摘要： A low-profile access port for subcutaneous implantation within the body of a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable a catheter-bearing needle to access the port without difficulty. In addition, the access port includes a valve/seal assembly to permit pressurized fluid injection through the port while preventing backflow. In one embodiment, therefore, a low- profile access port comprises a body including a conduit with an inlet port at a proximal end thereof, and a receiving cup. The receiving cup is concavely shaped to direct a catheter- bearing needle into the conduit via the inlet port. The receiving cup is oriented substantially toward a skin surface when subcutaneously implanted within the patient to ease needle impingement thereon. A valve/seal assembly disposed in the conduit enables passage of the catheter therethrough while preventing fluid backflow.
摘要翻译：公开了一种用于皮下植入患者体内的小型进入端口。进入端口包括接收杯，该接收杯提供相对较大的皮下目标以使导管承载针能够毫无困难地进入端口。另外，进入端口包括阀门/密封组件以允许加压流体通过端口注入，同时防止回流。因此，在一个实施例中，低轮廓进入端口包括主体，该主体包括在其近端处具有入口端口的导管以及接收杯。容纳杯呈凹形，以通过入口将带有导管的针头引导到导管中。当皮下植入患者体内时，接收杯基本上朝向皮肤表面取向，以减轻其上的针撞击。布置在导管中的阀/密封组件能够使导管通过，同时防止流体回流。
