The other ends of the two groups of straps 51 on the surface of the first bed board 3 are fixedly connected to the connecting belt 71. A fixed shell 72 is fixedly installed at the bottom of the first bed board 3. A first servo motor 73 is fixedly installed inside the fixed shell 72. The output end of the first servo motor 73 is fixedly connected to the driving gear 74. Two groups of guide wheels 75 are connected inside the fixed shell 72 so as to rotate symmetrically around the driving gear 74. The other end of the connecting belt 71 is connected to the guide wheel 75. The rear ends of the two groups of guide wheels 75 are fixedly connected to the driven gear 76. The driven gear 76 and the driving gear 74 are meshed with each other. Detection assemblies 77 are provided on the left and right sides of the first bed board 3. Figure 2 As shown, this structure is used to drive the driving gear 74 to rotate by starting the first servo motor 73. Under the action of the mutual engagement of the driving gear 74 and the driven gear 76, the driven gear 76 drives the guide wheel 75 to rotate. When the guide wheel 75 rotates, it pulls the connecting belt 71 to shrink, controls the length of the connecting belt 71, and adjusts the range of motion of the patient's legs. It can also be used in conjunction with the convenient mechanism 8 to open the patient's legs.

[0025] Furthermore, a protective assembly 9 is provided at the bottom of the second bed board 4. The protective assembly 9 includes a rotating shaft 91, a pad 92, a head fixing belt 93, a pneumatic push rod 94 and a connecting piece 95. The first bed board 3 and the second bed board 4 are rotatably connected via the rotating shaft 91. The surface of the second bed board 4 is connected to the pad 92. The outer side of the pad 92 is connected to the head fixing belt 93. Two sets of pneumatic push rods 94 are installed on the upper end of the bottom plate 2. Two sets of connecting pieces 95 are connected to the lower end of the second bed board 4. The output end of the pneumatic push rod 94 is rotatably connected to the connecting piece 95. Figure 4 As shown, the structure is used to place the patient's head on the pad 92, then fix the patient's head through the head fixing belt 93, fix the torso through the torso fixing belt 6, start the pneumatic push rod 94, and push the second bed board 4 to rotate under the action of the rotating shaft 91 to prevent a series of problems such as aspiration and suffocation caused by sputum or reflux when the patient is restrained.

[0026] Furthermore, a set of straps 51 on the surface of the first bed board 3 is connected to a leg fixing strap 55, an electromagnetic buckle 56 is fixedly installed at the end of the leg fixing strap 55, and an adaptive buckle is installed on the other set of straps 51. Figure 6 As shown, after the legs are fixed by the restraint assembly 5, the electromagnetic buckle 56 at the leg fixing belt 55 can be fitted with the buckle to fix the legs.

[0027] Furthermore, the detection assembly 77 includes a fixing frame 771 and a pressure sensor 772. The fixing frame 771 is fixedly connected to the left and right sides of the first bed board 3. The pressure sensors 772 are installed inside the left and right sides of the first bed board 3. The pressure sensors 772 are located inside the fixing frame 771. The pressure sensors 772 are electrically connected to the first servo motor 73. The connecting belt 71 passes between the fixing frame 771 and the pressure sensor 772. Figure 7 As shown, the structure is used to pass through the fixing frame 771 and the pressure sensor 772 through the connecting belt 71. When the patient is excited and agitated, the connecting belt 71 is pulled, and the pressure sensor 772 is squeezed during the pulling process, so that the pressure sensor 772 is monitored in real time. When the monitoring data exceeds the specified range, a signal is sent to the first servo motor 73 to start the first servo motor 73 and reduce the range of movement of the patient's legs.

[0028] Furthermore, a fixing groove 10 is provided inside the first bed board 3, an inserting plate 11 is inserted inside the fixing groove 10, and a handle 12 is fixedly connected to the left side of the inserting plate 11. Figure 5 As shown, the structure is used to insert the inserting plate 11 into the fixing groove 10 by holding the handle 12, thereby blocking the hole at the first bed board 3 and improving the comfort of the patient.

[0029] Working principle: When used, Figure 1 and Figure 6 As shown, the patient lies on the first bed board 3 and the second bed board 4, and the patient's limbs are placed in the corresponding sponge pads 53 respectively, and then the hook surface of the Velcro 52 passes through the limit block 54 and fits with the plush surface of the Velcro 52 to fix the patient's limbs, and then the electromagnetic buckle 56 at the leg fixing belt 55 is fitted with the buckle to fix the legs, as shown in FIG. Figure 4 and Figure 5 As shown, the patient's head is placed on the pad 92, and then the patient's head is fixed by the head fixing belt 93, and the torso is fixed by the torso fixing belt 6, as shown in FIG. Figure 2 and Figure 7 As shown, the first servo motor 73 is started to drive the driving gear 74 to rotate. Under the action of the mutual engagement of the driving gear 74 and the driven gear 76, the driven gear 76 drives the guide wheel 75 to rotate, thereby controlling the length of the connecting belt 71 and adjusting the range of motion of the patient's legs. When the patient is excited and agitated, the connecting belt 71 is pulled, and the pressure sensor 772 is squeezed during the pulling process. The pressure sensor 772 is monitored in real time. When the monitoring data exceeds the specified range, a signal is sent to the first servo motor 73 to start the first servo motor 73, so that the driving gear 74 rotates in the opposite direction, and the Velcro 52 is attached to the fixing frame 771. It can also be used in conjunction with the convenient mechanism 8 to open the patient's legs. Figure 3 and Figure 5As shown, when the patient needs to urinate or defecate, he first holds the handle 12 to disengage the inserting plate 11 from the fixing groove 10, so that the hole at the first bed board 3 is opened, and at the same time, a garbage bag is put on the bottom of the fixing tube 84 or a basin is placed on the bottom of the fixing tube 84, and then the second servo motor 81 is started to drive the driving wheel 82 to rotate, so that the synchronous belt 83 drives the driven wheel 85 to rotate. When the driven wheel 85 rotates, the internal gear 86 and the small gear 87 inside the driven wheel 85 engage with each other, driving the six groups of connecting rods 88 and the baffle 89 to rotate synchronously, thereby opening the fixing tube 84 and positioning the patient's buttocks above the fixing tube 84, solving the problem of urination and defecation. Figure 4 As shown, the pneumatic push rod 94 is started to push the second bed board 4 to rotate under the action of the rotating shaft 91 to prevent sputum or reflux from causing aspiration, suffocation and other problems when the patient is restrained. The above is the entire working principle of the present invention.
