Port assembly

The infusion port assembly comprises an infusion port and a non-injury puncture needle, the infusion port comprises a port base, a liquid storage cavity is formed in the port base, an injection base is fixedly arranged at the top of the liquid storage cavity, the injection base and the liquid storage cavity are coaxial, the lower surface of the injection base is sunken upwards, and the non-injury puncture needle is arranged in the injection base. The non-injury puncture needle comprises a needle tube and a bent part arranged at one end of the needle tube, and the height of the bent part is smaller than the distance between the bottom of the liquid storage cavity and the lower surface of the injection base. According to the scheme, the overall sealing performance and compression resistance of the infusion port are improved, meanwhile, it is guaranteed that the injection base cannot be hooked and scratched to generate chippings when the damage-free puncture needle is pulled out, and the safety performance of th
