The connection pipe 12 is pressed and closed by squeezing the fixed sealing block 206 and the movable sealing block 207.

[0022] Working principle: During the use of the utility model, the configured liquid medicine is first sucked into the syringe, and then the syringe is connected to the large flow connector 13, and the large flow connector 13 is used to realize the rapid injection of the liquid medicine, and the liquid medicine is injected into the first rubber valve 5, and then the liquid medicine is injected into the first infusion tube 4, and then the liquid medicine is injected into the configuration bag 1 to realize the configuration of the liquid medicine. After the configuration is completed, the large flow connector 13 is removed. When it is necessary to discharge the liquid according to the needs of the child, the limit block 302 in the sealing mechanism 3 is broken along the breaking groove 306, and after breaking, it continues to be along the fixed cylinder 304. The sealing sleeve 301 is rotated to drive the sealing sleeve 301 to rotate along the fixed cylinder 304 toward the baffle 303, and then the fixed thorn head 305 is driven to rotate and feed. As the fixed thorn head 305 rotates and feeds, the sealing film 307 is rotated and punctured. At this time, the liquid in the configuration bag 1 enters the first infusion tube 4, then enters the fixed cylinder 304, then enters the sealing sleeve 301, and then enters the connecting tube 12, and then enters the liquid discharge measuring cylinder 202. The liquid is discharged by the liquid discharge measuring cylinder 202, and the second scale 201 on the liquid discharge measuring cylinder 202 is used to accurately measure the liquid. The amount of liquid discharged is measured, which improves the accuracy of liquid discharge. There is no need for multiple suctions, which avoids cross contamination. When the liquid discharge is completed, the hand wheel 211 in the closed liquid discharge mechanism 2 is turned. The rotation of the hand wheel 211 drives the threaded rod 210 to rotate. Since the threaded rod 210 is fixedly connected to the threaded block 209 by threads, the threaded rod 210 moves along the threaded block 209 toward the fixed closed block 206, and then drives the movable closed block 207 to move toward the fixed closed block 206. The movable closed block 207 and the fixed closed block 206 are used to achieve the compression and fixation of the connecting pipe 12. It is beneficial to ensure the sealing of the connecting tube 12 and avoid the backflow of the medicine. At this time, the first scale 9 on the configuration bag 1 is used to measure the remaining medicine in the configuration bag 1, and then the inlet and outlet pipes 8 and the second rubber valve 7 are used for infusion. The fixed rubber 11 is used to install the hanging hole 10, the second fixed block 208 is used to install the threaded block 209, the first fixed block 205 is used to install the fixed sealed block 206, the connecting rod 203 is used to connect and fix the first fixed block 205 and the second fixed block 208, and the limiting cylinder 204 is used for the limiting installation of the first fixed block 205 and the second fixed block 208.
