医用连接器及其使用方法
摘要：
在此公开的一些实施例涉及一种医用连接器，该医用连接器具有回流阻挡模块，用于在发生回流促导事件时防止流体被吸入连接器。在一些实施例中，所述回流阻挡模块可包括可变容积室，用于在发生回应回流促导事件时改变容积，以及用于阻挡回流的止回阀。在一些实施例中，所述医用连接器可包括流体分流器，用于将流经医用连接器的流体导入可变容积室，以防止流体滞留在其中。在一些实施例中，所述医用连接器包括主体构件、基座构件、密封构件、支撑构件和阀构件。
摘要（英）：

Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.
