How to exhaust

How can we achieve the purpose of rapid exhaust during intravenous infusion? The method required for exhaust is as follows: coil the lower section of the infusion tube of Murphy's dropper in your hand and lift it up, so that the Murphy's dropper turns upward and opens the infusion tube regulator. When the liquid flows into the Murphy's dropper to 1/3, close the regulator, and then put down the infusion tube in your hand. After a small amount of air under the Murphy's dropper automatically escapes to the liquid surface in the Murphy's dropper, open the regulator to make the liquid flow down in drops instead of in a line. Because the pressure in a line is high, the gas in the upper part of the Murphy's dropper can be pressed into the lower section of the tube to form more bubbles; when the medicine flows out of the needle, the regulator can be pushed upward to the bottom of the Murphy's dropper and closed to achieve the purpose of exhaust.
