[0002] The polychromatic pulse light source released by a high-energy flash lamp under high pressure is called Intense Pulsed Light (IPL). It consists of incoherent, non-parallel broad-spectrum light, with a wavelength of usually 400nm-1200nm. Intense pulsed light technology can release high energy in the form of light radiation in a very short time (tens to hundreds of microseconds), thereby generating intense pulsed light with extremely high peak power (up to megawatt level).

[0003] Based on the characteristics of intense pulsed light: the wavelength range basically covers the main absorption peaks of various target color groups in the skin (such as melanin, hemoglobin and water, etc.), and the intense pulsed light has photothermal effect through high-intensity pulsed light, etc., intense pulsed light is widely used in the treatment of skin diseases or dry eye syndrome and other diseases.

[0004] Different diseases require different light intensities and wavelengths. Light intensity is a key parameter in intense pulsed light (IPL) therapy, which directly affects the effect and safety of treatment. However, since the equivalent resistance of an intense pulsed light source decreases over time, its discharge process cannot be equivalent to a conductor with a constant resistance, resulting in the difficulty for the intense pulse energy output device to accurately output energy corresponding to the required light intensity or required power during the entire discharge process.

[0048] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0049] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0050] In the field of using intense pulsed light technology to treat skin diseases, during a treatment process where the probe contacts a designated skin area, a constant light intensity has a better treatment effect and is more controllable, and is less likely to cause the patient to be burned by excessive light intensity. However, due to the resistance characteristics of the pulse light source, the energy output during the discharge of the pulse light source varies. When the discharge characteristics of the pulse light source cause the pulse light source to be unable to provide a constant light intensity within the time of a pulse, the treatment effect is affected to a certain extent.

[0051] Different skin conditions can withstand different light intensities. The light intensity output by pulsed light source discharge is uncontrollable and can easily cause burns to skin in some conditions.

[0052] In view of the above problems, the embodiment of the present application provides a pulse energy output method to obtain the required power corresponding to the light intensity required for the user's treatment project, and calculate the equivalent power of the required power based on the discharge characteristics of the pulse light source. The equivalent power does not change during the duration of the energy output, providing patients with a constant light intensity, ensuring the safety of the operation process, and the total amount of energy output at the equivalent power during the duration is the same as the total energy output by the original energy output method. The pulsed light outputs energy at a constant equivalent power during the pulse duration without change, providing a basis for accurately outputting energy corresponding to the required power, and meeting the energy requirements of specific patients for treatment. On the other hand, by identifying the skin condition of the treatment area, a target equivalent power that matches the skin condition can be selected, and output according to the target equivalent power, further ensuring the safety of the treatment.

[0053] The pulse energy output method is applied to the control circuit of the pulse energy device. The control circuit can send instructions to other components to control other components to perform specific steps, such as sending instructions to sensors, and the sensors respond to the instructions to collect relevant data, such as image acquisition devices, color sensors, brightness sensors, etc. The control circuit obtains the relevant data collected by the sensors. The control circuit can also store and execute pre-set step processes, analyze and calculate the collected data, send instructions to control other components, and control the components of the pulse energy device to cooperate with each other to complete the functions specified by the user. Generally, the pulse energy device also includes a pulse light source, a probe, a display screen, a physical button, at least one functional circuit, a chip integrating a functional circuit and / or a software module, a hardware module, etc. The probe is used to contact a specified area for energy output.

[0054] Figure 1 is a flow chart of the steps of the pulse energy output method proposed in the embodiment of the present application, such as Figure 1 As shown, the steps include:

[0055] S101: Determine the duration and required power corresponding to the energy output item selected by the user.

[0056] Users can input energy output items through the display screen or physical buttons.

[0057] For example, energy output projects can be freckle removal, red blood streak treatment, inflammation treatment, etc. Different treatment projects require different light intensities. Since the pulse light generated during the discharge of the pulse light source decays over time, the light intensity output by the probe during actual operation cannot meet the requirements of the energy output project.

[0058] For example, the pre-established associations among energy output items, required power and duration can be stored, the associations corresponding to the user input instructions can be detected, and the duration and required power corresponding to the execution of the current energy output program can be determined. The duration and required power directly input by the user can also be received.

[0059] S102: Based on the required power, a discharge characteristic distribution of a pulse light source obtained in advance is brought into the discharge, and at least one equivalent power corresponding to the required power is obtained when the pulse light source discharges according to the duration.

[0060] Figure 2 FIG. 1 is a schematic diagram of the discharge characteristic distribution of a pulse light source obtained by an example of the present application. The discharge characteristic distribution indicates the effective energy range of the intense pulse light during the discharge process, such as Figure 2 As shown, during the discharge process of the pulse light source, the effective energy output by the pulse light source decreases over time, and it is difficult to maintain a stable energy output, which has a certain impact on the treatment effect.

[0061] Based on the required power, a discharge characteristic distribution of the pulse light source obtained in advance is brought into the calculation of the equivalent power. One implementation method may include: calculating the total energy accumulated in the effective energy range of the pulse light source at a specific required power. Figure 3 This is an example of an application Figure 2 The schematic diagram of the discharge characteristic distribution corresponding to the equivalent energy power is shown in Figure 2 and Figure 3 As shown, the total energy corresponding to the current energy output demand can be obtained by calculating the area of ​​the energy bar chart in the discharge characteristic distribution diagram. Then, on the basis of a certain total energy and duration, the equivalent power is determined, and the product of the equivalent power and duration is equivalent to or the same as the total energy.

[0062] For example, assuming that Figure 2 The discharge characteristic distribution shown in the figure is calculated, and the total energy output of the pulse light within the pulse duration of 20s is S , is the pulse duration 20s, It is the power corresponding to different moments in the pulse duration. S =S , is the equivalent power.

[0063] In one example, the duration may be divided to obtain different equivalent powers.

[0064] Figure 4 This is an example of an application Figure 2 The schematic diagram of the discharge characteristic distribution corresponding to different equivalent powers is shown in FIG. Figure 4As shown in the figure, the corresponding equivalent energy can be obtained by calculating the area of ​​the energy bar graph in different time ranges. Taking t1 and t2 as the dividing points, the equivalent energy of the pulse light in the time period t0-t1 is calculated as equivalent energy 1, and the equivalent energy of the pulse light in the time period t0-t3 is calculated as equivalent energy 4. Assume that the pulse light output is carried out according to the required power corresponding to the energy output project, and the discharge characteristics of the pulse light are distributed as follows Figure 2 , Figure 3 , Figure 4 As shown, different equivalent powers corresponding to the required power can be calculated.

[0065] S103: Responding to the user's instruction to start outputting pulse energy, the skin condition of the designated skin area is identified in a preset manner.

[0066] The preset method of identifying the skin condition of the specified skin area may include: identifying the skin condition of the specified skin area through sensors and other methods; other methods include accepting skin color grade, degree of lesions, etc. input by users or other devices.

[0067] Skin condition can include skin color, whether the skin is damaged, etc. Different skin colors have different melanin, so the safety energy corresponding to different skin colors is also different.

[0068] In the specific implementation process, an image acquisition device may be used to acquire an image of a designated skin area, perform image analysis, and determine the skin condition. Alternatively, a color sensor and a brightness sensor may be used to acquire data on the target skin area and calculate the skin condition.

[0069] S104: Selecting a target equivalent power matching the skin condition from the at least one equivalent power.

[0070] A statistical model or other method can be established for historical data to obtain the optimal energy range for skin with different skin colors. Historical data includes: pulse light energy of treatment, treatment effect, whether there is burns, etc. Establish a corresponding relationship between different skin colors and the optimal energy range.

[0071] When the skin condition of the specified skin area of ​​the current user is identified, the skin data closest to the skin condition in the database is compared with the different equivalent filters calculated above and the optimal energy range, and the equivalent power that best solves the center value of the optimal energy range is selected as the target equivalent power.

[0072] The target equivalent power determined in the embodiment of the present application not only meets the required power corresponding to the energy output item selected by the user, but also matches the user's matching status, thereby avoiding hazards such as burns to the treatment area caused by inappropriate light intensity output.

[0073] Continue to refer Figure 4, if the calculated target equivalent power is equivalent power 2, pulse light can be output at t1, or the light beam can be blocked from t0 to t1, and the target equivalent power can be output in the same way to meet the duration, so as to achieve the target equivalent power output light intensity and meet the requirement of unchanged total output energy.

[0074] S105: Controlling the pulse light source to output energy within the duration according to the target equivalent power.

[0075] The light source for the pulse device to output energy includes a xenon lamp.

[0076] The target equivalent power does not change during the duration of energy output, and the output energy maintains a stable light intensity. The stable light intensity acting on the designated area is safer and more reliable. Treatment with stable light intensity can better guarantee the treatment effect. At the same time, compared with the total energy output by the original pulse light natural attenuation method, the total energy output according to the energy output method of equivalent power does not change, which further guarantees the treatment effect.

[0077] The embodiment of the present application also proposes a specific process for implementing step S105, which detects the real-time voltage and calculates the actual discharge current to achieve the current energy output demand based on maintaining equivalent power. The constant current output of the regulating circuit is directly used to control the pulse light source to output energy with the actual discharge current. This is simple and fast, requires less circuit modification, and is easy to implement.

[0078] Step S105 includes sub-steps:

[0079] S1051: Collecting the actual voltage of the pulse light source.

[0080] A control circuit is set to connect the voltage sensor, the voltage sensor is connected to the pulse light source, and a voltage collection instruction is sent to the voltage sensor, and the voltage sensor collects the actual voltage at both ends of the pulse light source.

[0081] The control circuit receives the real-time voltage of the pulse light source uploaded by the voltage sensor at preset time intervals.

[0082] In one example, during the discharge duration of a pulse light source, an instruction to periodically collect voltage can be sent to a voltage sensor. The voltage sensor responds to the instruction, collects the actual voltage across the pulse light source at preset intervals and uploads it to the control circuit. The control circuit adjusts the current based on the voltage collected in real time, thereby determining that the power output during the discharge duration of the pulse light source is equivalent power, thereby ensuring that the light intensity output does not change.

[0083] S1052: Calculate actual discharge current by using the pulse light source to achieve the discharge target of the equivalent power based on the actual voltage.

[0084] S1053: Control the pulse device to output energy according to the actual discharge current.

[0085] Based on the above exemplary implementation of periodically detecting the pulse power supply voltage to control the pulse light source to output the same power as the equivalent power, the present application further proposes a specific implementation process of controlling the pulse light source to output the same power as the equivalent power during the duration of the pulse light source outputting the pulse light, including:

[0086] K11: Calculate the actual discharge current corresponding to the current time.

[0087] K12: Output energy according to the actual discharge current corresponding to the current time, and determine whether the time difference between the current time and the start time of the light pulse exceeds the duration.

[0088] K13: If the time difference exceeds the duration, end the energy output.

[0089] K14: If the time difference does not exceed the duration, the actual voltage of the pulse light source at the next moment is collected to calculate the actual discharge current of the pulse light source at the next moment; the actual voltage at the next moment is the real-time voltage after the pulse light source outputs energy at the current time.

[0090] Figure 5 This is a flowchart of an example of calculating the actual discharge current within the duration of a pulse light source discharge. Figure 5 As shown, the pulse light source is powered on and starts to emit light, responds to an instruction to output pulse light once, and calculates the equivalent power corresponding to the required power issued by the instruction. A timer can be set to detect that the pulse light source starts to emit light, read the first time record of the timer, if the first time record does not exceed the duration of the pulse light, read the actual voltage of the pulse light source collected by the voltage sensor, combine the actual voltage with the equivalent power to calculate the actual discharge current, and control the pulse light source to output energy according to the actual discharge current; read the second time record of the timer again, if the second time record does not exceed the duration of the pulse light, read the actual voltage of the pulse light source collected by the voltage sensor, combine the actual voltage with the equivalent power to calculate the actual discharge current, and control the pulse light source to output energy according to the actual discharge current, and so on; if the i-th time record exceeds the duration of the pulse light, send an instruction to end the output of the pulse light to the pulse light source, and the pulse light source responds to the instruction and ends the light emission.

[0091] The above embodiment mentioned that after the voltage is detected, the embodiment of the present application calculates the actual discharge current with the goal of achieving equivalent power, controls the pulse device to output energy according to the actual discharge current, and thus controls the pulse power supply to output energy at a stable equivalent power within the duration. Therefore, the embodiment of the present application also proposes a method for realizing the above control of the pulse light source to output energy at the actual discharge current:

[0092] Figure 6 is a circuit schematic diagram of the control circuit of the embodiment of the present application to execute the pulse energy output method, the control circuit is based on Figure 6 The circuit shown issues instructions and collects data.

[0093] Figure 6 As shown, the control circuit is connected to the energy storage capacitor group, which consists of six groups of capacitors C1, C2, C3, C4, C5, and C6. The control circuit pre-charges the energy storage capacitor group to a specified voltage, and the energy storage capacitor group provides instantaneous high-power electrical energy for the pulse light source when it emits light.

[0094] The control circuit is connected to a voltage sensor, and the voltage sensor is used to detect the voltage across the pulse light source.

[0095] The control circuit is connected to the current sensor, and the current sensor is connected to the inductor network circuit through a connection switching device, and the switching device is used to switch the circuit state of the inductor network circuit, and the inductor network circuit includes an inductor element L1 and a capacitor element C7. The connection switching device may include a switch.

[0096] based on Figure 6 The circuit schematic diagram shown in the figure includes the following steps to realize the control of the pulse light source to output energy with the actual discharge current:

[0097] S10531: Setting the actual discharge current as the current threshold.

[0098] After the actual discharge current is calculated, a current threshold is set to trigger the connection switching device to switch the current state of the inductor network circuit.

[0099] S10532: Obtain the real-time current of the inductor network circuit collected by the current sensor.

[0100] S10533: When the real-time current exceeds the current threshold, control the switching device to switch the circuit state of the inductor network circuit to disconnected.

[0101] S10534: When the real-time current is lower than the current threshold, control the switching device to switch the circuit state of the inductor network circuit to connection.

[0102] Through step S10533 and step S10534, if it is detected that the real-time current of the inductor network circuit exceeds the current threshold, the switching device switches the circuit state of the inductor network circuit to disconnection, so that the inductor network circuit is discharged and the current is reduced; if it is detected that the real-time current of the inductor network circuit is lower than the current threshold, the switching device switches the circuit state of the inductor network circuit to connection, so as to increase the current, thereby maintaining the current output by the inductor network circuit within the current threshold, that is, maintaining the current output by the inductor network circuit as the actual discharge current.

[0103] The pulse energy output method provided in the embodiment of the present application is based on the discovered discharge characteristic distribution of the pulse light source to obtain the equivalent power of the total energy that can be discharged and output by the pulse light source at the required power; then the energy outputted at the constant power is converted into the adjustment of the current, based on the way of adjusting the constant current of the pulse light source, a voltage sensor is added to the circuit of the control circuit to realize the function, the real-time voltage of the pulse light source is collected, and the actual discharge current that needs to be matched with the real-time current to achieve the equivalent power is reversely calculated, and then the current threshold of the switching device is set, based on the control circuit of the original control circuit, the purpose of controlling the pulse light source to output energy according to the actual discharge current can be achieved. The above method only needs to add a voltage sensor to the control circuit of the control circuit, and does not need to add other hardware, which saves costs, and the operation of modifying the current threshold of the switching device through the control circuit is simple, and the pulse light source is realized in a low-energy consumption manner to output energy at an equivalent power, so as to achieve a constant output light intensity.

[0104] Continue to refer Figure 2 Since the instantaneous power provided by the energy storage capacitor at the moment of light emission is too large, it is easy for the strong pulse light power to exceed the safety value. In view of this, when calculating the equivalent power, the calculated equivalent power should not exceed the safety value. Therefore, the execution of step S102 can be achieved by the following sub-steps:

[0105] S1021: Obtain a safe value of the required power under the function limitation corresponding to the user instruction.

[0106] The safety value can be obtained in the following way: collect data generated during the pulse light treatment of the specified tissue, such as the pigment metabolism of the specified tissue, skin temperature, whether the tissue has a state change, etc., analyze the data, and obtain the safety value.

[0107] S1022: Based on the required power, the discharge characteristic distribution of the pulse light source obtained in advance is brought into play, and the safety value is used as a constraint condition to calculate the equivalent power corresponding to the required power when the pulse light source discharges according to the duration.

[0108] Determine whether the equivalent power is lower than a safety value. If the equivalent power is lower than the safety value, control the pulse therapy device to output energy within the duration according to the equivalent power.

[0109] In one example of the present application, the effective value of power for treating specific symptoms can also be obtained. Based on the required power, the discharge characteristic distribution of the pulse light source obtained in advance is brought into play. With the effective value as a constraint, the equivalent power corresponding to the required power is calculated when the pulse light source discharges according to the duration.

[0110] It is determined whether the equivalent power is higher than the effective value. If the equivalent power is higher than the effective value, the pulse therapy device is controlled to output energy within the duration according to the equivalent power.
