Abstract
A liquid outflow control unit used in an instrument for injecting a liquid such as a liquid medicine into a human body. It includes a plurality of separate partial members, at least one of which has a groove on a joined face thereof to form a small path through which a liquid passes. A liquid enters one end of the groove and goes out of an exit which fluid communicates with the other end of the groove. The liquid flowing out of the exit is injected into the human body via a connection tube and a needle.
