Device for preparing composite viscoelastic substances

Abstract

The invention discloses a device for preparing composite viscoelastic substances. The device comprises a tank. The tank is a cube, first hydraulic rods are arranged in the middles of six inner side surfaces of the tank and are perpendicular to the corresponding inner side surfaces of the tank, the ends of fixed rods of the first hydraulic rods are fixedly connected with the inside of the tank, a hollow sphere is arranged between the inner ends of the six first hydraulic rods, two perpendicular annular grooves are formed in each outer side surface of the hollow sphere and include a horizontal annular groove and a perpendicular annular groove, power sleeves are fixedly mounted at the ends of movable rods of the first hydraulic rods and are coaxial with the center lines of the corresponding first hydraulic rods, the inner ends of the power sleeves deeply extend into the corresponding annular grooves, and power wheels are mounted at the inner ends of the power sleeve and can be matched with the inner bottom surfaces of the corresponding annular grooves in a contact manner. The device has the advantages that the composite viscoelastic substances can be blended at first proportions, canbe comprehensively stirred and can be automatically accommodated, and accordingly procedures for preparing the composite viscoelastic substances are simple and are high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation devices, in particular to a preparation device for composite viscoelastic agents. Background technique [0002] The main ingredient of the viscoelastic agent is sodium hyaluronate (first extracted from the umbilical cord, then extracted from the cockscomb, and now mostly produced by fermentation, the chemical name is: (1-4)-O-β-D glucuronic acid-(1- 3) -2-acetylamino-2-deoxy-β-D glucose), excipients include sodium chloride, disodium hydrogen phosphate, potassium dihydrogen phosphate. Its main function is for clinicians to use it as a surgical pad for ophthalmic microsurgery, to temporarily support the surgical space, to protect the tissue from mechanical damage by surgical instruments, and to facilitate the smooth implementation of surgery. It is mainly used for cataract surgery, and posterior cataract is a common and important complication of cataract surgery. The main treatment for...

Problems solved by technology

How to prevent and treat post-cataract has become one of the key issues to completely solve cataract blindness. Viscoelastic agents are needed in cataract surgery. At present, viscoelastic agents used in surgery include sodium hyaluronate and chondroitin sulfate, etc. The role of cataract, in order to solve these problems, a composite viscoelastic agent, including sodium hyaluronate and other viscoelastic carriers that meet the pharmacopoeia, dru
