4.4 Flow meter

4.4.1Function

Flowmeter with flow control valve which can control and indication of the supply of the patient's common gas (fresh gas) flow.O2,N2O Proportional control unit can guarantee concentration  of O₂output≥25 %.
 

4.4.2 Construe

 

Model	Construe
LX-15	4 tubes rotameter. 2 tubes of Oxygen, 2 tubes of N2O, consist of thick and thin tubes. Thin tube for small scale; Thick tube for large scale. Total scale is 15L
LX-15V	5 tubes rotameter. 2 tubes of Oxygen, 2 tubes of N2O, 1 for air. Consists of thick and thin tubes. Thin tube for small scale; Thick tube for large scale. Air tube is thick only. Total scale is 15L
LX-15	6 tubes rotameter. 2 tubes of Oxygen, 2 tubes of N2O, 2 tubes for Air. Consists of thick and thin tubes. Thin tube for small scale; Thick tube for large scale. Total scale is 15L

1. Flowmeter is a rota type with O₂,N₂O,Air. There are thick and thin tubes over 2 tubes flowmeter.
2. Flowmeter has a flow control valve, controlling the total portion of the mixed gas of O₂,N₂O,Air. Flow control valve can be adjusted with anti-clockwise to increase the flow rate, alternatively clockwise to reduce.
3. There is proportional control device between O2 and N2O to ensure the O2 concentration in the mixed gas is no less than 25%. N2O will be shut down once O2 is closed.
4. The structure of flowmeter as below:(for example LX-15V)

 

4.4.3 Accuracy

The accuracy of the full scale of 10% or 300 mL/min (whichever is larger) to full scale is between and 10% of the indicated value.
Below the full scale of 10% or 300 mL/min (whichever is the large value) of the accuracy of 4
 

1. The flow meter is equipped with flow control valve, which controls and indicates the flow of common gas (fresh gas) supplied to patient.
2. Flow control valve counter-clockwise to increase the flow, clockwise to reduce flow.
3. O₂, N₂O proportion control device can ensure concentration of the output O₂ is≥25 %.When O2 closed, N2O automatically shut down.
4. O₂ flush flow 25 L/min~ 75 L/min  

 

4.5O₂ flush button

O₂ flush button provide high-flow oxygen to the anesthesia system by the ACGO gas inlet:
 

1. Press the button to input high-flow oxygen;
2. Release the button to stop the gas flow.
