Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a turning device for critically ill patients which is convenient to operate. Background Technique
[0002] If a patient lies in bed for a long time without turning over, it will lead to blood circulation disorders, and then complications such as bedsore, muscle contracture, joint stiffness, etc. Among them, bedsore is the most common complication clinically, and in severe cases, it will cause the patient to lose their life. By turning over the patient regularly, the occurrence of bedsore can be avoided. In medical care, it is recommended to turn over the patient once every 2 hours. However, in real life, for some patients with inconvenient lower limb movement, paralysis or special requirements after surgery, it is difficult to turn them over. Medical staff need to manually turn them over using bed sheets or pure cotton bath towels, etc. This makes the labor intensity relatively large, time-consuming and laborious, especially for some patients with a large body weight, and it cannot provide a certain buffer when turning over the patient, which may cause the patient's wound to crack again due to the impact force; Therefore, we propose a turning device for critically ill patients which is convenient to operate to solve this problem. Content of the Utility Model
[0003] The purpose of the utility model is to provide a turning device for critically ill patients which is convenient to operate, so as to solve the problems raised in the above background technique.

A limiting assembly 5 is arranged inside the vehicle frame 1, and the limiting assembly 5 includes: a dual-axis motor 501, lead screws 502 are fixedly installed at the output shafts at both ends of the dual-axis motor 501, threaded plates 503 are threadedly connected to the outside of the two groups of lead screws 502, fixed rods 504 are fixedly installed at the tops of the two groups of threaded plates 503, and baffles 505 are fixedly installed at the tops of the two groups of fixed rods 504.
[0022] In this embodiment, four buffer assemblies 6 are arranged at the bottom of the bottom plate 3. The buffer assembly 6 includes: a sleeve 601, the sleeve 601 is fixedly installed at the bottom of the bottom plate 3, a circular plate 602 is slidably installed inside the sleeve 601, a spring 605 and a damper 604 are arranged inside the sleeve 601, the spring 605 is sleeved outside the damper 604, and both ends of the spring 605 and the damper 604 are fixedly connected to the corresponding circular plate 602 and one inner wall of the sleeve 601 respectively. A connecting shaft 603 is fixedly installed at the bottom of the circular plate 602, and a universal wheel 8 is fixedly installed at the bottom of the connecting shaft 603, which is convenient for buffering the movement of the patient during the turning process. Two short plates are fixedly installed at the top of the bottom plate 3, the first lead screw 406 is rotatably installed inside the two short plates, and a first motor 7 is fixedly installed on one side of the front short plate. The output shaft of the first motor 7 is fixedly connected to the first lead screw 406, which is convenient for the rotation of the first lead screw 406, convenient for the turning of the bed body 2, and convenient for turning the patient.
[0023] In this embodiment, mounting blocks are fixedly installed on both sides of the threaded block 405. The first limiting rods 407 are slidably installed inside the two groups of mounting blocks. The two ends of the two groups of first limiting rods 407 are fixedly connected to the corresponding short plates respectively, preventing the threaded block 405 from rotating when it moves. A bracket is fixedly installed on the bottom inner wall of the bed body 2. The dual-axis motor 501 is fixedly installed on the top of the bracket. The two groups of second lead screws 502 are rotatably installed on the inner walls on both sides of the bed body 2 respectively. The two groups of second limiting rods are slidably installed inside the two groups of threaded plates 503. The two ends of the two groups of second limiting rods are fixedly connected to the inner walls on both sides of the bed body 2 respectively. Two sliding grooves are formed in the top of the bed body 2. The two groups of fixing rods 504 are slidably installed inside the corresponding sliding grooves, preventing the threaded plates 503 and the fixing rods 504 from rotating when they move. Three wearing grooves are formed inside each of the two groups of baffles 505, facilitating the wearing of the traction belts and effectively protecting patients with different body builds.
[0024] In this embodiment, during use, the drive motor one 7 is activated, causing the motor one 7 to drive the lead screw one 406 to rotate, making the threaded block 405 drive the sliding frame 404 at the top to move. The slider 403 slides inside the sliding frame 404. Since the fixing rod 504 is rotatably installed inside the slider 403, when the slider 403 moves on the sliding frame 404, the fixing rod 504 drives the connecting frame 9 to rotate. Then, since the bed body 2 is hinged to the vehicle frame 1, the bed body 2 can be flipped to turn over the patient. By driving the dual-axis motor 501, the dual-axis motor 501 drives the two groups of second lead screws 502 on both sides to rotate, making the two groups of threaded plates 503 drive the fixing rods 504 and the baffles 505 at the top to move correspondingly, enabling the two groups of baffles 505 to limit the patient according to the patient's body shape. At this time, by passing the traction belt through the wearing grooves formed in the two groups of baffles 505, it is possible to prevent the patient from falling off the bed body 2 when turning over. When turning over the body or moving the vehicle frame 1, vibrations are inevitably generated. At this time, under the action of its own and external forces, the connecting shaft 603 at the top of the universal wheel 8 drives the circular plate 602 at the top to squeeze the spring 605 and the damper 604 inside the sleeve 601, achieving a buffering and shock-absorbing effect.
