Catheter adapter system for proximal tailorable catheter

Embodiments disclosed herein relate to a connection system that includes a port, a catheter, a catheter lock, and an adapter. An adapter may be coupled with the proximal end of the catheter, and a catheter lock may cooperate with the adapter to secure the catheter to the port in a liquid-tight engagement. One of the catheter lock and the adapter threadably engages the port and employs mechanical advantages to radially compress the catheter and ensure a fluid-tight seal. The system may also include an insertion tool configured to assist in securing the adapter to the catheter or securing the adapter or catheter lock to the port. The adapter may be provided or coupled to the catheter lock as a separate structure. The engagement of the adapter with the catheter may be signaled by auditory rattling. Optionally, the adapter may include a skirt configured to compress the conduit onto the adapter rod. 本文所公开的实施方案涉及一种连接系统，该连接系统包括端口、导管、导管锁和适配器。适配器可与导管的近端联接，并且导管锁可与适配器协作，以将导管以液密接合的方式固定至端口。导管锁和适配器中的一者可螺纹地接合端口，并且采用机械优势来径向压
