Description

Technical Field

[0001] This invention relates to the field of medical aesthetic equipment technology, and in particular to an integrated intelligent nursing device and control method based on dynamic negative pressure elastic feedback. Background Technology

[0002] Decreased skin elasticity is a major characteristic of aging. Techniques that quantify skin elasticity by using vacuum negative pressure to adsorb skin and measuring its resilience, as well as physical therapies that use microcurrents and low-frequency radiofrequency for skin lifting and tightening, are widely used.

[0003] Currently, there have been attempts to integrate the two functions mentioned above into a single device. However, existing technologies have fundamental flaws in their structure and control logic: 1. Nursing and testing are performed sequentially, resulting in frequent interruptions. Traditional integrated devices use a time-sharing switching mode, which means that energy output is paused during nursing intervals to perform a dedicated flexible test, and nursing is resumed only after the test is completed. This leads to a discontinuous nursing process, affecting the user experience. More importantly, this intermittent testing loses the opportunity to obtain continuous flexible feedback throughout the entire nursing process.

[0004] 2. The inability to achieve synergistic effects throughout the entire treatment process using negative pressure elevation. Negative pressure causes localized skin elevation, improving tissue density and electrical conductivity, which is beneficial for electrical energy coupling. However, in serial mode, the skin is only in an elevated state for a brief moment during detection, remaining flat for the majority of the treatment time. When the operator moves the probe across the face, only the skin at the detection point is occasionally elevated for treatment, while the remaining large areas receive energy in a non-elevated state, making it impossible to achieve synergistic effects across the entire area. This is the biggest technical blind spot in the current design.

[0005] 3. Reliance on manual experience and lack of real-time adaptive adjustment. Because detection and care are separated in time, even if detection is performed, the results are only used for passive display and cannot dynamically respond to the real-time skin condition during the current care process or adjust parameters. The care endpoint is entirely based on the operator's subjective judgment, often leading to over- or under-care.

[0006] Therefore, there is an urgent need for a device that can eliminate the contradiction between nursing and testing, and achieve uninterrupted lifting care and intelligent feedback control throughout the entire process, in order to meet the needs of high-quality standardized anti-aging care. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned shortcomings and defects of the prior art by providing an integrated intelligent nursing device and control method based on dynamic negative pressure elastic feedback, thereby solving the above problems.

[0008] The technical problem solved by this invention can be achieved by the following technical solutions: An integrated intelligent nursing device based on dynamic negative pressure elastic feedback includes a nursing probe. The front end of the nursing probe is provided with an electrode device and a negative pressure suction port. The negative pressure suction port is connected to a negative pressure generating device disposed inside the nursing probe. The nursing probe is also provided with a displacement detection device for detecting changes in skin displacement. The electrode device, negative pressure generating device, displacement detection device and control device are connected.

[0009] In a preferred embodiment of the present invention, the negative pressure suction port is disposed at the middle of the front end of the nursing probe, and the electrode device is circumferentially distributed around the outer periphery of the negative pressure suction port.

[0010] In a preferred embodiment of the present invention, the electrode device includes an electrode sheet and a micro-current radio frequency generating module connected to the electrode sheet. The electrode sheet includes annular electrodes or symmetrically distributed arc-shaped electrodes circumferentially distributed around the negative pressure suction port. The micro-current radio frequency generating module is connected to the control device.

[0011] In a preferred embodiment of the present invention, the negative pressure generating device includes a miniature vacuum pump, which is connected to the negative pressure suction port via a negative pressure pipe. An electromagnetic valve assembly is provided on the negative pressure pipe, and the miniature vacuum pump, the electromagnetic valve assembly, and the control device are connected.

[0012] In a preferred embodiment of the present invention, the displacement detection device includes a laser displacement sensor disposed inside the negative pressure suction port.

[0013] A control method for an integrated intelligent nursing device based on dynamic negative pressure elastic feedback as described in any of the above technical solutions includes the following steps: S1. Initial elasticity detection to obtain the initial elasticity value E0, and set the initial care parameters accordingly. The initial elasticity value E0 = (H0-L0) / T0, where H0 is the height of the skin being sucked up under the initial negative pressure, L0 is the height of the skin after the negative pressure is released, and T0 is the rebound time of the skin from H0 to L0. H0 and L0 are measured by the displacement detection device, and T0 is obtained by the control device based on the time difference between H0 and L0 measured by the displacement detection device. S2. Start nursing care. The control device controls the negative pressure generating device to output a periodic negative pressure pulse train of a preset frequency. At the same time, the control device controls the electrode device to output energy synchronously, so that the skin covered by the end face of the nursing probe receives synergistic care in a dynamically raised and enhanced state. S3. Obtain the skin elasticity improvement status. During the nursing process, a complete negative pressure suction and release cycle is captured from the negative pressure pulse train. The skin rebound characteristics after the negative pressure is released in the cycle are detected, and the current elasticity value E1 is calculated. The current elasticity value E1 = (H1-L1) / T1, where H1 is the height of the skin being sucked up in the cycle, L1 is the height of the skin after the negative pressure is released, and T1 is the rebound time of the skin from H1 to L1. H1 and L1 are measured by the displacement detection device, and T1 is obtained by the control device based on the time difference between H1 and L1 measured by the displacement detection device. The elasticity improvement rate ΔE1 = (E1-E0) / E0 is calculated. S4. Assess skin elasticity index If ΔE1 is lower than the first threshold, increase the intensity of care and return to step S3. If ΔE1 is between the first threshold and the second threshold, maintain the current parameters and return to step S3. If ΔE1 exceeds the second threshold, reduce the intensity of care and return to step S3. If E1 reaches the preset termination condition value a or |E1-E0| changes in elasticity value for two consecutive times less than b, where b is the preset change range value, then the nursing care is deemed adequate, and the control device immediately shuts off all outputs.

[0014] In a preferred embodiment of the present invention, in step S4, the first threshold is 15%, the second threshold is 30%, the preset termination condition value a is the ideal elasticity value of users in this age group, that is, the average value of skin elasticity values ​​based on big data statistics of each age group, and b is 2%.

[0015] In a preferred embodiment of the present invention, in step S4, The increased nursing intensity is achieved by: setting the microcurrent rated power to Pe, the radio frequency rated power to Pr, and the pulse state to continuous wave. The current parameters are maintained as follows: rated power of microcurrent is 0.8Pe, rated power of radio frequency is 0.8Pr, and pulse state is pulse wave; The reduced nursing intensity is achieved by setting the microcurrent rated power to 0.5Pe, the radio frequency power rated to 0.5Pr, and the pulse state to a scanning wave.

[0016] In a preferred embodiment of the present invention, Pe = 1.2W and Pr = 4W.

[0017] In a preferred embodiment of the present invention, in S4, the control device immediately shuts down all outputs and then notifies the patient that the care is complete via a prompt tone.

[0018] Due to the adoption of the above technical solution, the present invention has the following beneficial effects: This invention constructs the nursing process on a continuous, periodic dynamic negative pressure pulse cycle, causing the skin to repeatedly experience a dynamic lifting state of "lifting-rebounding" for most of the time. During this period, microcurrent and radiofrequency energy are applied simultaneously, achieving a superposition of physical lifting and energy care effects. At the same time, the system selectively captures specific cycles from the dynamic pulse train for elasticity analysis, adjusts parameters in real time without interrupting the care, and intelligently determines the end point of the care.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] See Figures 1 to 4 As shown, the integrated intelligent nursing device based on dynamic negative pressure elastic feedback includes a nursing probe 100 and a control device 200. The front end of the nursing probe 100 is provided with an electrode device 300 and a negative pressure suction port 400. The negative pressure suction port 400 is connected to a negative pressure generating device 500 disposed inside the nursing probe 100. The nursing probe 100 is also provided with a displacement detection device 600 for detecting changes in skin displacement. The electrode device 300, the negative pressure generating device 500, the displacement detection device 600 and the control device 200 are connected.

[0030] In this embodiment, the end face 110 of the nursing probe 100 is elliptical or circular, suitable for facial operation. The negative pressure suction port 400 is located at the center of the front end of the nursing probe 100, and the electrode device 300 is circumferentially distributed around the outer periphery of the negative pressure suction port 400. Preferably, the electrode device 300 includes an electrode sheet 310 and a microcurrent radio frequency generation module 320 connected to the electrode sheet 310. The electrode sheet 310 includes annular electrodes or symmetrically distributed arc-shaped electrodes circumferentially distributed around the outer periphery of the negative pressure suction port 400. The microcurrent radio frequency generation module 320 is connected to the control device 200. The circumferential layout of the electrode sheet 310 ensures that when the skin bulges under negative pressure, the bulging spherical surface and its sloping area are effectively covered by the electrode sheet 310, forming a uniform energy field. The microcurrent radio frequency generation module 320 includes an adjustable current source and a radio frequency oscillator, capable of outputting a microcurrent with an adjustable frequency of 0.1-500Hz and intensity, as well as a low-frequency radio frequency with a frequency range of 50kHz to 200kHz, and supports various waveform modulations. The microcurrent radio frequency generation module 320 is connected to the electrode plate 310 to generate microcurrent and low-frequency radio frequency energy.

[0031] In this embodiment, the negative pressure generating device 500 includes a miniature vacuum pump 510, which is connected to the negative pressure suction port 400 via a negative pressure tube 520. The negative pressure tube 520 is equipped with a solenoid valve assembly 530 and a pressure sensor 540. The miniature vacuum pump 510, the solenoid valve assembly 530, and the control device 200 are connected. The miniature vacuum pump 510 generates a negative pressure source, and the solenoid valve assembly 530 rapidly switches between inhalation, holding, and release states to form pulses. This causes the skin to repeatedly bulge and rebound under the pulse action, and accurately detects the skin deformation and rebound characteristics in a specific pulse cycle when elasticity testing is required. The pressure sensor 540 detects the negative pressure data. Preferably, the frequency range of the periodic negative pressure pulse train is 0.5Hz to 5Hz. This frequency range can create a significant dynamic lifting and massage effect while allowing sufficient time for the skin to fully rebound after release, ensuring the reliability of subsequent elasticity calculation data.

[0032] In this embodiment, the displacement detection device 600 includes a laser displacement sensor, which is disposed inside the negative pressure suction port 400. The laser displacement sensor is used to non-contactly measure the height at which the skin is sucked into the suction port.

[0033] The control device 200 is an embedded controller based on ARM or FPGA, working in conjunction with the operating host 700 with a display 710, as is common knowledge in the art. The operating host 700 is equipped with a clip 720 for fixing the nursing probe 100, and the nursing probe 100 is connected to the operating host 700 via a cable 730. When capturing a complete negative pressure suction-discharge cycle to calculate the elasticity value, the control device 200 can choose to briefly pause the energy output of the microcurrent radio frequency generator module 320 during the negative pressure release phase of the capture cycle to prevent residual electrical signals from interfering with the rebound detection. The pause time is usually less than 0.5 seconds and occurs only within a single pulse cycle, without affecting the continuity of the overall care. The preset detection time can be: triggered once every preset duration (e.g., 30 seconds); or triggered once every preset number of negative pressure pulse cycles (e.g., every 60 pulse cycles). The pulse train around the detection time continues normally, only "borrowing" one cycle for analysis.

[0034] Combination Figures 1 to 5 As shown, a control method for an integrated intelligent nursing device based on dynamic negative pressure elastic feedback includes the following steps: S1. Initial elasticity detection is performed to obtain the initial elasticity value E0, and the initial care parameters are set accordingly. The initial elasticity value E0 = (H0 - L0) / T0, where H0 is the height of the skin being lifted under the initial negative pressure, L0 is the height of the skin after the negative pressure is released, and T0 is the rebound time of the skin from H0 to L0. H0 and L0 are measured by the displacement detection device, and T0 is obtained by the control device based on the time difference between H0 and L0 measured by the displacement detection device. For example, firstly, the operator places the probe end face against the area to be cared for on the face of the patient; the control device 200 first performs an initial elasticity detection to establish a baseline. The method is as follows: In the microcurrent radio frequency off state, a short-term negative pressure (e.g. -25kPa) is generated at the negative pressure suction port 400 by the micro vacuum pump 510 and the solenoid valve group 530. After the displacement detection device 600 monitors the skin suction height and reaches the set value (e.g. 1.5mm), the negative pressure is quickly released, the time for the skin to rebound to the original position is recorded, and the initial elasticity value E0 is obtained and stored according to the above formula. S2. Start nursing care. Control device 200 controls negative pressure generator 500 to output a periodic negative pressure pulse train of preset frequency. At the same time, control device 200 controls electrode device 300 to output energy synchronously, so that the skin covered by the end face of nursing probe 100 receives synergistic care in a dynamically raised and enhanced state. S3. Obtain the skin elasticity improvement status. During the treatment, a complete negative pressure suction and release cycle is captured from the negative pressure pulse train. The skin rebound characteristics after the negative pressure is released in the cycle are detected, and the current elasticity value E1 is calculated. The current elasticity value E1 = (H1-L1) / T1, where H1 is the height of the skin being sucked up in the cycle, L1 is the height of the skin after the negative pressure is released, and T1 is the rebound time of the skin from H1 to L1. H1 and L1 are measured by the displacement detection device 600, and T1 is obtained by the control device 200 based on the time difference between H1 and L1 measured by the displacement detection device 600. The elasticity improvement rate ΔE1 = (E1-E0) / E0 is calculated. S4. Assess skin elasticity index If ΔE1 is lower than the first threshold, increase the intensity of care and return to step S3. If ΔE1 is between the first threshold and the second threshold, maintain the current parameters and return to step S3. If ΔE1 exceeds the second threshold, reduce the intensity of care and return to step S3. If E1 reaches the preset termination condition value a or |E1-E0| changes in elasticity value for two consecutive times less than b, where b is the preset change range value, then the nursing care is determined to be in place, and the control device 200 immediately shuts off all outputs.

[0035] Preferably, in S4, the first threshold is 15%, the second threshold is 30%, the preset termination condition value a is the ideal elasticity value for users in this age group, that is, the average of skin elasticity values ​​based on big data statistics for each age group, and b is 2%. Increasing the care intensity is: microcurrent rated power is Pe, radiofrequency power rated is Pr, and the pulse state is continuous wave; maintaining the current parameters is: microcurrent rated power is 0.8Pe, radiofrequency power rated is 0.8Pr, and the pulse state is pulse wave; decreasing the care intensity is: microcurrent rated power is 0.5Pe, radiofrequency power rated is 0.5Pr, and the pulse state is scanning wave. Pe = 1.2W, Pr = 4W. The control device then shuts down all outputs and announces the completion of the care through a prompt tone.

[0036] Specifically, the control device 200 integrates the aforementioned pulse timing generation logic, elasticity calculation algorithm, parameter tuning mapping table, and nursing endpoint determination program. The preset parameter tuning strategy includes a lookup table or function model reflecting the mapping relationship between skin elasticity values, elasticity change rate, microcurrent power, radio frequency power, and waveform patterns; waveform patterns include continuous waves, pulse waves, scanning waves, and their combinations. See Table 1 below for reference. Table 1 ; When the nursing care officially begins, the control device 200 calls a set of appropriate initial parameters from the mapping table according to E0, such as: microcurrent power Pe=1.2W, radio frequency power Pr=4W, and waveform mode is "alternating pulse wave and continuous wave".

[0037] The pre-stored skin elasticity value is the height H that the skin is lifted up under negative pressure. n Subtract the height L after releasing the negative pressure n The difference between the rebound time T and the rebound time T n The ratio, and the average value of skin elasticity values ​​based on big data statistics for each age group, i.e., E_target={(H1-L1) / T1+(H2-L2) / T2+……(H n -L n ) / T n The elasticity improvement rate is ΔE1 = (E1 - E0) / E0, where E0 is the initial skin elasticity value, and E1 is the current skin elasticity value, which is the ratio of the difference between the height H of the skin being lifted under negative pressure at different times and the height L after the release of negative pressure, to the rebound time T, i.e., E0 or E1 = (HL) / T. Continuous wave is the simultaneous superposition of microcurrent and radio frequency output, pulse wave is the intermittent superposition of microcurrent and radio frequency output, and scanning wave is the alternating output of microcurrent and radio frequency. According to the mapping relationship, when the conditions ΔE1 ≤ 15% and E1 ≤ E_target are met, the microcurrent output power Pe is the rated power, the radio frequency output power Pr is the rated power, and the waveform combination is a continuous wave. When the conditions 15% < ΔE1 < 30% and E1 ≤ E_target are met, the microcurrent power Pe is reduced to 80%, the radio frequency power Pr is reduced to 80%, and the waveform combination is a continuous wave for 5s and a pulse wave for 25s in a cycle. When the conditions ΔE1≥30% and E1≤E_target are met, the microcurrent power Pe is reduced to 50%, the radio frequency power Pr is reduced to 50%, and the waveform combination is a continuous wave of 5s, a pulse wave of 10s, and a scanning wave of 15s, which are cycled.

[0038] Furthermore, the preset endpoint conditions include: the current elasticity value E1 reaches the preset ideal elasticity target value E_target, or the change in elasticity value obtained from two consecutive measurements is less than a preset convergence threshold, indicating that the improvement of skin elasticity has entered a plateau phase. That is, when E1 > E_target or the difference between two consecutive ΔE1 values ​​is less than 2%, i.e., |ΔE1| < 2%, the endpoint is defined as follows: n -ΔE1 n+1 Nursing care was terminated when the percentage was less than 2%.

[0039] Unlike existing technologies, the entire nursing process of this invention eliminates the silent pure care period and the interrupted detection period. The control device 200 immediately instructs the negative pressure generating device 500 to continuously generate a series of periodic negative pressure pulses at a fixed frequency, for example, 2Hz (i.e., one complete cycle every 0.5 seconds). Each pulse includes: inhalation (e.g., 0.2 seconds, causing the skin to bulge to approximately 1.5mm), holding (e.g., 0.05 seconds), and rapid release (e.g., 0.25 seconds, allowing the skin to rebound). This series of pulses forms a dynamic lifting rhythm of "inhalation-bulge-release-rebound." Simultaneously, the microcurrent radiofrequency generating module 320 is activated, continuously or alternately outputting energy through the electrode pads 310 according to initial parameters. For the vast majority of the time, the holding of the skin bulge and the energy injection overlap in time, achieving a synergistic effect at the physiological level. Macroscopically, the user's skin is repeatedly lifted by a rhythmic force, accompanied by warmth and microneedle-like sensations, resulting in a strong and continuous nursing experience.

[0040] To achieve intelligent feedback, the built-in detection timer of the control device 200 is set to initiate elastic sampling every 30 seconds. When a certain 30-second interval arrives, the control device 200 does not stop the entire dynamic process, but instead "marks" the next complete pulse cycle in the program. Specifically, during the "release" phase of this marked cycle, the control device 200 can momentarily pause the radio frequency and microcurrent output (approximately 0.3 seconds, to avoid interfering with the sensor signal) and simultaneously acquire displacement or pressure data to calculate the skin rebound time of that pulse, thereby obtaining the current elasticity value E1. Because the pause is embedded within the pulse cycle and is extremely short, enveloped by continuous lifting pulses, the patient is completely unaware of any interruption.

[0041] The mechanism for achieving full-area coverage in this invention: During the treatment, the operator naturally and slowly moves the probe along the facial contours and skin texture. Because the negative pressure pulse from the probe is continuous, as it moves from one location to an adjacent location, the newly entered skin within the probe's coverage area is immediately incorporated into this "pulse absorption and release - energy synchronization" cycle. Therefore, all skin tissue along the entire movement path receives synergistic care from microcurrents and radiofrequency in a heightened, enhanced state, achieving truly comprehensive, non-discriminatory enhancement. This is something that existing devices that can only create a short-term heightening effect at a fixed point cannot achieve.

[0042] Dynamic optimization of the mapping strategy of this invention: The parameter tuning mapping table not only contains static elasticity-parameter correspondences but can also be dynamically adjusted based on the elasticity boost rate. For example, if two consecutive tests detect a slowdown in the elasticity boost rate, even if convergence has not yet occurred, the control module can automatically fine-tune the waveform duty cycle to change the thermal action mode and break the plateau. These strategies can all be iterated through firmware upgrades.

[0043] This invention constructs the nursing process on a continuous, periodic dynamic negative pressure pulse cycle, causing the skin to repeatedly experience a dynamic lifting state of "lifting-rebounding" for most of the time. During this period, microcurrent and radiofrequency energy are applied simultaneously, achieving a superposition of physical lifting and energy care effects. At the same time, the system selectively captures specific cycles from the dynamic pulse train for elasticity analysis, adjusts parameters in real time without interrupting the care, and intelligently determines the end point of the care.

The current elasticity value E1 = (H1-L1) / T1, where H1 is the height of the skin being sucked up in the cycle, L1 is the height of the skin after the negative pressure is released, and T1 is the rebound time of the skin from H1 to L1. H1 and L1 are measured by the displacement detection device, and T1 is obtained by the control device based on the time difference between H1 and L1 measured by the displacement detection device. The elasticity improvement rate ΔE1 = (E1-E0) / E0 is calculated. S4. Assess skin elasticity index If ΔE1 is lower than the first threshold, increase the intensity of care and return to step S3. If ΔE1 is between the first threshold and the second threshold, maintain the current parameters and return to step S3. If ΔE1 exceeds the second threshold, reduce the intensity of care and return to step S3. If E1 reaches the preset termination condition value a or |E1-E0| changes in elasticity value for two consecutive times less than b, where b is the preset change range value, then the nursing care is deemed to be in place, and the control device immediately shuts off all outputs.
