Ways To Analyze Blood Effectively During Hemodialysis Treatment

Blood loss and leakage are a few complications that could occur during hemodialysis. If this happens, it can be life-threatening for the patient. Unfortunately, managing such a situation is usually difficult for the doctors and other medical staff. Therefore, analyzing blood effectively during hemodialysis and avoiding blood leakage is essential. Blood leak detectors are an effective method of analyzing blood and preventing blood leakage during hemodialysis. In fact, these devices are implemented in dialysis machines for monitoring the transmission of liquids during hemodialysis. This monitors the dialysate for the smallest trace of blood, ensuring patient safety.

Features Of A Blood Leak Detector

Non-invasive blood leak detectors have optical sensors that can detect the smallest traces of blood present in clear fluids in flexible and transparent tubing. This device reliably detects as little as 0.35 ml/min of blood during dialysis at a hematocrit level of 32% and flow rate of 800 ml/min. This ensures that the medical staff gets even more precise measurements. Additionally, blood leak detectors can help to evaluate the plausibility of the measurement data, ensuring maximum patient safety. Some mini blood component sensors allow patients to carry out their treatment independently, without on-site medical staff.

How Does A Blood Leaks Detector Work?

During hemodialysis, the patient’s blood is passed through a filter known as a dialyzer. Once the blood is passed through the device, it pumps the blood and removes fluids and unwanted materials. After cleaning the blood, it brings it back to the body. The process of cleaning the blood helps to remove waste materials like salt and water from the blood. Blood component detectors are used to identify unwanted leaks in the dialyzer’s blood compartment. Typically, hemodialysis machines have a blood leak alarm. This triggers when blood is detected in any clear fluid. It would trigger even at the smallest amount of blood. Cleaning and filtering blood during hemodialysis is very important. This is because if blood should enter the dialysate membrane, there could be complications. For instance, blood leaks can cause hypotension, loss of consciousness, and cardiac arrest. Thanks to non-invasive blood detectors, these complications can be prevented. The optical sensor in a leak detector can detect red blood cells using a light source. Once it reaches a threshold, an alarm is triggered. Do you need a multipurpose blood leak detector? Are you looking for a reliable manufacturer or supplier of non-invasive fluid detection devices?

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.

Introtek’s Mini Blood Leak Detector

Technology is taking over all aspects of our lives. But most importantly, it has become a vital tool in the medical sector, improving healthcare and saving lives around the world. Technologies like Introtek’s mini blood leak detector are some of the most important advancements in medical technology today.

Introtek Blood Leak Detectors are utilized to detect the smallest amount of blood in dialysates with in clear tubing during dialysis. To ensure patient safety during this process, blood circulation is continuously monitored throughout with special attention focused on the dialysate discharge tube for detection of possible blood leaking through a membrane. Field-programmable blood level thresholds can be easily and reliably set in the BC1 to detect even small trace amounts of blood.
