Abstract

A method and device (10) are provided for monitoring regular movement of a human body (34), such as an infant'"'"'s body. The method includes attaching the device (10) to the body (34) with a protuberance (24) of the body in abutment with the body, so that the protuberance is deflected as the body moves regularly. The deflection of the protuberance (24) is monitored and an alarm (18,19,20,52) is activated if the pattern of deflection of the protuberance changes to a predetermined extent, e.g. if it is disrupted.

Claims

1. A device for monitoring regular breathing movement of the body of an infant, said device comprising:

an electronic circuitry including at least one alarm; and

an attachment means for releasably attaching the device to the infant body in the anterior abdominal region;

characterised in that said device includes a resiliently flexible protuberance extending from the device; and

a transducer connected to the electronic circuitry and extended inside said protuberance to detect deflection of the protuberance;

said attachment means and protuberance being configured such that the protuberance abuts the body of the infant in the anterior abdominal region when the device is attached to the infant body in the anterior abdominal region and said electronic circuitry being configured to activate the alarm in an event that a pattern of the detected deflection of the protuberance changes to a predetermined extent.

2. The device as claimed in claim 1, characterised in that said device includes at least one sensor configured to monitor a condition, said electronic circuitry being configured to activate said alarm in the event that a predetermined event is detected by the at least one sensor.

3. The device as claimed in claim 2, characterised in that said at least one sensor includes a sensor selected from a temperature sensor, a humidity sensor and a microphone.

4. The device as claimed in claim 1, characterised in that said attachment means includes a clip that is attachable to an article of clothing of the infant.

5. The device as claimed in claim 4, characterised in that said protuberance extends from any part of the device towards the side on which the clip is disposed in a direction such that said protuberance abuts the body of the infant in the anterior abdominal region, in use.

6. The device as claimed in claim 1, characterised in that said electronic circuitry includes the alarm that is configured to cause at least a part of the device to vibrate.

7. The device as claimed in claim 1, characterised in that said electronic circuitry includes the alarm that is configured to emit sound.

8. The device as claimed in claim 1, characterised in that said electronic circuitry includes the alarm that is configured to emit light.

9. The device as claimed in claim 1, characterised in that said electronic circuitry includes the alarm that is configured to transmit a signal to another device, upon being activated.

10. The device as claimed in claim 2, characterised in that said attachment means includes a clip that is attachable to an article of clothing of the infant.

11. The device as claimed in claim 2, characterised in that said electronic circuitry includes the alarm that is configured to cause at least a part of the device to vibrate.

12. A method of monitoring regular breathing movement of the body of an infant, said method including:

releasably attaching a monitoring device to the infant body in the anterior abdominal region, with a protuberance of the device in abutting contact with the body of the infant in the anterior abdominal region;

characterised by allowing regular movement of the infant body in the anterior abdominal region relative to the monitoring device to be transferred to the protuberance, causing the protuberance to deflect; and

activating an alarm of the monitoring device if a pattern of deflection of the protuberance changes to a predetermined extent;

wherein the monitoring device comprises a transducer connected an electronic circuitry and extended inside the protuberance to detect the pattern of deflection of the protuberance.

13. The method as claimed in claim 12, characterised by keeping said protuberance in abutment with the body of the infant in the anterior abdominal region.

14. The method as claimed in claim 12, characterised by keeping said protuberance generally in continuous contact with the infant'"'"'s skin.

15. The method as claimed in claim 12, characterised in that said change in the pattern of deflection is that an interval between successive deflections of the protuberance exceeds a predetermined maximum period.

16. The method as claimed in claim 12, characterised in that said change in the pattern of deflection is that an interval between successive deflections of the protuberance is shorter than a predetermined minimum period.

17. The method as claimed in claim 12, characterised in that said method includes monitoring at least one condition of said infant selected from the infant'"'"'s heartbeat, the infant'"'"'s body temperature, crying, and humidity of said infant'"'"'s environment, and said method includes activating the alarm in a predetermined event is detected in said monitored condition.

18. The method as claimed in claim 12, characterised in that said attachment of the monitoring device to the infant'"'"'s body includes attaching the monitoring device to an article of clothing of the infant.

19. The method as claimed in claim 12, characterised in that said alarm includes at least one of a tactile alarm, an audible alarm, a visible alarm, a transmission of a signal to a remote device, or a display.
