Abstract: The present invention discloses a safety infusion connector, which includes a combination type inner pipe, a first resilient member, a sealing member, and a housing. The first resilient member hermetically seals an inlet of the housing. The sealing member hermetically seals an outlet of the housing. With such a double hermetic sealing structure, the safety infusion connector is capable of stopping leakage and has an excellent airtight effect. When the safety infusion connector is in use, a part of the combination type inner pipe is secured and stationary, thereby enhancing the structural stability. Furthermore, the combination type inner pipe includes: a first inner pipe having a first protruding portion, a fitting portion, and at least a first abutting portion, wherein the fitting portion is connected to the first protruding portion and the first abutting portion, a free end of the first protruding portion is provided with at least a first through hole, and a first passage is disposed inside the first protruding portion and is in communication with the first through hole; and a second inner pipe having a second protruding portion, a trunk portion, and at least a second abutting portion, wherein the trunk portion is connected to the second protruding portion and the second abutting portion, a free end of the second protruding portion is provided with at least a second through hole, a second passage is disposed inside the second protruding portion and the trunk portion and is in communication with the second through hole, and a flange protruding outward is disposed at the free end of the second abutting portion. The fitting portion and the trunk portion fit to each other. The first abutting portion and the second abutting portion are arranged alternately. The free end of the first protruding portion and the free end of the second protruding portion face two opposite directions. The first passage is in communication with the second passage. The housing has a peripheral wall and a first end wall and a second end wall which close two ends of the peripheral wall respectively. The peripheral wall, the first end wall, and the second end wall jointly define a first receiving space. Each of the first end wall and the second end wall has an opening with a rim extending outward to form a first circumferential wall and a second circumferential wall. The first circumferential wall defines a first channel and the second circumferential wall defines a second channel. The first resilient member has a head portion, a body portion, and a fixing portion. The head portion extends laterally from one side of the body portion to form a closed end. The other side of the body portion extends to form an opening end. A second receiving space is defined inside the body portion and is in communication with the opening end. A positioning notch is disposed on an inner wall surface of the body portion. The fixing portion is connected to the opening end and fixed to the housing.
