How to choose the suitable Pulmonary Function Testing device Ultrasonic type is the best choice. In recent years, with the rapid development of modern electronic technology and bioengineering, Pulmonary Function Testing devices are updating continually, and they are more sophisticated and perfected gradually. Traditionally water seal Pulmonary Function Testing device, wedge Pulmonary Function Testing device,� dry rolling-seal Pulmonary Function Testing device are phrased out of market because they could not connect with electronic computers. After 2000, ultrasonic Pulmonary Function Testing devices have been used internationally to replace traditional differential pressure Pulmonary Function Testing device, turbine Pulmonary Function Testing device and thermal Pulmonary Function Testing device. 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 Pulmonary Function Testing device 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 Pulmonary Function Testing device.

Ultrasonic cavitation generates high shear forces that break particle agglomerates into single dispersed particles. Ultrasonic Emulsifying: Emulsions are dispersions of two or more immiscible liquids. Highly intensive ultrasound supplies the power needed to disperse a liquid phase (dispersed phase) in small droplets in a second phase (continuous phase). In the dispersing zone, imploding cavitation bubbles cause intensive shock waves in the surrounding liquid and result in the formation of liquid jets of high liquid velocity. At appropriate energy density levels, ultrasound can well achieve a mean droplet sizes below 1 micron (micro-emulsion). A wide range of intermediate and consumer products, such as cosmetics and skin lotions, pharmaceutical ointments, varnishes, paints and lubricants and fuels are based wholly or in part of emulsions. Ultrasonic Cell Disintegration This effect can be used for fermentation, digestion and other conversion processes of organic matter. After milling and grinding, ultrasonication makes more of the intra-cellular material e.g. starch as well as the cell wall debris available to the enzymes that convert starch into sugars. It does also increase the surface area exposed to the enzymes during liquefaction or saccharification. This does typically increase the speed and yield of yeast fermentation and other conversion processes, e.g. to boost the ethanol production from biomass.ultrasonic treatment can disintegrate fibrous, cellulosic material into fine particles and break the walls of the cell structure. This releases more of the intra-cellular material, such as starch or sugar into the liquid. In addition to that the cell wall material is being broken into small debris. Ultrasonic Cell Extraction The extraction of enzymes and proteins stored in cells and subcellular particles is an effective application of high-intensity ultrasound, as the extraction of organic compounds contained within the body of plants and seeds by a solvent can be significantly improved. Ultrasound has a potential benefit in the extraction and isolation of novel potentially bioactive components, e.g. from non-utilized by-product streams formed in current processes.
