Description

Technical Field

[0001] The present invention relates to a physiotherapy device, and more specifically, to a physiotherapy device based on air pressure and its control method. Background Art

[0002] An air pressure physiotherapy instrument (also known as a pneumatic physiotherapy instrument or a cyclic pressure physiotherapy instrument) is a medical rehabilitation device that simulates massage effects through controllable air pressure. It controls multi-chamber airbags wrapped around the limbs or torso through a main unit to achieve a regular inflation and deflation cycle, thereby forming a gradient pressure that progresses from the distal end to the proximal end of the limb to promote blood and lymphatic fluid return. This device is widely used in postoperative rehabilitation, sports injury recovery, and physiotherapy for blood circulation disorders, and has significant effects especially on patients who are bedridden for a long time or have limited mobility.

[0003] In order to adapt to the human physiological structure, existing long air pressure physiotherapy instruments usually include the joint activity area in the physiotherapy range, and their airbag design adopts a preset bending angle to match the conventional joint shape. However, in clinical applications, it is found that such a design has the following limitations.

[0004] Insufficient adaptability: The preset bending angle is designed based on the joint mobility of the general population. For special groups with joint stiffness and limited mobility (such as patients with arthritis, postoperative immobilization, or congenital deformities), the preset angle may far exceed their actual physiological bending arc; Contradiction between therapeutic effect and comfort: When the preset angle is greater than the actual bending ability of the patient's joint, excessive stretching or local high pressure will occur in the airbag during the inflation process, resulting in pain and discomfort. If the discomfort is relieved by reducing the air pressure, it is difficult to reach the effective physiotherapy pressure threshold, forming a dilemma of "insufficient therapeutic effect when discomfort is reduced, and poor tolerance when the therapeutic effect is ensured". Summary of the Invention

[0005] Therefore, in order to solve the above deficiencies, the present invention provides a physiotherapy device and its control method herein. The physiotherapy device is an air pressure physiotherapy instrument, and by installing a bending degree maintaining device at the bending part of the air pressure physiotherapy module, the preset bending degree of the bending part of the airbag is changed and maintained to meet the use of special groups, reduce the discomfort of special groups during use, and also be able to perform physiotherapy without reducing the air pressure.

[0006] On the one hand, the present invention provides a physiotherapy device, including an air pressure physiotherapy module and a control module. The control module is used to control the air pressure of the air pressure physiotherapy module. The air pressure physiotherapy module acts on the limb of the user. The air pressure physiotherapy module has at least one joint bending part, and a bending degree maintaining device is installed on one or both sides of the joint bending part; The bending degree maintaining device includes an included angle adjusting rod, an included angle fixing rod, and an included angle maintaining member. The included angle adjusting rod is fixed to one end of the bending part, and the included angle fixing rod is fixed to the other end of the bending part. The included angle adjusting rod is provided with an included angle adjusting part. The end of the included angle fixing rod is rotatably connected to the included angle adjusting part. An included angle fixing hole is formed in the included angle fixing rod, and a plurality of circumferentially arranged angle adjusting holes are formed in the included angle adjusting part with the rotation center of the included angle fixing rod as the center of the circle. The included angle maintaining member passes through the included angle fixing hole and is inserted into one of the angle adjusting holes.

[0007] Optionally, a mounting shaft for rotatably mounting the included angle fixing rod is fixedly provided on the included angle adjusting part, and a plurality of circumferentially arranged elastic positioning members are provided at the front part of the mounting shaft.

[0008] Optionally, the included angle adjusting rod and / or the included angle fixing rod is provided with a telescopic sleeve. The telescopic sleeve is provided with a plurality of telescopic adjusting holes arranged along the length direction of the telescopic sleeve, and a positioning member matching the telescopic adjusting holes is provided on the included angle adjusting rod and / or the included angle fixing rod.

[0009] Optionally, the distance from the elastic positioning member to the included angle adjusting part is not less than the thickness of the telescopic sleeve mounted on the included angle fixing rod.

[0010] Optionally, a storage hole for placing the included angle maintaining member is formed in the included angle adjusting part or the included angle adjusting rod.

[0011] Optionally, the included angle adjusting rod and the included angle fixing rod are fixedly mounted on the joint bending part through a strip pocket or a fixing member; the strip pocket is formed in the air pressure physiotherapy module. The fixing member includes a lace and a connecting block fixed to the lace. The connecting block has a mounting through hole adapted to the included angle adjusting rod or the included angle fixing rod.

[0012] Optionally, it further includes a heart rate monitoring module and a timing module in communication with the control module.

[0013] On the other hand, the present invention provides a control method for a physiotherapy device, including the following steps: S100. Obtain the body parameters of the user. The body parameters at least include gender and age.

[0014] S200. Determine a threshold group and a pressure adjustment value △P according to the body parameters.

[0015] The threshold group includes a heart rate threshold HR adapted to age and gender 标准 , an extreme heart rate threshold HR 极限 , a standard air pressure value P 标准 and a time value; the time value includes a first time value T1 (such as 30 seconds), a second time value T 2 (such as 60 seconds) and a third time value T 3 (such as 90 seconds), where T 1 < T 2 < T 3 . The heart rate threshold, the maximum heart rate threshold, the standard air pressure value, and the time value are preset in advance according to parameters such as the age and gender of the user. Because the heart rates of children, young people, and the elderly are different under the same conditions and also vary according to gender, and can also be preset in advance according to the type of user (such as an athlete). Among them, the standard air pressure value P 标准 is a range value because during physical therapy, physical therapy is achieved through changes in pressure. The air pressure adjustment value △P refers to the degree of adjustment when adjusting the air pressure and is preset in advance. The maximum heart rate threshold HR 极限 is the maximum limit value. After exceeding this value, it is necessary to immediately stop physical therapy and reset the air pressure to zero.

[0016] The threshold group is a preset value and is stored in the database of the control module in a modular form according to age stages and gender types. When in use, just select the corresponding module, and the threshold group will be automatically formed.

[0017] S300. Start the pneumatic physical therapy device to perform physical therapy on the user according to the start signal, and adjust the pressure of the air pressure physical therapy module according to the control logic.

[0018] Exemplarily, the control logic is as follows: S301. Monitor the real-time heart rate HR 实时 of the user and the real-time pressure P 实时 of the air pressure physical therapy module; S302. When the real-time heart rate HR 实时 ≤ the heart rate threshold HR 标准 , then maintain the standard air pressure value P 标准 ; S303. When the real-time heart rate HR 实时 > the heart rate threshold HR 标准 , start the timer and execute the pressure adjustment logic, otherwise reset the timer.

[0019] Exemplarily, the pressure adjustment logic includes: S3031. When the timing duration T of the timer ≥ the first time value T 1 , then reduce the pressure of the air pressure physical therapy module according to the air pressure adjustment value.

[0020] S3032. When the real-time heart rate HR 实时 does not decrease or does not decrease to the heart rate threshold HR within the second time value T 2 ​标准 When it is time, the air pressure of the air pressure physiotherapy module is reduced by the air pressure adjustment value set by a multiple.

[0021] S3033. When the real-time heart rate HR 实时 ≥ the limit heart rate threshold HR 极限 or within the third time value T 3 the real-time heart rate HR 实时 does not decrease or does not decrease to the heart rate threshold HR 标准 , then the air pressure returns to zero and an alarm is issued.

[0022] The present invention has the following advantages: The physiotherapy device of the present invention realizes the adjustment and maintenance of the bending angle of the bending part by installing a bending angle maintaining device at the joint bending part, so as to reduce the discomfort of special populations (such as arthritis, postoperative immobilization or congenital deformity patients) during physiotherapy due to the mismatch between the joint bending angle and the preset radian.

[0023] The adjustment and maintaining device realizes the adjustment of the included angle through the included angle adjustment rod and the included angle fixing rod fixed to the bending part, and fixes the included angle by using the included angle maintaining part. The structure is simple and the operation is convenient; an included angle adjustment part is arranged on the included angle adjustment rod. The included angle adjustment part has several circumferentially arranged angle adjustment holes, and the several angle adjustment holes are arranged with the rotation center of the included angle fixing rod as the center of the circle, which can realize the adjustment of multiple angles of the included angle adjustment rod and the included angle fixing rod to adapt to different populations. At the same time, the included angle adjustment part is located at the end of the included angle adjustment rod. While realizing the rotational connection between the included angle adjustment rod and the included angle fixing rod, the length of the included angle adjustment rod is effectively controlled, and the included angle adjustment part is semi-circular, and there is a hollow design in the middle of the semi-circle. This semi-circular design provides a layout space for several angle adjustment holes, and the hollow design reduces the weight and material consumption, and is convenient for the staff to take and store.

[0024] At the same time, a mounting shaft is fixedly arranged on the included angle adjustment part, which can realize the rotational mounting of the included angle fixing rod. By fixedly arranging the mounting shaft, the risk of parts falling is reduced, and the installation process of parts is also reduced. And an elastic positioning part (similar to a ball head set screw) is arranged on the mounting shaft, which reduces the risk of falling off after installation and is also convenient for installing and disassembling the included angle fixing rod. At the same time, the distance from the elastic positioning part to the included angle adjustment part is not less than the thickness of the telescopic sleeve installed on the included angle fixing rod. This design can realize that when the adjustment and maintaining device is stored, the included angle adjustment rod and the included angle fixing rod coincide (as Figure 6 and Figure 7 shown).

[0025] At the same time, in order to improve the installation stability of the angle adjustment rod or the angle fixing rod, the angle adjustment rod and the angle fixing rod are provided with a telescopic sleeve. By changing the length of the angle adjustment rod or the angle fixing rod, the stability of the angle can be improved, and it is also convenient to fix it to adapt to various angle changes; because the smaller the angle, the greater the force required to maintain the angle during the inflation process. If the angle is fixed, the more points of force or the longer the length of the angle adjustment rod or the angle fixing rod are fixed, the easier it is to provide the holding force. After changing the length, more fixing points or farther fixing points can be provided to provide better holding force and reduce the risk of falling off. At the same time, by providing a number of telescopic adjustment holes arranged along the length direction of the telescopic sleeve on the telescopic sleeve, the telescopic length can be adjusted to provide better holding force. At the same time, it can also adapt to the installation of the angle adjustment rod or the angle fixing rod in different situations. For example, in the bending part of the ankle, the space is limited, so the angle adjustment rod or the angle fixing rod is not easy to be too long, which will lead to inconvenience in installation.

[0026] At the same time, a storage hole for placing an angle retaining member is provided on the angle adjustment portion or the angle adjustment rod, which can avoid the loss of parts and improve the durability of the equipment.

[0027] In order to fix the angle adjustment rod or the angle fixing rod, the angle adjustment rod or the angle fixing rod can be fixedly installed on the joint bending part by means of a strip pocket or a fixing piece, the strip pocket is similar to a trouser pocket; the fixing piece includes a lace and a connecting block fixed on the lace, the fixing of the connecting block is achieved by means of the lace, and the installation of the angle adjustment rod or the angle fixing rod is achieved by means of the connecting block. This method has a stable and reliable structure and is easy to install.

[0028] At the same time, the physiotherapy device integrates a heart rate monitoring module and a timing module, and communicates with the control module to achieve real-time monitoring of multiple parameters during the physiotherapy process. The system can automatically adjust the air pressure intensity according to the combined changes of heart rate and time, or preset a smart reminder for the physiotherapy duration, forming a "monitoring-feedback-adjustment" closed loop to improve the safety and efficiency of physiotherapy.

[0029] At the same time, by providing a physiotherapy device control method, the air pressure of the physiotherapy device can be controlled in combination with heart rate and time, and the user can be given the best pressure for physiotherapy in combination with age and gender, so that the physiotherapy can be achieved at the best effect, and the patient's discomfort can be reduced and the user's physiotherapy situation can be monitored at any time, so as to stop the physiotherapy in time or change the physiotherapy method.

Detailed Description of the Embodiment

[0031] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0032] In this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0033] As described in the background art, in order to adapt to the human physiological structure, existing long-type air pressure physiotherapy devices usually include the joint activity area in the physiotherapy range, and their airbag design adopts a preset bending angle to match the conventional joint morphology. However, in clinical applications, it is found that such a design has the following limitations.

[0034] Insufficient adaptability: The preset bending angle is designed based on the joint mobility of the general population. For special groups with joint stiffness and limited mobility (such as patients with arthritis, postoperative immobilization or congenital deformities), the preset angle may far exceed their actual physiological bending arc. Contradiction between therapeutic effect and comfort: When the preset angle is greater than the actual bending ability of the patient's joint, excessive stretching or local high pressure will be generated in the airbag during the inflation process, resulting in pain and discomfort. If the discomfort is relieved by reducing the air pressure, it is difficult to reach the effective physiotherapy pressure threshold, forming a dilemma of "insufficient therapeutic effect when discomfort is reduced, and poor tolerance when the therapeutic effect is ensured".

[0035] For the above reasons, the present embodiment provides a physiotherapy device, which includes an air pressure physiotherapy module and a control module. The control module is used to control the air pressure of the air pressure physiotherapy module, and the air pressure physiotherapy module acts on the limb of the user, such as Figure 11 shown, the air pressure physiotherapy module 200 has at least one joint bending part 210, such as Figure 8 and Figure 9 shown, a curvature maintaining device 100 is installed on one side or both sides of the joint bending part; such as Figures 1 - 4 shown, the curvature maintaining device includes an included angle adjusting rod 102, an included angle fixing rod 101 and an included angle maintaining member 106. The included angle adjusting rod is fixed to one end of the bending part, and the included angle fixing rod is fixed to the other end of the bending part; optionally, the included angle maintaining member 106 can be a screw or a plug.

[0036] The included angle adjusting rod 102 is provided with an included angle adjusting portion 103. The end of the included angle fixing rod 101 is rotatably connected to the included angle adjusting portion 103. An included angle fixing hole is formed in the included angle fixing rod 101. A plurality of circumferentially arranged angle adjusting holes 1031 are formed in the included angle adjusting portion with the rotation center of the included angle fixing rod as the center of the circle. The included angle maintaining member 106 passes through the included angle fixing hole and is inserted into one of the angle adjusting holes.

[0037] The above technical features can realize the adjustment and maintenance of the bending angle of the bending portion, so as to reduce the discomfort of special populations (such as patients with arthritis, postoperative immobilization or congenital deformities) during physical therapy due to the mismatch between the joint bending degree and the preset radian. The adjustment and maintenance device realizes the adjustment of the included angle through the included angle adjusting rod and the included angle fixing rod fixed to the bending portion, and uses the included angle maintaining member to fix the included angle. The structure is simple and the operation is convenient; an included angle adjusting portion is provided on the included angle adjusting rod. The included angle adjusting portion has a plurality of circumferentially arranged angle adjusting holes, and the plurality of angle adjusting holes are arranged with the rotation center of the included angle fixing rod as the center of the circle, which can realize the adjustment of multiple angles of the included angle adjusting rod and the included angle fixing rod to adapt to different populations. At the same time, the included angle adjusting portion is located at the end of the included angle adjusting rod. While realizing the rotational connection between the included angle adjusting rod and the included angle fixing rod, the length of the included angle adjusting rod is effectively controlled, and the included angle adjusting portion is semi-circular with a hollow design in the middle. The semi-circular design provides a layout space for a plurality of angle adjusting holes, and the hollow design reduces the weight and material consumption, and is convenient for the staff to take and store.

[0038] In order to realize the rotational installation of the included angle adjusting rod 102 and the included angle fixing rod 101, in one embodiment, as Figure 2 、 Figure 3 and Figure 5 shown, a mounting shaft 105 for rotatably installing the included angle fixing rod is fixedly provided on the included angle adjusting portion 103. A plurality of circumferentially arranged elastic positioning members 1051 (such as ball head set screws) are provided at the front part of the mounting shaft 105.

[0039] The above technical features fixedly provide a mounting shaft on the included angle adjusting portion, which can realize the rotational installation of the included angle fixing rod. By fixedly providing the mounting shaft, the risk of component loss is reduced, and the installation process of components is also reduced. And a plurality of circumferentially arranged elastic positioning members (similar to ball head set screws) are provided on the mounting shaft, which reduces the risk of the included angle fixing rod falling off after installation, and is also convenient for installing and disassembling the included angle fixing rod.

[0040] In order to adapt to the installation of the included angle adjusting rod and the included angle fixing rod at different angles and installation spaces, in one embodiment, as Figure 1 、 Figure 2 and Figure 4As shown, the angle adjustment rod 102 and / or the angle fixing rod 101 are provided with a telescopic sleeve 104, the telescopic sleeve 104 has a mounting strip hole 1041 in the length direction, and a plurality of telescopic adjustment holes 1042 arranged along the length direction of the telescopic sleeve are provided on the telescopic sleeve, and a positioning piece 107 (such as a ball head screw) matching the telescopic adjustment hole is provided on the angle adjustment rod and / or the angle fixing rod.

[0041] The above technical features can realize the installation and fixation of the angle adjustment rod or the angle fixing rod in different spaces, and also improve the installation stability of the angle adjustment rod or the angle fixing rod. The length of the angle adjustment rod or the angle fixing rod can be changed by the telescopic sleeve, which improves the stability of maintaining the angle, and is also convenient for fixing the angle adjustment rod or the angle fixing rod to adapt to various angle changes; because the smaller the angle, the greater the force required to maintain the angle during inflation. If the angle is fixed with more points of force or longer length, it is easier to provide the holding force. After changing the length, more fixing points or farther fixing points can be provided to provide better holding force and reduce the risk of falling off. At the same time, by setting a number of telescopic adjustment holes arranged along the length direction of the telescopic sleeve on the telescopic sleeve, the telescopic length can be adjusted to provide better holding force. At the same time, it can also adapt to the installation of the angle adjustment rod or the angle fixing rod in different situations. For example, in the bending part of the ankle, the space is limited, so the angle adjustment rod or the angle fixing rod is not easy to be too long, which will lead to inconvenience in installation.

[0042] In order to facilitate the storage of the curvature retaining device when not in use, in one embodiment, the distance between the elastic positioning member 1051 and the angle adjustment portion is not less than the thickness of the telescopic sleeve installed on the angle fixing rod. Figure 6 and Figure 7 As shown). At the same time, a storage hole 1021 for placing an angle retaining member is provided on the angle adjustment portion 103 or the angle adjustment rod 102. The storage hole can prevent the loss of parts and improve the durability of the device.

[0043] In order to better fix the angle adjustment rod and the angle fixing rod to the air pressure therapy module, in one embodiment, as shown in FIG. Figures 8 - 10As shown, the included angle adjusting rod and the included angle fixing rod are fixedly installed on the joint bending part through the strip pocket 400 or the fixing member 300; the strip pocket is provided on the air pressure physiotherapy module; the fixing member 300 includes a lace 301 and a connecting block 303 fixed on the lace. One end of the lace has an anti - detachment head 302. During use, one end of the lace is inserted into the anti - detachment head; the connecting block 303 has an installation through - hole 304 adapted to the included angle adjusting rod or the included angle fixing rod. The included angle adjusting rod or the included angle fixing rod is fixedly installed on the joint bending part by using the strip pocket or the fixing member. The strip pocket is similar to a trouser pocket; the fixing member includes a lace and a connecting block fixed on the lace. The connecting block is fixed by means of the lace, and the included angle adjusting rod or the included angle fixing rod is installed through the connecting block. This way has a stable and reliable structure and is convenient to install.

[0044] In order to better monitor the heart rate change of the user during the physiotherapy process, in one embodiment, it further includes a heart rate monitoring module and a timing module that communicate with the control module.

[0045] The above - mentioned technical features can realize the multi - parameter real - time monitoring of the physiotherapy process, automatically adjust the air pressure intensity according to the combined change of heart rate and time, or preset the physiotherapy duration for intelligent reminder, forming a "monitoring - feedback - adjustment" closed - loop, improving the safety and efficiency of physiotherapy.

[0046] Due to differences among users (such as age and gender), different air pressures are applied during physiotherapy. And when special groups use it, there may be changes in heart rate, and this heart rate change may be a short - term phenomenon (for example, when special groups or first - time users of air physiotherapy may have a high heart rate due to nervousness, and as they further adapt and the nervous emotion is eliminated, the heart rate drops). Therefore, in order to better control the pressure of the physiotherapy device, in one embodiment, as Figure 12 shown, a control method for a physiotherapy device is provided, including the following steps: S100. Obtain the body parameters of the user, and the body parameters at least include gender and age.

[0047] S200. Determine a threshold group and an air pressure adjustment value △P according to the body parameters.

[0048] The threshold group includes a heart rate threshold HR 标准 adapted to age and gender, a limit heart rate threshold HR 极限 , a standard air pressure value P 标准 and a time value; the time value includes a first time value T 1 (such as 30 seconds), a second time value T 2 (such as 60 seconds) and a third time value T 3 (such as 90 seconds), where T 1 <T 2<T 3 The heart rate threshold, maximum heart rate threshold, standard air pressure value, and time value are preset in advance according to parameters such as the user's age and gender. Since the heart rates of children, young people, and the elderly are different under the same conditions and also vary according to gender, they can also be preset according to the user type (such as athletes). The standard air pressure value P 标准 is a range value because during physical therapy, physical therapy is achieved through changes in pressure. The air pressure adjustment value △P refers to the adjustment degree when adjusting the air pressure and is preset in advance. The maximum heart rate threshold HR 极限 is the maximum limit value. After exceeding this value, it is necessary to immediately stop physical therapy and reset the air pressure to zero.

[0049] The threshold group is a preset value and is stored in the database of the control module in a modular form according to age stages and gender types. When needed, just select the corresponding module, and the threshold group will be automatically formed.

[0050] Exemplarily, the specific manner of step S200 is as follows: When used by the user or staff (such as medical staff or the user's family members, etc.), according to the user's physical parameters, select the user type (such as male / female children, male / female young people, male / female elderly people, athletes), and the corresponding threshold group will be automatically matched and generated.

[0051] S300. Start the pneumatic physical therapy device to perform physical therapy on the user according to the start signal, and adjust the pressure of the air pressure physical therapy module according to the control logic.

[0052] Exemplarily, as Figure 13 shown, the control logic is as follows: S301. Monitor the user's real-time heart rate HR 实时 and the real-time pressure P 实时 of the air pressure physical therapy module; S302. When the real-time heart rate HR 实时 ≤ heart rate threshold HR 标准 , then maintain the standard air pressure value P 标准 ; S303. When the real-time heart rate HR 实时 > heart rate threshold HR 标准 , start the timer and execute the pressure adjustment logic, otherwise reset the timer.

[0053] Exemplarily, as Figure 14 shown, the pressure adjustment logic includes: S3031. When the timing duration T of the timer ≥ the first time value T 1 (such as 30 seconds), then reduce the pressure of the air pressure physical therapy module according to the air pressure adjustment value; Exemplarily, the method for reducing air pressure in step S3031 is as follows: P New =P 实时 -△P, P 实时 ∈P 标准 ; where P New is the new adjusted pressure value, and P 实时 is the real-time pressure.

[0054] S3032. When the real-time heart rate HR 实时 does not decrease or does not decrease to the heart rate threshold HR 2 within the second time value T 标准 (such as 60 seconds), reduce the pressure of the air pressure therapy module by a set multiple of the air pressure adjustment value; Exemplarily, the method for reducing air pressure in step S3032 is as follows: P New =P 实时 -λ△P, where λ is a constant, and the value range of λ is [1.5, 2.5]. The specific value of λ is related to the age, gender or type of the user (such as whether the user is an athlete, etc.), and is preset in the early stage. For example, the value of λ for children is 2, the value of λ for the elderly is 2.5, and the value of λ for athletes is 1.5.

[0055] For example, when the user is an elderly person, when the real-time heart rate HR 实时 > the heart rate threshold HR 标准 and does not decrease or does not decrease to the heart rate threshold HR 2 within the second time value T 标准 (such as 60 seconds), reduce the air pressure by 2.5 times △P (i.e.: P New =P 实时 -2.5△P).

[0056] S3033. When the real-time heart rate HR 实时 ≥ the limit heart rate threshold HR 极限 or the real-time heart rate HR 3 does not decrease or does not decrease to the heart rate threshold HR 实时 within the third time value T 标准 (such as 90 seconds), then set the air pressure to zero and give an alarm.

[0057] The above technical features can control the air pressure of the physiotherapy device by combining the heart rate and time, give the user the best pressure for physiotherapy according to age and gender to achieve the best physiotherapy effect, and can reduce the discomfort of the patient and monitor the user's physiotherapy situation at any time, so as to stop the physiotherapy or change the physiotherapy method in time.

[0058] Furthermore, the control logic further includes: When the continuous physiotherapy duration exceeds the maximum preset time (which is preset according to the user, such as 30 minutes, etc., and this time is also set according to the user's body parameters), the power supply will be automatically cut off and the air pressure will return to zero.

[0059] If the physiotherapy device fails to restart three times in an abnormal state, it will be locked and an alarm will be issued; during the use process, if the device suddenly stops, the control module will attempt to automatically restart it. If the restart fails three times, the physiotherapy device will be stopped and an alarm will be issued to inform the caregiver (the user's medical staff or family member).

[0060] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
