For a more complete and clear disclosure of the present invention, and for its objects and advantages, reference should be made to the following detailed description, taken in conjunction with the accompanying drawings and reference numerals:

please refer to fig. 1-4.

The nasogastric tube comprises a hollow first tube body 1, a clamping piece 2 and a positioning piece 3; wherein:

the front and back ends of the first tube body 1 are provided with openings 11 and 12, the opening 11 at the front end is in a necking shape, so that a lens penetrating through the front end of the nasogastric lens 4 in the first tube body 1 is exposed but does not protrude out of the opening 11, more than one through hole 13 penetrating through the tube wall is formed in the first tube body 1 and adjacent to the front end opening 11, a blocking ring 14 is arranged on the tube wall of the tube body 1 adjacent to the rear end opening 12, a plurality of through holes 141 are formed in the blocking ring 14, and a caulking groove 15 is formed in the tube wall of the first tube body 1 adjacent to the blocking ring 14;

the clamping piece 2 comprises two corresponding positioning sections 21, a beam ring section 22 with a C-shaped section is connected and arranged between the two positioning sections 21, and the beam ring section 22 is correspondingly embedded and clamped at the embedding groove 15 of the first pipe body;

the positioning piece 3 is synchronously sleeved on the two positioning sections 21, so that the two positioning sections 21 are attached to each other as much as possible, and the binding ring section 22 generates a binding fixing force, and the endoscope 4 penetrating through the first tube body 1 is positioned with the first tube body 1 through the binding force, so that the endoscope 4 is prevented from sliding and separating.

In the preferred embodiment of the present invention shown in fig. 1 to 4, the outer surfaces of the two positioning sections 21 are provided with external threads 211, the positioning member 3 is provided with internal threads 31, and the internal threads 31 of the positioning member 3 correspondingly lock the external threads 211 on the two positioning sections 21 to fix the positioning member 3 on the two positioning sections 21.

In the preferred embodiment of the present invention shown in fig. 5 and 6, the positioning member 3 has a fitting hole 32, and the fitting hole 32 is sleeved with two positioning sections 21 to fix the positioning member 3 on the two positioning sections 21.

Please refer to fig. 1-4. When the nasogastric tube is to be sent into the stomach, the first tube body 1 of the nasogastric tube can be sleeved outside the nasogastric tube 4, and the lens at the front end of the nasogastric tube 4 is exposed at the front end opening 11 of the tube body 1, and as the caliber of the opening 11 is smaller than that of the front end of the nasogastric tube 4, the nasogastric tube 4 cannot protrude from the opening 11; then, the collar section 22 of the clamping piece 2 is looped around the caulking groove 15 of the tube body 1, and then the two positioning sections 21 of the clamping piece 2 are fixed by the positioning piece 3, so that the first tube body 1 and the nasogastric tube 4 are fixed together by utilizing the binding positioning of the clamping piece 2 and the positioning piece 3, thus, when the nasogastric tube is placed, medical staff can shoot the returned picture through the lens of the nasogastric tube 4 to monitor the position of the nasogastric tube and further serve as the basis for controlling the advancing direction of the nasogastric tube by the nasogastric tube 4, and smoothly send the nasogastric tube to the stomach. In addition, besides the nasogastric tube of the present invention can enter the stomach through the nasal cavity, the nasogastric tube of the present invention can be covered and fixed outside the mouth like a wearing mask by matching with a limiting mask 7 as shown in fig. 23, and then the nasogastric tube with the nasogastric tube 4 already penetrated inside can be penetrated into the oral cavity by the perforation 71 of the limiting mask 7 and enter the stomach (as shown in fig. 24).

After the nasogastric tube is delivered to the stomach, the positioning piece 3 can be taken down from the positioning section 21 of the clamping piece 2, so that the clamping piece 2 is not tightly clamped with the nasogastric tube and the nasogastric tube 4, and the nasogastric tube 4 can be pulled out at the moment, and only the nasogastric tube is left in a human body for feeding.

Please refer to fig. 7-9.

Referring to fig. 10-13, different aspects of the potting heads 16a, 16b, 16c are shown; wherein, the end cap 16a forms a top surface 16a1 at the front end, and a cross-shaped cutting groove 16a2 is arranged on the top surface 16a1, which can also prevent the nasogastric lens 4 from protruding from the front end opening 11. The end sleeve 16b is connected with the circular tube section 16b2 in the backward direction of the conical section 16b1, and the effect of preventing the nasogastric lens 4 from protruding out of the front end opening 11 is achieved by using the opening caliber of the conical section 16b1 to be smaller than the tube diameter of the nasogastric lens 4. The end cap 16c engages the tubular segment 16c2 rearwardly of the tapered segment 16c1 and forms a top surface 16c3 at a forward end thereof, with a cross cut 16c4 provided in the top surface 16c 3.

Referring to fig. 1 to 3, the pipe diameters of the first pipe 1 from the front end opening 11 to the rear end opening 12 are similar.

Fig. 14 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.

Fig. 15 to 17 show that the pipe diameter of the front section of the first pipe body 1 gradually decreases and increases from the front end opening 11 to the rear in the axial direction, and the pipe body of this section is formed into an arc-shaped concave shape.

Please refer to fig. 18. In a preferred embodiment of the present invention, a bendable flexible section 17 may be further formed at the front section of the first tube body 1.

FIG. 19 shows the flexible section 17 as a bellows body with a saw-tooth cross section; in fig. 20, the flexible section 17 is disclosed as a bellows tube having an arc-shaped cross section.

Fig. 18 illustrates the flexible section 17 as being provided in the case where the first pipe body 1 is the embodiment shown in fig. 1 to 3; fig. 21 shows the flexible section 17 being disposed in the state of the first tube 1 being the embodiment shown in fig. 14; fig. 22 shows the flexible section 17 in the case where the first pipe body 1 is the embodiment shown in fig. 15 to 17.

In the embodiment of the nasogastric tube described in fig. 1 to 22, the nasogastric tube further comprises a second tube body 5 and a coupling member 6, wherein the rear end of the first tube body 1 is a first coupling end 18, the front end of the second tube body 5 is a second coupling end 51, the coupling member 6 is a hollow annular body, the inner wall surface of the coupling member 6 is provided with a coupling portion 61, and the front end and the rear end of the coupling member 6 are fixedly coupled with the first coupling end 18 and the second coupling end 51 by the coupling portion 61.

Through the characteristic that the combining element 6 can be movably combined with or separated from the first pipe body 1 and the second pipe body 5, a patient can combine the first pipe body 1 and the second pipe body 5 with or remove the second pipe body 5 according to actual conditions, for example, when the patient is not feeding, the second pipe body 5 can be dismantled, the situation that the appearance of the patient is caused by different side eyes because the second pipe body 5 is vertically arranged outside the nose is avoided, and the patient can further wear a mask directly after the second pipe body 5 is dismantled, so that the patient cannot be perceived by other people to wear the feeding pipe, and the self-confidence of the patient is improved.
