Adjustable skin micro roller pin device with synchronous ejection administration function

Abstract

The invention discloses an adjustable skin micro roller pin device with a synchronous ejection administration function. The skin micro roller needle device comprises a bracket, a handle, a roller pinbucket and a protective cover, the bracket comprises a fixing seat, a rotating shaft and a rotary joint, the rotating shaft comprises a connecting end and a free end, and the connecting end is connected with the fixing seat; one end of the rotary joint is rotatably connected to the fixing seat; the other end of the rotary joint is connected with the free end; the handle is disposed on the fixing seat; the roller pin bucket includes a roller and a plurality of needles, the roller sleeves outside the rotating shaft, the needles are disposed on the roller, and the function of adjusting the lengthof the exposed needles is achieved; the protective cover is disposed on the bracket, and the protective cover is connected with a spraying device to spray the medicine into a roller pin operating area. The adjustable skin micro roller pin device with the synchronous ejection administration function can reduce the risk of infection and is safer and more sanitary; a quantitative and sprayable administration system is arranged, which can conduct administration on the roller pin operating area and can reduce the inconvenience of manual application; meanwhile, spray administration can reduce the risk of secondary infection caused by artificial smearing.

Description

technical field [0001] The invention relates to an adjustable skin micro-needling device with the function of synchronous spraying and drug delivery. Background technique [0002] Transdermal drug delivery is a common treatment method in dermatology and cosmetology. The "mesoderm therapy" that directly introduces drugs into the deep dermis by stimulating the skin with micro-rolling needles is widely used in medical cosmetology for its safety, effectiveness and convenience. widely used in the world. However, the microneedle used in mesotherapy is only composed of a simple roller and a handle. The microneedle on the roller has a fixed needle length and cannot be adjusted immediately for different parts and different lesions. The imported medicine needs to be instilled by an assistant with a syringe or manually applied, resulting in uneven administration, limited amount of medicine infiltrated and waste of medicine, and also greatly increases the chance of infection. In addit...

AI Technical Summary

Problems solved by technology

However, the micro-needle used in mesotherapy is only composed of a simple roller and a handle. The micro-needle on the roller has a fixed needle length and cannot be adjusted in real time for different parts and different lesions.

The imported medicine needs to be dripped or manually smeared by an assistant with a syringe, resulting in uneven administration, limited amount of medicine infiltrated and waste of medicine, which also greatly increases the chance of infection

In addition, due to different operating techniques (mainly pressure), it is difficult to accurately guarantee the depth of treatment and the intensity of stimulation to the dermis, and complications such as coloration, scratches, and even scars will inevitably occur. also limited

[0003] To sum up, just satisfying the skin irritation and manual drug application cannot achieve the precise goal. Not only that, but the one-time skin rolling needle will also cause waste. Accurate and convenient operating environment
