Magnesium and its alloys have good mechanical properties and biocompatibility as well as bio-de- gradability,which are potential to be a new class of medical implant materials.

Use and management of medical implanting material;

Current situation of waterproof ﹠moisture permeablefabric and its application in medical materials;

Because of high bio-activity, good property of physical, hemostasia, high water absorbability and antibacterial Performance,antibacterial alginate/gelatin blend fiber,made by nature biodegradable material,has been used as medical materials.

With the development and creation of medical technology, use of new medical equipments and application of new techniques, medical materials have been widely used in diagnostic and therapeutical fields in hospitals.

To analyze the specific weight that medical material cost in medical service cost and patient s expenditures and suggests it would be better to strengthen the whole management of medical material, speed up the information management of medical material,build up the cost accounting management to reduce medical service cost.
