Title:
多液系物質の手動分配シリンジ
Document Type and Number:
Japanese Patent JP4145490
Kind Code:
B2
Abstract:
A syringe (10) includes a tube (12) defining a chamber (16) with a dispensing opening (18). A plunger (20) is slidably mounted in the tube and is initially positioned at the end (24) of the chamber opposite the dispensing opening. A dasher (26) having an opening (34) is positioned within the chamber at an intermediate point. A cylindrical barrier (40) is detachably secured to the dasher (26). Thus, with the barrier secured to the dasher, the barrier and dasher sealingly engages the tube dividing it into two subchambers (44, 46). An elongated rod (52) extends through openings (54, 56) in the plunger and the barrier and is secured to the dasher. Rotation of the rod detaches the barrier from the dasher establishing communication between the subchambers. A locking sleeve (62) frictionally secures the rod and the plunger together when the rod is moved to a retracted position (FIG. 4). Furthermore, optionally the rod is hollow (FIG. 9) and defines a third subchamber (80) containing a third liquid.
