The design of all types of respiratory equipment faces a common major challenge, namely the use of air pumps from different manufacturers. This means that for each piece of equipment at the same output setting, the actual output will be biased, requiring a flexible sensor function. In addition, the design will be different from each other, and the size and length of the airflow passage will be different, which will affect the packaging requirements and the way of inducing air flow. 
The anesthetic apparatus is used to administer an anesthetic to the patient, so that the patient does not feel the medical clinical operation discomfort after the medicine takes effect, and the pain is reduced or eliminated. Gas mass flow sensors used in anesthesia equipment must accurately measure the flow of air, oxygen, and nitrous oxide to ensure correct air supply. The ventilator can send air and oxygen mixture into and out of the patient's lungs to help them breathe. Therefore, the gas mass flow sensor used in the ventilator not only needs to be able to accurately measure the air and oxygen gas flow, but also can be easily calibrated by the operator, so as to ensure the correct oxygen supply, and can provide accurate flow rate conditions. Make adjustments or calibrations.
Because of the emergence of gas mass flow sensors with a wide range of measurements, designers can choose to optimize components for overall performance. By building blocks, we can fine-tune the calibration with the software, so designers can modify the airflow measurement range for specific designs. This is very important because respiratory devices such as ventilators often use multiple gas mass flow sensors to provide specific airflow ranges and sensitivities for different functional requirements.
The use of circuit board mounted and stainless steel dielectric pressure sensors in anesthesia equipment also allows flexible measurement of air and oxygen pressures. These sensors need to provide accurate and stable operating performance in long-term practical use, so they must have stable readings and small errors in use requirements. The ventilator also has multiple low-pressure circuit board mounted pressure sensors that measure the air and oxygen pressures inhaled and exhaled by the patient to ensure that the pressure does not exceed the set point. These sensors must have high stability and accuracy to ensure repeatable and reliable measurement results for each measurement, helping to improve patient safety.
Board mounted pressure sensors not only provide a wide range of package types, mounting methods, power supply and signal output options, but also have customized calibration functions. These options and features can be cross-platform, greatly simplifying the manufacturing process and supply chain.
Another important issue that needs to be considered in the process of sensor platformization is that product design meets the global market. The design of respiratory equipment will vary significantly from country to country, meaning that different parts of the world will have different packaging requirements. Sensors should provide integrated piping designs that are often used in developed areas, as well as traditional designs that integrate a large number of piping connections that are commonly used in underdeveloped countries and regions.
Platformized Sensors Help Ventilator and Anesthesia Developers
By using modular gas mass flow sensors and pressure sensors, anesthesia equipment and ventilator manufacturers can simplify manufacturing, maintenance, and product use training. Building a platform approach for sensing devices has created thousands of options that not only quickly meet the needs of various package types, product form factors and sizes, but also enable designers to use the same sensor design ideas across the entire product line. For example, the same sensor can be used to design newborn and adult ventilators. The only difference between them is calibration. Honeywell TruStability HSC/SSC–26PC liquid media compatible sensors allow customers to use one port of the sensor to contact a non-aggressive liquid medium such as condensation or deionized water, eliminating the need to protect the sensor from such media. The extra cost.
