[0040] like Figures 1 to 6 As shown, the patient transfer device 100 according to an embodiment of the present application includes: a base 10 , a lifting assembly 20 , a receiving seat 30 and a moving assembly 40 .

[0041] Specifically, the lifting component 20 is provided on the base 10, and at least a part of the lifting component 20 is movable in the vertical direction. The receiving seat 30 is provided on the lifting component 20 so that the lifting component 20 can adjust the position of the receiving seat 30 in the vertical direction. The first side of the receiving seat 30 is provided with a storage groove 31 extending along the first direction, and the storage groove 31 is used to store the bed board 200. The side of the receiving seat 30 away from the base 10 is provided with a bearing surface 32, and the bearing surface 32 is used to support the bed board 200. The moving component 40 is provided on the receiving seat 30, and the moving component 40 can be switched between a first state and a second state, wherein, when the moving component 40 is in the first state, the moving component 40 moves the bed board 200 along the first direction at the height of the storage groove 31; when the moving component 40 is in the second state, the moving component 40 moves the bed board 200 along the first direction at the height of the bearing surface 32.

[0042] In other words, if Figure 1 As shown, the patient transfer device 100 according to an embodiment of the present application is mainly composed of a base 10, a lifting assembly 20, a receiving seat 30, and a moving assembly 40. The base 10 has moving wheels 11 at the bottom to facilitate movement. The lifting assembly 20 can be mounted on the upper side of the base 10. The lifting assembly 20 has a movable portion that can move in the vertical direction. The receiving seat 30 is mounted on the movable portion of the lifting assembly 20, so that the vertical position of the receiving seat 30 can be adjusted by the lifting assembly 20.

[0043] like Figure 1As shown, the first side of the receiving seat 30 can be any vertically arranged side, preferably a sidewall extending along the length of the receiving seat 30. The first direction is the horizontal direction, preferably the width direction of the receiving seat 30. The first side of the receiving seat 30 is provided with a storage slot 31 extending along the first direction. The bed board 200 can be inserted into the storage slot 31 from the first side of the receiving seat 30, and the bed board 200 can be stored through the storage slot 31. The side of the receiving seat 30 away from the lifting assembly 20, that is, the upper side of the receiving seat 30, is provided with a bearing surface 32, which is used to provide a support surface for the bed board 200. When transporting a patient, the bed board 200 supporting the patient is placed on the bearing surface 32, and the bearing surface 32 can support the bed board 200 supporting the patient, thereby enabling patient transport.

[0044] like Figure 1 As shown, at least a portion of the moving assembly 40 is movably disposed on the receiving seat 30 along a first direction, the moving assembly 40 is located between the bearing surface 32 and the storage tank 31, and the moving assembly 40 can switch between a first state and a second state. When the moving assembly 40 is in the first state, the moving assembly 40 can cooperate with the bed board 200 at the height of the storage tank 31, and can drive the bed board 200 to move along the first direction, so that the bed board 200 can move closer to or away from the storage tank 31; when the moving assembly 40 is in the second state, the moving assembly 40 can cooperate with the bed board 200 at the height of the bearing surface 32, at which time the lower side of the bed board 200 can be at the same height as the bearing surface 32, so that the bed board 200 can be transferred from the bed body to be transported to the bearing surface 32, or the bed board 200 can be transferred from the bearing surface 32 to the bed body to be transported, through the moving assembly 40.

[0045] like Figure 8 As shown, when a patient needs to be transferred, the vertical position of the supporting surface 32 is first adjusted by the lifting component 20 so that the supporting surface 32 and the lower side of the bed board 200 on the bed to be transferred are located at the same horizontal plane, and then the moving component 40 is switched to the second state so that the moving component 40 cooperates with the bed board 200 on the bed to be transferred, and the bed board 200 carrying the patient on the bed to be transferred is moved to the supporting surface 32 by the moving component 40, and finally the patient transfer device 100 is moved to one side of the target bed.

[0046] like Figure 7As shown, when a bed board 200 is placed on the target bed, the vertical position of the storage slot 31 is adjusted by the lifting assembly 20 so that the storage slot 31 and the bed board 200 on the target bed are at the same height, and then the moving assembly 40 is switched to the first state so that the moving assembly 40 cooperates with the bed board 200 on the target bed, and the bed board 200 on the target bed is moved into the storage slot 31 by the moving assembly 40, and then the height of the bearing surface 32 is adjusted, and the moving assembly 40 is switched to the second state so that the moving assembly 40 cooperates with the bed board 200 on the bearing surface 32, and finally the bed board 200 carrying the patient is moved to the target bed by the moving assembly 40.

[0047] Therefore, according to the patient transfer device 100 of the embodiment of the present application, the vertical position of the receiving seat 30 can be adjusted by the provided lifting component 20, so that the vertical position of the bearing surface 32, the storage slot 31 and the moving component 40 provided on the receiving seat 30 can be adjusted. The provided moving component 40 can move the bed board 200 carrying the patient to the bearing surface 32 to facilitate the transfer of the patient. When a bed board 200 is placed on the target bed, the bed board 200 on the target bed can be moved into the storage slot 31 through the moving component 40, and the bed board 200 carrying the patient can be moved to the target bed, which can improve the patient transfer efficiency; and the bed board 200 in the storage slot 31 can be moved to a bed without the bed board 200 through the patient transfer device 100, so as to facilitate the use of subsequent patients.

[0048] Furthermore, the lifting assembly 20 is at least one of an electric telescopic cylinder, a screw slider structure, and a telescopic frame structure.

[0049] According to one embodiment of the present application, a first mating hole 201 mating with the moving assembly 40 is provided on a first side of the bed board 200 , and a second mating hole 202 mating with the moving assembly 40 is provided on a second side of the bed board 200 .

[0050] Specifically, if Figure 5 and Figure 6 As shown, the side of the bed board 200 facing upward is the first side, and the side of the bed board 200 facing downward is the second side. The first side of the bed board 200 is provided with a first matching hole 201, and the second side of the bed board 200 is provided with a second matching hole 202. When the moving component 40 is in the first state, the moving component 40 can match with the first matching hole 201, and when the moving component 40 is in the second state, the moving component 40 can match with the second matching hole 202.

[0051] In some specific embodiments of the present application, the axis of the first matching hole 201 coincides with the axis of the second matching hole 202 .

[0052] In this embodiment, the axis of the first matching hole 201 coincides with the axis of the second matching hole 202, so that the movable component 40 can be matched with the bed board 200 at the same position in the horizontal direction. When in use, only the height of the movable component 40 needs to be changed.

[0053] According to one embodiment of the present application, a plurality of balls are embedded in the second side of the bed board 200. The balls can roll freely on the bed board 200. The bed board 200 can be supported by the balls. When the bed board 200 moves, the set balls can reduce the friction with the contact surface, making it more convenient to move the bed board 200.

[0054] In some specific embodiments of the present application, a side of the receiving seat 30 away from the lifting assembly 20 is provided with a slide groove 33 extending along the first direction, and the slide groove 33 is connected to the storage slot 31. The moving assembly 40 includes: a movable part 41 and a transmission column 42. The movable part 41 is movably provided in the slide groove 33 along the first direction, and the transmission column 42 is movably provided in the movable part 41 between the first position and the second position along the vertical direction. When the transmission column 42 is in the first position, the first end of the transmission column 42 cooperates with the first matching hole 201, and the moving assembly 40 is in the first state. When the transmission column 42 is in the second position, the second end of the transmission column 42 cooperates with the second matching hole 202, and the moving assembly 40 is in the second state.

[0055] That is to say, if Figure 1 and Figure 3 As shown, the bearing surface 32 is provided with a slide groove 33 extending along a first direction, and the slide groove 33 penetrates the upper wall surface of the storage slot 31, so that the slide groove 33 is connected to the storage slot 31. The movable assembly 40 is movably disposed in the slide groove 33 along the first direction. Specifically, the movable assembly 40 mainly consists of a movable member 41 and a transmission column 42. The movable member 41 is movably disposed in the slide groove 33 along the first direction. The axis of the transmission column 42 is in the vertical direction. The transmission column 42 is movably disposed in the movable member 41 along the vertical direction between a first position and a second position.

[0056] like Figure 2 and Figure 6 As shown, the first end of the transmission column 42 faces downward, and the second end of the transmission column 42 faces downward. When the transmission column 42 is in the first position, the moving assembly 40 is in the first state, and the first end of the transmission column 42 can extend into the first matching hole 201 to cooperate with the first matching hole 201; when the transmission column 42 is in the first position, the moving assembly 40 is in the second state, and the second end of the transmission column 42 can extend into the second matching hole 202 to cooperate with the second matching hole 202.

[0057] like Figure 7As shown, when the bed board 200 is moved at the height of the storage slot 31, the transmission column 42 is in the first position, and the first end of the transmission column 42 cooperates with the first matching hole 201; when the bed board 200 is moved at the height of the bearing surface 32, the transmission column 42 is in the second position, and the second end of the transmission column 42 cooperates with the second matching hole 202.

[0058] According to one embodiment of the present application, the transmission column 42 is provided with a first tooth portion 421 extending in the vertical direction, and the moving component 40 also includes: a first gear 43 and a first motor 44, the first gear 43 is engaged with the first tooth portion 421, the first motor 44 is provided on the movable part 41, and the output end of the first motor 44 is connected to the first gear 43 to drive the first gear 43 to rotate.

[0059] Specifically, if Figure 2 and Figure 6 As shown, the supporting movable member 41 is formed as a slider structure, a driving cavity is provided inside the movable member 41, and the movable member 41 is also provided with a mounting hole passing through the driving cavity. The transmission column 42 is movably provided in the mounting hole along the vertical direction, and a part of the transmission column 42 located in the driving cavity is provided with a first tooth portion 421 extending along the vertical direction. A first motor 44 is fixedly connected in the driving cavity. The first motor 44 is preferably a servo motor. The output end of the first motor 44 is fixedly connected to the first gear 43, and the first gear 43 is engaged with the first tooth portion 421.

[0060] When the state of the moving component 40 needs to be switched, the first motor 44 can be controlled to operate, and the first motor 44 can drive the first gear 43 to rotate. The rotation of the first gear 43 drives the transmission column 42 to move in the vertical direction through the first tooth portion 421, thereby realizing the state switching of the moving component 40.

[0061] In addition, the transmission column 42 can also be driven by a telescopic structure such as an electric telescopic rod. The driving structure of the transmission column 42 can be selected according to actual needs, and the transmission column 42 can also be replaced with an electric telescopic rod. This application is not limited.

[0062] Furthermore, if Figure 6 As shown, a portion of the transmission column 42 located in the installation cavity 203 is provided with a mating surface extending in the vertical direction, and the installation cavity 203 is provided with a limiting surface extending in the vertical direction. The mating surface fits with the limiting surface, thereby preventing the transmission column 42 from rotating around its own axis.

[0063] In some specific embodiments of the present application, the moving component 40 also includes: at least one threaded rod 45 and a driving member 46, the threaded rod 45 extends along a first direction, the threaded rod 45 is rotatably arranged in the slide groove 33 around its own axis, the movable member 41 is threadedly connected to the threaded rod 45, the driving member 46 is arranged on the receiving seat 30, and the driving member 46 is connected to the threaded rod 45 to drive the threaded rod 45 to rotate around its own axis.

[0064] That is to say, if Figure 1 and Figure 3 As shown, the supporting movable member 41 is provided with two threaded holes passing through in the first direction, and the two threaded holes are respectively threadedly connected to a threaded rod 45, and the two ends of the threaded rod 45 are respectively rotatably connected to the receiving seat 30, and the first end of the threaded rod 45 passes through the receiving seat 30, and one side of the receiving seat 30 is fixedly connected to a driving member 46, which can be a servo motor. The driving member 46 and the first end of the threaded rod 45 are connected through a gear set. The gear set can be driven to rotate by the driving member 46, and the rotation of the driving member 46 can drive the threaded rod 45 to rotate around its own axis, thereby driving the movable member 41 to move along the first direction.

[0065] In addition, the movable part 41 can also be driven by a driving structure such as a sprocket chain structure, a telescopic cylinder, etc., which can be selected according to actual needs and is not limited in this application.

The patient transfer device 100 also includes: a limiting assembly 50 and a transmission assembly 60.

[0067] Specifically, the limit assembly 50 is movably arranged in the installation cavity 203 between the extended state and the retracted state. The limit assembly 50 is provided with a limit portion 51. When the limit assembly 50 is in the extended state, the limit portion 51 extends out of the connecting groove 204 and cooperates with the first limit groove 321. When the limit assembly 50 is in the retracted state, the limit portion 51 disengages from the first limit groove 321. The transmission assembly 60 is arranged in the installation cavity 203. The transmission assembly 60 is transmission-connected to the limit assembly 50. The transmission assembly 60 is provided with a matching portion 611. The matching portion 611 corresponds to the position of the first matching hole 201 and / or the second matching hole 202. The transmission column 42 cooperates with the matching portion 611 to switch the limit assembly 50 from the extended state to the retracted state.

[0068] That is to say, if Figure 5 and Figure 6As shown, the storage slot 31 can be provided with a first limiting slot 321 on the side close to the lifting assembly 20, and the bearing surface 32 can also be provided with a first limiting slot 321.
