Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the present invention discloses a gastrointestinal decompression tube, which comprises a gastrointestinal decompression tube body in the prior art, wherein the gastrointestinal decompression tube body is composed of a distal end section 3, a middle section 2 and a proximal end section 1. It should be noted that, after the gastrointestinal decompression tube body is inserted into the intestines and stomach of the patient: the distal segment 3 refers to the segment located from the throat to the gastrointestinal tract of the patient; the middle section 2 refers to the section from the throat to the nasal cavity of the patient; proximal segment 1 refers to the segment from the patient's nasal cavity to the outside of the patient, and for convenience of description in this embodiment distal segment 3, intermediate segment 2, and proximal segment 1 are named for public understanding.

In the prior art, a gastrointestinal decompression tube body is formed by a distal end section 3, a middle section 2 and a proximal end section 1, and the cross sections of the three sections are the same. In the present case, however, the distal end section 3 and the proximal end section 1 have the same cross section, but the cross section of the intermediate section 2 is smaller than the cross section of the distal end section 3. In particular, the cross-sectional diameter of the intermediate section 2 is smaller by 1.5mm than the distal section 3 or the proximal section 1. As shown in fig. 2, the intermediate segment 2 is fixedly connected to the proximal segment 1 by means of adhesion, and the intermediate segment 2 is connected to the distal segment 3 by means of rotation. This embodiment has given one of them specific rotation connection mode: an annular groove 21 is formed in the outer wall of the middle section 2 close to the distal section 3 in the circumferential direction, and then an annular flange is formed in the inner wall of the distal section 3 close to the middle section 2, and the annular flange and the annular groove 21 are in rotating fit, so that the distal section 3 and the middle section 2 are rotatably connected. Other rotational connections are also conceivable in the prior art, such as a connection of the intermediate section 2 to the distal section 3 by means of a rotating collar.

Because the material of processing preparation intestines and stomach decompression pipe generally all adopts medical soft plastic colloid, consequently, the

interlude

2 and 3 rotation of distal end section in this case connect the back, can realize self sealedly and need not to increase and set up the sealing washer. Of course, as shown in fig. 3, the middle section 2 may also be obtained from the proximal section 1 by an integrally formed tensioning process, and is not limited to the embodiment illustrated. As shown in fig. 4, in order to further optimize the present invention, an eccentric ring 4 is further bonded to an end of the proximal section 1 near the middle section 2, a central axis of the eccentric ring 4 is offset from a central axis of the middle section 2, and the middle section 2 is connected to the proximal section 1 in a twisted manner by using the eccentric ring 4, that is, the middle section 2 is twisted with respect to the axis of the proximal section 1. In the present case, the outer diameter of the eccentric ring 4 is preferably the same as the outer diameter of the proximal section 1, so that the influence of the eccentric ring 4 on the throat of the patient can be reduced.

The present invention will be described in detail with reference to the following embodiments: in specific use, the distal section 3 enters the stomach and intestine of a patient, the middle section 2 is positioned from the nasal cavity to the throat of the patient, and the proximal section 1 is positioned at the section from the nasal cavity to the outside of the body of the patient. When the patient feels that intermediate section 2 is causing discomfort to the throat, proximal section 1 can be twisted back and forth by hand, causing proximal section 1 to rotate about its central axis, while proximal section 1 rotates with intermediate section 2 to adapt intermediate section 2 to the throat of the patient. Since the intermediate segment 2 and the distal segment 3 are connected in a rotating manner, the rotation of the intermediate segment 2 does not cause the rotation of the distal segment 3, which is also a necessary technique for implementing the present solution. In actual use, the length of distal section 3 is almost twice the sum of the lengths of intermediate section 2 and proximal section 1. Therefore, if the gastrointestinal decompression tube body in the prior art is directly twisted and rotated: firstly, the Wechang Araya crown body is too long and can not rotate, so that the gastrointestinal decompression tube body is twisted and sealed and cannot be used; secondly, even if the defects can be overcome, the gastrointestinal decompression tube body can rub the nasal cavity, the throat and the intestines and stomach of the patient at the same time, so that the patient can not bear the gastrointestinal decompression tube.

The scheme creatively improves the existing gastrointestinal decompression tube body, firstly, the section diameter of the middle section 2 is reduced, the middle section 2 is prevented from causing serious friction to the throat of a patient, and the middle section 2 is prevented from contacting the throat of the patient to cause discomfort of the patient; meanwhile, the rotation of the middle section 2 is realized by utilizing the proximal section 1, and the problem that the middle section 2 presses the throat of a patient for a long time is well solved. Then, after the eccentric ring 4 is optimally and additionally arranged, the middle section 2 can be more favorably separated from the throat of a patient quickly during rotation, and the discomfort of the patient is further eliminated quickly.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
