Pressure Sensors for the Medical Industry

Posted by Seta Davidian on Dec 4, 2019 1:05:40 PM

In the medical industry, board level pressure sensors are commonly used in patient monitoring equipment. When used in treatment equipment, such as drug delivery systems or respiratory devices, they can act as monitors that trigger upon reaching a preset threshold and tell the control units to continue, change, or cease treatment.

Servoflo has worked with Fortune 500 major medical equipment manufacturers by providing pressure sensors and other environmental sensors in applications such as:

 
  • Respirators and breath detection equipment
  • O2 concentrators and conservers
  • Deep vein thrombosis treatment
  • Infusion pumps
  • Inflatable mattresses
  • Blood pressure measurement

Pressure Sensors for Respirators and Breath Detection Equipment

Our pressure sensors for respirator and breath detection equipment generally monitor low-pressure conditions. They come in a variety of gauge or differential models, digital or analog outputs, and supply voltages. A good example of a pressure sensor is the AL4 Series.  The AL4 has various pressure ranges as low as 0-1 kPa (0.145 psi) with a digital output. What makes the AL4 special is that it has a high overpressure of 15 psi.

Pressure Sensors and Oxygen Sensors for O2 Concentrators and Conservers

Oxygen concentrators take in air, filter out impurities and other gases, and deliver pure oxygen to patients who require oxygen therapy, such as ones undergoing surgery or treatment for lung disease. Due to their critical function, these machines require highly accurate and consistent pressure sensors that can ensure precise and accurate control over treatment.oxygen-concentrator-header (1)

There are two applications for pressure sensors. The first is breath detection, similar to the respirator application described above. The second is to monitor the pressure in the oxygen line, which typically runs between 30-40 psi.

In this pressure range, there are many choices for sensors. Because there are so many options to choose from, Servoflo can help narrow down the choices for you by helping you choose a sensor based on your exact requirements. This way, you will not pick a sensor that is neither not accurate enough nor too accurate (& higher cost) for your application.

We also offer oxygen sensors that monitor the oxygen percentages delivered to the patient. Check out the product page to more about our selection of pressure sensors and oxygen sensors for O2 concentrators and conservers.

Pressure Sensors for Deep Vein Thrombosis Treatment

Deep vein thrombosis, also referred to as DVT, occurs when a blood clot develops in a vein located deep within the body. Pneumatic compression devices can prevent DVT or facilitate treatment by promoting circulation and lymphatic drainage. Typical pressures run about 5 psi.

Our pressure sensors for deep vein thrombosis treatment equipment feature a variety of specifications, including in regard to outputs, pressure ranges, and accuracy levels, to ensure that individualized DVT treatments occur as expected.

Infusion Pumps

Medical professionals use infusion pumps in hospitals, medical offices, nursing homes, and private residences to deliver vital fluids, such as nutrients, medication, or saline, to a patient’s body. These machines need accurate pressure sensors to maintain a controlled flow. The pressure sensors are used to monitor the pump’s backpressure to ensure that the pump is working correctly.

Inflatable Mattresses

Medical inflatable mattresses have more specialized functions than traditional inflatable mattresses. They enhance circulation to prevent soreness, stress, or decreased blood flow while providing support and comfort. Patients use medical inflatable mattresses during extended periods of bed rest to reduce the risk of skin shearing and pressure sores. Different varieties of these mattresses need pressure sensors, typically 3 psi and below, to prevent air loss or replenish lost air.

Our line of sensors facilitates the maintenance of stable, comfortable pressure levels and monitor the mattress’s fluid conditions to protect the patient. Check out the product page to more about our selection of inflatable mattress pressure sensors.

Blood Pressure Measurement

Blood pressure measurement is one of the main applications of medical pressure sensors. The sensors allow for non-invasive measurement of blood pressure, providing insight into a patient’s condition during routine appointments, extended hospital stays, and medical treatments. The pressure sensors are used in electronic blood pressure equipment (not the traditional mechanical units used in a doctor’s office).

Our pressure sensors come in a variety of power requirement, display, pressure threshold, and size options. We have pressure sensors designed specifically for blood pressure instrumentation. The models include the AP3/AG3NIBP. This is a standard sensor specially calibrated  for +/- 3 mm of mercury. Check out the product page to more about our selection of blood pressure sensors.
