Technical Field

[0001] This utility model relates to the field of patient transport technology, specifically a patient transport device. Background Technology

[0002] In the healthcare system, patient transport is a crucial process that connects different medical stages and ensures that patients receive timely and appropriate treatment. Whether it is transferring patients from the emergency room to the ward or between different treatment departments, patient transport devices play an indispensable role, directly affecting patient safety and medical experience, and having a significant impact on the quality of medical services.

[0003] Currently, some existing patient transport devices lack an auxiliary turning mechanism after the patient has been transported, which means that multiple people need to work together to turn the patient when needed. However, the force used by multiple people to turn the patient can cause injury due to the force applied. At the same time, if there are not enough people, a single person cannot turn the patient, which reduces the practicality of the device. Utility Model Content

[0004] The purpose of this invention is to provide a patient transport device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patient transport device, comprising a transport cart and a connecting plate fixedly connected to the bottom perimeter of its inner cavity, and further comprising: A connecting seat is rotatably connected to the top of the connecting plate. A placement plate is fixedly connected to the top of the connecting seat, and an airbag for improving comfort is fixedly installed on the top of the placement plate. Pushing mechanisms installed on both sides of the inner cavity of the transfer vehicle can move the placement plate to assist in turning over. Both sides of the inner cavity of the transfer vehicle are equipped with inflation mechanisms to cushion and protect the airbags.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 As shown, a patient transport device includes a transport vehicle 1. Connecting plates 2 are fixedly connected to the bottom of the transport vehicle 1. The baffles on both sides of the transport vehicle 1 can provide shielding and protection. When placing a patient, the movable connection design will not obstruct the placement. The universal wheels around the bottom of the transport vehicle 1 facilitate the transport operation.

[0016] A connecting seat 3 is rotatably connected to the top of the connecting plate 2, and a placement plate 4 is fixedly connected to the top of the connecting seat 3. Rubber plates are fixedly connected to both sides of the placement plate 4. When pushing, the rubber plates are squeezed to facilitate the pushing operation. An airbag 5 for improving comfort is fixedly installed on the top of the placement plate 4. After the patient lies down, the small amount of gas in the airbag 5 can effectively improve comfort. Both sides of the inner cavity of the transport vehicle 1 are equipped with a pushing mechanism 6 that can push the placement plate 4 to move for assisted turning. Through the setting of the pushing mechanism 6, the connecting plate 2 and the connecting seat 3, the pushing mechanism 6 drives the placement plate 4 to tilt through the connecting plate 2 and the connecting seat 3, which can tilt the patient's body to assist in turning. A single person can turn the patient, reducing the waste of manpower and preventing multiple people from collaborating and causing injury to the patient's body due to force, etc. After tilting, it can be supported by locking with threads, making it convenient for the patient to lie on their side.

[0017] Both sides of the inner cavity of the transport vehicle 1 are equipped with inflation mechanisms 9 to cushion and protect the airbag 5. Through the setting of inflation mechanism 9 and airbag 5, the working mechanism 6 drives inflation mechanism 9 to inflate airbag 5. Airbag 5 can cushion the patient when turning over, prevent injury to the patient, improve the safety of assisted turning over, meet the needs of the user, and improve the comfort when lying on the side.

[0018] The pushing mechanism 6 includes a threaded rod 601 rotatably connected to both sides of the inner cavity of the transfer vehicle 1. A threaded plate 602 is threadedly connected to the outer surface of the threaded rod 601. Movable rods 603 are rotatably connected to both sides of the threaded plate 602. A movable plate 604 is rotatably connected to the top of one side of the movable rod 603. A handle 605 is fixedly connected to one side of the threaded rod 601. The top of the movable plate 604 is fixedly connected to the bottom of the placement plate 4. Through the pushing mechanism 6, the operator rotates the handle 605, which drives the threaded rod 601 to rotate. The threaded rod 601 moves the threaded plate 602, which in turn moves the movable plate 604 via the movable rods 603. The movable plate 604, through the connecting plate 2 and the connecting seat 3, moves the placement plate 4. The plate 4 can be tilted to assist the patient in turning over, meeting the user's needs. Furthermore, because the helix angle in the threaded rod 601 and the threaded plate 602 is smaller than the equivalent friction angle of the threaded surface, when the rotational force is removed, the reverse force generated by the load cannot overcome the friction between the threads to drive the threaded rod 601 to reverse, thereby achieving load positioning and locking. It can be supported by locking the threads after tilting, making it convenient for the patient to lie on their side. Correspondingly reducing the helix angle allows for the output of a larger axial thrust when the input torque is small, achieving a labor-saving effect and making it convenient for a single staff member to achieve the turning effect. As long as the helix angle is designed to be smaller than the equivalent friction angle (satisfying self-locking) and small enough (satisfying labor saving), labor saving and self-locking can be achieved simultaneously.

[0019] The inflation mechanism 9 includes an inflation cylinder 901 fixedly connected to both sides of the inner cavity of the transfer vehicle 1. A piston 902 is slidably connected to the inner surface of the inflation cylinder 901. A connecting rod 903 is fixedly connected to one side of the piston 902, and a push plate 904 is fixedly connected to the other side of the connecting rod 903. The bottom of the push plate 904 is fixedly connected to the top of the threaded plate 602. The top of the inflation cylinder 901 is connected to the inner cavity of the airbag 5 through a pipe. With the inflation mechanism 9, the threaded plate 602 moves while driving the push plate 904 to move. The push plate 904 pushes the connecting rod 903 and the piston 902 to move. The piston 902 can discharge the gas in the inflation cylinder 901 into the airbag 5 through the pipe for inflation. The airbag 5 can be inflated during assisted turning over, and the airbag 5 can provide cushioning and protection during turning over.

[0020] A support plate is fixedly connected to the bottom of the inner cavity of the transfer vehicle 1, and the two sides of the support plate are rotatably connected to one side of the threaded rod 601. The support plate can support the rotation of the threaded rod 601, making it more stable when rotating and effectively preventing tilting and jamming, thereby improving the stability of the operation of the push mechanism 6.

[0021] Guide grooves 8 are provided on both sides of the bottom of the inner cavity of the transfer vehicle 1. A guide block 7 is fixedly connected to the bottom of the threaded plate 602. The inner surface of the guide block 7 is slidably connected to the outer surface of the guide groove 8. Through the guide block 7 and the guide groove 8, the threaded plate 602 can maintain its movement effect, which facilitates the auxiliary turning work and improves the stability of the threaded plate 602 when it moves.

[0022] The top of the air cylinder 901 is connected to a telescopic hose. The telescopic hose allows for adjustment while assisting in turning over, so as not to interfere with the inflation mechanism 9 to inflate at the same time. It can provide inflation and cushioning protection while turning over.

[0023] It is worth noting that the technical features such as the transfer vehicle 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in the field. Furthermore, the structure is a lightweight design. This technical solution will not elaborate further.

[0024] Working principle: First, the side rails on both sides of the transport cart 1 are designed to be movable. When placing the patient, they can be moved horizontally. After the patient lies down, the small amount of gas in the airbag 5 can effectively improve comfort. Then, the universal wheels at the bottom facilitate transportation. Then, the operator turns the handle 605, which drives the threaded rod 601 to rotate. The threaded rod 601 drives the threaded plate 602 to move. The threaded plate 602 drives the movable plate 604 to move through the movable rod 603. The movable plate 604 drives the placement plate 4 to tilt through the connecting plate 2 and the connecting seat 3, which can tilt the patient's body to assist in turning over. It is convenient for one person to turn the patient over. The operator can turn one of the two push mechanisms 6 by turning the patient in the direction of turning over.

[0025] As the threaded plate 602 moves, it drives the push plate 904 to move. The push plate 904 pushes the connecting rod 903 and the piston 902 to move. The piston 902 can release the gas in the air cylinder 901 into the airbag 5 through the pipe for inflation. The airbag 5 can provide cushioning when turning over and improve the comfort when lying on the side.
