Abstract

A heartbeat detection device includes a pair of electrode units, a transmitting unit and a receiving unit. The transmitting unit is electrically connected to the paired electrode units each by respective wires. The paired electrode units each include an electrode body and a hook sandwiching a bottom part of a garment for example on a body for holding the electrode units on respective predetermined parts of the body. The hook is formed on the front side of the electrode unit. The transmitting unit includes a transmitting-unit body and a hook sandwiching an upper part of the garment for holding the transmitting unit on the garment. The hook is formed on the rear side of the transmitting unit. The lightweight heartbeat detection device is thus achieved that can ensure electrical contact between the electrode units and respective predetermined parts of the chest without causing a feeling of tightness.

Claims

1. A heartbeat detection device comprising:

a pair of electrode units electrically contacting predetermined parts respectively of a body for detecting an electric potential concerning heartbeat;

a first clipping unit provided to each of said paired electrode units for sandwiching an article worn by the body for holding said paired electrode units on respective predetermined parts of the body;

a transmitting unit for transmitting, as a heartbeat signal, information about the electric potential detected by said paired electrode units;

a wire connecting said paired electrode units each with said transmitting unit; and

a receiving unit receiving the heartbeat signal transmitted from said transmitting unit.

2. The heartbeat detection device according to claim 1, wherein

said paired electrode units each include

an electrode body electrically contacting a predetermined part of the body,

a hook provided on a side of the electrode unit that is opposite to a side thereof which faces the body and on which said electrode body is provided, and

said electrode body and said hook serve as said first clipping unit for clipping from underneath the article worn by the body.

3. The heartbeat detection device according to claim 2, further comprising:

an attachment belt serving as the article worn by the body; and

a hook-inserted portion provided in said attachment belt for receiving said hook of said first clipping unit to catch said paired electrode units each by said attachment belt.

4. The heartbeat detection device according to claim 1, wherein

said paired electrode units each include projections provided on a side of the electrode unit that faces the body.

5. The heartbeat detection device according to claim 1, wherein

said transmitting unit includes a second clipping unit for clipping from above the article worn by the body.

6. The heartbeat detection device according to claim 5, wherein

said second clipping unit has a function of catching a ring-shaped cord suspended from neck.
