Abstract
A toy for a pseudo-medical kit, such as a make-believe reflex hammer, stethoscope, thermometer, sphygmomanometer or syringe, has a nonfunctional mobile part which resembles a functional element of the instrument simulated thereby and whose displacement or deformation produces a perceptible indication, such as the lighting of a lamp, a whistling sound, or the display or a numerical or pictorial reading.
