Disposable sheath in combination with a clinical probe, the sheath, comprising a frame defining an aperture large enough to admit the probe and an elastic membrane fixed to the frame and covering the aperture, so that upon a forceable insertion of the probe through the aperture the membrane will stretch by at least 100 percent along the probe axis to conform to the probe surface to be sheathed. The probe includes inner spring-biased retainers that hold the sheath on the probe by said frame, with a movable actuator that ejects the sheath from the probe upon actuation.
