Background Art

[0003] Treatment head is a medical device for generating an electric current in the subcutaneous fat layer by a micro needle, thereby destroying fat cells and reducing fat. Since it is necessary to generate an electric current, it is possible that the temperature of the skin rises. In order to avoid burns on the surface skin or reduce the pain sensation of the skin during treatment, it is usually necessary to cool the surface skin. In the prior art, generally, a cooling member is provided at the contact portion between the treatment head and the skin, and the temperature of the cooling member is reduced by semiconductor cooling to reduce the temperature of the surface skin. Therefore, in the conventional Treatment device control method, only the cooling power of the semiconductor can be controlled, and thus a sufficient cooling effect on the skin can be obtained during treatment. However, while being limited by the power of the semiconductor, the cooling rate of the cooling member is also limited, and such cooling efficiency is usually not high, making it difficult to meet the needs of skin cooling during treatment.

[0024] The present application Treatment device submits a control method of

[0025] In the embodiments of the present application, referring to FIGS. 3 and 4, the Treatment device control method ofTreatment device is applied to Treatment device includes a microneedle 20 and a Treatment head with a treatment surface, and refrigerant conveyance control means for conveying refrigerant to the treatment surface, Treatment device The control method of

[0026] The refrigerant conveyance control means may include a refrigerant tank for storing refrigerant and an air pump for pumping out the refrigerant from the refrigerant tank. The refrigerant conveyance amount can be adjusted by adjusting the power of the air pump. The refrigerant vaporized by the pressure generated by the natural vaporization of the refrigerant is pushed out, and may further include a gas valve with adjustable opening for changing the refrigerant conveyance amount by adjusting the opening degree of the gas valve. The control of the air pump power and the control of the gas valve opening degree belong to the prior art, and their structures and principles will not be described repeatedly. The refrigerant may be a gas such as hydrogen gas, nitrogen gas or helium gas, and is stored in the storage tank in a liquid state. The first preset mode may be to continuously convey refrigerant to the treatment surface until the microneedle 20 stops operating when the microneedle 20 is in the operating state. The treatment surface is the surface in contact with the skin. When the microneedle 20 operates, the microneedle 20 first pierces the skin and reaches the subcutaneous fat layer, and then starts to emit radio frequency current, thereby being able to destroy subcutaneous fat cells and play a role in reducing fat. When the refrigerant is conveyed to the treatment surface, it acts directly on the skin. The microneedle 20 being in the operating state means that the microneedle 20 has been inserted into the skin and has not been withdrawn.

[0027] Referring to FIGS. 3 and 4, in one embodiment, the first preset mode is that the refrigerant conveyance control means continuously conveys refrigerant to the treatment surface within the first preset time and circulates so that the refrigerant conveyance control means stops the conveyance of refrigerant within the second preset time, or Treatment device is Treatment headFurther comprising a temperature detector provided thereon, the temperature detector acquires the temperature of the skin, and when the temperature of the skin exceeds the first preset temperature, the refrigerant conveyance control means conveys refrigerant to the treatment surface, and when the temperature of the skin is below the first preset temperature, stops the conveyance of refrigerant to the treatment surface, or The refrigerant conveyance control means is to inject refrigerant onto the treatment surface a preset number of times.

[0028] Both the first preset time and the second preset time constitute a circulation cycle, and within the operating time of the microneedles 20, refrigerant is continuously supplied in this circulation cycle, thereby protecting the skin so that the skin temperature is neither too low nor too high and does not cause damage to the skin, and reducing pain.

[0029] The temperature detector may be an infrared temperature sensor and may be provided in the microneedle cavity 11, whereby the temperature of the skin can be measured through the refrigerant hole. The temperature detector may also be a thermistor. A thermistor is provided at the tip of a certain microneedle 20, and the microneedle 20 provided with the thermistor is arranged shorter than the other microneedles 20. When the microneedle 20 acts, the microneedle 20 does not penetrate the skin but only abuts against the skin surface, whereby the temperature data of the skin can be obtained by measuring the resistance of the thermistor. When the temperature of the skin exceeds the first preset temperature, refrigerant is conveyed to the skin, and when the temperature of the skin is below the first preset temperature, the conveyance of refrigerant is stopped, thereby saving refrigerant, Treatment device and the intelligence can be enhanced. The first preset temperature may be a temperature range. From the lower temperature to the higher temperature, when exceeding the upper limit of the range, the injection of refrigerant starts, and from the higher temperature to the lower temperature, when exceeding the lower limit of the range, the injection of refrigerant stops. Thereby, frequent injection of refrigerant can be avoided and the refrigerant conveyance control means can be protected.

[0030] In the operating state of the microneedles, the refrigerant conveyance control means injects refrigerant onto the treatment surface a preset number of times, and the preset number may be set manually, Treatment deviceIt may be fixed during production, but is not limited here. Here, the rules of injection are also not limited, that is, as the operation of the micro needle proceeds, the injection frequency may be gradually increased, and finally, when the injection reaches the preset number of times, the operation may be completed. At the start of the operation of the micro needle, the injection frequency may be high, and as the operation of the micro needle proceeds, the injection frequency may gradually decrease. Finally, when the injection reaches the preset number of times, the micro needle may complete the operation simultaneously. It may also inject randomly.

[0031] Referring to FIGS. 3 and 4, in one embodiment, before the micro needle 20 starts operating, the refrigerant conveyance control means conveys the refrigerant to the treatment surface in a second preset mode. Before the micro needle 20 operates, the skin is at room temperature. At this temperature, the pain receptors on the skin function normally and can sensitize the pain sensation of the skin. At this time, supplying the refrigerant can lower the temperature of the skin, reduce the activity of the pain receptors on the skin, thereby reducing the pain sensation and improving the user's experience. Before the micro needle 20 starts operating refers to before the micro needle 20 starts emitting the radio frequency current to destroy the subcutaneous fat cells. At this time, the micro needle 20 may not penetrate the skin, or may penetrate the skin.

[0032] Referring to FIGS. 3 and 4, in one embodiment, the second preset mode is that the refrigerant conveyance control means conveys the refrigerant to the treatment surface within a third preset time, or Treatment device is Treatment head further provided with a temperature detector provided thereon. The temperature detector acquires the temperature of the skin, and until the temperature of the skin becomes lower than the second preset temperature, the refrigerant conveyance control means continues to convey the refrigerant to the treatment surface.

[0033] The second preset mode may be to continuously convey the refrigerant within a third preset time to ensure a decrease in the skin temperature, thereby reducing the pain sensation. The second preset mode may be to supply the refrigerant until the temperature detector detects that the skin temperature is lower than the second preset temperature. For the setting method of the temperature detector, refer to the above embodiments.

[0034] Referring to FIGS. 3 and 4, in one embodiment, after the micron needle 20 stops operating, the refrigerant conveyance control means conveys the refrigerant to the treatment surface in a third preset mode.

[0035] Even after the micron needle 20 stops operating, the temperature of the subcutaneous fat layer remains high, and the heat of the subcutaneous fat layer gradually conducts to the dermis layer, thereby increasing the activity of pain receptors in the skin and potentially causing pain to the user. By continuously conveying the refrigerant after the micron needle 20 stops operating, it is possible to further ensure that the skin temperature remains low for a long time. After the micron needle 20 stops operating refers to after the micron needle 20 stops discharging the radio frequency current and completes the destruction of the subcutaneous fat cells. At this time, the micron needle 20 may still be in the skin or may already have been withdrawn from the skin.

[0036] Referring to FIGS. 3 and 4, in one embodiment, the third preset mode is that the refrigerant conveyance control means conveys the refrigerant to the treatment surface within a fourth preset time, or Treatment device is, Treatment head further includes a temperature detector provided thereon. The temperature detector acquires the skin temperature, and the refrigerant conveyance control means continues to convey the refrigerant to the treatment surface until the skin temperature becomes equal to or lower than the third preset temperature.

[0037] The third preset mode may be to convey the refrigerant within the fourth preset time to further lower the skin temperature, thereby canceling out the heat introduced into the subcutaneous fat layer. It may also be to detect the skin temperature with a temperature detector and convey the refrigerant until the skin temperature reaches or drops below the third preset temperature, which contributes to the conservation of the refrigerant.

[0038] Referring to FIGS. 3 and 4, in one embodiment, Treatment device further includes negative pressure control means, Treatment head a negative pressure groove 14 is further provided thereon. The negative pressure groove 14 is provided on the treatment surface, the opening of the negative pressure groove 14 faces the treatment surface, and the negative pressure control means is used to supply negative pressure to the negative pressure groove 14. Treatment device The control method is that before the microneedle 20 starts operating, the negative pressure control means starts to provide negative pressure, and / or Treatment device is Treatment head further includes a temperature detector provided thereon. After the microneedle 20 stops operating, the temperature detector acquires the skin temperature. When the skin temperature reaches or drops below the fourth preset temperature, the negative pressure control means further stops supplying negative pressure to the negative pressure groove 14.

[0039] Before the microneedle 20 starts operating and before the microneedle 20 pierces the skin, the negative pressure control means supplies negative pressure to the negative pressure groove 14. Since the treatment surface faces the skin, when there is negative pressure in the negative pressure groove 14, the skin Treatment head is adsorbed and fixed, thereby stabilizing the piercing direction of the microneedle 20. Treatment headAfter the operation of stops, in order to further transport the refrigerant to lower the temperature of the skin, a temperature detector is arranged to detect the temperature of the skin. Until the temperature of the skin becomes lower than the fourth preset temperature, the negative pressure is further released, making it easier for the user to continuously supply the refrigerant to the skin. For the setting method of the temperature detector, refer to the above embodiment. The fourth preset temperature can be set equal to the third preset temperature. The negative pressure control means may be a mechanism having an air pump that extracts the gas in the negative pressure tank 14 so as to supply negative pressure to the negative pressure tank 14. The control structure and method of the air pump belong to the prior art. The negative pressure control means may also be a suction air bag that generates negative pressure by the user pressing the suction air bag, sucks the gas in the negative pressure groove 14, and supplies negative pressure to the negative pressure groove 14.

[0040] Referring to FIGS. 3 and 4, in one embodiment, Treatment head a negative pressure pipe 40 is provided thereon. The negative pressure pipe 40 communicates with the negative pressure groove 14, and the negative pressure control means communicates with the negative pressure pipe 40. Treatment device Specifically, the control method of is that before the microneedle 20 starts to operate, the negative pressure control means starts to extract the gas in the negative pressure groove 14 through the negative pressure pipe 40 and supplies negative pressure to the negative pressure groove 14, and / or Treatment device is Treatment head further provided with a temperature detector provided thereon. After the microneedle 20 stops operating, the temperature detector obtains the temperature of the skin. When the temperature of the skin becomes lower than or equal to the fourth preset temperature, the negative pressure control means stops extracting the gas in the negative pressure groove 14 through the negative pressure pipe 40, thereby stopping the supply of negative pressure to the negative pressure groove 14.

[0041] The negative pressure pipe 40 is arranged so as to easily communicate the negative pressure control means and the negative pressure groove 14. For the installation of the temperature detector, refer to the above embodiment. Referring to FIG. 1, the negative pressure pipe 40 Treatment head is provided outside the housing 10 of , thereby facilitating communication with the piping of the negative pressure control means. Referring to FIGS. 5 to 7, the negative pressure pipe 40 may also be provided inside the housing 10, thereby preventing the wiring of the negative pressure pipe 40 from blocking the user's line of sight and facilitating the user to treat the patient.

[0042] Referring to FIGS. 1 to 9, in one embodiment, Treatment head includes a housing 10 and a refrigerant pipe 30. A micro-needle cavity 11 is provided in the housing 10. A micro-needle 20 is attached to the micro-needle cavity 11. The refrigerant pipe 30 communicates with the micro-needle cavity 11. A treatment surface is provided on the housing 10. A micro-needle passage opening 12 is provided in the treatment surface. The micro-needle 20 protrudes from the treatment surface through the micro-needle passage opening 12. A refrigerant hole 15 is further provided in the treatment surface, or the gap between the micro-needle passage opening 12 and the micro-needle 20 is arranged as a ventilation gap. The refrigerant hole 15 penetrates the housing 10 where the treatment surface is located and communicates with the micro-needle cavity 11. Treatment device The control method of specifically, the refrigerant conveyance control means communicates with the refrigerant pipe 30. When the micro-needle 20 is in an operating state, the refrigerant conveyance control means conveys refrigerant to the refrigerant pipe 30 in a first preset mode. The refrigerant pipe 30 conveys the refrigerant to the micro-needle cavity 11, and the refrigerant flows to the treatment surface through the refrigerant hole 15 or the ventilation gap.

[0043] Via the refrigerant pipe 30, it becomes easier for the refrigerant conveyance control means to convey the refrigerant to the treatment surface. When the refrigerant pipe 30 communicates with the micro needle cavity 11, the refrigerant conveyance control means communicates with the refrigerant pipe 30, that is, communicates with the micro needle cavity 11, and conveys the refrigerant to the micro needle cavity 11. Since the refrigerant hole 15 penetrates the housing 10 and communicates with the micro needle cavity 11 and is provided on the treatment surface, the refrigerant can pass through the refrigerant hole 15 and diffuse to the treatment surface, and the refrigerant can be sent to the treatment surface. The refrigerant can also diffuse from the ventilation gap to the treatment surface. As shown in FIG. 2, since the micro needle 20 is usually thin and soft and needs to be supported to prevent it from being bent during the process of piercing the skin, a guide rib 13 is provided on the micro needle passing port 12 to support the micro needle 20. Of course, referring to FIG. 9, the refrigerant pipe 30 does not have to communicate with the micro needle cavity 11. In the embodiment shown in FIG. 9, a needle outlet groove for accommodating the needle outlet post 16 is provided on the treatment surface, and the refrigerant pipe 30 communicates with the needle outlet groove, thereby conveying the refrigerant to the treatment surface and cooling the skin.

[0044] Referring to FIG. 1, in one embodiment, Treatment device is, Treatment head further provided with a pressure sensor provided thereon, Treatment device The control method of specifically, the pressure sensor obtains the pressure between the treatment surface and the skin, and when the pressure between the treatment surface and the skin is equal to or higher than the first preset pressure, the refrigerant conveyance control means conveys the refrigerant to the treatment surface in the second preset mode, or Treatment device further includes a negative pressure control means, Treatment head A negative pressure groove 14 is further provided thereon, the negative pressure groove 14 is provided on the treatment surface, the opening of the negative pressure groove 14 faces the treatment surface, and the negative pressure control means is used to supply negative pressure to the negative pressure groove 14, Treatment device The control method of specifically, after the negative pressure control means starts to supply negative pressure to the negative pressure groove 14, the refrigerant conveyance control means conveys the refrigerant to the treatment surface in the second preset mode.

[0045] The pressure sensor may be provided on the treatment surface. To improve the contact effect between the treatment surface and the skin, the pressure sensor may be a diaphragm pressure sensor, or the pressure sensor may be a micro switch. Triggering the micro switch indicates that the contact pressure between the skin and the treatment surface is sufficient. Since it is necessary to pierce the skin with the micro needle during use, it is necessary to press the treatment surface against the skin with a certain pressure so that the micro needle is accurately pierced and does not deviate from the desired treatment position. To facilitate the user's operation, since the pressure is sufficient, the pressure sensor can prompt the user that they can start the treatment. The refrigerant conveyance control means can save the refrigerant by supplying the refrigerant after the pressure becomes sufficient. When the pressure is insufficient, the user does not start the treatment and may still be in the preparation stage, so releasing the refrigerant too early will lead to waste.

[0046] The negative pressure groove 14 can make the treatment surface adhere closely to the skin, and the user can start the treatment only after the treatment surface adheres closely to the skin. Therefore, the negative pressure conveyance control means can provide the refrigerant to cool after negative pressure exists in the negative pressure groove 14, thereby saving the refrigerant and avoiding the early release of the refrigerant.

[0047] Referring to FIGS. 1, 8, and 9, in one embodiment, a micro needle passage opening 12 for protruding the micro needle 20 from the treatment surface and piercing the skin is provided on the treatment surface, and a ventilation gap is provided between the micro needle passage opening 12 and the micro needle 20. Treatment device The control method specifically is that when the micro needle 20 is in the operating state, the refrigerant conveyance control means conveys the refrigerant to the ventilation gap in the first preset mode, and the refrigerant flows through the ventilation gap to the treatment surface, or A refrigerant hole 15 is provided on the treatment surface. Treatment device The control method specifically is that when the micro needle 20 is in the operating state, the refrigerant conveyance control means conveys the refrigerant to the refrigerant hole 15 in the first preset mode, and the refrigerant flows through the refrigerant hole 15 to the treatment surface, or A needle exit groove is provided on the treatment surface, and the needle exit groove is flush with the treatment surfaceGroove having a specific size is arranged as Treatment device Specifically, the control method is that when the microneedle 20 is in the operating state, the refrigerant conveying control means conveys the refrigerant to the needle outlet groove, and the refrigerant flows through the needle outlet groove to the treatment surface.

[0048] As shown in FIG. 9, the notch of the opened microneedle groove is exactly the treatment surface, thereby expanding the contact area between the refrigerant and the skin and enhancing the cooling effect. The refrigerant pipe 30 can communicate with the microneedle groove, whereby it is possible for the refrigerant control conveying means to convey the refrigerant to the needle outlet groove.

[0049] It is also possible to individually provide a refrigerant cavity so as to control the flow of the refrigerant by outputting the refrigerant to the refrigerant hole 15. For example, when the cover plate closes the opening of the needle outlet groove and several refrigerant holes 15 are provided in the cover plate, the cover plate, the side wall and the bottom wall of the needle outlet groove can constitute the refrigerant cavity. At this time, the refrigerant pipe communicates with the refrigerant cavity, and the refrigerant is discharged from the refrigerant hole 15 and flows to the treatment surface.
