Abstract

The present invention discloses a respiration sensor, which is attached to a testee and comprises a triaxial acceleration sensing unit, a microprocessor, and at least one alarm unit. The triaxial acceleration sensing unit detects the respiration-related movements of a testee and output a detection signal. The microprocessor connects with the triaxial acceleration sensing unit, receives the detection signal and transforms the detection signal into a respiration signal to determine the respiration state of the testee. When the respiration signal is lower than a standard, the microprocessor triggers the alarm unit to give out an alarm to alert the persons nearby.

Claims

1. A respiration sensor, attached to a body region of a testee and comprising

a triaxial acceleration sensing unit detecting body movements of said testee and outputting a detection signal;

a first microprocessor coupled to said triaxial acceleration sensing unit, receiving said detection signal, and transforming said detection signal into a respiration signal to determine a respiration state of said testee;

at least one first alarm unit coupled to said first microprocessor and triggered by said first microprocessor to give out an alarm signal when said respiration signal is lower than a standard;

a first power supply unit providing power; and

a body receiving components mentioned above.

2. The respiration sensor according to claim 1, wherein said detection signal is a voltage signal.

3. The respiration sensor according to claim 1, wherein said first alarm unit is a buzzer.

5. The respiration sensor according to claim 1, wherein said body is stuck to said testee with an adhesive tape.

6. The respiration sensor according to claim 1, wherein said body is fixed to said testee with a clip element.

7. The respiration sensor according to claim 1 further comprising a wireless transmitter arranged inside said body, coupled to said first microprocessor, and transmitting said respiration signal to a far-end receiver device to inform of a respiration state of said testee.

8. The respiration sensor according to claim 7, wherein said far-end receiver device further comprises

a wireless receiver unit receiving said respiration signal transmitted by said wireless transmitter;

a second microprocessor coupled to said wireless receiver unit and receiving said respiration signal;

at least one second alarm unit coupled to second microprocessor and triggered by said second microprocessor to give out an alarm signal when said respiration signal is lower than a standard; and

a second power supply unit providing power.

9. The respiration sensor according to claim 8, wherein said second alarm unit is an indicator.

10. The respiration sensor according to claim 8, wherein said second alarm unit is a buzzer.
