The importance of  Bubble Detector:

The most commonly asked question is What is a  sensor? The major use is to detect air bubbles in almost all liquids and tubing materials for medical devices, such as dialysis machines, blood transfusion lines, and other medical devices. And drug supply lines. These detectors play an essential role in the equipment and are necessary to provide a constant flow and avoid air embolism problems. When there is an air detector detecting the air bubble, then we need to remove the air bubbles during the blood transfusion and dialysis process. 

What is An Air Embolism?

Air embolism can occur when gas bubbles enter a vein or artery. This gas bubble prevents blood from flowing through it. An air bubble detector is essential if we are detecting the Therefore, it can be life-threatening, if not done properly. The consequences of air embolism are often unknown and may be overlooked in daily medical practice. For this reason, detector sensors are essential and can prevent life-threatening conditions such as strokes and heart attacks.

Several methods can be used to identify air bubbles in liquids: the photoelectric and ultrasonic methods. If we detect the air bubbles just in time we can avoid major diseases like heart attack and uneven strokes.

Bubble photoelectric sensor:

Photoelectric capacitive air bubble detectors (also known as optical) support the non-invasive detection of liquids and air pockets in the ductwork. Permanent openings are available for most standard pipe sizes. This allows the tube to be well-positioned between the detector sensor’s optical components. When the beam in the sensor is blocked by bubbles or liquid inside the box and reaches a certain threshold—the sensor output changes. However, optical sensors have some drawbacks. First of all, they need to be calibrated only for each liquid used. Some beverages increase the signal strength compared to air. At the same time, other drinks decrease the signal. Air bubble detector you plan to use the sensor with multiple fluids, this might not be an option. Other reasons for concern are:

  • ambient light variation
  • sensor deterioration
  • Contamination in front of the sensor
  • system power change
  • temperature change

All of these factors combined to create an air bubble tube detector that may require constant calibration.

Ultrasonic Bubble Sensor:

The transducer generates an ultrasonic wave on one side inside the ultrasonic detector. It transmits it through the tube to the opposite transducer, which uniformly detects the intensity of the signal. The air bubble detector transmission of ultrasonic waves differs between air bubbles and liquids. Only when there is liquid in the tube does it emit ultrasonic waves. Ultrasonic waves are reflected due to air bubbles. From now on, the received signal will become weaker. Here’s how to use an ultrasonic detector to identify air bubbles inside a pipe. The ultrasonic bubble air detector sensor is non-invasive. And when factory calibrated, No further field calibration is required. The Ultrasonic waves are used to detect the air bubbles in the pipe and avoid any undesired conditions. The bubble detector sensor makes it easy to calibrate the blood transfusion and dialysis of the patients.
