Mindray Ventilator Machine Parts EV20 O2 Oxygen Proportional Valve with Cable for Hospital Medical Device

Description

Designed to maintain accurate and repeatable flow in a wide variety of media, the Mindray EV20 valve can be controlled via DC current or pulse width modulation with closed-loop feedback to provide optimal system performance.

The oxygen proportional valve of the ventilator, referred to as OPV or oxygen proportional valve, is one of the core components in the ventilator's air circuit system. Its core function is to accurately control the oxygen concentration (FiO₂) in the inhaled gas to ensure that the gas inhaled by the patient meets the oxygen concentration requirements set by the medical setting (such as 21%~100% adjustable).

Features:

1. Function: According to the set value (such as 40%, 60%, etc.), real-time mixing of air (containing 21% O₂) and pure oxygen (100% O₂) outputs gas with target oxygen concentration, and quickly responds to flow changes during the patient's inhalation phase to avoid oxygen concentration fluctuations.

2. Working principle: The flow ratio of air and oxygen is adjusted by a solenoid valve or a piezoelectric valve. The flow ratio of air and oxygen is adjusted by a solenoid valve or a piezoelectric valve.

3. The valve action time is in milliseconds, which adapts to the high-frequency ventilation requirements of the ventilator (such as high-frequency oscillation ventilation of neonates).

4. The oxygen concentration control error usually needs to be ≤±3% to avoid fluctuations in gas source pressure (such as a drop in oxygen cylinder pressure) affecting the mixing ratio.

5. Accurately control FiO₂ to prevent long-term high-concentration oxygen (>60%) from causing lung damage.
