[0028] The medicine cutting mechanism 3 includes a medicine cutting rotating ring 31, which is rotatably mounted on the medicine guiding tube body 12, and the top of the medicine cutting rotating ring 31 is in contact with the bottom of the medicine administering tube body 11, and the top of the medicine cutting rotating ring 31 and the bottom of the medicine administering tube body 11 are both damping structures, and a limiting clamp ring 310 is integrally formed at the inner lower end of the medicine cutting rotating ring 31, and a limiting ring groove 116 is provided on the outer wall of the medicine guiding tube body 12, and the limiting clamp ring 310 is rotatably clamped in the limiting ring groove 116, and the limiting clamp ring 310 and the limiting ring The coordinated use of the groove 116 provides a guarantee for the stable rotation of the medicine cutting ring 31. The medicine cutting ring 31 is connected with a symmetrically distributed U-shaped catheter 32, and the bottom end of the drug delivery tube body 11 is penetrated with a medicine delivery guide hole 114 used in conjunction with the U-shaped catheter 32.

When the injection of the corresponding medicine is completed, the driving ring 311 needs to be pulled to the side away from the mounting sleeve 34, so as to drive the fixed plug rod 37 to move, and then drive the sliding ring 35 to move and squeeze the second spring 36, and when the fixed plug rod 37 is completely separated from the corresponding fixed plug hole 115, the driving ring 311 is stopped from being pulled and rotated, so as to drive the cutting of the medicine. The rotating ring 31 rotates, thereby driving the U-shaped catheter 32 and the drug storage cylinder 33 to rotate, until the drug storage cylinder 33 storing the drug solution is rotated to correspond to the drug delivery guide hole 114, and then the driving ring 311 is stopped and loosened. At this time, the second spring 36 will drive the fixed plug rod 37 to reset, so that the fixed plug rod 37 can be inserted into another corresponding fixed plug hole 115, and then the drug delivery push plate 16 is pulled up and the position of the first wedge block 27 is adjusted according to the above steps, so that another required injection drug solution can be sucked into the drug delivery tube body 11, and then the drug cutting rotating ring 31 is reset and the injection operation of another drug solution is performed according to the above steps.

[0032] Working principle: When in use, hold the drug-delivery tube 11 and sleeve the drug-delivery needle 13 on the bottom end of the drug-delivery tube 12, then insert the drug-delivery needle 13 into the drug solution that any patient needs to inject, and then push the L-shaped elastic rod 24, so that the first wedge block 27 can be driven to move to the side away from the drug-delivery tube 11, and when the distance between the first wedge block 27 and the drug-delivery tube 11 moves to the maximum, pull up the drug-delivery push plate 16, so that the drug-delivery push rod 15 can be driven to move upward, and then the rubber piston 14 can be driven to move upward, and further the corresponding drug solution can be sucked into the drug-delivery tube 11. When an appropriate amount of drug solution is sucked into the drug-delivery tube 11, stop pulling the drug-delivery push plate 16 and release the L-shaped elastic rod 24. At this time, the L-shaped elastic rod 24 will drive the first wedge block 27 to reset, and then The L-shaped elastic rod 24 is then moved upward, thereby driving the limit rod 26 to move upward and stretch the first spring 22. When the limit rod 26 is completely separated from the corresponding limit plug hole 111, the L-shaped elastic rod 24 is stopped from being moved upward and rotated, thereby driving the first wedge block 27 and the mounting turntable 23 to rotate, and then driving the first spring 22 and the mounting swivel 21 to rotate. When the first wedge block 27 rotates to the position of the second wedge block 28, the third wedge block 29 or the fourth wedge block 210 that matches the corresponding liquid injection rate, the L-shaped elastic rod 24 is released. At this time, the first spring 22 will drive the mounting turntable 23 to move downward and reset, thereby driving the L-shaped elastic rod 24 to move downward and reset, and then the limit rod 26 can be inserted into another corresponding limit plug hole 111.
[0033] Then, according to the amount of injection liquid, one or two blocking tube covers 39 are turned and removed, and then an appropriate amount of the remaining injection liquid required is introduced into the corresponding medicine storage cylinder 33, and then the blocking tube cover 39 is reversed and reset. At this time, the blocking tube cover 39 will drive the corresponding mixing rotating rod 41 to rotate, thereby driving the corresponding installation ring 42 to rotate, and then driving the corresponding mixing blade 43 to rotate, and further the corresponding liquid medicine can be fully mixed and stirred;
[0034] After that, the medication needle 13 is inserted into the part of the patient where the medication solution is to be injected and the medication push plate 16 is pushed to reset, so that the medication push rod 15 can drive the rubber piston 14 to reset, and then the corresponding medication solution can be injected into the corresponding position in the patient's body. During this period, the medication push plate 16 will synchronously drive the L-shaped elastic rod 24 to reset, thereby driving the first wedge block 27 to reset, and then the first wedge block 27 can slide along the corresponding second wedge block 28, the third wedge block 29 or the fourth wedge block 210 in sequence, and further, the vibration time difference generated by the first wedge block 27 contacting the second wedge block 28, the third wedge block 29 or the fourth wedge block 210 with different spacings can be used to prompt the medical staff the current injection rate of the medication solution, without the need for the medical staff to make subjective estimates, thereby effectively improving the accuracy of the medication solution injection rate, and thus providing convenience for the operation and use of the medical staff;
[0035] When the injection of the corresponding drug solution is completed, the driving collar 311 needs to be pulled to the side away from the mounting sleeve 34, so as to drive the fixed plug rod 37 to move, and then drive the sliding collar 35 to move and squeeze the second spring 36, and when the fixed plug rod 37 is completely separated from the corresponding fixed plug hole 115, the driving collar 311 is stopped from being pulled and rotated, so as to drive the medicine cutting ring 31 to rotate, and then drive the U-shaped catheter 32 and the drug storage cylinder 33 to rotate, until the drug storage cylinder 33 storing the drug solution is rotated to the side aligned with the drug delivery guide hole 114. The driving ring 311 should be stopped and loosened in time. At this time, the second spring 36 will drive the fixed plug rod 37 to reset, so that the fixed plug rod 37 can be inserted into another corresponding fixed socket 115. Then, the medication push plate 16 is pulled up and the position of the first wedge block 27 is adjusted according to the above steps, so that another required injection liquid can be sucked into the medication tube body 11. Then the medicine cutting ring 31 is reset and the injection operation of another liquid is carried out according to the above steps. If there is a third liquid to be injected, the above steps can be followed to replenish the medicine and inject it.
