Description

Technical Field

[0001] The invention relates to the technical field of personnel transfer, in particular to a patient transfer bed. Background Art

[0002] In the medical field, in order to perform surgery on patients with spinal injuries and other bedridden patients due to illness, the patients need to be moved to the operating room. However, due to spinal injuries and bedridden patients due to illness, they cannot walk independently, so multiple medical staff and family members are required to cooperate to transfer the patient weighing hundreds of pounds from the hospital bed to the transfer bed, and then multiple medical staff will transfer the patient from the transfer bed to the operating table. The above-mentioned patient transfer process requires medical staff to have great strength, but currently most medical staff are women, and it is difficult for them to complete the transfer of patients weighing hundreds of pounds or even one or two hundred pounds. Therefore, it is necessary to second personnel from other positions to assist. This method affects the work of other positions. In addition, during the transfer process, medical staff are distributed on both sides of the bed, and the obstruction of the bed affects the transfer of patients.

[0003] In order to facilitate the transfer of patients, the existing patent CN108113827A discloses a medical postoperative patient transfer device, in which wheels are installed at the bottom of the base, a moving device is installed at the top of the base 1, an L-shaped bracket is connected to the moving device, a conveying device is installed on the inner right side of the top of the L-shaped bracket, an operating table is provided on the right side of the base, and a supporting component is provided on the operating table. The principle is to push the entire device to the left side of the operating table. The wheels can facilitate better movement of the entire device and place the conveying device directly above the bed. The conveying device is connected to the supporting component on which the patient is lying at this time and started. After the patient is lifted off the operating table to a certain position, the conveying device is turned off, the moving device is started to drive the L-shaped bracket to move to the right, the L-shaped bracket moves to the right to transfer the patient to the top of the bed, and then the moving device is turned off. The conveying device is restarted to place the patient on the bed, and then the conveying device is turned off and separated from the supporting component.

[0004] Although the above-mentioned transfer device can realize the transfer of patients, the above-mentioned supporting component adopts a supporting mesh, which is easy to bend and gather under external force, thereby causing the patient's body to bend. This has little impact on general patients, but has a greater impact on people with spinal injuries, because patients with spinal injuries need to lie flat to recuperate. If their bodies are twisted, it will be detrimental to the patient's recovery and may even affect the patient's treatment effect.

[0005] And when transferring patients for treatment, medical staff need to push the transfer bed and the transfer device into the patient rest area at the same time. The original patient rest area has limited space, and placing the transfer bed and the transfer device at the same time will not be conducive to the transfer work. At the same time, because the transfer device is inconvenient to store, its storage is also a problem. Because its size is large, it occupies a large space. If the transfer device and the transfer bed are combined into one, it will be conducive to the transfer of patients. In addition, the problem of storage of the transfer device can be eliminated.

The inner plate and the supporting plate 43 are hingedly arranged, so that the vertical plate 32 can be controlled to rotate under the action of external force, and then the position of the supporting assembly 2 can be adjusted to move it from the patient's rest bed to the bed body 1, which changes the current situation in Example 1 that the state of the transfer device needs to be adjusted, and improves the flexibility of the device. Because the vertical plate 32 is set as an up and down through structure, and the size of the lifting plate 34 is smaller than the size of the inner space of the vertical plate 32, the lifting plate 34 and the vertical plate 32 can be disassembled, and the lifting plate 34 can be placed in the vertical plate 32 to avoid the vertical plate 32 and the lifting plate 34 not being placed in parallel to affect the folding and storage of the transfer device.

[0049] like Fig.14As shown, in order to make the vertical plate 32 stable in a vertical or horizontal state, a square groove 434 is provided on the connecting column 431, one end of the square groove 434 extends to the end surface of the connecting column 431, and a through hole 433 is provided at one end of the square groove 434 adjacent to the supporting plate 43, and a connecting rod is provided through the through hole 433, the end of the connecting rod protrudes from the connecting column 431, and a pulling plate 435 is hingedly provided. A square column 436 is movably provided at the square groove 434, the length of which is less than that of the square groove 434, and the end of the square column 436 can protrude from the connecting column 431 and be inserted into a square groove (not shown in the figure) of the end wall of the circular groove 423, the cross section of the square groove is the same as that of the square groove 434, and a connecting rod is provided through the other end of the square column 436, and the pulling plate 435 can control the movement of the square column 436. Before the direction of the vertical plate 32 needs to be adjusted, the staff controls the pulling plate 435 to move, forcing the square column 436 to move in the square groove 434, so that its end is out of the square groove, thereby releasing the restriction of the connecting column 431. The medical staff can control the vertical plate 32 to drive the square column 436 to rotate, and adjust the vertical plate 32 to move to the vertical direction or the horizontal direction. After adjusting the direction of the vertical plate 32, the medical staff controls the pulling plate 435 to move, so that the end of the square column 436 is inserted into the square groove, thereby controlling the vertical plate 32 to be stably placed. In order to place the square column 436 more stably, an anti-slip layer can be set on the contact surface between the square column 436 and the square groove 434.

[0050] like Figure 7 , Figure 8 , Fig. 9 , Fig.11 , Fig.12As shown, if the environment is inconvenient to control the vertical plate 32 to rotate relative to the supporting plate 43 to adjust the position of the supporting assembly 2, it is difficult to transfer the patient using the above embodiment. In order to reduce the possibility of the device being restricted by the environment, the mounting seat 4 may also include a limiting tube 41, the upper side of the limiting tube 41 is provided with a second notch, the width of the second notch is smaller than the width of the upper side of the limiting tube 41, a threaded hole 414 is provided at the end of the limiting tube 41, a threaded column 415 is threadedly inserted at the threaded hole 414, a screw rod 413 is fixedly provided at the end angle below the limiting tube 41, a matching plate 411 is provided through the bottom of the screw rod 413, arc grooves are provided on the adjacent side walls of the matching plate 411 and the limiting tube 41, and balls 412 are provided at the arc grooves. In addition, a wheel body 422 is provided on the movable column 42, and the wheel body 422 is located in the limiting tube 41 and is arranged in close contact with the side wall of the limiting tube 41. In addition, the threaded column 415 can resist the wheel body 422 to prevent the wheel body 422 from detaching from the limiting tube 41. At the same time, a mounting slide 11 is provided on the bed body 1, and the mounting slide 11 is arranged along the width direction of the bed body 1, and the end is arranged to be open. Two parallel slide holes 12 are arranged on the bottom surface of the mounting slide 11, and the length of the slide hole 12 is less than the length of the mounting slide 11. The limiting tube 41 is located in the mounting slide 11, and the matching plate 411 is located below the mounting slide 11. The screw 413 is arranged through the slide hole 12, and the ball 412 is in rolling contact with the mounting slide 11. Under the rolling of the ball 412, the resistance of the matching plate 411 and the limiting tube 41 to move relative to the mounting slide 11 is reduced, so that the vertical plate 32 can be controlled to move relative to the bed body 1 under the action of medical staff, and there is no need to rotate the vertical plate 32 to adjust the supporting component 2. When the vertical board 32 moves from one edge of the bed body 1 to the other edge, the supporting assembly 2 is located above the operating table or the resting bed, which provides convenience for transferring patients. Under the cooperation of the matching plate 411 and the screw rod 413, the limiting tube 41 is stably and movably arranged at the installation slide groove 11.
