Description

Technical Field

[0001] The utility model relates to the field of stirring equipment, in particular to a stirring equipment. Background Art

[0002] Polysaccharide materials such as sodium hyaluronate, chitosan, carboxymethyl cellulose, trehalose, etc. are generally composed of multiple monosaccharide molecules connected by glycosidic bonds. They have long molecular chains, high polymerization degrees, and many side chains carry hydroxyl groups, which are easy to form intermolecular hydrogen bonds. When dissolved in water, they are easy to form aggregates and difficult to dissolve into a uniform viscous solution in a short time. The larger the molecular weight, the more difficult it is to dissolve. Such polysaccharides are often used as gel matrices or drug carriers for implantable medical devices due to their excellent biocompatibility. For ease of use, the materials are usually stirred evenly and then filled into syringes for use. However, the traditional production process usually involves transferring the stirred materials to a degassing device for vacuum degassing treatment, and then transferring them to a filling device for filling.
