1. System Design & Operation
The JINLING 820 Anesthesia Machine operates as a pneumatically driven and electronically controlled system, supporting closed, semi-closed, and semi-open breathing circuits. Housed in a durable, non-hazardous ABS and metal frame, the machine is both environmentally friendly and robust. It features an automated startup self-check and sensor self-calibration to ensure consistent, fault-free performance from the moment it is powered on.
2. Display & Interface
Equipped with a clear 5.7-inch TFT display, this Anesthesia Machine provides real-time visualization of Pressure-Time and Frequency-Time waveforms, which can be toggled instantly with a single button press. The intuitive interface allows anesthesiologists to monitor ventilation parameters efficiently, enhancing situational awareness and procedural accuracy.
3. Ventilation Modes & Performance
The JINLING 820 Anesthesia Machine supports a range of ventilation modes to accommodate diverse clinical needs:
-
IPPV (VCV)
-
SIPPV (VCV)
-
IMV
-
SIMV
-
MANUAL
Key ventilation parameters include:
-
Tidal Volume: 0–1500 mL
-
Respiratory Frequency: 0–100 bpm
-
SIMV Frequency: 1–20 bpm
-
I:E Ratio: 8:1 to 1:10
-
PEEP Range: 0–2.0 kPa
-
Inspiratory Pressure Trigger: –1.0 to +2.0 kPa
-
Inspiratory Plateau: 0–1 second
-
SIGH Function: One deep breath per 70–120 controlled respirations
4. Gas Delivery & Safety Features
A high-precision four-tube flowmeter ensures accurate delivery of O₂ and N₂O, with flow ranges of 0.1–10 L/min for each gas. 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 and responsive gas delivery.
5. Vaporizer System
The Anesthesia Machine is equipped with a single R-A1 type vaporizer slot, compatible with Enflurane, Isoflurane, and Sevoflurane (Halothane optional). The vaporizer features self-compensating functionality for flow, temperature, and pressure, ensuring consistent anesthetic agent delivery.
6. Safety Alarms & Backup Systems
Patient safety is reinforced through comprehensive audible and visual alarms for:
-
Tidal volume
-
Airway pressure
-
Asphyxia
-
Power failure
-
Oxygen failure
An alarm query function allows quick review of alerts. In case of AC power failure, the Anesthesia Machine automatically switches to backup power mode, ensuring continuous operation without interruption.
7. 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 also 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 replacement.
8. Optional Features
The JINLING 820 Anesthesia Machine can be enhanced with an optional multi-parameter patient monitor, enabling it to function as a comprehensive anesthesia workstation tailored to specific clinical needs.
