DETAILED DESCRIPTION

[0026] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Example

[0027] like Figure 1-Figure 3 As shown, this embodiment proposes a postoperative exhaust tube for anorectal surgery of traditional Chinese medicine, comprising a hollow tube body, wherein the tube body comprises an introduction section 1, an exhaust section 2, and a gas delivery section 9, wherein the surface of one end of the introduction section 1 is in an arc shape for easy insertion into the patient's body to avoid damaging the patient's intestines, the other end of the introduction section 1 is connected to one end of the exhaust section 2, the other end of the exhaust section 2 is connected to one end of the gas delivery section 9 through a quick connection structure 8, the other end of the gas delivery section 9 is connected to a gas collection and processing device to process the accumulated gas discharged by the patient, and an exhaust hole 3 is provided on the exhaust section 2;

[0028] A limiting structure 4 is provided on the exhaust section 2, and two limiting grooves 4.1 are provided on the inner wall of the limiting structure 4 along the length direction of the exhaust section 2. Two limiting blocks 10 are also fixed on the exhaust section 2, and the two limiting blocks 10 extend into the limiting grooves 4.1 one by one. A position locking mechanism for locking the position of the limiting structure 4 is provided on the tube body below the limiting structure 4.

[0029] Based on the above design, the length of the exhaust tube inserted into the patient's body can be limited by the setting of the limiting structure 4, thereby effectively overcoming the defect of the prior art that the exhaust tube is over-inserted and damages the intestinal mucosa of the patient; in addition, since the limiting structure 4 is looped on the exhaust section 2, the limiting structure 4 can be moved along the exhaust section 2 to adjust the length of the exhaust tube inserted into the patient's body, and during the movement, the movement stroke can be limited by the cooperation of the limiting block 10 and the limiting groove 4.1, and then the position of the limiting structure 4 after movement can be locked by the position locking mechanism, thereby achieving the fixation of the relative position of the limiting structure 4 and the exhaust section 2, so that the exhaust tube described in this example can be suitable for the insertion depth of different patients.

[0030] See attached Figure 2 The exhaust section 2 includes an outer tube 2.1, an inner tube 2.2, and a support member 2.3. The inner tube 2.2 is inserted into the outer tube 2.1. The inner wall of the outer tube 2.1 and the outer wall of the inner tube 2.2 are connected by a plurality of support members 2.3. The support members 2.3 divide the gap between the outer tube 2.1 and the inner tube 2.2 into a plurality of cavities 2.4. A gas transmission channel 2.5 connected to the exhaust holes 3 is formed at the center of the inner tube 2.2. The exhaust holes 3 are evenly distributed on the outer tube 2.1 to improve the exhaust effect of the exhaust pipe.

[0031] Preferably, the outer tube 2.1 and the inner tube 2.2 are coaxially arranged, and the support members 2.3 are symmetrically distributed with the axis of the inner tube 2.2 as the center.

[0032] By adopting the above arrangement, the circumferential side of the exhaust pipe can be deformed evenly, thereby avoiding damage to the intestinal mucosa of the patient caused by non-uniform deformation.

[0033] In this embodiment, the size of one end of the limiting structure 4 close to the position locking mechanism is larger than the other end, and the two ends of the limiting structure 4 are connected by an inner arc surface.

[0034] The above arrangement enables the wearer to fit closely with the buttocks of the patient, and effectively improves the comfort during use without affecting the limiting function of the limiting mechanism 4.

[0035] See attached Figure 3 In this example, the position locking mechanism includes a locking nut 5 and an external thread 6. The external thread 6 is arranged on the exhaust pipe 2 below the limiting structure 4, and the locking nut 5 is threadedly connected to the exhaust section 2 having the external thread 6.

[0036] The limiting structure 4 moves up and down along the tube body so as to adjust the length of the exhaust tube inserted into the patient's body, and the relative position of the limiting structure 4 and the tube body can be locked by rotating the locking nut 5, thereby achieving the purpose of locking the position of the limiting structure 4, so that the exhaust tube of this embodiment can be suitable for the insertion depth of different patients.

[0037] from Figure 3 It can also be seen in the figure that a limit ring 7 is provided on the tube body below the external thread 6 , and the limit ring 7 is used to limit the position of the locking nut 5 .

[0038] The set limit ring 7 can limit the downward adjustment stroke of the locking nut 5. At the same time, due to the length of the limit groove 4.1 opened on the limit structure 4, the stroke of the limit structure 4 moving up and down along the tube body will be limited, thereby facilitating the limit adjustment of the length of the exhaust tube inserted into the patient's body through the limit structure 4.

[0039] See attached Figure 4 In this example, the quick connection structure 8 includes a female connector 8.1, a male connector 8.2 and a connecting portion 8.3. The connecting portion 8.3 is fixed on the male connector 8.2, and the male connector 8.2 is connected to the female connector 8.1 through the connecting portion 8.3.

[0040] Through the quick connection structure of the above structure, it is possible to achieve a quick connection between the exhaust section 2 and the gas delivery section 9, and to achieve a quick replacement of the exhaust section 2, thereby improving the convenience of use of the exhaust pipe.

[0041] In this example, the connection part 8.3 is a threaded structure, that is, the connection part 8.3 is threadedly connected to the female connector 8.1, the inner wall of the female connector 8.1 is provided with an internal thread matching the connection part 8.3, and a sealing ring 8.5 matching the end face of the connection part 8.3 is provided in the female connector 8.1.

[0042] With the above structure, the female connector 8.1 and the male connector 8.2 can be quickly connected by threaded fit, and the provision of the sealing ring 8.5 can ensure the quick sealing of the female connector 8.1 and the male connector 8.2 to avoid air leakage. Example

[0043] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the connecting portion 8.3 is a plug-in structure, that is, the connecting portion 8.3 is plugged into the female connector 8.1, three sealing grooves 8.4 are provided on the connecting portion 8.3 from top to bottom, and three sealing rings 8.5 matching the sealing grooves 8.4 are installed on the inner wall of the female connector 8.1.

[0044] By adopting the above structure, the female connector 8.1 and the male connector 8.2 can be quickly connected by plug-in cooperation. After the male connector 8.2 is inserted into the female connector 8.1, the cooperation of the multiple layers of sealing grooves 8.4 and the sealing ring 8.5 distributed up and down can ensure the rapid sealing of the female connector 8.1 and the male connector 8.2 to avoid air leakage.

[0045] In the specific implementation process, the sizes of the three sealing grooves 8.4 can be the same or different, and the sizes of the corresponding sealing rings 8.5 can be the same or different. If they are the same, the production cost can be reduced, and if they are different, the sealing effect can be further improved. The selection can be made according to actual needs.

[0046] During use of this embodiment, the medical staff first estimates the insertion length of the exhaust tube based on experience, and then moves the limiting structure 4 to the desired position. Thereafter, the locking nut 5 in the position locking mechanism cooperates with the external thread 6 to lock the position of the limiting structure 4, thereby limiting the length of the exhaust tube inserted into the patient's body. This not only effectively overcomes the defect in the prior art that the exhaust tube is over-inserted when the patient moves and damages the patient's intestinal mucosa, but also can be adapted to the insertion depth of different patients.
