摘要： The present invention relates to a preparation method for porous hydroxyapatite coatings. In particular, it is a method of using suspension plasma spraying to prepare porous hydroxyapatite coatings, which belongs to the technical field of biomedical material preparations. The present invention added a pore-forming agent into the hydroxyapatite suspension with a solid content of 16%-45%. After full stirring, the feedstock materials for plasma spraying were transferred into the injection system, and injected into the high temperature area of the central plasma flame. Then, the feedstock materials made the heat exchange with the high plasma flame of plasma spraying gun. Then the sprayed raw materials were subjected to breakup and refinement of the droplets, solvent evaporation, the decomposition and gasification of the pore-forming agent and melting of feedstock materials. Finally, the porous hydroxyapatite coatings are directly deposited onto the substrate surfaces of the biomedical materials.

摘要： Deep vein thrombosis is a problem for persons who are substantially sedentary. This can be caused by an illness or trauma from an accident or in a sitting position for long period of time during long distant travel. The objective is to get motion, and an exertion into the person's legs, and particularly the feet. This is accomplished by a support that has at least one resilient unit, and preferably two such units. These units are on a support, which can be connected to the baseboard of a bed such as being an integral part of the baseboard or placed on the floor of any vehicles. The resilient units are connected and contain a fluid, which upon the application of pressure to one unit will allow fluid to flow from one resilient unit to another. The fluid preferably is heated and the pressure to be exerted to flow the fluid from one resilient unit to another can be regulated. Optimally a pump can be combined with the resilient units to pressurize the fluid and flow the fluid from one resilient unit to another to promote the person to move the fluid through the alternate pressing of the resilient units.
