| 摘要 |
A peripheral catheter assembly having a hollow catheter hub, a female proximal end, a distal end provided with a catheter tube, at least one infusion port located between the distal and proximal ends, a hollow needle module that includes a needle held by a male socket arranged to sealingly engage the female proximal end, and a sealing member engaged inside the catheter hub which serves for facilitating venipuncture without unintended splashing of blood. A sealing valve that includes a septum seal having a weakened portion surrounded by deflectable septum walls, and a hollow tubular extension which protrudes towards a free end from the periphery of the septum seal and extends inside the catheter hub past the infusion port towards the distal end of the catheter hub provide a self-closable sealing member which provide the physician the freedom to leave the patient when the needle module is retracted.
