The Role of the Flow Sensor in the Ventilator and the Ventilator LED Lamp Bead

As we all know, since mid -March, the European and American epidemic has intensified. It is common for thousands of people to diagnose thousands of people every day. The United States has often diagnosed more than 10,000 people a day since March 22. In addition to Germany, the mortality rate of Western countries is often very high. Why is this? Because of lack of ventilator. In modern clinical medicine, ventilator function replace the autonomous ventilation function, which is generally used in respiratory failure caused by various reasons, and occupy a very important position in the medical field. What does the flow sensor do in the ventilator? And what kind of LED lamp beads can be used in the ventilator? The function of the flow sensor in the ventilator: the application of the flow sensor in the ventilator has a history of nearly 30 years, and it is generally used in mid -to -high -end ventilator. As an important part of the ventilator air circuit system, it is responsible for converting the inhaled and exhaled gas flow into a electrical signal, and given to the signal processing circuit to complete the inhalation and exhalation of the moisture volume, the amount of ventilation, the flow velocity detection and display of the flow velocity, and the display. Depending on the function and design of the ventilator, the detection value of the flow sensor not only provides display, but also plays a decisive role on the control and alarm of the ventilator. Compare the value, control the servo valve between the two to adjust the inhalation and exhale gas flow; the signal generated by the air and oxygen flow sensor installed at the front of the inhalation system can help the microprocessor control the valve to provide the patient's need The oxygen concentration; the detection value of the flow rate and flow also directly affects the switching of the phase of exhalation and inhalation, the alarm of the upper and lower limit of the ventilation volume, the sensitivity of the flow trigger, the real-time waveform of the airflow and the monitoring display of the P-V-ring, etc., the flow of flow, etc. The quality of the sensor directly affects the accuracy and reliability of the ventilator parameters. The ventilator LED patch lamp beads, more two models with 2835 and 3030. Among them, 2835RGB full -color appearance size/package (L/W/h): 3. 5*2. 8*1. 3mm, color/color: RGB, colloid/lens: transparent plane colloid/Water Clear Flat Mold, EIA specification standard Packaging / EIA STD Package, environmentally friendly products, in line with RoHS requirements / Meet Rohs, Green Product.
