CG Series Clamp-on Ultrasonic Flow Sensors / Flow Meters for Medical Devices

In the operation of various medical devices, the accurate measurement of medical liquids such as blood or dialysis fluid in the tubing is crucial. Abnormalities in the fluid flow rate could lead to severe consequences.

The CG series ultrasonic flow sensors/flow meters provide medical device manufacturers with a non-invasive flow rate measurement solution for verifying/monitoring the performance of fluid pumps in medical devices.

CG series ultrasonic flow sensor/flow meter is particularly suitable for medical devices with high accuracy flow measurement requirements, such as ECMO, hemodialysis machines, cardiopulmonary bypass machines, surgical perfusion systems, organ transplantation systems, heart-lung machines, blood pumps, etc.

Industry Challenges

Dynamic Flow Conditions

In devices such as artificial heart pump, ECMO and hemodialysis machines, flow rates can fluctuate rapidly and unpredictably due to patient conditions and treatment processes. Accurately monitor the dynamic flow conditions in real time poses a significant challenge.

01
Cleanliness

For medical devices that handle blood, such as hemodialysis machines and ECMO systems, it is essential the flow sensors/ flow meters do not come into direct contact with the blood or dialysis fluid. Non-invasive measurement techniques are designed to prevent contamination while being easy to maintain and inspect.

02
Bubble Detection

Air bubbles in the medical fluid circuit can lead to inaccurate measurements and create potentially dangerous situations for patients. A reliable method to measure liquids while simultaneously identifying and alerting operators to any air bubbles is a considerable challenge.

Application Overview

XY-TEK CG series ultrasonic flow sensors/flow meters can be used in the following medical devices

ECMO
Measurement of blood flow rates and detection of air bubbles in the circuit to ensure patient safety and optimal function.
Hemodialysis Machines (HD)
Continuous monitoring of blood flow to provide real-time feedback on treatment efficacy and to adjust parameters as needed.
Peritoneal Dialysis (PD)
Ongoing monitoring of blood flow to ensure proper dialysis and timely adjustments to the treatment process.
Organ Perfusion Systems
Measurement of both perfusion fluids and blood flow to ensure adequate nutrient and oxygen delivery to organs during transplantation or therapy.
Heart Pumps
Continuous monitoring of liquid flow within heart pump systems to maintain optimal cardiac support and function.
Contrast Media Pumps / Infusion Pump
Accurate measurement of injection doses of contrast agents to enhance imaging clarity and improve diagnostic accuracy.
Cryoablation Devices
Exact heating liquids flow rate measurement to ensure controlled application of thermal energy for effective ablation procedures.

By utilizing CG series non-invasive ultrasonic flow sensors / flow meters, medical devices can achieve high levels of accuracy, reliability, and efficiency in flow measurement processes, ensuring device performance and improve patient treatment experience
