Since 1846, when Lanning first applied ether anesthesia, inhalation anesthesia has been improving. The development of modern pharmacology, the progress of science and technology, especially the application of computer technology, have greatly improved the level of modern inhalation anesthesia. Inhalation anesthesia is easy to control, safe and effective. is the first choice for the current hospital operation.
The so-called anesthesia is to instruct the organism to temporarily lose consciousness all or partly, in order to carry on the surgical treatment method. There are various methods of anesthesia, such as anesthesia, injection anesthesia and inhalation anesthesia. At present, the method of using general anesthesia in hospitals is still mainly inhalation anesthesia. Anesthesia machine is the use of inhalation anesthesia method for general anesthesia equipment.
Modern anesthesia machine is towards the intelligent, integrated system development, the components of the combination of coordination, flexible, reliable, compact structure, reasonable use of clear and friendly interface, easy to operate and fast. Electronic control gas transmission system, built-in electronic control anesthesia respirator, integrated breathing circuit, the integrated gas Monitoring system, high and low flow of anesthesia is the best combination of modern anesthesia machine. The new generation of anesthesia workstations will be expanded into the entire medical system, with hospital equipment to network, communicate, define, adjust the anesthesia process and records, evaluate the anesthetic effect, improve patient care quality, to create a good working atmosphere for clinicians. The modern anesthesia machine according to the structure principle can be divided into: Gas supply transportation system, anesthetic gas volatile tank, breathing circuit, anesthesia breathing machine, safety monitoring system and residual gas clearance system.
