Embodiment Construction

[0013] like figure 1 As shown, the separable nasogastric tube of the present invention includes gastric tube 1 and intestinal tube 2, such as figure 2 , Figure 2a As shown, the outer wall of the gastric tube 1 is provided with an arc-shaped groove 11 extending along the length direction for accommodating the intestinal tube 2, and a plurality of balloons 3 are sequentially arranged on the gastric tube 1 along the length direction, and the balloons 3 are made of elastic materials. The balloon 3 is set on the gastric tube 1, and the balloon 3 is welded or bonded to the outer wall of the gastric tube 1 except for the part corresponding to the arc groove 11. The welded or bonded part forms a sealing layer 5, and the balloon 3 and the outer wall of the arc-shaped groove 11 form an expansion cavity 31, and the side wall of the gastric tube 1 is provided with an inflatable cavity 4 extending along the length direction. In addition, the sealing layer 5 is provided with a plurality...
