Pressure Sensors in Medical Applications

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure Sensors in Medical Applications

According to a recent market report from Mordor Intelligence, a market intelligence and advisory service, the medical sensors market was valued at USD 12.36 billion in 2019 and is expected to reach a value of USD 20.72 billion by 2025, increasing at a compound annual growth rate (CAGR) of 9.07% over the forecast period (2020 – 2025). The report identifies the significant role that pressure sensors play in medical sensor market. Specific pressure sensor applications include:

  • respiratory breathing circuits (nebulizers, spirometers, patient monitoring)
  • flow/pressure control (therapeutic hospital beds)
  • gas collection (hospital gas supply, oxygen concentrators)
  • sampling/gas flow (blood analysis, gas chromatography, analytical instrument sampling systems)

A specific example of a home health system is continuous positive airway pressure (CPAP) respiratory therapy equipment that can use high sensitivity and accurate pressure sensors.

Also, to avoid poor inhaler techniques that prevent patients from receiving their full therapeutic benefits when using inhalers, some medical equipment manufacturers use pressure sensors in inhalers so individuals can receive proper asthma treatment.

All Sensors offers different types of pressure sensors for many medical applications.

Pressure and Air Sampling

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure and Air Sampling

If water damage has occurred inside your home, especially to the drywall, a remediation company will probably suggest sampling the air to determine if hazardous mold has developed. The process can be rather straightforward and simply consists of pumping a specific volume of air near the area of concern into a container for laboratory analysis. For lower cost, the volumetric sample is obtained by timing a specific airflow for a fixed amount of time. Then the sample can be submitted to an offsite lab.

Air Sampling Equipment

In addition to mold spores, air sampling also can be performed for pollen, insect parts, skin cell fragments, fibers such as asbestos, fiberglass, cellulose, clothing fibers) and organic particulates including ceramic, fly ash, copy toner and more.

In a work or potentially hazardous environment, verifying compliance to regulations on a periodic or even continuous basis can dictate much more accurate and precise readings. In digitally controlled pumps, a built-in airflow indicator can allow adjustment of the airflow from a few (5) to several 1000 (typically 4000 to 5000)ml/min.

SKC's Pocket Pump

SKC’s Pocket Pump displays airflow and pressure and has both constant flow and constant pressure modes. In this case, the pressure is 28.94 inches of mercury (inHg).

For air sampling equipment, All Sensors TLAX Series 4 to 20 mA Output Transmitter can provide the necessary accuracy as well as improved overall long term stability. The sensors have operating pressure ranges of 0.5 to 30 inH2O differential and gauge and 1 to 150 PSI differential and gauge.
