Project Description:
Maquet Getinge is a global player in the development and manufacturing of life-supporting devices, such as the Rotaflow II.
The Rotaflow II system is a reliable and high-performance solution for extracorporeal life support (ECLS). It can be used for both veno-arterial (VA) and veno-venous (VV) ECLS/ECMO applications.
VA-ECMO supports both heart and lung function in cases of cardiac and respiratory failure, while VV-ECMO is used to treat patients with severe lung insufficiency who cannot be supported by conventional ventilation strategies. Both ECMO approaches can aid recovery or serve as a bridge to further treatment.
The Cardiohelp System is a compact heart-lung support system suitable for a wide range of applications in intensive care, emergency medicine, cardiology, and cardiac surgery. Its portability enables rapid deployment for in-hospital or inter-hospital transport of patients requiring respiratory and/or circulatory support.
The HCU 40 hypo-/hyperthermia unit features two independent water circuits.
The first circuit delivers temperature-controlled water to the oxygenator heat exchanger and warming/cooling blankets.
The second circuit supplies the cardioplegia heat exchanger with tempered water.
The water tank for both the patient and cardioplegia circuits is divided into two sections, allowing for rapid temperature adjustments at the outlets.
High-efficiency cooling plates, a powerful compressor, and a fast ice-generation technique provide the HCU 40 with exceptional cooling performance.
The unit is also equipped with generously sized heaters and an intelligent electronic control system for both heating and cooling components.
Project Description
Due to the long-term use of proven components and the current global situation regarding the procurement and availability of electronic, electromagnetic, and electrical components and assemblies, there has been an increasing number of component discontinuations. This poses a significant risk that, in the foreseeable future, devices may no longer be reproduced within the usual lead times.
Additionally, the repair of defective devices in the field is being delayed—or in extreme cases, may no longer be feasible at all. Stockpiling components is only a temporary and often costly method of safeguarding delivery capability.
A far more sustainable approach is Obsolescence Management, a service that seleon GmbH has been offering and implementing for some time. This involves a close examination of components that have already been discontinued or are about to be. For these parts, seleon GmbH has researched suitable alternatives, evaluated their integration into circuit designs, and specified their usage.
Furthermore, seleon GmbH has analyzed circuit sections of legacy devices from Maquet Cardiopulmonary GmbH, replacing them with more efficient circuit designs that achieve nearly identical functionality with fewer components. This process included not only the research and selection of alternative components, but also the adaptation of circuit diagrams and the updating of PCB layouts.
The work was concluded with the commissioning and testing of the revised PCBs, including comprehensive documentation and formal acceptance by the customer.
The fully revised modules, along with all associated documentation, were handed over to the customer, who was then able to validate them in final devices and integrate them into ongoing production.
