Abstract
Accordingly, the object of the present invention is to provide a pulse meter comprising a pen body installed with a counting microprocessor, and a liquid crystal display (LCD) and a counter are installed on the proper position of the pen body. The counting microprocessor is connected with the LCD and the counting key. One hand may press a tested person or a patient for sensing the beat of the pulse thereof, and the other hand serves to press a counting key to count the times of the pulse, and thus the frequency of the pulse can be input into the counting microprocessor. Next, the counting microprocessor can derive the pulse number per minute and then display the result in the LCD. Since only a short period of pulse beat is necessary to be input the counting microprocessor. Thus the pulse frequency can be derived in a very short time and much time is saved. A switching key and time adjusting key are installed on the pen body, thus the counting microprocessor can be switched to a time display mode by the switching key. Thus, when the pulse meter is not used, it can be used as a clock for showing time.
