Technical Field

[0001] This utility model relates to the technical field of gastrointestinal irrigation devices, and more specifically, to an anti-backflow irrigation device for gastrointestinal surgery. Background Technology

[0002] Gastrointestinal surgery is a branch of surgery, primarily used before a diagnosis is made. Generally, if a gastrointestinal disease requires surgery, a visit to a gastrointestinal surgeon is necessary. Examples include appendicitis, intestinal obstruction, sigmoid colon cancer, rectal cancer, and hemorrhoids. Because gastrointestinal surgery requires emptying the patient's intestines, this is done by administering a soap and water enema the day before surgery, using pressure to infuse the fluid into the patient's body through an IV drip held high.

[0003] Existing gastrointestinal infusion devices are mostly one-piece designs, requiring replacement after each use to ensure hygiene. However, this replacement process is inconvenient and poses a risk of backflow into the device. Therefore, a backflow prevention infusion device for gastrointestinal surgery is proposed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-backflow irrigation device for gastrointestinal surgery. The technical problem to be solved by the present invention is that the existing gastrointestinal irrigation devices are mostly integrated designs. In order to ensure cleanliness and hygiene during use, they need to be replaced after use. However, the replacement process is not convenient and there is a problem of backflow into the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gastrointestinal surgical anti-backflow irrigation device, comprising an irrigation assembly, wherein a quick-connect assembly is provided on one side of the irrigation assembly, and a snap-fit ​​assembly is fixedly connected to the outer surface of the quick-connect assembly;

[0006] The quick-connect assembly includes a one-way valve, one end of which is fitted with a first connecting sleeve, and the other end of which is fitted with a second connecting sleeve. Studs are fixedly connected to the outer sides of both the first and second connecting sleeves. An inner sleeve is fixedly connected to the side of each stud away from the first and second connecting sleeves. A connecting ring is fixedly connected to the surface of each stud near the inner sleeve. Multiple retaining plates are fixedly connected to the surface of each connecting ring away from the stud. A locking sleeve is rotatably connected to the surface of each stud. A second connecting tube is fitted onto the outer surface of the inner sleeve.

[0007] In a preferred embodiment, the liquid filling assembly includes a liquid storage tube, with fixed posts fixedly connected to both sides of the outer surface of the liquid storage tube, a filling inlet opening at the top of the liquid storage tube, a locking cap rotatably connected to the inner side of the filling inlet, a lifting bar at the top of the liquid storage tube, a sleeve opening through both ends of the lifting bar, a rotating opening through one side of the sleeve opening at both ends of the lifting bar, and a first connecting pipe drivingly connected to the bottom of the liquid storage tube.

[0008] In a preferred embodiment, the snap-fit ​​assembly includes snap-fit ​​blocks, each snap-fit ​​block being fixedly connected to the outer surface of the first connecting sleeve and the second connecting sleeve. Multiple rotating blocks are fixedly connected to the outer surface of the first connecting sleeve and the second connecting sleeve. Each rotating block has a snap-fit ​​opening on its surface and a pressing groove on its surface.

[0009] In a preferred embodiment, the locking plate is tightened after being rotatably connected to the stud via a locking sleeve. The inner sleeve on one side of the first connecting sleeve is connected to the first connecting pipe, and the inner sleeve on one side of the second connecting sleeve is connected to the second connecting pipe.

[0010] In a preferred embodiment, the fixed column is formed by a connecting rod and a limiting plate, the sleeve opening has the same inner diameter as the limiting plate, and the connecting rod has the same width as the rotating opening.

[0011] In a preferred embodiment, the snap-fit ​​block and rotating block provided on the outer surface of the first connecting sleeve are arranged horizontally, and the snap-fit ​​block and rotating block provided on the outer surface of the second connecting sleeve are arranged vertically, wherein the snap-fit ​​block is the same size as the bayonet opening.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by comprising a filling assembly, a quick-connect assembly, and a snap-fit ​​assembly, allows for direct rotation of the locking sleeve on one side of the first connecting sleeve during later use. The locking sleeve is first fitted onto the surface of the first connecting tube, and then the first connecting tube is fitted onto the surface of the inner sleeve on one side of the first connecting sleeve. Rotating the locking sleeve causes its inner wall to intersect with the snap-fit ​​plate, thus pressing the snap-fit ​​plate against the surface of the first connecting tube for fixation. The one-way valve is then rotatably connected to the inner wall of the first connecting sleeve, and the process is repeated in the same manner. After the inner sleeve of the second connecting sleeve is fitted onto the surface of the second connecting tube, the locking sleeve of the second connecting sleeve is rotated and connected to the stud. Then, the first connecting sleeve and the second connecting sleeve are cut into and snapped together. This ensures the stability of the connection by making the snap-fit ​​holes on the inner sides of the multiple rotating blocks snap into the snap-fit ​​blocks. This solves the problem that most existing gastrointestinal irrigation devices are one-piece designs, which require replacement after use to ensure cleanliness and hygiene. However, the replacement process is not convenient and there is a problem of backflow into the device.

[0014] 2. This utility model is equipped with a liquid filling component, which allows for direct selection of the carrying handle or direct hanging of the carrying handle at a high place during later use, ensuring smooth use in the future. Attached Figure Description

Rotating the locking sleeve 28 causes the inner wall of the locking sleeve 28 to intersect with the clamping plate 27, and the clamping plate 27 is pressed against the surface of the first connecting tube 18 by the inner wall of the locking sleeve 28, thus achieving a fixing effect. Then, the one-way valve 21 is rotatably connected to the inner wall of the first connecting sleeve 22, and the second connecting sleeve 23 is then connected in the same manner. After the second connecting tube 29 is fitted onto the surface of the inner sleeve 25 on one side, the locking sleeve 28 on one side of the second connecting sleeve 23 is rotated and connected to the stud 24. Then, the first connecting sleeve 22 and the second connecting sleeve 23 are cut into and snapped together, so that the snap-fit ​​holes 33 on the inner side of the multiple rotating blocks 32 can all snap into the snap-fit ​​blocks 31, thus ensuring the stability of the connection. This solves the problem that existing gastrointestinal infusion devices are mostly one-piece designs, which require replacement after use to ensure cleanliness and hygiene. However, the replacement process is not convenient and there is a problem of backflow into the device. In the future, the carrying handle 15 can be directly selected or the carrying handle 15 can be directly hung at a high place to ensure smooth use in the future.
