Description
Technical Field
[0001] The utility model belongs to the field of medical devices, and particularly relates to a stamp micro needle with pump type precise introduction. Background Art
[0002] There are two process manufacturing methods for micro needle sheets: one is the etching method, and the produced needle sheet is a conical sheet needle, with 60 needles per sheet (usually 540 needles), separated by clip sheets in the middle, one clip sheet for one needle sheet, and finally fixed at both ends to form a tube wheel head. The other is to use solid round needles, install them on one sheet after another, and then add each sheet to the roller at the reserved position to form a roller with micro needles (usually 192 needles).
[0003] Currently, the popular micro needles on the market are mostly handle combination roller devices, with the rolling needles placed inside the rollers. For the existing rolling needles, the essence needs to be applied to the treatment area in advance, and then the rolling needle therapy is implemented. Among them, the rolling needles only play a role in stimulating the skin and creating micro holes on the skin to allow the skin to naturally absorb the surface essence. It cannot introduce the micro needles into the skin automatically while implementing the rolling needle therapy. In addition, applying the essence to the skin in advance will waste a lot of essence on the skin surface, and it cannot be introduced into the skin drop by drop for the skin to absorb, failing to achieve the effect of precise targeted treatment.
[0004] For the needles on the market, whether they are sheet needles or solid needles, the diameter of the needle filaments is 0.3 mm, and then they are processed by a sharpening process, but the process is still rough, the needle tips are not sharp enough, the strength is insufficient, the edges are uneven, resulting in strong pain, large trauma, long recovery period during use, and prone to bleeding or even oozing blood.

[0020] The utility model discloses a stamp microneedle with pump-type precision introduction, which can better introduce liquid into the skin through a movable guide device, and can improve the effect of precise targeted treatment. The movable guide device of the utility model is equipped with an elastic telescopic part. When the new needle thread pierces the skin, the elastic telescopic part is compressed to generate a certain resistance and rebound force, and the rebound force pierces the needle thread into the skin, which is more labor-saving; when released, the elastic telescopic part will detach from the skin and stretch, and the operation is more humane. Among them, because the movable guide device is equipped with an elastic telescopic part, when compressed, the bottom cover of the movable guide device and the chamber of the buckle device will form a pump effect, thereby pushing the liquid in the chamber along the "guide component → new needle thread" into the skin. This design can better introduce the liquid into the skin, solving the shortcomings of applying the essence on the skin and then applying the rolling needle therapy. Among them, the movable guide device includes a new needle thread, which can solve the problem of trauma caused by the needle tip of the previous needle thread being not sharp enough and the uneven edge. The other end of the buckle device of the utility model can be externally connected to a bottle (such as an ampoule), and different medicines or essences can be contained in the bottle. When the new needle thread penetrates into the skin, the medicine or essence can be introduced into the skin instead of staying on the surface for absorption by the skin. Moreover, the utility model has different degrees of introduction as the needle length penetrates into the skin to different depths, thereby achieving the effect of precise targeted treatment.
