Abstract

A pulse abnormality detecting device comprises a band attached to a wrist, a first sliding member with which the band is armored and which slides in the circumference direction of the band along the band, a second sliding member which is slidably provided on the first sliding member and which slides in the axis direction of the band, a pulse sensor which is provided on the second sliding member and which is provided in such a manner that the position of the sensor can be adjusted to the inner side or the side of the band, and a pulse abnormality detecting unit for detecting the abnormality of the pulse from the output data of the pulse sensor. The device can accurately detect the pulse of a user with high precision, adapting to a personal difference.

Claims

1. A pulse abnormality detection apparatus comprising:

a band adapted and configured to be worn around a wrist or an arm;

a pulse sensor positioned under an inner face of the band and/or lateral to the band;

a pulse abnormality detector for detecting a pulse abnormality from data outputted from the pulse sensor,

a first slide body that is externally attached to the band and that slides along the circumferential axis of the band; and

a second slide body positioned under an inner face of the band that is slidably provided at the first slide body,

wherein the second slide body slides laterally to the circumferential axis of the band and comprises the pulse sensor.

2. The pulse abnormality detection apparatus according to claim 1, the apparatus comprising:

a storage module for storing a standard pulse waveform and a set value by which a pulse allowable range is defined; and

a pulse abnormality recognition module for making a comparison between an output waveform, which is data outputted from the pulse sensor, and the standard pulse waveform, and for recognizing an abnormality when results of the comparison include a value falling outside the allowable range defined by the set value,

wherein the pulse abnormality detector is formed by the storage module and the pulse abnormality recognition module.

3. The pulse abnormality detection apparatus according to claim 2 further comprising:

a fixation member adapted and configured to conform to at least part of the circumference of the wrist or that of the arm or having a shape substantially conforming to at least part of a circumference of the wrist or that of the arm,

the fixation member being positioned lateral to the band and comprising a slot for accepting a tip of the second slide body, thereby fixing an optimal position of the pulse sensor in a direction generally perpendicular to the circumferential axis of the band.

4. The pulse abnormality detection apparatus according to claim 2, wherein the band comprises a main body, wherein the main body comprises the pulse abnormality detector.

5. The pulse abnormality detection apparatus according to claim 2, wherein the band comprises a transmitter, and a receiving terminal comprises the pulse abnormality detector, wherein an output waveform, which is data outputted from the pulse sensor, is transmitted to the receiving terminal via the transmitter.

6. The pulse abnormality detection apparatus according to claim 1,

wherein the second slide body has elasticity by which the pulse sensor protrudes away from the inner face of the band, or

wherein the apparatus further comprises an elastic member provided between the second slide body and the pulse sensor, thereby allowing the pulse sensor to protrude away from the inner face of the band.

7. The pulse abnormality detection apparatus according to claim 6, wherein the elastic member is a pressure sensitive diaphragm.

8. The pulse abnormality detection apparatus according to claim 6 further comprising:

a fixation member adapted and configured to conform to at least part of the circumference of the wrist or that of the arm or having a shape substantially conforming to at least part of a circumference of the wrist or that of the arm,

the fixation member being positioned lateral to the band and comprising a slot for accepting a tip of the second slide body, thereby fixing an optimal position of the pulse sensor in a direction generally perpendicular to the circumferential axis of the band.

9. The pulse abnormality detection apparatus according to claim 6, wherein the band comprises a main body, wherein the main body comprises the pulse abnormality detector.

10. The pulse abnormality detection apparatus according to claim 1 further comprising:

a fixation member adapted and configured to conform to at least part of the circumference of the wrist or that of the arm or having a shape substantially conforming to at least part of a circumference of the wrist or that of the arm,

the fixation member being positioned lateral to the band and comprising a slot for accepting a tip of the second slide body, thereby fixing an optimal position of the pulse sensor in a direction generally perpendicular to the circumferential axis of the band.

11. The pulse abnormality detection apparatus according to claim 1, wherein the band comprises a main body, wherein the main body comprises the pulse abnormality detector.

12. The pulse abnormality detection apparatus according to claim 1, wherein the band comprises a transmitter, and a receiving terminal comprises the pulse abnormality detector, wherein an output waveform, which is data outputted from the pulse sensor, is transmitted to the receiving terminal via the transmitter.

13. The pulse abnormality detection apparatus according to claim 12, wherein the transmitter is a connection line.

14. The pulse abnormality detection apparatus according to claim 5, wherein the transmitter is a connection line.

15. The pulse abnormality detection apparatus according to claim 1, wherein the band comprises a temperature sensor or an air pressure sensor.
