[0002] The purpose of medical air mattresses is to prevent pressure sores from forming or to prevent the further development of pressure sores. They are used for patients who need to be bedridden for a long time. Due to impaired consciousness or improper care, they cannot be turned over and patted on the back in a timely manner, resulting in long-term pressure on the local area without relief, which can lead to ischemia, necrosis and infection. For example, a smart air mattress based on clinical application is disclosed, with application number CN202420214264.6. This patent uses an air pump to control the inflation and deflation of the odd and even air bags through odd and even air intake pipes respectively. However, this air mattress cannot monitor the patient's microcirculation in real time, which affects the monitoring effect. It is also inconvenient to adjust the local air pressure according to the patient's body, and can only make global adjustments, which affects the comfort of the unpressurized areas and may even cause orthostatic hypotension. Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a microcirculation monitoring-based smear-type sensor-driven air mattress to overcome the defects of the prior art. Summary of the Invention

One end of the traction screw 403 is embedded in the bed board 1, and the inner wall of the bed board 1 is connected to the outer side of the traction screw 403 by threads. One end of the N-shaped frame 401 is rotatably connected to a positioning rotating frame 404. A support base plate 405 is snapped into the inside of the N-shaped frame 401.

Anti-slip textures are evenly distributed on the outer side of the turntable.
[0023] The support frame 409 and the connector 410 form a rigid support triangle structure. After the bed frame is tilted to a set angle, the sprocket 411 and the chain 412 lock the push position, effectively preventing the angle from shifting due to gravity.
[0024] The working principle and usage process of this invention are as follows: First, by utilizing the cooperation of the positioning bed frame 301, the movable bed frame 302 and the support plate 303, the air cushion frame 304 and the mattress 305 can be easily assembled on the bed board 1. At the same time, the gel sensor 306 is installed on the mattress 305 to facilitate subsequent monitoring. When in use, the patient lies on the mattress 305 with their body in contact with the gel sensor 306, allowing for real-time monitoring of the patient's microcirculation. In addition, the intelligent control processing terminal 314 controls the opening of the solenoid valves 309 inside all ventilation tubes 308 and controls the electric air pump 313 to allow outside air to enter the inflatable air cushion 307 through the air inflation tube 312, the connecting horizontal tube 311, the gas diversion tube 310, and the ventilation tube 308. After inflation is complete, the solenoid valves 309 are closed in time to increase the air pressure inside the inflatable air cushion 307, forcing the inflatable air cushion 307 to expand, thereby supporting the air cushion frame 304 and the mattress 305, facilitating long-term lying down for the patient and reducing the occurrence of pressure sores. Next, when the blood flow and oxygenation of the patient's body decrease, the information of the location is transmitted to the intelligent control processing terminal 314 through the gel sensor 306. After analysis and processing, the solenoid valve 309 below the local location is opened, and the electric telescopic rod 319 is retracted at the same time, which drives the sealing plug 320 to separate from the inner wall of the exhaust regulating cylinder 316, releasing the seal on the exhaust pipe 315 and facilitating the gas discharge. This allows the gas inside the inflatable air cushion 307 below the local location to be discharged through the vent pipe 308, the gas diversion pipe 310, another connecting horizontal pipe 311, and the exhaust pipe 315, reducing the air pressure inside the inflatable air cushion 307. After the requirements are met, the solenoid valve 309 is closed again, and the electric telescopic rod 319 is extended to push the sealing plug 320 to reseal the exhaust pipe 315. Next, the traction screw 403 is rotated to move the extension cam 402, the N-shaped frame 401 and the movable bed frame 302, so that a gap is created between the movable bed frame 302 and the positioning bed frame 301, which is convenient for subsequent angle adjustment. Then, the turntable drives the rotating shaft 413 to rotate, and through the cooperation of the driving gear 414 and the driven gear 415, the power is transmitted, driving the push rods 407 on both sides of the rotating shaft 413 to rotate. At the same time, through the cooperation of the transmission sprocket 411 and the chain 412, the power is further transmitted, so that the four push rods 407 inside the two rectangular slots 406 rotate synchronously, thereby pushing the push slider 408 to slide along the inner wall of the rectangular slot 406. Through the cooperation of the support frame 409, the movable bed frame 302 and the positioning rotating frame 404 are pushed to rotate along one end of the N-shaped frame 401. The tilt angle of the movable bed frame 302 is adjusted as needed to facilitate the patient to lie on the air mattress. Finally, when not in use, the rotating shaft 413 is reversed, and through the cooperation of the driving gear 414, driven gear 415, transmission sprocket 411 and chain 412, the push rod 407 is reversed, pulling the push slider 408 and support frame 409 to reset, so that the movable bed frame 302 is folded back to its original position. Then, the traction screw 403 is reversed to push the N-shaped frame 401 and extension plate 402 back to their original position, preventing gaps between the positioning bed frame 301 and the movable bed frame 302, and ensuring the patient's lying position.
