Abstract: Disclosed is an anesthetic evaporator, including a housing, a drug reservoir, and a cover movably connected to the housing. The drug reservoir is provided with a drug adding barrel arranged corresponding to the cover, and further includes a mechanical pressure relief assembly and a linkage mechanism. The mechanical pressure relief assembly is connected to the drug reservoir. The mechanical pressure relief assembly has a first state in which the pressure within the drug reservoir is maintained and a second state in which the pressure within the drug reservoir is released. When adding a drug, the operation action on the anesthetic evaporator drives the linkage mechanism, and the linkage mechanism drives the mechanical pressure relief assembly to switch same from the first state to the second state.

Abstract: An anesthetic evaporator is provided. The anesthetic evaporator includes a housing, an anesthetic agent storage tank, a cover, a mechanical pressure relief assembly connected with the anesthetic agent storage tank, and a linkage mechanism. The mechanical pressure relief assembly is provided with a first state in which a pressure within the anesthetic agent storage tank is maintained and a second state in which a pressure within the anesthetic agent storage tank is released. When adding an anesthetic agent, an operation action on the anesthetic evaporator drives the linkage mechanism, and the linkage mechanism drives the mechanical pressure relief assembly to be switched from the first state to the second state.

Abstract: An anesthetic evaporator locking structure for detachably connecting an anesthetic evaporator to an anesthesia main machine is disclosed. The anesthetic evaporator includes a main body and a securing member provided on the main body. The anesthesia main machine includes a driving element and a mating member provided on the anesthesia main machine. The securing member and the mating member mate with each other to form a primary locking mechanism, and when the anesthetic evaporator is in an activated state, the driving element limits the primary locking mechanism to realize secondary locking. The anesthetic evaporator further includes a handle provided on the main body and an unlocking device provided on the handle, and the unlocking device is used for unlocking the primary locking mechanism. The anesthetic evaporator locking structure can realize the double locking and has relatively high safety, and both the locking and unlocking processes can be operated by one hand, which is convenient and quick.

Abstract: This disclosure provides a perfusion device, an anesthetic vaporizer, and an anesthetic machine. The anesthetic vaporizer includes a vaporizer body and the perfusion device. A feed port and a tank are provided in the vaporizer body. The perfusion device includes a mounting assembly, an ejector rod assembly, and a valve core assembly that is provided with a liquid inlet channel. The mounting assembly includes a mounting seat that is mounted on the feed port and provided with a hollow structure having an opening at both ends. The valve core assembly is movably mounted on one opening of the hollow structure, and the ejector rod assembly is movably mounted on the other opening of the hollow structure and forms a sealed structure with the mounting assembly. The ejector rod assembly may drive the valve core assembly to move toward the tank, and the liquid inlet channel communicates with the hollow structure.

Abstract: An electric inflator for connecting and inflating an inflatable device includes a shell, a drive motor configured on the axis of the shell, at least one air bag is configured in the shell and around the drive motor, an air outlet of the air bag connected to an inflatable device, and a pressing mechanism connected to an output portion of the drive motor. The air bag is pressed by the pressing mechanism driven by the drive motor for supplying air to the inflatable device. An inner space of the shell can be fully utilized thereby the size of the electric inflator is smaller than before. At the same time, an inner cavity of the air bag can be bigger than before to improve inflating efficiency, which increases portability and practicability of the electric inflator and the inflatable device equipped with the electric inflator.
