[0022] Embodiment 1: Refer to Figures 1-3 , an examination bed, including a bed board 1, a first groove 2 is opened at the upper end of the bed board 1, and a headrest mechanism 3 for neck support is connected to the first groove 2;

[0023] The headrest mechanism 3 includes an airbag pillow assembly 31, the airbag pillow assembly 31 is detachably connected to the first groove 2, the bottom end of the bed board 1 is fixedly connected with an open box 32, a piston plate 34 is slidably and sealingly connected in the open box 32, a chamber 33 is formed between the piston plate 34 and the open box 32, an electric telescopic rod 35 for driving the piston plate 34 to move is connected to the bed board 1, a connecting pipe 36 is communicated with the chamber 33, and the other end of the connecting pipe 36 is inserted into the airbag pillow assembly 31.

[0024] Working process:

[0025] During the examination, the person lies on the bed board. When the height of the airbag pillow assembly 31 is relatively low, the electric telescopic rod 35 drives the piston plate 34 to move away from the electric telescopic rod 35. After the piston plate 34 moves, the volume of the chamber 33 is reduced, the internal pressure of the chamber 33 increases, so that the gas inside the chamber 33 is introduced into the airbag pillow assembly 31 through the connecting pipe 36, and the support height of the airbag pillow assembly 31 is increased;

[0026] When the height of the airbag pillow assembly 31 is relatively high, the electric telescopic rod 35 drives the piston plate 34 to move towards the electric telescopic rod 35. After the piston plate 34 moves, the volume of the chamber 33 is increased, the internal pressure of the chamber 33 is reduced, so that the gas inside the airbag pillow assembly 31 is introduced into the chamber 33 through the connecting pipe 36, and the support height of the airbag pillow assembly 31 is reduced. The support height of the airbag pillow assembly 31 can be adjusted as needed, which is convenient for supporting different patients, improves the comfort of the examination, enables the patient not to move the body due to uncomfortable support during the examination, and improves the examination effect.

[0027] Embodiment 2: In Embodiment 1, when the airbag pillow assembly 31 is used to support the patient's head and neck, it is not convenient to remove the airbag pillow assembly 31 for replacement. Refer to Figures 4-5, as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that the airbag pillow assembly 31 includes a mounting plate 311. The mounting plate 311 is snap-connected to the first groove 2. A second groove 312 is formed at the upper end of the mounting plate 311. An airbag pillow 313 is connected in the second groove 312. A sterilizing cloth layer is provided at the upper end of the airbag pillow 313. A through hole 314 is formed at the bottom end of the mounting plate 311. The through hole 314 communicates with the airbag pillow 313 and also communicates with the connecting pipe 36. A sealing ring 315 is connected in the through hole 314. The sealing ring 315 is in contact with the connecting pipe 36. Pull the mounting plate 311 upward to separate the mounting plate 311 from pushing against the first groove 2. After the mounting plate 311 moves upward, it is separated from the connecting pipe 36. Then, the airbag pillow 313 can be removed from the mounting plate 311 for replacement, which is convenient for replacement.

[0028] Embodiment 3: In Embodiment 1, when the patient lies on the bed board 1 for examination, the patient is likely to move around, thus reducing the examination effect. Refer to Figure 1 , as another preferred embodiment of the present utility model, the difference from Embodiment 1 is that two parallel limiting mechanisms 4 are connected to the upper end of the bed board 1.

After the patient lies on the bed board 1, the elastic band 41 is pulled by the clamping block 42. After the clamping block 42 is snapped into the clamping groove 43, the elastic band 41 is in a taut state. The taut elastic band 41 squeezes and limits the patient to prevent the patient from moving around. At the same time, airbag strips 44 are provided between the elastic band 41 and the patient to reduce the friction of the elastic band 41 on the patient.

[0029] The above is only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto.
