Description

Technical Field

[0001] The utility model relates to the technical field of transdermal microneedles, and particularly relates to a microneedle device for delivering photons. Background Art

[0002] Photo rejuvenation is a technology that uses light energy of a specific wavelength to treat and beautify the skin. Its principle is to select an appropriate wavelength and light intensity, transfer the light energy to the deep layer of the skin, stimulate the regeneration and repair of collagen in the skin and the true surface layer, promote metabolism, improve skin relaxation, balance sebum secretion, reduce pigment deposition, brighten the skin tone, so as to achieve the effects of wrinkle removal, skin rejuvenation, and whitening. Photo rejuvenation can improve skin problems such as skin relaxation, enlarged pores, skin spots, and acne scars, making the skin more delicate, smooth, and uniform. Blue light: approximately between 410 - 490 nanometers, commonly used for sterilization and controlling sebum secretion. Red light: usually between 620 nanometers and 700 nanometers, having the effect of promoting collagen and skin regeneration. Near-infrared light, approximately between 700 nanometers and 1200 nanometers, can deepen the photothermal effect, promote blood circulation, and skin repair. Lights of different wavelengths also have different functions and effects in photo rejuvenation. Physicians will select an appropriate wavelength for treatment according to the skin problems and needs of patients. However, in the existing photo rejuvenation technology, photons cannot directly reach the dermis layer, and the photon transfer efficiency is low, affecting the skin treatment and beautification effects.

[0027] Referring to Figure 1-3 , an embodiment of the present utility model provides a microneedle device for delivering photons, including: a microneedle body 1, a base layer 2, a translucent layer 6, and a light-impermeable adhesive layer 4. The light-impermeable adhesive layer 4, the translucent layer 6, and the base layer 2 are sequentially arranged from bottom to top. A photon channel is formed on the microneedle body 1. The microneedle body 1 is disposed on the base layer 2. A light channel 5 communicating with the photon channel of the microneedle body 1 is disposed on the base layer 2. A light-shielding plate 3 is disposed around the translucent layer 6. A hollow hole 7 communicating with the light channel is disposed on the light-impermeable adhesive layer 4.

[0028] In the above technical scheme, the back side of the opaque adhesive layer 4 is connected to a photon rejuvenation device, by providing a microneedle body 1 with a photon channel on the base layer 2, and providing an optical channel 5 connected to the photon channel of the microneedle body 1 on the base layer 2; during skin treatment, the microneedle body 1 can carry or be filled with therapeutic drugs to deliver drugs to the epidermis and dermis of the skin. After the drug is absorbed by the skin, the photon radiation energy can directly reach the dermis with the help of the matching structure of the optical channel 5 and the photon channel, thereby improving the photon transmission efficiency and making the skin treatment and beauty effects more excellent.

[0029] In some embodiments, a light shield 8 is disposed on the side of the light-proof adhesive layer 4 away from the light-transmitting layer. Specifically, the light shield 8 can be an annular structure, such as a square annular structure, a circular annular structure or other special-shaped annular structures, etc. The hollow hole 7 is located in the light shield 8. The light shield can effectively prevent light leakage.

The microneedle body 1 can be used alone or in combination with a drug. When used in combination with a drug, a drug needle 12 can be provided at the top first photon channel 9 of the needle body 101, wherein the drug needle 12 is a conical structure composed of drugs, which can be formed by freeze-drying, and the hollow inner cavity of the shell of the microneedle body 1 can be used to carry and fill drugs. When the drug is absorbed by the skin, the first photon channel 9 is turned on, and the photon radiation energy directly reaches the dermis with the help of the first photon channel 9, thereby improving the photon transmission efficiency.

[0034] In some embodiments, the microneedle body 1 is made of amorphous alloy material. This structural design makes the biocompatibility of the microneedle body 1 more excellent; specifically, the microneedle body 1 is a titanium-based amorphous alloy material, such as Ti 60-x -Cu 19 -Zr 11-x -Fe 6+x -Sn4-Si x (0.5 ≤ X ≤ 13).
