Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anti-backflow open-and-close anal tube capable of controllable excretion and exhaust. Background Art

[0002] Rectal cancer is a relatively common malignant tumor that tends to occur very close to the anus. Radical surgery for low-lying rectal cancer will most likely involve rectal diversion and creation of a fistula in the abdominal wall.

[0003] The existing defecation methods after rectal cancer diversion are: 1. Normal defecation through the anus. About 3 to 6 months after preventive diversion, most patients can return to normal defecation through the anus. 2. Permanent diversion. After eating, after metabolism and absorption, it can be discharged from the end of the intestine. The end is generally on the abdominal wall, and discharged from the belly to the artificial stoma. Regular maintenance and care are required, which is relatively less suitable than defecation through the anus.

[0004] For patients who need a stoma to assist with defecation, the cleanliness of the stoma is crucial. If the stoma remains dirty for a long time, it will lead to the growth of bacteria and cause secondary infection. Utility Model Content

[0005] The utility model aims to provide a backflow-proof open-and-close anal tube capable of controlling excretion and exhaust, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0028] See also Figure 1 to Figure 6 In the embodiment of the utility model, a controllable excretion and exhaust anti-backflow open and close anal tube comprises a tube body 1, the tube body 1 can be inserted into the patient's body, and also comprises: a flushing cavity 12 and an in-tube sealing component;

[0029] The flushing cavity 12 is disposed in the tube body 1, and a flushing hole 18 is disposed at one end of the flushing cavity 12, the flushing hole 18 is communicated with a defecation cavity 21 formed in the tube body 1, and the other end is communicated with a flushing cavity interface 17 disposed on the tube body 1;

[0030] The in-tube sealing component is arranged in the tube body 1, and the in-tube sealing component is used to seal the tube body 1. After the tube body 1 is sealed, the cleaning liquid can enter the defecation cavity 21 through the flushing hole 18 to clean the defecation cavity 21 at the lower part of the in-tube sealing component. Specifically, a defecation cavity interface 22 is arranged at one end of the defecation cavity 21;

[0031] The in-tube sealing component includes an in-tube defecation control sealed balloon inflation chamber 10 arranged in the tube body 1, one end of the in-tube defecation control sealed balloon inflation chamber 10 is connected to the in-tube defecation control sealed balloon 6, and the other end is connected to the in-tube defecation control sealed balloon inflation interface 15.

[0032] During use, the tube body 1 is inserted into the wound of the patient, and the external pumping device is connected to the inflation interface 15 of the in-tube defecation control sealed balloon. Compressed air can be injected into the in-tube defecation control sealed balloon 6 through the inflation interface 15 of the in-tube defecation control sealed balloon via the inflation cavity 10 of the in-tube defecation control sealed balloon. At this time, the in-tube defecation control sealed balloon 6 will expand, and the defecation cavity 21 in the tube body 1 will be blocked, so as to avoid the defecation cavity 21 being connected to the outside when the patient does not defecate, causing external bacteria to enter the patient's body, thereby preventing the patient from being infected secondaryly. The gas in the in-tube defecation control sealed balloon 6 can also be discharged through the inflation interface 15 of the in-tube defecation control sealed balloon. At this time, the in-tube defecation control sealed balloon 6 will shrink, thereby making the defecation cavity 21 conductive, so that the patient can defecate. Based on the above arrangement, the switching speed between the conductive and blocked states of the defecation cavity 21 is improved, and the defecation cavity 21 being always in the conductive state, causing secondary infection of the patient, is avoided.

[0033] Furthermore, after the patient has a bowel movement, the defecation cavity 21 will be blocked by the in-tube defecation control sealing balloon 6. At this time, the cleaning liquid can be discharged from the flushing cavity interface 17 into the flushing cavity 12 through the external cleaning liquid pumping device. Then the cleaning liquid enters the defecation cavity 21 through the flushing cavity 12 and the flushing hole 18, and can flush the lower end of the defecation cavity 21 and the in-tube defecation control sealing balloon 6, thereby preventing the patient's feces from adhering to the defecation cavity 21 and the in-tube defecation control sealing balloon 6 and causing bacterial growth.

[0034] Through the above arrangement, on the one hand, the blocking and conducting states of the defecation cavity 21 can be freely switched, so that the tube body 1 can help the patient to defecate and pass gas freely when it is retained for a long time. On the other hand, the residual feces adhering to the defecation control sealing balloon 6 in the flushing tube and the lower end of the defecation cavity 21 can be flushed out to avoid the growth of bacteria and reduce the risk of secondary infection of the patient.

[0035] See also Figure 3 The tube body 1 is provided with an intestinal positioning balloon inflation cavity 8, one end of the intestinal positioning balloon inflation cavity 8 is connected to the intestinal positioning balloon 2 provided on the tube body 1, and the other end is connected to the intestinal positioning balloon inflation interface 13 provided outside the tube body 1;

[0036] The tube body 1 is also provided with an abdominal wall external positioning balloon inflation cavity 9, one end of which is connected to an abdominal wall external positioning balloon 4, and the other end is connected to an abdominal wall external positioning balloon inflation interface 14, and the end of the abdominal wall external positioning balloon 4 away from the intestinal positioning balloon 2 is also provided with a boost baffle 5;

[0037] The tube body 1 is provided with a fixing ring 3 , and the fixing ring 3 is located between the intestinal positioning balloon 2 and the abdominal wall external positioning balloon 4 .

[0038] When the tube body 1 is inserted into the wound of the patient, the intestinal positioning balloon 2 is inside the patient's body and the external abdominal wall positioning balloon 4 is outside the patient's body. At this time, compressed gas can be injected into the intestinal positioning balloon 2 and the external abdominal wall positioning balloon 4 through the intestinal positioning balloon inflation interface 13, the intestinal positioning balloon inflation cavity 8, the external abdominal wall positioning balloon inflation interface 14, and the external abdominal wall positioning balloon inflation cavity 9 respectively, thereby expanding the intestinal positioning balloon 2 and the external abdominal wall positioning balloon 4. When expanded, the two act on the inner and outer sides of the patient's abdominal wall 20 to fix the tube body 1.

[0039] It should be noted that one end of the tube body 1 in the patient's body is connected to the patient's diverted rectum 19. At this time, the intestinal positioning balloon 2 is in contact with the diverted rectum 19. When the intestinal positioning balloon 2 expands, it can drive the diverted rectum 19 to deform and connect the two to prevent loosening. Therefore, when the patient defecates, feces can enter the tube body 1 from the diverted rectum 19 and be discharged from the defecation cavity 21.

[0040] It should also be noted that when the external abdominal wall positioning balloon 4 is expanded, the pressurization baffle 5 has the effect of preventing the external abdominal wall positioning balloon 4 from expanding outward.

[0041] Through the above-mentioned arrangement, the intra-intestinal positioning balloon 2 and the extra-abdominal wall positioning balloon 4 are inflated, so as to realize the connection between the diverted rectum 19 and the tube body 1, and the connection between the tube body 1 and the patient's abdominal wall 20, thereby ensuring that the patient's feces can smoothly enter the defecation cavity 21 from the diverted rectum 19 and the stability of the connection between the tube body 1 and the patient's abdominal wall 20.

[0042] See also Figure 4 The tube body 1 is also provided with an intestinal exhaust cavity 11, one end of the intestinal exhaust cavity 11 is provided with an intestinal exhaust control joint 16, and the other end is provided with a breathable sealing head 7.

[0043] Among them, the breathable sealing head 7 can effectively isolate and filter solid matter and moisture, and allow gas to pass through, so that when the patient's rectum 19 is diverted and the pressure in the tube body 1 is too high, the gas can be discharged through the breathable sealing head 7, the intestinal exhaust cavity 11 and the intestinal exhaust control joint 16 to avoid intestinal bloating of the patient.

[0044] It is worth noting that the intestinal positioning balloon inflation interface 13, the external abdominal wall positioning balloon inflation interface 14, the in-tube defecation control sealing balloon inflation interface 15, and the intestinal exhaust control joint 16 are Luer interfaces, which can achieve quick and firm sealing connection, realize the normally closed channel, and can control the opening and closing of the interface. The flushing cavity interface 17 is a Luer interface or a Luer swivel joint, which can achieve quick and firm sealing connection, realize the normally closed channel, and can control the opening and closing of the interface.
