Description

Technical Field

[0001] The invention relates to the technical field of gastric lavage devices, in particular to a negative pressure gastric lavage device for pediatrics. Background Art

[0002] The pediatric negative pressure gastric lavage device is a medical device specially used in pediatrics, mainly used for gastric lavage on children. The advantage of this device is that it can effectively remove unabsorbed poisons in the stomach or clean the stomach cavity. It is clinically used for gastric surgery and preparation before examination. For acute poisoning, such as swallowing organic phosphorus, inorganic phosphorus, alkaloids, barbiturates, etc. in a short period of time, gastric lavage is an important rescue measure.

[0003] For example, announcement number CN111744069B is a pediatric negative pressure gastric lavage device for pediatrics. This invention can control the flow rate of the liquid in the pipeline and the pressure of the suction pump and the flushing pump, thereby controlling the speed of pumping and spraying liquid to avoid damage to the child's stomach. The gastric tube is an integrated combination structure, which avoids multiple intubations and causes discomfort to the child. The gastric lavage liquid can be heated and stirred to keep the gastric lavage liquid at a constant temperature, reducing irritation to the stomach caused by temperature discomfort, and facilitating the cleaning of the sewage tank and the storage of the gastric tube after use. In addition, the device is easy to move, has a compact and reasonable structure, is easy to use, and effectively improves the efficiency of gastric lavage.

[0004] When the negative pressure gastric lavage device in the above scheme is used, it is necessary to send the gastric lavage liquid into the stomach of the child through the liquid pump, and then flush the stomach. After the flushing is completed, the debris in the flushed stomach is sucked out by the negative pressure pump and sent to the sewage tank, so as to complete the gastric lavage. However, when performing gastric lavage, the gastric lavage liquid needs to be prepared. Generally, solutions such as physiological saline, potassium permanganate, and sodium bicarbonate solution are mixed with clean water. When preparing the solution, the above scheme can only prepare it externally and then send it to the storage tank. When other gastric lavage devices with mixed drugs on the market mix the gastric lavage liquid, it is necessary to introduce the drug liquid into the storage tank before each mixing, and then make it pass through the mixing mechanism in the mixing tank. Mixing with clean water is cumbersome, and it is difficult to automatically and quantitatively add the medicine, which affects the speed of preparing the medicine in the gastric lavage device. In addition, the medicine is generally added at a single point and is difficult to evenly enter the gastric lavage device. When a child undergoes gastric lavage, the existing gastric lavage device will first deliver the gastric lavage solution to the child's stomach through a delivery tube, and then extract the debris in the stomach through a liquid extraction tube, and this cycle is repeated many times. However, in order to prevent discomfort to the child, the delivery tube is always left in the stomach. Therefore, some debris will enter the delivery tube, resulting in the inability of the liquid extraction tube to extract the debris in the stomach cleanly. When the delivery tube delivers the gastric lavage solution again, the debris will be brought into the stomach again, thereby failing to complete the complete cleaning of the stomach.

One side of the connecting sleeve 273 is provided with multiple groups of oblate grooves matching the blocking block b276.

[0037] In specific implementation, the pediatric negative pressure gastric lavage device needs to prepare the gastric lavage solution before performing gastric lavage on children, and clean water is injected into the storage tank 3 through the water filling pipe 26. As the water level in the storage tank 3 rises, the float plate 12 will be pushed to float up. When the float plate 12 floats up, it will drive the rack rod 13 on the top to move. When the rack rod 13 contacts the transmission gear 14, it will mesh with it, thereby driving the transmission gear 14 to rotate. When the transmission gear 14 rotates, it will drive the transmission shaft 16 on one side to rotate, so that the rubber sleeve 20 and the connecting ball 21 connected to one end of the transmission shaft 16 also rotate. At this time, the connecting ball 21 will flip 180°, so that the internal medicine delivery cavity 22 originally facing upwards turns to the bottom, and the medicine delivery cavity 22 faces upwards. The liquid medicine in the storage chamber 18 will be taken when the storage chamber 18 rotates to the bottom, and the taken liquid medicine can be sent to the medicine spraying mechanism 25 through the delivery pipe 24 to complete the quantitative addition of the liquid medicine. The side of the rubber sleeve 20 facing the top will block the storage chamber 18 at this time, and the liquid medicine will flow through the delivery groove a251 and be input into the connecting hose 252, and finally be introduced into the delivery groove b255 inside the rotating rod 253 through the connecting hose 252. Since the rotating rod 253 is in an inclined state when the stirring rod 10 is not rotating and is limited by the limiting frame 254 at the bottom, the liquid medicine will gather in the movable groove 259 at the end of the rotating rod 253. At this time, since the blocking ball 257 is in close contact with the end of the rotating rod 253, the liquid medicine will not flow out.

[0038] When the connecting ball 21 rotates 180°, the tooth surface on the rack rod 13 will disengage from the transmission gear 14, and the rack rod 13 will continue to move up, thereby contacting the touch button 15. At this time, the touch button 15 will send a signal to the controller 2, and the controller 2 will control the motor 7 to start. The motor 7 will drive the driving gear 8 at the bottom to rotate, so that the driving gear 8 is engaged with the driven gear 9, thereby driving the stirring rod 10 connected to the bottom of the driven gear 9 to rotate. When the stirring rod 10 rotates, it will stir the inside of the storage tank 3 and drive the rotating rod 253 to rotate as well. When the rotating rod 253 rotates, it will rotate to a state perpendicular to the stirring rod 10 under the action of centrifugal force. At this time, the ball 258 at the end of the rotating rod 253 will alternately contact with the multiple groups of protrusions 2510 on the inner wall of the storage tank 3 during continuous rotation. When the ball 258 contacts the protrusion 2510, the ball 2 58 will move and squeeze the blocking ball 257 on one side, and the blocking ball 257 will squeeze the spring 256 on one side to make it shrink. The blocking ball 257 will shrink into the conical movable groove 259, so that a gap will be generated at the end of the rotating rod 253. At this time, the liquid medicine gathered in the movable groove 259 will be thrown out under the action of centrifugal force, and then enter the storage tank 3 to mix with the clean water inside. When the ball 258 is out of contact with the protrusion 2510, the spring 256 will push the blocking ball 257 to reset and re-seal the end of the rotating rod 253. At this time, the liquid medicine in the rotating rod 253 will not flow out. In this way, through the alternating contact between the ball 258 and the multiple groups of protrusions 2510, the liquid medicine carried by the rotating rod 253 can be evenly delivered to the storage tank 3, thereby completing the uniform addition of the liquid medicine, improving the uniformity of the gastric lavage solution preparation, and thus improving the effect of gastric lavage;

[0039] The motor 7 will stop rotating after rotating for a fixed time, at which time the stirring rod 10 will also stop rotating, and the rotating rod 253 will also rotate and reset accordingly, and contact the limit frame 254 at the bottom. Since the rotating rod 253 will be in a tilted state under normal conditions, it will not contact the protrusion 2510, thereby preventing the end of the rotating rod 253 from flowing out when the medicine is poured. The medicine will only be evenly sprinkled when the stirring rod 10 rotates. When the gastric lavage liquid in the storage tank 3 is drawn out, the floating plate 12 will move downward, thereby driving the rack rod 13 to move downward as well. The downwardly moved rack rod 13 will drive the transmission gear 14 and the transmission shaft 16 to reverse, thereby resetting the rubber sleeve 20 and the connecting ball 21. The reset medicine delivery chamber 22 will face the top again, thereby receiving the medicine in the storage chamber 18 and preparing for the next medicine filling.

[0040] When it is necessary to adjust the filling amount of each medicine liquid, by rotating the threaded rod 231 in the adjustment mechanism 23, the threaded rod 231 will be threadedly driven with the medicine storage box 17, so as to move downward, and the downwardly moving threaded rod 231 will drive the piston block 232 to slide in the piston sleeve 233, thereby pressurizing the liquid in the piston sleeve 233, so that the liquid enters the cavity inside the connecting ball 21 through the connecting pipe 234, and at this time, the rubber sleeve body 236 at the top of the cavity will expand, occupying the space of the medicine delivery cavity 22, thereby reducing the volume of the medicine delivery cavity 22, and at this time, the filling amount of each medicine liquid will be reduced, so that the adjustment of the automatic medicine addition amount each time can be completed;

[0041] When performing gastric lavage on a child, the delivery pump 6 can be started to extract the gastric lavage liquid in the storage tank 3 through the extraction tube 11 and input it into the delivery hose 271. The delivery hose 271 will deliver the gastric lavage liquid into the connecting sleeve 273. The pressurized gastric lavage liquid will push the multiple groups of blocking blocks a275 and b276 to move them away from the blockage on one side of the connecting sleeve 273. The sliding rod 274 will limit the moving blocking blocks a275 and b276, and the blocking blocks a275 and b276 will pull the tension spring 277 to stretch when moving. At this time, the liquid medicine in the connecting sleeve 273 will be sprayed out, but the sprayed liquid medicine will first contact the blocking block b276, and the blocking block b276 will be pressurized. The gastric lavage liquid is slowed down so that it enters the stomach more gently, and the blocking block b276 diffuses the gastric lavage liquid outward so that the gastric lavage liquid is evenly delivered to the stomach, thereby evenly cleaning the child's stomach. When the liquid medicine is input, the tension spring 277 will reset, thereby pulling the blocking blocks a275 and b276 to reset, and re-blocking one side of the connecting sleeve 273. At this time, the discharged gastric lavage liquid will not enter the connecting sleeve 273 again. By starting the negative pressure pump 5, the negative pressure pump 5 will extract the debris in the stomach through the extraction hose 272. In this way, the liquid medicine in the negative pressure gastric lavage device can be automatically prepared through the above operation, and the gastric lavage liquid can be evenly delivered to the child's stomach.

[0042] In summary, the suction mechanism 27 is sent into the child's stomach, and then the delivery pump 6 is started to input the gastric lavage solution in the storage tank 3 into the child's stomach to clean the stomach. After the cleaning is completed, the negative pressure pump 5 is started to extract the debris in the stomach. After repeating this operation multiple times, the gastric lavage of the child can be completed. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
