When infusion, why does infusion bottle (plastic) become deformed?
If you say that the plastic bottle has been deflated, the bottle of liquid is not flowing, indicating that the pressure in the bottle is not balanced, the air inlet is blocked, then it is clean, called the nurse to help you solve the problem.
Let (intake pipe flow, ensure the gas can enter, in order to ensure the liquid can flow out, or bubbling gas (infusion flow shut, pinch drip chamber, repeatedly, to see if we can break through the inlet, but not blowing, your mouth tone not clean, or replace the infusion tube to plunge needle.)
In the infusion, there is a needle in the bottle, but he is a double mouth, one is used to drain the liquid in the bottle, and the other is that the liquid in the bottle is lost and the pressure is reduced into the air to supplement the pressure balance in it.
