Abstract

Disclosed is a device for confirming recycle of a disposable medical handpiece, which can prevent imprudent recycle of the medical handpiece that should be discarded after one time. The device includes a signal conversion unit which receives DC power from the handpiece and detects voltage applied to a driving motor of the handpiece to convert the voltage into a rated signal and output the rated signal; a control unit which receives the output signal of the signal conversion unit, detects an initial operation state of the driving motor based on the output signal and then outputs a lamp switching signal when the driving motor is operated again after a predetermined operation interval is elapsed; and a lamp which is connected with an output terminal of the control unit and turned on in response to the lamp conversion signal.

Claims

1. A device for conforming recycle of a disposable medical handpiece, which alarms recycle state of a disposable medical handpiece (100), wherein the device comprises:

a signal conversion unit (303) which receives DC power from the handpiece and detects voltage applied to a driving motor of the handpiece (100) to convert the voltage into a rated signal and output the rated signal;

a control unit (301) which receives the output signal of the signal conversion unit (303), detects an initial operation state of the driving motor based on the output signal and then outputs a lamp conversion signal when the driving motor is operated again after a predetermined operation interval (Δ

t) is elapsed; and

a lamp (L) which is connected with an output terminal of the control unit (301) and turned on in response to the lamp switching signal, and is provided in an inside of the handpiece (100).

2. The device of claim 1, wherein the control unit (301) has an internal counter and carries out decision for the interval by the internal counter based on a cell battery that stores a predetermined electric capacity.

3. The device of claim 1, the signal conversion unit (303) is any one of an analogue/digital (A/D) converter that converts the operating voltage of the driving motor into a digital signal, and a zener diode or a regulator for recognizing the operation voltage of the driving motor as a set constant voltage.

4. The device of claim 1, wherein the lamp (L) is a light emitting diode (LED), and the LED is lit in a green color when the driving motor is initially operated and is lit in a red color when the driving motor is operated again after the predetermined operation interval (Δ

t) is elapsed.

5. The device of claims 1, wherein the handpiece (100) is attached at an upper end thereof with a submersion sticker (110) for detecting whether the handpiece (100) has been in contact with water.

6. The device of claims 1, wherein the handpiece (100) further includes a sound output unit that outputs a predetermined sound in response to the lamp switching signal.

7. The device of claim 6, wherein the sound output unit is a buzzer or a piezoelectric speaker.
