At the same time, the cushion 3 and the railing 7 can also make it easy for the patient to lean on the backrest when getting up.

[0034] Working principle: When the patient needs to get up or use the toilet, the controller can push the movable end of the electric push rod 11 out. When the movable end of the electric push rod 11 extends, it will push the integrated mattress 10 located on the front side to flip, thereby assisting the patient to get up. At the same time, medical staff can use the guide rail 4 to slide the guardrail 5 to move the guardrail to a suitable position so that the patient can put their hands on the guardrail 5. The controller controls the movable ends of the two lowering electric cylinders 96 to descend, so that the support pad 93 moves down into the hollow groove between the soft pad 92 and the hard wooden frame 91. Then, the bidirectional linear module 94 drives the two support pads 93 to move away from each other to avoid the excrement outlet, so that the patient's excrement can fall smoothly into the feces collection device 6. The scissor fork mechanism drives the flush toilet 62 to rise, thereby aligning the flush toilet 62 ring with the excrement outlet of the toilet mechanism 9. After using the toilet, the flush toilet 62 pumps the excrement inside into the black water tank 64 through the pipeline, and at the same time, the clean water tank 63 is pumped into the flush toilet 62 through the pipeline.
