8412001 Flow Sensor Accessories

Basic Information:

• Brand: Drager
• Model: 8412001
• Product Type: Possibly a gas filter, flow sensor, or battery component for anesthesia machines/ventilators (to be confirmed based on the equipment model)
• Applicable Equipment: Compatible with Drager series anesthesia machines (e.g., Fabius, Primus) or ventilators
• Purpose: May be used for gas filtration, flow monitoring, or equipment power supply

Product Features:

• Compatibility: Specifically designed for Drager equipment to avoid malfunctions due to interface mismatches;
• Safety: If it is a filter, it uses a hydrophobic membrane design to prevent liquid from entering the equipment; if it is a sensor, it has an anti-corrosion coating;
• Easy Maintenance: Supports plug-and-play, and some models can be automatically calibrated (e.g., filter replacement prompts, sensor zero-point calibration);
• Certifications: Complies with medical device standards such as CE and ISO 13485, and some models are FDA-certified.

Application Scenarios:

• Anesthesia machine maintenance: Used to replace aging filters or sensors to ensure gas monitoring accuracy;
• Emergency backup: Battery components can maintain equipment operation for a short time during power outages to ensure surgical safety;
• Equipment calibration: New sensors need to be calibrated with standard gases (e.g., 21% O₂) after installation.

Installation and Replacement:

• Installation Method:
  • Filter: Unscrew the equipment filter chamber and directly replace the old filter element;
  • Sensor: Disconnect the power supply, plug in and replace, and complete initialization through the equipment menu;
  • Battery: Disconnect the connection, install according to polarity, and charge for 4 hours when using for the first time.
• Replacement Cycle:
  • Filter: Replace every 6 months or after 500 hours of use;
  • Sensor: It is recommended to replace it every 1–2 years (depending on usage frequency and environment);
  • Battery: Replace when the battery life drops to 80% of the rated value.

Precautions:

1. Do not mix with non-original parts: Non-original accessories may cause equipment malfunctions or measurement deviations;
2. Storage requirements: Filters should be stored in a dry and dust-free environment, and sensors should avoid contact with corrosive gases;
3. Calibration requirements: After replacing the sensor, it must be calibrated with Drager original calibration gases (e.g., O₂, N₂O standard gases);
4. Waste disposal: Medical-grade consumables should be discarded according to the hospital's infectious waste disposal procedures.
