Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, and in particular to a nursing chair for cardiovascular patients with limb rehabilitation function. Background Technology

[0002] The main cause of cardiovascular disease is abnormal metabolism of smooth muscle cells in the blood vessel wall. Blood vessel tissue and other tissues in the human body complete the process of metabolism within a certain cycle. However, due to the inability of new cell tissue to form normally, the blood vessel wall itself has "defects", which makes it easy to cause inflammation and poor blood vessel contraction. Therefore, appropriate exercise is an important part of the treatment and rehabilitation of patients with cardiovascular diseases.

[0003] In practical applications, existing nursing chairs for cardiovascular patients lack effective internal control mechanisms, resulting in a constant intensity of exercise on the patient's lower limbs. This only meets the basic needs of lower limb rehabilitation in the early stages of cardiovascular disease patients. As the rehabilitation process progresses, the intensity of exercise cannot be adaptively adjusted or increased, thus significantly reducing the effectiveness of the nursing chair for lower limb rehabilitation in the later stages of cardiovascular disease patients. Utility Model Content

[0005] In a first aspect, this utility model provides a nursing chair for cardiovascular patients with limb rehabilitation functions, specifically comprising: a chair, a base support frame, a top support frame, a screw rod, a connecting seat, a pivot shaft, connecting arms, a foot pedal, damping pins, and bolts; the base support frame is connected to the bottom of the chair, and the top support frame is connected to the top of the base support frame; the screw rod is connected inside the base support frame and is connected to the top support frame; the pivot shaft is connected to the top of the top support frame, and connecting arms are connected to both ends of the pivot shaft, with a foot pedal connected to the end of each connecting arm; two damping pins are connected inside the pivot shaft, and two bolts are connected to the top of the pivot shaft, with the damping pins connected to the bolts.

[0006] Furthermore, the rotating shaft is rotatably connected to the connecting seat, and the connecting seat is provided with a guide hole. The damping pin slides through the guide hole, and the bottom end of the damping pin contacts the rotating shaft. When the patient sits on the chair, his feet step on the two foot pedals, which drives the rotating shaft to rotate, thereby achieving the effect of exercising and rehabilitating the patient's lower limbs.

[0007] Furthermore, the top of the connecting seat is provided with a screw hole B, which is located directly above the guide hole. The bolt is threaded into the screw hole B, and a through hole is provided inside the bolt. The top of the damping pin is slidably connected to the through hole.

[0008] Furthermore, a spring is fitted outside the damping pin, with the bottom end of the spring contacting the damping pin and the top end of the spring contacting the bolt. The damping pin is in close contact with the shaft due to the spring's thrust, increasing the shaft's rotational resistance. By rotating the bolt, the spring compression ratio can be changed, increasing or decreasing the shaft's rotational resistance.

[0009] Furthermore, the top support frame and the bottom support frame are slidably connected, the bottom support frame is provided with an upper shaft at the top, the top support frame is provided with an upper sliding hole, and the upper shaft is slidably connected in the upper sliding hole.

[0010] Furthermore, the bottom of the top support frame is provided with a lower shaft, and the bottom support frame is provided with a sliding hole. The end of the lower shaft is slidably connected to the sliding hole, the upper shaft is slidably engaged with the upper sliding hole, and the lower shaft is slidably engaged with the sliding hole, so as to guide the top support frame to move up and down.

[0011] Furthermore, the screw is rotatably connected to the lower shaft, and the upper shaft has a screw hole A inside. The screw is threaded into the screw hole A. Rotating the screw adjusts the height of the top support frame, thereby changing the height of the connecting seat.

[0012] This utility model provides a nursing chair for cardiovascular patients with limb rehabilitation function, which has the following beneficial effects:

[0013] When in use, the patient sits on the chair and places both feet on the two foot pedals, which drives the rotating shaft to rotate, thus providing a lower limb exercise and rehabilitation effect. The damping pin is in close contact with the rotating shaft due to the spring force, increasing the rotation resistance of the shaft. By rotating the bolt, the spring compression ratio can be changed, increasing or decreasing the rotation resistance of the shaft, making it more suitable for the lower limb exercise and rehabilitation needs of patients at different stages.

[0014] In addition, the upper shaft slides into the upper sliding hole, and the lower shaft slides into the lower sliding hole, guiding the top support frame to move up and down. Depending on the patient's height, the screw can be rotated to adjust the height of the top support frame, changing the height of the connecting seat, thus better meeting the needs of lower limb exercise and rehabilitation for patients of different heights.
