Description

Human body balance ability detection and training device based on movable and static conversion of medium bag

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a device for detecting and training human body balance ability.

Background

Balance ability refers to the ability to maintain body posture, particularly on small support surfaces, controlling the body's center of gravity. Balance ability is the fundamental ability of all static and dynamic activities of human beings. Almost all human movements are performed in a state of maintaining physical balance, which is influenced by a number of factors, which compensate and influence each other. The balance ability of the human body is used as a basic ability of the human body, plays a very important role in the daily life of normal people, and is particularly helpful for early warning and targeted training of certain diseases by determining and understanding the balance ability of the old people or people suffering from certain diseases in advance. For example, the falling of the old can be early warned, and corresponding training is carried out to reduce the falling.

The current balance capability detection equipment mainly comprises static balance and dynamic balance. Static balance detection is mostly based on a plantar pressure sensor, the balance capability of a human under a static non-disturbance condition is measured, and the test precision is limited. In order to increase the testing precision, a tester is usually required to complete a specific testing action, such as standing on one foot, closing eyes, squatting and the like, and the procedure is relatively complicated. In addition, the static balance detection equipment is difficult to realize the improved training of people with the defective balance capacity because the movement is difficult to generate. The detection platform of the dynamic balance detection equipment can automatically generate disturbance after a human body stands, the balance capability is measured by evaluating the capability of a detected person controlling the human body to reduce the disturbance amplitude, and the test equipment is higher in relative test precision. Meanwhile, the dynamic balance detection equipment has the characteristic of free disturbance, and can realize rehabilitation training corresponding to the balance capability through setting of a specific action curve and a program.

The realization of dynamic balance is realized by combining an inertial sensor or a plantar pressure sensor with a corresponding mechanism with a disturbance function at present. Such as korebance's inertial sensor plus air bladder approach, and modes based on water bladder and plantar pressure sensors. Although dynamic balance capability testing has many advantages, for some people with poor balance capability or some special groups, stability cannot be easily kept on equipment, actual testing has certain difficulty, and particularly for portable testing equipment, corresponding handrails or auxiliary devices are not usually arranged, so that the portable testing equipment is more inconvenient. Therefore, if one device has static balance and dynamic balance detection capability at the same time, and the two devices can be easily switched at some time, the device has practical significance for practical use and expansion of the application range of the device.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 to 10 are schematic structural views showing respective components of the balance ability detecting and training apparatus according to an exemplary embodiment of the present invention. In this embodiment, the balance ability detecting and training device based on the movable-static conversion of the medium bag sequentially comprises an upper plate assembly 1, a balance ability collecting module 2, a medium bag 3 and a base 4 from top to bottom.

The material of the medium bag is flexible, and rubber and silica gel are recommended. The balance ability acquisition module 2 is arranged at the upper part of the medium bag 3 and comprises a base plate 21, a plantar pressure sensor 22 for acquiring reaction balance ability, and a data processing and analyzing module connected with the sensor, wherein the data processing and analyzing module can be integrated in a structure shown in the figure and can also be independently arranged as required, for example, the data processing and analyzing module is externally connected through a data line of the sensor and is simultaneously arranged in a module with a display screen. The pressure sensor 22 is further provided with a coating 23, preferably a flexible film material, preferably a polymer fabric such as cloth. Then the periphery of the covering plate 23 is provided with a fixing member for fixing the covering film 23 on the bottom plate 21 of the balanced acquisition module. In addition, a film-covered fixing piece 24 is arranged on the uppermost layer of the balance capacity acquisition module, the film-covered fixing piece 24 is connected with the substrate 4, and the data processing and analyzing module is packaged between the film-covered fixing piece 24 and the substrate 4.

The medium bag is filled with water usually, because the medium bag is made of soft materials, when the medium bag is contacted with the balance ability acquisition module 2 (at a second position), a tested person stands on the device of the invention and then stands on the medium bag indirectly, the medium bag amplifies the shaking of the tested person, and when the balance ability is in problem, the tested person is difficult to keep the stability of the tested person and is easy to generate large-amplitude shaking; greater wobble amplifies the smaller balance problem, and thus better test accuracy is easily achieved. When the dynamic and static conversion mechanism is operated, the balance capacity acquisition module 2 is supported and separated from the medium bag, a tested person only stands on a fixed platform with a sensor, and the body of the tested person cannot shake due to external disturbance, so that the extraction and analysis of small balance capacity difference are limited. The medium in the medium bag is preferably water from the viewpoint of convenience of installation, but gas can be selected, and the hardness of the medium bag as a whole can be adjusted by adjusting the pressure of the gas. Other single or complex viscous substances may also be used as the medium. The corresponding medium bag of this embodiment is provided with water inlet and air outlet. When water is injected, water is injected from one end until the water flows out from the other end and all air in the medium bag is discharged. The hardness of the whole medium bag can be adjusted by the hardness of the material of the medium bag, the quantity of the internal medium, the base and other external constraints. Different hardness degrees can affect the accuracy of the balance capability test. The hardness of the material can be selected according to the requirements on precision, the overall stability and safety of a tested person after standing and other factors.
