Description

Technical Field

[0001] The utility model relates to the technical field of medical facilities, in particular to an expansion structure for a transfer bed. Background Technique

[0002] A transfer bed is a special medical bed used for transferring patients between beds, transferring patients from the operating table to the ward, and transferring patients from the ambulance. The use of the transfer bed solves the difficulty of transferring patients from the operating table to the ward after surgery, and reduces the pain and difficulty brought to patients when transferring patients manually in the traditional way.

[0003] However, when the existing transfer beds are put into use, it is necessary for the staff to carry the patient to the top of the transfer bed and then move the transfer bed to the position where transfer is needed. However, most transfer beds transfer different people every day, and there are certain differences in the height, weight and body shape of each person. When the transfer bed needs to transfer a person with a larger body shape, it is necessary for the staff to move a specific transfer bed to the position of the hospital bed and use transfer beds of different models, which brings inconvenience to the medical staff;

[0004] At the same time, when most transfer beds are moved to the vicinity of the hospital bed, it is necessary to pick up and carry the patient onto the hospital bed. When carrying the patient, the body of the staff is prone to collide with the transfer bed. Although the rollers at the bottom of the transfer bed have a braking function and will not move when carrying the patient, a large collision amplitude will still cause the transfer bed to shift in position, so additional staff are needed to support the transfer bed to prevent it from moving, increasing the workload of the staff. Content of the Utility Model

[0005] The purpose of the utility model is to provide an expansion structure for a transfer bed to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an expansion structure for a transfer bed, including a moving component and a hydraulic rod bolted to the top of the moving component, and further including:

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4As shown in the figure, an extended structure for a transfer bed includes a moving component 1. The moving component 1 enables the transfer bed to move. A hydraulic rod 2 is bolted to the top of the moving component 1. The hydraulic rod 2 can control the lifting of the transfer bed. The output shaft of the hydraulic rod 2 is bolted to a bed board 3. The bed board 3 allows a patient to lie on it. Protective plates 4 are provided on both sides of the bed board 3 to prevent the patient from falling off the top of the bed board 3. A handrail 5 is provided on one side of the bed board 3. The number of handrails 5 is two. With the handrails 5, it is convenient for the staff to move the transfer bed. A fixed shell 6 is bolted to the other side of the bed board 3. A hand turntable 7 is provided on one side of the fixed shell 6. A bidirectional threaded rod 8 is fixed to the side of the hand turntable 7 close to the fixed shell 6. The other side of the bidirectional threaded rod 8 is rotatably connected to the inner cavity of the fixed shell 6. A sleeve 9 is threadedly connected to the surface of the bidirectional threaded rod 8. The surface of the sleeve 9 is slidably connected to the inner cavity of the fixed shell 6. A stretching plate 10 is bolted to the side of the sleeve 9 away from the fixed shell 6. The bottom of the stretching plate 10 is slidably connected to the top of one side of the bed board 3. One side of the stretching plate 10 is hinged to one side of the protective plate 4. The top of the bed board 3 and the top of the stretching plate 10 are on the same horizontal plane. With the cooperation of the hand turntable 7 and the bidirectional threaded rod 8, the sleeve 9 can drive the stretching plates 10 on both sides to move in opposite directions at the same time, so that the transfer bed can transfer patients of different body types, increasing the practicality of the transfer bed. A guiding mechanism 11 is provided on the side of the stretching plate 10 away from the fixed shell 6. Under the action of the guiding mechanism 11, it can effectively prevent the stretching plate 10 from shifting in position during operation, increasing the stability of the stretching plate 10, and thus increasing the stability of the transfer bed. A connecting shell 12 is bolted to the top of the fixed shell 6. A moving mechanism 13 is arranged in the inner cavity of the connecting shell 12. A limiting block 14 is provided on one side of the connecting shell 12, and a limiting shell 15 bolted to the hospital bed. A limiting groove 16 is opened in the inner cavity of the limiting shell 15. The surface of the limiting block 14 is slidably connected to the inner wall of the limiting groove 16. The other side of the limiting shell 15 is bolted to one side of the hospital bed. Under the action of the moving mechanism 13, the limiting block 14 can move into the inner part of the limiting shell 15 through the limiting groove 16 to fix the transfer bed to the hospital bed, so as to reduce the shaking of the transfer bed when the staff transfers the patient to the hospital bed and improve the safety of the patient, thereby increasing the practicality of the transfer bed.

[0025] The guiding mechanism 11 includes a mounting shell 111. One side of the mounting shell 111 is bolted to the side of the bed board 3 away from the fixed shell 6. A guiding rod 112 is bolted inside the mounting shell 111. A slider 113 is slidably connected to the surface of the guiding rod 112. One side of the slider 113 is bolted to one side of the extension plate 10. With the cooperation of the bidirectional threaded rod 8 and the sleeve 9, the extension plate 10 can drive the slider 113 to move on the surface of the guiding rod 112. With the cooperation of the mounting shell 111, it effectively prevents the extension plate 10 from shifting in position during operation, increases the stability of the extension plate 10, and thus increases the stability of the transfer bed.

[0026] The moving mechanism 13 includes a moving rod 131. The surface of the moving rod 131 is slidably connected to one side of the connecting shell 12. The cross-sectional shape of the moving rod 131 is L-shaped. A clamping groove 132 is formed inside the connecting shell 12. The inner cavity of the clamping groove 132 is slidably connected to the surface of the moving rod 131. A compression spring 133 is fixed inside the connecting shell 12. The other side of the compression spring 133 is fixedly connected to the surface of the moving rod 131. With the cooperation of the moving rod 131 and the clamping groove 132, the limiting block 14 can enter the inside of the limiting shell 15 through the limiting groove 16, and can limit the compression spring 133. At the same time, the moving rod 131 can rotate inside the clamping groove 132, so that the limiting block 14 can rotate inside the limiting groove 16, so that the connecting shell 12 and the limiting shell 15 can be connected to each other, enabling the transfer bed to be connected to the hospital bed. It effectively reduces the situation that the transfer bed shifts in position when the staff transfers the patient to the hospital bed, thus increasing the stability of the transfer bed.

[0027] Working principle: First, the staff member moves the transfer bed to the position of the hospital bed through the cooperation of the handrail 5 and the moving component 1. Subsequently, under the action of the hydraulic rod 2, the bed board 3 and the extension board 10 can move up and down, enabling the bed board 3 to be on the same horizontal plane as the hospital bed. When the patient has a larger body size and the extension board 10 needs to be adjusted, the staff member rotates the bidirectional threaded rod 8 by turning the handwheel 7. The bidirectional threaded rod 8 drives the two sides of the extension board 10 to move in opposite directions simultaneously through the sleeve 9, moving the extension board 10 away from the bed board 3. Then, a mattress is laid. Subsequently, the staff member rotates the protective board 4 to the bottom of the bed board 3. The staff member moves the moving rod 131 in the inner cavity of the card slot 132. At the same time, the moving rod 131 drives the limiting block 14 to move into the inner cavity of the limiting shell 15 through the limiting slot 16 and compresses the compression spring 133. When the moving rod 131 moves to the position where the card slot 132 can rotate, the staff member rotates the limiting block 14 in the inner cavity of the limiting slot 16 through the moving rod 131. Under the action of the rebound of the compression spring 133, the connection shell 12 and the limiting shell 15 can be connected to each other, fixing the transfer bed to the hospital bed. Subsequently, the staff member transports the patient to be transferred to the top of the bed board 3.
