Anesthetic gas-inducing device for rodent to allow gradually from a conscious state to a anesthetized state, comprises isolation cell with pin connection sockets, induction cylinder, anesthetic gas generator, mobile and principal bodies

摘要

The induction of anesthetic gas and the cell are auxiliary equipment of the generator and connected to sockets of coaxial duct which allows independent circulation of the halogenated gases and to a system of extraction of polluted gases. The independent circulation of the gases is prohibited if the sockets are disconnected. The induction of anesthetic gas has mobile parts comprising moving and fixed parts integrated into frame. The cylinder is removed from the moving part by dismantling. The fixed part is provided with central and peripheral channels for allowing free circulation of halogenated and residual halogenated gases. The moving part is assembled on the principal body by pivot with 90[deg] rotation. The induction of gases is operational during the passage of the induction cylinder from the horizontal to vertical position. The mobile body is equipped with a cam and a valve for controlling the opening or the closing of the passage of gases. The isolation cell has moving parts adapted to the principal body, which is equipped with an adjustment wheel supported by fixed frame, which can be removed in order to, be transferred to a unit of acquisition of medical imagery data. The removable parts and principal body are connected with drillings and thermally insulated double circuit. The cell is provided with a cone and a channel equipped with stopper. The maintenance tunnel is equipped with another channel for the passage of gases delivered at the cone outlet and inclined along its longitudinal axis. The wheel adjusts the minimum and maximum extraction of gases by the obstruction of air inlet. The outlets of the drillings are connected to the extraction duct of cold gas and heating duct used for the reintroduction of heated gases into the transparent external chamber double circuit.
