[0028] After the basic positioning is completed, first hold the pull handle 63 fixedly installed on the sealing cover 62, exert upward force to remove the sealing cover 62 from the top end of the quantitative food storage bin 61, then inject the liquid or semi-liquid food suitable for the patient to eat after surgery into the quantitative food storage bin 61 made of transparent glass, control the food injection amount by means of the scale mark 68 provided on the outer wall of the quantitative food storage bin 61, to avoid too much food from spilling or too little food from needing frequent supplement, after the food injection is completed, accurately buckle the sealing cover 62 on the top end of the quantitative food storage bin 61 to realize the sealing protection of the quantitative food storage bin 61, to prevent food pollution and rapid temperature loss, then start the micro peristaltic pump 66 assembled on the sealing cover 62, the food in the quantitative food storage bin 61 is sucked under the negative pressure of the micro peristaltic pump 66, enters the internal passage of the sealing cover 62 through the inlet pipe 64 fixedly installed in the internal input end of the sealing cover 62, is transported to the input end of the micro peristaltic pump 66 through the outlet pipe 65 fixedly installed in the output end of the sealing cover 62, is transported by the hose 69 fixedly installed at the other end of the micro peristaltic pump 66 after being pressurized by the micro peristaltic pump 66, and is finally guided out through the flexible silica gel feeding pipe 610 fixedly installed at the other end of the hose 69. The patient inserts the teeth into the arc-shaped bite groove 612 provided in the bite positioning sleeve 611 sleeved on the flexible silica gel feeding pipe 610, to realize the precise positioning of the mouth and the feeding pipe, and at the same time, the flow rate adjusting knob 67 on the micro peristaltic pump 66 can be manually adjusted according to the swallowing ability in the postoperative recovery stage of the patient, to change the operating power of the micro peristaltic pump 66 and further adjust the food conveying rate, to avoid the rate being too fast to cause choking, irritation of the wound, and the rate being too slow to affect the eating efficiency, to realize convenient and safe self-feeding.

[0029] In the working process of the drainage assembly 6, the auxiliary assembly 7 synchronously improves the stability, comfort and hygiene of the lifting device. Two groups of support frames 71 in the auxiliary assembly 7 are fixedly installed on the two groups of buckles 4 respectively. Each support frame 71 is fixedly assembled with a support rod 72. The bottom end of the support frame 71 and the support rod 72 are tightly attached to the bottom surface of the arc-shaped frame 5, forming a multi-point support structure, which effectively improves the stability of the arc-shaped frame 5 and the internal quantitative food storage bin 61, and avoids food spilling due to slight shaking of the device during eating. Four groups of anti-skid bases 73 are fixedly installed at the bottom of the support frame 1. Each anti-skid base 73 is fixedly attached with an anti-skid rubber pad 74 with anti-skid lines at the bottom end. By increasing the friction between the device and the placement surface, the device is effectively prevented from shifting during use, further enhancing the stability of the overall structure. The heater 75 fixedly installed inside the arc-shaped frame 5 can work with the temperature sensor on the outer wall of the quantitative food storage bin 61.

Then the rotating rod 711 fixedly installed inside the rectangular block 79 is rotated by damping, driving the V-shaped elastic sheet 712 fixedly installed at the other end of the rotating rod 711 to adjust the orientation. By utilizing the elastic deformation characteristics of the V-shaped elastic sheet 712, it can fit the head profile of different patients to achieve stable support, reducing the stress on the patient's neck. The disposable antibacterial coating pad 713 pasted on the V-shaped elastic sheet 712 can be replaced in time after each use, effectively preventing cross infection and ensuring the safety of use, and improving the practicality of the device.

[0030] The adjusting assembly 8 further improves the adaptability of the device to different patients. Two groups of vertical rods 81 of the adjusting assembly 8 are respectively rotationally installed on two groups of support rods 72. Each group of vertical rods 81 is provided with a fixed clamp 82 at the top end, which is tightly clamped at the top end of the arc-shaped frame 5 to form a symmetrical fixed structure, thereby improving the installation stability of the vertical rods 81 and indirectly improving the overall firmness of the arc-shaped frame 5. The top end of the vertical rod 81 is further provided with a fixed block 83, and the hose 69 is arranged through the internal passage of the fixed block 83. When it is necessary to manually fine-tune the food conveying rate, the screw rod 84 inside the fixed block 83 is manually rotated. The screw rod 84 rotates while moving horizontally along the horizontal direction under the action of the screw thread, and the hose 69 passing through the screw rod 84 is flexibly clamped and extruded through the cooperation of the end of the screw rod 84 and the inner wall of the fixed block 83, thereby changing the cross-sectional area of the internal passage of the hose 69, and further assisting in adjusting the conveying rate of the food in the hose 69. The flow rate adjusting knob 67 forms a double rate adjusting mechanism, which is suitable for the eating needs of different patients and significantly improves the adaptability of the device. After the eating operation is completely finished, the drainage assembly 6 needs to be cleaned and disinfected. The cleaning and disinfecting water is injected into the internal passage of the feeding pipe 64, and the miniature peristaltic pump 66 is started to drive the disinfecting water to circulate in the feeding pipe 64, the discharging pipe 65, the hose 69 and the flexible silica gel feeding pipe 610, so as to clean and disinfect the inner wall of each pipe, avoid the breeding of bacteria caused by residual food, and ensure the health and safety of the device in the next use.
