Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to an auxiliary inspection device for rheumatoid arthritis. Background Art

[0002] Rheumatoid arthritis is a chronic, systemic disease with inflammatory synovitis as the main feature, characterized by polyarticular, symmetrical, invasive joint inflammation of the small joints of the hands and feet, often accompanied by involvement of extra-articular organs and positive serum rheumatoid factor, which can lead to joint deformity and loss of function. Since the examination of rheumatoid arthritis usually adopts imaging examination methods such as X-ray, CT, MRI and ultrasound, the most common parts of rheumatoid arthritis are wrists, palms, and fingers, followed by toes, knees, ankles, elbows and shoulders. When performing X-ray examination of the knee joint, if the patient is lying down, the joint is loose and cannot reflect the actual situation. In order to ensure the accuracy of the examination results, it is necessary to take a weight-bearing X-ray of the knee joint, that is, to take the picture when the knee is straight and standing with weight. Since the patient's diseased joint is accompanied by pain, during the imaging examination, the patient will cause joint movement due to pain, which affects the clarity and accuracy of the imaging examination results. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide an auxiliary examination device for rheumatoid arthritis to solve the problems raised in the above background technology.

[0005] The beneficial effect of the utility model is that by providing a support frame and a leg positioning component, the patient's thigh and calf can be clamped and fixed, so as to position the affected leg for X-ray shooting, so as to prevent the patient from shaking or moving due to joint pain when standing for shooting, thereby affecting the shooting effect.

[0006] To increase the comfort of the patient's legs and the security of the leg positioning:

[0007] As a further improvement of the above technical solution: the positioning clamp ring and the airbag ring are both arranged in a semicircular arc shape.

[0008] The beneficial effect of this improvement is that the semicircular arc-shaped positioning clamp and the airbag ring are adapted to the contour of the human body's limbs, which can increase the comfort of the patient's legs and the firmness of the leg positioning.

[0009] To accommodate patients of different heights:

[0010] As a further improvement of the above technical solution: a slide groove is opened inside the support rod, and the inside of the slide groove is slidably connected to a movable block connected by two connecting rods, and the inner top wall and the inner bottom wall of the slide groove are both provided with an electric telescopic rod connected to the movable block.

[0011] The beneficial effect of this improvement is that the height of the movable block can be adjusted by the electric telescopic rod, so that the height of the positioning clamp ring and the air bag ring can be increased to adapt to patients of different heights.

[0012] To facilitate clamping and positioning of the legs:

[0013] As a further improvement of the above technical solution: a standing plate is arranged at the bottom of the supporting rod, and the positioning clamp ring is located directly above the standing plate.

[0014] The beneficial effect of this improvement is that when the patient stands in the middle of the standing board, the legs are just stuck in the positioning clamp ring, which can facilitate the clamping and positioning of the legs, so as to prevent the patient's legs from bending due to pain when taking X-rays and affecting the shooting effect.

[0015] To prevent the support legs and support poles from affecting the shooting effect:

[0016] As a further improvement of the above technical solution: support legs for increasing the stability of the support frame are symmetrically arranged at both ends of the support frame, and the standing board is located between the support legs and the support rods. When the patient stands on the standing board, it does not overlap with the support legs and the support rods.

[0017] The beneficial effect of this improvement is that when the patient stands on the standing board, the supporting legs and the supporting rods will not block the legs and will not affect the shooting effect.

[0018] To facilitate the support of patients of different heights:

[0019] As a further improvement of the above technical solution: the support frame is arranged in a semicircular arc shape, and the top of the support frame is connected to a plurality of auxiliary frames with the same spacing through support columns.

[0020] The beneficial effect of this improvement is that by providing multiple auxiliary frames, it is possible to facilitate the support of patients of different heights.

[0021] To improve the efficiency of knee joint examination:

[0022] As a further improvement of the above technical solution: the micro air pump is an integrated inflation and deflation pump.

[0023] The beneficial effect of this improvement is that when the thigh and calf are fixed, the airbag ring is inflated using a micro air pump, and after the examination is completed, the airbag ring is deflated using the micro air pump, which is easy to operate and can improve the efficiency of knee joint examination.
