Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an anal tube that integrates intestinal irrigation, drainage, and gas release. Background Technology

[0002] In proctology, after colorectal or anal surgery, to prevent anastomotic leakage or anal stenosis, it is necessary to regularly dilate the anus to drain its contents, reduce intracolonic pressure, and promote anastomotic healing. Currently, in proctology, to address the high intracolonic pressure after surgery, a decompression drainage tube is usually placed through the anus and fixed to the perianal skin with sutures to prevent it from falling off. Although the drainage tube can continuously reduce pressure, it is prone to blockage, and the pain caused by the drainage tube being fixed to the skin can cause discomfort to the patient, seriously affecting rest and activity.

[0003] In existing drainage tubes, the balloon used to fix the drainage tube is positioned close to the anus in the intestine. During intestinal drainage and gas expulsion, a gap exists between the tip of the drainage tube and the inner wall of the colon or rectum. A large amount of secretions discharged from the colon or rectum enters the gap between the drainage tube and the inner wall of the rectum. The secretions come into direct contact with the anastomosis, which can contaminate the anastomosis site and easily cause complications. In addition, it increases the difficulty of anal care, increases patient suffering and medical expenses.

[0004] Therefore, we propose a combined anal tube device that integrates intestinal irrigation, drainage, and gas release. Utility Model Content

The second drug delivery port is located at the front end of the second rectal tube. The tail end of the second drug delivery channel extends to a position near the tail end of the second rectal tube and is connected to a second drug delivery tube connector via a pipe.

[0013] Furthermore, the front end of the second flushing channel extends to the front end of the second anal canal and is provided with a second flushing port. The second flushing port is opened on the outer wall of the second anal canal and is located on the side of the second balloon near the first anal canal. The tail end of the second flushing channel extends to the tail end of the second anal canal and is connected to a second flushing pipe connector through a pipe. The second flushing pipe connector is provided with a plug.

[0014] Furthermore, the tail end of the second air injection channel extends to the middle of the second anal tube and is connected to the second air injection pipe connector via a pipe.

[0021] This invention consists of two anal tubes, with their ends fitted together. Using balloons, irrigation ports, and medication ports located at the ends of both tubes, and through a staggered fixing method, the drainage of intestinal waste and decompression are isolated above the anastomosis. This creates an independent space within the intestine before and after the anastomosis, preventing secretions and excrement from directly contacting the anastomosis. This effectively avoids contamination of the anastomosis site by secretions or excrement, reducing the probability of complications. It also reduces the difficulty of anal care, alleviates patient suffering, and allows for normal irrigation and medication administration at the anastomosis site without affecting drainage, decompression, or air release, significantly reducing the difficulty of intestinal anastomosis care.

[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0029] Example:

[0030] Existing drainage tubes, due to the limitations of human organ and tissue structure, typically have the balloon used to fix the tube inside the intestine near the anus. This creates a gap between the front end of the drainage tube and the inner wall of the colon or rectum during drainage and gas expulsion. Large amounts of secretions from the colon or rectum can enter this gap and directly contact the anastomosis, making the anastomosis highly susceptible to infection and complications. It also increases the difficulty of anal care and patient discomfort. To address this issue, we designed a system consisting of two anal tubes. The two tubes are fitted together at their front ends and fixed in a staggered manner. Using a balloon, irrigation port, and medication port, the drainage and decompression of intestinal waste are isolated above the anastomosis. An independent space is created within the intestine before and after the anastomosis to prevent secretions and waste from directly contacting the anastomosis, thus avoiding contamination and reducing the probability of complications. This reduces the difficulty of anal care and alleviates patient discomfort. The specific solution is as follows:

[0031] like Figure 1-3As shown, this embodiment provides an anal tube that integrates intestinal irrigation, drainage, and gas expulsion. It includes a transparent anal tube 1 and an anal tube 2. The two anal tubes are designed with transparent tube bodies, which allows medical staff to more intuitively observe the discharge of excrement and secretions in the intestine.

[0032] A drainage bag 3 connected to the tail end of the No. 1 anal tube 1 is used to collect excrement, secretions, and medications drained from the intestine, as well as to flush the intestinal anastomosis site. A No. 1 balloon 10 is located on the outer side of the proximal end 4 of the No. 1 anal tube 1. The tube wall of the No. 1 anal tube 1 is provided with a No. 1 air injection channel 11, a No. 1 flushing channel 16, and a No. 1 drug administration channel 13. The front end of the No. 1 air injection channel 11 is connected to the No. 1 balloon 10. The tail end of the No. 1 air injection channel 11 extends to the middle of the No. 1 anal tube 1 and is connected to a No. 1 air injection connector 12 through a pipe. The front end of the No. 1 flushing channel 16 extends... A first flushing port 17 is provided at the proximal end 4 of the first anal tube 1. The first flushing port 17 is located on the tube wall of the first anal tube 1. The tail end of the first flushing channel 16 extends to the middle of the first anal tube 1 and is connected to the first flushing tube connector 18 through a pipe. The front end of the first drug delivery channel 13 extends to the proximal end 4 of the first anal tube 1 and is provided with a first drug delivery port 15. The first drug delivery port 15 is located on the end face of the proximal end 4 of the first anal tube 1. The tail end of the first drug delivery channel 13 extends to the middle of the first anal tube 1 and is connected to the first drug delivery tube connector 14 through a pipe.

[0033] To ensure effective coordination between rectal tube 1 (No. 1) and rectal tube 2 (No. 2), a branch channel 5 is provided on the side of the middle portion of rectal tube 1. Rectal tube 2 (No. 2) is inserted inside the branch channel 5, with its front end extending from the proximal end 4 of rectal tube 1 beyond its outer side. A balloon 25 is located on the outer side of the front end of rectal tube 2 (No. 2). The inner wall of rectal tube 2 (No. 2) contains a second air injection channel 26, a second drug delivery channel 28, and a second flushing channel 31. The second air injection channel 26... The front end of the second-stage balloon 25 is connected to the second-stage balloon 25. One end of the second-stage drug delivery channel 28 extends to the front end of the second-stage anal tube 2 and is provided with a second-stage drug delivery port 30. The second-stage drug delivery port 30 is located at the end of the front end of the second-stage anal tube 2. The rear end of the second-stage drug delivery channel 28 extends to the rear end of the second-stage anal tube 2 and is connected to a second-stage drug delivery tube connector 29 through a pipe. The front end of the second-stage flushing channel 31 extends to the rear end of the second-stage anal tube 2 and is provided with a second-stage flushing port 34. The second-stage flushing port 34 is located on the outer wall of the second-stage anal tube 2 and is located on the side of the second-stage balloon 25 near the first-stage anal tube 1. The rear end of the second-stage flushing channel 31 extends to the rear end of the second-stage anal tube 2 and is connected to a second-stage flushing tube connector 32 through a pipe. A plug 33 is provided inside the second-stage flushing tube connector 32. The rear end of the second-stage air injection channel 26 extends to the middle of the second-stage anal tube 2 and is connected to a second-stage air injection tube connector 27 through a pipe. The rear end of the second-stage anal tube 2 is connected to a connecting tube 21. A negative pressure drainage device 22 is connected; the negative pressure drainage device 22 has an air inlet and an air outlet at its two ends, respectively. The air inlet of the negative pressure drainage device 22 is detachably connected to the connecting tube 21 by a plug-in type. The negative pressure drainage device 22 is an elastic rubber balloon. A one-way valve is installed on the air inlet and air outlet at both ends of the negative pressure drainage device 22. The function of the one-way valves installed on the air inlet and air outlet of the negative pressure drainage device 22 is to help medical staff to achieve negative pressure exhaust through the negative pressure drainage device 22.

[0034] Among them, the middle wall of the No. 1 anal tube 1 is also provided with a capped connection port 8 for connecting with the connecting tube 21.

[0035] During the entire process, the proximal end 4 of the first anal tube 1 enters the intestine from the patient's anus. The first balloon, along with the first inflation channel 11 and the inflation device connected to the first inflation tube connector 12, fixes the first anal tube 1 in the patient's intestine. Since only the sphincter at the anus can effectively block the balloon, in routine operation, the first balloon 10 is fixed close to the anus. Therefore, the function of the first anal tube 1 is to fix and seal while simultaneously fixing the second anal tube 2, allowing the second anal tube 2 to enter the first anal tube 1 through the branch channel 5, avoiding the anus. This allows the front end of the second anal tube 2 to penetrate deep into the intestine. With the help of the second balloon 25 designed on it, a balloon barrier is established in the intestine above the anastomosis, thus placing the anastomosis within the protective zone formed between the first balloon 10 and the second balloon 25. This prevents intestinal excrement and secretions from contaminating the anastomosis, preventing anastomotic infection and complications, and reducing patient suffering.

[0036] Meanwhile, since both the No. 2 anal tube 2 and the No. 1 anal tube 1 have the functions of flushing, medication administration, and waste removal, when the No. 2 anal tube 2 establishes a barrier in the intestine using the No. 2 balloon 25, it can also irrigate the intestine at the anastomosis site through the No. 2 flushing port 34 without affecting the discharge of excrement and secretions. At the same time, the No. 1 flushing port 17 and the No. 1 medication port 15 on the No. 1 anal tube 1, as well as the No. 2 medication port 30 on the No. 2 anal tube 2, can effectively flush and administer medication to the intestine within the protected area, which helps the anastomosis to recover.

[0037] It should be further explained that the negative pressure drainage device 22 is a single-use device that is placed between the device and the body. The operator squeezes the negative pressure drainage device 22 to expel the air inside through the one-way valve at the air outlet. Then, the operator releases the negative pressure drainage device 22, and the rebound of the material itself generates negative pressure. Medical staff can judge the gas discharge from the intestines by observing the recovery state of the negative pressure drainage device 22. At the same time, the negative pressure generated by the negative pressure drainage device 22 has a certain promoting effect on gas expulsion. When the medical staff observes secretions or excrement flowing out through the second rectal tube 2, the negative pressure drainage device 22 is removed from the end of the connecting tube 21. The end of the connecting tube 21 connected to the negative pressure drainage device 22 is then connected to the sealed connection port 8, so that the tail end of the second rectal tube 2 is reconnected to the first rectal tube 1, so that the drained excrement or secretions can flow into the drainage bag 3.

[0038] The proximal end 4 of the No. 1 anal tube 1 is provided with an infeed mark 20 and a fixing ring 19. The infeed mark 20 is designed to allow doctors to more intuitively judge the depth of the No. 1 anal tube 1 inside the human body when fixing the No. 1 anal tube 1. The fixing ring 19 is designed to fix the entire device with a rope when the patient moves, so as to prevent the No. 1 anal tube 1 from causing discomfort to the patient under the action of gravity through the No. 1 balloon 10.

[0039] A stop valve 7 is installed in the middle of the first anal tube 1, between the capped connection port 8 and the fixing ring 19. A stop valve 23 is installed at the tail end of the second anal tube 2. The first stop valve 7 and the second stop valve 23 include, but are not limited to, any one of pipe clamps and rotary valves. Their main function is to control the opening and closing of the first anal tube 1 and the second anal tube 2.

[0040] An operating hole 9 with a cap is provided on the wall of the first anal tube 1, located between the first stop valve 7 and the fixing ring 19; an operating hole 24 with a cap is provided on the wall of the second anal tube 2, located on the side of the second stop valve 23 away from the connecting pipe 21. The first and second operating holes 9 and 24 with caps are closed when not in use. Their main function is to facilitate medical staff to take samples through the first or second anal tube 1 and to insert the endoscope into the first or second anal tube 2 through the first and second operating holes 9 and 24 with caps.

[0041] like Figure 5 As shown, a pipe clamp 6 is provided on the outside of the branch channel 5. The pipe clamp 6 is composed of two semi-circular rings. One end of the two rings is connected to each other, and the other end of the two rings is integrally formed with mutually cooperating toothed locking buckles 601. After the No. 2 anal tube 2 is inserted into the branch channel 5, the pipe clamp 6 is wrapped around the outside of the branch channel 5 to lock the No. 2 anal tube 2 and the branch channel 5.

[0042] Because the No. 2 rectal tube 2 needs to establish an isolation zone deeper inside the intestine during use, the No. 2 balloon needs to maintain a close fit with the intestinal wall for a long time. In order to avoid the intestinal wall in the same position being compressed for a long time, two No. 2 balloons 25 are set side by side at the front end of the No. 2 rectal tube 2. At the same time, a No. 2 air injection channel 26 is opened on the inner wall of the No. 2 rectal tube 2 corresponding to the two No. 2 balloons 25. The tail ends of the two No. 2 air injection channels 26 are connected to a No. 2 air injection pipe connector 27 through pipes. This allows the two No. 2 balloons 25 to work alternately and independently, thereby avoiding the intestinal wall being compressed in the same position for a long time.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
