Drager 8417029 Pressure Regulator Spare Part Neonatal Ventilator Oxygen Channel Component

Drager 8417029 Pressure Regulator Spare Part Neonatal Ventilator Oxygen Channel Component

 
 
► Brief Introduction
 

This is a brand new, original replacement part, part number 8417029. It is a pressure regulator valve in the oxygen circuit of a ventilator, responsible for stabilizing the oxygen supply pressure. This pressure regulator valve is different from the 8413666 pressure regulator valve, which is a compressed air channel pressure regulator valve.

The valve housing is marked with a unidirectional airflow direction. Proper installation according to the airflow direction prevents reverse airflow from causing equipment malfunction.

This pressure regulator valve is individually packaged in an anti-static bag to prevent static electricity damage to the internal components during transportation, and also provides dust and moisture protection.

 
 
► Features

1. Stabilizes Oxygen Supply Pressure

Hospital central oxygen supply lines experience pressure fluctuations. This pressure regulating valve stabilizes the fluctuating oxygen intake pressure within the ventilator's required range, ensuring a stable oxygen supply.

2. High-Pressure Buffer Protection

When a momentary pressure peak occurs in the oxygen supply line, the pressure regulating valve buffers and limits the flow, preventing high-pressure oxygen from directly impacting the ventilator's internal precision components, reducing the probability of damage.

3. Stabilizes Oxygen Concentration Output

Once the oxygen supply pressure is consistently stable, the ventilator's air-to-oxygen ratio remains unaffected by pressure fluctuations, maintaining a stable output oxygen concentration and preventing sudden fluctuations in oxygen concentration in newborns.

4. One-Way Flow

Allows only unidirectional oxygen flow; during equipment shutdown, it prevents backflow of mixed gas, avoiding contamination of upstream oxygen supply lines and internal sensing elements.

►FAQ
 

Q1: Models 8417029 and 8413666 look almost identical. Can they be used interchangeably?

A1: Absolutely not interchangeable. 8417029 is used for the oxygen channel, and 8413666 is used for the compressed air channel. Their internal pressure regulating parameters and sealing material standards differ; mixing them will lead to abnormal gas supply pressure and uncontrolled oxygen concentration.

Q2: What debugging work needs to be done after replacing the pressure regulating valve?

A2: Install and power on the machine, run it continuously for 30 minutes, and observe the oxygen supply pressure reading in real time; simultaneously monitor the ventilator's output oxygen concentration. Only when the value is stable and without drift is the replacement considered qualified.

Q3: If the equipment simultaneously alarms for both the oxygen and air supply lines, does this mean both pressure regulating valves are damaged?

A3: Most likely not. First, check the external main gas supply; only consider replacing 8417029 if the oxygen channel alarm continues.
