Problems solved by technology

At present, my country has been able to independently produce ventilators and related plastic products, but due to factors such as product fineness, the products are mainly used in small and medium-sized cities and vast rural areas or exported, while the markets of big cities such as Beijing, Tianjin and Shanghai are mainly used abroad. Imported products, so the market space is still very large

Abstract

The invention discloses a preparation method of a polyvinyl chloride material used for medical trachea cannulas. The preparation method comprises following steps: step 1, by weight, ingredients are delivered into a high speed mixer for 20 to 40min of stirring and mixing; and step 2, an obtained uniformly mixed material is delivered into a double-screw extruder for fusion, plasticizing, extrusion, and pelleting so as to obtain the polyvinyl chloride material. Preparation method flow is relatively short; operation is simple; cost is low; the preparation method is friendly to the environment, and is high in economic benefits. Compared with the prior art, the polyvinyl chloride material used for medical trachea cannulas possesses excellent biocompatibility and safety, and performance better than that of related products on the market.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a preparation method of a polyvinyl chloride material for medical endotracheal intubation. technical background [0002] As a very important material, plastic has been widely used in the medical and health field. It can be made into disposable medical equipment such as drip bottles, syringes, etc., and can be used in non-disposable medical equipment such as gauges, surgical instruments, etc. The field of medical plastics is currently one of the most promising markets in the plastics industry. [0003] With the continuous growth of the global population, especially the aging population and the increase in the number of people suffering from chronic diseases, the continuous growth of the medical service market has been promoted, and special medical devices have been widely demanded. Due to the excellent characteristics of polymer materials and the ability to reduce costs, at presen...
