[0015] 1. Pour food into the inner cup and crush it with the crushing paddle to make liquid food. Liquid food is easy to make. The water in the outer cup can be heated by the heating base to heat the food in the inner cup in a water bath. After the feeder is installed on the catheter, the rotating drum can be driven to rotate to introduce the liquid food into the stomach tube for feeding under the rolling of the two pressing wheels, or gastric juice can be drawn out for observation. The operation is relatively convenient and the feeding speed is controllable.

[0016] 2. After feeding, take out the inner cup, increase the output power of the heating base to make the water in the outer cup boil, and then sterilize and clean the space in the outer cup and the crushing paddle at high temperature for the next use. When cleaning the residual food in the catheter, place one end of the catheter in the outer cup and start the water supply to absorb water to clean the catheter, which is more convenient to use;

[0017] 3. Turn the push plate to rotate the threaded cylinder, and pull the traction rope through the traction frame to drive the T-shaped connecting frame to move, so that the two pressing wheels can be retracted to the middle. At the same time, the pressing wheels are tilted under the guidance of the wedge platform, so that the catheter can be easily inserted between the pressing wheel and the base, which is convenient for installation and disassembly.

Figure 4Then, the movable plate 52 is rotated to make the clamping protrusion 521 press the branch tube 41, and the driving motor 30 is controlled to rotate in the opposite direction to extract the gastric tube through the gastric tube 4 for inspection, and the gastric fluid is stopped when the gastric fluid moves to the branch tube 41, and then the movable plate 52 is rotated to make the clamping protrusion 521 press the gastric tube 4 between the branch tube 41 and the patient to prevent the gastric fluid from falling back, and then the driving motor 30 is started to rotate forward to extract the liquid food in the inner cup 16 through the catheter 2 to the branch tube 41 and stop, and the movable plate 52 is rotated again to make the clamping protrusion 521 press the branch tube 41 and then the driving motor 30 is started to rotate forward again to inject the liquid food and gastric fluid into the patient's stomach. It is easy to use, and the air in the catheter 2 and the gastric tube 4 can be discharged from the branch tube 41, and a large amount of air will not be injected into the patient's stomach. At the same time, the speed of liquid food injection can be controlled by controlling the speed of the driving motor 30. During the process of drawing gastric fluid for observation and drawing liquid food, part of the gastric fluid or liquid food can flow into the collecting bottle 53 from the branch tube 41 to avoid contaminating the ward.
