A kink is pretty important in a clinical thermometer, as it prevents the mercury level in the thermometer to fall back in the bulb, so we can take the thermometer out to measure the temperature, rather than place the thermometer in while noting down the temperature.
Kink in the Mercury thermometer helps to prevents the falling of mercury present in capillary tube into bulb. It ensures that the user takes the correct reading of temperature. That's the reason a person before taking a new reading must give a sudden shake to the clinical thermometer so that the mercury level comes to normal.
