Product Description:
YJJ 8412935 ±0-18 L/s (±1080 L/min) Adult Bidirectional Flow Sensor (Thermal Wire Type)
Features:
I. Core Parameters
Measurement Principle: Constant temperature hot wire wind speed type, measuring inhalation and exhalation flow in both directions simultaneously. Built-in Infinity ID intelligent chip, the anesthesia machine automatically identifies and calibrates.
Range: ±0 to 18 L/s (±1080 L/min), suitable for adults and older children.
Accuracy: Full range error ≤ ±2% FS, volume measurement error < 3%, resolution 5 mL/s. Shanxi Public Resources Trading Platform
Airway Parameters: Dead space ≈ 7 mL, air flow resistance < 0.04 kPa/(L/s), low resistance does not increase the patient's respiratory load.
Working Temperature: Environmental 10℃ to 45℃; can be sterilized with ethylene oxide / low-temperature and reused.
Interface Specifications: Respiratory end ISO 15mm standard cone, electrical 2-pin gold-plated contacts; built-in bypass CO₂ sampling hole, compatible with 8290286 sampling tube.
Material: Medical PSU polysulfone heat-resistant transparent shell.
Compatible Models: Fabius 2000/Plus/GS/Tiro/Primus full series operating room anesthesia workstation.
II. Product Usage
1. Closed-loop control of anesthesia machine ventilation (core)
Installed on the exhalation branch, real-time collection of instantaneous flow signals of inhalation and exhalation, feedback to the host servo valve, automatically adjust the air supply volume of the air box, precisely control tidal volume, minute ventilation volume, inspiration-to-expiration ratio I:E, ensuring precise output of mechanical ventilation during the operation.
2. Real-time monitoring of ventilation parameters
Host conversion display: tidal volume VT, minute ventilation volume MV, inspiration peak flow rate, exhalation flow rate waveform, flow rate - volume loop, anesthesiaist adjusts anesthesia and ventilation based on the data.
3. Equipment safety alarm
Leakage in the circuit, dislodgement of endotracheal tube, airway spasm, disconnection of breathing circuit, abnormal ventilation, triggering anesthesia machine high and low flow, low ventilation alarms when flow suddenly changes.
4. CO₂ monitoring kit
Sensor reserved sampling hole, plug in 8290286 CO₂ sampling flexible tube, extract patient's exhaled gas, supply host infrared module to detect EtCO₂ end-tidal carbon dioxide concentration.
III. Model Distinction of the Same Type
8412034: Old model pressure difference type, 8412935 as upgraded replacement model
8410179: Special for newborns (small range ±0.8 L/s)
8403735: Special for Savina ventilator
