Specifications
- The instrument is based on the standards ISO 9360-1, ISO23328-1;
- The instrument is mainly used to test the water loss of heat and moisture exchangers (HME) used in anesthesia and respiratory systems to humidify human respiratory gases.
- Working principle: A sinusoidal gas generator is used to simulate human breathing. The test system is calibrated using a standard HME, and the tidal volume is adjusted. The weight change of the simulated respiratory system and HME is recorded by weighing, and the water mass loss of the HME during breathing is calculated to determine the performance of the HME.
- The tester consists of a sine wave generator, a test host, a moisture generator, a simulated lung, a constant temperature water bath, an insulation box, a gas constant temperature control device, a gas storage container, a gas delivery system, an automatic separation weighing system, a calibration HME and auxiliary test accessories.
- Automatic weighing, using a precision electronic scale with a measuring range of 0-15 kg and an accuracy of ±0.1g. Automatic lifting and lowering of the electronic scale, automatic separation of the test system, automatic recording of system mass changes, and automatic calculation of HME moisture loss.
- Sine wave gas generator, used to generate sine wave gas that simulates human breathing, with adjustable breathing rate from 0 to 30 times/min;
- Automatic adjustment of tidal volume, the system defaults to four levels: 250mL, 500mL, 750mL, and 1000mL.
- A constant temperature water bath ensures that the gases entering the HME from the simulated lung are fully humidified and kept at a constant temperature of 37°C. The constant temperature water bath automatically controls the temperature to a constant of 37°C with a control accuracy of 0.1°C.
- The insulation box is filled with foamed polypropylene material to isolate the internal temperature of the test system from the external environment. A constant temperature control device is used to control the air temperature inside the insulation box at 37°C with a control accuracy of ±0.5°C.
- Gas flow measurement uses a precision electronic flow meter with a response time of 10ms, a maximum resolution of 0.001SLPM, an output fluctuation of ±0.12%/℃, a flow pressure upper limit of 600Pa, and a flow upper limit of 50SLPM;
- Test time can be set to any value between 0-9999H9999 min;
- Calibration HME: The housing contains 81 polyvinyl chloride (PVC) pipes arranged in a 9×9 pattern. Each pipe has an inner diameter of 2mm, an outer diameter of 4mm, and a length of 50mm. It has 22 outer cones, 15 outer cones, and 15 inner cones;
- Simulated lung volume: 2L;
- Display: The system main interface displays real-time data such as running time, water temperature, air temperature, number of breaths, weight, tidal volume, respiratory rate, flow rate, etc.
- Touch screen control, use the touch screen to input parameters and operate the instrument;
- It can run continuously for 4800 hours; power supply: AC220, power 500W;
- Weight: The main unit weighs less than 15 kg.
