[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, this utility model provides a clinical ascites drainage device for gastroenterology, including an ascites drainage device body 1. The ascites drainage device body 1 includes an ascites drainage device shell 101, an anti-slip base 102 at the bottom of the ascites drainage device shell 101, a negative pressure drainage pump 103 on the side of the ascites drainage device shell 101, a drainage tube 104 connected to the input end of the negative pressure drainage pump 103, and a puncture needle 105 at one end of the drainage tube 104. A reinforcement and leak-proof component 2 is provided at the connection between the drainage conduit 104 and the negative pressure drainage pump 103. The reinforcement and leak-proof component 2 includes a reinforcement ring 201, which is located at the connection between the negative pressure drainage pump 103 and the drainage conduit 104. A first reinforcement block 202 is provided at one end of the reinforcement ring 201, and a second reinforcement block 206 is provided at the other end of the reinforcement ring 201. A magnetic connecting plate 203 is provided on the first reinforcement block 202, and a groove 2 is provided on the second reinforcement block 206. 05. A protrusion 204 is provided on the magnetic connecting plate 203. A quick-installation component 3 is provided at the connection between the magnetic connecting plate 203 and the first reinforcing block 202. The quick-installation component 3 includes a fixed blind groove 301. A fixing block 310 is provided inside the fixed blind groove 301. A fixed through groove 307 is connected to the side of the inner wall of the fixed blind groove 301. A fixing buckle 308, a spring 306 and a transmission rod 303 are provided inside the fixed through groove 307. A slot 302 is connected to one end of the fixed through groove 307. The outer shell 101 of the ascites drainage device can protect the internal structure. The anti-slip base 102 can improve the stability of the device placement and prevent the device from sliding during the drainage process and affecting the operation. The negative pressure drainage pump 103, the drainage tube 104 and the puncture needle 105 work together to achieve efficient drainage of ascites and meet the clinical needs of gastroenterology. The reinforcing and leak-proof component 2 can enhance the sealing and firmness of the connection between the drainage tube 104 and the negative pressure drainage pump 103.

[0020] Specifically, the groove 205 and the protrusion 204 engage with each other. The protrusion 204 is located at the bottom of the magnetic connecting plate 203. The engagement of the groove 205 and the protrusion 204 enables the magnetic connecting plate 203 to be quickly positioned and connected with the second reinforcing block 206. Combined with the magnetic attraction of the magnetic connecting plate 203, the closing firmness of the reinforcing ring 201 is further enhanced, preventing the reinforcing ring 201 from loosening. This improves the sealing effect at the connection between the drainage tube 104 and the negative pressure drainage pump 103, preventing ascites leakage.

[0021] Furthermore, the fixing block 310 is provided with a fixing slot 309, which engages with the fixing buckle 308. The engagement of the fixing slot 309 and the fixing buckle 308 can achieve stable fixing of the fixing block 310 inside the fixing blind groove 301, thereby firmly fixing the magnetic connecting plate 203 on the first reinforcing block 202 and preventing the magnetic connecting plate 203 from falling off.

[0022] Furthermore, a limiting plate 305 is fixedly installed at the connection between the fixed through groove 307 and the slot 302. The limiting plate 305 is provided with an insertion hole 304. The limiting plate 305 can limit the fixing buckle 308 and spring 306 inside the fixed through groove 307, preventing them from falling out of the fixed through groove 307 and ensuring the structural integrity of the quick-installation assembly 3. The insertion hole 304 provides a through channel for the transmission rod 303, ensuring that the transmission rod 303 can move smoothly and providing a guarantee for the extension and retraction adjustment of the fixing buckle 308.

[0023] It is worth noting that one end of the transmission rod 303 is fixedly connected to the fixing buckle 308, and the other end of the transmission rod 303 passes through the insertion hole 304 into the slot 302. This allows for quick engagement and disengagement of the fixing buckle 308 and the fixing slot 309, thereby enabling quick assembly and disassembly of the magnetic connection plate 203, saving equipment assembly and maintenance time, and improving clinical operation efficiency.

[0024] It is worth noting that one end of the spring 306 is fixedly connected to the fixing buckle 308, and the other end of the spring 306 abuts against the limiting plate 305. The fixing buckle 308 is limited inside the fixing through groove 307 by the limiting plate 305. The spring 306 can provide a continuous elastic force to the fixing buckle 308, pushing the fixing buckle 308 to be tightly engaged with the fixing groove 309, ensuring that the fixing block 310 is firmly fixed and preventing it from loosening during use.

[0025] It is worth mentioning that the fixing block 310 is slidably connected inside the fixing blind groove 301, and the fixing buckle 308 is slidably connected inside the fixing through groove 307. The slidable connection between the fixing block 310 and the fixing blind groove 301 facilitates the quick insertion or removal of the fixing block 310 from the fixing blind groove 301, providing convenience for the assembly and disassembly of the magnetic connecting plate 203. The slidable connection between the fixing buckle 308 and the fixing through groove 307 ensures that the fixing buckle 308 can flexibly extend and retract, achieving precise engagement and disengagement with the fixing buckle 309.

[0026] It is worth emphasizing that the bottom of the fixing block 310 is designed with a slope, and there are two fixing blind slots 301. The two fixing blind slots 301 are designed symmetrically. The fixing block 310 is fixedly connected to the magnetic connecting plate 203. The slope design of the bottom of the fixing block 310 can guide the fixing block 310 to be quickly and smoothly inserted into the fixing blind slot 301, reducing the difficulty of disassembly and assembly. The two symmetrically designed fixing blind slots 301 cooperate with the fixing block 310 to make the connection between the magnetic connecting plate 203 and the first reinforcing block 202 evenly stressed, avoiding excessive local stress that could damage the components and further improving the connection firmness.

[0027] The ascites drainage device housing 101, anti-slip base 102, negative pressure drainage pump 103, drainage catheter 104, and puncture needle 105 are existing technologies and will not be described in detail here. Meanwhile, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this application.

[0028] Working principle and process: When using this gastroenterology clinical ascites drainage device, first install the magnetic connecting plate 203 and the first reinforcing block 202 using the quick-release assembly 3. Then, insert the fixing block 310 into the fixing blind groove 301. The inclined surface at the bottom of the fixing block 310 presses against the fixing buckle 308, causing the fixing buckle 308 to slide in the fixing through groove 307 and compress the spring 306. When the fixing block 310 is fully inserted into the fixing blind groove 301, the spring 306 returns to its original position and pushes the fixing buckle 308 into the fixing slot 309 on the fixing block 310, thus fixing the magnetic connecting plate 203 and the first reinforcing block 202. Subsequently, the reinforcing ring 201 is fitted onto the connection between the negative pressure drainage pump 103 and the drainage catheter 104, causing the protrusion 204 on the magnetic connecting plate 203 to engage with the groove 205 on the second reinforcing block 206. Through the magnetic attraction of the magnetic connecting plate 203, the first reinforcing block 202 and the second reinforcing block 206 are tightly fitted together, thereby firmly fixing the reinforcing ring 201 at the connection, thus providing reinforcement and preventing leakage. The anti-slip base 102 is placed on a flat surface to prevent the ascites drainage device body 1 from sliding during operation. The negative pressure drainage pump 103 is started, generating negative pressure suction, which draws out the ascites from the patient's body through the drainage catheter 104 and the puncture needle 105, completing the ascites drainage operation. To disassemble the magnetic connecting plate 203, press the transmission rod 303 in the slot 302. The transmission rod 303 will drive the fixing buckle 308 to compress the spring 306 and disengage from the fixing slot 309, so that the fixing block 310 can be pulled out from the fixing blind slot 301, achieving quick disassembly.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
