Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a control method for a scoliosis correction device. Background Art

[0002] In recent years, the number of patients with scoliosis in my country has increased, and it has been listed as one of the five common diseases among adolescents. Scoliosis not only causes physical pain and harm to the patient, but also affects the patient's mental health due to changes in body posture. It is extremely harmful to the physical and mental health of the patient, especially adolescents, and cannot be ignored.

[0003] Due to the "dose-dependent" effect of orthoses, orthoses often need to be worn for a long time a day. Current orthoses are difficult to automatically adjust the orthotic force. When patients exercise (or even breathe), the cross-section of their chest cavity increases, which causes the orthotic force on the patients to change. As the orthotic force continues to change, the patients' adaptability to the orthosis will decrease, and they will refuse to wear it. Summary of the invention

[0004] The present application provides a control method for a scoliosis correction device to solve the technical problem that the correction force applied by the existing scoliosis correction device is difficult to maintain smooth.

[0005] The present application provides a control method for a scoliosis correction device, which includes an orthosis and multiple airbags. The multiple airbags are respectively arranged at positions on the orthosis that contact points on the user's spine to be corrected, so as to apply a correction force to the user. The control method includes: obtaining the correction force applied by the airbag to the user; identifying the user's exhalation time period and inhalation time period according to the correction force applied by the airbag to the user; pressurizing the airbag in the exhalation time period and depressurizing the airbag in the inhalation time period, so that the difference in the correction force applied to the user in the exhalation time period and the inhalation time period is less than a specified threshold.

[0006] In this scheme, the corrective force applied to the user is monitored in real time, and the user's exhalation and inhalation time periods are identified accordingly, so that the airbag pressure can be appropriately increased during exhalation and the pressure can be appropriately reduced during inhalation, thereby effectively reducing the sudden change of corrective force caused by respiratory movement, avoiding the discomfort caused to the user by the sudden increase or decrease of the corrective force, and significantly improving the user's comfort during the correction process. This method ensures that the corrective force fluctuations to the user remain within the specified threshold throughout the breathing cycle. This stable corrective force output helps the spine to be gradually corrected under the action of continuous and gentle force, avoiding the instability of the correction effect that may be caused by drastic changes in the corrective force, affecting the patient's adaptability to the orthosis, and reducing the discomfort during the correction process. Increase the user's treatment compliance, this method helps to extend the single treatment time and increase the frequency of treatment, thereby accelerating the correction process of scoliosis and promoting the patient's early recovery.

[0007] In a further embodiment of the present application, the control method also includes: obtaining the pressure on the user's back; determining the user's current posture based on the pressure on the back; and adjusting the air pressure in the corresponding airbag according to the user's current posture so that the difference between the corrective force applied to the patient and the preset corrective force is less than the preset value.

[0008] In this solution, by obtaining the pressure on the user's back in real time, the system can accurately determine the user's current posture, including but not limited to standing, sitting, bending, lateral bending, etc. This precise posture recognition provides a reliable basis for subsequent correction force adjustment. Based on the user's current posture, the system can automatically adjust the air pressure in the corresponding airbag to ensure that the correction force on the patient is always within an acceptable difference range with the preset correction force, that is, the preset value. This dynamic adjustment mechanism can more effectively cope with the force changes of the spine under different postures and improve the correction effect.

[0009] In a further embodiment of the present application, the scoliosis correction device includes a plurality of first pressure sensors, which are arranged on the correction device and are on the same horizontal line as the airbag; obtaining the pressure on the user's back includes: obtaining the pressure on the user's back through the first pressure sensors.

[0010] In this solution, the first pressure sensor located on the orthosis can be used to determine the current posture of the user by detecting the pressure on the back.

[0011] In a further embodiment of the present application, the scoliosis correction device includes a plurality of first pressure sensors; the first pressure sensors are arranged between the airbag and the correction device; obtaining the correction force applied by the airbag to the user includes: obtaining the correction force applied by the airbag to the user through the first pressure sensors.

[0012] In a further embodiment of the present application, the scoliosis correction device includes a plurality of second pressure sensors, which are arranged on the correction device and correspond in number to the airbags, and each second pressure sensor is on the same horizontal line as the corresponding airbag; obtaining the pressure on the user's back includes: obtaining the pressure on the user's back through the pressure sensor.

[0013] In a further embodiment of the present application, the scoliosis correction device includes multiple air pressure sensors, which are respectively arranged in each airbag and / or in the connecting pipeline between the airbag and the air pump; the method also includes: obtaining the air pressure in the airbag through the air pressure sensor; when the air pressure in the airbag exceeds the air pressure threshold, adjusting the air pressure in the corresponding airbag.

[0014] In a further scheme of the present application, identifying the exhalation time period and the inhalation time period of the user according to the corrective force applied by the airbag to the user includes: obtaining the average value of the corrective force applied by multiple airbags to the user; calculating the difference between the average value of the corrective force and the preset corrective force; when the difference is positive, determining that the user is in the exhalation time period, otherwise determining that the user is in the inhalation time period.

[0015] In a further embodiment of the present application, the scoliosis correction device also includes an air pump and a regulating valve. The air pump is controllably connected to each airbag through the regulating valve. The airbag is pressurized during the exhalation time period and the airbag is depressurized during the inhalation time period. The method includes: connecting the airbag and the air pump by controlling the regulating valve to pressurize the airbag; and connecting the airbag with the outside world by controlling the regulating valve to depressurize the airbag.

[0016] In this solution, the air pump serves as a pressure source and can provide a stable and adjustable air pressure output, while the regulating valve serves as a control element and can accurately control the connectivity between the airbag and the air pump or the outside world. By combining the air pump and the regulating valve, the system can achieve precise control of the air pressure in the airbag, ensuring that the airbag can be pressurized and depressurized according to a preset pressure curve during the exhalation and inhalation time periods. By real-time monitoring of the user's breathing cycle, the switching state of the regulating valve can be intelligently controlled to synchronize the pressurization and depressurization of the airbag with the user's breathing rhythm to form a breathing adaptation mechanism. The dynamic breathing adaptation mechanism helps to reduce the fluctuation of the orthopedic force caused by respiratory movement and improve the comfort and stability during the orthopedic process.

[0017] In a further embodiment of the present application, the scoliosis correction device further includes a flow limiting valve, which is connected to the airbag via a regulating valve; the method further includes: controlling the rate of airbag decompression via the flow limiting valve.

[0018] In this scheme, the introduction of the flow limiting valve enables the system to more precisely control the rate of the airbag during the pressure relief process. By adjusting the opening of the flow limiting valve, the rate of change of the air pressure in the airbag can be accurately controlled, avoiding the discomfort or weakening of the correction effect caused by too fast or too slow pressure relief. During the correction process, if the pressure relief rate of the airbag is too fast, it may cause a sudden impact on the user and affect the comfort. The role of the flow limiting valve is to slow down this pressure relief rate, making the pressure relief process of the airbag smoother and softer, thereby improving the comfort of the user.

[0019] In a further embodiment of the present application, the scoliosis correction device also includes a junction box, one end of which is connected to the airbag, and the other end is connected to the regulating valve via a quick connector; the method also includes: when disconnecting the airbag from the regulating valve, the airtightness of the inside of the airbag is maintained by the quick connector, so that the airbag corrects the user with a constant air pressure.

[0020] In this solution, by providing a junction box and a quick connector, the air pump, regulating valve and other structures can be completely detached from the orthosis when the user goes out, thereby reducing the user's load and facilitating the user's outdoor activities.

[0021] In a further scheme of the present application, the airbag is pressurized during the exhalation time period and the airbag is depressurized during the inhalation time period so that the difference in the orthopedic force to which the user is subjected during the exhalation time period and the inhalation time period is less than a specified threshold value, including: pressurizing the airbag during the exhalation time period, obtaining the orthopedic force to which the user is subjected during the pressurization process of the airbag, so that the difference between the orthopedic force to which the user is subjected during the pressurization process and the preset orthopedic force is less than a first threshold value, and the first threshold value is less than a specified threshold value; depressurizing the airbag during the inhalation time period, obtaining the orthopedic force to which the user is subjected during the depressurization process of the airbag, so that the difference between the orthopedic force to which the user is subjected during the depressurization process and the preset orthopedic force is less than the first threshold value.

[0022] In summary, the control method of the scoliosis correction device provided by the present application has at least the following beneficial effects:

[0023] By real-time monitoring of the corrective force applied to the user and identifying the user's exhalation and inhalation time periods, the airbag pressure can be appropriately increased during exhalation and reduced during inhalation, thereby effectively reducing the sudden change of corrective force caused by respiratory movement, avoiding the discomfort caused to the user by the sudden increase or decrease of the corrective force, and significantly improving the comfort during the correction process.

[0024] This method ensures that the correction force fluctuations applied to the user remain within the specified threshold throughout the breathing cycle. This stable correction force output helps the spine to be gradually corrected under the action of continuous and gentle force, avoiding the instability of the correction effect caused by drastic changes in the correction force, which affects the patient's adaptability to the orthosis. By reducing discomfort during the correction process, increasing the user's treatment compliance and improving the frequency of treatment, the correction process of scoliosis is accelerated and the treatment effect is guaranteed.

[0037] Please refer to Figure 1The present application provides a scoliosis correction device, which includes an orthosis 9 and a plurality of airbags 1. The plurality of airbags 1 are respectively arranged at positions on the orthosis 9 that contact the points of the user's spine to be corrected, so as to apply correction force to the user.

[0038] Specifically, at least three airbags 1 are generally provided, and they are provided according to the scoliosis of the user. Currently, scoliosis generally includes C-type scoliosis and S-type scoliosis. When the user has C-type scoliosis, three airbags 1 are provided, and they are distributed at the three vertices of the scoliosis according to the "three-point force" principle of spinal correction; when the user has S-type scoliosis, four airbags 1 are provided; each airbag 1 corresponds to a correction force application point, and each airbag 1 is located on the side of the user's trunk after the orthosis 9 is worn. In the subsequent embodiments, the correction of C-type scoliosis is described.

[0039] In a specific embodiment, the airbag 1 includes a first airbag 1, a second airbag 1 and a third airbag 1 which are arranged in sequence at a height interval. The first airbag 1 and the second airbag 1 are distributed on one side of the orthosis 9, and the third airbag 1 is distributed on the other side of the orthosis 9.

[0040] The orthosis 9 is used for the user to wear, and preferably a conventional Xeno orthosis 9 is used, which is made by scanning the user's body so that the airbag 1 on the orthosis 9 fits the body better to apply the orthotic force.

[0041] Furthermore, a plurality of pressure sensors are provided on the orthosis 9, specifically including a first pressure sensor and a second pressure sensor 2, wherein the second pressure sensor 2 is provided on the corresponding airbag 1, and is located between the airbag 1 and the orthosis 9, so that the orthotic force applied by the corresponding airbag 1 can be obtained through the second pressure sensor 2; the first pressure sensor is also provided on the orthosis 9, but is located on the back of the human body after the orthosis 9 is worn, and each first pressure sensor is provided corresponding to each airbag 1 and is approximately on the same horizontal line with the corresponding airbag 1 after the orthosis 9 is worn, so that the back pressure changes obtained by the first pressure sensor can be adjusted by the corresponding airbag 1.

[0042] It should be noted that the first pressure sensor is arranged in close contact with the airbag 1. Figure 1 It is difficult to reflect in the figure, so it is not shown in the figure.

[0043] In order to optimize the patient's usage experience, the pressure sensor generally adopts a thin film pressure sensor to improve the comfort of the patient when wearing the orthosis 9.

[0044] In a specific embodiment, in order to facilitate the control of the air pressure of the airbag 1 so as to keep the corrective force smooth, the scoliosis correction device also includes an air pump 5, a regulating valve 6, a flow limiting valve 8 and an air pressure sensor 7. The air pump 5, the airbag 1 and the flow limiting valve 8 are all connected to the regulating valve 6, wherein the regulating valve 6 can be controlled to connect the airbag 1 to the flow limiting valve 8 or to connect the airbag 1 to the air pump 5. When the airbag 1 is connected to the air pump 5, the airbag 1 can be charged by the air pump 5. The other end of the flow limiting valve 8 is used for air outlet. Therefore, when the airbag 1 is connected to the flow limiting valve 8, the airbag 1 can be deflated. The flow limiting valve 8 can control the rate of pressure relief of the airbag 1, thereby ensuring smooth deflation and avoiding excessive fluctuations in the corrective force.

[0045] In a specific embodiment, the scoliosis correction device also includes a junction box 3 and a control box 4. The control box 4 is electrically connected to a pressure sensor, a regulating valve 6, and an air pressure sensor 7. The control box 4 has a power supply, and then controls the pressure sensor, the regulating valve 6, and the air pressure sensor 7 while supplying power. The junction box 3 is arranged on the orthosis 9 and is provided with a quick connector 9. The regulating valve 6 can be quickly connected to the orthosis 9 through the quick connector 9. The control box 4 is also connected to the junction box 3 through the quick connector 9. At the same time, the junction box 3 also has a self-sealing function. When the user goes out, the air pump 5, the regulating valve 6, the control box 4 and other components can be removed through the quick connector 9, thereby reducing the weight worn by the user, thereby improving the user's adaptability.

[0046] Furthermore, the orthosis 9 should have built-in pipes and circuits, wherein the pipes are used to connect the junction box 3 and the airbag 1, so that the airbag 1 can be connected to the regulating valve 6 through the junction box 3, and the circuits are used to connect the pressure sensor and the control box 4 to transmit the pressure data that can be obtained by the pressure sensor to the control box 4.

[0047] In combination with the scoliosis correction device provided above, the present application specifically provides a control method for controlling the scoliosis correction device, please refer to Figure 2 , the control method comprises:

[0048] S100: obtaining the orthopedic force applied by the airbag 1 to the user;

[0049] The corrective force applied by the airbag 1 to the user can be obtained through the second pressure sensor 2 , where the corrective force is the pressure directly applied by the airbag 1 to the user.

[0050] S200: Identify the user's exhalation time period and inhalation time period according to the correction force applied by the airbag 1 to the user. Please refer to Figure 3 , specifically including the following steps:

[0051] S210: Obtaining an average value of the correction force applied by the multiple airbags 1 to the user;

[0052] Through the corresponding second pressure sensor 2 on each airbag 1, the correction force applied by each airbag 1 to the user can be obtained, and the average value of the current correction force can be calculated by combining the correction forces applied by multiple airbags 1;

[0053] S220: Calculate the difference between the average value of the orthopedic force and the preset orthopedic force;

[0054] The preset correction force needs to be set in advance by conducting medical examinations on the user to obtain the user's spinal condition, and then the preset correction force needs to be determined based on the doctor's guidance and patient feedback.

[0055] S230: When the difference is positive, it is determined that the user is in the exhalation time period, otherwise it is determined that the user is in the inhalation time period.

[0056] S300: In the exhalation time period, the airbag 1 is pressurized, and in the inhalation time period, the airbag 1 is depressurized, so that the difference in the correction force applied to the user during the exhalation time period and the inhalation time period is less than a specified threshold value. Please refer to Figure 4 , which includes the following two steps:

[0057] S310: pressurizing the airbag 1 during the exhalation time period, obtaining the orthopedic force applied to the user during the pressurization process of the airbag 1, so that the difference between the orthopedic force applied to the user during the pressurization process and the preset orthopedic force is less than a first threshold, and the first threshold is less than the specified threshold;

[0058] By controlling the regulating valve 6 to connect the airbag 1 and the air pump 5, the airbag 1 can be pressurized. The second pressure sensor 2 can directly obtain the magnitude of the corrective force currently applied to the patient. During the process of pressurizing the airbag 1, the difference between the corrective force and the preset corrective force can be monitored in real time. If the difference is less than the first threshold, the airbag 1 is pressurized normally. If the difference is greater than the first threshold, the airbag 1 can be depressurized or the pressurization can be stopped.

[0059] S320: depressurizing the airbag 1 during the inhalation period, obtaining the orthopedic force applied to the user during the depressurization process of the airbag 1, and making the difference between the orthopedic force applied to the user during the depressurization process and the preset orthopedic force less than a first threshold value;

[0060] The airbag 1 is connected to the outside world by controlling the regulating valve 6 to relieve pressure of the airbag 1. Similarly, if the correction force applied to the user and the preset correction force are less than the first threshold, the airbag 1 is kept depressurized normally. If they are greater than the first threshold, the airbag 1 stops depressurizing.

[0061] The present application releases the pressure of the airbag 1 during the inhalation period, and ensures that the difference between the orthopedic force on the user during the pressure relief period and the preset orthopedic force is less than the first threshold value, and pressurizes the airbag 1 during the exhalation period, and ensures that the difference between the orthopedic force on the user during the pressurization period and the preset orthopedic force is less than the first threshold value, so that the orthopedic force on the user during the pressurization period and the pressure relief period can be kept nearly constant, and even if the orthopedic force changes, the change will be smooth. In addition, since the first threshold value is less than the specified threshold value, it can be ensured that the difference between the orthopedic force on the user during the pressurization period and the pressure relief period is less than the specified threshold value, that is, the orthopedic force on the user during the exhalation period and the inhalation period is kept stable.

[0062] During pressure relief, the rate of pressure relief of the airbag 1 is controlled by the flow limiting valve 8. The specified threshold value can be preset and is also determined based on the user's long-term usage status. If the user's adaptability decreases during long-term wearing of the orthosis 9, the specified threshold value can be appropriately increased. When the user's scoliosis morphology improves, the specified threshold value can be appropriately lowered. The first threshold value is less than the specified threshold value to prevent the difference between the corrective force and the preset corrective force of the regulating valve 6 from exceeding the specified threshold value during the corresponding process.

[0063] In general, in the above scheme, the air pump 5, as a pressure source, can provide a stable and adjustable air pressure output, and the regulating valve 6, as a control element, can accurately control the connection state between the airbag 1 and the air pump 5 or the outside world. By combining the air pump 5 and the regulating valve 6, the system can realize accurate regulation of the air pressure in the airbag 1, ensuring that the airbag 1 can be pressurized and depressurized according to the preset pressure curve during the exhalation time period and the inhalation time period. By real-time monitoring of the user's breathing cycle, the switching state of the regulating valve 6 can be intelligently controlled so that the pressurization and depressurization of the airbag 1 are synchronized with the user's breathing rhythm to form a breathing adaptation mechanism. The dynamic breathing adaptation mechanism helps to reduce the orthopedic force fluctuations caused by respiratory movements and improve the comfort and stability during the orthopedic process. The introduction of the limiting valve 8 enables the system to more finely control the rate of the airbag 1 during the depressurization process. By adjusting the opening of the limiting valve 8, the rate of change of the air pressure in the airbag 1 can be accurately controlled, avoiding the discomfort or weakening of the orthopedic effect caused by too fast or too slow depressurization. During the correction process, if the pressure relief rate of the airbag 1 is too fast, it may cause a sudden impact on the user and affect the comfort. The function of the flow limiting valve 8 is to slow down the pressure relief rate, making the pressure relief process of the airbag 1 smoother and gentler, thereby improving the comfort of the user.

[0064] In further embodiments, please refer to Figure 5 , the control method further comprises the following steps:

[0065] S400: Obtaining the pressure on the back of the user;

[0066] The pressure on the user's back is obtained through the first pressure sensor. The first pressure sensor located on the orthosis 9 can be used to determine the user's current posture by detecting the pressure on the back. After the user wears the orthosis 9, the first pressure sensor is attached to the back of the human body, so the pressure on the user's back is obtained through the first pressure sensor.

[0067] S500: Determine the current posture of the user based on the pressure on the back;

[0068] Postures include but are not limited to: sitting, squatting, lying flat and lying on the side. When the patient's posture changes, the pressure on the back will change. Therefore, the current posture of the patient can be calculated by the pressure on the back.

[0069] S600: adjusting the air pressure in the corresponding airbag 1 according to the current posture of the user, so that the difference between the orthopedic force applied to the patient and the preset orthopedic force is less than the preset value;

[0070] By acquiring the pressure on the user's back in real time, the user's current posture can be accurately judged, including but not limited to standing, sitting, bending, scoliosis, etc. Accurate posture recognition provides a reliable basis for subsequent correction force adjustment. Based on the user's current posture, the system can automatically adjust the air pressure in the corresponding airbag 1 to ensure that the correction force applied to the patient is always within an acceptable difference range with the preset correction force, that is, the preset value. This dynamic adjustment mechanism can more effectively cope with the changes in spinal force under different postures and improve the correction effect.

[0071] In a further embodiment, the control method further comprises the following steps:

[0072] The air pressure in the airbag 1 is obtained through the air pressure sensor 7; when the air pressure in the airbag 1 exceeds the air pressure threshold, the air pressure in the corresponding airbag 1 is adjusted so that the air pressure value is lower than the air pressure threshold.

[0073] Specifically, by presetting the air pressure threshold, it can be ensured that the air pressure in the airbag 1 will not affect the shape change of the airbag 1, that is, the air pressure threshold must at least meet the requirement that the airbag 1 cannot produce plastic deformation. Of course, its air pressure must also meet the requirements of various pipelines connected to the airbag 1. A certain value must be reserved on this value to reduce the air pressure. When adjusting the corresponding air pressure in the airbag 1, the regulating valve 6 can be connected to the airbag 1 and the flow limiting valve 8, so that the gas in the airbag 1 slowly flows out from the flow limiting valve 8.

[0074] In a further embodiment, the control method further comprises the following steps:

[0075] When the airbag 1 is disconnected from the regulating valve 6, the airtightness of the interior of the airbag 1 is maintained by the quick connector 10, so that the airbag 1 can correct the user with a constant air pressure.

[0076] In this solution, by setting the junction box 3 and the quick connector 10, the air pump 5, the regulating valve 6 and other structures can be separated from the orthosis 9 as a whole when the user goes out, thereby reducing the user's load and facilitating the user's outdoor activities. Since the quick connector 10 can relatively maintain the internal airtightness of the airbag 1, the air pressure no longer changes after being separated from the air pump 5 and other equipment. At this time, the scoliosis orthosis device is passively corrected, which improves the patient's compliance by sacrificing a certain correction efficiency in exchange for a lighter weight and a more private wearing experience.

[0077] In summary, this method monitors the orthopedic force applied to the user in real time, and identifies the user's exhalation and inhalation time periods accordingly, so that the pressure of the airbag 1 can be appropriately increased during exhalation, and the pressure can be appropriately reduced during inhalation, thereby effectively reducing the sudden change of orthopedic force caused by respiratory movement, avoiding the discomfort caused to the user by the sudden increase or decrease of the orthopedic force, and significantly improving the comfort during the orthopedic process. When the user's posture changes, the current posture is determined by obtaining the pressure on the user's back, and then the air pressure in the corresponding airbag 1 can be adjusted according to the posture, so that the orthopedic force on each part of the patient is in a dynamic balance. When the patient needs to reduce the load when going out, the air pump 5 and other large-mass structures can also be removed to further optimize the user's experience.

[0078] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
