Integrated deteriorating maintenance and patient scheduling for single medical device with heuristic algorithm

The entire field of information processing in medicine is today already spread out and branched to such an extent that it is no longer possible to set up a survey on relevant literature as a whole. But even in narrow parts of medical informatics it is hardly possible for the individual scientist to keep up to date with new literature. Strictly defined special bibliographies on certain topics are most helpful.In our days, problems of optimal patient scheduling and exploitation of resources are gaining more and more importance. Scientists are working on the solution of these problems in many places.The bibliography on »Patient Scheduling« presented here contains but a few basic theoretical papers on the problem of waiting queues which are of importance in the area of medical care. Most of the papers cited are concerned with practical approaches to a solution and describe current systems in medicine.In listing the literature, we were assisted by Mrs. Wieland, Mr. Dusberger and Mr. Henn, in data acquisition and computer handling by Mrs. Gieß and Mr. Schlaefer. We wish to thank all those mentioned for their assistance.

Medical Device Regulation

Nicht lieferbare Medizinprodukte sind für Kliniken ein Albtraum – mitunter müssen sogar geplante OPs abgesagt werden. Die Folge: Die mit den Kostenträgern vereinbarten Leistungszahlen sind schwieriger zu erfüllen und es könnte zu schwer kompensierbaren Erlöseinbußen für die Leistungserbringer kommen. Die Medical Device Regulation (MDR) wird die Liefersituation von Medizinprodukten ab 2020 wahrscheinlich noch weiter verschärfen.

Clamping devices with constant force or pressure are desired in medical device, such as hemostatic forceps and the artificial sphincter, to prevent soft tissues from injures due to overloading. It is easily obtained by stretching an SMA wire. However, studies with SMA bending round bar have seldom been reported before. This paper studied constant force characteristic of C-shaped round bar with shape memory alloys. Optimization designs of the components were carried out with computational simulation. Numerical results show that the phenomenon of constant force strongly depends on contour curve shape and geometric dimensions of the C-shaped round bar of SMA component.
