Description

Technical Field

[0001] The utility model belongs to the technical field of percutaneous delivery devices, and particularly relates to a penetration enhancing device. Background Art

[0002] A penetration enhancer is a type of instrument used in conjunction with a micro device. The penetration enhancer has a built-in driving mechanism that can drive the microneedles to move, thereby assisting the microneedles to open the skin barrier and improving the effect of drug transdermal absorption. A micro device is a new type of transdermal drug delivery device. The surface of the micro device is integrated with microneedle arrays, micro blades, micro protrusions and other microstructures. The size of these microstructures can reach the micron level or even the nano level. They can open the skin barrier and promote the absorption of drugs and nutrients. They are painless and non-invasive during use and are widely used in the fields of medical treatment and beauty skin care. Patent CN204017141U discloses a penetration enhancer, whose driving mechanism can output reciprocating linear motion, drive the microneedles to perform reciprocating linear motion, and use the microneedles to open micro channels in the stratum corneum of the skin. Drugs can pass through the stratum corneum of the skin through these micro channels and reach the deep tissues of the skin to exert their effects.

[0003] However, the thickness of the stratum corneum of different people varies. Age, gender, race and even health status will affect the skin condition. At the same time, when using microneedles, users expect the microneedles to reach different depths in the skin in order to obtain different therapeutic effects. For this reason, microneedles of various lengths are required, resulting in a large number of microneedle height specifications. Consumers may not be able to make an accurate choice, resulting in less than expected results or even negative effects. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0024] like Figure 1 and 2 As shown, a penetration enhancer with adjustable action distance includes a housing 1, a first mechanism and a second mechanism, wherein the first mechanism is provided with a driving rod 21, the driving rod 21 is used to connect with a micro device, the second mechanism includes a power element 31, the power element 31 drives a first rotating member 32 to rotate, a first transmission mechanism is also provided between the first rotating member 32 and the driving rod 21, the first transmission mechanism converts the rotation of the first rotating member 32 into a reciprocating linear motion of the driving rod 21, and also includes an adjustment mechanism, the adjustment mechanism adjusts the position of the reciprocating linear motion of the driving rod 21 by adjusting the position of the first rotating member 32; the first mechanism includes a reset mechanism. The front end of the housing 1 abuts against the skin, and when the driving rod 21 is connected to the micro device, the micro device can act on the skin at the front end of the housing 1 during the reciprocating motion of the driving rod 21. When the front end of the shell 1 abuts against the skin, the skin will be slightly deformed and bulge into the shell 1 to form a bulge shape. When the microdevice reciprocates with the driving rod 21, the position range of the microdevice movement will affect the depth of the microdevice acting on the skin. Therefore, by adjusting the position of the reciprocating linear motion of the driving rod 21, the depth of the microdevice acting on the skin can be adjusted.

[0025] The first mechanism also includes a first transmission member 22 having an inclined surface, the first transmission member 22 is fixedly connected to the driving rod 21, and the first rotating member 32 includes a protrusion 321, the protrusion 321 is eccentrically arranged with respect to the rotation axis of the first rotating member 32, and the protrusion 321 cooperates with the inclined surface of the first transmission member 22 to convert the rotation of the first rotating member 32 into the reciprocating linear motion of the driving rod 21. When the first rotating member 32 rotates, since the position of the protrusion 321 is eccentrically arranged with respect to the rotation axis of the first rotating member 32, the position of the protrusion 321 will change periodically, and the contact position of the protrusion 321 with the inclined surface of the first transmission member 22 will also change accordingly, thereby driving the first transmission member 22 and the driving rod 32 to perform reciprocating linear motion. The first rotating member 32, the protrusion 321 and the first transmission member 22 together constitute the first transmission mechanism.

[0026] The output shaft of the power element 31 is connected to the second rotating member 33, and the second rotating member 33 is connected to the first rotating member 32 through a second transmission mechanism. The power element 31 is preferably a motor. The second rotating member 33 is a gear, and the first rotating member 32 includes a gear and a gear sleeve 58. The gear sleeve 58 is provided with a first tooth portion that meshes with the first rotating member 32 for transmission, and the gear sleeve 58 is also provided with a second tooth portion that meshes with the second rotating member 33 for transmission. The gear sleeve 58 is connected to the bearing seat assembly 52. ​​The gear sleeve 58 and the bearing seat assembly 52 constitute a second transmission mechanism. The bearing seat assembly 52 is provided on the first sliding mechanism 51, and the sliding direction of the first sliding mechanism 51 is the same as the direction of the reciprocating linear motion of the driving rod 21. The bearing seat assembly 52 is connected to the tail rod 53, and the rear end of the tail rod 53 has an inclined surface. The adjustment mechanism 5 includes an adjustment rod 54, and the adjustment rod 54 is provided with an inclined surface that matches the inclined surface of the tail rod 53. The adjustment direction of the adjustment rod 54 is perpendicular to the sliding direction of the first sliding mechanism 51. The adjusting rod 54 is guided and limited by the second sliding mechanism 55. Figure 2 As shown, when the tail rod 54 moves up and down, due to the matching relationship between the inclined surface of the adjustment rod 54 and the inclined surface of the tail rod 53, the bearing seat assembly 52, the gear sleeve 58 and the first rotating member 32 will move left and right accordingly, so that the position of the first rotating member 32 can be adjusted. When the position of the first rotating member 32 changes, the position of the protrusion 321 also changes accordingly. Due to the matching relationship between the protrusion 321 and the inclined surface of the first transmission member 22, after the protrusion 321 changes, the position range of the reciprocating motion of the first transmission member 22 and the driving rod 32 also changes accordingly, so that the depth of the micro device acting on the skin can be adjusted. Embodiment 2

[0027] like Figure 3As shown, the second embodiment is basically the same as the first embodiment, and the main difference is that the second rotating member 33 is a gear, the first rotating member 32 includes a gear, the gear is an internal gear, and the first rotating member 32 is meshed with the second rotating member 33. The first rotating member 32 is directly connected to the bearing seat assembly 52. Embodiment 3

The position of the adjustment rod 54 is changed by rotating the adjustment knob 56, which is easier to control. Embodiment 4

[0029] like Figure 5 As shown, the fourth embodiment is basically the same as the first embodiment, and the main difference is that the adjustment mechanism includes an electronic control system, and the electronic control system controls the adjustment amount of the adjustment mechanism.
