Abstract
A device for evaluation of suicide risk of a person. A measuring unit measures electrodermal activity in fingers of the person to detect depressed persons who are at risk for suicide. The measuring unit is arranged to transmit a sound signal or tone to the person and to provide a signal for analysis of the electrodermal activity from the person. A measuring module measures orientation reactions in the form of blood volume variations of the person, preferably by a phtophletysmographic method peripherally in the fingers and/or centrally in the frontal lobe of the brain through the forehead, and changes in the pulse rate of the test person.
Claims19
A device for use in an evaluation of suicide risk of a person, the device comprising:
- a first measuring unit that measures electrodermal activity in fingers of the person to be evaluated to detect a depressed person who is at risk for suicide, wherein the first measuring unit is configured to emit and transmit a sound signal or tone to the person to be evaluated and to generate an electrodermal response signal for analysis of the electrodermal activity from the person to be evaluated;
- a second measuring unit configured to measure orientation reactions on sound stimuli from said sound signal or tone, the orientation reactions comprising blood volume variations of the person to be evaluated;
- and
- at least one microphone configured to detect noise interference, wherein microphone signals are transmitted in parallel with the electrodermal response signal to be included in the signal analysis, and
- wherein the sound signal or tone is repeated in a predetermined interval according to a specific schedule.
A method for evaluating suicide risk of a person, the method comprising:
- measuring, by a first measuring unit, electrodermal activity in fingers of the person to be evaluated to detect a depressed person who is at risk for suicide;
- transmitting, by first measuring unit, a sound signal or tone to the person to be evaluated and generating an electrodermal response signal by a first measuring unit for analysis of the electrodermal activity from the person to be evaluated;
- measuring, by a second measuring unit, orientation reactions on sound stimuli from the sound signal or tone, the measuring comprising measuring blood volume variations of the person to be evaluated;
- and
- detecting noise interference by at least one microphone, wherein microphone signals are transmitted in parallel with the electrodermal response signal to be included in the signal analysis,
- wherein the sound signal or tone is repeated in a predetermined interval according to a specific schedule.
