Description

Turnover device for patient with reduced pressure femur fracture Technical Field The invention relates to the technical field of medical appliances, in particular to a turnover device for a patient suffering from reduced pressure femoral fracture. Background The femoral fracture is a common clinical orthopaedics injury, patients need to lie in bed for a long time, and in the period, in order to avoid pressure sores caused by long-term compression of body parts, simultaneously promote blood circulation of limbs, reduce the incidence rate of complications and regularly turn over the patients for nursing. However, the fracture part of the femoral fracture patient has extremely poor bearing capacity, if the fracture part is improperly operated in the turning process, the fracture end is easily shifted, pain is aggravated, even secondary damage is caused, serious influence is brought to the rehabilitation of the patient, and the nursing workload and the operation difficulty of medical staff are greatly increased. At present, most of femoral fracture patients commonly used clinically are manually turned over or turned over by simple auxiliary instruments, the manual turning over requires the cooperative operation of a plurality of medical staff, not only consumes labor, but also has difficult accurate control of turning over force and angle, and cannot effectively ensure the stable body position of the patient, the simple auxiliary instruments have single multi-structure and can only realize single-side turning over, difficult to meet the nursing requirement of left and right bidirectional turning over of the patient, and lack of effective positioning and buffer structures, the patient is easy to slide and have dislocation in the turning over process, the reliable decompression effect cannot be realized, the falling bed risk is caused by the deviation of the patient from the center of the bed body, and meanwhile, the problems of part interference, insufficient stability and the like are easy to occur in the instrument transmission process. Therefore, a turnover device for a patient suffering from the reduced pressure femur fracture is designed. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a turnover device for a patient suffering from reduced pressure femur fracture, which solves the problem that the patient suffering from femur fracture in clinical common turnover mode has manual and simple auxiliary equipment for turnover. The manual turning-over consumes manpower and is difficult to accurately control, the simple auxiliary instrument has a single structure, the bidirectional turning-over requirement is difficult to meet, the patient is easy to slide and misplace, the falling-down risk is caused, and the problems of interference of components, insufficient stability and the like exist in the instrument transmission. In order to achieve the above purpose, the present invention adopts the following technical scheme: The turnover device for the patient suffering from the reduced pressure femoral fracture comprises a bed body, a bed plate fixedly arranged on the inner wall of the bed body, a plurality of turnover grooves formed in the top of the bed plate and penetrating through the bed plate, wherein two groups of identical round rods are rotatably arranged in the bed body, damping structures are arranged at the contact parts of the round rods and the inner wall of the bed body, so that the round rods keep static and do not move when the round rods are not acted by external force; the free ends of the first turning plate and the second turning plate are designed in an arc shape, and the first turning plate and the second turning plate are arranged corresponding to the turning grooves on the bed plate and can penetrate through the turning grooves to extend out of the top of the bed plate. Preferably, the outer wall of the hollow rod is provided with a movable groove matched with the width of the turning plate, each turning plate I respectively penetrates through the corresponding movable groove, the movable groove is in arc-shaped design by taking the axis of the hollow rod as the center of a circle, the arc radian is matched with the turning track of the turning plate I, and the hollow rod sleeved on the outer wall of the round rod cannot interfere the turning action of the turning plate I when the round rod drives the turning plate I to rotate. Preferably, two sliding boxes with the same structure are slidably arranged on the inner wall of the bottom of the bed body, the two sliding boxes are fixedly connected into a whole through a connecting rod to realize synchronous sliding, a hydraulic cylinder is fixedly arranged on the inner wall of the bottom of the bed body and positioned at the middle position of the two sliding boxes, an output shaft of the hydraulic cylinder is fixedly connected with the outer wall of one sliding box, and the two sliding boxes are driven to sl
