Hospital beds are one of the most important medical devices of the 20th century. While most people wouldn’t think of hospital beds as a groundbreaking invention, these devices have emerged as some of the most useful and common items in healthcare settings. The first 3-segment, adjustable hospital beds were invented in the early 20th century by the Indiana surgeon Dr. Willis Dew Gatch. While early “Gatch beds” were adjusted via a hand crank, most modern hospital beds for sale are electric.
