1. Scope of application: Suitable for patients with difficulty in expelling lung secretions or pulmonary insufficiency caused by mucus obstruction in medical institutions, which can promote airway clearing and expectoration or improve bronchial drainage.
2. Output mode: atomizer + expectoration device, dual-channel output, suitable for adults and children.
3. Atomizer: A pneumatic particle atomizer is used to atomize the liquid into nano-scale molecules for patients to inhale to achieve the effect of auxiliary treatment (the atomizer must be a medical device product with a registration certificate or filing certificate).
4. Human-computer dialogue mode: ≥8-inch head-up color touch screen, screen protection (180-degree peel strength: 240-260gf; temperature resistance: 150-180℃ instantaneous; adhesion: 8-12G).
V. Working mode (with atomization mode and sputum discharge mode):
5.1 Atomization mode:
5.1.1 Maximum atomization volume: ≥0.20mL/min;
5.1.2 Gas flow rate: ≥6L/min;
5.1.3 Residual liquid volume: ≤0.8mL;
5.1.4 Normal working pressure: 75kPa～105kPa.
5.1.5 The aerodynamic characteristics of the atomizer mist particles meet the following requirements:
5.1.5.1 The median particle size of the mist particles is 3.5um, and the error does not exceed 25%;
5.1.5.2 The proportion of atomized particles with a diameter of 1um～10um generated by the atomizer is greater than 80%;
5.1.5.3 The proportion of atomized particles with a diameter of ≤5μm generated by the atomizer is greater than 50%.
5.2 Expectoration mode:
5.2.1 Single-frequency expectoration mode: The pneumatic frequency is adjustable within the range of (5-20) Hz.
5.2.2 Multi-frequency expectoration mode: According to different patient conditions, you can quickly customize ≥6 expectoration mode parameters and save them.
VI. Working time setting: Atomization mode is adjustable from 1-99min, expectoration mode (single frequency/multi-frequency) is adjustable from 1-60min, and the step value is 1min.
VII. Working frequency setting: The frequency can be adjusted in the range of 5Hz-20Hz, and the step value is 2.5Hz (you can press and hold the button to adjust it continuously).
VIII. Working pressure setting: The pressure can be adjusted in the range of 1.5kPa-3.9kPa (you can press and hold the button to adjust it continuously).
IX. Start the one-button emergency stop device, and the pressure of the inflated airbag can drop to below 0.2kPa within 10s to ensure the safety of the patient.
10. Intelligent control of operating intensity. When the set parameters are too high, the system pops up a prompt interface, requiring the operator to reconfirm the set parameters, which complies with the medical device usability engineering.
11. Noise: When the whole machine is working normally, the noise is ≤65dB(A).
12. Real-time monitoring function: Real-time monitoring and display of working frequency and pressure during the operation of the equipment.
13. Memory function: When the equipment is working, the power is abnormally cut off, and the working time, frequency and pressure parameters before the power off are automatically restored after the machine is turned on.
14. The C-type structure design is adopted to ensure that the gas channel is stored stably.
15. It has a folding storage device, and the storage space utilization rate is increased by more than 20%.
16. This series of products has NMPA certification and the software copyright registration certificate of the whole chest oscillation sputum machine.
