1. Device for assessing thermoalgesic and vibratory sensitivity, comprising:
a first unit configured to apply to localized points of a patient a plurality of stimuli comprising vibrations and temperature changes,
a second unit for communicating with the first unit via wireless transmission,
wherein the first unit comprises:
an outer casing,a tuning fork that has two arms converging on a central point for applying vibration and a Peltier cell with ventilators for generating cold-heat to apply a plurality of stimuli to localized points of the patient body,an ejecting arm adapted to move respect to the outer casing in order to deploy the Peltier cell with ventilators, andan electrical circuit adapted to vary the intensity of the plurality of stimuli comprising the vibration from the tuning fork and the cold-heat from the Peltier cell,
wherein the ventilators are configured to rotate around an axis perpendicular to an axis of the outer casing,
wherein the ejecting arm is disposed parallel to said axis and is connected to the outer casing to move with respect to the outer casing according to a direction parallel to the axis, in such a way that when the ejecting arm is:
in a deployed position, the ejecting arm and the Peltier cell with ventilators project from the outer casing and the Peltier cell with ventilators is configured to adopt an inclination with respect to the axis of the outer casing and with respect to an angle of the Peltier cell with ventilators when the ejecting arm is in a retracted position;
wherein the second unit comprises:
a power button, and
two buttons for the input of data to operate the tuning fork that has two arms and the Peltier with ventilators,
an indicator for indicating different operational stages of the first unit, and
wherein the device is adapted to execute a quantification programme to quantify a response capacity of the patient to the plurality of stimuli,
wherein said response capacity is based on a score derived from a group of responses to the plurality of stimuli;
wherein the response capacity is affirmative when at least one of the plurality of stimuli is detected by the patient or negative when the at least one of the plurality of stimuli is not detected by the patient,
wherein the first and second units are configured to implement a self-test after
the first and second units are turned on, said self-test comprising an assessment of a battery charge, an ambient temperature, a skin temperature, a radiofrequency or infrared communication status,
wherein the first and second units are configured to be powered electrically and autonomously,
wherein the outer casing comprises a rubber washer on a tip of the outer casing,
wherein a piezo-electrical element of 125 to 248 Hz or a speaker with coil
for generating the vibrations is fixed to a free end of each of the two arms of the tuning fork.
