Abstract

A pulse measuring apparatus comprises a pulse sensor unit having a pulse sensor, a pulse measuring instrument having a display section for displaying a pulse number, and an arm wearing band fixed to the pulse measuring instrument and to which the pulse sensor unit is attached so as to be capable of adjusting its position in a longitudinal direction. A radio transmission section is disposed in the pulse sensor unit and a radio reception section is disposed in the measuring instrument, whereby data can be radio-transmitted from the pulse sensor unit to the measuring instrument. The data to be radio-transmitted is a pulse detection signal of the pulse sensor of the pulse sensor unit, or a pulse number obtained by calculation-processing the pulse detection signal by a signal processing section of the pulse sensor unit.

Claims

1. A pulse measuring apparatus comprising:

a pulse sensor unit in which a pulse sensor has been accommodated in a sensor housing;

a pulse measuring instrument at least possessing a display section displaying a pulse number; and

an arm wearing band which has been fixed to the pulse measuring instrument and to which the pulse sensor unit has been attached so as to be capable of adjusting its position in a longitudinal direction characterized in that a radio transmission section has been possessed in the pulse sensor unit and a radio reception section in the pulse measuring instrument, respectively.

2. A pulse measuring apparatus according to claim 1;

wherein the pulse sensor unit is one which transmits a pulse detection signal of the pulse sensor, and the pulse measuring instrument is one which receives the pulse detection signal by the radio reception section and calculation-processes it to a pulse number by its signal processing section, thereby displaying the pulse number by the display section.

3. A pulse measuring apparatus according to claim 1;

wherein the pulse sensor unit is one which calculation-processes a pulse detection signal of the pulse sensor to a pulse number by its signal processing section to thereby transmit the pulse number from the radio transmission section, and the pulse measuring instrument is one which receives the pulse number by the radio reception section, thereby displaying it by the display section.

4. A pulse measuring apparatus according to claim 1;

wherein a power source of the pulse sensor unit is a battery having been accommodated in the sensor housing.

5. A pulse measuring apparatus according to claim 1;

wherein a drive voltage is supplied to the pulse sensor by a wiring for power source, which has been provided in the band, from a battery accommodated in a measuring instrument case.

6. A pulse measuring apparatus according to claim 5, wherein the wiring for power source is one pair of embedded lines having exposure parts which have been partially exposed in an attaching position of the pulse sensor unit, and movable power source terminals of the pulse sensor unit are disposed so as to electrically contact with the exposure parts of the wiring for power source.

7. A pulse measuring apparatus according to claim 6, wherein the attaching position of the pulse sensor unit is a slit having been formed in the band, and the wiring for power source has the exposure parts in bottom faces of concave parts for position adjustment, which are formed in both sides of the slit in a longitudinal direction.

8. A pulse measuring apparatus according to claim 6;

wherein the movable power source terminals of the pulse sensor unit are constituted by one pair of electrically conductive connection pins and one pair of electrically conductive pressurized springs, which have been disposed in the sensor housing.

9. A pulse measuring apparatus according to claim 1;

wherein there has been provided an input means which instructs a starting and a stopping of a pulse detection to the pulse sensor unit.
