This paper presents the construction of a new medical application system (MAS), unifying blood collecting, sample preparation and analytics in one device. Additionally, the implemented analytical device should be a commercially available lateral flow assay (LFA). Therefore, a universal case has to be designed. A needle system should extract the blood from the patient, while capillary forces transfer the sample through internal feeding into a reservoir. Afterwards, a buffer flushes the reservoir and carries the analyte through the migration distance to the test row. The developed setup utilizes microfluidic mixing structures as for further sample preparation. Thereby, the risk of contamination for the patient and medical personnel could be significantly reduced. Consequently, trained medical personal should not be necessary to operate this setup and increase the overall filed of application. This is especially fundamental when considering an application in case of epidemic events whereas a reliable medical treatment is often not reliable.
