Description

Technical Field

[0001] The invention belongs to the field of medical devices, and relates to a reminder device and method for reminding people to subjectively correct their toe-toe correction. Background Art

[0002] The splayed feet are not only unsightly in appearance, but also cause back pain, and even osteoarthritis in severe cases. The splayed feet need to be corrected by self-training and external force, so as to alleviate a series of problems caused by the splayed feet, such as the medial meniscus of the knee joint, ligament wear, lumbar muscle strain, and gluteal muscle tension. At present, the correction methods for the splayed feet include surgical correction and non-surgical correction. The surgical method is suitable for more serious patients and has greater risks. Non-surgical methods include exercise, orthopedic insoles, correction belts, etc. Most correction instruments on the market use the correction method of passive force on the patient. Long-term external force correction can easily cause varying degrees of damage to superficial blood vessels and nerves, and long-term wearing will cause discomfort to the user. Passive correction takes a long time and can only be used as an auxiliary method. If the user does not develop the correct gait habit voluntarily, it is still difficult to achieve the treatment effect. Therefore, a reminder device and method that can remind patients to subjectively correct the splayed feet are needed, so as to improve the treatment effect of gait and shorten the treatment cycle. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a device and method for correcting pigeon toes that can be subjectively controlled by patients. In order to overcome the problems of long-term passive external force correction in the prior art causing discomfort to users and a long time required for external force correction, a subjectively adjustable pigeon toe gait correction method is provided. The present invention combines gait detection technology, sensors and Bluetooth connection technology. A mobile phone app alarm device can be used to remind users to maintain a correct gait, assist users in developing a habit of a normal gait, reduce discomfort in use, and shorten the gait correction cycle.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: A lightweight wearable device and method for correcting juvenile splayed feet, characterized by: comprising a WT9011DCL-BT50 9-axis Bluetooth 5.0 attitude angle sensor and a smart Witte APP; the sensor integrates a high-precision gyroscope, an accelerometer, a geomagnetic field sensor, and an attitude solver, and adopts a high-performance microprocessor and advanced dynamics solution and Kalman dynamic filtering algorithm, which can accurately output the current attitude of the sensor in a dynamic environment, with an attitude measurement accuracy of 0.2 degrees, extremely high stability, and performance even better than some professional inclinometers; when the sensor detects that the improved step angle is in a splayed foot state, a signal is transmitted to the Witte APP for an alarm reminder; when the improved step angle returns to a normal range, the APP stops the alarm.

[0005] Specifically, the gait is in the splayed position, and the improved step angle is used as the evaluation standard: the midline angle is 0°, the right deviation is a positive value, and the left deviation is a negative value. The right foot minus the left foot step angle is the improved step angle α. -2°<α<30° is a normal gait, α≤-2° or α≥30° are in-toed and out-toed, respectively.

[0006] The sensor can accurately output the current posture of the sensor in a dynamic environment, and can transmit the data to the Witt APP via Bluetooth in real time, which will be processed on the APP terminal and determine whether to remind the patient whether he is in the splayed-leg state.

[0007] The sensor is small in size, only 9 cm³, and is convenient for patients to place on the upper part of the first metatarsal head. It breaks the inconvenience of wearing traditional plastic orthotics, can correct the abnormal gait of splayed feet when walking outside, and shorten the treatment period of splayed feet.

[0008] The beneficial effects of the present invention are as follows: (1) The device and method for correcting the splayed gait of teenagers in real time detects the patient's improved step angle data in real time through the WT9011DCL-BT50 9-axis Bluetooth 5.0 posture angle sensor. When it is detected that the patient is in a splayed gait, a vibration alarm is issued to prompt the patient to correct himself; when the patient is in a normal gait, there is no response, thereby improving the comfort of use.

[0009] (2) The present invention is a device and method for correcting the figure-eight gait of adolescents in real time. The improved step angle collected by the sensor can achieve accurate measurement and real-time recording, and has the function of prompting the wearer to correct the abnormal gait in time.

[0010] (3) The device and method of the present invention for real-time prompting of the figure-eight gait gait of teenagers can monitor the gait in real time around the clock, which can greatly improve the correction effect and shorten the correction time; it can be adapted to shoes of different models, is compact and light, and has a high cost-effectiveness.

[0016] Implementation

[0017] First, determine the assessment criteria for splay feet, screen out patients with splay feet, and then select the appropriate sensor. The sensor can accurately output the current posture of the sensor in a dynamic environment, and can transmit the data to the Witt APP in real time via Bluetooth. The APP terminal processes the patient's walking foot data to determine whether the patient is in a splay foot state. If it exceeds the set value, an alarm will be sounded; if it is within the normal range, no alarm will be sounded. Finally, regular trail detection and comparison will be performed, and this process will be repeated until the gait is corrected to a normal state.

[0018] The following is an explanation of the implementation of the present method by means of specific examples, and the disclosed contents make it easy to understand other advantages and effects of the present method.

[0019] See also Figure 1-2 , which is an automatically adjustable toe correction device, including circuit principle Figure 1 , hardware size 2.

[0020] When the feet are in the splayed position, there is a significant difference in the step angle. Therefore, the improved step angle can be used to collect data, calculate the angle offset, and then detect the gait.

[0021] The sensor is equipped with a high-precision gyroscope, accelerometer, geomagnetic field sensor, and attitude solver; with the dynamic Kalman filter algorithm, it can accurately output the current attitude of the sensor in a dynamic environment, and the attitude measurement accuracy is 0.2 degrees, with extremely high stability. When the sensor calculates the improved step angle and determines that the gait is inward and outward, the alarm reminder is transmitted to the Witt Smart APP via Bluetooth to trigger the reminder function, prompting the patient to improve the gait, so as to control and maintain the correct gait.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
