[0039] In this embodiment, the head and feet transfer flexible belt 54 and the body transfer flexible belt 48 are made of sheets or flat belts.

[0040] The working process of the embodiment of the present invention is as follows:

[0041] Taking the bidirectional patient transfer device to transfer a patient from left to right as an example, at this time, the body transfer flexible belt 48 will be completely wrapped around the first transfer synchronous belt 46 on the left, and only a little wrapped around the first transfer synchronous belt 46 on the right, and the head and foot transfer flexible belt 54 will be mostly wrapped around the head and foot transfer reel 53 on the left. The transfer process can be divided into four stages: the first stage: the two-way patient transfer device walks empty to the patient's side, during which the walking synchronous belt 38 of the walking mechanism rotates counterclockwise, and the body transfer flexible belt 48 and the head and foot transfer flexible belt 54 do not move; the second stage, when the patient is contacted, the two-way patient transfer device slowly transfers the patient to its upper surface, during which the head and foot transfer flexible belt 54 and the head and foot transfer flexible belt 54 rotate clockwise, and the walking synchronous belt 38 rotates counterclockwise; the third stage, the two-way patient transfer device carries the patient from left to right for transfer, during which the body transfer flexible belt 48 and the head and foot transfer flexible belt 54 do not move, and the walking synchronous belt 38 rotates clockwise; the fourth stage, the patient is put down, during which the body transfer flexible belt 48 and the head and foot transfer flexible belt 54 rotate counterclockwise, and the walking synchronous belt 38 rotates clockwise.

[0042] The whole transfer device is moved between the beds by the walking mechanism. When the patient's body is under the transfer device, the transfer flexible belt of the transfer mechanism uses friction and combines with the walking mechanism to continue to move under the patient's body to transfer to the transfer device, and then the walking mechanism moves in the opposite direction to transfer the patient to another bed. The posture of the patient will not change during the whole transfer process, and the transfer of the patient between the beds can be achieved smoothly. The power cabin 1 is respectively arranged at both ends, and two sets of relative walking mechanisms, body transfer mechanisms and head-foot transfer mechanisms with the same structure are arranged, so that the patient who originally lies obliquely can be adjusted. And the head and the upper part of the body use a common transfer motor 41, and the feet and the lower part of the body use the same transfer motor 41, so that the transfer of the body and the transfer of the head are synchronized, and no secondary damage is caused to the human body. The head-foot transfer flexible belt 54 and the body transfer flexible belt 48 are both made of flexible sheets and flat belts, which have good skin-friendliness and will not make the patient feel uncomfortable.

[0043] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
