Abstract

The present invention is related to a breath pacing device ( 10 ) for pacing the respiratory activity of a subject, comprising an output unit ( 12 ) for outputting a sequence of output signals, a control unit ( 16 ) provided to control the output unit, and an input unit ( 14 ) connected to or integrated into the output unit for generating an input signal related to a respiration characteristic of a subject. The control unit is provided to control the length of the sequence at least based on characteristics of the input signal. The invention is further related to a corresponding method for pacing the respiratory activity of a subject.

First claim

The invention claimed is:

1. A breath pacing device for pacing a respiratory activity of a subject, the breath pacing device comprising:
an output unit having a continuous surface without holes or apertures when assembled, the output unit configured to:
output a tactile sequence, the sequence having a length comprising a plurality of phases;

an input unit, included within the continuous surface of the output unit, configured to:
generate an input signal related to a measured respiration characteristic of a subject; and

a control unit configured to:
receive the input signal;
initiate a start signal based on one of: a determination of a respiration rate pattern associated with the input signal and a user input,
output the tactile sequence in response to the start signal; and
control the outputted tactile sequence wherein a rate of the outputted tactile sequence is gradually reduced to a predetermined value related to the determined pattern associated with the input signal and an amplitude of the outputted tactile sequence is gradually reduced from a predetermined time after the rate of the outputted tactile sequence achieves the predetermined value, said gradual reduction of amplitude preventing said outputted tactile sequence from being perceivable by the subject.

2. The breath pacing device according to claim 1 , wherein the input unit is arranged at the continuous surface of the output unit.

3. The breath pacing device according to claim 1 , wherein the input unit is configured to:
receive at least one of:
said characteristic of the subject, said characteristic being provided by one of: a sensor configured to sense the characteristic of the subject; and
a user interface configured to receive said user input.

4. The breath pacing device according to claim 3 , wherein said sensor is at least one of: a body motion sensor, a radar sensor, an accelerometer, a camera, a pressure sensor, a photoplethysmographic (PPG) sensor, an airflow sensor, and a weight sensor.

5. The breath pacing device according to claim 4 , wherein said pressure sensor comprises a pressure sensitive foil.

6. The breath pacing device according to claim 4 , wherein said airflow sensor comprises one of: a temperature sensing element and a microphone.

7. The breath pacing device according to claim 3 , wherein the user interface is at least one of: a mouse wheel, a keyboard, at least one button, a touch screen, a touch pad, a squeeze sensor, a pressure switch and a microphone.

8. The breath pacing device according to claim 3 , wherein the user interface is configured to:
perform one of: receive the user input to determine the characteristic of a subject, receive the user input to start or stop the outputted tactile sequence and output status information of the breath pacing device.

9. The breath pacing device according to claim 1 , wherein the input unit is configured to:
generate the input signal related to at least one of: a respiration frequency, a respiration amplitude, an age and an identification of the subject.

10. The breath pacing device according to claim 1 , wherein the control unit is configured to:
control the output of the outputted tactile sequence at least based on an input signal received from one of a sensor and a user interface, wherein the control is further based on one of: a previously stored characteristics and a previously stored algorithm.

11. The breath pacing device according to claim 1 , wherein the control unit is configured to:
generate a stopping signal upon receiving an input signal related to a sleeping or relaxed state of the subject after a predetermined time period has lapsed.

12. The breath pacing device according to claim 1 , wherein the output unit is at least one of: a cushion, a pillow, a pad, a stuffed toy, a wristband, a mobile phone, and a watch.

13. The breath pacing device according to claim 1 , further comprising:
at least one of: a rechargeable power supply and a temperature controlling element.

14. The breath pacing device according to claim 1 , wherein a subsequent phase comprises at least one of: a slow-down pacing phase, a constant pacing phase and a fade-out phase.

15. The breath pacing device according to claim 14 , wherein the amplitude of the outputted tactile signal is reduced to zero during the fade-out phase.

16. The breath pacing device according to claim 14 , wherein a pacing rate associated with the slow-down pacing phase comprises reducing the pacing rate from a first level to a lower second level and a pacing rate of the constant pacing phase and the fade-out phase remains at the second level.
