VOICE AND FOOTSWITCH OPERATED MEDICAL CHAIR UNIT

摘要

The present invention is a voice and footswitch operated medical chair unit wherein an operation control of the medical chair unit is executed by a speech instruction from an operator and in response to actuation of a footswitch by the operator. The chair unit has a combination of a transmitting system for detecting a speech instruction given by a sound produced from the operator and for converting the speech instruction to an electric signal and transmitting it and a receiving system for receiving the speech instruction signal; a control computer for activating the chair unit on the basis of the received signal output from the receiving system; a footswitch for executing a starting operation and a continuous control operation in response to a touch or depression made by movement of a foot of the operator; and a mechanism for executing a chair unit operation. A medical chair unit, e.g. a dental chair unit, according to the present invention dispenses with a switch operation conducted by pressing with a finger when an operator activates the medical chair unit and hence eliminates the danger of contagion or the like.
