Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an enterostomy drainage device. Background Art

[0002] The small intestine is an important digestive organ in the human body, and it also has the functions of absorbing nutrients and secreting intestinal fluid. After surgery is performed when the small intestine is diseased, due to the special structure, a fistula is needed to protect the wound and prevent wound infection. Fistula surgery is a common surgery in general surgery. Small intestine fistula is to introduce a drainage tube at the upper end of the wound to drain intestinal fluid and other contents out of the patient's body to avoid intestinal fluid and other contents from contacting the surgical wound, and prevent wound contamination and inflammation. The position of the drainage tube used in the prior art is not easy to adjust after it is fixed in the intestinal cavity. The fixed part of the drainage tube applies pressure on the intestinal wall for a long time, which will cause intestinal wall ischemia, thereby affecting the healing of the surgical wound, greatly reducing the effect of the operation, prolonging the patient's recovery time, and increasing the patient's pain. Therefore, a small intestine fistula drainage device with a fixed position and adjustable fixed pressure is needed. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is clearly and completely described below in conjunction with specific embodiments.

[0023] like Figures 1 to 3 A small intestinal fistula drainage device is shown, which includes a mushroom head 1, a drainage tube 2, a first water bag 3 and a second water bag 4. The mushroom head 1 is arranged at the end of the drainage tube 2, and a plurality of drainage holes 11 are distributed on its surface and are connected to the inner cavity of the drainage tube 2 for draining the intestinal fluid in the small intestine to the outside of the patient. The first water bag 3 and the second water bag 4 are arranged on one side of the mushroom head 1. The first water bag 3 and the second water bag 4 are fixedly sleeved on the drainage tube 2 at a certain distance from each other. The first water bag 3 is connected to the first water injection port 5, and the second water bag 4 is connected to the second water injection port 6. The first water injection port 5 and the second water injection port 6 are fixedly arranged on the drainage tube 2. The mushroom head 1, the drainage tube 2, the first water bag 3 and the second water bag 4 are integrally formed, and are preferably made of silicone, rubber or polyvinyl chloride.

[0024] The outer diameter of the first water bag 3 and the second water bag 4 after water injection is set at 10~60mm. Due to the different manufacturing materials, the expansion degrees of the first water bag 3 and the second water bag 4 are different. The initial outer diameter is adjusted with the different materials. Selecting an appropriate outer diameter is conducive to close fit with the small intestine wall without increasing the burden on the intestinal wall. The distance between the first water bag 3 and the mushroom head 1 is 20~30mm, and the distance between the first water bag 3 and the second water bag 4 is 60~80mm. The appropriate distance can reduce the burden on the intestinal wall and avoid intestinal ischemia. Alternating the first water bag 3 and the second water bag 4 is conducive to the recovery of the intestinal wall, and at the same time avoid the distance between the mushroom head 1, the first water bag 3 and the second water bag 4 being too long to increase the difficulty of the insertion operation.

[0025] like Figure 2 As shown, the first water bag 3 is connected with the first water injection port 5 through the first channel 7, and the second water bag 4 is connected with the second water injection port 6 through the second channel 8. The first channel 7 and the second channel 8 are fixedly arranged in the wall of the drainage tube 2. Preferably, the first channel 7 and the second channel 8 are integrally formed with the drainage tube 2 and arranged in the wall of the drainage tube 2. The first water injection port 5 and the second water injection port 6 are symmetrically arranged on the drainage tube 2 and obliquely intersect with the drainage tube 2. Preferably, the first water bag 3, the first channel 7, the second water bag 4, the second channel 8, the first water injection port 5, the second water injection port 6 and the drainage tube 2 are integrally formed; the first water injection port 5 and the second water injection port 6 are both provided with a switch valve 9, which facilitates alternately injecting water into the first water bag 3 and the second water bag 4 and maintaining the pressure in the first water bag 3 and the second water bag 4 after injecting water, so that they continue to fit the intestinal wall.

[0026] like Figure 3In the illustrated embodiment 2, a viewing mirror 10 may be provided on the mushroom head 1, and the viewing mirror 10 is connected to the outside through the inner cavity of the drainage tube 2. The blood flow of the intestinal wall can be observed through the viewing mirror 10, and the first water bag 3 or the second water bag 4 that is pressurized and fixed in the intestinal wall can be adjusted and replaced in real time, and the water pressure in the first water bag 3 or the second water bag 4 can be adjusted to restore the intestinal wall to its original state.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
