The upper connecting tube 34 is arranged above the positioning plate 31, and the upper connecting tube 34 is connected to the lower connecting tube 33; the funnel 4 includes a tube body 41 and a bucket body 42, the tube body 41 is arranged at the bottom of the bucket body 42, the tube diameter of the tube body 41 is smaller than the tube diameter of the upper connecting tube 34, and a cavity is formed in the bucket body 42.

[0031] Thus, the autonomous feeder of the utility model, when in use, inserts the cannula 1 from the patient's mouth into the patient's esophagus, and then places the mouth pad 2 in the patient's mouth so that the cannula 1 is located in the yield cavity of the mouth pad 2, and then installs the positioning connector 3 on the mouth pad 2 so that the positioning insert 32 abuts against the outside of the mounting seat 23, thereby fixing the positioning connector 3 on the mouth pad 2 to prevent the positioning connector 3 from shaking, and finally inserts the tube body 41 of the funnel 4 into the upper connecting tube 34. When the patient is feeding autonomously, the nutrient solution is placed in the funnel 4, and the nutrient solution enters the cannula 1 along the funnel 4, and finally enters the esophagus along the cannula 1, so that there is no need for indwelling nasogastric feeding and gastrostomy, which improves the patient experience.

[0032] In this embodiment, the cannula 1 can be a "gastric lavage tube" with a diameter of 9.33 cm and a model of 28FR, and can be used to feed semi-fluids with particles. As an embodiment, for an adult of about 170 cm, the cannula 1 can be about 30 cm long, with 10 cm exposed outside the oral cavity and 20 cm located inside the body, so that the lower end of the cannula 1 is only 3-5 cm below the esophageal opening, maintaining the original peristaltic physiological function of the esophagus from top to bottom, effectively and significantly reducing esophageal reflux, and can feed semi-fluids with particles.

[0034] By providing the first arc-shaped positioning piece 321, the second arc-shaped positioning piece 322, the third arc-shaped positioning piece 323 and the fourth arc-shaped positioning piece 324, when the positioning connector 3 is connected to the mounting seat 23, the first arc-shaped positioning piece 321, the second arc-shaped positioning piece 322, the third arc-shaped positioning piece 323 and the fourth arc-shaped positioning piece 324 are all in contact with the mounting seat 23 on all sides, so that the positioning connector 3 is not easy to shake.

By setting the vertical tube 341 and the inclined tube 342, after the tube body 41 of the funnel 4 is inserted into the inclined tube 342, the funnel 4 is roughly in a horizontal state, so that the nutrient solution is not easy to flow out along the outer wall of the funnel 4.

[0036] Furthermore, it also includes a clamping and fixing mechanism 5, which includes a connecting seat 51, a connecting rod 52, a clamping claw 53, a spring 54, a connecting cap 55 and a pull head 56. The connecting seat 51 is arranged on the side of the mounting seat 23, and a receiving cavity is formed in the connecting seat 51. The connecting rod 52 includes a first rod body 521 and a second rod body 522. The first rod body 521 passes through the mounting seat 23 along the receiving cavity and is connected to the clamping claw 53. A limiting ring 523 is formed between the second rod body 522 and the first rod body 521. The clamping claw 53 is located in the mounting seat 23, and the spring 54 is sleeved on the first rod body 521. On the second rod body 522, one end of the spring 54 abuts against the limiting ring 523, the connecting cap 55 is arranged on the connecting seat 51, the connecting cap 55 abuts against the other end of the spring 54, the connecting cap 55 is provided with a through hole for the end of the second rod body 522 to pass through, and the pull head 56 is connected to the end of the second rod body 522; the clamping and fixing mechanism 5 includes a left clamping and fixing mechanism 5a and a right clamping and fixing mechanism 5b, the clamping claw 53 of the left clamping and fixing mechanism 5a abuts against one side of the connecting hard tube 12, and the clamping claw 53 of the right clamping and fixing mechanism 5b abuts against the other side of the connecting hard tube 12.

[0037] When in use, the cannula 1 is inserted into the esophagus from the patient's mouth, and then the mouth pad 2 is placed on the patient's mouth, the pull head 56 is pulled outward, and then the pull head 56 is released. Under the action of the spring 54, the clamping claw 53 of the left clamping and fixing mechanism 5a abuts against one side of the connecting hard tube 12, and the clamping claw 53 of the right clamping and fixing mechanism 5b abuts against the other side of the connecting hard tube 12, thereby clamping and fixing the cannula 1, and the clamping and fixing process is relatively simple.

[0038] Furthermore, the cannula 1 includes an insertion hose 11 and a connection hard tube 12, and the connection hard tube 12 is fixed on the insertion hose 11. By providing the insertion hose 11, the insertion hose 11 is relatively soft, so that it is easy to insert into the patient's body, and the connection hard tube 12 is relatively hard, so that the connection hard tube 12 is not easy to deform under the action of the clamping claw 53. By providing the connection seat 51, the connection rod 52, the clamping claw 53, the spring 54, the connection cap 55 and the pull head 56, when installing the clamping and fixing mechanism 5, the end of the first rod body 521 passes through the mounting seat 23 from the accommodating cavity and is connected to the clamping claw 53, and then the spring 54 is sleeved on the second rod body 522, and then the connection cap 55 is connected to the connection seat 51 to realize that the spring 54 is restricted in the accommodating cavity, and finally the pull head 56 is connected to the end of the second rod body 522, so that the installation of the clamping and fixing mechanism 5 is completed, and the installation is relatively convenient. When the cannula 1 needs to be clamped, the pull head 56 is pulled, and the spring 54 is compressed under the action of the limit ring 523, so that the clamping jaw 53 moves. After loosening, the clamping jaw 53 abuts against the side of the cannula 1 under the action of the spring 54, thereby clamping the cannula 1.

[0039] In this embodiment, a limiting step 121 is provided at the end of the connecting rigid tube 12. After the clamping jaw 53 of the left clamping and fixing mechanism 5a abuts against one side of the connecting rigid tube 12, and the clamping jaw 53 of the right clamping and fixing mechanism 5b abuts against the other side of the connecting rigid tube 12, the limiting step 121 is located directly above the clamping jaw 53, and the limiting step 121 can abut against the upper side of the clamping jaw 53, thereby further preventing the cannula 1 from moving.

[0040] Furthermore, a through hole is provided on the mounting seat 23 for the first rod 521 to pass through. By providing the through hole, the first rod 521 passes through the through hole during installation, thereby facilitating the connection between the first rod 521 and the clamping jaw 53.

[0041] In this embodiment, an anti-slip layer is provided inside the clamping jaw 53 , and after the clamping jaw 53 contacts the side of the cannula 1 , the friction between the clamping jaw 53 and the cannula 1 is increased, so that the effect of fixing the cannula 1 is better.

[0042] Furthermore, a second external thread is provided on the connection seat 51, and a second internal thread connected to the second external thread is provided in the connection cap 55. When the connection cap 55 is connected to the connection seat 51, the connection cap 55 is rotated so that the second external thread is connected to the second internal thread, making the connection process of the connection cap 55 and the connection seat 51 more convenient.

[0043] In a preferred embodiment of the utility model, a third external thread is provided at the end of the second rod body 522, and a third internal thread connected to the third external thread is provided in the pull head 56. When the pull head 56 is connected to the second rod body 522, the pull head 56 is rotated so that the third external thread is connected to the third internal thread, making the connection process of the pull head 56 and the second rod body 522 more convenient.
