技术领域Technical Field
本实用新型属于美容整形技术领域，具体涉及一种玻尿酸注射装置。The utility model belongs to the technical field of cosmetic surgery, and in particular relates to a hyaluronic acid injection device.
背景技术Background Art
玻尿酸又名透明质酸，是一种糖类物质，广泛存在于人体的结缔组织、神经组织和上皮组织中。透明质酸以其独特的分子结构和理化性质在机体内显示出多种重要的生理功能，如润滑关节，调节血管壁的通透性，调节蛋白质，水电解质扩散及运转，促进创伤愈合等。Hyaluronic acid, also known as hyaluronic acid, is a carbohydrate substance that is widely present in the connective tissue, nerve tissue and epithelial tissue of the human body. With its unique molecular structure and physical and chemical properties, hyaluronic acid displays a variety of important physiological functions in the body, such as lubricating joints, regulating the permeability of blood vessel walls, regulating the diffusion and movement of proteins, water and electrolytes, and promoting wound healing.
在整容手术中，经常需要在皮下注射玻尿酸或脂肪，玻尿酸注射是将玻尿酸以填充物的方式注入于真皮皱折凹陷或欲丰润的部位，如嘴唇、脸颊、鼻梁、下巴、疤痕等处，可达到立即性的除皱与改变容貌的效果。在对玻尿酸进行注射时，需要使用到注射器，注射器在皮下注射过程中容易刺破动静脉血管，现有的注射器缺乏提示功能，注射器一旦刺破血管，若不停止注射玻尿酸，容易导致玻尿酸栓塞，影响到整个手术的进行，而且玻尿酸注射到血管中可能会出现脑栓塞、局部皮肤科坏死、眼睛失明、下肢静脉水肿等问题。In cosmetic surgery, it is often necessary to inject hyaluronic acid or fat subcutaneously. Hyaluronic acid injection is to inject hyaluronic acid as a filler into the dermis wrinkles, depressions or areas that need to be plumped up, such as lips, cheeks, nose bridge, chin, scars, etc., which can achieve the effect of immediate wrinkle removal and face-changing. When injecting hyaluronic acid, a syringe is required. The syringe is easy to puncture arteries and veins during subcutaneous injection. Existing syringes lack a prompt function. Once the syringe punctures a blood vessel, if the injection of hyaluronic acid is not stopped, it is easy to cause hyaluronic acid embolism, affecting the entire operation. In addition, hyaluronic acid injection into blood vessels may cause cerebral embolism, local dermatological necrosis, blindness, lower limb venous edema and other problems.
