Problems solved by technology

But all kinds of microneedles only pierce the stratum corneum of the skin to provide penetration channels for the nutrient solution, so before implementing the traditional microneedle, it is necessary to provide the skin with nutrient solution through traditional methods, such as pinching and pressing with a dropper The bottle will drop the nutrient solution to the desired skin position, and then use microneedles to help the nutrient solution penetrate into the skin for easy absorption, which is inconvenient to use. If the dropper that provides the nutrient solution is not sterilized, it will bring safety hazards to users

Embodiment 1

[0044] Such as figure 1 , figure 2 As shown, the embodiment of the present invention provides an injectable microneedle chip set, including a connector 1 and a microneedle chip 2, the microneedle chip 2 includes a substrate 20 and a microneedle array disposed on the substrate 20, The microneedle array includes a number of microneedles 21 uniformly distributed on a substrate 20, and the substrate 20 is provided with a plurality of microholes 22 interspersed in the microneedle array. The substrate 20 is preferably a bioceramic sheet or a silicon sheet.

[0045] The connector 1 includes a tube section 10 and a cavity section 11, the end of the cavity section 11 is provided with a support surface for clamping or bonding the microneedle wafer 2, and the substrate 20 is clamped or bonded and fixed, The lumen of the tube section 10 , the lumen of the cavity section 11 and the micropores 22 are in communication.

[0046] The pipe section 10 of the connecting piece 1 is screwed or ...

Embodiment 2

[0051] Such as image 3 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that: the back side of the substrate 20 is provided with a first pedestal 24, and the first pedestal 24 corresponds to the microhole 22. A hollow needle is provided at the position, and the hollow needle protrudes forward from the microhole 22 to the front side of the substrate 20 .

Embodiment 3

[0053] Such as Figure 4 As shown, the structure of the present embodiment is basically the same as that of the second embodiment, the difference is that: between the substrate 20 and the first base 21, there is a second The base 25, the second base 25 is provided with a second microhole corresponding to the position of the microhole 22, and the hollow needle protrudes to the front side of the substrate 20 after passing through the second microhole and the microhole in turn .

Abstract

The invention provides an injectable micro-needle wafer suite. The wafer suite comprises a connecting part and a micro-needle wafer. The micro-needle wafer comprises substrates and micro-needle arraysarranged on the substrates, the micro-needle arrays comprise multiple micro-needles evenly distributed on the substrates, one or more micro-holes which penetrate through and are inserted into the corresponding micro-needle arrays are formed in each substrate, can be in a conical protruding needle point shape or in a hole shape, the connecting part comprises a pipe section and a cavity section, agroove is formed in the end of the cavity section, the micro-needle wafer is clamped into the groove, the substrates are clamped into the groove, and an inner cavity of the pipe section, an inner cavity of the cavity section and the micro-holes are communicated. Liquid is injected while the injectable micro-needle wafer suite opens a skin cuticula, and therefore using is safe and convenient; compared with a micro-needle without micro-holes sold in the current market, a transdermal absorption effect is more excellent; the injectable micro-needle wafer suite can be used for subcutaneous importing of medicine and a nutrient solution, and is convenient to use in cooperation with an injection needle or other beautifying instruments.

Description

technical field [0001] The invention relates to the field of medical cosmetic devices, in particular to an injectable microneedle wafer set. Background technique [0002] Microneedle therapy, also known as microneedle mesoderm beauty therapy, is a nursing method that directly introduces skin care active ingredients or nutrients into the subcutaneous tissue to exert beauty effects. Microneedle is the use of small needles to penetrate the stratum corneum, creating many ultra-micro channels to help the introduction of nutrients. Microneedle therapy uses many tiny needles to stimulate the skin and pierce the stratum corneum, so that the active ingredients of the nutrient solution can penetrate into the skin effectively through ultra-micro channels, and finally achieve the reduction of wrinkles, treatment of scars and stretch marks, skin whitening and lightening. Spots, improve eye wrinkles, dark circles, tighten and enhance facial skin tissue and other effects. [0003] The sc...
