[0031] See attached Figure 1-3 The utility model provides a microneedle patch 1000 introduction device, comprising:

[0032] The shell 100 has a receiving cavity for accommodating the mechanism elements, and an opening is provided at one end of the shell 100; the user can hold and use the shell 100.

[0033] The introduction mechanism 200 is fixed in the shell 100 and has a movable end, which can move towards or away from the opening of the shell 100; when the introduction device is used, the movement of the introduction mechanism 200 enables the movable end to move towards or away from the human skin.

[0034] The adsorption mechanism 300 includes a first driving member, a magnetic member 320 and an abutting member 330 having a accommodating cavity. The magnetic member 320 is arranged in the accommodating cavity of the abutting member 330. The first driving member is transmission-connected to the magnetic member 320. The first driving member can drive the magnetic member 320 to reciprocate in the accommodating cavity. The microneedle patch 1000 with a magnetic attraction function, such as a magnet or a patch, can achieve an adsorption and fixing effect with the magnetic member 320.

[0035] The side of the abutment member 330 away from the moving end is the adsorption end for adsorbing and installing the microneedle patch 1000, and the magnetic suction member 320 can be close to or away from the adsorption end in the accommodating cavity; when the magnetic suction member 320 is close to the adsorption end, the adsorption end has the magnetic adsorption force of the magnetic suction member 320, thereby achieving the adsorption effect on the microneedle patch 1000; when the magnetic suction member 320 is away from the adsorption end, the influence of the magnetic suction member 320 on the adsorption end can be reduced, so that the microneedle patch 1000 and the adsorption end are desorbed, thereby achieving the separation of the microneedle patch 1000 from the adsorption end.

[0036] The abutment member 330 is fixedly installed on one side of the mobile end, and the mobile end can drive the abutment member 330 to abut against or move away from the skin. The abutment member 330 drives the mobile end, thereby driving the adsorption member to move closer to or away from the skin.

[0037] The first driving member drives the magnetic member to move back and forth, and controls the distance between the magnetic member and the adsorption end, so that the adsorption end of the abutting member 330 used to abut the skin can realize the strength control of its magnetism through the drive of the first driving member, thereby realizing the adsorption and detachment control of the microneedle patch 1000 with magnetic adsorption material. When the introduction device is in use, the moving end of the introduction mechanism 200 moves toward or away from the shell 100, driving the abutment component 330 with the microneedle patch 1000 adsorbed thereon to abut against the human skin, so that the microneedle patch 1000 is inserted into the skin and the abutment component 330 is moved away from the human skin. In combination with the magnetic strength control of the adsorption end, the abutment component 330 can adsorb the microneedle patch 1000 and drive the microneedle patch 1000 toward the human skin and apply it to the skin. The adsorption end and the microneedle patch 1000 are magnetically separated, and the abutment component 330 then moves the moving end toward the shell 100 to separate the adsorption end from the microneedle patch 1000, completing the entire process of automatically introducing the microneedle patch 1000 into the skin and separating the microneedle patch from the adsorption end. The microneedle patch 1000 introduction device can achieve stable introduction of the microneedle patch 100, avoiding the influence of different strengths and uneven force application when traditional users apply it manually.

[0038] The method of using the microneedle patch 1000 introduction device is as follows: before use, the moving end of the introduction mechanism 200 retracts and moves toward the accommodating cavity away from the opening end of the shell 100, driving the abutment member 330 to retract into the opening of the shell 100, and at the same time, the first driving member drives the magnetic suction member 320 to approach the adsorption end of the abutment member 330, so that the magnetic suction member 320 is completely close to the adsorption end. At this time, the magnetic suction member 320 is closest to the adsorption end of the abutment member 330, so that the adsorption end of the abutment member 330 has a magnetic attraction, which can achieve the adsorption of the microneedle patch 1000. This state is the "initial" state. The microneedle patch 1000 with magnetic adsorption function is placed on the adsorption end, and is fixed to the adsorption end by the magnetic adsorption of the magnetic suction member 320, and the opening end of the shell 100 is facing the human skin. The introduction mechanism 200 moves toward the opening of the shell 100, and the moving end drives the abutment member 330 to extend outward, so that the adsorption end with the microneedle patch 1000 adsorbed thereon approaches the skin and contacts the skin, and the microneedle patch 1000 at the adsorption end is driven to be pressed toward the human skin by the outward movement of the moving end, so that the microneedle patch 1000 can completely penetrate the skin; while the microneedle patch 1000 is kept pressed, the first driving member drives the magnetic suction member 320 away from the adsorption end, reducing the magnetic attraction between the magnetic suction member 320 and the microneedle patch 1000, and the attraction force on the magnetic microneedle patch 1000 gradually weakens. After pressing, the shell 100 is removed. At this time, the magnetic adsorption force between the adsorption end and the microneedle patch 1000 is much smaller than the adhesion force between the microneedle patch 1000 and the skin, and the microneedle patch 1000 introduction device can be directly removed. At this time, the microneedle patch 1000 is separated from the adsorption end, and the introduction mechanism 200 drives the abutment component 330 to retract into the opening of the shell 100, and the magnetic component extends. The distance between the magnetic component and the abutment component 330 is the shortest, and the "initial" state is restored.

[0039] Furthermore, the introduction mechanism 200 includes a second driving member 210 and a connecting member 220. The second driving member 210 is transmission-connected to the connecting member 220. The second driving member 210 can drive the connecting mechanism to move back and forth. The abutment member 330 is fixedly connected to the connecting member 220. Through the reciprocating movement of the connecting member 220, the abutment member 330 is driven to abut against the skin or away from the skin.

[0040] The first driving member and the magnetic member 320 are connected by a threaded screw, and the second driving member 210 and the connecting member 220 are connected by a threaded screw. The reciprocating movement of the magnetic member 320 in the abutting member 330 is achieved through the threaded screw connection.

[0041] Specifically, the first driving member and the second driving member 210 each include a driving motor 400, a transmission gear 500 and a screw rod 600, the driving motor 400 is meshedly connected with the input end of the corresponding transmission gear 500, the output end of the transmission gear 500 is meshedly connected with one end of the corresponding screw rod 600, the screw rod 600 of the first driving member is threadedly connected with the magnetic member 320, and the screw rod 600 of the second driving member 210 is threadedly connected with the connecting member 220; the first driving member and the second driving member 210 are respectively rotated by their respective driving motors 400, driving the corresponding screw rod 600 to realize the rotation of the screw rod 600; wherein, the magnetic member 320 and the connecting member 220 are both provided with threaded holes, which are threadedly matched with the corresponding screw rod 600 to realize the axial reciprocating transmission of the magnetic member 320 and the connecting member 220, thereby realizing the magnetic adsorption control of the microneedle patch 1000 and the approach and distance from the skin.

[0042] In this embodiment, the transmission gear 500 is a multi-stage gear, and the driving motor 400 provides a high speed, which is converted by the gear motor of the multi-stage gear to achieve the speed adjustment and control output, which can meet the power and speed allocation for pressing the skin.

[0043] Furthermore, a flexible material in the form of an annular protrusion 700 is provided at the edge of the opening. Through the provision of the flexible material, the opening can fit better when in contact with the skin, thereby improving the physical feel when used; and through the structural provision of the annular protrusion 700, the annular protrusion 700 is abutted against the fitting area of ​​the microneedle patch 1000. The abutment of the annular protrusion 700 enables the skin introduction area corresponding to the opening to be pressed down by the flexible material of the annular protrusion 700 when pressed hard, thereby achieving the skin flattening effect in the opening, thereby making the skin fitting area of ​​the microneedle patch 1000 smoother, thereby improving the fitting effect of the patch; wherein, the flexible material can be made of skin-friendly materials such as latex rubber.

[0044] Specifically, the flexible material annular protrusion 700 is hollow, so that the flexible material annular protrusion 700 can fit the uneven skin, and is easy to deform to adapt to the skin in different positions, so as to better achieve the effect of flattening and abutting the skin.

[0045] Among them, a plurality of first pressure sensors 800 are arranged on the surrounding side of the flexible material. The first pressure sensors 800 are used to detect the pressure when the annular protrusion 700 of the flexible material is in contact with the human skin. The first pressure sensor 800 is electrically connected to the second driving member 210. When the flexible material is in contact with the human skin, the first pressure sensor 800 detects the contact pressure of the flexible material. The first pressure sensor 800 is provided with a set value. When the contact pressure of the first pressure sensor 800 is higher than the set value, it ensures that the shell 100 is stably in contact with the skin. At this time, the second driving member 210 drives the contact member 330 to extend, so that the microneedle patch 1000 is in contact with the skin.

[0046] Furthermore, the abutment member 330 is provided with a second pressure sensor 900, which is used to detect the abutment pressure of the abutment member 330 when it abuts against the force, that is, the abutment pressure when the microneedle patch 1000 is driven to penetrate the human skin. The second pressure sensor 900 is electrically connected to the first driving member and the second driving member 210. The second pressure sensor 900 is provided with a set value. When the abutment pressure of the second pressure sensor 900 is higher than the set value, it is ensured that the abutment member 330 is stably abutted and pressed against the skin. When the abutment member 330 drives the microneedle patch 1000 to abut and penetrate the human skin, the abutment pressure detected by the second pressure sensor 900 is higher than the set value, and the second driving member 210 stops running, so that the abutment member 330 pauses moving, so that the microneedle patch 1000 remains pressed against the skin, and the first driving member drives the magnetic member to move to the side away from the abutment end, so that there is no adsorption force between the microneedle patch 1000 and the abutment member 330, which facilitates the separation of the microneedle patch 1000 from the abutment member 330 on the skin.

[0047] In this embodiment, the abutment member 330 includes an abutment portion 331 and a positioning frame 332. The abutment portion 331 is formed with a groove body for accommodating the magnetic suction component 320. The positioning frame 332 is sleeved on the outer side of the first driving member. The connecting member 220 is connected to the abutment portion 331 through the positioning frame 332. The two sides of the positioning frame 332 are respectively connected to the connecting member 220 and the abutment portion 331; the second pressure sensor 900 is arranged on the abutment portion 331; the positioning frame 332 is used to realize the positioning support of the first driving member, thereby realizing the independent directional movement of the first driving member and the second driving member 210, so that when the abutment member 330 moves, the magnetic suction component 320 reciprocates in the groove body, thereby realizing the control of the adsorption force between the abutment portion 331 and the microneedle patch 1000.

[0048] Furthermore, it also includes a fixed bracket 110, and the introduction mechanism 200 is fixed on the fixed bracket 110, and the fixed bracket 110 is fixed to the inner wall of the shell 100. The fixed bracket 110 is used to achieve fixed positioning of the introduction mechanism 200 in the shell 100, thereby improving the tightness of the connection between the introduction mechanism 200 and the shell 100 and ensuring the working stability of the introduction mechanism 200 when pushing the abutment member 330.

[0049] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
