摘要： A pressure activated valve for a three-way connection between a catheter, an injector and a pressure transducer is disclosed. The valve includes a body that has an inlet for connection to an injector, an outlet for connection to a catheter and a secondary connection for connection to a pressure transducer. The body also includes a seal seat disposed between the secondary connection in both the inlet and the outlet. The body is flexibly connected to a plug seal. The plug seal is disposed between the seal seat in both the inlet and the outlet. The plug seal is movable between an open position spaced apart from the seal seat and biased towards the inlet and the outlet and a closed position against the seal seat thereby isolating the secondary connection from both the inlet and the outlet.

摘要： A fluid injection system is disclosed The system is adapted to employ first and second injectors which may sequentially, or simultaneously, inject first and second fluids into a patient via a catheter. The first and second injectors may be power actuated. The actuation of the injectors may be controlled via a controller of the system. The user may be provided with an operator interface module to enable the control of the system to be affected during operation. A separate waste line may be provided to drain the system effectively and efficiently. A pressure sensor may be provided proximate the catheter to reduce pressure signal wave dampening and fluid waste.
摘要翻译： 公开了一种流体注射系统。该系统适于采用可以依次或同时地将第一和第二流体经由导管注射到患者体内的第一和第二注射器。 第一和第二注射器可以被动力驱动。 注射器的致动可以通过系统的控制器来控制。 用户可以设置有操作者接口模块，以使得在操作期间能够对系统的控制进行影响。 可以提供单独的废液管线来有效地排出系统。 可以在导管附近设置压力传感器以减少压力信号波浪衰减和流体浪费。
