Detecting Blood Leakage During Dialysis Therapy

Blood loss and leakage are serious complications that occur during dialysis therapies. These occurrences can be life-threatening for the patient, and difficult for the medical staff and nephrology nurses. This is where a blood leak detector comes in handy. It is used for monitoring the transmission of liquids.

How Does a Haemodialysis Machine Detect Blood Leaks?

Blood leak detectors identify unwanted blood leaks in the filter’s blood compartment. Haemodialysis machines come with a blood leak alarm, which detects even minor amounts of blood in any clear fluid.

During hemodialysis, a patient’s blood passes through the filter, known as a dialyzer. The dialysis machine pumps the blood, removes the fluids and unwanted materials, and brings the blood back to the body. This process filters waste, like water and salt, from the blood.

The cleaning and filtering of blood are important as blood is not supposed to cross the dialysate membrane. If the blood comes in contact with the non-sterile dialysate, it can endanger the patient’s life. Due to dialyzer reuse, it has become common for the membrane to rupture due to bleach and heat disinfection.

According to some clinical findings, blood loss can cause loss of consciousness, hypotension, and cardiac arrest. In case of an insertion of a dialysis catheter, it can further result in chest, neck, or shoulder pain, groin or lower abdominal pain, or hemoptysis.

The optical sensor in a detector uses a light source to detect the red blood cells. Once a threshold reaches, an alarm is triggered. This sensor can then be readjusted using a different wavelength for a different device.

The Benefits of a Non-invasive Blood Detector

According to the American Nephrology Nurses’ Association VND survey reports, almost half of the patients that receive dialysis are concerned about serious blood loss. This is why many non-invasive blood detector systems such as pad, optical, and wetness sensors are designed for use in dialysis therapy. In the same manner, Introtek’s BC1 mini blood component detector comes with cutting-edge sensing capacities to detect fluids within clear tubing. It consists of the following properties:

  • A non-invasive optical technology
  • Low-power consumption
  • Free-entry and compact design
  • Field calibratable
  • Wide-ranging tubing sizes
  • Remote electronics options
  • Integrable electronics

The devices come with high-sensing technology to prevent a false blood leak alarm. False alarms are usually caused by air bubbles in the tube or malfunctions in the detector system due to grease deposits.

The Introtek detector can help with specific medical applications and prevent blood loss and contamination of fluids in hemodialysis. Modifications in the design can also be done if customers require specific solutions. To learn more, visit our website.
