Description

Technical Field

[0001] The present invention relates to the technical field of medical beds, in particular to a prone turning bed for critically ill patients. Background Art

[0002] Prone ventilation involves placing the patient in a prone position, using gravity to recruit the lungs to improve the ventilation-perfusion ratio and lung compliance. As a specialized ventilation method, it's often used clinically for critically ill patients, such as those with ARDS and severe pneumonia.

[0003] Patent number CN117084876A discloses a prone-position turning bed, comprising a bed frame, a main bed board, a secondary bed board, a lifting platform, a turning drive mechanism, and restraining fixtures. The main bed board is mounted on the bed frame; the secondary bed board is arranged side by side and adjacent to the main bed board in the width direction of the bed frame; the lifting platform is mounted on the bed frame and located below the main bed board; the turning drive mechanism is mounted on the bed frame and located below the secondary bed board, and is used to drive the secondary bed board to turn 180 degrees around a horizontal axis and switch between a first position and a second position; the restraining fixtures are mounted on the secondary bed board and are used to restrain and secure the patient to the secondary bed board; when the secondary bed board is in the first position, the secondary bed board is in the same plane as the main bed board; when the secondary bed board is in the second position, the secondary bed board is located above and parallel to the main bed board. This prone-position turning bed adopts electromechanical power as the turning power instead of manual turning, reducing the uncertainty caused by manual turning, improving the patient's turning experience, and reducing labor costs and burdens.

[0004] The above-mentioned device uses electromechanical power to replace the original manual flipping, reducing the uncertainty factors brought by manpower. However, when turning over, the patient's entire body needs support. Relying only on two restraint belts to fix the patient, the patient is not only prone to sliding, but also the small area of ​​fixation often causes the patient to be strangled at the fixation point, causing discomfort to the patient. In addition, the body size of patients varies greatly. When turning over from the initial bed surface to the target bed surface, the distance between the patient and the target bed surface is too large. When the patient is released, the patient will be thrown onto the target bed surface, which can easily worsen the condition of critically ill patients and even put the patient's life in danger. For fatter patients, it is easy to cause oppression on the patient and cause discomfort to the patient. Summary of the Invention

The output shaft of the second motor 45 rotates to drive the linkage gear 46 to rotate and at the same time drive the third bed board 3 to flip ninety degrees. Then the output shaft of the first motor 14 rotates to drive the first flip shaft 8 to rotate. The rotation of the first flip shaft 8 drives the third One bed board 1 rotates, and the first bed board 1 turns the patient sideways and presses the patient on the second bed board 2. The patient's sideways body presses the corresponding number of wedge plates 62, so that the wedge plates 62 move downward, and the wedge plates 62 move downward to drive the first wedge blocks 63 to move toward the two ends of the second bed board 2. The movement of the first wedge blocks 63 drives the synchronous movement of the interference columns 64, and the movement of the interference columns 64 drives the corresponding segmented racks 52 to move. The movement of the segmented racks 52 drives the corresponding spring columns 53 and the L-shaped wedge blocks 54 to move synchronously, and then the output shaft of the second motor 45 rotates to drive the linkage gear 46 rotates, and the linkage gear 46 meshes with the segmented rack 52, so that the third bed board 3 moves toward the second bed board 2, until the third bed board 3 moves to the position where the segmented rack 52 is abutted, and the second wedge block 57 abuts with the corresponding L-shaped wedge block 54, so that the locking shaft 510 moves toward the second bed board 2, and the movement of the locking shaft 510 drives the cross block 59 to move synchronously, and the cross block 59 is engaged with the corresponding cross shaft, so that the third bed board 3 stops moving. At this time, the locking mechanism 5 is abutted by the abutting mechanism 6, so that the locking mechanism 5 is locked with the second bed board 2. At this time, the output shaft of the linkage motor 41 rotates to drive the third bed board 3 and the second bed board 2 to flip ninety degrees in the opposite direction. Then, the output shaft of the cylinder 71 extends to drive the U-shaped plate 73 to move. After the U-shaped plate 73 moves to engage with the reset groove 72, the output shaft of the second motor 45 rotates in the opposite direction, thereby driving the second bed board 2 to move up until the linkage gear 46 is disengaged from the segmented rack 52.
