The BMBF joint project "VisIMon", led by the German Research Center for Artificial Intelligence, aims to enable automated monitoring that will contribute to improved patient care while at the same time reducing the workload on staff. "VisIMon" stands for a networked, intelligent and interactive system for the continuous, perioperative monitoring and control of an irrigation device and for the functional monitoring of the lower urinary tract.
Since the end of 2017, an interdisciplinary team of scientists, physicians and industry has been developing a small module worn on the body that monitors the irrigation process with the aid of various sensors and which can ideally be integrated in established care procedures. Innovative data handling approaches make it possible to realize completely new concepts - such as medical devices that automatically exchange data with the hospital's IT network. With more than 200,000 applications per year in Germany, the development is extremely attractive not only from a medical but also from an economic point of view.
The system consists of an adhesive ultrasonic transducer patch, which, together with miniaturized electronics and automated evaluation algorithms, will be used to monitor bladder irrigation and detect possible bleeding. A patented ultrasound patch technology by IBMT was used to develop the highly compact 32-element sensor that can be attached to the skin for continuous postoperative monitoring of the bladder. The newly developed 32-channel electronics, on which the ultrasound data are processed and evaluated, can be controlled via mobile consumer devices (e. g. a tablet). With the selected system concept, a large part of the data processing - such as the reconstruction of the measured signals to cross-sectional images of the bladder - is carried out on the tablet. The concept not only leads to lower costs, but also allows to take profit from the continuously improving performance of new end-user devices. The "VisIMon" software is also designed to forward data from various patient systems together with other parameters to central processing units in order to optimally ensure the continuous monitoring of bladder irrigation, which is indispensable after a surgical procedure, even in a tense staff situation.
