Description

Technical Field

[0001] The present invention relates to the technical field of skin care, in particular to a skin care device and a use method thereof. Background Art

[0002] Skin itching is a common symptom of skin diseases. Itching is a pain stimulus transmitted to the brain through pain nerve fibers via the spinal cord. Humans instinctively scratch the skin to form weak pain stimulation to cover the discomfort caused by the itching. Patients often scratch with their bare hands without the help of any equipment. Firstly, scratching by the nails can easily cause skin damage that is invisible to the naked eye, and then repeated scratching can cause skin damage visible to the naked eye or even bleeding. Secondly, the bacteria in the nails enter the skin lesions through the scratching action, which can easily cause local irritation and infection, resulting in new itching problems.

[0003] Traditional scratching tools, such as some long-handled wooden or plastic scratching rakes, can also provide a certain degree of itching relief, but the scratching method is no different from using fingernails. Compared with scratching with fingernails, only the material and the shape of the end are changed. Repeated use will still cause skin damage. Summary of the invention

[0037] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0039] like Figure 1-Figure 9 As shown, in the first aspect, the embodiment of the present application provides a skin care device, including a thorn ball 1, the thorn ball 1 includes a sphere 11, a plurality of thorns 12 (whose heads are set to be blunt), the plurality of thorns 12 are evenly connected to the outer circumference of the sphere 11, and the thorns 12 are arranged along the radial direction of the sphere 11; Figure 7 , Figure 8 As shown, the gripping portion 2 has a hemispherical cavity 21 matching the thorn convex ball 1 (the inner diameter of the hemispherical cavity 21 matches the outer contour of the thorn convex ball 1, so that the thorn convex ball 1 can roll freely in the hemispherical cavity 21), and the lower end of the hemispherical cavity 21 has an opening 211 for the thorn convex ball 1 to enter the hemispherical cavity 21 from bottom to top (the thorn convex ball 1 can be put into the hemispherical cavity 21 or taken out from the hemispherical cavity 21 through the opening 211); and a restraining portion 3, which is detachably connected to the lower end of the gripping portion 2, and has a restraining cavity 31 running through it from top to bottom, and the restraining cavity 31 and the hemispherical cavity 21 constitute a accommodating cavity for accommodating the thorn convex ball 1, and the restraining cavity 31 is used to restrict the thorn convex ball 1 from rolling in the hemispherical cavity 21; as shown Fig. 9 As shown, the restraining cavity 31 has a first port 311 close to the gripping portion 2 and a second port 312 away from the gripping portion 2 , and a portion of the thorn ball 1 extends outward from the restraining cavity 31 from the second port 312 .

[0040] In the specific implementation of this embodiment, the user holds the grip portion 2 and places the part of the body of the thorn ball 1 extending outward from the second port 312 against the skin (itchy area), and then holds the grip portion 2 and drives the skin care device back and forth to move on the skin surface. Figure 5 As shown, during this process, the thorn ball 1 rolls in the hemispherical cavity 21 (the thorn ball 1 rolls with the inner wall of the hemispherical cavity 21 as a fulcrum, and under the action of the constraint cavity 31, the thorn ball 1 can roll in the hemispherical cavity 21 and will not slide out of the accommodating cavity), and at the same time, the thorn protrusions 12 on the leaked part of the thorn ball 1 abut against the itchy skin surface. During the movement of the skin care device on the skin surface, the relative position of the thorn protrusions 12 and the skin is fixed, and the skin will not be dragged, which is not easy to cause skin damage; and at the same time, there will be a plurality of blunt thorn protrusions 12 in contact with the skin surface, while achieving relieving itching (the thorn protrusions 12 mainly apply pressure perpendicular to the skin surface to the skin, which is conducive to relieving the itchy feeling generated in the deep skin area), increasing the contact area with the skin, dispersing the pressure applied by the user, and avoiding skin damage; at the same time, the thorn protrusions 12 are also functional modules for the thorn ball 1 to achieve rolling, providing a fulcrum for the thorn ball 1 to roll relative to the skin surface.

[0041] When the skin care device needs to be cleaned, the staff can remove the constraint part 3 from the grip part 2. At this time, the thorn ball 1 is no longer constrained by the constraint part 3, and the thorn ball 1 can be taken out from the hemispherical cavity 21 of the grip part 2. At this time, the grip part 2, the thorn ball 1, and the constraint part 3 are divided into three separate individuals, which can be cleaned, disinfected and replaced accordingly according to the wear conditions (for reuse); when it is necessary to assemble them together, the staff first puts the thorn ball 1 into the hemispherical cavity 21 from the opening 211 from bottom to top, and then connects the constraint part 3 to the lower end of the grip part 2. At this time, the constraint cavity 31 of the constraint part 3 and the hemispherical cavity 21 of the grip part 2 constitute a accommodating cavity, and the thorn ball 1 is confined in the hemispherical cavity 21 through the constraint cavity 31, thereby completing the assembly of the skin care device.

[0042] In some embodiments of the present application, Fig. 9 As shown, the constraint portion 3 includes a first cylindrical portion 32 and a second cylindrical portion 33 connected to the lower end of the first cylindrical portion 32 (the first cylindrical portion 32 and the second cylindrical portion 33 are integrally formed), and the cylindrical cavity of the first cylindrical portion 32 is connected to the cylindrical cavity of the second cylindrical portion 33 and constitutes a constraint cavity 31, as shown in FIG. Figure 5 As shown, the thorn convex ball 1 is accommodated in the accommodating cavity composed of the hemispherical cavity 21 and the restraining cavity 31, and under the action of the restraining cavity 31, the thorn convex ball 1 is confined in the hemispherical cavity 21; Figure 7As shown, the inner diameter of the second cylindrical portion 33 gradually decreases in the direction away from the first cylindrical portion 32, so as to form a second port 312 at one end of the second cylindrical portion 33 away from the first cylindrical portion 32, and the second port 312 is used to confine the thorn ball 1 in the accommodating cavity; Fig. 9 As shown, the first cylindrical portion 32 forms a first port 311 at one end away from the second port 312 .

[0043] like Figure 5 As shown, at this time, the thorn ball 1 is accommodated in the accommodating cavity composed of the hemispherical cavity 21 and the restraining cavity 31, and under the action of the restraining cavity 31, the thorn ball 1 is confined in the hemispherical cavity 21 and rolled in the hemispherical cavity 21, so as to achieve the effect of pressing the skin surface through the thorn protrusions 12 arranged on the thorn ball 1.

[0044] In some embodiments of the present application, Figure 2 , Figure 3 , Figure 8 As shown, an outer annular insertion groove 22 is provided on the outer periphery of the gripping portion 2 near one end of the restraining portion 3, which is plugged with the first port 311, so that the first port 311 is sleeved in the outer annular insertion groove 22, so that when the restraining portion 3 and the gripping portion 2 are assembled, the restraining cavity 31 has a flat inner wall, as shown in FIG. Fig. 9 As shown, an inner annular plug-in groove 34 may be provided on the inner wall of the first cylindrical portion 32, which is used to cooperate with the part of the body of the holding portion 2 inserted into the restraining portion 3, so that when the holding portion 2 and the restraining portion 3 are plugged and assembled, the inner wall of the restraining cavity 31 is ensured to be in a straight state (such as Figure 7 As shown: the inner wall of the hemispherical cavity 21 is flush with the inner wall of the partial restraining cavity 31 located below), which facilitates the rolling of the thorn ball 1.

[0045] In some embodiments of the present application, the restraining portion 3 in this solution is a flexible rubber part, which is convenient for plugging and matching with the holding portion 2.

[0046] In some embodiments of the present application, in order to facilitate the user to hold the skin care device, the upper end of the gripping portion 2 in this solution is configured as an arc-shaped surface so that the user has a better feel when holding the skin care device.

[0047] In some embodiments of the present application, the holding part 2 in this solution is a hard resin, which can be manufactured by 3D printing or mold infusion molding. The skin care device in this solution consists of a holding part 2 (made of resin material), a restraint part 3 (soft rubber), and a thorny ball 1 (plastic), which is light and easy to carry.

[0048] In a second aspect, the present application provides a method for using the skin care appliance in the above embodiment, comprising:

[0049] The thorn ball 1 is placed in the hemispherical cavity 21 , and the restraining portion 3 is connected to the lower end of the gripping portion 2 , so that the thorn ball 1 is confined in the hemispherical cavity 21 .

[0050] The user holds the grip 2 and places the prickly ball 1 against the skin surface, driving the skin care device to move back and forth on the skin surface, thereby achieving the effect of the multiple prickles 12 arranged on the surface of the prickly ball 1 acting on the itchy area of ​​the skin to relieve the itchy feeling generated in the deep skin area.

[0051] In some embodiments of the present application, the method for using the skin care appliance in the present solution further includes:

[0052] Apply skin pen ink or methylene blue to the surface of the pricking ball 1, and place the pricking ball 1 against the skin surface of the abnormal pain center area; hold the gripping part 2 and gradually move from the inside to the outside in a concentric circle from the abnormal pain center area; when the pricking ball 1 moves to the normal skin area, it stops moving and turns to the abnormal pain area to continue drawing. By using the skin care device in combination with skin pen ink or methylene blue, the patient's neuropathic pain area can be better marked.

[0053] The current means of examining abnormal pain sensation is often through questioning, which relies more on the patient's accurate verbal description, or requires the patient to point out the affected area with his or her fingers. However, this diagnostic method lacks accuracy and timeliness, and the patient may incorrectly express the location of the affected area due to insufficient verbal description ability. The finger-in-the-air method may also rely on the memory of past abnormal pain sensations rather than the real-time depiction of the abnormal pain area. Therefore, a tool that can continuously measure abnormal pain sensation is needed to achieve on-site detection and continuous marking without causing excessive pain to the patient. The use of the skin care device in this solution in combination with skin pen ink or methylene blue can better achieve the above requirements, that is, to achieve real-time and continuous detection on-site and make corresponding markings, solving the problem of lack of auxiliary devices that can continuously and evenly scan the abnormal pain site in clinical practice.

[0054] In some embodiments of the present application, the method for using the skin care appliance further includes:

[0055] The medicine is applied on the surface of the pricking convex ball 1, and the pricking convex ball 1 is made to abut against the skin surface that needs the medicine; the handheld skin care device is moved on the skin surface to evenly apply the medicine on the skin surface.

[0056] The working process of the present invention is: the user holds the grip 2 and places the exposed part of the pricking ball 1 against the surface of the affected skin, and then moves the skin care device back and forth on the skin surface, so that the pricking ball 1 rolls in the hemispherical cavity 21 with the skin surface as a fulcrum, and transmits the pressing force to the skin surface with the help of the pricking 12, thereby relieving the itching sensation generated in the deep skin area.

[0057] In summary, the embodiment of the present invention provides a skin care device and a method of use. In this solution, the thorn convex ball 1 is placed in the hemispherical cavity 21 of the gripping part 2 and combined with the restraining part 3, so that the thorn convex ball 1 can be restricted to roll in the hemispherical cavity 21; when the user uses it, the thorn convex ball 1 is pressed against the skin surface and the device is moved back and forth, so that the thorns 12 protruding from the surface of the sphere 11 are pressed against the skin surface, and multiple contact points are provided for the skin, while relieving itching, increasing the contact area, dispersing the pressure applied by the user, and avoiding skin damage; and when the device is moved back and forth on the skin surface, the thorns 12 are pressed against the skin surface, and the skin is provided with a plurality of contact points. The convex ball 1 will roll in the hemispherical cavity 21, and the relative position of the protrusion 12 and the skin surface is fixed (the contact point between the protrusion 12 and the skin surface is relatively static), and the skin will not be dragged during the movement, so the skin surface will not be damaged, ensuring that the itching is relieved while avoiding skin scratches; at the same time, the skin care device in this solution can also be used to mark the painful area on the patient's skin surface, compared with the traditional questioning and reliance on the patient's verbal description, the diagnosis result is more accurate; the holding part 2, the restraining part 3, and the convex ball 1 in this solution can be easily disassembled and easy to clean and replace.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
