[0035] By arranging a plurality of universal roller structures 110 at the lower end of the bed frame 100, the movement of the emergency bed in this solution can be made more convenient.
[0036] The number of the bed boards 200 is set to two, and the two bed boards 200 are arranged in the front-rear direction.
[0037] The two bed boards 200 are connected by a hinge shaft 201 so that the two bed boards 200 are hinged to each other. And both ends of the hinge shaft 201 are rotatably connected to the bed frame 100 so that the two bed boards 200 can rotate around a fixed rotation axis relative to the bed frame 100.
[0038] An angle fixing structure is arranged between the two bed boards 200, and the angle fixing structure is used to fix or cancel the fixing of the included angle between the two bed boards 200. Specifically, in this embodiment, the number of the angle fixing structures is set to one. In other embodiments, the number of the angle fixing structures can also be set to two, and the two angle fixing structures are respectively arranged on both sides of the bed board 200. Those skilled in the art can select the number of the angle fixing structures according to actual needs.
[0039] Specifically, the angle fixing structure includes a guide shaft 310, a locking member 320, a swinging member 330, and a locking reset structure 340. The locking member 320 and the swinging member 330 are respectively installed on the two bed boards 200, and the locking member 320 and the swinging member 330 are arranged on the same side of the two bed boards 200.
[0040] Specifically, in this embodiment, the locking member 320 is fixedly connected to the rear bed board 200. The locking member 320 includes a locking portion and a connecting portion that are fixedly connected to each other. The connecting portion is arranged on the side of the locking portion away from the bed board 200. Both the locking portion and the connecting portion are set as cylindrical members, and the diameter of the connecting portion is smaller than that of the locking portion.
[0041] In this embodiment, the swinging member 330 is connected to the front bed board 200 through the guide shaft 310.

The locking grooves 331 are set to be multiple so that the angle fixing structure can be adapted to fix the two bed boards 200 at different angles.
[0047] When in the clamping position, the swinging member 330 is clamped with the locking part of the locking member 320. When in the disengaging position, the swinging member 330 cancels the clamping with the locking part of the locking member 320, so that the swinging member 330 can be easily driven by the staff to rotate, so that the angle limitation between the two bed boards 200 is cancelled, and the two bed boards 200 can be restored to the flat state.
[0048] When a supraventricular tachycardia patient needs to use the modified Valsalva maneuver for cardioversion, medical staff adjust the angles of the two bed boards 200 and finally fix the angles of the two bed boards 200 so that the patient lies semi-recumbent on this first aid bed and fixes the positions of the patient's lower limbs; then the patient blows air forcefully; when the patient's blowing reaches the specified pressure, the medical staff lift the bed board 200 at the back or press the bed board 200 at the front. Since the angle between the two bed boards 200 is fixed and both bed boards 200 are hinged to the bed frame 100, even a single medical staff can quickly change the patient's body position, raising the patient's lower limbs to the required angle. After the patient maintains the position of the raised lower limbs for 45 seconds, the medical staff drive the bed boards 200 again to rotate the two bed boards 200 simultaneously, turning the patient back to the semi-recumbent position. This first aid bed is simple to use and can assist the patient to complete the modified Valsalva maneuver independently without an assistant after use.
