Connector, syringe assembly, and connector for mixing
First Claim
1. A mixing connector connectable to a medicine container, which contains medicine and which is positioned in a first port of a holder, and a liquid container, which contains liquid different from the medicine and which is positioned in a second port of the holder possessing a configuration different from a configuration of the first port, the mixing connector comprising:
- a support section;
a double-pointed needle supported in the support section and extending over a longitudinal extent, the double-pointed needle including a first portion projecting away from the support section in a first projecting direction and terminating at a first sharpened end for puncturing a stopper in the medicine container, the double-pointed needle including a second portion projecting away from the support section in a second projecting direction and terminating at a second sharpened end for puncturing a stopper in the liquid container, the double-pointed needle possessing a lumen extending throughout the longitudinal extent of the double-pointed needle and opening to both the first sharpened end and the second sharpened end of the double-pointed needle;
a first tube-shaped section fixed to the support section and projecting away from the support section in the first projecting direction, the first tube-shaped section possessing an inner peripheral surface and the first portion of the double-pointed needle possessing an outer peripheral surface, the first tube-shaped section surrounding the first portion of the double-pointed needle so that a space exists between the outer peripheral surface of the first portion of the double-pointed needle and the inner peripheral surface of the first tube-shaped section;
a second tube-shaped section fixed to the support section and projecting away from the support section in the second projecting direction, the second tube-shaped section possessing an inner peripheral surface and the second portion of the double-pointed needle possessing an outer peripheral surface, the second tube-shaped section surrounding the second portion of the double-pointed needle so that a space exists between the outer peripheral surface of the second portion of the double-pointed needle and the inner peripheral surface of the second tube-shaped section;
the first tube-shaped section and the second tube-shaped section each possessing an outer periphery, the outer periphery of the first tube-shaped section and the second tube-shaped section being differently shaped;
the shape of the outer periphery of the first tube-shaped section permitting the first tube-shaped section to be positioned in the first port of the holder and preventing the first tube-shaped section from being positioned in the second port of the holder; and
the shape of the outer periphery of the second tube-shaped section permitting the second tube-shaped section to be positioned in the second port of the holder and preventing the second tube-shaped section from being positioned in the first port of the holder.

Abstract
A connector is configured to be connected to a syringe assembly provided with at least one syringe having an outer cylinder with a protruding tube-shaped port, and a holder which holds the syringe. The connector includes a connector main body mountable on a container containing a medical solution; a tube-shaped fitting section protruding from the upper section of the connector main body for receiving the syringe to connect the inside of the syringe and the inside of the container when the syringe port is fitted in the fitting section; and fixing means having a lock mechanism that fixes the syringe assembly to the connector main body when the syringe port is fitted in the fitting section, an operating section to release the fixed state provided by the lock mechanism, and a push-out section that pushes out the syringe assembly when the fixing releasing operation is performed.

4. A syringe assembly in combination with a connector,
the syringe assembly comprising: -
a syringe that includes a plunger slidably positioned in an outer cylinder, a tube-shaped port protruding from a leading end of the outer cylinder, and a holder fixed to the syringe, the holder including an engagement portion; the connector comprising; a connector main body configured to be mounted on a medical solution container containing a medical solution; a needle pipe projecting in a first projecting direction from the connector main body, the needle pipe possessing a sharp needle point at an end of the needle pipe remote from the connector main body, the needle pipe including a lumen opening to the sharp needle point; a tube-shaped fitting protruding from the connector main body in a second projecting direction opposite the first projecting direction, the tube-shaped fitting possessing an interior sized and shaped to receive the tube-shaped port of the syringe, the interior of the tube-shaped fitting communicating with the lumen of the needle pipe; an arm rotatably mounted on the connector main body to engage the engagement portion of the holder to fix the syringe assembly in place relative to the connector with the tube-shaped port of the syringe positioned in the tube-shaped fitting of the connector; and a holding device connected to the arm to hold the arm in engagement with the engagement portion of the holder and to permit the arm to be moved out of engagement with the engagement portion of the holder to permit the syringe assembly to be released from the connector. - View Dependent Claims (5, 6, 7, 8)
