Abstract

The utility model relates to the field of medical science, in particular to a drug delivery device for gold microneedles, which comprises a storage shell for accommodating gold microneedles, wherein when the limiting rod drives the abutting ring to abut against the positioning ring, the tension spring is in an expanded state, the abutting ring abuts against and is fixed to the top of the positioning ring through the expansion force of the tension spring, when the positioning ring and a needle head at the bottom of the positioning ring need to be disassembled and cleaned, the abutting ring moves upwards until contacting with the inner top of the support frame through pulling the limiting rod and simultaneously contracting the tension spring, then the positioning ring has no abutting force, the positioning ring is lifted upwards to separate the positioning ring from the storage shell, and then the positioning ring moves to one side, so that the positioning ring and the needle head can be disassembled.

Description

Gold microneedle is with device of dosing Technical Field The utility model relates to the field of medical science, in particular to a drug delivery device for gold microneedles. Background The medical treatment refers to the treatment process of improving, repairing or enhancing the appearance, skin quality, body morphology and the like of a human body by combining medical means and technical means with medical expertise, wherein a gold microneedle penetrates through the surface layer of the skin to directly deliver the medicament into the skin or deeper tissues. Through retrieval, the utility model of the integrated transdermal drug delivery device based on drug storage and microneedles, which is disclosed by the utility model, can facilitate the personnel to detach the microneedles by arranging the dismounting mechanism, thereby facilitating the personnel to clean and replace the microneedles, facilitating the personnel to use, and solving the problem that the microneedles in a comparison document are arranged in the drug storage unit, are inconvenient to detach independently by the personnel, and cause more complicated cleaning and maintenance. Above-mentioned although utilize dismouting mechanism to be convenient for change the washing to the microneedle, the gag lever post in the dismouting mechanism is connected through grafting mode and gag lever post hole and is fixed a position the microneedle of mounting panel below, from this can see that the gag lever post receives the exogenic action easily and moves in the gag lever post downthehole down in the use, leads to the gag lever post to break away from the gag lever post hole when using easily, and then leads to the problem of microneedle stability in the use. Therefore, a drug delivery device for gold microneedles is proposed to solve the above problems. Disclosure of utility model The utility model aims to solve the problems and provide the drug delivery device for the gold microneedle, which solves the problem that the stop lever is easy to separate from the hole of the stop lever in the use process of the microneedle, so that the stability of the microneedle in the use process is improved.
