Beauty manufacturers parsing the working principle and advantages of anesthesia ventilator
Hemp drunk time transformation characteristics of breathing machine has the typical, powered by motor, compressed gas.And the recent foreign production of anesthesia machine, with breathing machine electric control system, do not drive, can in the case of expired, ventilation by atmospheric supplement, ensure patient safety.Such as Siemens SC3000 and so on.Typical breathing machine, bellows fixed in anesthesia breathing back on the road, in a clean plastic indoor, it contains anesthetic gasses.During the breath, driving gas transporting into indoor, compression bellows.Bellows O2 is commonly used for driving gas, O2 concentration is easy to improve.During the breath, drive air into the indoor, passive patients inhale, bellows is full again.Breathing machine also can appear dangerous, the common risk factors are: anesthesia loop and patients not connected or connection errors;Delivery pressure is too high;Breathing machine exhaust valve failure;Driving mechanism of failure.Loop anesthesia loop between anesthesia machine, common gas exports, function of anesthesia loop for the anesthetic gas and oxygen to the patient, and CO2 discharge.Loop system including fresh gas inlet, inspiratory and expiratory single live debate, inspiratory and expiratory rib tube, Y type connecting tube, adjustable exhaust live debate, storage airbag and CO2 absorber, etc.The loop has both advantages and disadvantages.Advantage: save the fresh gas;Wet process improvement;Save the heat;Pollution to reduce the operating room.Disadvantages: complex design;CO2 absorber failure, can cause severe fault;Loop system through chemical reaction absorb CO2, water and heat, CO2 absorber indicator, absorbent fails, indicator color change.
