Abstract: A preparation method for a non-spherical hydrogel microparticle embolic agent is provided. The method includes: alternately injecting a oil phase solution and an aqeuous phase solution into an elongated channel, the aqueous phase solution contains a water-soluble polymer to be cross-linked, the aqueous phase solution has a cross-linking reaction in the elongated channel to obtain a product, which is then discharged from the elongated channel to obtain the non-spherical hydrogel microparticle embolic agent. This preparation method is simple in process, and the non-spherical hydrogel microparticle embolic agent obtained from this method has good embolization performance.

Abstract: The disclosure relates to a mixing device and a liquid mixing method. The mixing device comprises a first clamping assembly, a second clamping assembly and a driving assembly, the first clamping assembly is used for fixing a first container containing a first liquid, the second clamping assembly is used for fixing a second container containing a second liquid, the first container and the second container are in communication, the driving assembly drives the first liquid and the second liquid to flow back and forth between the first container and the second container to complete a predetermined degree of mixing to form a third liquid. The flow speed of the first liquid and the second liquid driven by the driving assembly is accurately controlled, so that an iodized oil emulsion with better physical and chemical characteristics is prepared, and an emulsion with better emulsifying effect and treatment effect is obtained.
