Abstract
A thermoelectric diagnostic instrument including a housing, a thermocouple device in the housing and thermoconductor means for delivering heat and cold from the thermocouple device to contact elements located externally of the housing. Heat dissipating means including a heat sink for receiving excess heat from the thermocouple device and means for directing ambient air into engagement with the heat sink is also located in said housing.
Claims12
A thermoelectric diagnostic instrument comprising:
- a housing defining an interior;
- a thermocouple device mounted in said housing and having a plurality of junction plates;
- means for selectively inducing an electrical current in said thermocouple device to actuate said thermocouple device whereby at least one junction plate is cooled and at least one junction plate is heated;
- separate thermoconductor elements extending from each of said heated and cooled plates to separate contact elements being adapted for selective contact with a patient;
- and
- means in said housing for dissipating excess heat generated by said thermocouple device, said heat dissipating means comprising heat sink means positioned in said housing interior and operatively connected to said heated plate and the thermoconductor element extending from said heated plate.

A thermoelectric diagnostic instrument comprising:
- a housing defining an interior;
- Peltier module means of unitary construction in said housing and having hot and cold junction plates;
- a thermoconductor element in operative engagement with each of said plates for transmitting heat and cold to contact elements spaced from said plates and disposed external of said housing;
- heat sink means positioned in said housing interior for dissipating heat generated by said Peltier module means and operatively connected to said hot plate and the thermoconductor element in operative engagement with said hot plate to draw heat therefrom;
- and
- means in said housing interior for directing a flow of air past said heat sink means and out of said housing.

A thermoelectric diagnostic instrument comprising:
- a housing defining an interior and including a cap member selectively removably connected to the rest of said housing;
- a Peltier module positioned in said housing interior and having hot and cold junction plates;
- a heat sink;
- elongated thermoconductor elements positioned in spaced relationship in said cap member and extending from said Peltier module to a location remote therefrom, one of said elongated thermoconductor elements being operatively connected to said hot junction plate and said heat sink and the other of said elongated thermoconductor elements being operatively connected to said cold junction plate;
- and
- contact elements located at the ends of said elongated thermoconductor elements remote from said Peltier module means and projecting outwardly from said cap member at spaced locations thereon.
