Ultrasound in Medical Technology (Bubble Counter and THED)

Bubble Counter for Microbubble Detection and Bubble Size Measurement

Ultrasound in Medicine - Bubble Counter

For the application of extracorporal circulation (ECC) during heart surgical interventions the detection and avoiding of microbubbles and micros embolisms become more and more important. In this range we would like to introduce our Bubble Counter products in the field of Medical Technology. Beside the application in medical field it is also possible to use them for measurements or controlling in industrial or technical processes.

Areas of Application of the Bubble Counter

  • Microbubble detection in flowing liquids
  • Bubble size measurement in the area 10-2000 µm (BCC300) or 5-500 µm (BC100)
  • acoustic representation of the number and size of the bubbles
  • Particle detection
  • Air management heart-lung-machine

Why is gas embolism management of great importance for the patient?

The use of extracorporeal circulation in surgical interventions on the heart is often associated with a considerable neurophysiological risk [Roach G.W. et.al.; N. Engl. J. Med. 1996; 335:1857-63]; [Walzer T. et.al.; J. Neurol. Neurosurg. Psychiatry 1997; 6: 644-48]. Microbubbles play a crucial role in this. It could be shown that transcranially detected microembolisms in the central cerebral artery are closely related to the concentration of microbubbles in the extracorporeal circulation and that these can be partly responsible for postoperative neurophysiological deficits. [Borger M.A. et.al.; J. Thorac. Cardiovasc. Surg. 2001; 4: 743-49].
Precise monitoring of the formation and spread of microbubbles in the extracorporeal circulation is therefore essential in order to avoid their occurrence in the patient and to reduce the patient risk.

Uninterrupted monitoring

The continuous advance in perfusion technology, especially bypass systems miniaturization, is very demanding for safety functions. Our BubbleCounter can help to meet these demands. Next to the detection of size and volume of the micro bubbles the BubbleCounter are able to transform each embolism event into an acoustic signal. This provides an alarm function that clearly reduces the embolism risk by early detection of gas contamination.

Do mini-systems pose a higher embolism risk?

Monitoring of air contamination is indispensable especially upon use of new, minimized systems, because de-airing effect is extremely limited by virtue of lacking reservoir. Use and benefit of new respectively additional components (e.g. venous bubble traps) can be objectively assessed and, thus, may result in cost savings.
