The present application provides a control method for a treatment device.
In the embodiment of the present application, as shown in
The coolant delivery control mechanism can have a coolant tank to store the coolant and an air pump to pump out the coolant from the coolant tank, and adjust the coolant delivery volume by adjusting the power of the air pump; it can also have a valve with an adjustable opening. The atomized coolant is pushed out through the pressure generated by the natural atomization of the coolant, and the coolant delivery volume is changed by adjusting the opening degree of the valve. The control for the power of the atomizing pump and the control for the opening degree of the valve belong to the existing technology, and the structure and principle will not be described again. The coolant can be a gas from at least one of hydrogen, nitrogen and helium and so on, which is stored in liquid form in the storage tank. The first preset mode can be that the coolant is continuously delivered to the treatment surface when the needle 20 is in a working state until the needle 20 stops working. The treatment surface is a surface in contact with the skin. When the needle 20 works, the needle 20 first penetrates the skin and reach the subcutaneous fat layer, and then start to release radio frequency current, thereby destroying subcutaneous fat cells and reducing fat. When the coolant is delivered to the treatment surface, it can directly act on the skin. When the needle 20 is in the working state, it means that the needle 20 has penetrated into the skin and has not been withdrawn.
Referring to
Alternatively, the treatment device also includes a temperature detector. The temperature detector is provided on the treatment tip. The temperature detector obtains the temperature of the skin. When the temperature of the skin exceeds a first preset temperature, the coolant delivery control mechanism delivers the coolant to the treatment surface, and when the temperature of the skin is lower than the first preset temperature, the coolant delivery control mechanism stops delivering the coolant to the treatment surface; or the coolant delivery control mechanism sprays the coolant to the treatment surface a preset number of times.
The first preset time and the second preset time form a cycle. During the working time of the needle 20, the coolant is continuously supplied in this cycle to prevent the skin temperature from being too low or too high, thereby protecting the skin from damage and reducing pain.
The temperature detector can be an infrared temperature sensor, which can be provided in a needle cavity 11, so that the temperature of the skin can be measured through a coolant through the outlet. The temperature detector can also be a thermosensitive resistor. The thermosensitive resistor can be provided at the tip of a certain needle 20, and the needle 20 provided with the thermosensitive resistor is configured to be shorter than the other needles 20. When the needle 20 acts, the needle 20 does not penetrate the skin, but only contacts the skin surface, so that data of the skin temperature can be obtained by measuring the resistance of the thermosensitive resistor. When the skin temperature exceeds the first preset temperature, the coolant is delivered to the skin. When the skin temperature is lower than the first preset temperature, the coolant delivery is stopped. This helps save coolant and improves intelligence of the treatment device. The first preset temperature can be a temperature range. When the temperature goes from low to high and exceeds the upper limit of the range, the coolant injection starts. When the temperature goes from high to low and exceeds the lower limit of the range, the coolant injection stops. This helps avoid frequent injection of coolant, thus protecting the coolant delivery control mechanism.
When the needle is in the working state, the coolant delivery control mechanism sprays the coolant to the treatment surface a preset number of times. The preset number of times can be set manually or fixed when the treatment device is produced, which is not limited here. There is no limit to the injection pattern here, that is, as the needle works, the injection frequency can be gradually increased, and finally when the preset number of injections is reached, the needle completes the work at the same time; it can also be when the needle starts to work, the injection frequency is high. As the needle works, the injection frequency is gradually reduced. Finally, when the preset number of injections is reached, the needle completes the work at the same time; it can also be irregular and random injection.

The second preset mode can be that the coolant is continuously delivered during the third preset time to ensure that the skin temperature is lowered, thereby reducing pain. The second preset mode can also be when the coolant is delivered until the temperature detector detects that the skin temperature is lower than the second preset temperature. The setting method of the temperature detector refers to the above embodiment.
Referring to
After the needle 20 stops working, the temperature of the subcutaneous fat layer is still high, and the heat of the subcutaneous fat layer may gradually be conducted to the dermis layer, thereby increasing the activity of pain receptors in the skin, and causing pain to the user. When the needle 20 stops working, the coolant is continuously delivered, which can further ensure that the skin temperature remains low for a longer period of time. After the needle 20 stops working, it means that the needle 20 stops releasing radio frequency current and completes the destruction of subcutaneous fat cells. At this time, the needle 20 may still be in the skin, or may have been pulled out of the skin.
Referring to
The third preset mode can be that the coolant is delivered during the fourth preset time to further reduce the temperature of the skin, thereby offsetting the heat transferred from the subcutaneous fat layer; it can also be that the temperature of the skin is detected through the temperature detector and the coolant is delivered until the temperature of the skin is less than or equal to the third preset temperature, which is beneficial to saving coolant.
Referring to
Before the needle 20 starts to work and before the needle 20 penetrates into the skin, the negative pressure is provided to the negative pressure groove 14 through the negative pressure control mechanism. Since the treatment surface faces the skin, when there is negative pressure in the negative pressure groove 14, the treatment tip is made to suck the skin tightly and fix on the skin, thereby ensuring the stabilization of the insertion direction of the needle 20. After the treatment tip stops working, the coolant is further delivered to reduce the temperature of the skin, therefore the temperature detector can be configured to detect the temperature of the skin until the temperature of the skin is lower than the fourth preset temperature. Then, the negative pressure is released, so that the user can continuously deliver the coolant to the skin. The setting method of the temperature detector refers to the above embodiment. The fourth preset temperature can be set to be equal to the third preset temperature. The negative pressure control mechanism can be a mechanism with an air pump. The gas in the negative pressure groove 14 is extracted by the air pump to provide the negative pressure to the negative pressure groove 14. The control structure and method for the air pump belong to the existing technology, and the negative pressure control mechanism can also be an air suction bag. The user presses the air suction bag to generate negative pressure and sucks the gas in the negative pressure groove 14 to provide negative pressure to the negative pressure groove 14.
Referring to
The arrangement of the negative pressure tube 40 can facilitate the communication between the negative pressure control mechanism and the negative pressure groove 14. The arrangement of the temperature detector refers to the above embodiment. Referring to
Referring to
The coolant tube 30 can conveniently allow the coolant delivery control mechanism to deliver the coolant to the treatment surface. The coolant tube 30 is communicated with the needle cavity 11. The coolant delivery control mechanism is communicated with the coolant tube 30, that is, communicated with the needle cavity 11, and delivers the coolant into the needle cavity 11. Since the coolant outlet 15 penetrates the housing 10 and is communicated with the needle cavity 11, and provided on the treatment surface, the coolant can pass through the coolant outlet 15 and diffuse to the treatment surface, thereby delivering the coolant to the treatment surface. The coolant can also diffuse onto the treatment surface from the needle-coolant outlet gap. As shown in
Referring to
The pressure sensor can be provided on the treatment surface. The pressure sensor can be a diaphragm pressure sensor to improve the contact effect between the treatment surface and the skin. The pressure sensor can also be a micro switch, which triggers the micro switch to indicate that the contact pressure between the skin and the treatment surface is sufficient. Since the needles need to be inserted into the skin in usage, a certain pressure is required to press the treatment surface against the skin to ensure the accuracy of the needle insertion process and avoid deviation from the desired treatment position during the needle insertion process. The pressure sensor can prompt the user that the pressure is sufficient to start treatment, making it easier for the user to operate. The coolant delivery control mechanism can save coolant by supplying the coolant after the pressure is sufficient, because when the pressure is insufficient, the user will not start treatment and may only be in the preparation stage. At this time, the coolant is released too early, which will lead to waste.
The negative pressure groove 14 can make the treatment surface close to the skin. At the same time, the user will start treatment only after the treatment surface is close to the skin. Therefore, the negative pressure delivery control mechanism provides the coolant after there is negative pressure in the negative pressure groove 14, which can save the coolant and avoid premature release of the coolant.
Referring to
As shown in
When the coolant is outputted to the coolant outlet 15, a separate coolant cavity can also be provided for the coolant to control the flow direction of the coolant. For example, a cover plate is used to close the opening of the needle slot, and a number of coolant outlets 15 are provided on the cover plate. In this way, the cover plate, the side walls and the bottom wall of the needle outlet slot can form a coolant cavity. At this time, the coolant tube is communicated with the coolant cavity, and the coolant is discharged from the coolant outlet 15 and flows toward the treatment surface.
