Description

Technical Field

[0001] The invention belongs to the technical field of knee brace equipment, and in particular to a pressure monitoring device for a knee joint load-reducing walker. Background Art

[0002] The existing wearable knee joint load-reducing walker is a bionic device based on a cam structure that simulates the functional structure and movement of the human knee joint. The upper section of the pointed follower rod in the cam mechanism is combined and fixed with the tower-shaped cylindrical skin traction device as an integral structure, so that the skin traction device moves along the movement trajectory of the follower rod. After the walker is worn on the human knee joint, the tower-shaped cylindrical skin traction device together with the upper section of the pointed follower rod are tied to the middle and lower sections of the human thigh through a strap. When walking, as the knee joint extends and flexes back and forth, the pointed follower rod follows the changes in the position of the middle and lower sections of the thigh; the pointed structure of the follower rod simulates the gait trajectory of the femoral condyle of the human knee joint, and is converted into a specific movement path through the cam mechanism, resulting in continuous forward sliding and vertical upward displacement changes. When the knee joint is in flexion, the top of the lower end of the follower rod slides forward from the center of the cam mechanism, and the upper part of the follower rod links the tower-shaped cylindrical skin traction device to move forward toward the knee joint; when the knee joint is in extension, the top of the lower end of the follower rod slides back to the center of the cam mechanism, and the cam structure forces the follower rod to move vertically upward, and the tower-shaped cylindrical skin traction device rises accordingly, generating an upward skin traction force on the middle and lower thigh, so that the middle and lower femur and femoral condyle are indirectly pulled, forming a resistance to the gravity of the thigh acting on the knee joint, and instantly increasing the distance between the tibiofemoral joint surfaces of the knee joint. When the knee joint is flexed and displaced again, the tower-shaped cylindrical skin traction device moves back and forth with the top of the follower rod and enters the next skin traction cycle. According to Newton's third law, the force between the middle and lower thigh of the human body and the top of the follower rod skin traction device is the interaction force between the two objects, that is, the action and reaction forces of equal magnitude and opposite directions occurring on the same straight line. The traction force given to the thigh by the pointed driven rod tower-shaped cylindrical skin traction device is the gravity received by the device, which is equal in magnitude but acts on different objects. The gravity received by the device is transmitted to the ground through the walker support structure, buffering the compressive stress of the femoral condyle on the tibiofemoral joint and reducing the load on the knee joint.

[0003] During the design and manufacturing process of the knee load-reducing walker, pressure sensors were used to conduct phased inspection and testing. The measured parameters verified the effectiveness of the product, and it has achieved good therapeutic effects in clinical use.

[0004] However, since there is no monitoring equipment installed in the knee load-reducing walker, patients can only rely on their own feeling to judge whether the product is used correctly when wearing it. They cannot understand the causal relationship between the skin traction force of the walker, the tension of the strap and the variable load replacement force of the device, and therefore cannot judge whether the walker is in the best therapeutic state.

[0005] Without monitoring equipment, which means it cannot be connected to the Internet, doctors cannot understand whether the patients are using the equipment correctly and find it difficult to provide guidance.

[0006] In addition, for designers and manufacturers, it is impossible to collect big data on patient treatment conditions, making it difficult to make accurate judgments on product upgrades.

[0007] Injury to the meniscus of the human knee joint can easily lead to damage to the cartilage surface of the knee joint, especially damage to the cartilage surface of the tibial plateau, which can eventually lead to joint damage. However, trauma and rupture of the meniscus and cartilage surface, no matter how to treat it, need to be repaired in a specific and continuous mechanical environment. Although the existing knee joint load-reducing walker can provide a mechanical rehabilitation treatment environment for the above injuries, it cannot fully meet the treatment viewpoints of modern medical science.

[0034] like Figures 1 to 3As shown, the support frame 3 is connected to the second return mechanism, and the second return mechanism includes a second support column 8 connected to the support frame 3 and a second spring 9 sleeved on the second support column 8 and sandwiched between the support frame 3 and the calf support plate 2. The calf support plate 2 has a second accommodating groove for accommodating the second spring 9, and the support frame 3 is located between the second accommodating groove and the thigh support plate 1. The second spring 9 provides an upward elastic support force to the support frame 3, and the second spring 9 is sandwiched between the support frame 3 and the inner bottom wall of the calf support plate 2.

The top surface of the support frame 3 is in contact with the bottom surface of the thigh support plate 1, the top surface of the support frame 3 is a circular arc surface, and the bottom surface of the thigh support plate 1 is also a circular arc surface. The axis of the top surface of the support frame 3 and the axis of the bottom surface of the thigh support plate 1 are parallel to the axis of the pin 11. The second spring 9 is a cylindrical coil spring, whose axis is parallel to the length direction of the calf support plate 2. A plurality of second springs 9 are arranged side by side along the width direction of the calf support plate 2. The upper ends of all second springs 9 abut against the support frame 3, thereby improving the stability of the support frame 3 and providing sufficient elastic supporting force. The second support column 8 is vertically arranged, and the length direction of the second support column 8 is parallel to the length direction of the second receiving groove. The support frame 3 is located above the second support column 8, and the upper ends of the two second support columns 8 are respectively fixedly connected to the two ends of the support frame 3 in the arc length direction. A plurality of second receiving grooves are arranged, and a second spring 9 is respectively arranged in each second receiving groove. The return mechanism is arranged between the thigh support plate 1 and the calf support plate 2, and can transmit the gravity from the femur to the calf, thereby avoiding concentrated loads and reducing the compressive stress of the tibiofemoral joint.

[0035] In this embodiment, if Figures 1 to 3 As shown, two second springs 9 are provided, and a certain distance is provided between the two second springs 9, and each second spring 9 respectively abuts against one end of the support frame 3. The mounting plate 4 and the first return mechanism are located between the two second springs 9, two first springs 7 are provided, and two first support columns 6 are provided, and the length direction of the first support column 6 is parallel to the length direction of the second support column 8.

[0036] like Figures 1 to 3As shown, the first pressure sensor 5 is a thin film sensor, which is a thin sheet structure. The first pressure sensor 5 is electrically connected to the first processor, and the first pressure sensor 5 converts and outputs a standard signal corresponding to the pressure to the first processor. The first processor and the first display 12 are fixedly arranged on the calf support plate 2, and the first processor is electrically connected to the first display 12. The first pressure sensor 5 transmits the detected pressure data to the first processor, and the first processor controls the first display 12 to display the pressure data in real time. In the state without pressure, the first spring 7 and the second spring 9 are in a free state, the pressure value detected by the first pressure sensor 5 is zero, and the pressure value displayed on the first display 12 is zero. When the support frame 3 is subjected to the downward pressure applied by the thigh support plate 1, the first pressure sensor 5 contacts the support frame 3, the first spring 7 and the second spring 9 are compressed, and a part of the pressure is transmitted to the calf support plate 2, the first pressure sensor 5 can detect the pressure value, and transmit the received pressure data to the first processor, and the first display 12 displays the pressure change curve, which is used to reflect the change process of the pressure detected by the first pressure sensor 5, the abscissa of the pressure change curve is time, and the ordinate of the pressure change curve is the pressure value detected by the first pressure sensor 5.

[0037] like Figures 1 to 3 As shown, the lower end of the thigh support plate 1 is a fusiform tip, which is a functional structure imitating the femoral condyle and is perpendicular to the thigh support plate 1. When the human knee joint is in the straight position, the tip vertically squeezes the support frame 3, causing it to squeeze the first pressure sensor 5, and transmits the thigh gravity received by the thigh support plate 1. At the same time, the thigh support plate 1 is raised by the squeezing effect of the space reduction of the support frame 3 and the rectangular raised platform groove, and the skin traction device at the upper end generates skin traction force on the thigh. At this time, the monitoring device displays the maximum compressive stress peak value of the walker device load with a change curve. When the knee joint turns to flexion, the tip of the thigh support plate 1 breaks away from the support frame 3 and slides forward, and the monitoring device displays the load compressive stress value as a curve. When the fusiform structure at the lower end of the thigh support plate 1 is parallel and located above the support frame 3, the first pressure sensor 5 is unloaded and rises accordingly, and the compressive stress peak change curve tends to zero. When the knee joint enters the next round-trip cycle of the straight position to flexion again, the monitoring device displays that the compressive stress value enters the next curve change cycle.

The neoprene layer is provided with air holes, and a plurality of air holes are provided and all the air holes are evenly distributed on the neoprene layer. After punching, the airtight characteristic can be changed.

The cloth layer is made of flannel fabric, and the cloth layer is the surface structure of the skin traction adhesive patch. The cloth layer is pasted with the neoprene layer through a composite process, and together with the neoprene layer and the anti-skid point lining 24, it forms the skin traction adhesive patch.
