System Overview & Design
The JINLING 850 Standard Model Anesthesia Machine operates as a pneumatically driven and electronically controlled system, supporting closed, semi-closed, and semi-open breathing circuits. It is constructed with a non-hazardous, environmentally friendly ABS and metal frame, combining durability with an elegant design. The machine is equipped with an automated startup self-check and an automatic self-calibrating sensor system to ensure optimal performance from the moment it is powered on.
Advanced Display & User Interface
This Anesthesia Machine features a vibrant 8.4-inch color TFT display capable of showing real-time waveforms including Pressure-Time, Frequency-Time, Pressure-Volume, and Frequency-Volume. The waveforms can be cycled instantly with a single button press, providing anesthesiologists with clear and immediate visual feedback for enhanced monitoring and control.
Comprehensive Ventilation Modes
The Anesthesia Machine supports a variety of ventilation modes to meet diverse clinical needs:
-
IPPV (VCV)
-
SIPPV (VCV)
-
PCV
-
IMV
-
SIMV
-
Manual
Key ventilation parameters include:
-
Tidal Volume: 0–1500 mL
-
Respiration Frequency: 0–100 bpm
-
IMV Frequency: 1–20 bpm
-
I:E Ratio: 8:1 to 1:10
-
Inspiratory Plateau: 0–1 second
-
PEEP Range: 0–2.0 kPa
-
Inspiratory Pressure Trigger: –1.0 to +2.0 kPa
-
SIGH Function: One deep breath per 70–120 controlled respirations
A high-precision five-tube flowmeter ensures accurate delivery of O₂, N₂O, and Air, each adjustable from 0.1 to 10 L/min. The system includes an interlocking oxygen-nitrous oxide supply mechanism that guarantees oxygen concentration never falls below 21%. An electronic pressure differential flow sensor and imported respiratory control valve contribute to stable, reliable, and rapid gas delivery.
Enhanced Vaporizer System
Featuring dual PA-I type vaporizer slots, this Anesthesia Machine offers flexibility in anesthetic agent selection, including Enflurane, Isoflurane, and Sevoflurane (Halothane optional). The vaporizer is equipped with self-compensating functionality for flow, temperature, and pressure, ensuring consistent and accurate agent delivery. An advanced Adjustable Pressure Limiting (APL) valve is included, making the system suitable for both low and ultra-low flow anesthesia techniques.
Integrated Safety & Alarm Systems
Patient safety is reinforced through comprehensive audible and visual alarms for:
-
Tidal volume
-
Airway pressure
-
Oxygen concentration
-
Asphyxia
-
Power failure
-
Oxygen failure
The system also features an alarm query function for quick troubleshooting. In the event of an AC power outage, the Anesthesia Machine automatically switches to backup power mode, ensuring uninterrupted operation.
Circuit & Accessories
The integrated metallic modular respiratory circuit is designed for durability and ease of maintenance, with reliable sealing even under high-temperature disinfection. The machine includes an advanced rotating soda lime (Na-lime) tank made from imported PPSU material, resistant to temperatures up to 134°C, and allows for quick one-handed replacement.
Optional Features
The JINLING 850 Standard Model Anesthesia Machine can be enhanced with an optional patient monitor and EtCO₂ parameter monitoring module (range: 0%–13.2% volume ratio), enabling it to function as a comprehensive anesthesia workstation.
