The lifting shielding member has two use states, such as Figure 8 As shown, during the unfolding operation, the lifting card cover is pulled to move downward, so that several groups of telescopic covers are unfolded downward, so that several groups of telescopic covers are sleeved on the outside of the main cabinet and the evaporator, and play an electromagnetic shielding role for the main cabinet and the evaporator. When the lifting shielding part is closed, the lifting card cover is pulled upward, so that several groups of telescopic covers are sleeved on each other, so that the lifting card cover is docked at the bottom of the sealing top cover.

The display screen adopts a lifting structure design. When the anesthesia machine is used in the magnetic resonance room, the display screen can be driven up and down by the driving seat, so that the display screen can be hidden and stored conveniently. The first driving wheel and the rack are meshed with each other, and the user drives the first driving wheel with the motor, so that the first driving wheel drives the display screen up and down by the rack, and the setting of the two sets of guide wheels plays a sliding limit role on the side of the display screen when it moves, so that the display screen is hidden and stored in the shielding cover.

The setting of the wire guide can assist in conveying the connecting wire when the display screen moves up and down, so that the connecting wire follows the display screen to make corresponding position adjustments to avoid bending of the connecting wire. The connecting wire passes through the wire guide so that the second driving wheel and the two sets of elastic clamping wheels are attached to the outer surfaces on both sides of the connecting wire. The two sets of elastic clamping wheels can be adjusted arbitrarily according to the thickness changes of the connecting wire by using the setting of the elastic clamping seat. The user uses the motor to drive the second driving wheel to rotate, so that the second driving wheel drives the connecting wire to move up and down, so that the connecting wire can be adjusted arbitrarily according to the position of the display screen to avoid bending of the connecting wire. The top plate is made elastic by using a spring, and the elastic clamping seat and the wire guide are elastically connected through the top plate, so that the two sets of elastic clamping wheels at one end of the elastic clamping seat have an elastic pressing structure, so that the elastic clamping wheel can be tightly attached to the surface of the connecting wire, thereby improving its use effect.

[0024] 3. By setting a lifting shielding part, when the magnetically compatible anesthesia machine is used, the use effect of the shielding cover is improved, and the lower part of the shielding cover has a lifting auxiliary shielding structure, thereby completing the overall shielding of the anesthesia machine and reducing electromagnetic interference;

The lifting shielding member has two use states, such as Figure 8 As shown, during the unfolding operation, the lifting card cover is pulled to move downward, so that several groups of telescopic covers are unfolded downward, so that several groups of telescopic covers are sleeved on the outside of the main cabinet and the evaporator, and the main cabinet and the evaporator are electromagnetically shielded, so that the anesthesia machine can be used in the magnetic resonance room. When the lifting shielding component is closed, the lifting card cover is pulled upward so that several groups of telescopic covers are sleeved on each other, so that the lifting card cover is docked at the bottom of the sealing top cover, so that the anesthesia machine can be used in a normal environment. When the lifting card cover is unfolded downward, the docking card strip and the card slot of the sealing base are docked with each other, thereby improving the overall sealing of the lifting shielding component.

[0048] When in use, currently, most surgeries are performed in ordinary environments, and ordinary anesthesia machines can be used. However, surgeries performed in magnetic resonance environments generally use very long gas pipelines to introduce the gas generated by the anesthesia machine into the magnetic resonance room. The operation is not flexible enough, and the anesthesia effect is not ideal. Traditional anesthesia machines are affected by electromagnetic interference and cannot be used in magnetic resonance environments.
