[0041] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0042] Example 1

[0043] An anal canal 10, such as Figure 1As shown, a tube body 100 and an external fixing tube 200 for fixing the tube body 100 by fitting with the perianal skin are provided. The external fixing tube 200 is detachably sleeved on the outer surface of the tube body 100 .

[0044] The external fixing tube 200 is provided with a plurality of fitting wings 210 and a flexible sleeve tube 220. The plurality of fitting wings 210 are respectively fixedly assembled around the ends of the sleeve tube 220. The sleeve tube 220 is provided with a longitudinal opening 250 for allowing the tube body 100 to enter the interior. Figures 2 to 4 shown.

[0045] It should be noted that the utility model can be provided with multiple external fixing tubes 200, such as 2, 3, 4, 5, etc. The specific external fixing tubes 200 are selected according to the actual situation. This embodiment is described by taking two as an example. Figure 1 , Figure 5 The tube bodies 100 in the figure all use double wavy lines to omit the middle part.

[0046] It should also be noted that after the tube body 100 of the anal tube 10 of the present invention is placed in the body, the sleeve tube 220 is unfolded through the longitudinal opening 250 of the sleeve tube 220, and then the tube body 100 is surrounded and the sleeve tube 220 is repositioned, so that the tube body 100 can be sleeved into the sleeve tube 220. Then the fitting wings 210 are attached to the skin around the anus to fix the tube body 100. The sleeve tube 220 of the present invention can be a sleeve tube 220 with a certain degree of deformation elasticity, such as a silicone tube or a rubber tube.

[0047] The external fixing tube 200 is further provided with a locking member 230 for preventing the longitudinal opening 250 from opening. The locking member 230 is assembled on the outer surface of the sleeve tube 220 .

[0048] It should be noted that the function of the locking member 230 of the utility model is to prevent the patient from turning around or moving, etc., which may cause the longitudinal opening 250 to open and dislocate the tube body 100, after the tube body 100 is inserted into the inside of the sleeve tube 220. The locking member 230 can be a buckle or a tape. When it is a buckle, the sub-parts of the buckle are respectively fixed on both sides of the longitudinal opening 250. After the tube body 100 is inserted into the inside of the sleeve tube 220, the sub-parts can be buckled. The sub-parts of this buckle have various forms, and those skilled in the art can choose according to the actual situation. The locking member 230 can also be a tape. After the tube body 100 is inserted into the inside of the sleeve tube 220, the tape can be wrapped around the outer wall of the sleeve tube 220. This embodiment is described as a tape.

[0049] The external fixing tube 200 is further provided with an anti-slip strip 240 for preventing the tube body 100 from shifting. The anti-slip strip 240 is integrally connected to the inner wall surface of the sleeve tube 220 .

[0050] It should be noted that the anti-slip strip 240 of the present invention functions to further improve the stability of the tube body 100 after the tube body 100 is inserted into the sleeve tube 220 .

[0051] The fitting wing 210 of the present invention is a hydrocolloid dressing with air holes.

[0052] It should be noted that, because excrement often seeps out around the anus, the hydrocolloid dressing is skin-friendly and waterproof, thereby preventing excrement from seeping out and improving comfort. The air holes increase the air permeability of the fitting wing 210.

[0053] The tube body 100 of the utility model is provided with an outer sleeve 110 and an inner sleeve 120. One end of the inner sleeve 120 is detachably sealed and assembled inside the outer sleeve 110, and the other end of the inner sleeve 120 is located outside the outer sleeve 110. The outer sleeve 110 is provided with a main pipe 111 and a branch pipe 112. One end of the branch pipe 112 is integrally connected to the side wall of the main pipe 111, and one end of the inner sleeve 120 extends into the interior of the main pipe 111 through the branch pipe 112. The other end of the branch pipe 112 is provided with an internal thread. The outer surface of the middle part of the inner sleeve 120 is externally threaded, and the inner sleeve 120 is detachably sealed and assembled with the internal thread of the branch pipe 112 through the external thread. The cap 130 is detachably assembled at the end of the inner sleeve 120, such as Figure 5 and Figure 6 .

[0054] It should be noted that, because feces are thick, it is very easy to block the anal canal 10 during use. The function of the inner sleeve 120 of the utility model is that when the feces are thick and block the tube, a cleaning liquid can be injected into the end of the inner sleeve 120 to dilute the feces, and the inner sleeve 120 can even be disassembled through the internal thread of the branch tube 112, and then the inner sleeve 120 can be pulled back and forth inside the outer sleeve 110 to dredge the outer sleeve 110. The function of the cap 130 is to seal the inner sleeve 120 during normal use to prevent excrement from leaking.

[0055] The inner sleeve 120 is also provided with a first through hole 121 for the outflow of cleaning liquid, and the first through hole 121 is located on the end side wall; the main pipe 111 is provided with a plurality of second through holes 113 for the entry of intestinal excrement, and the second through holes 113 are located on the end side wall.

[0056] The anal tube 10 can fix the tube body 100 on the perianal skin through the external fixing tube 200, replacing the traditional suture fixation method, solving the pain caused to the patient when the tube is pulled or touched, and solving the problem of blockage caused by sticky feces.

[0057] Example 2

[0058] An intestinal excrement collection device is provided, wherein the anal tube 10 and the anal bag 20 of the embodiment 1 are provided, and the anal bag 20 and the tube body 100 are detachably assembled. Figure 7 .

[0059] The anal bag 20 is provided with a bag body 300 and a carbon adsorption filter membrane 400 that only passes gas and adsorbs odor in the gas. The carbon adsorption filter membrane 400 is sealed and assembled at the edge of the third through hole (not shown in the figure) of the bag body 300. Figure 8 .

[0060] It should be noted that when the intestinal function is restored, a large amount of gas will be produced in the body, and the gas will enter the anal bag 20. Currently, the anal bag 20 needs to be replaced frequently in clinical practice, which will increase the nursing workload. If it is not replaced in time, it will also increase the risk of anastomotic leakage.

[0061] The carbon adsorption filter membrane 400 of the utility model can discharge the gas in the anal bag 20, while retaining the liquid inside the anal bag 20, thereby preventing the bag from swelling, reducing the bag changing frequency and the nursing workload. At the same time, the carbon adsorption filter membrane 400 can also absorb gas impurities to prevent the generation of odor.

[0062] The anal tube 10 of the intestinal excrement collection device can be fixed on the perianal skin by the external fixing tube 200, replacing the traditional suture fixation method, solving the pain caused to the patient when the tube is pulled or touched. At the same time, it can also solve the problem of bag swelling due to exhaust, reducing the frequency of bag changes and nursing workload.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
