In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

Referring to fig. 1 to 2, the anti-reflux tube feeding connector of the embodiment of the present invention includes a tapered tube body 10, and a small diameter section of the tube body 10 can be directly inserted into the flaccid tube. Because the tube body 10 is conical, the insertion depth of the tube body 10 can be adjusted to adapt to stomach tubes with different tube diameters or flaccidity tubes, so that the utility model can be widely matched with the existing flaccidity tubes. Preferably, in order to increase the static friction between the tube body 10 and the fistulation tube, a plurality of annular protrusions 40 are provided on the outer side of the tube body 10, the annular protrusions 40 are parallel to each other, and the annular protrusions 40 are spaced along the axial direction of the tube body 10, so that the tube body 10 is prevented from falling out of the fistulation tube, and the tube feeding fluid is further prevented from flowing out of the gap between the tube body 10 and the fistulation tube.

The tube body 10 is provided with a one-way valve structure, and the one-way valve structure can accommodate the fluid flowing from the large diameter end of the tube body 10 to the small diameter end of the tube body 10. The one-way valve structure is similar to the structure of a human heart valve. Optionally, the one-way valve structure includes two symmetrically arranged valves 20, one side of the valve 20 is fixed on the inner side of the tube body 10 to form a fixed edge, and the fixed edges of the two valves 20 are connected to form a closed loop, that is, the fixed edges of the two valves 20 are connected to form a closed ring; the other side of the valve 20 extends to the small diameter end of the tube 10 and forms a free edge, and the free edges of the two pieces of valve 20 are abutted against each other. When the feeder is inserted into the large diameter end of the tube 10 and injected therein, the feeding fluid flows through the tube 10 and pushes apart the two valves 20, thereby flowing into the fistula. When the feeding fluid flows back in the fistulization tube, the fluid pushes the two valves 20 to the large-diameter end of the tube body 10, because the two ends of the fixed edges of the two valves 20 are connected, and the free edges of the two valves 20 are tightly abutted to each other at the moment, the valves 20 are closed, the feeding fluid cannot reversely flow through the one-way valve structure in the tube body 10, and the effect of backflow resistance is achieved. The one-way valve structure is located at the small diameter end of the tube body 10, so that the backflow fluid is prevented from polluting the inside of the tube body 10.

The large diameter end of the pipe body 10 is provided with a cover body which can be opened and closed. The lid includes first sealed lid 31, and the one end of first sealed lid 31 articulates on body 10, is equipped with the first end cap 310 that is used for blockking up body 10 major diameter end on the terminal surface of first sealed lid 31, the inner wall interference fit of first end cap 310 and body 10. The first plug 310 is an elastic member, such as rubber, and when tube feeding is needed, the first sealing cover 31 is opened; after the tube feeding is finished, the first plug 310 is plugged into the large-diameter end of the tube body 10 again, so that the communication between the fistulation tube and the outside can be closed, and gastrointestinal fluids are prevented from seeping out through the fistulation tube and the tube body 10. Preferably, the cover body further comprises a second sealing cover 32, a cover through hole is formed in the first sealing cover 31, a flow hole is formed in the first plug 310, the cover through hole and the flow hole are communicated to form a flow passage, and the second sealing cover 32 is used for sealing the flow passage. The inner diameter of the flow passage is smaller than that of the large-diameter end of the tube body 10, so that the flow passage can adapt to the injector or the feeding device with smaller nipple, and more injectors or feeding devices can be matched with the utility model for use. When a fluid such as a medicine is injected using a syringe, the second sealing cap 32 is opened and the nipple of the syringe is inserted into the flow passage. Specifically, one end of the second sealing cover 32 is hinged to the first sealing cover 31, a second plug 320 is arranged on the end face of the second sealing cover 32, and the second plug 320 is in interference fit with the inner wall of the flow passage. When injection is not required using the syringe, the second sealing cap 32 is closed to prevent leakage of gastrointestinal fluid or fluid left in the tube body 10. The large diameter end of the middle tube 10 and the flow channel on the first sealing cover 31 of the utility model can be connected with a gravity drip device besides the injector or the feeding and irrigating device.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
