In addition, a storage bag is provided at the bottom of the rectangular frame 31, and parents can put some sundries in the storage bag for easy access.

[0033] The working process of the child safety infusion chair is as follows: A child sits on the leather-covered sponge cushion 13 of the infusion chair base 1, and the infusion hanging rod 4 suspends an infusion bottle to infuse the child. If the child needs to adjust the backrest angle, the servo drive motor 27 operates, and its output shaft drives the worm wheel 28 to rotate through a coupling. The worm wheel 28 meshes with the worm 29, causing the worm 29 to drive the rotating shaft 23 to rotate. Since the bottom end of the movable piece 24 is inserted into the U-shaped connecting seat 22 and is fixedly connected to the outer surface of the rotating shaft 23, the backrest 26 rotates around the rotating shaft 23 to achieve the adjustment of the backrest angle. The limit blocks at both ends of the rotating shaft 23 prevent it from falling off the inside of the U-shaped connecting seat 22 and the movable piece 24.

[0034] When accompanied by parents, the rectangular frame 31 of the parent accompaniment protection mechanism 3 can be pulled open, and the hydraulic support rod 35 expands and contracts to adjust the inclination angle of the rectangular frame 31, facilitating the sitting and lying of parents. The magnet strip 32 at the top of the rectangular frame 31 adsorbs to the front magnetic strip of the side plate 12 to retract the rectangular frame 31. The elastic connecting leather 14 on the rear side of the side plate 12 seals the gap between the side plate 12 and the backrest 26 when the backrest 26 tilts backward. The infusion auxiliary instruments loaded inside the storage drawer cabinet 15 are available for medical staff to use. The front surface above the rear end surface of the back plate 21 contacts and is flush with the rear end surface of the leather-covered sponge cushion 13. The hollowed-out pattern inside the backrest 26 increases air permeability, and the surface color painting attracts the attention of children. The front end corners of the side plates 12 are chamfered to avoid children from bumping, and the sponge thick pads on the side close to each other improve comfort. The top of the convex strip 33 is flush with the bottom of the leather-covered sponge cushion 13, and the pin passes through the round hole of the rectangular frame 31 to achieve the connection.
