7. a kind of use such as mixed prescription method as claimed in any one of claims 1 to 6 based on the pouring-in online medicament-mixing device of minute-pressure,
Characterized by comprising the following steps:
According to user's input and the matched water medicine ratio of Crop Group, the water of corresponding flow and the medicine input mixed prescription member are taken
(5)；
The control assembly obtains the water flow data of first flow sensor and the medical abortion amount from second flow sensor
Data, when the water flow or variant medical abortion amount of the water flow data or the medicine data on flows and theory, described in adjusting
The revolving speed of water pump or killer injecting pump to practical water flow or the medical abortion amount meets the water medicine ratio.
8. the mixed prescription method according to claim 7 based on the pouring-in online medicament-mixing device of minute-pressure, which is characterized in that also wrap
Include following steps:
The control assembly obtains the pressure value in the mixed prescription from the pressure sensor first (5), when the pressure value is low
When the minute-pressure threshold value of setting, the medical abortion amount of the water flow and medicine-taking component that adjust the water intaking component makes the mixed prescription member
(5) pressure value in is equal to or higher than the minute-pressure threshold value of setting.
9. the mixed prescription method according to claim 7 or 8 based on the pouring-in online medicament-mixing device of minute-pressure, which is characterized in that
It is further comprising the steps of:
The high water tank data of the first liquid level sensor and the medicine-chest liquid level data of the second liquid level sensor are obtained, when the water tank
The liquid level perhaps medicine-chest liquid level lower than corresponding calibration minimum liquid level when stop working, alarm or fill the water or injection.
