Ordinary domestic anesthesia machine cost about RMB100,000,if accompanied by a monitor anesthesia machine will probably cost around RMB200,000,general type anesthesia machines which is imported will more than RMB200,000-300,000 and above.The type of anesthesia machines are classified according to high and low flow,technicians from MSL Guangzhou provide some professional tips to know about the type of anesthesia machines,as below:
anesthesia machine classified according to structure and function,can be divided into the following categories:
1.All-in-one type:multi-function,complex structure,complete functions and also has an electronic or computer-controlled management system,monitoring equipment,alarm systems,some of anesthetic machines have automatic recording system.
2.Universal type:The structure and function compared with All-in-one type of anesthesia machines will be relatively simple but it still has the basic and important structures and components such as nitrous oxide,automatic cut-off device and a security system.The operational aspects also relatively simple such as assembled or unassembled simple ventilator of structure and function.
3.Portable anesthetic:with anesthetic machine's basic functions and simple structure,Light,Move Flexible and convenient to carry anywhere.The working principle is:after patients completed the induction of anesthesia,anesthesia machines closed the air masks or tracheal tube connections.When inhale,the anesthetic gas mixture with open suction valve into the body;when exhale,exhale valve opens and suction valve closed from the exhaled gas.When assisted or controlled breathing is used,the available folding bellows.Breathe in under pressure,pulled up on the exhale,ensure there is sufficient ventilation.According to the actual need,adjust the ether-switch in order to maintain a stable level of anesthesia.
4.High-flow type:This type of machines can provide the minimum flow of nitrous oxide are mostly above the 0.5L/min,so it is for high-flow anesthesia only.
5.Low-flow type:This type of oxygen and nitrous oxide anesthesia machine can provide estimated minimum flow rate up to 0.02L/min or 0.03L/mi,so this type of low flow anesthesia machine also can for low-flow and high-flow anesthesia.
Anesthesia machine classified according to age,it can be divided into the following categories:5.anesthesia machines for adults;
6.Pediatric anesthesia machines;
7.Pediatric and adults type anesthesia machines: this type of anesthesia machine equipped with a loop and a pediatric ventilator bellows.
8. Adult pediatric anesthesia machines use either: namely adult anesthesia machine with a pediatric circuit and pediatric ventilator bellows.
Principles of other common types for anesthesia machines
9.Air-type: The semi-open anesthetic apparatus.It mainly has liquid tank,ether switch,folding bellows and suck and breath of unidirectional and the corrugated tube.The device is portable application and direct access to air and oxygen as the carrier gas,capable of breathing and breath control,meeting various kinds of surgery.
10.Direct-flow type with high pressure oxygen,regulator,flow meter and anesthesia liquid evaporator components.The instruments can only provide breathing gas oxygen and regulated concentrations of anesthetics,there must be other device series with the output position to the anesthesia.
11.Cycle closed type: The device is low-flow anesthetic gas mixture,the air escape valve (door) one-way activity supply of patients.Exhaled gases exhale valve into the CO2 absorber for reuse.Its structure is mainly composed of nitrous oxide and oxygen installations,gas flow,CO2 absorber evaporator; unidirectional,breath pipe,storage components such as air bags,air escape valve.
