Abstract

The invention provides a processing method for accelerating dispersion of injection type filler by means of pressurization. The processing method comprises the following steps: a providing step; an accommodating step; a connection step; a preliminary mixing step; and a reciprocating pressure mixing step. A solvent and a mixture are respectively accommodated in the first accommodating device and the second accommodating device and are communicated through a connecting device; then the flow velocity of the mixture is increased and shear force is formed to prevent colloid solute or dispersoid from gathering by repeatedly pressurizing in a reciprocating manner; thus, the colloid solute is uniformly dissolved in the solvent, and the dispersoid is uniformly dispersed in the solvent. Compared with a vortex generator, the processing method for accelerating dispersion of the injection type filler by utilizing a pressurizing means can provide larger shearing force. Therefore, the injection type filler can be prevented from gathering, the dispersion time of the injection type filler can be shortened, and the dispersion effect and stability of the injection type filler can be improved.

Description

technical field [0001] The invention relates to the field of filler dispersion, in particular to a processing method for accelerating the dispersion of injection-type fillers by means of pressurization. Background technique [0002] Injectable poly (D, L-lactic acid) (injectable poly-D, L-lactic acid, PDLLA) is a new injectable filler that stimulates collagen proliferation, and can be injected into human soft tissue , so as to achieve medical cosmetic effects such as wrinkle removal, contour modification or tissue plumping. The PDLLA filler contains PDLLA microspheres (microspheres) and hydroxymethylcellulose (CMC). PDLLA microspheres are ingredients used to stimulate collagen proliferation, but they are insoluble in solvents for injection (such as distilled water for injection). Hydroxymethyl cellulose is a water-soluble polymer that can be dissolved in a solvent for injection to form a colloidal solution, thereby increasing viscosity, providing dispersion and suspension ...
