Abstract

The invention provides a processing method for accelerating dispersion of an injection type filler by utilizing a negative pressure means. The processing method comprises the following steps: an accommodating step of accommodating a mixture containing a solvent and the injection type filler in a first accommodating space of a first accommodating device; a sealing step of sealing the first accommodating space; the vacuum auxiliary mixing step of forming negative pressure in the first containing space, forming flowing of the solvent in the first containing space through floating and breaking of bubbles, and restoring the first containing space to the pressure before the negative pressure is formed. The colloid solute is uniformly dissolved in the solvent and the dispersoid is uniformly dispersed in the solvent by repeating the vacuum-auxiliary mixing step. According to the processing method, the bubble structure formed in the injection type filler can be destroyed, so that the solvent enters the bubble structure to be mixed with the injection type filler, the time required by dispersion of the injection type filler is 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 negative pressure. 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 suspensi...
