Description

Technical Field

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

[0002] Gastric lavage is a medical procedure, also known as gastric lavage or gastric pump lavage. It is usually performed in hospitals or medical institutions to empty the stomach of food, poisons or other harmful substances. A large proportion of children are currently poisoned by accidental injuries, and it is also a common disease in pediatric digestive clinics, mostly in infants and preschoolers. To deal with this disease, it is necessary to use a gastric lavage device to wash the child's stomach.

[0003] Existing gastric lavage devices are mainly divided into single-tube and double-tube types. Single-tube gastric lavage requires two syringes to be prepared and used alternately after completing the last filling and suction process, which is cumbersome to operate. Double-tube gastric lavage uses two tubes for filling and suction. Although the operation is more convenient, the filling and suction volume is balanced when filling and suctioning at the same time. Since children's stomachs are relatively fragile, unbalanced filling and suction volume can easily lead to other side effects. Secondly, children's throat tubes are relatively small, and it is more painful for patients to insert double tubes. For this reason, we propose a gastric lavage device for pediatric digestive clinics. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing gastric lavage device in the prior art maintains a balance in the amount of filling and suction during simultaneous filling and suction.

The inner diameter of the diverter 8 and the inner diameter of the diverter port 801 are equal to the diameter of the connecting tube 5. When in use, the design of the inner and outer cavities prevents the gastric juice flow channel and the cleaning liquid flow channel from interfering with each other.

[0045] like Fig.10As shown, a diverter port 801 is provided at the top of the diverter 8 and the diverter port 801 is connected to the outer cavity of the diverter 8. The diverter port 801 and one end of the inner cavity of the diverter 8 are respectively fixedly connected to two gastric lavage barrels 3 with connecting pipes 5. The other end of the diverter 8 is fixedly connected to the gastric lavage tube 6. The outer cavity of the diverter 8 is provided with a plurality of plug connectors 802 adapted to the flushing hole 601 in a ring shape near one end of the gastric lavage tube 6. When in use, the cleaning liquid is injected into the outer cavity of the diverter 8 through one of the connecting pipes 5, and is injected into the flushing hole 601 of the gastric lavage tube 6 through the plug connector 802. At the same time, the gastric fluid is drawn into the inner cavity of the diverter 8 through the gastric lavage tube 6, and is drawn into the gastric lavage barrel 3 through another connecting pipe 5.

[0046] The specific working principle is to insert the mouthpiece tube 701 into the mouth of the child patient, and hang the elastic bands 704 on both sides on the ears of the child patient. After wearing, insert the gastric lavage tube 6 through the mouthpiece tube 701 into the stomach of the child patient. After the insertion is completed, rotate the knob 702 to drive the abutment 705 to move up until the stomach of the gastric tube is clamped. After the tube is inserted, connect the gastric tube to the shunt 8;

[0047] The worm 101 is rotated by rotating the handle, and the rotation of the worm 101 drives the shaft 401 to rotate through the meshing action with the worm wheel 403, and the rotation of the shaft 401 drives the transmission rod 404 to rotate and makes one end of the transmission rod 404 higher than the other end, and the two gastric lavage barrels 3 are placed in the barrel seat 201 and pressed down, and during the pressing process, the first screw cover 301 is rotated and tightened to fix the gastric lavage barrels 3, and the two gastric lavage barrels 3 are connected to the connecting pipe 5 and connected to the gastric lavage tube 6 through the diverter 8, and one of the gastric lavage barrels 3 is filled with a cleaning solution for gastric lavage, and the other gastric lavage barrel 3 is empty (the gastric lavage barrel 3 filled with the cleaning solution is placed on the high end of the transmission rod 404, and the empty gastric lavage barrel 3 is placed on the low end of the transmission rod 404);

[0048] After the installation is completed, gastric lavage begins. The worm 101 is rotated in the opposite direction. The shaft 401 rotates and the sliding action of the slider 406 and the slide groove on the transmission rod 404 drives the two connecting rods to move up and down respectively. The movement of the connecting rod drives the piston 402 to move to form positive and negative pressure. The cleaning liquid in the gastric lavage barrel 3 filled with cleaning liquid is discharged, enters the outer cavity of the diverter 8 through the connecting pipe 5, and then passes through and is injected into the flushing hole 601 of the gastric lavage tube 6 through the plug connector 802, and finally enters the gastric lavage head 602 through the flushing hole 601 and is discharged from the through hole 603 on the gastric lavage head 602;

[0049] A negative pressure is formed in the empty gastric lavage bucket 3, and the gastric juice in the stomach of the child patient is drawn into the gastric lavage tube 6 through the through hole 603 on the cleaning head, then enters the inner cavity of the diverter 8 from the gastric lavage tube 6, and finally is drawn into the empty gastric lavage bucket 3 through the connecting tube 5 for storage.
