The connector 3 is inserted into the connecting sleeve 4 so that the elasticity of the spring piece 62 in the connecting component 6 allows the connecting block 61 to pass through the positioning groove 5 for snap-fitting. The rubber hemisphere 31 in the connector 3 is snapped into the groove 401 in the connecting sleeve 4 so that the iron ring 41 is magnetically attracted to the surface of the magnetic ring 32, thereby further limiting the connection between the connector 3 and the connecting sleeve 4 and improving the stability of the connection.

[0026] like Figure 2As shown, the utility model provides a technical solution for a tumor gastrointestinal nutrition tube connection device: connecting grooves 301 are respectively provided on the left and right sides of the outer wall of the connecting head 3, the interiors of the two connecting grooves 301 are movably connected to the outer walls of the two connecting components 6, a plurality of rubber hemispheres 31 are fixedly connected in a circular array on one side of the top of the outer wall of the connecting head 3 close to the connecting component 6, an arc groove 302 is provided on the bottom of the connecting head 3 close to the outer wall of the nutrition tube 1, a magnetic ring 32 is fixedly connected to the top of the inner wall of the arc groove 302, and a preliminary connection can be made with the connecting sleeve 4 through the connecting component 6, and the rubber hemisphere 31 and the magnetic ring 32 in the arc groove 302 can be further connected to the interior of the connecting sleeve 4 to increase the stability of the connection.

[0027] like Figure 3 As shown, the utility model provides a technical solution for a tumor gastrointestinal nutrition tube connection device: the connection component 6 includes a connection block 61 and a spring 62, the end of the connection block 61 close to the nutrition tube 1 is fixedly connected to the spring 62 in the vertical direction away from the end of the nutrition tube 1, and the other end of the spring 62 is fixedly connected to the inner wall of the connection groove 301 in the vertical direction, the connection block 61 is set to a triangular shape, and the spring 62 is set to a Z shape. By utilizing the elasticity of the spring 62, it is convenient to install and disassemble the nutrition tube 1 and the external esophagus 2, and the tops of the inner walls of the two connection grooves 301 are provided with limiting arc grooves 3010. The tops of the two connection blocks 61 are fixedly connected with sliders 611, and the outer walls of the sliders 611 are slidably connected to the inner walls of the limiting arc grooves 3010. The displacement of the connection block 61 is limited by the slider 611 sliding along the inner wall of the limiting arc groove 3010.

[0028] like Figure 5 As shown, the utility model provides a technical solution for a tumor gastrointestinal nutrition gastric tube connection device: a ring array is provided on one side of the top of the inner wall of the connecting sleeve 4 close to the positioning groove 5, and the grooves 401 of the same number and size as the rubber hemisphere 31 are opened; an iron ring 41 is fixedly connected to one side of the inner wall of the connecting sleeve 4 close to the external esophagus 2; the inner wall of the groove 401 overlaps the outer wall of the rubber hemisphere 31; the top of the iron ring 41 is magnetically connected to the bottom of the magnetic ring 32; the rubber hemisphere 31 is inserted into the inside of the groove 401, and the magnetic ring 32 is magnetically attracted to the surface of the iron ring 41, which further improves the stability of the connection.

[0029] The working principle of this tumor gastrointestinal nutrition gastric tube connection device is described in detail below.

[0030] like Figure 1-5As shown, when the nutrition stomach tube 1 is connected to the external esophagus 2, first, the connector 3 at the connection of the nutrition stomach tube 1 is inserted into the connecting sleeve 4 at the connection of the external esophagus 2. During the insertion process, because the connecting block 61 is triangular in shape, the inclined surfaces of the left and right connecting blocks 61 slide along the inner wall of the connecting sleeve 4, so that the spring piece 62 is forced to move inward to squeeze the spring piece 62, so that the spring piece 62 is deformed and drives the connecting block 61 to move to the inside of the connecting groove 301, so that the connecting head 3 is inserted into the inside of the connecting sleeve 4, and the connecting block 61 and the positioning groove 5 are connected. When in contact, the elasticity of the spring piece 62 is utilized to make the outer wall of the connecting block 61 pass through the positioning groove 5 for buckling, which can effectively prevent the connecting head 3 and the connecting sleeve 4 from loosening or even falling off. After the connecting head 3 is inserted into the connecting sleeve 4, the multiple rubber hemispheres 31 on the outer wall of the connecting head 3 are respectively stuck into the inside of the groove 401 for limiting. At the same time, the outer wall of the iron ring 41 is magnetically fixed to the bottom surface of the magnetic ring 32 through the arc groove 302, which can further prevent the rotation and displacement of the nutrition gastric tube 1 and the external esophagus 2 after connection, thereby improving the connection effect.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
