Participation and contribution of pressure sensors in the medical field

baijiahao | 18/03/2021

The pressure sensor is an important component of the ventilator, which can provide necessary help for patients who are fighting against COVID-19.

For more than ten years, All Sensors has continuously provided key components--pressure sensors to the world's leading manufacturers of ventilators and respirators, and its superior product performance has been used by users and leaders in critical care products from all walks of life. They applauded and affirmed, and made quick responses and contributions in the fight against COVID-19.

Amphenol All Sensors Corporation is an industry leader in the design and manufacture of ultra-low pressure sensors. Its products are known for their high accuracy and repeatability, and are especially suitable for low and ultra-low pressure applications in flow measurement and control. Ideal markets for its products include medical, military, industrial, and HVAC. Common applications include ventilators, spirometers, blood pressure monitoring, building monitoring systems, industrial automation, air velocity, and leak detection. The pressure range is as low as 0.25inH2O, as high as 150psi, that is, 62.5pa~1Mpa, and provides a variety of custom port configurations and a variety of excitation voltage options.

In medical ventilators and portable ventilators

The mixture of air and oxygen is delivered to the lungs of the patient through the trachea through a tube placed in the nose and mouth of the patient, so as to deliver air to the patient with respiratory insufficiency in time to properly expand the lungs, thereby maintaining a relatively stable breathing cycle. In this process, the pressure sensor acts as an important helper, providing accurate data for the key parts, so as to ensure the appropriateness and reliability of the air supply. At present, All Sensors pressure sensors are mainly used in hospitals and infant ventilators and portable ventilators. In ventilator applications, pressure sensors monitor relatively low pressures (usually 10 cm H2O). Amphenol All Sensors provides pressure sensors that are critical to the manufacture of medical devices, including but not limited to ventilators.

Oxygen concentrator and O2 therapy

Usually, conditions like asthma, chronic bronchitis, anemia, pulmonary edema and congestive heart failure require oxygen concentrators to provide oxygen therapy for patients, also commonly known as O2 therapy. Oxygen therapy is a medical treatment method that provides a higher level of oxygen concentration to important tissues and organs in the body through an oxygen concentrator. Therefore, oxygen-containing air with a higher concentration of oxygen than the natural oxygen concentration in the outside air is required to deliver to the patient. During this transportation process, the low differential pressure measurement value of the oxygen flow is usually only a few kPA, and the high-precision characteristics of All sensors can provide strong data support for this series of products.

Pressure sensors are used in various medical equipment to provide necessary help for doctors in diagnosis or surgery. Whether it is invasive or non-invasive, blood pressure inside and outside the body can be obtained directly or indirectly through a pressure sensor. Such as the measurement and diagnosis of human blood pressure by measuring the systolic and diastolic blood pressure between heartbeats, the measurement of gastrointestinal pressure during abdominal surgery, the measurement of intraocular pressure during the treatment of glaucoma, the measurement of vital capacity by measuring respiratory flow, and so on.

Pressure sensors can not only be used in the medical industry, but also have more applications in industrial or consumer electronics, such as building monitoring systems, industrial automation, air speed, and leak detection.
