Title:

ANESTHETIC EVAPORATOR AND ANESTHESIA MACHINE

Document Type and Number:

WIPO Patent Application WO/2019/075753

Kind Code:

A1

Abstract:

Disclosed is an anesthetic evaporator, comprising a housing (10), a drug reservoir (30), and a cover (20) movably connected to the housing (10), wherein the drug reservoir (30) is provided with a drug adding barrel (31) arranged corresponding to the cover (20), and further comprising a mechanical pressure relief assembly (40) and a linkage mechanism (50), wherein the mechanical pressure relief assembly (40) is connected to the drug reservoir (30); the mechanical pressure relief assembly (40) has a first state in which the pressure within the drug reservoir (30) is maintained and a second state in which the pressure within the drug reservoir (30) is released; when adding a drug, the operation action on the anesthetic evaporator drives the linkage mechanism (50), and the linkage mechanism (50) drives the mechanical pressure relief assembly (40) to switch same from the first state to the second state. The pressure of the anesthetic evaporator can be mechanically released, so that greater safety and reliability are realized.
