A preparation device for composite viscoelastic

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 of a composite viscoelastic agent. Background technique [0002] The main component of viscoelastic agent is sodium hyaluronate (first extracted from umbilical cord, then from 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), the excipients include sodium chloride, disodium hydrogen phosphate, potassium dihydrogen phosphate. Its main function is that clinicians serve as surgical pads for ophthalmological microsurgery, which temporarily supports the operation space, so that tissues are free from mechanical damage by surgical instruments and facilitate the smooth implementation of the operation. It is mainly used for cataract surgery. Later cataract is a common and important complication of cataract surgery. The main method of treatment for later cata...

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, drugs that kill or inhibit cell growth, promote cells from the basement membrane Drugs detached from the basement membrane, drugs that promote the detachment of cells from the basement membrane, non-toxic or low-toxic substances with color or fluorescence, currently there is no very convenient way to quantify the various components of the composite viscoelastic in the market Preparation device for blending, mixing and stirring and automatic filling
