As shown in fig. 1, the knee brace includes a first binding assembly, a second binding assembly, and a detection assembly. Wherein, first binding assembly includes first binding belt 1 and first attached board 2, and in this embodiment, the quantity of first binding belt 1 is two, and the interval is fixed on first attached board 2, through setting up two first binding belts 1, can further ensure the laminating effect of first attached board 2 and human thigh. Specifically, the first binding band 1 is fixed on the first binding seat, and the first binding seat is fixed on the first attaching plate 2, helping to protect the fixing effect of the first binding band 1 by providing the first binding seat. Meanwhile, the number of the first attaching plates 2 is two, and when the first binding band 1 is fixed on the thigh of the human body, the two first attaching plates 2 are respectively located at both sides of the thigh of the human body.
At this time, the second binding assembly includes the second binding belt 3 and the second attaching plate 4, and accordingly, the setting mode of the second binding assembly may refer to the setting mode of the first binding assembly, so as to ensure the binding effect of the knee joint supporter on the thigh and the calf of the human body. Simultaneously, all be provided with the protection pad on first binding seat and the second binding seat, the protection pad's that is provided with helps improving the fixed effect that first binding subassembly and second binding subassembly.
In the above specific embodiment, the detection assembly includes the first detection member 5, the second detection member 6, the processor, the power supply, and the control switch. Wherein the first detecting member 5 is used for detecting the muscle moment of the knee joint of the patient when the knee joint is bent and stretched at a fixed angle, and the second detecting member 6 is used for detecting the included angle between the thigh and the calf of the human body. According to the application, the action information of the patient in the movement process is obtained by detecting the muscle moment and the included angle between the thigh and the calf, so that the rehabilitation condition of the patient is determined, and reference data is provided for the subsequent rehabilitation training of the patient.
Specifically, the first detecting element 5 is a torque sensor, and the first attaching plate 2 and the second attaching plate 4 are hinged by the torque sensor. Because the moment sensor has a power end and a load end, in this embodiment, the power end of the moment sensor is fixedly connected with one of the first attaching plate 2 or the second attaching plate 4, and correspondingly, the load end of the moment sensor is fixedly connected with one of the second attaching plate 4 or the first attaching plate 2, so that the muscle moment of the knee joint of the patient during bending and stretching at a fixed angle can be effectively detected by matching the fixation of the first binding assembly and the second binding assembly.
Because the existing muscle moment detection equipment is large in size, and corresponding technicians need to be found for detection during detection, the detection difficulty is increased, and the detection cost is increased. According to the application, the moment sensor is arranged at the hinge joint of the first attaching plate 2 and the second attaching plate 4 and is positioned at two sides of the knee joint, so that the detection difficulty of the muscle moment is simplified, the muscle moment of a patient can be detected at any time, the moment sensor can be used as a connecting device of the first attaching plate 2 and the second attaching plate 4, the fixing and the protection of the knee joint support on the knee joint are realized, and the use effect of the knee joint support is ensured.
In this case, the second detecting member 6 is two inertial sensors, and for convenience of description, one of the two inertial sensors is referred to as a first inertial sensor, and the other of the two inertial sensors is referred to as a second inertial sensor. The first inertial sensor is arranged on the first binder 1 of the first binder assembly and the second inertial sensor is arranged on the second binder 3 of the second binder assembly. In this embodiment, when the knee joint brace is fixed to a human body, the first binding assembly is fixed to a thigh of the human body, the second binding assembly is fixed to a calf of the human body, and at this time, the first inertial sensor is located in front of the thigh of the human body. The second inertial sensor is located in front of the human calf, so arranged that the first inertial sensor and the second inertial sensor can cooperate with each other, thereby detecting an included angle between the human thigh and the human calf. Because the inertial sensor product is mature, the inertial sensor can be directly purchased and used, and the existing inertial sensor is small in size and light in weight, and is fixed on the first binding belt 1 or the second binding belt 3, the detection purpose can be achieved, and the influence on the weight of the knee joint brace can be reduced, so that the wearing effect of the knee joint brace is guaranteed.
Here, the second detecting member may employ other sensors to be able to detect the angle between the thigh and the calf of the human body. However, because this knee joint brace is used for wearing at human shank, adopts inertial sensor can ensure the weight of knee joint brace, ensures the travelling comfort of wearing for this knee joint brace possesses better detection and wearing effect.
In addition, the detection assembly further comprises a processor, a power supply and a control switch. Wherein, the processor is electrically connected with first detecting element 5 and second detecting element 6, and the processor is used for outwards transmitting the data detected by first detecting element 5 and second detecting element 6. Simultaneously, power supply and control switch all are connected with the treater electricity, and control switch is used for controlling the start-up of treater, first detection piece 5 and second detection piece 6. Because the doctor is not needed to assist in most of the time of rehabilitation training of the patient, and when rehabilitation detection is carried out, the doctor does not need to assist in detection at the patient, therefore, through the arrangement of the processor, the processor can directly transmit detection data to external equipment, the patient can be not required to record the detection data, the detection flow of the rehabilitation effect is facilitated to be simplified, the detection efficiency is improved, and the detection accuracy is guaranteed. Meanwhile, by arranging the control switch and the power supply, the patient can detect the rehabilitation condition of the knee joint at any time and any place, thereby being beneficial to reducing the influence of environmental factors on the detection time and the detection effect and improving the convenience of knee joint detection.
Specifically, the processor comprises an information processing module, a transmission module and a charging module. The information processing module is used for collecting data and processing the collected data. Because the inertial sensor is a sensor for detecting and measuring acceleration, inclination, impact, vibration, rotation and multi-degree-of-freedom motion, the angle between the thigh and the calf of the human body cannot be directly detected, and the detected data is required to be arranged and analyzed, the application enables the processor to be arranged and analyzed on the data of the first detection piece 5 and the second detection piece 6 by arranging the information processing module, and finally obtains more visual detection results. Meanwhile, the transmission module is used for transmitting the collected and processed data outwards so as to ensure the information transmission performance of the processor, and the charging module is arranged so as to charge a power supply, thereby further guaranteeing the use effect of the knee joint brace and prolonging the service life of the knee joint brace.
Here, it should be noted that the above processor may further include a storage module to ensure the detection data of the first detection element 5 and the second detection element 6, so as to provide a storage basis for the processing of the data and ensure the subsequent comparative analysis.
In the present embodiment, each of the inertial sensors is configured with a processor, a power supply, and a control switch corresponding thereto, and at this time, the inertial sensors, the processor, the power supply, and the control switch are combined into one detection device. The detecting device is detachably provided on the first binding band 1 or the second binding band 3. Meanwhile, the moment sensor is electrically connected with one of the detection devices, and the detection device can receive detection data of the moment sensor and transmit the detection data outwards. The arrangement can reduce the influence on the protection and fixing effects of the knee joint brace, and can also ensure the whole weight of the knee joint brace and improve the use effect of the knee joint.
The embodiment also relates to a detection system after knee joint operation, which comprises the knee joint support, a first terminal and a second terminal.
The knee joint brace can detect muscle moment of the knee joint of a patient when the knee joint of the patient bends and stretches at a fixed angle and detect an included angle between the thigh and the calf of the human body, so that action information of the patient during movement can be acquired and the movement information is transmitted outwards. Meanwhile, the first terminal and the second terminal can both receive the detection data transmitted by the detection component, and the second terminal can send a rehabilitation scheme to the first terminal.
As shown in fig. 2, the detection system includes a knee brace, a first terminal, a second terminal, and a cloud detection server. Wherein the knee joint brace is capable of being worn on a leg of a patient. The cloud detection server is in communication connection with the first terminal and the second terminal. In this embodiment, the first terminal is a patient end, the second terminal is a doctor end, and the patient end and the doctor end may be a computer or a mobile phone. The first terminal and the second terminal are in communication connection with the cloud detection server through a software program. When in actual use, the doctor mobile phone end can generate or edit the rehabilitation scheme of the patient, send the rehabilitation scheme to the patient, then carry out rehabilitation training according to the rehabilitation scheme by the patient, and detect the rehabilitation effect at regular time.
In this embodiment, the first terminal is communicatively coupled to the detection assembly of the knee brace. When the patient needs to detect the rehabilitation effect of the knee joint, the patient needs to start the detection assembly through the control button, then the first terminal is connected with the detection assembly through Bluetooth, and then the patient needs to detect according to the requirements of the rehabilitation scheme and the detection scheme provided by the patient. In the detection process, the moment sensor can transmit detection data to one of the first inertial sensor and the second inertial sensor, the first inertial sensor and the second inertial sensor can transmit detection results to the first terminal, at the moment, the first terminal transmits the detection data to the cloud detection server through software, the detection data can appear on a doctor using terminal, meanwhile, the cloud detection server can send a rehabilitation scheme to the doctor using terminal according to the detection results, then the doctor can adaptively adjust the rehabilitation scheme according to actual rehabilitation training conditions of a patient, and finally the doctor using terminal sends a final rehabilitation scheme to the patient using terminal.
According to the detection system for the knee joint postoperative, the first terminal and the second terminal are arranged to be matched with the knee joint brace, so that the recovery condition of the knee joint can be detected timely, a doctor can modify or perfect a detection scheme according to a detection result at the first time, and finally follow-up recovery training content of a patient is determined, so that the doctor can know the recovery effect of the knee joint of the patient, the recovery effect of the patient is improved, and the patient can recover an original movement function as soon as possible.
In addition, the present embodiment further relates to a method for detecting a knee joint after operation, which is implemented according to the above detection system for detecting a knee joint after operation, as shown in fig. 3, and the detection method includes:
basic information of a patient is acquired, and a knee joint rehabilitation database is established;
acquiring the angle and the muscle moment of the knee joint of the patient during flexion and extension;
based on a knee joint rehabilitation database, and according to the fact that the angle and the muscle moment do not meet rehabilitation training requirements, a corresponding rehabilitation scheme is formulated;
obtaining the actual rehabilitation situation of the patient, modifying or perfecting the rehabilitation scheme, and sending the rehabilitation scheme to the patient.
Specifically, the detection method firstly establishes a knee joint rehabilitation database. The knee joint rehabilitation database needs to be established by collecting various knee joint injuries and treatment cases in advance and corresponding rehabilitation schemes and processes. In this embodiment, the number of cases collected in the knee joint rehabilitation database is at least 3000, so that an objective database can be formed perfectly, and the database can be improved and enriched according to the existing cases. Meanwhile, basic information of the patient needs to be acquired, including data such as the damage condition of the knee joint, the operation type and the operation effect, so as to provide a theoretical basis for the proposal of a follow-up rehabilitation scheme.
Then, the knee joint of the patient is detected through the knee joint brace, and the angle and the muscle moment of the knee joint during bending and stretching are obtained, so that the movement data of the patient are recorded, and at the moment, the detection result is uploaded through communication connection, so that the detection result is compared with a knee joint rehabilitation database.
When the angle and the muscle moment of the knee joint during detection do not meet the rehabilitation training requirements, the cloud detection server can formulate a corresponding rehabilitation scheme and send the rehabilitation scheme to a doctor using terminal. At this time, the doctor can determine whether the rehabilitation scheme can be performed through communication with the patient and the family members, if not, the doctor can adaptively adjust the rehabilitation scheme, and if so, the doctor can directly send the rehabilitation scheme to the patient using terminal and prompt the doctor to train according to the rehabilitation scheme.
When the angle and the muscle moment of the knee joint during detection meet the rehabilitation training requirements, the cloud detection server can give a prompt meeting the rehabilitation training standards, and at the moment, the cloud detection server can send a subsequent training scheme or a subsequent training process of the original scheme to the doctor using terminal. The rehabilitation regimen is then sent to the patient use terminal after the physician's consent and via the physician use terminal.
After the patient finishes the rehabilitation training of the next stage, the subsequent rehabilitation effect detection is carried out, and the treatment is carried out according to the flow until the patient is determined to finish the complete rehabilitation.
As shown in fig. 4, after obtaining basic information of a patient, the method includes:
based on the knee joint rehabilitation database, formulating a pre-rehabilitation scheme and sending the pre-rehabilitation scheme to a patient;
after rehabilitation training is completed according to the early rehabilitation scheme, the angle and the muscle moment of the knee joint of the patient during flexion and extension are detected.
Because the patient can not judge the rehabilitation effect of the knee joint after operation, a front rehabilitation scheme needs to be formulated first, and the patient can detect the rehabilitation training effect of the knee joint after rehabilitation training according to the front rehabilitation scheme. Therefore, after the operation of the patient, it is necessary to determine a pre-rehabilitation scheme based on the knee joint rehabilitation database and basic information of the patient, such as the injury condition of the knee joint, the operation content and the operation effect, and then transmit the pre-rehabilitation scheme to the patient after the determination by the doctor, and then detect the angle and the muscle moment of the knee joint of the patient when bending and stretching after the patient performs rehabilitation training according to the pre-rehabilitation scheme for a period of treatment.
The detection method for the knee joint after operation can detect the postoperative rehabilitation of the knee joint in a staged mode, so that continuous and correct rehabilitation treatment can be guaranteed for patients, symptoms can be improved, disease development can be delayed, disease control effect is improved, and rehabilitation curative effect is promoted. The detection method of the application can improve the detection efficiency, reduce the need of rehabilitation talents and ensure the correct performance of rehabilitation training through the detection system after knee joint operation.
The present application is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present application are intended to be included in the scope of the present application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
