Principle of anesthetic machine
Anesthesia gas supply in addition to N2O is through the flow of control directly and O2 mixed for patient breathing (generally laugh - oxygen linkage device Protection), the other by evaporating pot Sheng anesthetics volatile liquid output after the anesthetic steam, according to a certain concentration of supply patients breathe in, so the evaporation tank.
Can be described as the core component of the anesthesia machine, related to the depth of anesthesia and the patient's safety.
The most simple evaporation tank is sucked into the anesthetic container space above by a certain amount of O2, air or N2O+O2 mixture dilution (in full Gas), a small portion of the gas flow through the valve into the evaporating chamber, and takes away saturated vapor (carrier gas), the dilution gas flow and the air current in the output
In the confluence of mixed into airflow containing a certain percentage concentration of anesthetic vapor, enters the breathing loop for the patient in.
The gas flows through the evaporation chamber and the way it is used by the anesthetic vapor:
Whisk of airflow over type (flow-over, also known as the air plenum): carrier gas from the anaesthetic level whisk away anesthetic vapor molecules.
Air flow into the evaporation chamber, indoor pressure. Most anesthesia machine used in the evaporator are this type.
The air suction type (Draw-over): with the help of patients with pneumatic suction anesthetic vapor, thus the negative pressure evaporation chamber. airflow
Through the resistance must be very low.
The bubble type (Bubble through): the carrier gas through the liquid anesthetic into numerous small bubbles, thereby increasing the evaporation area.
The drop into type (dropper): the anesthesia medicine liquid control can drop into (or micro syringe injection) after evaporation in a breathing circuit for the patient
Breathe in.
Both the type: air can be brushed surface, also with liquid bubble penetration function.
For the output constant correct anesthetic concentration, the modern anesthesia evaporator are also temperature, pressure compensation device.
