Used for inhalation anesthesia, breathing control or assistant breathing, monitoring and displaying the ventilation parameters of the patient.
The CWM-302 system provides continuous gas flow inhalation anesthesia; suitable for closed, semi-closed, and semi-open inhalation anesthesia.
Mechanical ventilation for recovered patients during or after operations.
Suitable for adult or child patients (≥5kg).
Note: There is no absolute contraindication for the anesthesia system, but operators must follow medicine instructions. Caution should be taken for heart, liver, and kidney disease patients.
Main Structure & Working Principles
Anesthesia Ventilator & Respiration Monitor
4-Tube Rotor Flow Meter (O2, N2O)
Vaporizer (Enflurane, Isoflurane, Sevoflurane)
CO2 Absorber System (2000mL capacity)
O2 Faulty Alarm and Protection Device
Key Components:
1. Flow Meter: Equipped with O2/N2O proportion control to ensure O2 concentration ≥25%. If O2 is closed, N2O shuts off automatically. 2. Vaporizer: Features temperature, flow, and pressure compensation with mutual locking devices. 3. APL Valve: Adjusts pressure limit during manual ventilation (Range: 0.04kPa to 7.0kPa). 4. O2 Flush: Provides high-flow oxygen (25-75L/min) directly to the circuit.
Frequently Asked Questions
What is the intended patient range for the CWM-302?
The system is designed for both adult and pediatric patients with a body weight of 5kg or more.
What ventilation modes are available?
It supports multiple modes including VCV, A/C, SIMV-V, AIMV-P, PCV, PSV, Manual, and Stand-by.
How does the hypoxic guard system work?
It includes an N2O cut-off valve and a proportion control device that ensures oxygen concentration remains above 25% at all times.
What happens if the oxygen pressure drops?
The system triggers an audible alarm when O2 pressure is lower than 0.2 MPa and simultaneously cuts off the N2O supply for patient safety.
Does the system include a backup power source?
Yes, the integrated battery provides at least 180 minutes of operation in case of an AC power failure.
What is the capacity of the CO2 absorber?
The CO2 absorber has a large capacity of approximately 2000mL, which helps in efficient gas circulation and CO2 removal.
