X-bar stopcock device for pulmonary artery catheterization

Abstract

A unified X-bar stopcock, including a bidirectional stopcock having a first port, second port, third port, and fourth port; and a three-way stopcock having a fifth port, sixth port, and seventh port. The bidirectional stopcock is fluidly coupled to the three-way stopcock via the first port and the fifth port. A method of using the X-bar stopcock includes providing a Swan-Ganz catheter, an X-bar stopcock, a transducer, a monitor, and at least one bag of saline. The method includes connecting the X-bar stopcock to at least two lumens of the Swan-Ganz catheter. The method additionally includes connecting at least one port of the X-bar stopcock to the transducer connected to the monitor, connecting at least one port of the X-bar stopcock to the bag of saline, and connecting the transducer to the bag of saline. The unified X-bar stopcock may also include a protective case.
