Problems solved by technology

[0003] In order to accurately and real-time measure the actual movement angle of the limbs wrapped by the brace, the patent No. ZL201420552410.2 discloses an ankle joint training device that is easy to adjust, and the patent No. ZL201420552058.2 discloses an easy-to-adjust ankle joint training device. Wrist joint training device, the patent No. ZL201620839432.6 discloses an elbow joint rehabilitation training device with the function of adjusting and measuring angles. These devices all have the function of measuring rotation angle, but the disclosed angle measurement methods are all for Specially designed braces that cannot be fitted with other braces
There are many types of sports braces on the market today, but almost none of them consider reserving interfaces for angle measurement, nor do they reserve installation positions for such angle measurement accessories
Therefore, there is currently no angle measuring device that can adapt to various sports braces, which is a blank in the industry.

Embodiment 1

[0039] like figure 1 , 2 As shown in , 3, it includes a measurement terminal and a host computer wirelessly connected to the measurement terminal; the measurement terminal also includes a housing 4, and a fixed joint 1 arranged on the back of the housing 4 is arranged on the outside of the housing 4 and the bottom end passes through the housing 4 of the transmission connector 5, the potentiometer 2 arranged inside the housing 4 and connected to the end of the transmission connector 5, and the circuit board 3 arranged inside the housing 4 and connected to the potentiometer 2; The host computer is connected with the circuit board 3 through a wireless network.

[0040] The housing 4 is composed of an upper case 41 , a lower case 42 matching the upper case 41 , and a key switch 43 whose base is arranged inside the upper case 41 and whose key passes through the upper case 41 .

[0041] The shape of the housing can be set according to actual needs, and can be a cuboid, a cylinder ...

Embodiment 2

[0053] like Image 6 As shown, a method for using a general-purpose single-degree-of-freedom motion brace angle measuring device includes the following steps:

[0054] (1) Fix the measuring end on the sports brace;

[0055] (2) Establish a communication connection with a host computer provided with a software program through the bluetooth module in the measurement terminal;

[0056] (3) Select the type of sports brace in the host computer;

[0057] The brace types include elbow braces, knee braces, ankle braces, and more.

[0058] (4) Select the hinge structure type in the host computer;

[0059] The hinge structure types that this product can measure are single-axis hinges or double-axis hinges.

[0060] (5) The upper computer collects the parameters of the sports brace during use through the measuring terminal;

[0061] The specific process of collecting the motion parameters of the sports brace at the measuring end is as follows: firstly, the potentiometer will change ...

Embodiment 3

[0067] This embodiment is a method for using the present invention in conjunction with a sports brace with a single-axis hinge.

[0068] like Figure 4 As shown, the single-axis hinge structure of the sports brace is mainly composed of two hinge pieces and a rotating shaft for connecting the two hinge pieces, wherein one hinge piece is located on the outside and the other hinge piece is located on the inside. When setting, first align the rotating shaft of the potentiometer with the rotating shaft, that is, the fixed end of the rotating shaft coaxial with the rotating shaft of the potentiometer is set coaxially with the rotating shaft, and then the fixed joint is adsorbed or bonded to the hinge piece located on the outside, and then through Adjust the column bolt on the fixed end of the hinge so that the fixed end of the hinge can fit on the inner hinge piece, and fix it by adsorption or bonding. When fixing, the optimal position of the fixed end of the hinge is the center lin...

Abstract

The invention discloses a universal single-degree-of-freedom motion brace angle measuring device, comprising a measuring end and a host computer wirelessly connected to the measuring end, wherein themeasuring end further comprises a housing, a fixed joint disposed on the back of the housing, a transmission connector arranged at the outer side of the housing and with the bottom end penetrating thehousing, a potentiometer disposed inside the housing and connected to the end of the transmission connector, and a circuit board disposed inside the housing and connected to the potentiometer. The invention also discloses a method for using a universal single-degree-of-freedom motion brace angle measuring device, which comprises the steps such as fixing the measuring end to the motion brace. Theinvention provides a universal single-degree-of-freedom motion brace angle measuring device, which can adapt different types of brace as much as possible without any modification to the sports brace,and minimize the installation difficulty, thereby largely increasing the range of application and use effect of the product, and reducing the user's cost of use.

Description

technical field [0001] The invention belongs to the field of sports brace measurement, in particular to a general-purpose single-degree-of-freedom sports brace angle measurement device. Background technique [0002] Sports brace is a joint support and protection device widely used in medicine. On the one hand, this type of equipment provides protection and support for the joints and nearby bones and muscles, and on the other hand, it can also ensure that the joints can move freely within a safe range. At present, the structure of most sports braces is relatively simple, and the purpose of use is only to realize the above-mentioned protection and support functions, and it is impossible to measure the actual angle of motion of the joint during use in real time. However, in the practice of rehabilitation medicine, the patient's joint range of motion in daily life can be directly converted into the measurement values ​​of multiple scales, and the doctor can also accurately grasp...
