[0034] The monitoring bed 1 is equipped with multiple monitoring devices (not shown). These include a robotic arm for nursing care, which assists in placing devices such as patches on the patient's body, monitors the patient's heart rate, blood pressure, and other parameters, and issues an alarm when an abnormality is detected. Furthermore, the second and third nursing beds 3 and 4, like the first nursing bed 2, are equipped with an electric push rod 19, a rotating pad 24, and an adjustable pad 25. Adjacent rotating pads 24 are connected by soft pads, making the patient's reclining position more comfortable.

[0035] The patient lies on the nursing bed and when he needs to turn over, he starts the corresponding electric push rod 19. Figure 8 As shown, the electric push rod 19 with the driving roller 21 moves upward, the adjusting frame 9 rotates, and the patient lies in the middle of the bed by default. During the rotation of the adjusting frame 9, the patient will be pushed to turn over. When the electric push rod 19 is started, the electromagnet 29 will also be started. After the electromagnet 29 is started, it attracts the metal sheet 30. Under the action of magnetic force, the slide plate 28 drives the adjusting rod 27 to move upward, thereby driving the first piston tube 17 to move upward, and the first piston rod 18 drives the rack 16 to move upward, so that the rack 16 and the gear 15 can engage. The electric push rod 19 drives the second piston rod 23 to move upward, and the second piston rod 23 moves to the outside of the second piston tube 22. Part of the air in the second piston tube 22 enters the first piston tube 17, and the first piston rod 18 moves into the first piston tube 17. The first piston rod 18 drives the rack 16 to slide, driving the gear 15 to rotate, and driving the adjusting roller 10 to rotate through the transmission wheel, thereby driving the rotating pad 24 to move. On the one hand, the bottom is used to assist the patient in turning over, and on the other hand, the patient will not move to the edge of the bed when turning over.

[0036] refer to Figures 1-10, an auxiliary support assembly, including an adjustment pad 25 arranged on the rotating pad 24, a plurality of adjustment air bags 32 are provided in the adjustment pad 25, a diversion chamber 33 is provided in the adjustment pad 25, and when the adjustment frame 9 rotates, the air in the diversion chamber 33 enters the adjustment air bag 32, and the adjustment air bag 32 is disconnected from the diversion chamber 33 when it is squeezed, a connecting hole 36 is provided on the bottom wall of the adjustment air bag 32, a plurality of connecting pipes adapted to the connecting hole 36 are provided on the top wall of the diversion chamber 33, a fixing frame 35 is provided on the top wall of the adjustment air bag 32, a sealing plate is fixedly installed on the bottom wall of the fixing frame 35, and the size of the sealing plate is larger than the connecting hole 36, an air inlet hole 34 is provided at the bottom end of the adjustment pad 25, and the air inlet hole 34 and the first A second connecting tube is connected between the two piston tubes 22, and a fixed tube 37 is provided on the top wall of the adjusting airbag 32, and the fixed tube 37 passes through the top wall of the adjusting airbag 32, and a plurality of water-absorbing beads are provided in the fixed tube 37. A heat dissipation rod 38 is movably inserted at the bottom end of the fixed tube 37, and a connecting rod 39 is fixedly installed at the bottom end of the heat dissipation rod 38, and a pull-down plate 40 is fixedly installed at the top end of the connecting rod 39, and the pull-down plate 40 is fixedly connected to the inner top wall of the adjusting airbag 32, and water-absorbing cotton is provided at the top of the fixed tube 37, and a plurality of ventilation holes are provided on the adjusting pad 25. One end of the second nursing bed 3 is fixedly connected to two connecting plates 5, and a telescopic rod 6 is fixedly installed on one side of the connecting plate 5, and a pillow 7 is fixedly installed on the end of the telescopic rod 6 away from the connecting plate 5.

[0037] After the second piston rod 23 moves upward, the air in the second piston tube 22 enters the shunt chamber 33 through the second connecting tube. During the patient's turning over, the side of the patient's back will squeeze part of the regulating airbag 32 in the regulating cushion 25, while the part near the spine will not squeeze the regulating airbag 32. The fixing frame 35 in the squeezed regulating airbag 32 will be squeezed, and the sealing plate below the fixing frame 35 will block the connecting hole 36, preventing the regulating airbag 32 from communicating with the shunt chamber 33. The connecting hole 36 in the regulating airbag 32 that is not squeezed is not blocked, and the air in the shunt chamber 33 enters the regulating airbag 32. After the regulating airbag 32 expands, it props up the regulating cushion 25, thereby supporting the patient's entire back, improving the patient's comfort, reducing the burden on the patient's body, and helping the patient recover.

[0038] When the patient sweats on his back, the sweat enters the fixed tube 37 through the through hole, the water-absorbing beads absorb the sweat and expand, pushing the connecting rod 39 downward, pulling the pull-down plate 40 downward, and the pull-down plate 40 drives the top of the adjusting airbag 32 to reduce the contact area between the adjusting airbag 32 and the top of the adjusting pad 25 and the patient's back skin, so that external air can enter these gaps to help dissipate heat from the patient's back, which is more comfortable for the patient in hot summer weather.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
