23 Jul Device for preparing polylactic acid and calcium phosphate composite microspheres
Abstract
The utility model discloses a device for preparing polylactic acid and calcium phosphate composite microspheres. The device comprises a first supersonic oscillator connected with the discharge end of a grinding machine through a first pipeline and communicated with a second solution mixing box through a second pipeline, the discharge end of the first supersonic oscillator is communicated with a second supersonic oscillator through a fourth pipeline, the second supersonic oscillator is communicated with a third solution mixing box through a third pipeline and communicated with a magnetic mixing unit through a fifth pipeline, a water pipe is mounted on the magnetic mixing unit, the magnetic mixing unit is communicated with a recirculated water evacuating device through a sixth pipeline, and the recirculated water evacuating device is communicated with a drying box through a seventh pipeline. The utility model has the benefits that powdered polylactic acid/calcium phosphate microspheres can be prepared by adopting the solvent evaporation method, and the demands on raw materials used for preparing a tissue engineering scaffold by adopting the selective laser sintering technology are satisfied.
