M-11 oxygen sensor for Stephan Ventilator new original medical equipment accessories

M-11 oxygen sensor for Stephan Ventilator new original 

► Brief Description

The M-11 oxygen sensor is a new original for the Stephan Ventilator. This sensor has a signal output range of 0.8-12.5mV, a resolution of up to 0.1%, an oxygen concentration measurement range of 0-100%, a service life of up to 4 years, a response time as low as 5 seconds, and a loading resistance greater than 1MΩ. The M-11 oxygen sensor plays a crucial role in ventilators. It is primarily used to measure the oxygen concentration of the mixed gas, unrelated to oxygen concentration control, but as a terminal monitoring method, it can promptly detect whether the oxygen concentration is accurate. When the sensor output voltage exceeds the normal range or the measured value deviates significantly from the set value, the ventilator will issue an alarm.It is compatible with F120, Alia, Stephanie ventilators, CPAP type A/B/C, and the entire Stephan anesthesia machine series.

►Replacement Procedure

1. Locating and Removing

The oxygen cell (sensor) is typically located between the patient's inspiratory end and the air-oxygen mixer.

The sensor connects to the ventilator's circuitry via a physical interface.

Once the sensor is located, carefully disconnect its electrical connection, then remove the old sensor from its slot or airway.

2. Installing the New Sensor

Verification and Cleaning: Remove the new M-11 sensor and confirm the model is correct. Check for any external damage and ensure the interface is compatible.

Installing the Sensor: Insert the new sensor into the slot in the correct orientation. You may need to press it in firmly to ensure a seal at the airway interface.

Connecting the Cable: Securely insert the sensor's connector into the corresponding port on the ventilator.

3. Power-On Test

After installation, connect the ventilator to power and air supply and turn it on.

4. Calibration

Enter Calibration Mode: In the ventilator's main menu or settings menu, locate "FiO2 Calibration" or a similar option.

Introduce calibration gas: As prompted on the screen, the ventilator may automatically introduce a gas of known oxygen concentration into the sensor via a solenoid valve.

Wait for calibration to complete: During the calibration process, the ventilator screen may display "CAL". Please wait patiently until the calibration procedure is completed automatically. Once complete, the device will automatically switch back to normal measurement mode.

►Warning:

It is important to note that the actual service life of the M-11 oxygen sensor is affected by the operating environment: use in high oxygen concentration or high temperature environments will shorten its lifespan. Therefore, regular inspection and timely replacement of the oxygen sensor are necessary measures to ensure the normal operation of the ventilator. Especially when abnormalities are detected in the inhaled oxygen concentration monitoring, the oxygen battery should be considered as potentially failing or nearing the end of its lifespan.

►FAQ:

Q1: How often should I replace the M-11 oxygen sensor?
A1: Typically every 2-4 years, but high oxygen concentrations or temperatures may shorten its lifespan.

Q2: Is this an original or compatible sensor?
A2: This is a brand new original M-11 sensor manufactured for Stephan ventilators.

Q3:What is the product warranty period?
A3: All products have a 90-day warranty, we can replace or refund you within the warranty period.
