Description

Technical Field

[0001] The present invention relates to the field of transdermal release devices for medical media, in particular to a handheld nano-chip massage introduction beauty instrument. Background Art

[0002] Skin care products or medications applied to the skin's surface rarely penetrate the tough stratum corneum and reach the dermis, resulting in less than 0.3% of the nutrients actually being absorbed. Nano-microneedle therapy is a novel physical penetration enhancement method. Through the reciprocating motion of pre-placed nano-microneedles or nano-chips and their corresponding components, piercing the stratum corneum creates tiny channels for nutrients to enter the dermis without damaging the dermis or underlying nerves, and without causing pain, discomfort, or bleeding. Nano-microneedle technology has promising applications in combating skin dehydration, aging, pigmentation, treating dry skin, acne, and reducing cellulite. Applications have already begun in Europe, America, Japan, and South Korea.

[0003] Existing nano-microneedles are mostly conical in shape, with nanometer-scale needle tips. These create tiny nano-scale channels in the skin's stratum corneum, allowing drugs or nutrients to penetrate the stratum corneum barrier and directly reach the dermis. However, due to the small size of the incision channel, drug and nutrient absorption is limited. Furthermore, existing nano-microneedle delivery devices are mostly single-tip nano-microneedles with a single function and limited penetration efficiency.

[0004] Patent application number CN201510149559.5 discloses a channel-type nano-beauty device and its use method. The device comprises a syringe, a main frame, a top cover, a nano-chip, and an end cap. The syringe is filled with liquid, the main frame is mounted at the end of the syringe, the top cover wraps around the top of the main frame, and the nano-chip is placed in the center of the top of the top cover. A channel is provided around the top circumference of the top cover for liquid outflow. After the liquid flows out through the channel, the beauty device drives the nano-chip to vibrate. However, this beauty device still requires an external motor, is uncompact, and has limited functionality. Summary of the Invention

[0005] The purpose of the present invention is to disclose a handheld nano-chip massage introduction beauty instrument with a compact structure, capable of expanding the percutaneous entry channel and storage of media and promoting skin absorption.

[0008] The Y-shaped or multi-tooth fork-shaped shaft is located in the inner cavity of the beauty instrument shell, and the Y-shaped end or the multi-tooth fork-shaped end of the Y-shaped or multi-tooth fork-shaped shaft passes through the beauty instrument shell and is connected to the introduction head and the massage head; the other end of the Y-shaped or multi-tooth fork-shaped shaft is connected to the transmission device, one end of the eccentric device is placed in the inner cavity of the transmission device, and the other end of the eccentric device is connected to the waveform vibration motor; the waveform vibration motor is connected to the CNC board, and the CNC board is connected to the power supply.

[0009] Furthermore, the introduction head includes a nano-microneedle array and an introduction head injection molding component;

[0010] The nano-microneedle array includes a support body and one or more nano-microneedles; the nano-microneedles are fixed on the support body, the support body is fixed on the introduction head injection molding component, and the introduction head injection molding component is connected to a Y-shaped or multi-tooth fork-shaped shaft.

[0011] Furthermore, the nano-microneedle includes a needle tip, one or more boss structures, and a microneedle body; the needle tip is located above the one or more boss structures, the microneedle body is located below the one or more boss structures, and the microneedle body is connected to the boss structure through a straight line or curve transition.

[0012] Furthermore, the nano-microneedle is a hollow or solid structure.

[0013] Furthermore, when the nano-microneedle is a hollow structure, a through hole from the support to the needle tip or a non-through hole from the support upward is opened inside the nano-microneedle.

[0014] Furthermore, the surfaces of the support and the microneedle body are coated with a silicon nitride film or a metal titanium film.

[0015] Furthermore, the boss structure includes but is not limited to a spherical, elliptical or polygonal pyramid structure.

[0016] Furthermore, the massage head includes a spherical or sheet-shaped massage head end with a boss structure array and a massage head injection molding component; the spherical or sheet-shaped massage head end with a boss structure array is connected to the massage head injection molding component, and the massage head injection molding component is connected to a Y-shaped or multi-tooth fork-shaped shaft.

[0017] Furthermore, the power source is an external power source or a battery.

[0018] The beneficial effects of the present invention are:

[0019] The present invention designs a nano-microneedle with a boss structure, which can penetrate the stratum corneum of the skin without touching the dermis and subcutaneous nervous system, creating a channel for the percutaneous entry of biomedical media and other media without causing skin pain and irritation. At the same time, the presence of the boss structure can effectively expand the percutaneous introduction pathway and expand the storage space of biomedical macromolecular media in the skin; the waveform vibration of the massage head of the present invention can accelerate the rate at which nutrients pass through the stratum corneum of the skin, thereby accelerating the introduction and absorption of biomedical media and other media into the skin.
