Abstract

To provide a portable biological data measuring apparatus capable of measuring, storing and displaying biological data of a human being, in particular. The apparatus includes a GND electrode (12B) and a minus electrode (12C) which are provided on the opposite side faces of a roughly rectangular parallelopiped-shaped chassis (11), and a plus electrode (12A) provided on the face curved into an elliptical arc shape in cross section and adjacent to the opposite faces on which the GND electrode (12B) and the minus electrode (12C) are provided, in which biological data is measured using the plus electrode (12A), the GND electrode (12B) and the minus electrode (12C).

Claims

1. A portable biological data measuring apparatus, comprising:

a GND electrode (12B) and a minus electrode (12C) which are provided on the opposite side faces of a roughly rectangular parallelopiped-shaped chassis (11); and

a plus electrode (12A) provided on the face adjacent to the opposite faces on which said GND electrode (12B) and said minus electrode (12C) are provided, wherein biological data is measured using said plus electrode (12A), said GND electrode (12B) and said minus electrode (12C).

2. A portable biological data measuring apparatus according to claim 1, further comprising display means (17) for displaying thereon the biological data, wherein a first R wave and a second R wave contained in an electrocardiographic waveform are displayed on said display means, and wherein an axis (17a) for reading-out of the number of heartbeats on which data representing the number of heartbeats is plotted is displayed on the axis of abscissa indicating a time base with the peak portion of the first R wave being set as a reference point.

3. A portable biological data measuring apparatus according to claim 1, further comprising display means (17) for displaying thereon the biological data, wherein an electrocardiographic waveform is displayed on said display means with the waveform being compressed in the direction of a time base.

4. A portable biological data measuring apparatus according to claim 1, further comprising display means (17) for displaying thereon the biological data, wherein the data representing the time transition of the number of heartbeats between the adjacent R waves is displayed on said display means.
