CONNECTOR FOR DOUBLE MIXING SYRINGE, LONG NOZZLE FOR DOUBLE MIXING SYRINGE AND DOUBLE MIXING SYRINGE

Document Type and Number:

WIPO Patent Application WO/2019/052510

Kind Code:

A1

Abstract:

Disclosed is a medical instrument, and in particular, a connector (2) for a double mixing syringe, a long nozzle (6) for a double mixing syringe, and a double mixing syringe comprising the connector (2) and/or the long nozzle (6). A connector outlet joint (22) of the connector (2) for the double mixing syringe forms an outlet stepped structure, and a long nozzle inlet portion (631) of the long nozzle (6) for the double mixing syringe forms an inlet stepped structure corresponding to the outlet stepped structure, such that the long nozzle inlet portion (631) of the long nozzle (6) can be assembled with the connector outlet joint (22) of the connector (2) in a sealed manner and receive a liquid from the connector (2), thereby the connector (2) is adaptively connected to the long nozzle (6); and also, the connector (2) for the double mixing syringe can also be adaptively connected to a short nozzle (1). Thereby, the connector (2) for the double mixing syringe can be used in both spray-type and endoscope-type usage modes, and also enables the connector (2) to be accurately butt-jointed with the long nozzle (6) in a simple manner.
