How to choose the suitable spirometer？ Ultrasonic type is the best choice.

In recent years, with the rapid development of modern electronic technology and bioengineering, spirometers are updating continually, and they are more sophisticated and perfected gradually. Traditionally water seal spirometer, wedge Spirometer, dry rolling-seal spirometer are phrased out of market because they could not connect with electronic computers.

After 2000, ultrasonic spirometers have been used internationally to replace traditional differential pressure spirometer, turbine spirometer and thermal spirometer. The main reason is that these three principles have some limitations as below:

1. Hygiene problem: it is difficult to clean thoroughly, and there is a very high risk of cross-infection in long-term use;

2. Unable to measure lower flow;

3. Heavy reliance on gas composition and temperature;

4. Calibration and adjustment required

Principles of ultrasonic spirometer

The ultrasonic time difference method uses a pair of ultrasonic transducers to alternately (or simultaneously) transmit and receive ultrasonic waves. By observing the difference in the propagation time between the upstream and the backward flow of the ultrasonic in the medium (gas or liquid), the fluid velocity is measured indirectly, and then calculate the flow data based on fluid velocity.

The flow measurement based on the ultrasonic principle is only influenced by the flow and geometry, and accuracy will not be affected by temperature, gas composition, humidity or pressure. So it is a perfect alternative to differential pressure and turbine principles, and is the best choice for spirometer.

Advantages for ultrasonic spirometer:

1.No drift, no preheating, no calibration, no maintenance (flow measurement only depends on time measurement and sensor geometry, so no calibration)

2.Non-contact flow detection technology, the ultrasound probe does not touch the patient, preventing cross infection

3.High measurement accuracy, especially for very weak airflow

4.Direct flow measurement, wide linear range, no nonlinear distortion

5.There are no obstacles in the middle of the breathing tube, no breathing resistance

6.Not afraid of water vapor, real-time BTPS correction

7.The sensor is not affected by humidity, air pressure and pollution

8.Can obtain gas concentration information at the same time

9.Greatly expanded the scope of application: adults-children-newborns
