SYRINGE BARREL WITH PUNCTURE FUNCTION, SYRINGE WITH PUNCTURE FUNCTION, AND PREFILLED SYRINGE WITH PUNCTURE FUNCTION |
摘要 |
A syringe barrel includes a cylindrical main body portion configured to allow liquid-tight sliding of a gasket; and a hollow distal end portion configured to extend distally from the cylindrical main body portion. The distal end portion includes: a hollow small-diameter distal end portion having a puncture end portion configured to be inserted into a puncturable portion of a medical device having a female luer taper; and a large-diameter portion having a diameter larger than a diameter of the small-diameter distal end portion, an outer surface of the large-diameter portion being tapered such that the outer diameter of the large-diameter portion increases from a distal end to a proximal end thereof. The large-diameter portion is configured to connect to a connection portion of the medical device. The small-diameter distal end portion is housed in the connection portion upon connection of the large-diameter portion to the connection portion. |
