  • Automatic release hospital thermometer
    Patent number: 4099414
    Abstract: A new arrangement for facilitating the taking of temperatures both in hospitals and in the home by simplifying the resetting of a clinical thermometer to a lower, ambient temperature after use. A plunger in the reservoir of the thermometer is magnetically actuable into a position in which it disables a restriction at which the mercury column separates to retain a reading. Several forms of this plunger are shown, and also shown is a holder for use with the thermometer to actuate the plunger.
