<p>A method and apparatus for injecting radiographic dye during angiography, are provided. A deformable holding chamber (14) is interposed between a contrast dye bottle (12) and a syringe manifold (16). A one-way valve (36) and an integral disconnect/flow stop (28) are connected between the bottle (12) and the holding chamber (14). A vent (54) is provided in the holding chamber (14), with a second one-way valve (58). Squeezing and releasing the deformable chamber (14) fills the chamber (14) from the bottle (12). The holding chamber (14) contains a floating baffle (52) which acts as a shutoff valve by plugging the chamber outlet if the chamber (14) becomes empty. The syringe (50) is used to withdraw dye from the holding chamber (14). If dye remains in the bottle (12) after performance of the procedure, the disconnect/flow stop fitting (28) can be disconnected, and the dye can be saved.</p> |
