[0028] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
[0029] With the development of medical technology, the types of equipment used for rehabilitation treatment are becoming more and more diverse. During rehabilitation treatment, users usually use rehabilitation braces to assist rehabilitation treatment. For example, the rehabilitation brace can be a power-assist device. The power-assist device can assist in enhancing human motor function. For example, wearable power-assist devices are currently used to provide power for human joint movements, thereby assisting human movements, improving human load-bearing capacity, and relieving human body fatigue.
[0030] Among them, the types of protective gear can include fabric protective gear, hard protective gear and smart protective gear. Fabric protective gear is usually made of soft materials, such as cloth, foam or elastic materials, and can wrap different parts of the body, such as the head, arms or legs. Fabric protective gear is light, comfortable and easy to wear. However, the protective performance of fabric protective gear is relatively low, and it cannot provide sufficient protection against heavy pressure, sharp objects or high-speed impact. In addition, fabric protective gear is highly lossy, easy to wear, age and deform, and needs to be replaced regularly. Due to its strong lossiness, the auxiliary characteristics of personalized rehabilitation needs and long-term rehabilitation goals are less satisfied. Hard protective gear is usually made of hard materials, such as plastic, metal or composite materials. Hard protective gear can provide a higher level of protection and is particularly suitable for dangerous environments or high-risk activities. Hard protective gear is commonly used in the fields of sports protective gear, industrial safety equipment, etc. However, hard protective gear may not be comfortable enough and limit the freedom of movement and activity. It is heavy and not suitable for long-term wear, which may cause discomfort or fatigue. Some hard protective gear may require professional customization to ensure the fit, and the applicability and timely adjustment are poor. In addition, the tracking feedback of the rehabilitation effect cannot be identified and the progress cannot be adjusted due to the material and structure. Smart protective gear combines advanced technologies such as sensors, electronic components and data analysis to provide highly personalized protection. They can monitor body posture, physiological signals, environmental conditions, etc., and provide alarms or adjust the performance of the protective gear when necessary. However, smart protective gear is usually more expensive and has high maintenance costs, and may require regular charging or repair. In addition, the dependence on technology may cause users to become overly dependent on the protective gear, reducing their own perception and self-protection capabilities. And the content of the monitorable parameters of most protective gear is relatively limited. Fabric protective gear is suitable for light protection, hard protective gear provides a higher level of protection, and smart protective gear has some advanced functions, but it also comes with more technical and economic costs.
[0031] When sensors are combined with fabrics, more applicable functions can be brought to improve people's quality of life in various fields such as health and sports. Among them, the combination of the sensor and the deformable material can be used to monitor the health of users in real time, for example, monitoring the user's vital signs, such as monitoring heart rate, blood pressure, body temperature and respiratory rate, which helps to monitor chronic diseases for a long time, and even find problems with the user to provide emergency medical assistance to the user. By combining the sensor with the deformable material, the number of steps, calorie consumption, exercise intensity and sleep quality of the user during exercise can also be tracked in real time. It helps to formulate a healthy lifestyle for the user, improve the user's sports performance, and even determine the risk of sports injuries. For example, a football player can wear sportswear equipped with sensors, which can record data such as the football player's running speed, jumping height and kicking strength. The football coach can understand the strengths and room for improvement of the football player based on the acquired data, so that an effective training plan can be specified for the football player. For another example, dancers, actors and performing artists can wear dance clothes or costumes embedded with sensors to record body movements. The instructor can evaluate the performance quality, improve posture and artistic performance based on the acquired body movement data. Specifically, the body posture and dance steps of ballet dancers can be accurately obtained. For example, patients recovering from fractures can wear smart fabrics to monitor the range of motion and strength of their limbs, and rehabilitation doctors can adjust their rehabilitation plans based on these data. In addition, some fabric sensors can also be used to monitor the posture of the elderly in order to prevent falls in a timely manner. Sensors embedded in the fabric can monitor body posture and remind users to maintain the correct posture, which helps reduce discomfort in the neck, back and joints.
[0032] In the related art, the rehabilitation brace can be a power-assist device, and the power-assist device can use a motor as a driver to provide driving force for the power-assist device. However, the motor is heavy and has poor flexibility, which makes the power-assist device less comfortable to wear. Researchers have found that polypyrrole (PPy) is a common conductive polymer. Compared with other conductive polymers, polypyrrole (PPy) has the advantages of easy synthesis, easy film formation, high conductivity, good stability and environmental friendliness. After doping, it has good conductivity, antistatic and corrosion resistance. Therefore, polypyrrole can be used as a conductive material, electrochromic material, medical material, secondary battery anode material, anticorrosive material, antistatic material, and can also be used to prepare sensors, actuators, solid electrolytes and capacitors, etc. It has broad application prospects. Therefore, how to use polypyrrole to make conductive fabrics that deform under different electric fields to manufacture products that assist rehabilitation exercises is extremely urgent.
[0033] In response to the above problems, the embodiments of the present application provide a rehabilitation sports auxiliary protective gear and a rehabilitation system, which have low complexity.
[0034] In an exemplary embodiment, as shown in FIG1 , a rehabilitation exercise assistive brace 10 is used to assist a user in performing rehabilitation exercises. The rehabilitation exercise assistive brace 10 includes a wearable brace body 101, and the wearable brace body 101 includes an extendable or contractible sleeve 1013 composed of a conductive fabric 1011 and a flexible fabric 1012; the rehabilitation exercise assistive brace 10 also includes an electrode group 102 and a signal monitoring and processing device 103, and the signal monitoring and processing device 103 is connected to the electrode group 102 through a first wire 104, and the electrode group 102 is electrically connected to the conductive fabric 1011; the signal monitoring and processing device 103 is used to monitor the rehabilitation exercise monitoring signal when the user performs rehabilitation exercises, and control the conductive fabric 1011 to deform to assist the user in performing rehabilitation exercises.
[0035] Among them, the conductive fabric 1011 is a smart material, and the thickness is designed to be 0.001~5mm in the rehabilitation sports auxiliary protective gear. The conductive fabric can produce physical deformation under the action of voltage or electric field, and has special electrical and mechanical properties. It is similar to a variable capacitor. When the electromyography monitoring sensor and the motion monitoring sensor collect the active motion signal of the human body, the capacitance value is converted into a measurable voltage value through the conversion circuit of the processor. Under electrical stimulation, the conductive fabric realizes elongation and contraction, and assists the human body to complete active movements. The conductive fabric 1011 can be polypyrrole (PPy). Polypyrrole is a common conductive polymer. Compared with other conductive polymers, polypyrrole (PPy) has the advantages of easy synthesis, easy film formation, high conductivity, good stability and environmental friendliness. After doping, it has good conductivity, antistatic and corrosion resistance. Therefore, polypyrrole can be used as a conductive material, electrochromic material, medical material, secondary battery anode material, anticorrosive material, antistatic material, and can also be used to prepare sensors, actuators, solid electrolytes and capacitors, etc., and has broad application prospects.
[0036] The sleeve 1013 may be a fine composite material cloth woven from the conductive fabric 1011 and the flexible fabric 1012, and may have directionally controllable ductility and elasticity, and may be stretchable and shrinkable. The sleeve 1013 may be used on the user's knee joint, ankle joint, shoulder joint, etc. The signal monitoring and processing device may be a device integrating monitoring and processing, and the signal monitoring and processing device may include a monitoring sensor and a processor. After the processor obtains the rehabilitation movement monitoring signal monitored by the monitoring sensor, it processes the rehabilitation movement monitoring signal to obtain the voltage corresponding to the rehabilitation movement monitoring signal. Among them, the monitoring sensor may be an electromyography monitoring sensor and / or a motion monitoring sensor.
[0037] The electrode group may include a plurality of electrodes, and the electrodes may be in a strip shape. The first wire may be a multi-wire bundle wire, for example, a first wire bundle in the first wire may be connected to a first electrode in a group of electrodes, and a second wire bundle in the first wire may be connected to a second electrode in a group of electrodes, that is, the number of wire bundles in the first wire may correspond to the number of electrodes in a group of electrodes, or may not correspond.
[0038] In an embodiment of the present application, when the user uses the rehabilitation exercise assistive protective gear, the sleeve can be inserted into the body joint, and the signal monitoring and processing device can be fitted to the body near the joint, and the user can exercise. The signal monitoring and processing device can monitor the user's rehabilitation exercise monitoring signal by fitting the user's body, obtain the user's exercise intention, and convert the rehabilitation exercise monitoring signal into a voltage. The signal monitoring and processing device is connected to the electrode group through a first wire, and the electrode group is connected to the conductive fabric. Therefore, the signal monitoring and processing device can apply the voltage to the target electrode corresponding to the target harness in the electrode group through the target harness of the first wire according to the user's exercise intention, and the target electrode conducts the voltage to the part of the conductive fabric electrically connected to the target electrode. The part of the conductive fabric can drive the sleeve of the specific area corresponding to the part of the conductive fabric to contract or relax according to voltages of different amplitudes, drive the user's joints to contract or relax, and provide rehabilitation assistance for the user when exercising.
[0039] For example, the user puts the sleeve on the knee joint, the signal monitoring and processing device is located at the thigh and / or calf of the knee joint, and the user extends the knee. The signal monitoring and processing device monitors the rehabilitation movement monitoring signal at the thigh and / or calf, obtains the user's movement intention as knee extension according to the rehabilitation movement monitoring signal, and converts the rehabilitation movement monitoring signal into voltage. The signal monitoring and processing device is connected to the electrode group through the first wire, and the electrode group is connected to the conductive fabric. Therefore, the signal monitoring and processing device can apply the voltage to the target electrode corresponding to the target harness in the electrode group through the target harness of the first wire according to the user's movement intention to extend the knee. The target electrode is an electrode connected to the sleeve of the front part of the knee joint. The target electrode conducts the voltage to the part of the conductive fabric corresponding to the part of the sleeve, so that the part of the conductive fabric can drive the part of the sleeve to contract in the direction of knee extension according to the voltage, and assist the user to extend the knee. At this time, the other parts of the conductive fabric do not contract or relax because they do not receive the voltage. As shown in Figure 2, the conductive fabric in the lower half of the dotted line does not receive the voltage, and the lower half is relaxed.
[0040] The above-mentioned rehabilitation exercise auxiliary protective gear is used to assist users in performing rehabilitation exercises, and the rehabilitation exercise auxiliary protective gear includes a wearable protective gear body, and the wearable protective gear body includes an extendable or contractible sleeve composed of a conductive fabric and a flexible fabric; the rehabilitation exercise auxiliary protective gear also includes an electrode group and a signal monitoring and processing device, and the signal monitoring and processing device is connected to the electrode group through a first wire, and the electrode group is electrically connected to the conductive fabric; the signal monitoring and processing device is used to monitor the rehabilitation exercise monitoring signal when the user performs rehabilitation exercises, and control the conductive fabric to deform to assist the user in performing rehabilitation exercises. In the rehabilitation exercise auxiliary protective gear provided in the embodiment of the present application, there is provided a product for manufacturing auxiliary rehabilitation exercises using polypyrrole to make conductive fabrics that deform under different electric field conditions, wherein the signal monitoring and processing device monitors the user's rehabilitation exercise monitoring signal, obtains the user's exercise intention, and converts the rehabilitation exercise monitoring signal into a voltage. The signal monitoring and processing device applies the voltage to the electrode group through the first wire according to the user's exercise intention, and the electrode group applies the voltage to the conductive fabric. The conductive fabric can drive the sleeve in a specific area corresponding to the conductive fabric to contract or relax according to voltages of different amplitudes, thereby driving the user's joints to contract or relax, providing rehabilitation assistance to the user during exercise, with low complexity of use.
[0041] In an exemplary embodiment, the rehabilitation movement monitoring signal includes a surface electromyography signal, and the signal monitoring and processing device includes at least one group of electromyography monitoring sensors and a first processor, and the electromyography monitoring sensors and the first processor are connected via a second wire.
[0042] In an embodiment of the present application, the signal monitoring and processing device may be a device integrating an electromyographic monitoring sensor and a first processor.

The electromyographic monitoring sensor and the first processor are connected via a second wire, and the electromyographic monitoring sensor transmits the obtained surface electromyographic signals to the first processor via the second wire, so that the first processor can convert the surface electromyographic signals into voltage.
[0043] Optionally, there are two groups of electromyographic monitoring sensors, in which case there may also be two first processors and second wires. The first group of electromyographic monitoring sensors is located at the user's thigh, and the second group of electromyographic monitoring sensors is located at the user's calf. The user puts the sleeve on the knee joint and performs knee extension exercises. The first group of electromyographic monitoring sensors monitors a first surface electromyographic signal at the user's thigh, and the second group of electromyographic monitoring sensors monitors a second surface electromyographic signal at the user's calf. The first group of electromyographic monitoring sensors transmits the first surface electromyographic signal to the first processor via the second wire, and the first processor converts the first surface electromyographic signal into a voltage. The second group of electromyographic monitoring sensors transmits the second surface electromyographic signal to the second processor via the second wire, and the second processor converts the second surface electromyographic signal into a voltage.
[0044] In an exemplary embodiment, the rehabilitation movement monitoring signal includes a movement monitoring signal, and the signal monitoring and processing device includes at least one group of movement monitoring sensors and a second processor, and the movement monitoring sensor and the second processor are connected via a third wire.
[0045] Among them, the motion monitoring sensor may include an acceleration sensor, an angular velocity sensor, and a magnetic field sensor.
[0046] In an embodiment of the present application, the signal monitoring and processing device may be a device integrating a motion monitoring sensor and a second processor. The signal monitoring and processing device includes at least one group of motion monitoring sensors and a second processor, and the motion monitoring sensor is used to obtain a motion monitoring signal. The motion monitoring sensor and the second processor are connected via a third wire, and the motion monitoring sensor transmits the acquired motion monitoring signal to the second processor via the third wire, so that the second processor can convert the motion monitoring signal into a voltage.
[0047] Optionally, there are two groups of motion monitoring sensors, in which case there may also be two second processors and third wires. The first group of motion monitoring sensors is located at the user's thigh, and the second group of motion monitoring sensors is located at the user's calf. The user inserts the sleeve at the knee joint and performs knee extension exercises. The first group of motion monitoring sensors monitors a first motion monitoring signal at the user's thigh, and the second group of motion monitoring sensors monitors a second motion monitoring signal at the user's calf. The first group of motion monitoring sensors transmits the first motion monitoring signal to the second processor via the third wire, and the second processor converts the first motion monitoring signal into a voltage. The second group of motion monitoring sensors transmits the second motion monitoring signal to the second processor via the third wire, and the second processor converts the second motion monitoring signal into a voltage.
[0048] In an exemplary embodiment, as shown in FIG. 2 , the electrode group includes at least two groups of electrodes, and the at least two groups of electrodes are independently disposed at two ends of the sleeve.

There are two groups of motion monitoring sensors, the first group of motion monitoring sensors are located at the user's thigh, and the second group of motion monitoring sensors are located at the user's calf. The first group of electrodes can be located on the thigh side corresponding to the sleeve, and the second group of electrodes can be located on the calf side corresponding to the sleeve. The user extends the knee, and the signal monitoring and processing device obtains the surface electromyography signal and motion monitoring signal of the user's thigh. The signal monitoring and processing device also obtains the surface electromyography signal and motion monitoring signal of the user's calf, and judges the user's movement intention as extending the knee based on the above signals.

When the human body is doing knee flexion or extension exercises, the electromyographic signals collected by the electromyographic monitoring sensor attached to the upper side of the leg and the electromyographic monitoring sensor on the lower side, as well as the signals collected by the motion monitoring sensor are completely different, so different voltages can be output according to the signal recognition results.

[0051] In this embodiment, the electrode is in a strip shape, which can provide a larger electrode surface area, thereby increasing the efficiency and speed of the reaction. Therefore, using the strip electrode for signal transmission can improve the efficiency of contraction or relaxation of the rehabilitation sports auxiliary support device.
[0052] Optionally, the conductive fabric is woven from a plurality of conductive fibers.
[0053] In one embodiment, as shown in FIG. 3 , the rehabilitation system 30 includes the above-mentioned rehabilitation exercise assistive brace.
