Title: Storage and dispensing system of liquid substance
Inventor: INOUE YOSHIAKI
IPC: G01T1/167
Filed: 1994-08-31
Abstract: PURPOSE: To obtain a storage and dispensing system whose safety is enhanced in a handling operation by a method wherein a dispensing machine is operated automatically inside a storage warehouse and a liquid radioactive substance only in a required quantity is dispensed. CONSTITUTION: A storage warehouse 1 keeps a plurality of radiation-source containers 16 in which different kinds of liquid radioactive substances have been housed. In addition, a computer 7 stores the keeping positions of the respective radioactive substances housed in the storage warehouse 1 for every kind, and it automatically controls them for every kind. By the instruction of the computer 7 via a control device 6, a needle tip part 12 for a dispensing machine 5 is operated, and it is moved just above a corresponding container 16-2 . By interlocking with it, a lid 17-2 , for a radiation-source housing warehouse 19 for the storage warehouse 1 is opened.  The tip part 12 pierces through a rubber-film cap for the container 16-2 so as to be moved down to the lower part of a solution surface, and it sucks up a required radiation-source solution only in a prescribed quantity so as to be dropped to a dispensing address container 20. This operation is repeated by the number of operations which has been input to the computer 7. When the dispensing machine 5 is interlocked with the storage warehouse 1 in this manner, a dispensing operation is performed automatically without relying on human hands, an exposure to the radioactive substances is reduced in a takeout operation, and it is possible to prevent the generation of an accident such as the damage of the containers or the like.
