[0002] Medical feeding bags are plastic bags that can temporarily store the nutrient solution needed by patients and deliver the nutrient solution to patients through an infusion tube. For patients with gastrointestinal damage and those who are unable to chew and eat normally after surgery, the nutrient solution can be delivered to the patient through a feeding bag.

[0003] In the related art, a disposable feeding bag includes a bag body, a discharge tube and an adjusting ball. One end of the discharge tube is fixedly connected to the bag body, and the other end is connected to a feeding tube inserted into the patient's body. The nutrient solution is poured into the bag body of the feeding bag, and then the bag body is hung. The nutrient solution in the bag body is slowly discharged through the discharge tube by gravity and enters the feeding tube to provide supply to the patient. The nursing staff manually fluctuates the adjusting ball and judges the current flow rate based on experience.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: different types of patients have different conditions and needs, and the flow rate can only be adjusted by adjusting the adjustment ball based on the nursing staff's experience, which causes the current flow rate to deviate from the flow rate that the patient can accept, causing discomfort to the patient and even causing the patient to choke.

When the third connecting block 44 is inserted into the connection notch, the abutment block 43 abuts against the first connecting block 2123 and the second connecting block 312. At this time, after the pressure sensor detects the pressure, it sends a signal to the heater. After receiving the signal, the heater starts, so that the heating block 31 gradually heats up, which is convenient for keeping the nutrient solution in the discharge pipe 13 warm.

[0053] Then the nursing staff rotates the control block 41, which drives the control rod 411 and the control gear 412 to rotate, and the control gear 412 drives the first transmission wheel 2112 and the transmission shaft 2111 to rotate, and the transmission shaft 2111 drives the second transmission wheel 2113 to rotate, and then the second transmission shaft 2111 drives the adjustment gear 521 to rotate.
