The application discloses a kind of intravenous infusion apparatus, it is related to infusion apparatus technical field.The present application includes Murphy drip tube, one end is equipped with second hose, the other end is equipped with first hose, and first hose is used to connect with infusion
bottle.The present application is connected with infusion
bottle by first hose, installation shell is installed below Murphy drip tube, when liquid
medicine moves to installation shell when using,
first pass liquid inlet chamber, liquid
medicine in liquid inlet chamber passes through
buoyancy and makes air bag drive baffle to rotate to remove the shielding of through hole, so that liquid
medicine can enter into liquid outlet chamber, at this time, also through
buoyancy and make empty bag ball float, when the liquid medicine in infusion
bottle is finished, the
buoyancy of liquid in liquid inlet chamber is less than the gravity of empty bag ball, so that empty bag ball will be the
nozzle of third hose is shielded, reduce the possibility of
air movement to third hose and further affect the safety of patient, increase the safety of device when using.
