Description

Microneedle device for private nursing of pudendum

Technical Field

The utility model relates to the technical field of female nursing, in particular to a microneedle device for private nursing of private parts.

Background

The private nursing refers to nursing the private parts and the reproductive system of females, so that the reproductive system of females can be kept or restored to a healthy and young state.

The microneedle operation is to form a plurality of micro-pipes on the skin by utilizing a micro needle head, stimulate the regeneration of collagen in the skin, effectively promote the metabolism of the skin and keep the elasticity of the skin, thereby achieving the effects of tightening the skin and beautifying and moisturizing the skin. At the same time, the micro-needles penetrate through the stratum corneum of the skin to reach the epidermis without touching the dermis, and the active ingredients smeared on the skin can penetrate through the subcutaneous layers of the small channels to enhance the penetration of the active ingredients.

The vagina is a muscular canal consisting of mucous membrane, muscular layer and adventitia, rich in extensibility, connecting the uterus and external genitalia. Because of the 'tubular' structure of the vagina, such as applying microneedle operation to the vagina by directly utilizing the current microneedle roller, on one hand, the microneedle roller is difficult to enter the vagina, and on the other hand, the vagina is easy to be damaged.

Referring to fig. 1 to 3, a microneedle device for private care of the pudendum according to an embodiment of the present utility model includes a cylinder 1, a head 2, a plurality of microneedle groups, a driving shaft 3, and a cover 4. The circumferential wall surface of the cylinder 1 is provided with a plurality of through hole groups which are distributed parallel to the axis of the cylinder 1, the through hole groups are composed of a plurality of through holes, and each through hole is arranged towards the axis of the cylinder 1. The cylinder 1 is preferably made of medical stainless steel materials. The number of the through hole groups, the number of the through holes in each through hole group can be set according to the actual condition of the operation of the microneedle 5, and this embodiment is not limited thereto.

The seal head 2 is installed at the opening of the first end of the cylinder 1, and the seal head 2 is installed at the opening of the upper end of the cylinder 1 corresponding to the view angle of fig. 1. The seal head 2 and the cylinder body 1 can be integrally formed, can be welded or connected, or can be detachably connected, preferably detachably connected. The seal head 2 seals the first end opening to prevent foreign objects from entering the cylinder 1 through the first end opening, and meanwhile, the seal head 2 can also reduce the stimulation to the vagina in the process of entering the vagina by the microneedle 5 device, specifically, the seal head 2 can be an elliptical seal head 2, a spherical seal head 2 or other seal heads 2 with outer surfaces in a convex shape. Likewise, the seal head 2 is preferably made of medical stainless steel materials.

The microneedle group consists of a plurality of microneedles which can be simultaneously clung to the inner walls of the through holes of the corresponding through hole groups to move, and the tail parts of the microneedles 5 belonging to the same microneedle group are fixed on the corresponding needle seat 6. Preferably, the needle holder 6 is elongated and forms a curved surface matching the inner wall of the barrel 1.

The driving shaft 3 is supported by two bearings 7 disposed at both ends of the inner wall of the cylinder 1 to ensure smooth rotation of the driving shaft 3. The driving shaft 3 is connected with each needle seat 6 through a connecting rod 8, and the driving shaft 3, the connecting rod 8, the cylinder body 1 and the micro needle form a crank slide block mechanism, so that the micro needle 5 can be driven to extend out of the through hole and retract into the through hole when the driving shaft 3 rotates. For example, when the driving shaft 3 is rotated counterclockwise by an angle a, the micro needle 5 protrudes out of the through hole, and then when the driving shaft 3 is rotated clockwise by an angle b, the micro needle 5 is retracted into the through hole. Therefore, in the process of extending the microneedle 5 device to the preset vaginal position, the microneedle 5 is retracted into the through hole, after reaching the preset vaginal position, the driving shaft 3 rotates and drives the microneedle 5 to extend out of the through hole, the microneedle 5 is utilized to promote the vaginal wall to form a plurality of micro-fine pipelines, when the microneedle 5 device needs to be moved to the next preset position or taken out, the driving shaft 3 is rotated again to drive the microneedle 5 to retract into the through hole, so that the microneedle 5 device can easily enter and exit the vagina and cannot damage the vagina when the microneedle 5 device is utilized to apply the microneedle 5 operation to the vagina.

In one embodiment, as shown in fig. 4 and 5, an annular connecting disc 9 is sleeved and fixed on the driving shaft 3, and the driving shaft 3 is connected with each connecting rod 8 through the annular connecting disc 9. The annular connecting disc 9 is additionally arranged, so that the assembly difficulty of the microneedle 5 device can be reduced. The annular connecting disc 9, the connecting rod 8, the cylinder body 1 and the micro needle form a crank sliding block mechanism, so that the micro needle 5 can be driven to extend out of the through hole and retract into the through hole when the driving shaft 3 rotates.

Returning to fig. 1 and 3, the cover 4 is mounted at the second end opening of the cylinder 1, and corresponding to the view angle of fig. 1, the cover 4 is mounted at the lower end opening of the cylinder 1, and a hole for the driving shaft 3 to extend is formed. Preferably, the cover 4 is detachably connected to the cylinder 1.

The first handle 10 and the second handle 11 are additionally arranged, so that the microneedle 5 device can be conveniently controlled. Specifically, the first handle 10 is fixedly connected with one end of the cover 4 opposite to the cylinder 1, and a straight hole for extending the driving shaft 3 is formed. The second handle 11 is rotatably connected with one end of the first handle 10 far away from the cover body 4, and one end of the driving shaft 3 extending out of the first handle 10 is fixedly connected with the second handle 11. When the microneedle 5 device is used, one hand can hold the first handle 10, the other hand holds the second handle 11 and rotates, and the driving shaft 3 can be driven to rotate, so that the microneedle 5 is driven to extend out of the through hole and retract into the through hole.

Preferably, the outer peripheral wall of the second handle 11 is formed with a blocking portion 12 protruding upward, and the outer peripheral wall of the first handle 10 is formed with a first limiting portion 13 and a second limiting portion 14 extending to both ends of the movement track of the blocking portion 12. When the blocking part 12 abuts against the first limiting part 13, the micro needle 5 is in a state of extending out of the through hole, and when the blocking part 12 abuts against the second limiting part 14, the micro needle 5 is in a state of retracting into the through hole. So that it can be judged whether the microneedle 5 is in a state of extending out of the through-hole or in a state of retracting into the through-hole according to the position of the stopper 12.

In another embodiment, as shown in fig. 6, the microneedle 5 device further comprises a handle 15, a drive mechanism, a control circuit 16, and a power source 17.

For example, the driving mechanism may be composed of a motor 18 and a speed reducer 19, and the motor 18 drives the driving shaft 3 to rotate through the speed reducer 19 when working.

The control circuit 16 is disposed in the accommodating chamber and electrically connected to the driving mechanism for controlling the driving mechanism to operate according to a signal transmitted from a button disposed on the handle 15. If the first button 20 is pressed, a signal for extending the microneedle 5 is transmitted to the control circuit 16, and if the second button 21 is pressed, a signal for retracting the microneedle 5 is transmitted to the control circuit 16. Of course, the number of buttons and the signals transmitted may be set according to practical situations, which is not limited in this embodiment. Preferably, the control circuit 16 is a single-chip microcomputer.
