Application of Portable Anesthesia Machine

Application of Portable Anesthesia Machine

Portable anesthesia machines are mainly used for outdoor operations, such as field operations, disaster relief, and emergency surgeries. Due to the different environments used, portable anesthesia machines and conventional anesthesia machines are more prominent and convenient to carry. Based on this principle, they are further expanded towards intelligent, integrated, and multifunctional aspects.

The structure required for a portable anesthesia machine includes an anesthesia evaporator, respiratory support system, and respiratory circuit. As one of the core components of an anesthesia machine, the volatilization tank must ensure that the anesthesia gas has an accurate concentration of volatilization when releasing anesthesia, and can control the depth of anesthesia. The respiratory circuit provides respiratory support to patients under anesthesia, including oxygen mixing of anesthesia gas, exchange of exhaled gas and anesthesia gas, absorption of exhaled carbon dioxide gas, and switching between manual machine control states. In summary, the basic composition of a portable Anesthesia Machine is similar to that of a regular anesthesia machine, but the design is more focused on small and portable size.

Portable anesthesia machines in China were initially developed, with simple structure, bulky volume, and inconvenient portability. There is an evaporator but there is no automatic breathing support system in computer-controlled mode. With the development of technology, truly portable anesthesia machines have been developed for various occasions.

What are the characteristics of portable anesthesia machines: lightweight and portable. Functional units tend to be small, integrated, and modular. 

Low power consumption: In the case of limited power supply and origin, limited resources should be utilized to the maximum extent possible. 

Sturdy structure: Used in various harsh environments, it should have characteristics such as dustproof and moisture-proof. Another thing is that not all users of portable anesthesia machines are professional anesthesiologists, so it is best to design an "emergency automatic control" working mode for emergency use by personnel in emergency situations and those who do not have knowledge of operating ventilators.
