[0002] In existing medical procedures, such as laser surgery and radiofrequency therapy, the skin surface can overheat due to the energy exposure of the device, leading to skin damage. Existing cooling technologies include contact cooling, spray cooling, and air cooling, but these methods suffer from uneven cooling effects, low cooling efficiency, complex operation, and difficulty in accurately controlling skin temperature.

[0003] The following problems exist in existing skin cooling technologies for medical procedures (such as laser surgery, radiofrequency treatment, etc.): The cooling effect is uneven, causing some skin areas to be overheated or undercooled.

[0004] The cooling efficiency is low and the skin temperature cannot be reduced quickly, which affects the treatment effect and patient comfort.

[0005] The operation is complicated and requires manual adjustment of multiple parameters, which increases the workload of the operator.

[0006] It is difficult to precisely control skin temperature and there is a risk of skin damage. Summary of the Invention

[0007] The technical problem to be solved by the present invention is that the existing technology has problems such as uneven cooling effect, low cooling efficiency, complicated operation, and difficulty in accurately controlling skin temperature.

[0008] To solve the above technical problems, the present invention provides a skin cooling device that integrates dynamic vaporization and phase change material, including: a dynamic liquid supply bubble-free vaporization cooling system, the system including an acoustic atomizer, a nozzle array and a dynamic liquid supply system; a phase change material cooling system, the system including a phase change material layer and a temperature regulating device; a cooling controller for controlling the operating parameters of the dynamic liquid supply bubble-free vaporization cooling system; a temperature sensor for real-time monitoring of the skin surface temperature and the temperature of the phase change material, and feeding back the signal to the cooling controller; a synchronization device for synchronizing the operation of the cooling device with the pulse emission of an energy-type medical device; a liquid delivery device, including a liquid storage tank and a delivery pipeline, for storing and delivering cooling liquid.

[0009] Furthermore, the dynamic liquid supply system adopts a pulse mode to supply liquid and accurately controls the droplet delivery by adjusting the duty cycle.

[0010] Furthermore, the phase change temperature of the phase change material layer is within a skin-safe temperature range.

[0011] Furthermore, the cooling controller is used to control operating parameters such as injection frequency, injection angle and gas flow rate.

[0012] Furthermore, the temperature sensor includes a skin surface temperature sensor and a phase change material temperature sensor.

[0013] A control method using a skin cooling device integrating dynamic vaporization and phase change material according to the present invention comprises the following steps: S1. Preparation phase: Connect the cooling device to the energy-based medical device and configure the cooling device parameters according to treatment needs; pre-cool the phase change material cooling system to below its phase change temperature to ensure that it can quickly absorb heat when treatment begins; S2. Cooling process: Before or simultaneously with the energy-based medical device emitting an energy pulse, the dynamic liquid supply bubble-free vaporization cooling system is activated, and the cooling liquid is atomized by the sonic atomizer and sprayed onto the skin surface for evaporative cooling. At the same time, the phase change material cooling system begins to work. Upon contact with the skin, the phase change material rapidly absorbs heat and undergoes a phase change, thereby achieving a rapid and lasting cooling effect. Based on the temperature feedback from the skin surface, the cooling intensity is dynamically adjusted through the control system to ensure that the skin surface temperature remains within a safe range.

[0018] Advantages of the present invention: 1. Efficient Cooling: The dynamic, bubble-free, vaporized cooling system uses a sonic atomizer to atomize the cooling liquid into tiny droplets. These droplets evaporate quickly upon application to the skin, removing significant heat and achieving rapid cooling. Simultaneously, the phase-change material rapidly absorbs heat and undergoes a phase change upon contact with the skin, further enhancing the cooling effect and ensuring the skin's surface temperature is rapidly reduced and maintained within a safe range.

[0019] 2. Uniform Cooling: The nozzle array design evenly sprays atomized droplets onto the skin surface, avoiding the uneven distribution of coolant that can occur with traditional cooling methods. Furthermore, the uniform contact of the phase change material layer ensures uniform cooling, effectively preventing localized overcooling or overheating of the skin and reducing the risk of skin damage.

[0020] 3. Precision Control: The cooling controller dynamically adjusts operating parameters such as spray frequency, spray angle, and gas flow based on real-time temperature data from the temperature sensor, ensuring that cooling intensity precisely matches skin needs. A synchronization device ensures precise synchronization between the cooling device's operation and the pulse emission of the energy-based medical device, further enhancing cooling accuracy.

[0026] The specific embodiments of the present invention are further described below with reference to the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0027] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Combined with attachment Figure 1-3 As shown, A skin cooling device integrating dynamic vaporization and phase change materials comprises: a dynamic liquid supply bubble-free vaporization cooling system, the system comprising a sonic atomizer, a nozzle array and a dynamic liquid supply system; the dynamic liquid supply system adopts a pulse mode to supply liquid, and precisely controls the droplet delivery by adjusting the duty cycle to ensure that the cooling liquid can be sprayed onto the skin surface in the form of uniform and stable droplets, avoiding the generation of bubbles, thereby improving cooling efficiency and uniformity.

[0030] The dynamic liquid supply system's pulsed mode precisely controls droplet delivery by adjusting the duty cycle, allowing for flexible adjustments to the coolant flow rate and injection frequency based on treatment needs and skin conditions. For example, in the early stages of treatment, when skin temperature is high, the duty cycle can be increased to increase the coolant flow rate and rapidly lower the skin temperature. During treatment, the duty cycle is dynamically adjusted based on changes in skin temperature to ensure a stable and uniform cooling effect. This pulsed mode not only improves cooling efficiency but also reduces coolant waste and lowers operating costs.

[0031] A phase-change material cooling system includes a phase-change material layer and a temperature control device. The phase-change temperature of the phase-change material layer is within the skin-safe temperature range, rapidly absorbing heat and undergoing a phase change upon contact with the skin, achieving a rapid and lasting cooling effect. The temperature control device includes an external cooling system for pre-cooling or re-cooling the phase-change material, ensuring that the phase-change material maintains efficient cooling capabilities throughout treatment.

[0032] The phase change temperature range of the phase change material layer is preferably between 25°C and 35°C. This temperature range ensures that the phase change material quickly absorbs heat and undergoes a phase change after contacting the skin, while avoiding poor cooling effects or skin discomfort caused by excessively high or low phase change temperatures. For example, when the phase change temperature is set at 30°C, the phase change material can quickly absorb heat and undergo a phase change after contacting the skin, quickly reducing the skin surface temperature to a safe range, while avoiding cooling delays caused by excessively high phase change temperatures or excessive cooling of the skin caused by excessively low phase change temperatures.

[0033] Among them, the external cooling system of the temperature regulating device: the external cooling system adopts circulating refrigeration technology to pre-cool or re-cool the phase change material through the circulating flow of refrigerant. This cooling method can quickly reduce the temperature of the phase change material, ensuring that it always maintains efficient cooling capacity during the treatment process. For example, before treatment, the phase change material is cooled to below its phase change temperature through the external cooling system, so that it can quickly absorb heat and undergo phase change at the beginning of treatment, achieving rapid cooling. During the treatment process, the external cooling system can re-cool the phase change material, prolong the duration of its cooling effect, and further improve the cooling efficiency.

[0034] The cooling controller is used to control the operating parameters of the dynamic liquid-supply, bubble-free vaporization cooling system. These parameters include spray frequency, spray angle, and gas flow rate. By precisely controlling these parameters, the cooling intensity can be dynamically adjusted based on different treatment needs and skin conditions, ensuring that the skin surface temperature remains within a safe range.

[0035] The temperature sensor is used to monitor the skin surface temperature and the temperature of the phase change material in real time, and feed back the signal to the cooling controller; through the real-time feedback mechanism, the cooling controller can dynamically adjust the cooling parameters according to temperature changes, further improving the accuracy and safety of cooling.

[0036] A synchronization device is used to synchronize the operation of the cooling device with the pulse emission of the energy-type medical device; the synchronization device includes a signal receiver for receiving the pulse emission signal of the energy-type medical device, ensuring that the cooling device can be started before or at the same time as the energy pulse emission to achieve precise cooling control.

[0037] The liquid delivery device includes a liquid storage tank and a delivery pipeline for storing and delivering cooling liquid. The liquid storage tank and the delivery pipeline are made of corrosion-resistant materials to adapt to different cooling liquids and ensure the stability and reliability of the device.

[0038] A control method using a skin cooling device integrating dynamic vaporization and phase change material according to the present invention comprises the following steps: S1. Preparation stage: Connect the cooling device to the energy-based medical equipment and configure the parameters of the cooling device according to the treatment needs; pre-cool the phase change material cooling system to below its phase change temperature to ensure that it can quickly absorb heat when treatment begins.

[0039] S2. Cooling process: Before or at the same time as the energy-type medical device emits an energy pulse, the dynamic liquid supply bubble-free vaporization cooling system is started, and the cooling liquid is atomized by the ultrasonic nebulizer and sprayed onto the skin surface for evaporative cooling; at the same time, the phase change material cooling system starts working, and the phase change material quickly absorbs heat and undergoes phase change after contacting the skin, thereby achieving a fast and lasting cooling effect; based on the temperature feedback of the skin surface, the cooling intensity is dynamically adjusted through the control system to ensure that the skin surface temperature is maintained within a safe range.

[0040] S3. Ending stage: After the energy-based medical device completes the treatment, continue to operate the cooling device for a period of time to ensure that the skin surface temperature returns to normal levels; clean the cooling liquid remaining on the skin surface, and perform subsequent skin care.

[0041] The nozzle array includes multiple nozzles for evenly spraying atomized droplets onto the skin surface. The nozzle array design ensures uniform distribution of cooling liquid across the skin surface, preventing localized overcooling or overheating and further improving the uniformity of the cooling effect.

[0042] The cooling controller further includes a user interface for displaying the skin surface temperature and the temperature of the phase change material and allowing an operator to manually adjust the cooling parameters.

[0043] The cooling controller further includes a user interface that displays the skin surface temperature and the temperature of the phase change material, and allows the operator to manually adjust cooling parameters. This user interface improves the device's ease of operation and flexibility, allowing medical personnel to adjust cooling parameters in real time based on the patient's actual condition and treatment needs, ensuring optimal cooling results. For example, during treatment, if the skin surface temperature approaches the upper safety limit, medical personnel can manually increase the coolant flow rate or adjust the spray frequency through the user interface to promptly lower the skin temperature and ensure patient safety.

[0044] The skin cooling device also includes a safety locking mechanism that automatically stops the supply of coolant when the skin surface temperature exceeds a preset safety range, preventing overcooling or frostbite of the skin and ensuring patient safety.

[0045] The skin cooling device also includes a cleaning system for automatically cleaning the nozzle array and delivery pipeline after the treatment is completed; preventing blockage or contamination caused by residual cooling liquid, extending the service life of the device and ensuring safety for the next use.

[0046] The skin cooling device also includes a data recording system for recording the skin surface temperature and the temperature changes of the phase change material during treatment; providing medical personnel with detailed treatment data to facilitate subsequent analysis and optimization of treatment plans.

[0047] The skin cooling device also includes a remote monitoring system that allows medical personnel to remotely monitor and adjust cooling parameters, improving the flexibility and convenience of treatment, and is particularly suitable for telemedicine or complex treatment scenarios.

[0048] The remote monitoring system's expanded functionality includes the ability to not only remotely monitor cooling parameters but also transmit real-time data on skin surface temperature and the temperature of the phase change material. Medical personnel can view the temperature curve during treatment in real time via a remote terminal device (such as a mobile phone, tablet, or computer), promptly identifying any anomalies and making adjustments. Furthermore, the remote monitoring system can be configured with an alarm function. When the skin surface temperature exceeds a safe range, it automatically sends an alert to medical personnel, prompting them to take timely action, further improving the safety and reliability of treatment.

[0049] Working Principle Process Connect the cooling device to the energy-based medical device and configure the parameters of the cooling device according to treatment needs.

[0050] Pre-cool the phase change material cooling system to below its phase change temperature to ensure it can quickly absorb heat when treatment begins. Start the cooling controller to initialize each system and prepare for the cooling process.

[0051] During the cooling process, before or simultaneously with the energy-based medical device emitting an energy pulse, the cooling controller activates the dynamic liquid-supply, bubble-free vaporization cooling system. The sonic nebulizer atomizes the cooling liquid into tiny droplets, which are evenly sprayed onto the skin surface through a nozzle array. The droplets rapidly evaporate on the skin surface, removing a significant amount of heat and achieving rapid cooling. Simultaneously, the phase-change material cooling system activates. Upon contact with the skin, the phase-change material rapidly absorbs heat and undergoes a phase change, further enhancing the cooling effect and ensuring that the skin surface temperature remains within a safe range. A temperature sensor monitors the skin surface temperature and the phase-change material temperature in real time and provides feedback to the cooling controller. Based on this temperature feedback, the cooling controller dynamically adjusts cooling parameters, such as spray frequency, spray angle, and gas flow rate, to adapt to changes in skin temperature and ensure a stable and uniform cooling effect. A synchronization device receives the pulse emission signal from the energy-based medical device, ensuring precise synchronization of the cooling device's operation with the energy pulse emission, further improving cooling accuracy.

[0052] Finally, after the energy-based medical device completes treatment, the cooling controller continues to operate the cooling device for a period of time to ensure that the skin surface temperature returns to normal. The cleaning system automatically activates to clean the nozzle array and delivery pipes to prevent blockage or contamination caused by residual cooling liquid. The data recording system records changes in skin surface temperature and the temperature of the phase change material during treatment, providing medical personnel with detailed treatment data. Medical personnel can adjust cooling parameters or review treatment data as needed through the remote monitoring system. After completing these steps, the cooling device is turned off and subsequent skin care procedures are performed.
