Abstract
The invention provides an anesthesia machine comprising a driving gas branched path, a fresh gas branched path, and a breathing circuit. The fresh gas branched path delivers fresh gas having anesthetic into the breathing circuit. The driving gas branched path drives fresh gas from the breathing circuit to a patient. The driving gas branched path comprises a fan assembly, which comprises a housing, a fan, and a heat-dissipating member. The fan is disposed in a first inner chamber, and drives air into the first inner chamber. The heat-dissipating member conducts to the housing the heat generated by the motor.
