Abstract
The invention relates to an anesthesia machine respiratory system, including a driving gas isolation means, a driving gas control system and a circulatory and respiratory system; the driving gas control system and the circulatory and respiratory system are both connected with the driving gas isolation means; and the driving gas isolation means comprises a means body in which at least two gas channels are disposed in parallel and having an elongated structure. The driving gas isolation means in the anesthesia machine respiratory system achieves non-physical isolation between a driving gas and a mixed gas carrying a large amount of narcotic drugs through the elongated and parallel air channels, wherein no arrangement of an elastic member such as a foldable bag enables the driving gas isolation means to control the pressure and flow more accurately. The air channels are of a parallel structure, has a length of 1-4 meters, and are conducive to reducing the air resistance when a patient is breathing and improving the comfort of the patient. Further provided is an anesthesia machine using the anesthesia machine respiratory system.
Description
Technical field
The present invention relates to field of medical device, particularly relate to a kind of anesthetic machine and anesthetic machine respiratory system thereof.
Background technology
The respiratory system of anesthetic machine is divided into non-respiratory system again and respiratory system again.The anesthetic machine of respiratory system is adopted to be most widely used again.Be different from non-respiratory system again, in the anesthetic machine of respiratory system again, the gas that patient breathes out can be recycled.Concrete, usually adopt bellows structure to realize the isolation of driving gas and patient's breath, to reduce the loss of the anaesthetic that patient breathes out.During expiration, the gas that live gas and patient breathe out enters the folding capsule in bellows in the lump, and during air-breathing, driving gas enters in bellows, drives the gas in folding capsule again to enter in the lung of patient.
Traditional anesthetic machine, its driving gas spacer assembly adopts bellows structure to realize the isolation of driving gas and patient's breath mostly, and the gas pressure in patient's lung and flow all act on the realization of folding capsule by controlling driving gas.But because folding capsule material softness has certain elasticity, be difficult to when ventilation is less accurately control, and there is a small end expiratory positive pressure in relief valve, especially has a serious impact neonatal ventilation, may cause hypoventilation.
