Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a novel knee joint orthosis and exerciser device. Background Art

[0002] A knee joint orthosis generally includes an upper leg guard and a lower leg guard, which are installed together by means of a hinge, and are respectively fastened to the patient's thigh and calf through fixed cloth bags. The patient can fix the upper leg guard and the lower leg guard together through relevant mechanisms, which provide support, correction and fixation for the patient's calf, thigh, etc. (for example, it plays the role of plaster fixation when a fracture occurs in the corresponding part), and can also exercise the knee joint when the patient's calf moves back and forth.

[0003] The authorized patent of my country with patent number "201822182878.8" and patent name "knee orthosis" records that "it can effectively improve the stability of work". As can be seen from the above, although the comparative patent has achieved the technical effect of the invention described in it, it is limited by structure and function. When using equipment to exercise the knee part, it depends entirely on the patient's self-behavior. That is to say, for example, if it is applied to hospital departments, if the patient does not take the initiative to exercise, then medical staff need to manually remind the patient to exercise. The above method will bring inconvenience to medical staff, and it cannot be guaranteed that medical staff can remind patients to exercise on time, which is not conducive to the patient's recovery. In addition, when medical staff are not on site, they cannot understand the patient's exercise intensity, which is not conducive to the recovery of patients' knee joint diseases (the lower leg has a large range of motion along the knee joint, so the exercise intensity is relatively large, and vice versa). In summary, it is particularly necessary to provide a device that not only has the function of fixed correction and exercise, but also can understand whether the patient is exercising and the intensity of exercise when medical staff are not on site. Utility Model Content

[0004] In order to overcome the drawbacks of existing knee orthoses due to structural limitations as described in the background, the utility model provides a new type of knee orthosis and exerciser device based on the knee orthosis body. Under the joint action of relevant mechanisms, when the medical staff is not on site, it can understand in real time whether the patient is in an exercise state and the intensity of the knee exercise, thereby bringing convenience to both the patient and the medical staff, and correspondingly improving the effect of the patient's knee disease and other recovery as soon as possible.

The two connecting plates A1012 are adjusted upward or downward along both sides of the lower end of the upper leg guard 101 and fixed by bolts and nuts. The height of the upper leg guard can be adjusted high or low according to the needs of different patients, so that the hinged part between the upper and lower leg guards is located as much as possible in the middle of the outer end of the patient's knee joint) Pass through the fixing hole 1014 and the positioning hole 1013 and fix with nuts; the lower end of the left upper leg guard 101 and the upper end of the left lower leg guard 102 are hinged and installed together, and a circular metal fixing plate 1016 is welded to the lower end of the right upper leg guard 101, and a shaft rod 1017 is horizontally welded to the middle part of the fixing plate 1016, and an annular hollow insulating plastic plate 1018 is glued to the right end of the fixing plate 1016, and an annular hollow resistor RP is glued to the right side of the plastic plate 1018 (the wire connected to the left side of the resistor RP is led upward through the upper part between the resistor RP and the plastic plate 1018), and the resistance surface of the resistor RP is located on the right side; the upper part of the connecting plate of the right lower leg guard is welded A circular metal hollow movable plate 1022 is connected, a circular hollow insulating plastic plate A1023 is glued to the left side of the movable plate 1022, a spring sheet 1024 is hot-melt glued to the left end of the plastic plate A1023, and a wire with a length surplus connected to the right end of the spring sheet 1024 is led out through an opening on the right end of the plastic plate A1023, the plastic plate A1023 and the movable plate 1022 are rotatably sleeved on the outside of the shaft 1017, and a limiting nut 1019 is threadedly installed on the right end of the shaft 1017; the battery G1, the power switch S1, the charging socket C1, and the data sending circuit 2 are installed on the circuit board in the component box 3, and the component box 3 is installed on the left outer end of the upper leg guard 101.

[0017] Figure 1 , 2As shown in the figure, the inner diameter of the hollow part of the resistor sheet RP, the insulating plastic plate 1018, the movable plate 1022, and the hollow insulating plastic plate A1024 is 0.1 mm larger than the outer diameter of the shaft 1017, and the left end of the copper spring sheet 1024 is in sliding electrical contact with the outer end of the resistor sheet RP. The rear sides of the upper leg guard 101 and the lower leg guard 102 respectively conform to the shape of the thigh and calf of the human body, and the connecting plate 1021 of the lower leg guard and the connecting plate A1012 of the upper leg guard are respectively located on both sides of the human leg and are spaced a certain distance from the two outer sides of the leg. A positioning plate 1020 is vertically welded to the middle of the lower end of the fixed plate, and a screw hole is provided in the middle of the lower end of the positioning plate 1020. A positioning plate A1025 is vertically welded to the middle of the lower end of the movable plate, and an opening is provided in the middle of the lower end of the positioning plate A1025. A bolt A1026 is screwed into the screw hole of the positioning plate 1020 through the opening of the positioning plate A1025, and the positioning plate 102 and the lower end of the positioning plate A1025 are fixedly installed together. The left rear end of the upper leg guard 101 and the lower leg guard 102 has two rectangular buckles 4 with fixing grooves from top to bottom, and the right rear end of the upper leg guard and the lower leg guard has two rectangular fixing holes 5 from top to bottom, and each fixing hole 5 is sewn and fixed with a step quality strap (not shown in the figure), and the four straps are respectively wrapped around the four buckles 4 and fixed with buckles. The data transmission circuit includes a resistor R1 and a WiFi data transmitting module W1 connected by a wire, and the signal input terminal 3 pin of the WiFi data transmitting module W1 is connected to one end of the resistor R1. The two poles of the battery G1 and the two ends of the charging socket C1 (the socket is located outside the first opening at the upper end of the component box) are connected via wires, and are connected in series via the power switch S1 (the handle is located outside the second opening at the upper end of the component box) and the 1st and 2nd pins of the power input terminal WiFi data transmission module W1 of the data sending circuit are connected via wires, the positive pole of the battery G1 and the right outer side of the spring sheet 1024 are connected via a wire, and the resistor RP and the 3rd pin of the signal input terminal WiFi data transmission module W1 of the data sending circuit are connected via a wire.

[0018] Figure 1 , 2As shown in the figure, when the present invention is used, the upper leg guard 101 and the lower leg guard 102 are respectively tied to the thigh and lower leg of the person through the straps (the straps are located at the back of the thigh and the calf, and this technical point is a mature application technology), and the upper leg guard 101 and the lower leg guard 102 are located between the knees of the person. When the bolt A1026 is loosened, the patient can move the calf forward and backward, thereby exercising the calf and thigh, and especially the knee (for example, playing a role in treating knee joint diseases, etc.). When the bolt A1026 is fixed (the bolt A1026 is screwed into the screw hole of the positioning plate 1020 through the opening of the positioning plate A1025, and the positioning plate 102 and the lower end of the positioning plate A1025 are fixedly installed together), since the upper leg guard 101 and the lower leg guard 102 are fixed, the two no longer rotate along the hinge point, and can play a role in orthopedic fixation of the patient's knees and other parts. When not in use, the present invention can be removed by loosening the straps. When the patient unscrews the bolt A1026, the lower ends of the positioning plates 1020 and A1025 are no longer fixed together, so that the lower end of the left upper leg guard 101 and the upper end of the left lower leg guard 102 can rotate freely forward and backward at the hinged parts, and the right upper leg guard 101 can rotate freely forward and backward along the outer side of the shaft 1017 through the plastic plate A1023 and the movable plate 1022, which has a good exercise effect on the patient's knee joint. In the present invention, after turning on the power switch S1, the data transmission circuit is powered on and works, and the positive power of the battery G1 enters one end of the resistor R1 and the 3rd pin of the WiFi data transmission module W1 through the resistor RP and the copper spring sheet 1024. When the patient's calf moves forward along the knee joint, the spring sheet 1024 moves counterclockwise along the resistor RP. In this way, the power output of the battery G1 enters one end of the resistor R1 through the resistor RP (the resistance is high at this moment) and the spring sheet 1024. The voltage signal is relatively low. When the patient's calf moves backward along the knee joint, the spring sheet 1024 moves clockwise along the resistor RP. In this way, the power output of the battery G1 enters one end of the resistor R1 through the resistor RP (the resistance is low at this moment) and the spring sheet 1024. The voltage signal is relatively high. Through the above, when the arc of the patient's calf moving forward or backward is relatively small, the voltage signal entering one end of the resistor R1 will be relatively high or relatively low. When the arc of the patient's calf moving forward or backward is relatively large, the voltage signal entering one end of the resistor R1 will be relatively lower or relatively higher.The power signal output to one end of the resistor R1 as the patient's leg moves enters pin 3 of the WiFi data transmitting module W1 after voltage division by the resistor RP and the resistor R1. The WiFi data transmitting module W1, under the action of its internal circuit, transmits the input dynamically changing voltage signal wirelessly through the existing extremely mature WiFi data transmitting module technology. Medical staff receive and display data through the WiFi data receiving module of relevant intelligent devices (such as smart phones or PCs). When the relevant medical staff are not on site, they can understand in real time whether the patient is in an exercise state and the intensity of the knee exercise, thereby bringing convenience to both the patient and the medical staff, and correspondingly improving the effect of the patient's knee disease recovery as soon as possible (the voltage signal does not change when the patient exercises, which means that the patient has not performed calf activities. The voltage signal changes from low to high with a small degree and a fast frequency, which means that the patient has a low level of exercise, and vice versa). It should be noted that the WiFi data transmitting module W1 sends data, and the smart device receives and displays data via the WiFi data receiving module, which is an extremely mature technology. This application does not provide any protection for the above technical solution. This application protects the technical solution of the WiFi data transmitting module W1 sending data, the WiFi data receiving module receiving data and displaying the patient's exercise data. Figure 2 Among them, the battery G1 is a 12V / 5Ah lithium battery; the charging socket C1 is a coaxial power socket (the external power charger plug is inserted into the charging socket C1 to charge the battery G1); the resistance value of the resistor R1 is 9K; the resistance value of the annular hollow resistor RP is 120K; the WiFi data transmission module W1 is a finished WiFi data transmission module of model NRF24L01.
