Description

Technical Field

[0001] The utility model relates to the technical field of anal canals, in particular to an anal canal. Background Art

[0002] Clinically, patients with infectious diarrhea have more frequent bowel movements, and feces can irritate the skin around the anus, causing itching and discomfort, and even complications of incontinence dermatitis such as skin ulceration and infection. This invisibly increases the patient's pain, medical costs, and labor costs. Therefore, patients with more severe diarrhea are usually treated with an anal tube to drain feces, thereby protecting the skin around the anus from continuous irritation from feces.

[0003] In actual use, the anal tube is difficult to fix on the patient's buttocks. First, the loose stools of diarrhea patients will seep out through the anal canal and the gap between the patient's anus. Second, the perianal skin of patients with infectious diarrhea is smeared with corresponding drugs due to eczema, incontinence dermatitis, protective medication and other problems. As a result, the skin surface is not conducive to external fixation with adhesive tape due to ointments or powders, and the anal tube is prone to slippage. If the anal tube slips, the patient will experience the painful process of repeatedly retaining the anal tube. At the same time, the loose stools that seep out make it difficult for the already fragile perianal skin to recover. For nursing staff, repeatedly changing the adhesive tape that has lost its stickiness causes repetitive work.

[0004] Therefore, in order to solve the above problems, the present invention proposes an anal canal which can prevent the anal canal from prolapsing from the patient's anus and can also prevent the leakage of loose stools. Utility Model Content

DETAILED DESCRIPTION

[0024] The following description is intended to fully illustrate the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0025] See also Figure 1-3The present invention provides a technical solution: an anal tube, comprising a tube body 100, wherein the two ends of the tube body 100 in the length direction are respectively an insertion end 101 and an exposed end 102, the inner wall of the tube body 100 forms a lumen 103, an insertion inlet 1011 is formed on one side of the tube body 100 close to the insertion end 101, and an exposed opening 1021 is formed on one side of the tube body 100 close to the exposed end 102, and both the insertion inlet 1011 and the exposed opening 1021 are in communication with the lumen 103;

[0026] The expansion member 200 is connected to the tube body 100 and is located on a side of the insertion port 1011 close to the exposure port 1021. The expansion member 200 has at least two working states, namely a dry state and a liquid absorption state. When the expansion member 200 is in the dry state, a side of the expansion member 200 facing away from the tube body 100 is nearly flush with the outer wall of the tube body 100. When the expansion member 200 is in the liquid absorption state, the side of the expansion member 200 facing away from the tube body 100 extends radially outward from the tube body 100.

[0027] By adding an expansion piece 200 to the tube main body 100, the side of the expansion piece 200 in the dry state facing away from the tube main body 100 is almost flush with the outer wall of the tube main body 100. When the insertion end 101 on the tube main body 100 is inserted into the patient's body, the expansion piece 200 in the dry state can enter the patient's body along with the tube main body 100, wherein the insertion end 101 corresponds to the position of the patient's rectal wall, and the expansion piece 200 corresponds to the position of the patient's anus. During use, the expansion piece 200 can absorb part of the water in the loose stool and then convert it into a liquid absorption state. The expansion piece 200 in the liquid absorption state extends radially outward along the tube main body 100. The expansion piece 200 in the liquid absorption state prevents the tube main body 100 from falling out of the anus. At the same time, the liquid absorption of the expansion piece 200 can prevent the leakage of loose stool.

[0028] In one embodiment of the present invention, the length of the expansion member 200 is 3.5 cm, and the distance between the insertion end 101 and the expansion member 200 is 4 cm.

[0029] See also Figure 2 Regarding the expansion piece 200 in a dry state, in one embodiment of the present invention, in the radial direction of the pipe body 100, the distance between the side of the expansion piece 200 away from the pipe body 100 and the outer wall of the pipe body 100 in the dry state is in a range of 0.5 cm to 1 cm. Preferably, in the dry state, the distance between the side of the expansion piece 200 away from the pipe body 100 and the outer wall of the pipe body 100 is 0.5 cm.

[0030] In another embodiment of the present invention, in a dry state, the side of the expansion member 200 facing away from the pipe body 100 is flush with the outer wall of the pipe body 100. Specifically, a mounting groove is provided on the outer wall of the pipe body 100, and the expansion member 200 is embedded in the mounting groove.

[0031] Furthermore, the distance between the radially outer side surface of the expansion member 200 and the outer wall of the tube body 100 gradually decreases as it approaches the insertion end 101 and the exposed end 102. By limiting the size of the expansion member 200, the expansion member 200 is prevented from scratching the patient's anal sphincter when entering and exiting the patient's rectal cavity from the radially outer side of the tube body 100.

[0032] See also Figure 3 Regarding the expansion member 200 in the liquid absorption state, optionally, in the radial direction of the tube main body 100, the distance between the side of the expansion member 200 facing away from the tube main body 100 and the outer wall of the tube main body 100 in the liquid absorption state is in the range of 3 cm to 4 cm. By limiting the expansion size of the expansion member 200 in the radial direction of the tube main body 100, it is ensured that the expansion member 200 in the liquid absorption state can block the patient's anus and prevent the leakage of loose stools, while preventing the expansion member 200 from compressing the patient's anal sphincter and causing abnormal anal sphincter function. Among them, the expansion member 200 in the liquid absorption state is an elastic expansion member 200, which further prevents the expansion member 200 from squeezing the patient's anal sphincter.

[0033] In order to ensure that the expansion member 200 can absorb and block the possible leakage of loose stools in multiple directions, the expansion member 200 is further arranged along the circumference of the tube body 100. Furthermore, there are multiple expansion members 200, and the expansion members 200 are arranged in sequence along the circumference of the tube body 100. The side of any expansion member 200 along the circumference of the tube body 100 abuts against the side of the adjacent expansion member 200 along the circumference of the tube body 100. By limiting the position of the expansion member 200 along the circumference of the tube body 100, when loose stools flow along the length of the tube body 100, the expansion member 200 can contact the loose stools at any place.

[0034] In one embodiment of the present invention, the expansion member 200 is a tampon, and the tube body 100 is made of silicone. Tampons are characterized by high absorbency, sanitation, comfort, and readily available raw materials. Tampons expand upon absorbing water, thereby preventing them from easily falling out of the anal canal. Tampons expand upon absorbing water, thereby resolving the problem of loose stools leaking into the gap between the anal canal and the patient's anus.

[0035] See also Figure 2 and 3Regarding the connection between the expansion piece 200 and the tube body 100, the tube body 100 and the expansion piece 200 are fixedly connected. Optionally, the tube body 100 and the expansion piece 200 are fixed by bonding or snapping. To prevent the loose expansion piece 200 from shifting and to shape the expansion piece 200 in the liquid-absorbing state, the anal tube further includes an elastic mesh piece 300, which wraps the expansion piece 200 and is fixedly connected to the tube body 100. Furthermore, a connecting groove 104 is provided on the outer wall of the tube body 100, and the elastic mesh piece 300 is interference-fitted into the connecting groove 104. The elastic mesh piece 300, the expansion piece 200, and the connecting groove 104 correspond one to one. Through the above definition, the elastic grid member 300 can cooperate with the connecting groove 104 to penetrate deep between the inner wall and the outer wall of the pipe body 100, ensuring that its position on the pipe body 100 is fixed. The expansion member 200 in the dry state is compressed and tightly adhered to the outer wall of the pipe body 100 under the action of the elastic grid member 300. In the liquid absorption state, the expansion member 200 expands and stretches the elastic grid member 300, but because the elastic grid member 300 is connected to the connecting groove 104, it is still connected to the outer wall of the pipe body 100.

[0036] In one embodiment of the present invention, the elastic mesh member 300 is a sterile non-woven fabric, which is not easily hydrolyzed.

[0037] Regarding the specific structure of the connecting groove 104, the connecting groove 104 includes a first groove portion 1041 and a second groove portion 1042. The first groove portion 1041 is arranged along the radial direction of the pipe body 100, and the second groove portion 1042 is arranged along the circumferential direction of the pipe body 100. One end of the first groove portion 1041 corresponds to the center position of the expansion member 200 in the circumferential direction of the pipe body 100, and the other end of the first groove portion 1041 is connected to the center position of the second groove portion 1042 in the circumferential direction of the pipe body 100. The first groove portion 1041 and the second groove portion 1042 are both located between the inner wall and the outer wall of the pipe body 100. By adding the connecting groove 104, the connecting groove 104 and the elastic mesh member 300 form a structure similar to an "I" shape, which ensures the stable connection between the pipe body 100, the expansion member 200, and the elastic mesh member 300, and ensures that the relative position of the expansion member 200 remains unchanged.

[0038] In one embodiment of the present invention, the number of the expansion members 200 and the number of the connecting grooves 104 are both 4, and adjacent expansion members 200 are arranged at equal intervals along the circumference of the tube body 100. Correspondingly, adjacent connecting grooves 104 are arranged at equal intervals along the circumference of the tank body, and the angle between the opening directions of adjacent connecting grooves 104 is 90°.

[0039] In addition, the anal tube has the following improvements: existing disposable silicone anal tubes in clinical practice do not have built-in fixing devices. Nurses need to use rubber bands or pins to fix the anal tube to the bed sheet, which is a cumbersome process that wastes manpower. The use of pins also poses a safety hazard. To avoid these problems, the anal tube further includes a clamp 400, which is disposed outside the tube body 100. During use, after the nurse completes the anal tube insertion operation, the clamp 400 can be used to quickly fix the tube body 100 to the bed sheet.

[0040] Furthermore, the clamp 400 is configured to be movable along the length of the pipe body 100 to cope with different usage scenarios. Specifically, the clamp 400 includes an elastic collar portion 401 and a clamping portion 402. The elastic collar portion 401 is sleeved on the outside of the pipe body 100, the inner surface of the elastic collar portion 401 is interference-connected with the outer wall of the pipe body 100, and the clamping portion 402 is fixedly connected to the elastic collar portion 401. During use, the collar portion can be radially expanded along the pipe body 100 and adjusted to a suitable position along the length of the pipe body 100. The collar portion can then be loosened, reset, and squeezed and fixed to the outside of the pipe body 100, thereby adjusting the position of the clamp 400 on the pipe body 100. Preferably, there are two clamping parts 402, one clamping part 402 is provided on each radial side of the tube body 100, and the clamping part 402 is circular, which can avoid being hurt by sharp edges. The elastic ring part 401 is a rubber band.

[0041] Existing anal canals lack a scale display, making it difficult for nurses to determine the depth of anal canal insertion. To avoid this problem, graduated markings 500 are further provided on the outer wall of the tube body 100. These markings 500 are arranged along the length of the tube body 100 and, in conjunction with the scale on the tube body 100, facilitate the nurse's observation of the overall placement of the anal canal and determine whether the anal canal has shifted. In one embodiment of the present invention, the spacing between adjacent graduated markings 500 is 1 cm.

[0042] To facilitate connection with an enema device or rectal administration, the anal tube further includes: a three-way valve 600, which is located at the exposed end 102 of the tube body 100, and one end of the three-way valve 600 is connected to the exposed port 1021.

[0043] Usage: After the operator inserts the insertion end 101 of the tube body 100 into the patient's anus, he gently pushes the entire tube body 100 into the patient's rectal cavity until the external expansion piece 200 is completely inserted into the anus by 2 cm to 3 cm. It is then fixed externally with tape. A negative pressure drainage device is connected to the exposed end 102 of the tube body 100. Turning the three-way valve can add a liquid inlet, allowing enema operations or rectal medication operations.

[0044] The anal tube has the following advantages: 1. After the expansion piece 200 absorbs water and expands, the body increases in size but does not compress the anal sphincter, and does not cause abnormal function of the anal sphincter; 2. The production cost of the expansion piece 200 and the anal tube is low, and the overall unit price of the utility model is not very high, which is easily accepted by most patients; 3. The relative position of the expansion piece 200 and the tube body 100 is fixed, and there is an external scale mark 500, so the operator can clearly observe the insertion depth of the anal tube, and the nurse can clearly observe whether the anal tube is prolapsed when patrolling the ward; 4. The clamp 400 can facilitate the operator to complete the rapid fixation after the entire indwelling anal tube is placed, saving the preparation time of additional pins and rubber bands before the operation, and avoiding the potential danger of pins.

[0045] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention cannot be limited by these embodiments alone. That is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
