Medical sodium alginate hydrogel dressing

The invention belongs to the field of biomedical materials. The invention relates to a medical sodium alginate hydrogel dressing and a preparation method of the medical sodium alginate hydrogel dressing. 15 to 35 parts of modified sodium alginate; 3-5 parts of a reaction type organic base; the novel sodium alginate medical hydrogel dressing material is obtained through spinning, UV curing and freeze-thaw cycle physical cross-linking by taking sodium alginate as a raw material and 3-5 parts of a photoinitiator as a raw material. The preparation of the novel sodium alginate medical hydrogel dressing not only effectively solves the problems of low breaking strength and high brittleness of the existing sodium alginate medical hydrogel dressing, but also has efficient antibacterial performance, and in addition, the adsorption resistance of the novel sodium alginate medical hydrogel dressing can avoid secondary damage caused by dressing replacement in the actual use process. 本发明属于生物医用材料领域。本发明涉及一种海藻酸钠医用水凝胶敷料及其制备方法，该
