Medical connector

摘要

A first male member (110) and a tubular portion (30) are in communication via first to third holes (21 to 23). A liquid channel (211) and a gas channel (212) of the second male member (210) are in communication with the tubular portion. First to third channels (41 to 43) are formed in a stopcock (40). The stopcock can switch between a first rotation position at which the first channel puts the first hole and a syringe connection portion (32) of the tubular portion in communication, and a second rotation position at which the first channel puts the liquid channel and the syringe connection portion in communication. When the stopcock is at the second rotation position, the second hole and the gas channel are in communication via the second channel, and the first male member and an inner cavity (45) of the stopcock are in communication via the third hole and the third channel. A first hydrophobic filter (50a) is provided in the channel that connects the first male member and the gas channel when the stopcock is at the second rotation position, and a second hydrophobic filter (50b) is provided in the channel that connects the first male member and the air supplying member (410) that is connected to the stopcock when the stopcock is at the second rotation position.

主权项

1. A medical connector comprising:
a first connector including a bar-shaped first male member capable of being in communication with a first container; a second connector including a bar-shaped second male member capable of being in communication with a second container; a tubular portion including a syringe connection portion that is configured to be in communication with a syringe; and a stopcock that is inserted into the tubular portion and is capable of rotation relative to the tubular portion, wherein a first hole, a second hole, and a third hole that put the first male member and the tubular portion in communication are formed in the tubular portion, a liquid channel and a gas channel formed in the second male member are in communication with the tubular portion, a first channel, a second channel, and a third channel are formed in the stopcock, by rotating the stopcock, the position of the stopcock can be switched to a first rotation position at which the first channel puts the first hole and the syringe connection portion in communication, and a second rotation position at which the first channel puts the liquid channel and the syringe connection portion in communication, when the stopcock is at the second rotation position, the second hole and the gas channel of the second male member are in communication via the second channel, a first hydrophobic filter that allows passage of a gas and does not allow passage of a liquid is provided in a channel that connects the first male member and the gas channel and is formed when the stopcock is at the second rotation position, when the stopcock is at the second rotation position, the first male member and an inner cavity of the stopcock are in communication via the third hole and the third channel, an air supplying member capable of supplying a gas to the inner cavity of the stopcock is connected to the stopcock, and a second hydrophobic filter that allows passage of a gas and does not allow passage of a liquid is provided in a channel that connects the air supplying member and the first male member and is formed when the stopcock is at the second rotation position.
