Description

Technical Field

[0001] The utility model belongs to the technical field of medical rehabilitation equipment, and particularly relates to a postoperative rehabilitation training device. Background Art

[0002] In life, when people are walking or exercising, they may sprain their feet, usually causing ligament injuries. Foot injuries will affect people's mobility and indirectly bring troubles to people's lives and work. Therefore, during the process of taking medicine for treatment, auxiliary rehabilitation training is also needed to enable the feet to recover quickly and relieve the pain of patients. For existing postoperative rehabilitation training devices, after people's hips are injured, due to the influence of their own postoperative conditions, they need to stay in bed for a long time. Long-term bed rest increases the risks of pressure sores, infections, etc. For the patients themselves, simply staying in bed may cause deformation of the foot bones and inability to maintain the foot in a reduced position. There is a great possibility that the patients will have foot deformities, muscle group atrophy and rigidity, and functional disabilities of the affected limb. Postoperative rehabilitation training is required to prevent the problem of disability of the feet caused by long-term immobility after surgery. Content of the Utility Model

[0003] The purpose of the utility model is to provide a postoperative rehabilitation training device. By setting an expansion mechanism, rehabilitation training for the feet can be carried out, which can help restore the foot function and relieve pain, and improve the practicability of the device. It solves the problems that existing long-term bed rest leads to deformation of the foot bones, inability to maintain the foot in a reduced position, and a great possibility that the patients will have foot deformities, muscle group atrophy and rigidity, and functional disabilities of the affected limb.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model is a postoperative rehabilitation training device, including a seat. The four-week bottom of the seat is fixedly connected with legs. On the mutually close sides of the leg at the front end and the leg at the rear end, cross bars are fixedly connected. On the mutually close sides of the two cross bars, a connecting plate is fixedly connected. It also includes an expansion mechanism. The expansion mechanism includes a motor fixedly connected to the left end of the top of the connecting plate. The output end of the motor is fixedly connected with a rotating rod. The bottom of the rotating rod is fixedly connected with a rotating plate. The bottom edge of the rotating plate is rotationally connected with a connecting rod. The top of the end of the connecting rod away from the rotating plate is rotationally connected with a toothed rod.

[0006] Furthermore, a pedal is fixedly connected to the left side of the leg on the left side. A first sliding groove is opened at the middle axis of the inner wall bottom of the pedal. The first sliding groove is slidably connected with the bottom of the toothed rod. Half toothed rods are meshed with the front and back of the toothed rod.

[0007] Further, a rotating rod is rotatably connected to the centers of the two half-toothed rods. Hollow rods are slidably connected to the ends of the two half-toothed rods away from the toothed rod. Springs are fixedly connected to the ends of the two half-toothed rods away from the toothed rod.

[0008] Further, the end of the spring away from the half-toothed rod is fixedly connected to the left side inner wall of the hollow rod. Pulleys are rotatably connected to the bottoms of the left ends of the two hollow rods. Second chutes are provided at the front and rear of the inner bottom of the pedal.

[0009] Further, the two pulleys are slidably connected to the inner walls of the second chutes. Arc-shaped openings are provided at the front and rear of the top of the pedal.

[0010] Further, a fixing mechanism is provided on the top of the pedal. The fixing mechanism includes support blocks fixedly connected to the tops of the two hollow rods. Concave bins are fixedly connected to the tops of the two support blocks. Air bags are fixedly connected to the front and rear of the inner walls of the concave bins.

[0011] Further, air pipes are fixedly connected and communicated to the left and right sides of the bottoms of the two air bags.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, by setting an expansion mechanism, when the motor is started, the rotating rod is driven to rotate. The rotation of the rotating rod drives the rotating plate to rotate. The purpose of setting the rotating plate is that when the rotating plate rotates, the connecting rod can be pulled, so that the toothed rod moves reciprocally, and the device moves back and forth in a cycle. The rotation of the rotating plate drives the bottom connecting rod to perform eccentric rotation. The rotation of the connecting rod pulls the toothed rod to move reciprocally. The purpose of setting the hollow rod is that the bending degree of the second chute can be adjusted, so that the half-toothed rod contracts inside. When the half-toothed rod contracts, it squeezes the spring, driving the foot placed inside the fixing mechanism to perform a half-cycle movement, so as to perform rehabilitation training on the foot, which can help restore the foot function and relieve pain, and improve the practicability of the device.

[0015] 2. In this utility model, by setting a fixing mechanism, after placing the foot inside the fixing mechanism, the sole of the foot first contacts the pedal. The gravity of the foot squeezes the pedal. The purpose of setting the pedal is that for patients whose feet cannot move, the fixing mechanism can also be activated by gravity without the help of others, improving the applicability of the device. When the pressing block is pressed down, the piston plate squeezes the air inside the air chamber into the ventilation pipe. The purpose of setting multiple ventilation pipes is to enable air to quickly enter the airbag. After the air is delivered into the airbag, the airbag expands rapidly. When the airbag expands, it squeezes the foot. The purpose of setting the airbag is to adapt to different foot shapes for fixation, and the soft airbag can prevent secondary damage to the foot, improving the practicality of the device.

[0016] Of course, it is not necessary for any product implementing this utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
