<p>PURPOSE:To suck transfusion liquid in a transfusion liquid vessel into a drip bottle so as to enable it to be charged with the liquid by accommodating the drip bottle in an air-tight tank and reducing its internal pressure to suck air in the drip bottle under a condition that a transfusion liquid charting hollow needle, mounted to the other end of a gathering liquid pipe, and an air vent hollow needle are pierced through a rubber plug of the drip bottle. CONSTITUTION:An air bleed hollow needle 8 and a transfusion liquid charging hollow needle 9a of a gathering liquid pipe 9 are pierced through a drip bottle 4 being accommodated in an air-tight tank 1, and a through hole 7a is closed by a rubber packing 10 while inserting the gathering liquid pipe 9 into the through-hole 7a of a cap member 7. Under a condition that a hollow needle 9b in another end side of the gathering liquid pipe 9 is immersed in a drug (transfusion liquid) of a drug bottle (transfusion liquid vessel) 11, when a vacuum pump 2 is operated, air in the air-tight tank 1 is sucked through an exhaust pipe 3 reducing a pressure, and sucking air in the drip bottle 4, accommodated in the air-tight tank 1, through the air vent hollow needle 8, pierced into a rubber plug 4a, into the air-tight tank 1, the drip bottle 4 is reduced in its internal pressure almost equal to the air-tight tank 1. The transfusion liquid vessel 11 under the atmospheric pressure and the drip bottle 4 are connectd by the gathering liquid pipe, so that the drug is sucked into the drip bottle 4 by a pressure difference between the vessel and the bottle.</p> |
