The two groups of vertical plates 21 can be clamped on the armrests of the infusion chair, and then the two groups of threaded knobs 22 are passed under the armrests. The device can be fixed on the infusion chair to prevent the infusion pipeline from being pulled by the large-scale movement of the child's arm.

[0064] like Figure 2 , 4 As shown in Figures 5 and 6, in this embodiment, a mounting groove 14 is provided at the end of the shell 1, a through groove 18 and a plurality of through holes 15 are provided on the shell 1, a movable block 3 is slidably arranged in the mounting groove 14, a massage part is eccentrically arranged in the plurality of through holes 15, and the massage part includes a massage plate 41, the massage plate 41 is liftably arranged in the through hole 15, a plurality of massage columns 43 are arranged on the massage plate 41, and the massage columns 43 protrude out of the through holes 15 after the massage plate 41 rises.

[0065] In the initial state, the massage plate 41 is retracted into the through hole 15 to avoid long-term contact with the palm of the child. After a long period of infusion, the child can use the fingers to move the movable block 3, thereby driving the movable block 3 to slide in the mounting groove 14 to move the finger joints, thereby avoiding discomfort caused by blood stagnation due to long-term immobility of the finger joints. A baffle 17 is provided on the inner side of the shell 1, and an elastic member 31 is provided between the baffle 17 and the movable block 3. When the movable block 3 is pressed, the elastic member 31 can be squeezed, and the movable block 3 is reset by the reset control of the elastic member 31.

[0066] like Figures 5 to 7As shown, in this embodiment, a driving mechanism connected to multiple groups of massage parts is provided on the movable block 3, and the sliding of the movable block 3 is converted into driving the massage parts to rise and protrude outside the through hole 15 through the driving mechanism, and the multiple groups of massage parts are driven to revolve and rotate. The driving mechanism includes a first lifting seat 5 that can be lifted and lowered and arranged in the shell 1, and a movable plate 4 that can move circumferentially is arranged on the first lifting seat 5. Multiple groups of massage discs 41 are rotatably arranged on the movable plate 4. A first driving component connected to the first lifting seat 5 is provided on the movable block 3.

[0069] During the sliding process of the movable block 3, the rack 33 is driven to translate. During the movement of the rack 33, the third gear 57 can be driven to rotate. During the lifting process of the first lifting seat 5, the positioning post 56 slides along its axis on the third gear 57, so that the first lifting seat 5 can still drive the second gear 55 to rotate through the third gear 57 after lifting. During the rotation of the second gear 55, the two groups of first gears 53 are driven to rotate synchronously. During the rotation of the two groups of first gears 53, the movable plate 4 can be driven to perform a circumferential translation motion along a circular track through the two eccentrically arranged connecting posts 54, so as to drive the multiple massage discs 41 to revolve along the edge of the through hole 15 in the through hole 15, so as to massage the palm muscles through the massage posts 43, stimulate the palm nerves, and reduce the discomfort caused by long-term infusion.

[0070] As Figure 2 , 4 shown, in this embodiment, the driving mechanism further includes a third driving component arranged in the through hole 15 and connected to the massage disc 41, and the revolution of the massage disc 41 is converted into driving the massage disc 41 to rotate by the third driving component.
