technical field

The utility model relates to the technical field of medical instruments, in particular to a nursing chair for joint surgery.

Background technique

Rheumatoid arthritis is one of the common joint diseases, which can affect both men and women. It not only affects people's normal life, but also leads to the loss of mobility, so it has attracted more and more attention. The most important pathological manifestation of rheumatoid arthritis is joint pain, which is also the most painful symptom. Knee joint pain is the majority, and there are general malaise, fatigue, poor appetite, weight loss, and joint deformity in severe cases.

The above-mentioned prior art solution has the following defects: in the conventional nursing mode, the medical staff manually helps the patient perform flexion and extension activities, which greatly increases the work intensity of the medical staff.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a nursing chair for joint surgery. By setting an adjustment device on the seat, the bending of the knee joints of the patient's legs can be realized, thereby greatly reducing the need for medical staff. work intensity.

The above-mentioned purpose of the utility model is achieved through the following technical solutions:

A nursing chair for joint surgery, comprising a chair frame, an adjustment device is provided at the bottom of the chair frame, the adjustment device includes a support plate, the support plate is arranged horizontally, the support plate is fixedly connected with the chair frame, and the Both sides of the end surface of the support plate are provided with wedge-shaped grooves, and a wedge-shaped plate is slidably connected to the wedge-shaped groove, and a rack is fixedly connected to the top of the wedge-shaped plate, and a gear is arranged between the two racks. The two sides are respectively meshed with the two racks, the gears are rotatably connected to the support plate, and the front sides of the two racks are fixedly connected with horizontally arranged support rods, and the front ends of the support rods are fixedly connected There is a pin, and the pin is slidingly connected with a guide rail, and the guide rail is fixedly connected with a rotating plate, and the rotating plate is hinged with the chair frame, and one side of the rack close to the support bar is fixedly connected with a horizontal A slide rail is provided, and a slider is slidably connected in the slide rail, and a connecting rod is hinged at the top of the slider, and the end of the connecting rod away from the slider is fixedly connected with a vertically arranged connecting shaft. A motor is fixedly connected to the top of the shaft, the axis of the output end of the motor coincides with the axis of the connecting shaft, and the motor is fixedly connected to the chair frame.

By adopting the above-mentioned technical scheme, by setting the adjustment device on the chair frame, the bending movement of the knee joints of the patient's legs can be realized, thereby greatly reducing the work intensity of the medical staff. By setting the support plate, the support effect can be achieved. The wedge-shaped groove can limit the position of the wedge-shaped plate, and the wedge-shaped plate can also slide horizontally in the wedge-shaped groove. By setting the rack and gear, the rack on one side can be driven by the gear as the wedge-shaped plate slides. The rack on the other side of the driving gear and the wedge-shaped plate slide horizontally in the opposite direction, and the set rotating plate can place the patient's legs. When the gear rotates clockwise, the gear drives the rack on the right side and the wedge plate to move horizontally forward along the wedge groove. At this time, it can drive the support rod on the right side to move synchronously, thereby exerting a force against the rotating plate horizontally. , so that the rotating plate rotates on the chair frame, thereby achieving the effect of raising the left leg, while the left rotating plate is opposite, and can be driven to rotate downward by the backward sliding of the left rack and wedge-shaped plate. Thereby the effect of lowering the right leg is realized. By setting the slide rail and the slide block, the slide block can be made to slide horizontally along the slide rail.

The slide rail is limited by the rack and drives the rack and the wedge plate to slide. At this time, the gear acts on the rack on the other side. To achieve the transmission effect, along with the continuous rotation of the motor, the two racks are driven by the slide rails to reciprocate, so that the right side rotating plate for placing the left foot and the left rotating plate for placing the right foot continue to reciprocate.

In a preferred example, the utility model can be further configured as follows: both sides of the top of the chair frame are fixedly connected with handrails, and the rear end of the chair frame is rotatably connected with a back board.

By adopting the above-mentioned technical scheme, by setting the rotation connection between the backboard and the chair frame, the angle of the backboard can be adjusted conveniently, thereby facilitating the patient to adjust the comfort level, and the provided armrests can facilitate the placement of the patient's hands.

In a preferred example, the utility model can be further configured as: one of the handrails is fixedly connected with a controller.

By adopting the above technical solution and setting the controller, the patient can conveniently control and adjust the speed of the motor speed according to the bearing force of his legs.

In a preferred example, the utility model can be further configured as: a massage cushion is provided on the front side of the backrest board.

By adopting the above technical proposal, by setting the massage cushion, the patient can be massaged, thereby relieving the patient's tension.

In a preferred example, the utility model can be further configured as: the rotating plate is fixedly connected with a pedal.

By adopting the above-mentioned technical scheme, by setting the foot pedal, it is convenient for the patient to place the foot.

In summary, the utility model includes at least one of the following beneficial technical effects:

By setting the adjustment device on the chair frame, the bending of the knee joints of the patient's legs can be realized, thereby greatly reducing the work intensity of the medical staff. By setting the support plate, it can play a supporting effect, and the wedge-shaped groove can be adjusted. While the plate is limited, the wedge-shaped plate can also slide horizontally in the wedge-shaped groove. By setting the rack and gear, the rack on one side can drive the other side of the gear through the transmission of the gear as the wedge-shaped plate slides. The gear rack and the wedge-shaped plate slide horizontally in the opposite direction, and the set rotating plate can place the patient's legs. Through the set support rod, latch, and guide rail, it can play the role of connecting the rotating plate. When the gear rotates clockwise , the gear drives the rack on the right side and the wedge plate to move horizontally forward along the wedge groove. At this time, it can drive the support rod on the right side to move synchronously, thereby exerting a force against the rotating plate horizontally, so that the rotating plate is in the seat. Rotate on the frame, so as to achieve the effect of raising the left leg, while the rotating plate on the left is opposite, and can be driven by the left rack and wedge plate to slide backward, so as to realize the lowering of the right leg By setting the slide rail and the slider, the slider can slide horizontally along the slide rail, the slide rail can guide and limit the slider, and the connecting rod can connect the slider and the connecting shaft. The motor provided has the effect of providing driving force. Through the clockwise rotation of the motor, the connecting shaft, connecting rod and slider can be driven to rotate synchronously around the axis of the motor output end. The hinged connection between the slider and the connecting rod makes The slider slides along the slide rail and drives the slide rail to move. The slide rail is limited by the rack and drives the rack and the wedge plate to slide. The gear plays a transmission effect on the rack on the other side. As the motor continues to rotate, the two racks are driven by the slide rails to reciprocate, so that the right side rotating plate for placing the left foot and the left rotating plate for placing the right foot continue to reciprocate.
