[0002] In order to safely drain the accumulated fluid in the patient's abdominal cavity, it is often necessary to use a leak-proof ascites puncture and drainage device. The invention patent with patent application number CN202011350182.7 discloses a thoracic puncture and drainage device, which adopts a spherical opening and closing bead and a valve core spring to achieve one-way conduction, which is convenient for driving the second one-way valve to control the normal flow; and it can better adapt to the operation of syringe suction and injection of accumulated fluid, and the operation process is reliable. The first one-way valve adopts a diaphragm structure, and the rubber support leather cup provides elastic support force, has a small automatic opening force, and is convenient for fluid to pass through. The rubber support leather cup is bowl-shaped, which can better To prevent backflow, the drainage tube body is extended after insertion to increase the coverage area of ​​the drainage site. At the same time, because there are often solid foreign bodies such as sloughed tissue in the pleural effusion, which block the internal opening, the entire drainage tube needs to be replaced. This design can prevent the frequent replacement of the drainage tube caused by this situation. When injecting the drug, the speed control switch can be used to close the pipeline connection of the drainage tube behind the injection branch to achieve reliable injection of the drug into the chest cavity. The invention patent with patent number CN201810998854.1 discloses a puncture drainage needle with adjustable flow rate. The handheld component is convenient for medical staff to hold and pinch, and it is convenient to apply force. The adjustment group is set The device is convenient for users to adjust the discharge flow rate according to various symptoms. As the driving ring rotates, the sealing sheets are no longer sealed when they are fitted together, and a through hole is formed. The through hole can also be enlarged or reduced, so that the discharge flow rate of the accumulated fluid can be adjusted to avoid some symptoms where the fluid is discharged too quickly, resulting in a rapid decrease in the air pressure in the patient's body and causing physical discomfort. It can also avoid the secondary infection and increased trauma mentioned in the background technology. At the same time, the first slider and the second slider are arranged to facilitate the sliding of the sealing sheet. The driving ring is convenient for users to adjust the flow rate. The cooperation of the guide groove and the slide groove can form a through hole of variable size between multiple sealing sheets. According to the disclosed technical solution, when the existing anti-leakage ascites puncture and drainage equipment is used, on the one hand, the inner diameter of the puncture and drainage needle is generally very small, which is easily blocked by the thick matter in the ascites, which is not conducive to ensuring the normal discharge of ascites; on the other hand, when the ascites is discharged, it is easy for the pressure in the human body to cause the ascites discharge pressure to be too high, which is not conducive to ensuring the osmotic pressure balance of the person; on the other hand, when the ascites discharge pressure is adjusted, the ascites outflow rate is easily unstable due to pressure changes, which is not conducive to ensuring the stable drainage of ascites.

The more the pressure of the ascites increases, the more the gate in the lower bend pipe is moved out, the more ascites flows through the lower bend pipe, the greater the resistance to the ascites, and in turn offsets the outflow pressure of the ascites, thereby effectively ensuring the stability of the outflow pressure of the ascites, and thus effectively ensuring the stability of the osmotic pressure in the personnel body, avoiding the osmotic pressure imbalance caused by the rapid drop in the pressure of the ascites, and ensuring the safety of the personnel.

Then hold the fixed envelope 1 and draw out the pus through the disposable needle tube, and inject physiological saline to ensure that the pipeline is normal. Then pull out the steel needle 7 and use the elasticity of the plug 5 in the envelope 1 to seal it. Then the effusion in the abdominal cavity enters the envelope 1 through the hose 6 and is then led out through the catheter 2. This prevents the steel needle 7 from damaging the internal organs when people are moving, ensures the safety of the patient, and facilitates the patient to carry out the required activities. If there is sticky matter or lumps in the accumulated water that block the hose 6, the pressure in the abdominal cavity will be used to make the accumulated water flow into the inner side of the annular groove 9 through the inclined hole 8, and then the pressure will be used to squeeze the soft ring 10, so that the accumulated fluid will enter the inner side of the hose 6, avoiding the accumulation of fluid that cannot be discharged due to the blockage of the hose 6, and ensuring the smooth drainage of the accumulated fluid. When it is necessary to use normal saline to dilute the abdominal cavity accumulation again, the pressure of the normal saline will be used to make the soft ring 10 block the inclined hole 8, and then effectively clean the hose 6, avoiding ensuring the discharge speed of the ascites.

[0021] In this embodiment, the bottom end of the hose 6 is connected to the top of the envelope 1, one end of the conduit 2 is connected to one side of the top of the envelope 1, the main pipe 16 is provided with an inner side of an adjusting plate 11, one end of the main pipe 16 is connected to the other end of the conduit 2, one end of the connecting pipe 12 is connected to the other end of the main pipe 16, the other end of the connecting pipe 12 is connected to one side of the drainage bag 13, and a discharge port 14 is installed on the other side of the drainage bag 13. A valve 15 is installed on the discharge port 14 and on one end of the connecting pipe 12. The upper bend 17 and the lower bend 18 are both provided with the inner side of the adjusting plate 11. Both ends are connected to the main pipe 16, one end of the upper bend pipe 17 and the lower bend pipe 18 is aligned with the flow direction of the main pipe 16, and the angle between the other ends of the upper bend pipe 17 and the lower bend pipe 18 and the inner flow direction of the main pipe 16 is greater than 90 degrees. The connecting groove 19 is respectively provided on the inner side of the two ends of the regulating plate 11, and both ends of the main pipe 16 are connected to the inner side of one end of the connecting groove 19. The outer side of the piston 20 is stuck on the inner wall of one end of the connecting groove 19, and a support block 21 is provided on the inner wall of the other end of the connecting groove 19. When in use, the ascites enters the inner side of the main pipe 16 in the regulating plate 11 through the catheter 2, and flows along the main pipe 16 in the regulating plate 11. The fluid flows in the section plate 11 and then enters the inner side of the drainage bag 13 through the connecting tube 12. The valve 15 in the discharge port 14 is opened as needed, or the drainage bag 13 is replaced to ensure that the ascites can be completely discharged. If the discharge pressure of the ascites is large, the pressure in the connecting groove 19 on the right side of the regulating plate 11 is large, and then the piston 20 compresses the spring 1 23 under the pressure of the ascites to move, and pushes the pure water in the connecting groove 19 to the inner side of the inner groove 25 through the through tube 26, and then the gate 27 in the inner groove 25 compresses the spring 2 28 under the push of the pure water, and connects the lower bend pipe 18 with the main pipe 16, and under the inertia action, the lower bend pipe 18 is connected to the main pipe 16.

The greater the pressure of the ascites, the more the gate 27 in the lower bend pipe 18 is moved out, the more ascites flows through the lower bend pipe 18, and the greater the resistance to the ascites, which in turn offsets the outflow pressure of the ascites, thereby effectively ensuring the stability of the outflow pressure of the ascites, thereby effectively ensuring the stability of the osmotic pressure in the personnel body, avoiding the osmotic pressure imbalance caused by the rapid drop in the pressure of the ascites, and ensuring the safety of the personnel.

[0022] When using the intelligent pressure-regulating and leak-proof ascites puncture and drainage device, unplug the card cover 4, connect the disposable needle tube with the bottom end of the steel needle 7, then unplug the needle cap 3, hold the disposable needle tube and insert the steel needle 7 into the ascites, the steel needle 7 drives the hose 6 to be inserted into the ascites, then hold the fixed envelope 1, and extract the pus through the disposable needle tube, and inject physiological saline to ensure that the pipeline is normal, then pull out the steel needle 7, and use the elasticity of the plug 5 in the envelope 1 to seal it, so that the accumulated fluid in the abdominal cavity enters the envelope 1 through the hose 6, and then is led out through the catheter 2, so as to avoid the situation where the steel needle 7 damages the internal organs when people are active, ensure the safety of the patient, and facilitate the patient to carry out the required activities. If there is viscous matter or lumps in the accumulated water blocking the hose 6, use the abdominal cavity The pressure inside causes the accumulated water to flow into the inner side of the annular groove 9 through the inclined hole 8, and then the pressure is used to squeeze the soft ring 10, thereby causing the accumulated fluid to enter the inner side of the hose 6, avoiding the inability to discharge the accumulated fluid due to blockage of the hose 6, and ensuring the smooth drainage of the accumulated fluid. When it is necessary to use normal saline to dilute the ascites again, the pressure of the normal saline is used to make the soft ring 10 block the inclined hole 8, thereby effectively cleaning the hose 6, avoiding ensuring the discharge speed of ascites. The ascites enters the inner side of the main pipe 16 in the regulating plate 11 through the catheter 2, flows along the main pipe 16 in the regulating plate 11, and then enters the inner side of the drainage bag 13 through the connecting pipe 12. Open the valve 15 in the discharge port 14 as needed, or replace the drainage bag 13 to ensure that the ascites can be completely drained. Discharge, if the discharge pressure of the ascites is large, the pressure in the connecting groove 19 on the right side of the regulating plate 11 is large, and then the piston 20 compresses the spring 1 23 to move under the pressure of the ascites, and pushes the pure water in the connecting groove 19 to the inner side of the inner groove 25 through the through pipe 26, and then the gate 27 in the inner groove 25 compresses the spring 2 28 to move under the push of the pure water, and makes the lower bend pipe 18 connected with the main pipe 16. Under the action of inertia, a part of the ascites enters the lower bend pipe 18, and then flows into the main pipe 16 in the opposite direction of the flow direction of the main pipe 16, which creates resistance to the flow of the ascites and reduces the flow speed of the ascites. The greater the pressure of the ascites, the more the gate 27 in the lower bend pipe 18 is moved out, and the ascites is discharged. The more ascites that flows through the lower bend 18, the greater the resistance to the ascites, which in turn offsets the outflow pressure of the ascites, thereby effectively ensuring the stability of the outflow pressure of the ascites, and thus effectively ensuring the stability of the osmotic pressure in the personnel body, avoiding the osmotic pressure imbalance caused by the pressure drop of the ascites too quickly, and ensuring the safety of the personnel. When the ascites flows to the inner side of the left end of the regulating plate 11, if the flow rate of the ascites is large, the piston 20 located on the left side of the regulating plate 11 is subjected to a large pressure, and then the gate 27 in the upper bend 17 is opened, and the flow rate of the ascites in the main pipe 16 is blocked again, which can effectively ensure the stability of the flow rate of the ascites. At the same time, according to the weight, age, and other conditions of the personnel,The screw rod 24 is then adjusted, thereby adjusting the position of the support block 21 within the connecting groove 19, and thereby adjusting the pressure exerted by the support block 21 on the piston 20 via the spring 1 23. This allows the piston 20 to move at a constant pressure, thereby adjusting the movement distance of the gate 27. This allows the drainage speed of the ascites to be adjusted according to different needs. Compression prevents significant changes in the drainage speed of the ascites due to pressure changes, thereby ensuring the stability of the drainage speed of the ascites.
