Example Embodiment

[0052] Example 1

[0053] Such as figure 1 with figure 2 As shown, the manual filling equipment for infusion soft bags of the present invention includes a liquid supply device, the liquid supply device is provided with a liquid outlet nozzle 1, a valve 2 is provided on the liquid outlet nozzle 1, and the liquid supply device includes a liquid inlet pipe 3, and At least two liquid outlet branches 4 connected with the liquid inlet pipe 3, each of the liquid outlet branches 4 and the liquid inlet pipe 3 is provided with a flow meter 5, the signal input of the flow meter 5 and the PLC controller 10 The signal output terminal of the PLC controller 10 is connected to the valve 2, and each liquid outlet branch 4 is connected with at least one liquid outlet nozzle 1.

[0054] Among them, the liquid supply device can provide the entire device with liquid medicine for filling. The liquid supply device includes a liquid inlet pipe 3, and the liquid inlet pipe 3 on the liquid supply device can be connected to a liquid medicine source, such as a water delivery system of a pharmaceutical factory, or a liquid medicine storage tank, etc., and can continuously supplement the liquid medicine to Its inside.
