecules, has good biocompatibility, and is not easy to make the cells of living organisms produce stimulation signals.
In addition, it has good chemical stability and controllable mechanical properties, etc. At the same time, cells can be adsorbed on the surface of PA materials. All these special properties make PA medical and healthcare materials, especially implanted PA materials, play a favorable role in reducing the mass, changing the mechanical properties, and especially in facilitating the establishment of mutual mechanical effects between implanted PA materials and the human body.
Due to its excellent mechanical strength, high abrasion and corrosion resistance, and good biocompatibility, PA is widely used as a medical catheter and other healthcare materials. Medical catheters are soft, hollow tubes that are inserted into the body to aid in urine drainage or used as wire guides for various applications in the diagnosis and treatment of heart disease and gastrointestinal disorders.PA medical catheters are also used in intravenous drips and can be prepared mainly from PA6, PA66, PA11 and PA12.
Based on the feature of PA materials, as well as medical and hygienic requirements, BAOD Extrusion has introduced suitable extrusion designs after continuous testing and research. Taking into full consideration of the precision of medical catheters and the requirements of high-speed production, it greatly reduces the rate of material waste and the rate of defective products. Through the automatic roll changing device and automatic cutting and collecting, etc., it saves the labor cost and makes the enterprise benefit maximized.
