Description

Technical Field

[0001] This utility model relates to the technical field of colonoscopy auxiliary devices in intestinal examinations, and specifically to a colonoscopy anti-leakage device with adjustable intestinal pressure. Background Technology

[0002] Colonoscopy is an examination method in which a colonoscope is inserted through the anus into the ileocecal junction to observe lesions in the colon from the mucosal side. In current technology, after the patient cleanses their intestines, the colonoscope is inserted into the intestinal lumen through the anus. The direction is adjusted by turning a knob until it reaches the ileocecal junction, the closest point to the colon. Then, the endoscope is withdrawn to observe the condition of the intestinal wall. Colonoscopy can meet the examination needs of almost the entire colonic region.

[0003] During a colonoscopy, air or CO2 is injected into the intestinal lumen through a colonoscope to inflate the intestines and facilitate the examination. However, once the gas enters the intestines, it easily flows back out through the anus due to internal pressure. The rectum, located 15cm above the anus, is situated in the pelvic cavity and surrounded by soft tissue. The anus has a sphincter muscle that functions to close the anus. Currently, many colonoscopies are performed under anesthesia. Because muscles relax under anesthesia, gas is more easily expelled. After the gas is expelled, the intestinal lumen collapses, and the intestinal wall wrinkles, making it difficult to observe the intestinal wall and potentially missing lesions such as polyps.

[0004] Therefore, if air leakage occurs during colonoscopy, the only solution is for the assistant to forcefully block the anus with a damp gauze. However, this method cannot completely prevent the gas from flowing out, and the aforementioned missed examinations still frequently occur.

[0005] To address the aforementioned technical problems, Chinese patent applications CN215078311U and CN220293588U both utilize a plug to seal the anus and prevent gas leakage. However, both have drawbacks: one has a cylindrical main structure for preventing gas leakage, while the other has a wide-mouthed plug. Neither can be used for patients with different anal sizes. Furthermore, after insertion, neither can regulate the gas pressure within the intestines. As the gas pressure gradually increases during insertion, without real-time adjustment, the plug may pop out.

[0006] Therefore, a gas-proof device for colonoscopy with adjustable intestinal pressure is needed to solve the above-mentioned technical problems. Summary of the Invention

[0007] The purpose of this application is to provide an adjustable intestinal pressure anti-leakage device for colonoscopy that can adjust intestinal pressure in real time while preventing natural leakage of intestinal gas.

[0008] This application is implemented as follows: an air-leakage prevention device for colonoscopy with adjustable intestinal pressure, characterized in that: it includes an anal plug fixed on a sling, the sling being composed of a front sling and a rear sling integrally connected, a protrusion being provided on the rear sling, an opening being provided on the protrusion, a fixing seat being provided in the opening, and an anal plug being snapped into the fixing seat.

[0009] The anal plug includes a plug body, a plug connected to one side of the plug body, and an insertion hole for inserting a colonoscope is provided in the plug body and the plug body.

[0010] An air duct is also provided in the plug and the plug body. The air inlet of the air duct is located at the plug, and the air outlet of the air duct is located on the plug body.

[0011] The exhaust port is connected to an air duct, and a control valve is installed on the air duct.

[0012] The plug has a tapered structure from bottom to top, which includes a spherical crown-shaped end and a frustum-shaped body. The spherical crown-shaped end is integrally connected to the upper end of the body.

[0013] A sealing layer is wrapped around the plug and connector.

[0014] The center of the bottom surface of the plug extends downward to form a connector, and the aforementioned insertion hole extends into the connector.

[0015] A vent cap is screwed onto the connector. The vent cap is a hollow cylinder with an open top. A threaded screw interface is provided at the center of its bottom surface. The shape of the upper port of the vent cap matches the shape of the bottom surface of the plug body and is padded with a sealing ring. A vent cavity is formed between the vent cap, the connector, and the bottom surface of the plug body. The exhaust port of the aforementioned vent channel is located in the vent cavity.

[0016] An air guide hole is provided on the side wall of the air guide cover, and the air guide hole is connected and communicates with the aforementioned air guide tube.

[0017] The plug body includes at least one sphere.

[0018] The plug body comprises two spheres connected in series, with a groove formed on the lower circumference of the lowermost sphere.

[0019] The aforementioned fixing seat is ring-shaped. The outer ring of the fixing seat is fixedly connected to the opening on the protrusion, and the inner ring of the fixing seat forms a retaining edge, which engages with the retaining groove.

[0020] By implementing the above technical solution, this application, through the air duct, air tube, and control valve, can remove excess intestinal gas in real time according to the intestinal pressure, thereby controlling the intestinal pressure and playing a good regulatory role in the smooth conduct of colonoscopy. This application, by setting a plug and a connector, can adapt to different degrees of anal dilation in different patients. The bulb can be smoothly inserted into the anus and sealed. Therefore, compared with the prior art, this application solves both the air leakage problem and the problem of intestinal pressure regulation during colonoscopy. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Example: Figure 1-3As shown, the anti-air leakage device for colonoscopy with adjustable intestinal pressure includes an anal plug 3 fixed on the sling. The sling consists of a front sling 2 and a rear sling 6 integrally connected. A protrusion 5 is provided on the rear sling 6, and an opening is provided on the protrusion 5. A fixing seat 4 is provided in the opening, and the anal plug 3 is snapped into the fixing seat 4.

[0029] The anal plug 3 includes a plug body, a plug 3-2 connected to one side of the plug body, and an insertion hole 3-1 for inserting a colonoscope is provided in the plug 3-2 and the plug body;

[0030] An air guide channel 3-10 is also provided in the plug 3-2 and the plug body. The air inlet 3-3 of the air guide channel 3-10 is located at the plug 3-2, and the exhaust port of the air guide channel 3-10 is located on the plug body.

[0031] The vent is connected to a venting tube, on which a control valve is installed. By opening and closing the control valve, the flow of gas through the venting channel 3-10 can be controlled, thereby controlling the amount of gas in the intestine and consequently, the intestinal pressure. To facilitate the monitoring of intestinal pressure, a pressure gauge can be installed on the venting tube upstream of the control valve.

[0032] Furthermore, connectors are provided at both ends of the diaper, which may be a binding rope 1 or other connectors suitable for this application. The diaper can be fixed to the human body by the connectors, thereby facilitating the insertion of the anal plug 3 into the anus and positioning the anal plug 3, preventing the anal plug 3 from sliding outward under intestinal pressure.

[0033] Furthermore, the plug 3-2 has a tapered structure from bottom to top, comprising a spherical crown-shaped end and a frustum-shaped body, with the spherical crown-shaped end integrally connected to the upper end of the body. This tapered structure allows the patient's anus to be gradually enlarged from small to large, enabling the body to adapt to the subsequent insertion of the plug and making full preparations for its insertion.

[0034] Furthermore, a soft sealing layer 3-9 is wrapped around the outer surface of the plug, and the sealing layer 3-9 can be made of silicone. Since the intestinal wall has many folds, it is difficult to completely seal the plug with a smooth surface alone. Therefore, the sealing layer 3-9 can make the contact area between the plug and the intestinal wall more effective, and further improve the effect of preventing natural gas leakage.

[0035] Furthermore, the sealing layer 3-9 can extend upwards to the plug 3-2 and wrap around it. Since the degree of anal dilation varies among different patients, some patients can only access the plug 3-2. Therefore, to ensure a tight seal, a sealing layer 3-9 is also provided on the plug 3-2.

[0036] Furthermore, the center of the bottom surface of the plug extends downward to form a connector 3-11, which is provided with an external thread. The aforementioned insertion hole 3-1 extends into the connector, and the lower port of the insertion hole 3-1 is the lower port of the connector 3-11.

[0037] Furthermore, a vent cap 3-8 is screwed onto the connector 3-11. The vent cap 3-8 is a hollow cylinder with an open top. A screw-in interface with internal threads is opened at the center of its bottom surface. The shape of the upper port of the vent cap 3-8 matches the shape of the bottom surface of the plug body and is padded with a sealing ring. A venting cavity is formed between the vent cap 3-8, the connector 3-11, and the bottom surface of the plug body. The exhaust port of the aforementioned venting channel 3-10 is located in the venting cavity.

[0038] Furthermore, an air guide hole 3-7 is provided on the side wall of the air guide cover 3-8, and the air guide hole 3-7 is connected and communicates with the aforementioned air guide tube.

[0039] This application uses a rear drape 6 to cover the buttocks and perineum, and a front drape 2 to cover the lower abdomen and lower side. For men, the front drape 2 covers the external genitalia; for women, the connection between the front drape 2 and the rear drape 6 covers the external genitalia. This application uses a connector to fix the entire unit to the waist and hip area, so that the anal plug 3 is positioned corresponding to the anus, and the protruding strip 5 can be locked in the groin for positioning.

[0040] During the examination, first, connect the anal plug 3 to the fixing base 4. Then, insert the plug 3-2 of the anal plug 3 into the anus, and gradually push the plug further in according to the patient's condition until the anal opening is completely blocked. Afterward, use the connector to fix the front diaphragm 2 and the rear diaphragm 6 to the patient's waist, hips, and buttocks to secure the anal plug 3. Then, insert the colonoscope into the intestine through the insertion port 3-1 and perform the examination according to medical standards.

[0041] During this process, if the intestinal pressure is high and signs of air leakage or outward movement of the anal plug are found, the control valve can be opened to release the air. The intestinal gas enters through the air inlet of the air duct 3-10 and is discharged into the air duct cavity through the air outlet, and then discharged through the air duct tube, thereby regulating the intestinal pressure to facilitate the smooth conduct of the examination.

[0042] like Figure 2 , 3 As shown, in another embodiment of this application, the plug includes at least one sphere, the diameter of which is larger than the maximum diameter of the plug 3-2. Setting the plug as a spherical structure eliminates sharp edges, allowing it to enter the intestine more smoothly and avoiding scratching or damage to the intestinal wall.

[0043] Since the sealing performance of a single sphere may be insufficient, it is preferable that two spheres are connected in series in this application, and a groove 3-6 is formed on the lower circumference of the lowermost sphere.

[0044] The aforementioned fixing seat 4 is a ring structure. The outer ring of the fixing seat 4 is fixedly connected to the opening on the protrusion 5. The inner ring of the fixing seat 4 forms a snap-edge structure. The ball can be fixed in the mounting seat 4 by the cooperation of the snap-edge and the slot 3-6.

[0045] The above technical features constitute the embodiments of this application, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.
