[0034] The working principle and process of this utility model are as follows: Specific Implementation Example 1:

[0035] An adult patient undergoing anorectal surgery was admitted to the hospital ward and required the use of the aforementioned multifunctional anorectal gas and stool collection device. Based on the postoperative anastomosis and the examination of the patient's anus and rectum depth, the medical staff determined to use a 14Fr diameter drainage tube 14 and an insertion depth of 13cm into the patient's rectum. The multifunctional anorectal gas and stool collection device with a matching tube diameter was removed, the packaging was removed, and each component was aseptically sterilized. According to the volume scale 7, approximately one-third of the volume of the box 4 was filled with physiological saline. The box lid 5 was placed on the box 4, and the four side fasteners 6 were used to secure the box under the action of the sealing strip. Seal the body 4, put the collection tube 11 into the bolt, and insert it into the round hole 9 together. Adjust the length of the collection tube 11 inserted into the box body 4 to ensure that one end of the collection tube 11 extends below the surface of the physiological saline. Tighten the bolt to seal the collection tube 11 and the round hole 9. Put the internal thread I 12 end of the collection tube 11 into the external thread I 28 end of the reducer 24 and tighten to seal the connection. Put the internal thread II 19 end of the drainage tube 14 into the external thread II 29 end of the reducer 24 and tighten to seal the connection. According to the length scale 15, put the sterile lubricating sleeve 31 onto the round tube body 30 at the front end of the drainage tube 14, and the length of the sleeve should be longer than 13cm.

[0036] Medical staff slowly insert the drainage tube 14 into the patient's anus and rectum, with an insertion length of 13cm, to assist the patient in expelling stool and gas, reducing abdominal distension, and decreasing toxin absorption. The patient's gas expulsion is observed by observing the bubbles that emerge, and the patient's defecation status and nature are observed by observing the stool flowing into the tube and box 4. The difference in volume before and after the rise of the saline water level is read by the volume scale 7, and the number of bowel movements is recorded each time. This allows for timely monitoring of the patient's gastrointestinal motility, facilitating timely adjustments to diet and fluid replacement by medical staff. The biomimetic perianal fitting design of the flexible sealing ring 16 perfectly seals and fits the patient's perianal area. As the patient's posture changes, the flexible sealing ring 16 also changes with the perianal area, maintaining a sealed state and preventing air and liquid leakage throughout the process. The composite superabsorbent resin 18 can absorb the liquid at the contact point between the perianal area and the drainage tube 14 through the micropores 17, avoiding discomfort caused by local dampness.

[0037] Under normal circumstances, when the micro air pump 22 is in standby mode, the exhaust gas, fecal odor and harmful substances enter the activated carbon filter 20 through the exhaust port 10 for preliminary filtration. After passing through the exhaust pipe 21 and the channel of the micro air pump 22, the preliminarily filtered gas is discharged to the waste gas collection device 23 to prevent pollution of the surrounding environment. When the feces are not discharged smoothly, turn on the micro air pump 22 and adjust it to the appropriate level to use the micro air pump 22 for active suction to improve the efficiency of gas and feces collection.

[0038] The inner walls of the reducing adapter 24, drainage tube 14, and collection tube 11 are all coated with a hydrophobic coating 25 made of medical-grade silicone, which effectively prevents feces and liquid from adhering and reduces bacterial growth. When the walls of the reducing adapter 24 and collection tube 11 are covered with a lot of excrement after long-term use, in order to prevent blockage, medical personnel unscrew the sealing cap 27, use a thicker needleless syringe to insert into the branch tube 26, and rinse with physiological saline. After rinsing, the sealing cap 27 is placed on the opening of the branch tube 26 and screwed in to secure it. The rinsing process is complete. At the same time, the hydrophobic coating 25 on the inner walls of the reducing adapter 24 and collection tube 11 can improve the efficiency and effect of rinsing.

[0039] After the multifunctional anorectal gas and stool collection device is used, medical staff slowly pull the front end of the drainage tube 14 out of the patient's anus and intestine, twist the rear end of the drainage tube 14 in reverse to separate it from the reducer 24, and discharge the solid-liquid mixture in the box 4 through the drain port 8 to a special collection device for further treatment. After the multifunctional anorectal gas and stool collection device is initially cleaned and disinfected, it is sent to the hospital supply center for further processing. The reducer 24, collection box 3 and collection tube 11 are distributed to the department for reuse. If it cannot be used due to special circumstances, the reducer 24, collection box 3 and collection tube 11 are recyclable plastics and are recycled. The remaining parts are disposed of as waste. Specific Implementation Example 2:

[0040] A pediatric patient undergoing anorectal surgery was admitted to the hospital ward. Based on the child's age, postoperative anastomosis depth, and examination results, a 10Fr diameter drainage tube 14 was selected, requiring an insertion depth of 8cm into the patient's anorectal region. A multifunctional anorectal gas and stool collection device matching the diameter of the drainage tube 14 was retrieved. After sterilizing each component, a sterile lubricating sleeve 31 was fitted onto the circular tube 30 at the front end of the drainage tube 14 according to the length scale 15, with the fitted length exceeding 8cm. The medical staff slowly inserted the drainage tube 14 into the child's anorectal region, with an insertion length of 8cm. The remaining operating steps were consistent with those in Specific Embodiment 1. If any abnormality occurred with the drainage tube 14 during the use of the multifunctional anorectal gas and stool collection device, the medical staff removed a drainage tube 14 of the same diameter, sterilized it, screwed it onto the reducing adapter 24, fitted it with the sterile lubricating sleeve 31, and slowly removed the abnormal drainage tube 14, replacing it with a new one.

[0041] When using the multifunctional anorectal gas and stool collection device, the collection box 3 needs to be moved. Medical personnel or caregivers should hold the fixing parts 6 on both sides of the box 4 with both hands to carry it. When collecting fecal samples from the child for testing, observe the child defecating. The medical personnel unscrew the sealing cap 27 and insert the sampling device into the branch tube 26 to collect the feces passing through the reducing adapter 24. After collection, place the sealing cap 27 over the opening of the branch tube 26 and screw it in firmly. The fecal sample collection is complete. The forward angle between the branch tube 26 and the reducing adapter 24 is acute, and the flow direction of the gas and stool is opposite to the direction of the branch tube 26. This is to prevent feces from entering the branch tube 26 during stool collection, which would affect subsequent stool sample collection and the flushing and cleaning if the collection tube 11 and the reducing adapter 24 become blocked.
