the tail end of the second elastic tube (8) is fixedly connected with a cambered surface lug (9), the diameter of the second elastic tube (8) is smaller than that of the first elastic tube (6), and the hardness of the telescopic tube (7) is greater than that of the first elastic tube (6) and the second elastic tube (8);
a driven gear (11) fixedly arranged at one end of the first rotating shaft (4),
the device comprises a device plate (1), a driving motor, a driven gear (11) and an intermittent air supply assembly, wherein the incomplete gear (10) is rotationally connected to the device plate (1), the driving motor connected with the incomplete gear (10) is fixedly arranged on the device plate (1), the incomplete gear (10) is meshed with the driven gear (11), and the incomplete gear (10) is connected with the slender pipe (3) through the intermittent air supply assembly;
a guide pipe (5) fixedly connected to the device plate (1),
wherein a pushing tube assembly connected with a driven gear (11) is arranged in the guide tube (5), and a clamping assembly is arranged in the guide tube (5);
the intermittent air supply assembly comprises an arc-shaped plate (12) fixedly connected to the device plate (1), an arc-shaped air bag (25) is fixedly connected to the arc-shaped plate (12), a cam (13) matched with the arc-shaped air bag (25) is fixedly connected to the incomplete gear (10), and the arc-shaped air bag (25) is rotationally connected and communicated with the input end of the slender pipe (3) through a connecting pipe (14);
the push tube assembly comprises two conveying wheels (23) which are rotatably connected to the inner wall of the guide tube (5) through respective second rotating shafts (22), and the driven gear (11) is connected with one of the second rotating shafts (22) through a belt transmission (24);
the clamping assembly comprises an annular air bag (17) fixedly connected to the inner wall of the guide pipe (5), an annular plate (16) is fixedly connected to the outer wall of the guide pipe (5), an elastic air bag (18) is fixedly connected to the side wall of the annular plate (16), the elastic air bag (18) is communicated with the annular air bag (17) through a communicating pipe (19), a threaded pipe (15) is connected to the outer wall of the guide pipe (5) in a threaded manner, and one end of the threaded pipe (15) abuts against the telescopic end of the elastic air bag (18);
when the incomplete gear (10) rotates, the arc-shaped air bag (25) is indirectly extruded through the cam (13), namely when the arc-shaped air bag (25) is extruded, namely when the slender tube (3) stops conveying into the stomach tube nutrition tube, the arc-shaped air bag 25 conveys internal gas into the slender tube (3) through the connecting tube (14) and then conveys the internal gas into the first elastic tube (6), the second elastic tube (8) and the telescopic tube (7) from the slender tube (3);
when the cam (13) passes over the arc-shaped air bag (25), the first elastic tube (6), the second elastic tube (8) and the telescopic tube (7) can elastically reset, and then the incomplete gear (10) drives the driven gear (11) to rotate again, so that the slender tube (3) moves for a certain distance in the stomach tube nutrition tube again, and the slender tube moves back and forth in sequence.
2. Gastric tube feeding tube flushing extrusion apparatus as claimed in claim 1 characterized in that the first elastic tube (6), the telescopic tube (7) and the second elastic tube (8) are sleeved with hollow tubes (21), the hollow tubes (21) being fixedly connected between the cambered surface convex blocks (9) and the elongated tube (3).
3. Gastric tube feeding tube flushing extrusion apparatus as claimed in claim 1 characterized in that two of the second shafts (22) are connected by two spur gears of the same diameter in mesh
4. Gastric tube feeding tube flushing extrusion apparatus as claimed in claim 1 characterized in that the outer walls of the first elastic tube (6) and the second elastic tube (8) are provided with evenly distributed anti-slip bumps (20).
5. Gastric tube feeding tube flushing extrusion apparatus as claimed in claim 4 characterized in that the diameter of the first elastic tube (6) and the diameter of the telescopic tube (7) are both smaller than the diameter of the elongated tube (3).
6. Gastric tube feeding tube flushing extrusion apparatus as claimed in claim 1 characterized in that the length of the annular balloon (17) is more than two cm.
7. Gastric tube feeding tube flushing extrusion apparatus as claimed in claim 1 characterized in that the outer wall of the threaded tube (15) is provided with anti-slip threads.
