In medicine for testing the vitality of nerve tissue by measuring or irritating.

BACKGROUND OF THE INVENTION:

The vitality tests used so far are handheld instruments for testing living or dead teeth.the stored batteries are used in the transistor inverter.to produce higher AC voltage and current intensity control is performed in the secondary outlet with a potentiometer, or electrical and new transformation.Test vitality is performed by applying an active electrode to the tooth to be tested and the second pole of current connected to the metal casing is passed through the attending physician by touching the patient to close the electrical circuit.In case it is used to regulate the potentiometer intensity, the losses must be replaced by a stronger source. Current intensity to test tooth vitality, electrical path, and new transformation requires an increased number of batteries. Especially dangerous to perform high voltage current transformation when using 200 Volts at a low frequency below 100 Hz. Apparatus using an increasing intensity for timing adjustment is at risk if the doctor failed to close the circuit imperfectly at the start of the procedure and applied the electrode later at the highest level of automatically generated voltage. All these devices cannot be used for sterile treatment or rubber gloves. Also, they cannot be washed and sterilized by boiling.

Vitalitest with double electrode for sterilization is made as a handheld device for physicians to test or irritate living nerve tissue, which can be washed and sterilized without damage up to 120 ° C and also work with this device in rubber gloves. The inserted batteries power the hermetically encapsulated plastic transistor inverter, which produces 40 Volt harmless high frequency AC high frequency in the upper band of acoustic oscillations that reduce the resistance of hard tissue.This voltage is produced from a separate winding of the inverter transformer and is not attenuated or otherwise, saving battery or number. Saving the battery also helps to regulate the intensity of the current through the resistors, while eliminating the risk of injury by the test current. The advantage is also easy to replace the battery without screwing and simple regulation of the test current intensity by turning the bayonet lock.

FIG. 1 shows a tubular metal handle 1 in which the battery 2 is housed and on the upper part at the insertion point of the second part there is a bayonet closure 3 with a current switch 4.

In FIG. an extruded rigid part is shown in which a hermetically encapsulated transistor inverter 2 in plastic 2 with a groove with collector surfaces 6 for current switching and a light-emitting diode A for optical control of the switched-on current is embedded. In order to secure the connection and the part in FIG. 1, the groove also serves to rotate the bayonet closure which simultaneously adjusts the intensity of the test current by turning.

In FIG. is schematically indicated the electrical wiring in the test where the current from the battery 2 leads to the collector surfaces, 6 through the resistors leads to the transistor inverter? With a light-emitting diode 6 connected. A separate winding on the transistor inverter 2 directs the alternating voltage directly to the rotating test tips 8.

On držadle.1 tubular metal with a battery 2 is constructed on the edge of a bayonet closure to the switch current £ 4.do tubular handle 1 is inserted in a suitably shaped body made of plastic, in which is hermetically encapsulated transistorized inverter 2 ³ bayonet lock groove 9 which The current switch 4 fits into the groove of the collector surfaces 6. The control resistors are connected to the collector surface 6, before entering the inverter 2, ^{3 of the} Poiu with a light emitting diode?. A separate 40 V high voltage AC winding is wound on the inverter transformer and is routed unmuted to the test leads 8.

Claims (1)

PATENT CLAIMS. Vitalitest with double electrode for sterilization as a hand held device with its own current source, for testing of living nerve tissue, performed without damage with necessary regulation of the intensity of the test current, made for working with rubber gloves, washing and sterilization up to 120 ° 0 of living nerve tissue uses 40 Volt high frequency AC voltage in the upper acoustic frequency band, led directly to the test tips (8), from a separate winding on a transformer encapsulated hermetically encapsulated plastic transistor inverter (5) with a control device in the primary current through resistors connected to the collector surfaces (6) in which the current switch (4) switches the battery current (2), embedded in the tubular metal handle (1), secured by the bayonet closure (3) and the part (5) in the bayonet closure rotation groove / 9 /, which also serves after by turning to control the current intensity control, and by checking the LED (7).
