Problems solved by technology

However, the No. 18 to No. 24 Foley catheters used in the above-mentioned catheter ostomy are all soft tubes with small diameters, and it is difficult for feces to pass through, which may easily lead to narrowing and obstruction of the catheter lumen. Flush the catheter with saline, causing inconvenience to patients and medical staff

Embodiment 1

[0038] Embodiment 1: as Figure 1 to Figure 5 As shown, an adjustable ileostomy catheter includes a catheter body 1, the catheter body 1 is a flexible tube with openings at the upper and lower ends, with a hardness of about 85A, which can resist bending and will not easily collapse . The opening at the lower end of the tube body is in the shape of an oblique incision, so that it can be easily inserted into the intestinal tract during operation.

[0039] The upper portion of the outer wall of the catheter body 1 is provided with external threads, and is connected with a pressing piece 11 through threads.

[0040] The outer wall of the catheter tube 1 is also covered with a first balloon 12 and a second balloon 13, the first balloon 12 and the second balloon 13 are non-compliant balloons, which are not easy to leak after filling .

[0041] The first balloon 12 is sleeved on the outer wall of the lower end of the catheter tube body 1, the lower end of the first balloon 12 is c...

Embodiment 2

[0045] Embodiment 2: as figure 2 , image 3 , Figure 4 , Figure 5 As shown, on the basis of Example 1, in order to solve the problem of dredging the obstruction of the tube body, a flushing tube 3 can be set in the tube of the catheter tube 1, the lower end of the flushing tube 3 is closed, and a section of the side wall at the lower end There are a plurality of water outlet holes 31 leading into the conduit body 1 . A third injection port 32 is provided on the upper section of the catheter tube body 1, and the third injection port 32 is connected with the flushing pipe 3 to inject or draw water therefrom.

[0046] Such as Figure 2 to Figure 5 As shown, the shape of the flushing pipe 3 is linear, in fact, the flushing pipe 3 can also be set to other shapes, such as Figure 6 As shown, the flushing pipe 3 is spiral, and this arrangement is better than a straight line, because of the spiral design, the water outlet holes in the lower section can be arranged in a circula...

Embodiment 3

[0050] Embodiment 3: In Embodiment 2, a flushing tube 3 is arranged inside the catheter body 1 , and then water is injected into the flushing tube 3 from the third injection port 32 to dredge the obstruction.

[0051] This embodiment provides another structure to realize the function of unblocking the obstruction, and the technical solution is as follows:

[0052] Such as Figure 8 to Figure 13 As shown, on the basis of Embodiment 1, the upper opening of the catheter body 1 is closed with a silicone plug or connected with a control valve 7 .

[0053] A dredge can also be detachably connected to the upper opening of the catheter body 1 , and the dredge includes a handle 51 , a connecting portion 52 , a helical blade 53 and a connecting pipe 54 connected to the catheter body 1 . The connecting portion 52 and the connecting pipe 54 are engaged with each other.

[0054] The inner wall of the connecting pipe 54 is provided with a snap-in protrusion 541, and the connecting portion...

Abstract

The invention discloses an ileum colostomy catheter. The ileum colostomy catheter comprises a catheter body and is characterized in that a flushing tube is arranged in the catheter body. The ileum colostomy catheter can better achieve obstruction dredging.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an ileostomy catheter capable of blocking intestinal cavity and preventing anastomotic leakage. Background technique [0002] Colorectal cancer is one of the most common malignant tumors of the digestive tract, with the characteristics of high morbidity and high mortality. Surgical resection is currently the most effective treatment for colorectal cancer. For a long time, anastomotic leakage after transabdominal anterior resection of rectal cancer (Dxion) for low rectal cancer (the lower edge of the tumor is <7cm from the anus) has been one of the most serious and common postoperative complications, with an incidence rate of 10% ~20%. Although the traditional colostomy or terminal ileostomy has the effect of preventing and treating anastomotic leakage, the late stoma restoration often causes patients to bear more financial, physical and mental burdens and...
