Description

Novel microneedle adjusting structure

Technical Field

The utility model relates to a micropin technical field, concretely relates to novel structure is adjusted to micropin.

Background

Transdermal administration refers to administration of a drug through the skin surface. The drug passes through the barriers of the skin layers and is absorbed into the systemic circulation via the capillaries to produce a systemic or local therapeutic effect. The transdermal administration mode is the same type of administration method as subcutaneous injection or intravenous infusion administration in principle, but has the advantages of being painless, safer, more stable and good in patient adaptability compared with the traditional injection administration mode. In transdermal drug delivery techniques, the drug relies on the concentration gradient of the drug as the driving force, and the rate of diffusion depends on the concentration gradient across the stratum corneum and the size and hydrophilicity of the drug molecules, with osmotic diffusion through the skin into the bloodstream producing the drug effect. However, since the skin has low permeability to most drugs, there are few drugs that can effectively exert their effects through the skin by passive diffusion. To enhance the transdermal permeability of drugs, mechanical methods have been used to create micropores and cracks in the stratum corneum of the skin.

Among them, the microneedle transdermal delivery technique has proven to be the most effective transdermal delivery based on mechanical methods. The microneedle transdermal drug delivery technology combines the advantages of subcutaneous injection and the dual drug release of a transdermal patch, and the device with a plurality of tiny protrusions acts on the skin to cause the minimal micropore wound of the skin, so that the drug can increase the permeability of the drug through the created micropores, and particularly plays a great role in promoting the permeation of macromolecular drugs. When soluble biodegradable materials are used to fabricate the microneedles, drugs and biomolecules may be incorporated into the microneedles themselves. During application, the dissolvable microneedle structures dissolve rapidly in the skin, releasing the drug and biomolecules, so there is no spiked waste.

But current novel micropin is adjusted structure is used by adjusting pole and casing cooperation basically, because adjust pole and casing screw assembly and adjust, uses for a long time to adjust the pole and appear not hard up phenomenon easily, and leads to adjusting rocking of pole when using, and when adjusting the pole, often appears adjusting the pole and drops, and the landing is on the ground to lead to the damage of adjusting the pole and being infected with the bacterium, and the structure is complicated, installs loaded down with trivial details. The present invention has been made to solve the above problems.
