When the patient needs a medical examination, it is convenient for temporary transfer.

[0042] Working principle:

[0043] When the device is in use, the limit bar 213 is used to limit the slide 212, and the slide 212 is slid on the slide groove of the storage rack 211 to drive the placement table 214 to slide out. The placement table 214 slides the ventilator body 215 out for operation, and the air supply pipe 224 is connected to the input port of the ventilator body 215. The oxygen cylinder 223 is placed on the oxygen cylinder bracket 222. The bracket 221 supports the oxygen cylinder bracket 222.

Then the mask connector 235 is connected to the mask part, and the slider 252 is slid forward to the front in the track 251, and then the support rod 253 is flipped upward. The support rod 253 flips upward to push the limit block 265, and the limit block 265 is pushed to the left by the support rod 253 to separate from the support rod 253, and the support rod 253 moves with After the bed board 11 is fitted and the support rod 253 moves to the rear side of the limit block 265, the spring 264 pulls the push block 263 so that the slide bar 262 drives the limit block 265 to limit the support rod 253, and the limit block 265 maintains the position of the support rod 253, and the extension frame 256 drives the delivery hose 233 to flip upward, and the end of the delivery hose 233, that is, the mask part, follows the extension frame 256 to flip to the top of the mattress 12, so that the extension frame 256 is flipped to the position roughly above the patient's face after the patient lies down, and the threaded rod 254 is driven to rotate in the support rod 253 by rotating the turntable 255, so that the turntable 255 can be away from the support rod 253, thereby making the flipped extension frame 256 rise, and the extension frame 256 drives the mask connector 235 to rise through the delivery hose 233, and the rising of the mask connector 235 drives the mask part to rise, which is convenient for adapting to the position and height of the patient.

[0044] When the delivery hose 233 moves, the delivery hose 233 will bend. At this time, the rotating sleeve 241 and the inner sleeve 243 rotate, and the connecting pipe 242 limits the rotation angle between the rotating sleeve 241 and the inner sleeve 243, so that the delivery hose 233 can bend within the range of the relative rotation angle between the rotating sleeve 241 and the inner sleeve 243. The delivery hose 233 will not bend excessively, thereby avoiding excessive bending of the delivery hose 233 to cause oxygen delivery to be blocked, and the limit block 265 supports the delivery hose 233, which is convenient for arranging, fixing and erecting the delivery hose 233. The interior of the delivery hose 233 is supported by the rotating sleeve 241, the connecting pipe 242 and the inner sleeve 243, which also avoids the delivery hose 233 being pressed and causing blockage, thereby improving the stability of oxygen delivery and avoiding the pipeline being pressed by the patient or other operators. The clamp 234 is used to reinforce the connection between the delivery hose 233 and the assembly head 232, and the delivery hose 233 and the mask connector 235, and the operation is simple.

[0045] After use, pull the push block 263 to drive the limit block 265 to the left, then flip the support rod 253 downward, and then slide the extension frame 256 backward in the track 251 to fold up the delivery hose 233 and place it under the bed, which reduces the space occupied and is also integrated with the bed body. When the patient needs a medical examination, it is convenient for temporary transfer. The bed board 11 can be moved directly by moving the bed legs 13, and the ventilator body 215 can be moved. The oxygen cylinder 223 is a temporary oxygen cylinder. When it is used normally in the ward, the air delivery pipe 224 can be connected to the large oxygen cylinder in the ward for oxygen supply.
