Title:
MEDICAL FLUID DILUTING METHOD AND AUTOMATIC MEDICAL FLUID DILUTING DEVICE
Document Type and Number:
Japanese Patent JP3462283
Kind Code:
B2
Abstract:
PURPOSE: To stably supply medical fluid without being influenced by the conditions of a main stream by sucking-in a medical fluid accommodated in a tank by a system separated from a water piping system of the main stream, and dripping the medical fluid to the water piping system of the main stream to be mixed and diluted with water.
CONSTITUTION: A pneumatic ejector 2 connected, for example, to an air source 9 is connected to a tank 1 accommodating a medical fluid through a suction pipe 3, and the ejector sucks in the medical fluid in the tank 1 by negative pressure. On the other hand, a separator 4 is connected to the delivery side of the ejector 2. Further, the delivery side 4a of the separator 4 is connected to an ejector 5 connected to a water piping A of the main stream for mixing the medical fluid, through a check valve 6. Furthermore, the exhaust side 4b of the separator 4 is connected to the tank 1 through an exhaust pipe 7. The mixed fluid mixed with air sucked in by the ejector 2 is allowere to collide with the inside wall of the separator 4. Thus, only the medical fluid weighing mor than air is dripped to separate the medical fluid from air.
