Problems solved by technology

[0007] However, since the electrodes 301 and 302 of the conventional heart rate meter are large in size, the radio wave signal output by the antenna 306 is absorbed by the electrode 301, which poses a problem that the efficiency of transmission using radio waves decreases.
[0008] Important information measuring devices other than heart rate meters having a configuration including an antenna for transmitting data and electrodes for detecting important information also suffer from the problem that the efficiency of data transmission using radio waves decreases as described above

Embodiment Construction

[0028] FIG. 1 is a block diagram of a vital information detecting device according to a mode of carrying out the present invention, showing an example of a heart rate meter applied by being attached to a user's body.

[0029] Fig. 2 is a front view of the important information detection device shown in Fig. 1, and parts consistent with Fig. 1 are denoted by the same reference numerals.

[0030] In FIGS. 1 and 2, the heart rate meter has a pair of electrodes for detecting heartbeat as important information detecting means (electrode 101 is on the positive side, electrode 102 is on the negative side (ground side)), an inductor 103 is used as a suppressing means, The communication circuit 104 functions as a communication device and an antenna 110 .

[0031] The inductor 103 , the communication circuit 104 and the antenna 110 are housed within the housing 201 . The electrodes 101 and 102 are mounted on the case 201 such that they are exposed outside the case 201 to allow them to ...

Abstract

Degradation of the efficiency of data transmission using a radio wave is to be suppressed. A communication circuit transmits heart beat information detected by electrodes to a master apparatus through an antenna using a radio wave. An inductor provided between the electrodes and an input section of the communication circuit suppresses input of the radio wave output by the antenna to the communication circuit through the electrode and waste of the same.

Description

technical field [0001] The present invention relates to an important information measuring device that detects important information such as a heartbeat and transmits the information using radio waves. Background technique [0002] As an important information measuring device, a heart rate meter has been used which is attached to a human body for measuring a heartbeat and transmits the measured heartbeat data through an antenna radio. [0003] Fig. 3 is a block diagram of a conventional heart rate meter. This heart rate meter has a pair of electrodes (electrode 301 on the positive side, electrode 302 on the negative side (ground side)) for detecting heartbeat, a heartbeat detection circuit 303, a central processing unit (CPU) 304, a radio frequency (RF) circuit 305, and antenna 306. [0004] The electrode 302 is grounded, and the electrode 301 is an electrode for electrically detecting and extracting the heartbeat of the human body. The heartbeat detection circuit 303 det...
