Perfusion device, anesthetic vaporizer, and anesthetic machine

An anesthetic machine comprising

• an anesthetic vaporizer, the anesthetic vaporizer comprising:
• a vaporizer body provided with a feed port and a tank, and the tank communicating with an outside via the feed port;
• a perfusion device comprising a mounting assembly, an ejector rod assembly and a valve core assembly, the valve core assembly provided with a liquid inlet channel, the mounting assembly comprising a mounting seat mounted on the feed port, the mounting seat comprising a hollow structure having openings at two opposite ends of the hollow structure, the valve core assembly being movably mounted on one of the openings at one of the two opposite ends of the hollow structure facing the tank, the ejector rod assembly being movably mounted on another one of the openings at another one of the two opposite ends of the hollow structure and forming a sealed structure with the mounting assembly, the ejector rod assembly being configured to drive the valve core assembly to move toward the tank under an external force, and the liquid inlet channel communicating with the hollow structure,
• wherein the mounting assembly further comprises a liquid injection seat configured to receive and engage a mouth of an anesthetic bottle, and the external force is applied to the ejector rod assembly upon engagement of the mouth of the anesthetic bottle with the liquid injection seat.

A perfusion device for use in an anesthetic vaporizer with a feed port and a tank, comprising:
