When the nasogastric tube is to be fed into the stomach, the first tube body 1 of the nasogastric tube can be set outside the nasogascopy 4 and the lens at the front end of the nasogastric tube 4 is exposed at the opening 11 at the front end of the tube. The diameter of the opening 11 is smaller than the front end of the nasal gastroscope 4, so the nasal gastroscope 4 cannot protrude from the opening 11; then, the ring segment 22 of the clamp 2 is bundled at the indentation 15 of the tube body 1, and then The two positioning sections 21 of the clamping member 2 are fixed by the positioning member 3, and the first tube 1 and the gastroscope 4 are fixed together by using the binding positioning of the clamping member 2 and the positioning member 3, so that the medical staff When the nasogastric tube is placed, it can be taken through the lens of the nasogascopy 4 to monitor the position of the nasogastric tube and further serve as a basis for controlling the advancing direction of the nasogastric tube with the nasogascopy 4 to smoothly deliver the nasogastric tube to the stomach. .

After the nasogastric tube is delivered to the stomach, the positioning member 3 can be removed from the positioning section 21 of the clamping member 2 so that the clamping member 2 no longer tightly clamps the nasogastric tube and the nasogascopy 4. That is, the nasal gastroscope 4 can be pulled out, and only the nasal gastrointestinal tube is left in the human body for feeding.

Please refer to Figures 7-9. In a preferred embodiment of the present invention, a conical end sleeve 16 may be further provided at the opening 11 corresponding to the front end of the first pipe body 1, and a metal photosensitive layer is provided on the surface of the end sleeve 16. The light machine's irradiation shows the exact position of the end sleeve 16. In addition, the end sleeve 16 can further prevent the gastroscope 4 from protruding from the front opening 11.

Please refer to the tenth to thirteenth figures, in order to reveal the different end sleeves 16a, 16b, 16c; among them, the end sleeve 16a forms a top surface 16a1 at the tip, and a cross cut groove 16a2 is provided on the top surface 16a1. It is also possible to prevent the nasal gastroscope 4 from protruding from the front opening 11. The end sleeve 16b is connected to the circular tube section 16b2 at the tapered section 16b1 toward the rear. The opening diameter of the tapered section 16b1 is smaller than the diameter of the gastroscope 4 to prevent the gastroscope 4 from protruding from the front opening 11. The end sleeve 16c is connected to the circular pipe section 16c2 at the tapered section 16c1 toward the rear, and a top surface 16c3 is formed at the front end, and a cross cut groove 16c4 is provided on the top surface 16c3.

Please refer to the first to third figures again, it is revealed that the pipe diameters of the first pipe body 1 from the front opening 11 to the rear opening 12 are similar.

The fourteenth figure shows that the diameter of the rear section of the first pipe body 1 is larger than the diameter of the front section of the first pipe body 1.

The fifteenth to seventeenth figures show that the diameter of the front section of the first pipe body 1 gradually decreases from the front opening 11 in the axial direction from the front to the back, and then gradually increases, so that the pipe body in this paragraph forms an arc-shaped concave shape. .

See Figure 18. In a preferred embodiment of the present invention, a bendable flexible section 17 may be further formed on the front section of the first pipe body 1.

The nineteenth figure reveals that the flexible section 17 is a serpentine tubular body with a zigzag section; as for the twentieth figure, it reveals that the flexible section 17 is an arcuate tube with a circular arc section.

The eighteenth figure shows that the flexible section 17 is provided when the first pipe body 1 is implemented as shown in the first to third figures; the twenty-first figure shows that the flexible section 17 is provided when The first pipe body 1 is in the state shown in the fourteenth figure; the twenty-second figure shows that the flexible section 17 is provided when the first pipe body 1 is the one shown in the fifteenth to seventeenth figures. Look like.

Wherein, in the embodiment of the nasogastric tube disclosed in FIGS. 1 to 22, the second tube body 5 and the coupling element 6 are further included, so that the rear end of the first tube body 1 is the first coupling end 18, The front end of the second pipe body 5 is a second joint end 51, the joint element 6 is a hollow ring body, and an inner wall surface is provided with a joint portion 61. The front and rear ends of the joint element 6 are connected by the joint portion 61 and the The first joint end 18 and the second joint end 51 are fixed together.

Through the feature that the coupling element 6 can be movably connected to or separated from the first tube body 1 and the second tube body 5, the patient can join or remove the second tube body 1 or 5 according to the actual situation. 5. For example, when not feeding, the second tube body 5 can be removed to prevent the second tube body 5 from being placed outside the nose, which can cause the patient's appearance and appearance to be different from those of others, and the patient can be further removed. Put on a mask directly after lowering the second tube body 5, so that others cannot detect that the patient has a feeding tube, which improves the patient's self-confidence.
