[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Figure 1 and Figure 2 All of them are schematic diagrams of the overall structure of the utility model. As shown in the figure, the digestive drainage tube includes an insertion tube 1, a connecting hard tube 2 and a first external lead tube 3 which are connected in sequence. A flushing tube 4 is also connected to the connecting hard tube 2. A threaded mounting head 5 is installed at the water inlet end of the flushing tube 4. The flushing liquid added from the threaded mounting head 5 also enters from the insertion tube 1 to clean the inner wall of the intestine, etc. The insertion tube 1, the first external lead tube 3 and the flushing tube 4 are all soft tubes;

[0032] The outer collecting cylinder 9 is connected to the discharge end of the first outer lead pipe 3, and the inner collecting cylinder 10 is detachably connected to the outer collecting cylinder 9. The inner collecting cylinder 10 is provided with a through groove 103 in the axial direction. A filter screen 11 is fixed inside the through groove 103. The filter screen 11 divides the through groove 103 into a collecting cavity 1031 and a screw connection 1032. The screw connection 1032 is connected to the second outer lead pipe 17. The first outer lead pipe 3 is shorter than the second outer lead pipe 17. During the drainage operation, the in vivo mixture flowing out of the first outer lead pipe 3 can be advanced into the collecting cavity 1031 and the screw connection 1032. The solid part enters the through groove 103, and is blocked by the filter screen 11 and retained in the collecting chamber 1031. The liquid part is discharged through the filter screen 11 and then discharged outside through the second external lead tube 17. The collecting chamber 1031 is used to collect solid drainage materials, which can prevent the solid drainage materials from adhering to the inner wall of the second external lead tube 17, and can also prevent the solid drainage materials from clogging one or more places of the entire longer second external lead tube 17. Medical staff and patients only need to remove the inner collecting tube 10 regularly and pour out the solid drainage materials in the collecting chamber 1031.

[0033] Further references include Figure 4-Figure 5 As shown, the inner collecting cylinder 10 includes a threaded cylinder portion 101 and a screwing portion 102, and the threaded cylinder portion 101 and the screwing portion 102 are integrally formed. The inner wall of the outer collecting cylinder 9 is set as a threaded groove 14, and the threaded cylinder portion 101 is screwed together and connected to the threaded groove 14. The screwed-connected inner collecting cylinder 10 and outer collecting cylinder 9 facilitate quick assembly and separation of the two.

[0034] Through the above technical solution:

[0035] During specific use, the insertion tube 1 is inserted into the area to be drained in the body (stomach or intestines, etc.), and then drainage can be performed. The drainage material enters the connecting hard tube 2 from the insertion tube 1, and then enters the external collecting tube 9 through the first external tube 3 for solid-liquid separation, and then the liquid drainage material is directly discharged from the second external tube 17.

[0036] In addition, see Figure 1 and Figure 3 As shown, the digestive drainage tube also includes a circular plate 6, which is fixed to the outside of the insertion tube 1. A disinfection gasket 12 is adhered to the side of the circular plate 6 facing away from the connecting hard tube 2, and at least two straps 8 are provided on the outer circumference of the circular plate 6. A movable structure is provided between the straps 8 and the circular plate 6, and the straps 8 can move along the outer circumference of the circular plate 6 through the movable structure.

[0037] As mentioned above, after the insertion tube 1 is inserted into the area to be drained, the circular patch 6 can be attached to the patient's skin to increase the contact area, thereby reducing the squeezing force and improving comfort. The use of the sterilized gasket 12 to contact the patient's skin can increase safety, and the use of the strap 8 to wrap around the patient's body can effectively limit the circular patch 6, thereby ensuring the stability of the drainage tube insertion. There is no need to use tape to stick it on the patient's skin, avoiding damage to the skin caused by tearing the tape.

[0038] In the specific implementation of the present utility model, refer to Figure 3 and Figure 5 As shown, the mobile structure includes:

[0039] A groove 7 is provided on the outer circumference of the circular plate 6;

[0040] Two annular chutes 13, the two annular chutes 13 are symmetrically arranged on both sides of the inner side of the groove 7;

[0041] The movable rod 15 has an end portion slidably connected to the annular sliding groove 13 .

[0042] The outer portion of the movable rod 15 is sleeved on the ring 16 , and the end of the binding belt 8 is fixed to the ring 16 .

[0043] Through the above, by utilizing the movable rod 15 to slide in the annular slide groove 13 provided on the inner wall of the groove 7, the position of the strap 8 can be freely adjusted, which is convenient for changing the position of the strap 8 to bypass the patient's body for binding, and is more flexible.

[0044] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
