Abstract
The present invention provides a portable guidance device for cardiopulmonary resuscitation, which comprises a tri-axial gravity sensing element, a pressure sensing element, a sound output element, a visual output element and a microcontroller. The portable guidance device for cardiopulmonary resuscitation can actively connect to the medical rescue system and issue an alarm to guide the surrounding passers-by to perform real-time rescue and perform correct cardiopulmonary resuscitation, so as to improve the efficiency and accuracy of chest compressions.
Claims17
A portable guidance device for cardiopulmonary resuscitation, comprising:
- a tri-axial gravity sensing element, which is worn on an individual to detect the tri-axial action state of the individual and output a gravity sensing signal;
- a pressure sensing element, sensing a pressing force and outputting a pressure sensing signal;
- a sound output element, generating a speech;
- a visual output element, generating a pressing depth indication or a pressing strength indication;
- and
- a microcontroller, receiving the gravity sensing signal and the pressure sensing signal;
- wherein, the microcontroller determines whether the individual has fallen based on the gravity sensing signal, and the microcontroller causes the sound output element to generate the speech for indicating a procedure of cardiopulmonary resuscitation;
- wherein, the microcontroller determines whether the pressing force matches a pressing setting based on the gravity sensing signal and the pressure sensing signal, and the microcontroller causes the visual output element response to the pressing force to generate the pressing depth indication or the pressing strength indication, and causes the sound output element response to the pressing force to generate a speech indication to meet the pressing setting in the procedure of the cardiopulmonary resuscitation.
A guidance method for cardiopulmonary resuscitation, which uses a portable guidance device for cardiopulmonary resuscitation, which comprising:
- a tri-axial gravity sensing element, a pressure sensing element and a sound output element, and the guidance method comprises steps:
- causing the sound output element to generate a speech to guide a procedure of cardiopulmonary resuscitation when a fall occurring in an individual wearing the portable guidance device for cardiopulmonary resuscitation is determined based on a gravity sensing signal of the tri-axial gravity sensing element, and the procedure of cardiopulmonary resuscitation includes placing the portable guidance device for cardiopulmonary resuscitation on the chest of the individual lying flat, and applying a pressing force on the portable guidance device for cardiopulmonary resuscitation;
- determining whether the pressing force meets a pressing depth setting value based on the gravity sensing signal, and then the sound output element generates a speech to indicate the pressing depth indication, so that the pressing force meets the pressing depth setting value;
- determining whether the pressing force meets a pressing strength setting value based on a pressure sensing signal of the pressure sensing element, and then the sound output element generates a speech to indicate the pressing strength indication, so that the pressing force meets the pressing strength setting value;
- and
- determining whether a frequency of the pressing force meets the pressing frequency setting value based on a pressing frequency sensing signal of the pressure sensing element, and then the sound output element generates a speech to indicate the pressing frequency indication, so that the frequency of the pressing force meets the pressing frequency setting value.
