MediVac Vacuum Former designed specifically for hospitals
Ridat MediVac series of vacuum formers offers a choice of sizes depending on whether shells were to be made to fit the head and neck or to fit the thorax.
It was first developed in early 70's, in co-operation with Royal Marsden Hospital, London to produce beam directional shells for radiotherapy.
Despite being messier than the thermoplastic option, vacuum formed shells are generally more accurate, better in replicating the contours of the body, less flimsy, easier to label and more suitable for skin sparing.
