[0024] As Figure 2 shown, a rubber isolation layer 23 is arranged on the inner wall of the vibration tube body 10 near the tapping chamber 22. A through hole is arranged at the junction of the rubber isolation layer 23 and the transmission rod 16. The rubber isolation layer 23 can prevent the liquid medicine from spilling outwards.

[0025] As Figures 4 - 7 shown, the anti-disassembly component 3 includes a magic tape 24, an anti-disassembly connecting rod 25, a fixed block 26, a wrapping ball 27, a dosing container 28, a dosing screw cap 29, an electrorheological fluid 30, a parallel plate capacitor 31, and a plastic wrapping layer 32. There are two groups of magic tapes 24. One end of the anti-disassembly connecting rod 25 is fixedly arranged on the two groups of magic tapes 24. The fixed block 26 is fixedly arranged at the other end of the anti-disassembly connecting rod 25. The fixed block 26 is fixedly arranged on the conduit 1. The wrapping ball 27 is fixedly arranged on the fixed block 26. An arm placement opening is arranged on the wrapping ball 27. The dosing containers 28 are communicatively arranged around the wrapping ball 27 in an array. The dosing screw cap 29 is arranged on the dosing container 28. The plastic wrapping layer 32 is communicatively arranged on the dosing container 28. The parallel plate capacitors 31 are arranged in pairs opposite to each other on the plastic wrapping layer 32. The electrorheological fluid 30 is arranged in the dosing container 28; A control button 33 is further arranged at the end of the plastic wrapping layer 32. The control button 33 is electrically connected to the parallel plate capacitor 31.

[0026] The plastic wrapping layer 32 is made of silica gel material.

[0027] The plastic wrapping layer 32 is arranged inside the wrapping ball 27.

[0028] During specific use, insert the puncture head 7 into the infusion bottle. The liquid medicine is input through the catheter 1 to the infusion needle 5. Evacuate the gas in the catheter 1 to prevent it from entering the human body. Put the child's forearm into the magic tape 24. According to the puncture position of the infusion needle 5, adjust the position of the magic tape 24. Put the child patient's hand into the wrapping ball 27, and guide the child patient to put the palm in a comfortable position. When the child patient's palm just enters the wrapping ball 27, there is no electrorheological fluid 30 in the dosing container 28, and there is also no electrorheological fluid 30 in the plastic wrapping layer 32. At this time, the plastic wrapping layer 32 cannot extend and expand towards the dosing container 28, and the control button 33 cannot touch the child patient's palm through the plastic wrapping layer 32. At this time, open the dosing screw cap 29 and add the electrorheological fluid 30 to each group of dosing containers 28. The electrorheological fluid 30 flows into each group of plastic wrapping layers 32. The electrorheological fluid 30 conforms to the shape of the child patient's palm through the plastic wrapping layer 32. Multiple groups of plastic wrapping layers 32 can conform to the child patient's palm from different angles. At this time, the control button 33 touches the child patient's palm through the plastic wrapping layer 32, making the internal circuit conduct, and discharging between the parallel plate capacitors 31. The electrorheological fluid 30 changes from a liquid state to a solid state. The surface of the plastic wrapping layer 32 made of silica gel is soft and insulating, while the internal electrorheological fluid 30 is in a solid state, making the child patient's palm unable to move, and at the same time ensuring the comfort of the child patient, and can be adaptively fixed according to the different sizes of the palms of different child patients; Perform the puncture work on the child patient's forearm. The liquid medicine flows downward into the drip chamber control component 4 and continues to flow downward. When the liquid medicine drops into the vibrating tube body 10, the liquid medicine pushes the rotating fan 13 to rotate. The rotating fan 13 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the rotating member one 14 to rotate around the rotating shaft 12. The rotating member one 14 drives the rotating member two 15 to rotate around the rotating shaft 12. The rotating shaft 12 drives the transmission rod 16 to reciprocate. The transmission rod 16 drives the linkage block 17 to reciprocate. The linkage block 17 drives the tapping connecting rod 20 to reciprocate. The child patient's skin near the puncture is tapped through the tapping contact plate 21, and the pain is relieved through small-amplitude vibration. Until after the infusion is completed, pull out the infusion needle 5, disconnect the internal circuit, make the electrorheological fluid 30 return to the liquid state again, and then the child patient's palm can be taken out. Open the magic tape 24 and take out the child patient's forearm.
