Abstract
We present research into the comfort of medical vehicles from the aspect of the issue of harmful effects and patient protection. A patient lying on a stretcher can receive a wide range of pre-hospital care from the medical team. Medical vehicles are produced on the basis of cargo vehicles. Their passive suspension is adapted to a truck.When moving on uneven surfaces, the vehicle's suspension causes harmful mechanical vibrations that can endanger the patient's life. By comparing the characteristics of the passive and active suspension and the simulation model, we showed the advantages of installing an air suspension to reduce and eliminate harmful vibrations. We considered a modern medical vehicle suspension, based on the principle of self-leveling of the floor height, with the possibility of lowering the rear part of the vehicle for receiving patients. On a realistic example, we have shown the possible installation of an active air suspension. The term medical suspension comes from professional jargon because it can be most closely identified with medical vehicles.
