Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a wearable motion information collection device and a balance rehabilitation training system. Background Art

[0002] Vestibular rehabilitation therapy is a training-based treatment for patients with vestibular dysfunction. It improves the coordination and control of balance by vestibular, visual and proprioceptive senses, mobilizes the compensatory function of the central nervous system, reduces or eliminates dizziness and vertigo symptoms, prevents falls, and improves the quality of life of patients. Problems with any of the three senses, proprioception, vision and vestibular sense, or imbalance in the integration process, can lead to vertigo or balance dysfunction.

[0003] At present, for patients who need balance rehabilitation training, the rehabilitation training provided includes gaze stability training, balance function training, etc. Taking gaze stability training as an example, most clinicians use on-site teaching to familiarize patients with several sets of gaze stability training paradigms (gaze stability training devices can be used), and instruct patients to conduct rehabilitation training according to the recorded vestibular rehabilitation training videos after returning home. For balance function training, dynamic / static balance tables in hospitals are generally used for diagnosis and treatment of balance function.

[0004] However, these methods currently have the following shortcomings:

[0005] If neither gaze stability training nor balance function training uses equipment training, and users are only allowed to use their own home devices to train according to the training videos, on the one hand, patient compliance is poor, and on the other hand, it is difficult for doctors to judge the training situation during follow-up visits. If training equipment is used, since gaze stability training and balance function training use different auxiliary training equipment, patients who need to perform these two types of training need to be equipped with different training equipment, which undoubtedly greatly increases the cost for patients. In particular, the dynamic / static balance table equipment used for balance function training (the balance table has a built-in pressure sensor to collect the center of gravity change information of the user on the table) has a relatively high cost and is slightly large in size. It is neither portable nor suitable for home rehabilitation training.

[0006] Moreover, different auxiliary training devices often use different hosts to collect motion information. Patients need to frequently switch clients and connect data with multiple hosts when performing different rehabilitation training. The operation is cumbersome and is particularly inconvenient for middle-aged and elderly patients.

[0007] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary technicians in this field need to solve urgently. Utility Model Content

[0020] In some embodiments, the male buckle is a rotating body structure. When the male buckle is inserted into the female buckle, the host can rotate around the central axis of the male buckle relative to the belt seat to adjust the reference plane of the posture sensor to a position parallel to the sagittal plane of the user's body.

[0021] In some embodiments, the belt seat has a rough surface at least on the peripheral side of the male buckle or the female buckle, and is in frictional contact with the host so that the host is maintained at a certain rotation angle.

[0022] In some embodiments, the belt seat is provided with two flanges around the male buckle or the female buckle, and a mounting position for mounting the host is formed between the two flanges; and,

[0023] The outline dimension of the installation position formed by the two flanges is larger than the outline dimension of the side where the host is installed on the belt seat, and the two flanges are used to limit the rotation of the host within a specific angle range.

[0024] In some embodiments, a gap is formed between the two flanges at both ends in the extending direction of the flanges, and the gap forms an opening structure on the installation position; and the host is provided with a slot corresponding to the opening structure.

Different belt seats and / or different wearing belts can match different parts of the user. By replacing the belt seat or changing the wearing position of the belt seat to wear the host to different parts of the user, the motion information of different parts of the user can be collected, which is convenient for the user to train different parts. For example, when the host is worn on the head, the user can perform gaze stability training, and when the host is worn on the waist, the user can perform balance function training. There is no need to equip different training equipment, and the cost is low. At the same time, because the user uses the wearable motion information collection device provided by the present application as an auxiliary device to train different parts, the host used is the same. Compared with the situation where multiple hosts are equipped with multiple belt seats, the user does not need to frequently switch the client and multiple host data connections, which greatly simplifies the user's operation and is highly practical.

[0036] 2. In the present application, a quick-release structure is also provided between the main unit and the belt seat. The quick-release structure includes a male buckle and a female buckle.

The user can directly adjust the reference plane of the posture sensor in the host by rotating the host for subsequent training and effect evaluation. In addition, this application also sets a flange on the outer periphery of the host on the belt seat to limit the rotation angle of the host to prevent elderly users from blindly adjusting and over-adjusting, which affects the training effect.

[0049] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0050] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0051] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0052] In this document, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integral connection; or it can be a mechanical connection, or it can be an electrical connection; or it can be a direct connection, or it can be indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] In the embodiments shown in the drawings, directional indications (such as up, down, left, right, front, and back, etc.) are not absolute but relative when describing the structure and movement of each component, and are not used to limit the direction of the product in actual use.

[0054] In addition, in the description of the present application, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe related objects, and cannot be understood as indicating or implying the relative importance or order between the related objects.

[0055] See also Figure 1 In a specific embodiment, the present application provides a wearable motion information collection device, including a host 100 and a wearing support assembly, wherein the number of the host 100 is one, and the wearing support assembly includes at least one belt seat 200 and at least one wearing belt 400. The belt seat 200 is used to support the host 100, and the host 100 and the belt seat 200 are detachably connected. Specifically, the host 100 and the belt seat 200 are connected and separated through a quick-release structure 300; the wearing belt 400 is used to fix the belt seat 200 and the host 100 installed on the belt seat 200 to the corresponding body part of the user.

[0056] In actual production, different belt seats and / or different wearing belts can match different parts of the user. By replacing the belt seat or changing the wearing position of the belt seat, the host can be worn to different parts of the user.

[0057] The host 100 includes a shell with a built-in posture sensor for collecting the user's movement information. When the host 100 is fixed to different parts of the user, the posture sensor can collect the movement information of different parts of the user to assist the user in rehabilitation training.

[0058] For example, when the host 100 is worn on the user's head, the wearable motion information collection device can be used to assist the user in gaze stability training. Specifically, after the user wears the host 100, he looks at the moving target on the front display and turns his head. The posture sensor in the host 100 collects the angle and acceleration of the user's head rotation and transmits the collected information to the client (computer software or mobile phone APP). The client controls the moving distance and speed of the target. At the same time, the client can also calculate the matching degree between the user's head rotation and the target movement, and then evaluate the training effect.

[0059] When the host 100 is worn on the user's waist, the wearable motion information collection device can be used to assist the user in balance rehabilitation training. Relatively speaking, after the user wears the host 100, he swings his waist according to the prompts of the display screen. The posture sensor in the host 100 collects the amplitude and acceleration of the user's waist swing. Specifically, it actually collects the motion information of the host, but because the host is worn on the waist, preferably, worn on the waist and back, the deflection angle, angular velocity, acceleration and other motion information of the waist movement are collected. The center position of the waist and back is actually close to the center of gravity of the human body. Collecting the motion information of the waist and back through the wearable motion information collection device is actually equivalent to collecting the user's center of gravity change information, without the need to collect pressure changes through the pressure sensor of the balance platform to characterize the center of gravity change; finally, the collected waist and back motion information is transmitted to the client (computer software or mobile phone APP). The client outputs the amplitude and speed of the user's equivalent center of gravity swing to the display screen in real time, and calculates the actual equivalent center of gravity change of the user and the matching degree of the preset rehabilitation training program, and then evaluates the training effect.

[0060] The wearable motion information collection device provided in this embodiment can be used to assist users in both gaze stability training and balance function training. It has a wide range of applications, and users do not need to be equipped with different auxiliary training equipment, which is low cost. Moreover, compared with multiple sets of auxiliary training equipment that require multiple hosts 100, this embodiment only uses one host 100. When users switch between different trainings (such as switching between gaze stability training and balance rehabilitation training), they do not need to frequently switch computer software or mobile phone APPs to connect to multiple hosts 100 data, which greatly simplifies the user's operation, is conducive to the advancement of the rehabilitation training process, and is more convenient for elderly users to use, and has strong practicality.

[0061] Among them, the display screen that can interact with the host 100 can be a display screen of a computer or a mobile phone (client), or a television, etc. The user can use the wearable sports information collection device provided in this embodiment to perform home training at home.

[0062] In actual production, the wearing support assembly may include a first belt seat and a second belt seat. The first belt seat is a head belt seat that can match the user's head and fix the host to the user's head through a wearing belt; the second belt seat is a waist belt seat that can match the user's waist and fix the host to the user's waist through a wearing belt.

[0063] The specific structure of the head belt seat and the specific structure of the waist belt seat may be the same or different.

[0064] If the specific structure of the head belt seat is the same as the specific structure of the waist belt seat, in a specific embodiment, one belt seat can also be used with different wearing belts to wear the host to different parts of the user. Specifically, the wearing support assembly may include a first wearing belt and a second wearing belt, the first wearing belt is preferably a headband, and the second wearing belt is preferably a waist belt. When the same belt seat is matched with the first wearing belt (headband), the host can be fixed to the user's head, and when it is matched with the second wearing belt (waist belt), the host can be fixed to the user's waist. Of course, the wearing belt can also adopt an adjustable structure, such as a strap, an adjustment rope, Velcro, etc. In this case, the same belt seat only needs to be matched with one wearing belt, and the belt seat and the host on the belt seat can be fixed to different parts of the human body by changing the circumference of the wearing belt.

[0065] If the specific structure of the head belt seat is different from that of the waist belt seat, different belt seats can be used with corresponding wearing belts. That is, the head belt seat corresponds to the headband, and the waist belt seat corresponds to the waist belt. In contrast, the wearing belt can also adopt an adjustable structure, such as a strap, an adjustment rope, Velcro, etc. In this case, different belt seats only need to be matched with one wearing belt, and the head belt seat and the waist belt seat can be fixed to the corresponding parts of the human body by changing the circumference of the wearing belt.

[0066] Specifically, see Figures 1 to 3 The quick-release structure 300 includes a male buckle 310 and a female buckle 320. The male buckle 310 is convex and the female buckle 320 is concave. The two can be engaged and disengaged with each other. The host 100 is provided with one of the male buckle 310 and the female buckle 320, and the belt seat 200 is provided with the other of the male buckle 310 and the female buckle 320. The connection and separation between the host 100 and the belt seat 200 can be realized by engaging and disengaging the male buckle 310 and the female buckle 320, which is conducive to the quick disassembly and assembly between the host 100 and the belt seat 200, and convenient for users to quickly replace the required belt seat 200, and easy to operate.

[0067] In one example embodiment, see Figure 1 The male buckle 310 is preferably a rotating body structure, for example, a round shaft structure with a protrusion. When the male buckle 310 is inserted into the female buckle 320, the host 100 can rotate around the central axis of the male buckle 310 relative to the seat 200.

[0068] In all the above embodiments, the posture sensor in the host 100 preferably adopts a gyroscope. The angle deflection data measured by the gyroscope is based on the Euler angle, and the Euler angle is used to represent the direction and direction transformation in the three-dimensional coordinate system. Before training, the coordinate system of the gyroscope is adjusted to be consistent with the axis of the human body coordinate system, or one or two axes are consistent, which can simplify the gyroscope data solution algorithm, improve the data calculation efficiency, and respond faster in real time and calculate data more accurately. In addition, there is a universal lock phenomenon when the gyroscope measures the Euler angle. When the second axis rotates to plus or minus 90 degrees, the posture is locked, and the rotation "effect" of the third axis and the first axis is the same, that is, the gyroscope measures the angles of the three axes, the X-axis roll angle range is ±180°, the Y-axis pitch angle range is ±90°, and the Z-axis yaw angle range is ±180°. Therefore, the gyroscope has an axial rotation angle that is locked at plus or minus 90 degrees. If the wearing angle deviation is too large, the range in this direction will become smaller, and the left and right ranges will be asymmetric. Assume that when the host 100 is worn on the waist, the heights of the belt on the left and right are inconsistent, causing the host 100 to tilt 10 degrees to the left. Then the tilt range for measuring the left and right directions is 80° to the left to 100° to the right. In this case, the left tilt measurement range becomes smaller, affecting the gyroscope measurement data.

[0069] Most of the existing technical solutions adjust the host 100 to be parallel to the sagittal plane of the human body as much as possible by adjusting the wearing of the belt to achieve the purpose of axial consistency. For example, the right side of the belt is higher than the left side, causing the host 100 to tilt to the left. The user pulls down the right side of the belt to level it, but the precision is poor. Moreover, because the belt and the waist are flexible, it is difficult to accurately level it, and the wearing position of the belt needs to be adjusted multiple times.

[0070] In this embodiment, the reference plane of the posture sensor in the host 100 can be leveled directly by rotating the host 100, which has higher precision and does not need to adjust the wearing position of the wearing belt 400 (waist belt, headband, etc.) multiple times. It is easy to operate and is beneficial to improving the accuracy of information collected by the posture sensor and improving the user's training effect.

[0071] Specifically, the belt base 200 is preferably made of a flexible material so that the belt base 200 can better fit the corresponding part of the human body. At the same time, the belt base 200 has a rough surface at least on the side of the male buckle 310 or the female buckle 320, which is in friction contact with the host 100 to form a friction pair, so that when the host 100 rotates on the belt base 200, the damping feeling can be maintained, and the adjusted angle position can be maintained after leveling.

[0072] Preferably, see Figure 1 and Figure 2Taking the example that the male buckle 310 is arranged on the belt seat 200 and the female buckle 320 is arranged on the host 100, the belt seat 200 can also be provided with a groove 240 on the male buckle 310 bearing, and the host 100 is provided with an outward protrusion 130 corresponding to the position of the groove 240, which can increase the contact area between the host 100 and the belt seat 200 to a certain extent, further expand the friction resistance between the host 100 and the belt seat 200, and have a better damping effect, which is conducive to keeping the host 100 in the adjusted position.

[0073] To further improve the accuracy and convenience of the posture sensor leveling, the client can prompt the user whether the current position of the host 100 is crooked. Specifically, a dotted frame and a solid frame will be displayed on the display screen. The dotted frame is the ideal angle position of the host 100, that is, the position of the host 100 parallel to the sagittal plane of the human body, and the solid frame is the real-time angle position of the host 100. The user can achieve the leveling of the posture sensor reference plane by adjusting the solid frame to a position consistent with the dotted frame.

[0074] Specifically, see Figure 4 , taking the male buckle 310 being arranged on the belt seat 200 and the female buckle 320 being arranged on the host 100 as an example, the belt seat 200 is provided with two flanges 210 on the circumference of the male buckle 310, and an installation position 220 for installing the host 100 is formed between the two flanges 210, and the outline size of the installation position 220 formed by the two flanges 210 is larger than the outline size of the side of the host 100 installed on the belt seat 200, providing a certain activity space for the rotation of the host 100, and at the same time, the two flanges 210 can limit the rotation angle of the host 100, and the belt seat 200 cleverly utilizes the outer contour shape of the flange 210, so that the user can fine-tune the angle of the host 100 by a small amplitude, which is conducive to the user to adjust the host 100 to the target position more quickly, avoiding blind adjustment and over-adjustment by users, especially elderly users.

[0075] Of course, if the male buckle 310 is set on the main unit 100 and the female buckle 320 is set on the belt seat 200, then the two flanges 210 are set on the belt seat 200 at the side of the female buckle 320. No further details will be given here, and they are all within the protection scope of this application.

[0076] Specifically, the belt seat 200 can be configured to have different bendability characteristics, that is, the bendability between the two flanges 210 (the region of the mounting position 220) is smaller than the bendability of the regions on the left and right sides of the belt seat 200 (the regions outside the mounting position 220). The smaller curvature of the portion is more conducive to the belt seat 200 fitting the human body to ensure wearing comfort; the larger curvature of the portion can ensure the stability of the flange 210 structure, so that when the belt seat 200 is worn on the human body, the flange 210 can be maintained in the initial state, and it is not easy to expand outward due to the bending of the belt seat 200 (especially the region of the mounting position 220 of the belt seat 200), ensuring that the two flanges 210 can play a better role in limiting the adjustment angle.

[0077] Preferably, the belt seat 200 is made of soft rubber, and a metal spring 250 is implanted between the two flanges 210 of the belt seat 200, which effectively improves the supporting effect of the installation position 220 area of ​​the belt seat 200 on the two flanges 210, reduces the risk of outward expansion of the flange 210 during wearing, and the manufacturing process is simple and low-cost.

[0078] Among them, see Figure 5 A plurality of openings 251 are provided on the metal spring 250. On the one hand, the weight of the metal spring 250 can be reduced to a certain extent, thereby reducing the weight of the belt seat 200 and improving the wearing comfort of the user; on the other hand, in the process of injecting glue when making the belt seat 200, the liquid soft glue can fill the openings 251 on the metal spring 250, so that the solidified soft glue fits tightly with the metal spring 250, and the metal spring 250 is not easy to shift or delaminate with the soft glue after long-term use, and has a longer service life.

[0079] Further, see Figures 2 to 4 The two flanges 210 are respectively located on the left and right sides of the host 100 ("left" refers to the position of the host 100 corresponding to the left side of the user after the user wears the host 100, and "right" refers to the position of the host 100 corresponding to the right side of the user after the user wears the host 100), which can protect the host 100 from being scratched during use and reduce the risk of accidental release of the host 100 due to scratches. In addition, the corners of the flange 210 are preferably rounded to avoid scratching the user during use.

[0080] Further, see Figure 1A gap is formed between the two flanges 210 at both ends in the extending direction of the flanges 210, and the gap forms an opening structure 221 on the mounting position 220, that is, the upper and lower sides of the belt seat 200 corresponding to the host 100 ("upper" refers to the position of the host 100 corresponding to the user's head after the user wears the host 100, and "lower" refers to the position of the host 100 corresponding to the user's feet after the user wears the host 100) are in an open state. At the same time, the host 100 is provided with a slot 110 corresponding to the opening structure 221, and the user can drive the host 100 to detach from the belt seat 200 outward by inserting a finger into the slot 110, without the need for other tools, and the operation is convenient and quick.

[0081] In this embodiment, see Figure 2 and Figure 3 The outer contour of the host 100 can be set to an inner beam-shaped structure with a larger end away from the base and a smaller end toward the base, which is more conducive to the host 100 being removed from the installation position 220 and has a beautiful appearance.

[0082] Further, see Figures 1 to 3 The head of the male buckle 310 is mushroom-shaped, and an open spring ring 330 is embedded in the inner wall of the female buckle 320. The open spring ring 330 is in a retracted state in a natural state and can expand and deform outward. When the female buckle 320 and the male buckle 310 are buckled together, the open spring ring 330 can clamp the lower part of the head of the male buckle 310 and is not easy to separate, thereby making the connection between the female buckle 320 and the male buckle 310 more stable, reducing the risk of accidental separation of the host 100 during user training.

[0083] Further, see Figure 1 The belt seat 200 is provided with an indicator mark, which can help the user identify the installation direction of the host 100 and the wearing direction of the belt seat 200, and is more conducive to the user to level the reference plane of the posture sensor according to the instruction and train according to the instruction, so as to facilitate the evaluation of the training effect.

[0084] Specifically, see Figures 1 to 4 The edge of the belt seat 200 is provided with a ring 230, which is used to connect with the wearing belt 400, so that the wearing belt 400 can be used to wear the host 100 to different parts of the user. Specifically, the belt seat 200 is provided with rings 230 on both sides, and the wearing belt 400 passes through the rings 230 of the belt seat 200, so as to fix the belt seat 200 and the host 100 thereon to the corresponding body parts of the user.

[0085] Specifically, the host 100 includes a housing and a posture sensor, an MCU (Micro Controller Unit) main control unit and a data transmission module arranged in the housing. The housing is used to dock with the seat 200, the posture sensor is used to collect the angle and acceleration of the posture change of the host 100, and the MCU main control unit is used to receive the information collected by the posture sensor and is configured to transmit the information to the client through the data transmission module. Among them, the data transmission method can be Bluetooth transmission or other wireless or wired transmission, which is not limited here and is within the protection scope of this application.

[0086] The wearable motion information collection device provided in this embodiment is used under the control and cooperation of the client. Specifically, when the user wears the host 100 on the head (such as gaze stability training), the user looks at the moving target in the front display screen and turns the head. The posture sensor collects the angle and acceleration of the user's head rotation and transmits the collected information to the client. The client controls the moving distance and speed of the target. The client calculates the matching degree between the user's head rotation and the target movement, and then evaluates the training effect.

[0087] See also Figure 1 and Figure 4 If the host 100 further includes a distance measuring module 120, the distance measuring module 120 can be arranged on the surface of the housing to measure the distance from the user's head to the visual target display screen, and the MCU main control unit receives the distance information to obtain the user's position relative to the display screen. The MCU main control unit can transmit the user's position information to the client via the transmission module, and the display screen displays visual targets of different sizes according to the patient's position distance.

[0088] In contrast, when the user wears the host 100 on the waist (such as balance rehabilitation training) and swings the waist, the posture sensor collects the amplitude and acceleration of the user's waist swing and transmits the collected information to the client. The client outputs the amplitude, i.e., speed, of the user's equivalent center of gravity swing to the display device in real time. The client calculates the actual change in the user's equivalent center of gravity and the degree of matching with the preset rehabilitation training plan, and then evaluates the training effect.

[0089] Specifically, the display screen can be a display screen, a television, etc. of the client, or it can be a display screen provided by the wearable motion information collection device. There is no limitation here and all are within the protection scope of this application.

[0090] The present application also provides a balance rehabilitation training system, including a display screen, a client, and a wearable motion information collection device provided by any of the above embodiments, the display screen is communicatively connected to the client, and is used to display training images of rehabilitation training; the wearable motion information collection device is used to collect the user's motion information during rehabilitation training and transmit it to the client, so as to assist the user in performing rehabilitation training under the control and cooperation of the client, such as gaze stability training or balance function training.

[0091] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0092] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
