Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic nursing, in particular to a turning device for an orthopedic bed. Background Art

[0002] After orthopedic surgery, patients need to stay in bed for observation and recuperation, but they have difficulty moving and need some devices to assist them in turning over.

[0003] A Chinese patent discloses a patient turning over auxiliary device for orthopedic nursing, with the announcement number CN213641714U, comprising a bottom plate, electric telescopic rods are installed at the top of the bottom plate and near the four corners, two electric telescopic rods near the front and two electric telescopic rods near the back form a group, the tops of the two groups of electric telescopic rods are fixedly connected with a mounting frame, the bottom of the inner wall of the fixed frame is fixedly connected with a return spring at equal distances along the horizontal lateral direction, the top of the return spring is fixedly connected with a baffle, and the center of the left and right sides of the baffle are fixedly connected with a slider; the utility model uses a fixed frame, a return spring and a baffle, in conjunction with a slide groove and a slider, so that the baffle can be retracted when it is not needed, which will not affect the work of medical staff, and when the medical staff does not need to examine the patient, the baffle can be raised to block the patient to prevent the patient from falling from the auxiliary device.

[0004] However, there are still the following disadvantages: the device deflects the installation frame by telescoping the electric hydraulic rod in the air to assist the patient to turn over, but when people turn over, they turn over with the lower part of the arm as the axis, not the lower part of the spine. When the device is in use, the placement board constantly squeezes the patient's body, forming a triangular cavity area under the patient's spine, which seriously affects the user experience. To this end, we proposed a turning device for orthopedic beds to solve this problem. Utility Model Content
