What is the function of Kink in a clinical thermometer?

A kink or constriction in a clinical thermometer plays an important role. It prevents the rapid falling of the mercury back into the bulb of the thermometer after it is removed from the mouth or any place it is held to record the temperature. Hence we can measure the temperature of the body accurately and conveniently even if the thermometer is taken out from the body.
