8410185 Sensors For Respiratory Anesthesia Machines Gas Sensor   

Basic Information:

• Brand: Drager
• Model: 8410185
• Product Type: Sensor for breathing anesthesia machines (specifically may be an oxygen sensor or flow sensor, subject to confirmation based on the equipment model)
• Applicable Equipment: Compatible with Drager series breathing anesthesia machines (such as Fabius, Primus, etc.)
• Origin: Germany (headquarters of Drager, with some components possibly produced in other countries)

Technical Parameters:

• Measurement Range:
  • If it is an oxygen sensor, the measurement range is usually 0%–100% O₂;
  • If it is a flow sensor, the measurement range shall be determined according to the specific model, generally covering the clinically commonly used respiratory flow range (e.g., 0–150L/min).
• Accuracy:
  • The accuracy of the oxygen sensor is usually ≤±2% FS (full scale);
  • The accuracy of the flow sensor is ≤±3% of the reading or ±0.5L/min (taking the larger value).
• Response Time:
  • Oxygen sensor: T90 (reaching 90% response) ≤10 seconds;
  • Flow sensor: response time ≤50ms when the airflow changes.
• Operating Temperature: 5°C–40°C (in line with the environmental requirements of medical equipment)
• Interface Type: Dedicated plug-in interface, compatible with the mainboard or module of Drager equipment
• Power Supply Mode: Internal power supply of the equipment (usually DC 5V or 12V)

Product Features:

• High Accuracy: Adopts electrochemical or thermal measurement principles to ensure stable and reliable data, meeting the high-precision requirements of clinical anesthesia for gas concentration and flow.
• Anti-interference: The sensor design has the ability to resist water vapor and corrosion, reducing errors caused by anesthetic gases, moisture, and other factors in clinical use.
• Easy Maintenance: Supports hot-swap replacement without shutdown calibration, and some models have an automatic calibration function (such as zero and span calibration for oxygen sensors).
• Safety Certification: Complies with medical equipment certification standards such as CE and ISO 13485, and has passed biocompatibility tests to ensure patient safety.

Application Scenarios:

• Breathing Anesthesia Machines: Used for real-time monitoring of parameters such as oxygen concentration and respiratory flow in the inhaled/exhaled gas of patients, providing data support for anesthetic depth control and ventilation management.
• Intensive Care Equipment: Some models can be compatible with intensive care ventilators to assist in monitoring gas parameters during mechanical ventilation.

Installation and Maintenance:

• Installation Method: Directly insert into the sensor slot of the equipment, fix it with a buckle or screw, and use it after completing calibration according to the instructions.
• Replacement Cycle:
  • Oxygen sensor: It is generally recommended to replace it every 1–2 years (affected by usage frequency and environment);
  • Flow sensor: There is no clear replacement cycle. If the measurement deviation exceeds the range or a fault code appears, it needs to be replaced in a timely manner.
• Calibration Requirements: Standard gases (such as 21% O₂, 100% O₂) are required for calibration when installing for the first time or regularly (such as every 6 months).

Precautions:

• No Disassembly: The interior of the sensor is a precision component. Disassembly by non-professionals may cause damage or measurement failure.
• Storage Conditions: Store in a dry environment without corrosive gases, at a temperature of 0°C–30°C and a humidity of ≤80%RH.
• Compatibility: Only applicable to the specified models of Drager equipment. Do not mix it with equipment of other brands.

Packaging and Certifications:

• Packaging: Independent anti-static packaging, including instructions and a calibration certificate.
• Certifications: International medical certifications such as CE, ISO 13485, and FDA (if applicable).
