Abstract:This bachelor assignment researches the possibility of the development of a transport container which can be transformed into an operating room during natural disasters. This assignment will be focused on the development of the construction rather than the medical part. This paper starts with an analysis of the point of view from the company that offered the assignment, Holland Medical Services. This resulted in the demand that the container must be able to be transported through the air and that on location the container can be transformed into an operation room with a surface of at least 24 m2. Besides these operation rooms there will also be tents to complete the mobile hospital, the entire hospital must be operating within eight hours after dropping the complex. The complex must also be transportable over water and land. The healthcare provided in the mobile hospital should be equal to the healthcare that is available in the country where the natural disaster took place. This means that the operation rooms are obligated to maintain certain climatic conditions, like temperature, humidity and an overpressure of minimal 1,05 Pascal. The analysis made clear that there have to be ISOcorners in the design of the container to be able to fulfill the demands of water and air transport. Furthermore, attention should be paid to aftershock and the protection against it because the chances on an aftershock are high in the first 24 hours after the earthquake. With the information that has been gathered a future scenario has been written in which the different phases of use have been described. After some interviews with Holland Medical Services it became clear that there were some contradictions in the demands of the company, these contradictions have been discussed with Holland Medical Services and choices have been made between the use of one of multiple materials, costs versus weight and the choice of design. These choices together with all the other demands have been merged into a list of requirements. The requirements have been divided in functions, criteria and issues. Based on a morphologic schedule three different concepts have been made. The seven functions that have been elaborated in the idea generation are: the volume expansion, the placement of the legs, the way the legs expand, prevention of leakage, the isolation of the operation room, leveling the operation room and the protection against aftershocks. The three concepts use different solutions to these functions; the concepts are named Slide, Harmonica and Railaway. After the idea generation these three concepts have been developed to give more detailed interpretation to the functions and they have been evaluated and the best concept have been chosen to be optimized. Concept Slide has been chosen, the concept uses a hydraulic system to expand the legs and during transport the legs are stored in the chassis of the container. For increasing the volume the container uses a slidemechanism en and an automatic controls the leveling of the operation room. The isolating is done by putting insulation between the walls of the operation room. To prevent damage from an aftershock a damper system will be placed between the operation room and the chassis, this way the operation room can freely move in the horizontal plane. A tube will be placed in the walls to prevent leakages and unwanted airflow through the seams, the tube will be inflated after the expansion of the container. After choosing the concept the detailing could begin, in this part attention has been paid to the frame, the water basin, emergency exits, the driving of the slidesystem, materials, cables and the connection to the tents complex. After detailing all these points an estimation of the weight of the transport container has been made. Concluding it can be said that it is technically possible to develop a container that can be transformed into an operation room however due to the weight it is still uncertain if the limit of 4000 kg is feasible. In order to get some clarity on this issue a optimizations of the frame has to been done, furthermore it is important to get in touch with companies that provide more detailed information on the materials and the solutions that have been chosen.
