Mindray Synovent E3 E5 ventilator Oxygen TSI flow sensor 840206 Oxygen flow sensor

Mindray Synovent E3 E5 ventilator Oxygen TSI flow sensor 840206 Oxygen flow sensor

The Mindray TSI 840206 Flow Sensor is a precision-engineered OEM mass flow sensor designed specifically for integration into the Mindray SynoVent E3 and E5 intensive care ventilators. Manufactured by TSI Incorporated, a leading specialist in flow measurement technology since 1958, this variable orifice flow sensor provides high-accuracy bidirectional gas flow measurement essential for precise ventilator control and patient respiratory monitoring. The sensor utilizes advanced thermal mass flow sensing technology with oxygen calibration, delivering consistent measurement accuracy regardless of gas temperature or pressure variations. Engineered for embedded medical device applications, the compact sensor integrates seamlessly with the SynoVent ventilator's electronic control systems, supporting real-time flow signal acquisition for tidal volume calculation, minute ventilation monitoring, and closed-loop ventilation feedback control. The sensor's robust construction and fast response time make it ideal for the demanding environment of intensive care ventilation where reliable, continuous flow measurement is critical for patient safety.

Specification of ventilator parts:

This critical flow measurement component serves as the primary gas flow sensing element in the Mindray SynoVent E3 and E5 ICU ventilators, extensively deployed in intensive care units (ICUs), intermediate care wards, post-operative recovery units, and emergency departments requiring sophisticated mechanical ventilation capabilities. The flow sensor enables accurate measurement of inspiratory and expiratory gas flows essential for calculating tidal volumes, minute ventilation, and respiratory mechanics parameters displayed on the 12.1-inch monitoring screen. Respiratory therapists and critical care physicians rely on this component to obtain precise flow-volume loops, triggering signals for patient-ventilator synchrony assessment, and supporting the advanced ventilation modes including SIMV, CPAP, NIV, DuoLevel, and APRV. The sensor's bidirectional measurement capability enables comprehensive breath-by-breath analysis, supporting lung-protective ventilation strategies with tidal volumes as low as 20 ml for neonatal patients. Its integration with the SynoVent's proximal flow-sensor system ensures minimal dead space and low resistance, providing total precision and control throughout the ventilation period.

Advantage :

Exceptional Response Speed: With a 5-millisecond response time, the TSI 840206 captures rapid flow transients during the respiratory cycle, enabling accurate measurement of transient flow patterns, early detection of patient breathing efforts, and precise triggering for assisted ventilation modes.

Wide Measurement Range: The 0-300 L/min flow range with single-sensor coverage eliminates the need for range switching or multiple sensors, supporting accurate measurement across adult, pediatric, and neonatal patient populations from 20 ml tidal volumes to high-flow ventilation requirements.

Low Pressure Drop Design: The 18 cm H₂O pressure drop at maximum flow minimizes the sensor's impact on breathing circuit dynamics, reducing work of breathing for spontaneously breathing patients and ensuring accurate volume delivery regardless of circuit configuration.

Mass Flow Technology Independence: Unlike volumetric flow sensors, the thermal mass flow measurement provides readings independent of gas temperature and pressure variations, ensuring consistent accuracy throughout environmental changes and across diverse clinical settings.

Integrated Temperature Compensation: Built-in temperature output and automatic compensation circuitry eliminates measurement drift caused by warm exhaled gases or ambient temperature fluctuations, maintaining calibration accuracy throughout extended clinical use without frequent recalibration requirements.

Chemical Resistance: The sensor construction tolerates humidified gases and oxygen therapy environments with moisture, unlike sensors limited to dry gas applications, supporting reliable operation with heated humidifiers commonly used in prolonged mechanical ventilation.
