[0018] 3. The sponge is adhered to the inside of the heating plate to avoid direct contact between the heating plate and the outside of the infusion tube. The sponge is soft to prevent the infusion tube from being squeezed and affecting normal drainage, thus protecting the infusion tube;

[0019] 4. The threaded rod rotates to move the push rod forward, and the push rod pushes the fixed rod, thereby moving the fixed rod to the middle position. The moving distances of the fixed rod can be different by different push rod moving distances, thereby making the distances between the fixed rods on the left and right sides different, and infusion tubes with different diameters can be clamped and heated;

[0031] When the weather is cold and the infusion needs to be heated, the threaded rod 10 is rotated by hand, and the threaded rod 10 rotates to move the push rod 11 forward and backward. When the push rod 11 moves to the front side to the inclined edge of the fixed rod 8 to make contact, the push rod 11 moves to push the fixed rod 8, and the fixed rod 8 moves to the middle position to drive the heating plate 13 and the sponge 14 to move synchronously. When the sponge 14 moves to the infusion tube to make contact, the threaded rod 10 is no longer rotated, and the heating temperature of the heating plate 13 is adjusted by the button on the recorder 1. The temperature sensor 12 monitors the temperature of the heating plate 13, and then displays the temperature through the display screen 2. The heating plate 13 heats the infusion medicine body to avoid the phenomenon that the temperature of the medicine liquid is too low and makes the patient uncomfortable.
