Description
本实用新型涉及微针结构技术领域，具体涉及一种微针调节结构。The utility model relates to the technical field of microneedle structures, in particular to a microneedle adjustment structure.
透皮给药是指在药物透过皮肤表面给药。药物穿过皮肤各层的屏障，经毛细血管吸收进入体循环产生全身或局部治疗作用。这种透皮给药方式在原理上与皮下注射或静脉输入给药是同一类投药方法，但是比起传统注射给药方式具有更加无痛，更加安全、稳定和病人适应性好的优点。在透皮给药技术中，药物依靠药物的浓度梯度做为驱动力，渗透扩散透过皮肤进入血流产生药效，扩散速率取决于穿过角质层的浓度梯度以及药物分子的大小和亲水性。但是由于皮肤对大多数药物的渗透性很低，通过被动扩散能够有效地穿过皮肤发挥药效的药物很少。为增进药物透皮渗透性，人们开始采用机械方法使皮肤角质层产生微孔和破裂。Transdermal administration refers to administration of drugs through the skin surface. The drug passes through the barriers of various layers of the skin and is absorbed into the systemic circulation through capillaries to produce a systemic or local therapeutic effect. This transdermal drug delivery method is in principle the same type of drug delivery method as subcutaneous injection or intravenous infusion, but it has the advantages of being more painless, safer, stable and patient adaptable than traditional injection drug delivery methods. In transdermal drug delivery technology, the drug relies on the concentration gradient of the drug as the driving force, and the penetration and diffusion through the skin enters the bloodstream to produce a drug effect. The diffusion rate depends on the concentration gradient across the stratum corneum and the size and hydrophilicity of the drug molecule. Sex. However, due to the low permeability of the skin to most drugs, there are few drugs that can effectively pass through the skin to exert drug effects through passive diffusion. In order to improve the transdermal permeability of drugs, people began to use mechanical methods to produce pores and rupture of the stratum corneum.
其中微针透皮给药技术被证明是最有效的基于机械方法的透皮给药。微针透皮给药技术结合皮下注射与透皮贴片的双重释药优点，借助一种带有许多微小突起的器件作用于皮肤造成皮肤最小程度的微孔创伤，药物通过所创造的微孔可增加药物的渗透性，特别是对于大分子药物的渗透起到很大的促进作用。当使用可溶解的生物可降解材料来制作微针时，药物和生物分子可混入到微针本身内。在应用过程中，可溶解的微针结构在皮肤内快速溶解，从而释放药物和生物分子，所以不存在带尖头的废物。Among them, microneedle transdermal drug delivery technology has proved to be the most effective transdermal drug delivery based on mechanical methods. Microneedle transdermal drug delivery technology combines the advantages of subcutaneous injection and transdermal patch dual release, with the help of a device with many tiny protrusions acting on the skin to cause minimal pore damage to the skin, the drug passes through the created pores It can increase the permeability of drugs, especially for the penetration of large molecule drugs. When using soluble biodegradable materials to make microneedles, drugs and biomolecules can be mixed into the microneedles themselves. In the application process, the soluble microneedle structure quickly dissolves in the skin, thereby releasing drugs and biomolecules, so there is no pointed waste.
由于个体皮肤厚度和皮肤弹性的差异，使用时留在皮肤表层的不能被溶解的微针针体中上半部分的比例不同，造成每次注射的时候可被吸收的微针药量是不同的，所以很难精确控制微针的给药量。Due to the difference in individual skin thickness and skin elasticity, the ratio of the upper half of the insoluble microneedle needle body that remains on the skin surface during use is different, resulting in different amounts of microneedle medicine that can be absorbed during each injection , So it is difficult to accurately control the amount of microneedles administered.
但现有的微针调节结构，结构复杂，准确性差，而调节固定不准确，难于对微针穿刺深浅度的精度控制。However, the existing microneedle adjustment structure has a complicated structure and poor accuracy, while the adjustment and fixing are inaccurate, making it difficult to accurately control the penetration depth of the microneedle.
