|High Throuput Fluidic PCBs for Medical Devices|
|Keywords: PCB, MEMS, Medical|
|Printed circuit boards (PCBs) perform normally wiring, holding and cooling tasks in electronic systems. But with the request for integration of more and more functionality in the devices the PCBs have to take over more and more tasks in a system and will become a functional device and not only the carrier for electronic devices. One of these functions can be fluidics. The usage of PCBs for micro fluidic devices such as pumps and sensors was already reported. In this talk a new research area of the fluidic PCB group at the University of Rostock is presented: The usage of a fluidic PCB technology for the realization of medical fluidic devices with high throughput. The problems to overcome are the creation of high pressure proof channels with a low flow resistance and of course the biocompatibility. In the talk a medical device developed in such a technology will be described. It is a support device for the minimal invasive surgery which has to regulate the pressure in the pneumoperitonaeum, a so called insufflator. For this device flow rates of up to 45l/min CO2 has to deliver and the channel must withstand a pressure of up to 3.5 Bar. The focus in the talk will be the technological challenge of building pressure proof channels in the PCB. The requirements for the usage in medical devices will be explicitly described and the measurement results will be demonstrated. As a conclusion a comparison to a device build in a conventional technology device is given. The criterias are the functional parameters and the production and maintainance costs.|
