People love to play with bubbles, especially in bathtubs and plastic fills, but bubbles can become a threat in many instances & applications. For example, they can cause severe quality failures in semiconductor process equipment and 3D printing infusion. They can also be life-threatening in medical circumstances that require infusion pumps, blood flow monitoring, and hemodialysis. Thankfully, special sensors, also called bubble sensors, can detect bubbles using ultrasonic energy.
What Are Bubble Sensors?
Bubble sensors are devices used to detect bubbles in almost all tubing and fluid material used in medical devices. They detect bubbles in infusion lines, transfusion lines, and dialysis machines effectively. These air bubble detectors help prevent air embolism problems and maintain a steady flow.
What Is Air Embolism?
Air embolism occurs when a gas bubble enters the artery or vein. When this happens, gas bubbles restrict the movement of blood. It can cause a stroke, heart attacks, and several other health issues. Although the effect of air embolism is not discussed as much as it should, it is life-threatening.
Based on this, ultrasonic bubble detectors have become pretty helpful in the medical sector. They are used to prevent potentially fatal health issues like heart attacks and stroke. In medicine, bubble sensors are used primarily during blood transfusion, hemodialysis, and other operations that require the flow of liquid.
Types Of Bubble Sensors
There are two main types of bubble detector sensors used in the medical sector when treating patients. These sensors are photoelectric bubble sensors and ultrasonic bubble sensors. Although both sensors perform the same function, they are sometimes used for different operations.
Photoelectric Bubble Sensors
Photoelectric bubble sensors or optical bubble sensors are used for the non-invasive detection of air pockets and fluids in the tube. They can be effective for bubble detection for several types of liquids. However, there are known disadvantages in using optical technology such as susceptibility to environmental effects such as light and dust that interfere with long term sensor accuracy & reliability.
Ultrasonic Bubble Sensors
The ultrasonic bubble detector is a much better technology for detecting bubbles. It uses ultrasonic waves for bubble detection; however, the transmission of the ultrasonic waves differs between liquids and bubbles. Ultrasonic waves won’t be transmitted unless there is liquid in the tube. Ultrasonic bubble detectors are entirely non-invasive but have a significant advantage over photoelectric sensors. Unlike the photoelectric sensors, they don’t need further calibration during usage in the field and are not typically affected by most environmental conditions.
