Furthermore, an on-off key, a zero clearing key and an alarm key are arranged on the display device, the on-off key is used for opening an electronic display screen on the display device, the zero clearing key is pressed when the infusion bag is hung, the weight of the hook and the influence of the infusion bag can be eliminated, and the alarm key can be manually pressed to remind medical workers to replace the infusion solution.

Preferably, the zero clearing key has three zero clearing modes, and the weights of three infusion bags of 100ml, 250ml and 500ml can be selected to be cleared in advance according to different volumes of the infusion bags.

Furthermore, the infusion support is a suspension type infusion support, and the suspension type infusion support can be used in public infusion places of hospitals to better utilize space.

Preferably, when a suspended infusion support is adopted, a lifting hook is arranged below the lifting rod and penetrates through a hanging opening in the top of the infusion bag to be connected with the infusion bag.

Preferably, in order to prevent the infusion bag from being scratched, the lifting hook is a right-angle type lifting hook.

Furthermore, the infusion support is of a hollow structure, so that a rope and a pressure sensor can be arranged inside the infusion support, the pressure sensor is also of a hollow structure, small holes are formed in the upper surface and the lower surface of the pressure sensor, and the rope on the lower side can penetrate through the small holes to be connected with the lifting hook.

Furthermore, the diameter of the small hole is smaller than that of the metal disc, the metal disc can generate a squeezing effect on the pressure sensor, the pressure of the metal disc on the sensor is equal to the gravity of the residual liquid, and therefore the residual liquid weight data can be collected by the pressure sensor and then transmitted to the display device to be displayed.

Compared with the prior art, the utility model has the following beneficial effects:

1. the residual fluid infusion amount is accurately calculated, the fluid infusion speed is controlled, and the safety of a patient is guaranteed.

2. Low price and convenient installation.

3. Automatic induction reminding fluid infusion.
