Description

Technical Field

[0001] The utility model relates to the technical field of composite viscoelastic preparation, and more specifically, to a composite viscoelastic preparation device. Background Art

[0002] Viscoelastic is a colorless, transparent gel solution composed of high-purity sodium hyaluronate and physiological buffered balanced salt. Viscoelastic is a transparent gel-like substance used for intraocular surgery, which has viscosity and elasticity and can be used to maintain the anterior chamber space, protect intraocular tissues and assist surgical operations. In the preparation process of the composite viscoelastic, it is necessary to place a variety of raw materials and additive powders into the preparation device and mix and stir with the solvent to form a uniform gel-like substance. During use, the existing composite viscoelastic preparation device usually directly places the raw materials and additives into the preparation tank and stirs and mixes with the solvent, so that the raw materials or additives are concentrated into the solvent, which is not easy to mix quickly and evenly, and the mixing time needs to be extended, thereby reducing the work efficiency of the composite viscoelastic preparation; secondly, during use, the existing composite viscoelastic preparation device, due to the high viscosity of the composite viscoelastic, when the prepared composite viscoelastic is discharged, a large amount of composite viscoelastic will adhere to the inside of the preparation tank, thereby wasting resources and affecting the subsequent use of the preparation tank.
