Vacuum drying device for preparing medical polymer material

Abstract

The invention discloses a vacuum drying device for preparing a medical polymer material and belongs to the technical field of medical polymer. Supporting seats are arranged on the left side and the right side of the top of a base respectively; two groups of supporting rods are symmetrically arranged on the top of the base; a fixed rod is arranged on the right side of a vacuum pump; an output shaftis fixedly connected with the fixed rod through a barrel; a connection rod is arranged at the middle part of an inner cavity of the barrel; a feeding pipe is arranged on the top of the barrel; and ashunting plate is arranged at the bottom of the inner cavity of the barrel. The vacuum drying device for preparing the medical polymer material is simple in structure, convenient to operate and strongin practicability. By adopting the vacuum drying device for preparing the medical polymer material, through the mutual matching of the vacuum pump and an exhaust tube, the inner cavity of the barrelis evacuated into a vacuum state; the inner cavity of the barrel can be rapidly dried through a drying machine and the shunting plate; and the barrel is driven by the motor to rotate to be matched with a spiral vane, so that the medical polymer material can be comprehensively dried and is prevented from being incapable to be used due to uncompleted drying.

Description

technical field [0001] The invention relates to the technical field of medical polymers, in particular to a vacuum drying device for preparing medical polymer materials. Background technique [0002] With the development of the population aging process, the number of patients with cardiovascular diseases in our country is increasing year by year, and the demand for medical polymer materials is increasing day by day. Medical polymer materials refer to polymer materials used to manufacture human internal organs, external organs, pharmaceutical dosage forms and medical devices, and their sources include natural biopolymer materials and synthetic biopolymer materials. Natural medical polymer materials come from nature, including cellulose, chitin, hyaluronic acid, collagen, gelatin and sodium alginate, etc.; synthetic medical polymer materials are chemically synthesized polymer materials for medical use At present, polyurethane, silicone rubber, polyester fiber, polyvinylpyrrol...

AI Technical Summary

Problems solved by technology

Natural medical polymer materials come from nature, including cellulose, chitin, hyaluronic acid, collagen, gelatin and sodium alginate, etc.; synthetic medical polymer materials are artificially synthesized medical polymer materials through chemical methods At present, polyurethane, silicone rubber, polyester fiber, polyvinylpyrrolidone, polyether ether ketone, polymethyl methacrylate, polyvinyl alcohol, polylactic acid, polyethylene, etc. are commonly used in the preparation process of medical polymer materials. It needs to be dried, but the traditional drying is done by a heater, because the ordinary dryer not only dries the medical polymer material, but also dries the air in the drying box. The heating and drying efficiency and speed are not very ideal, resulting in some waste of medical polymer materials, which cannot meet the needs of use. At present, there is an urgent need for a drying equipment that can meet the needs of use. Therefore, we propose a A vacuum drying device for preparing medical polymer materials
