Description

Technical Field

[0001] The utility model belongs to the technical field of gel dialysis equipment, and in particular relates to a dialysis system of cross-linked sodium hyaluronate gel. Background Art

[0002] After cross-linking modification, sodium hyaluronate forms a hydrogel, namely cross-linked sodium hyaluronate gel, which is a special dispersion system in which colloidal particles or polymer molecules are linked to each other to form a spatial network structure, and the gaps in this network structure are filled with liquid. The cross-linked sodium hyaluronate gel has the characteristics of swelling but not dissolving due to the formation of a covalent cross-linked network. Due to the presence of a large number of hydrophilic groups in this hydrogel, it can absorb and store a large amount of water, causing its weight and volume to increase significantly.

[0003] Chinese patent application No. 2023209207219 discloses a dialysis device for cross-linked sodium hyaluronate gel, including an outer barrel, an inner barrel, a sieve plate, a liquid guide tube 1, and a liquid guide tube 2. Through holes are provided on the barrel wall and the bottom plate of the inner barrel, the sieve plate is laid on the upper surface of the bottom plate of the inner barrel, the inner barrel is suspended inside the outer barrel through the upper end eaves, one end of the liquid guide tube 1 is placed in the cavity between the inner barrel and the outer barrel, and the other end extends to the outside of the outer barrel, one end of the liquid guide tube 2 is plugged into the plug hole on the bottom plate from the bottom of the inner barrel, and the other end extends to the outside of the outer barrel, and the end of the liquid guide tube 1 located outside the outer barrel and the end of the liquid guide tube 2 located outside the outer barrel are connected by a hose, a peristaltic pump is installed on the hose, and the outer barrel is filled with dialysate. When in use, the dialysate forms a circulating flow path, which effectively shortens the dialysis time and significantly improves the purity quality of the cross-linked sodium hyaluronate gel product compared to the traditional static dialysis method, thereby ensuring the dialysis efficiency of the cross-linked sodium hyaluronate gel.
