Detailed Description

Referring to fig. 1, a wisdom orthopedics joint rehabilitation monitoring system, including intelligent knee-pad, mobile terminal and high in the clouds server, this intelligence knee-pad mainly includes: a knee pad main body 1 for mounting on a knee of a user; the gyroscope is used for monitoring the walking steps of the user; the angle sensor 2 is used for monitoring the knee bending degree of the user in real time; the temperature sensor is used for monitoring the temperature of the wound of the user in real time; the data transmission module 6 is used for transmitting the measured data to the mobile terminal in real time;

Regarding the temperature sensor: the temperature of the wound needs to be monitored in real time after the joint operation, whether the wound is in a proper temperature environment or not can be judged, and the method can also be used as an important basis for judging whether the wound is inflamed or not, so that the possibility of infection caused by overhigh temperature is reduced. Because the wound is easy to be infected by contact, a non-contact temperature sensor is selected, and a sensitive element of the non-contact temperature sensor is not contacted with a measured object, so that the probability of infection of the wound is reduced. For automatic measurement and control of wound surface temperature, additional mirrors may be used to form the hohlraum with the surface being measured. The effect of the additional radiation can increase the effective radiation and the effective emissivity of the surface to be measured. And correspondingly correcting the measured temperature by using the effective emission coefficient through an instrument to finally obtain the real temperature of the measured surface.

With regard to the gyroscope: the electronic gyroscope is used for monitoring the walking steps of the user, the angular rate applied to the input part of the gyroscope is converted into an electric parameter which can be detected by a special circuit, the electric parameter can calculate the offset, and the step number of the patient is obtained and stored by recording the offset of each time.

With respect to the angle sensor 2: the magnetic-sensing angle sensor is placed on the knee pad part corresponding to the knee joint side position and used for monitoring the knee bending degree of a patient in real time and making a real-time judgment on the recovery state of the patient by matching with a doctor. In order to ensure the safety of the movement of the patient, a buckle 4 which can be manually regulated and controlled is added in the U-shaped groove 3 for transmitting the movement of the lower leg, so as to limit the maximum knee bending angle of the patient and prevent the secondary damage caused by excessive movement. The angle sensor 2 is used for being installed on the knee-pad main body 1 corresponding to the lateral position of the knee joint, and the knee-pad main body 1 is further provided with a limiting mechanism for limiting the maximum knee bending angle of a user. The limiting mechanism is a buckle 4 mounted on a rotation connecting portion on the lower portion of the knee pad body 1, and the relative position of the buckle 4 on the knee pad body 1 can be adjusted. Meanwhile, the upper part of the main body 1 is provided with a limiting part 5, the limiting part 5 is limited to slide only in the U-shaped groove 3, and therefore the position of the buckle 4 limits the maximum displacement angle of the limiting part 5, and the maximum knee bending degree of a patient is limited.

The temperature sensor, the gyroscope and the angle sensor are internally provided with the low-power-consumption Bluetooth module supporting the IIC interface, and are mainly responsible for acquiring sensor data through the communication interface, transmitting processed or received digital data through the BLE interface and monitoring the digital data through a mobile phone or any other client equipment with a built-in BLE function. And calling a bottom layer program by the mobile phone terminal, compiling and reading a serial port program, converting the received data into a decimal system according to the sent protocol, and displaying the decimal system on the mobile phone APP.

Among global interactions, there are four principals that coexist: the intelligent kneepad comprises a user, an intelligent kneepad, a mobile terminal and a cloud server, wherein the interaction between the user and the mobile terminal is called man-machine interaction; in the mobile terminal, the APP relies on the mobile phone to generate service, and in the cloud terminal, the server, the database and the background form cloud terminal service. The user wears intelligent knee-pad, intelligent knee-pad passes through digital temperature sensor, angle sensor, the detailed data of patient's joint is collected to the micromechanical gyroscope, with body temperature data, bend knee degree data, walk data and pass through in the bluetooth uploads to the cell-phone, these data of joint language APP record and temporary storage are in the middle of local, the another side, the user uses painful sense quantization table to obtain the pain index every day, reuse APP types into in the cell-phone, APP regularly transmits data to the storage in the server high in the clouds database every day, thereby realized data collection and data upload function. On the other hand, when the user wants to acquire the monitoring data of the user, the joint speaks to firstly call the basic data (including wound temperature, walking time and distance and knee bending degree) stored in the local area, secondly, the joint speaks to send a query request to the cloud end, the cloud end processes the request and re-encodes the request and forwards the request to the database for query, and the data is analyzed intelligently through the background to obtain a deep analysis report and is downloaded to the mobile terminal, so that the data is acquired by the user. Therefore, a complete human-computer interaction path is completed, data are returned to the mobile terminal after collection, storage, inquiry and utilization and are read by a user, and real global interaction is achieved.

In a traditional self-locking mechanism, for example, a chinese patent publication No. CN107714259A, an intelligent control device is often used to detect a motion state, and when an abnormal condition is detected, a signal is sent to drive a motor to lock the knee pad angle. In such a mode, because the electric control has delay and hysteresis and the failure rate is high, when the electric control has hysteresis or failure, the electric control cannot work effectively, and hidden danger exists.

Therefore, another improved embodiment of the scheme is provided, when a patient falls, the knee pad can be locked by the patient, and the triggering is not required to be realized through electric control.

The specific scheme is as follows: a detection bin 7 is arranged in the main body of the kneepad, a movable steel ball 8 is arranged in the

detection bin

7, 5 stagnation areas for the steel ball 8 to stay are arranged in the detection bin 7, and the horizontal height of one stagnation area (a first stagnation area 9) is lower than that of the rest stagnation areas. The rest stagnation areas (4 second stagnation areas 10) are distributed at the front, the back, the left and the right of the detection bin 7 and are at the same horizontal height. Between the various stagnation zones, curved guide transitions 11 are provided, by means of which setting it is facilitated that the steel balls 8 can quickly fall into the different stagnation zones. Magnetic parts 12 for adsorbing the steel balls 8 are arranged on the 4 second stagnation areas 10, a group of contact pieces 13 are arranged at the second stagnation areas 10, and when the steel balls 8 are adsorbed, the steel balls 8 are communicated with the group of contact pieces 13. In the actual use process, when a patient wears the intelligent knee pad, when the patient falls down, the steel ball 8 rolls from the first stagnation area 9 to one of the second stagnation areas 10, and particularly, which position needs to be determined according to the inclination direction of the patient, so that the second stagnation areas 10 at four circumferential positions are arranged to ensure no error.

The main body of the knee pad comprises a lower leg support 14 and a thigh support 15 which are rotatably arranged with each other, an electromagnet assembly 16 is arranged inside the upper thigh support 15, and a movable block 17 slidably arranged on the inside of the thigh support 15, and a locking lever 18 is arranged on the movable block 17. A gear 21 is arranged at the top of the shank support 14, when the steel ball 8 is connected with the contact piece 13 on the second stagnation area 10, the internal circuit is connected, the electromagnet assembly 16 is triggered to start working, the movable block 17 is attracted downwards, the locking rod 18 is clamped on the gear 21, and therefore the shank support 14 and the thigh support 15 are locked. At this time, even if the patient falls down, the injured knee joint is protected. The circuits formed by the contact among the contact sheets 13 are connected in parallel, so that the internal circuit can work after the contact sheet 13 of any one second stagnation area 10 is connected, and the electromagnet can obtain magnetic force.

In order to facilitate the return of the mechanism, a forced-release mechanism 19 is further provided in the detection chamber 7, and the steel ball 8 is removed from the second stagnation section 10 by the forced-release mechanism 19. Thus, the circuit is cut off, and the electromagnet does not work any more. In order to make the movable block 17 automatically drive the locking lever 18 to release the locking with the gear 21 after not being attracted by the electromagnet, a tension spring 20 is further provided at the lower leg link 14 to pull the movable block 17 upward away from the gear 21. Wherein, the above-mentioned forced disengaging mechanism 19 is specifically: the cross push rod 191 can move up and down in the detection bin 7, the inclined blocks 192 are arranged on four extending rods of the cross push rod 191, the corresponding inclined blocks 192 are placed in the related second stagnation areas 10, the cross push rod 191 is pushed downwards to enable the steel balls 8 to be separated from the adsorption, and therefore the steel balls fall into the first stagnation areas 9 again. The upper center of the cross push rod 191 is connected with a connecting rod, the connecting rod is partially arranged outside the detection chamber 7, the end of the section of connecting rod is provided with a button 193, meanwhile, the cross push rod 191 is iron, and the top wall of the detection chamber 7 is provided with magnetism for adsorbing the cross push rod 191. So configured, the user can press the button 193 to activate the operation of the strong release mechanism 19 when standing is complete or no locking is required.
