Document Type and Number:

Japanese Patent JP3608984

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a compact apparatus for continually injecting medicinal solution causing no transient rise in flow velocity just before the end of medicinal solution.
SOLUTION: This apparatus for continually injecting a medicinal solution has a chemical inlet 7, a balloon 1, and a chemical outlet 8. The balloon is filled with medicinal solution and expanded and deformed to use the contracting force of the balloon as a driving force for feeding the medicinal solution.
