Tube Connection Apparatus
First Claim
1. A tube connection apparatus for connecting a tube member to a chemical solution container which contains a chemical solution, and an opening of a container body of the chemical solution container being sealed by an elastic member, comprising:
- a container holding mechanism for holding the chemical solution container removably, with the opening located above;
a short tubular needle member having a proximal end and a distal end, the proximal end being connected removably to a liquid supply tube in which a liquid with a specific gravity lower than that of the chemical solution flows, the distal end penetrates the elastic member;
a long tubular needle member having a proximal end and a distal end, the proximal end being connected removably to a chemical solution injection tube in which the chemical solution flows, the distal end penetrates the elastic member;
a holder member for holding the short needle member and the long needle member, with their proximal ends located above and their distal ends located below;
a holder moving mechanism for moving the short needle member and the long needle member vertically, together with the holder member, between a retraction position above and an insertion position below; and
a container moving mechanism for supporting the chemical solution container together with the container holding mechanism to be movable horizontally, between an insertion position where the chemical solution container faces the short needle member and the long needle member from below at a insertion position, and, a retraction position where the chemical solution container does not face them.

Abstract
A tube connection apparatus enabling the connection of tube members to a chemical solution container for a radioactive contrast medium with exposure of a operator to the radiation minimized. When the container (400) is loaded to a container holding mechanism (315) located at a retreat position, the container (400) is moved to a needle insertion position by a container moving mechanism (310) and short/long needle members (341, 342) are moved to the insertion position by a holder moving mechanism (320). Since the short/long needle members (341, 342) are inserted into the elastic member (402) of the chemical liquid container (400) without requiring manual operation by a operator, a liquid supply tube (120) and a chemical solution injection tube (130) can be connected to the container (400) with the exposure of the operator to radiation minimized.
