The collecting and processing assembly 101 collects a corresponding physiological index signal in response to a physiological index collection instruction sent by the intelligent terminal 2, and analyzes and processes the physiological index signal to obtain a corresponding physiological index data, and sends the physiological index data to the intelligent terminal 2; in which, the physiological index signal includes electrodermal signal, heart rate signal and blood oxygen signal.
The intelligent terminal 2 is configured to receive and display a physiological index data. In which, the intelligent terminal 2 can be a mobile intelligent terminal, such as a mobile phone, a tablet PC and so on, and also can be a computer terminal.
In the above embodiments, when monitoring a physiological index, the device body 1 is fixed at the user’s ear by using the fixing piece, and the user can send the physiological index collection instruction with the intelligent terminal 2. The collecting and processing assembly 101 at the device body 1 collects the corresponding physiological index signal in response to the physiological index collection instruction, and analyses and processes the corresponding physiological index signal to obtain the physiological index data, and sends the physiological index data to the intelligent terminal 2. The user can view their own physiological index data with the intelligent terminal 2. Compared with a common physiological index detection device, the device provided in the present application is smaller and convenient to carry, and integrates multiple physiological indices. By wearing the device at the human ear, the physiological indices of a human can be monitored, so that the user can obtain information about their own multiple physiological indices in real time, so as to realize real-time monitoring of physiological health condition and improve a user experience.
In order to reduce an occurrence of a situation that the physiological index signal cannot be collected or is collected inaccurately caused by an earlobe clip 11 slips, as a further embodiment of the collecting and processing assembly 101, the collecting and processing assembly 101 also is configured to determine whether the blood oxygen signal or heart rate signal is obtained. If yes, a wearing state normal signal is output; if no, a collection is stopped and a wearing state abnormal signal is output.
In the above embodiments, during monitoring, if the collecting and processing assembly 101 can obtain the blood oxygen signal or heart rate signal normally, it can be determined that a wearing state is normal; if the blood oxygen signal or heart rate signal cannot be obtained, it may be that the device body 1 is not fixed well or is removed, so that it can be determined that the wearing state is abnormal, and the collection should be stopped, so as to know the wearing state of the device body 1 in real time and stop monitoring after removed from the ear.

Referring to
In the above embodiments, the device body 1 is clamped at the earlobe part of the human ear by using the earlobe clip 11, which reduce an occurrence of a situation that the device body 1 slips off when wearing by the user, and improve a stability when monitoring the physiological indices.
Referring to
The electrodermal signal collection unit is configured to collect an electrodermal signal of a shoulder and a back of the human body, and the red light emitter 1011 and the infrared light emitter 1012 are provided at an inner side of a clip body at one side of the earlobe clip 11, and the photoelectric sensor 1013 is provided at the inner side of the clip body at another side of the earlobe clip 11. The photoelectric sensor 1013 is configured to receive a light beam emitted by the infrared light emitter 1012 and the red light emitter 1011 transmitting through the earlobe to collect the heart rate signal and/or blood oxygen signal. In which, the electrodermal signal collection unit includes two electrodermal signal collection buckles 1014 for collecting the electrodermal signal of the shoulder and the back, which can be connected with the device body 1 by using the electrodermal signal detection line.
The processing module is configured to analyze and process the physiological index signal to obtain the corresponding physiological index data. In which, the processing module can be CPU processor, single chip and so on.
In the above embodiment, the electrodermal signal of the shoulder and the back of the human is collected by using the electrodermal signal collection unit, and the clip bodies at both sides of the earlobe clip 11 completely covers the earlobe of the human ear. The heart rate signal is collected by turning on the red light emitter 1011 separately to emit a red light, and the blood oxygen signal is collected by turning on the red light emitter 1011 and the infrared light emitter 1012 at the same time, so as to obtain the multiple physiological index data of the human.
Specifically, when collecting the heart rate data, the red light emitter 1011 is turned on, and the red light transmits through a skin and a degree of light loss is transferred to the photoelectric sensor 1013. Because there are abundant capillaries in the earlobe, with a flow of blood in an artery, an absorption ability to the red light also changes. At this time, the photoelectric sensor 1013 converts changes of received different light intensities into current signals, and the obtained current signals can be divided in to DC signal and AC signal. The AC signal is extracted, which can reflect a characteristic of a blood flow, thus a heart rate signal data can be obtained.
When collecting the blood oxygen signal, the infrared light and the red light can be emitted at the same time. Because there is a certain ratio of oxyhemoglobin HbO2 to hemoglobin Hb in the blood, it is needed to emit the red light and the infrared light alternately at a certain frequency. The oxyhemoglobin HbO2 has the stronger absorption ability to the red light, while the hemoglobin Hb has the stronger absorption ability to the infrared light. By calculating the ratio of an absorption amount of the oxyhemoglobin HbO2 to the red light to an absorption amount of the hemoglobin Hb to the infrared light, a blood oxygen signal data can be obtained.
As the further embodiment of the collecting and processing assembly 101, the collecting and processing assembly 101 further includes an acceleration sensor, which is configured to collect an acceleration value generated during motion of the human and send the acceleration value to the processing module. The processing module also is configured to determine whether the acceleration value is higher than a preset threshold, and mark a time period when the acceleration value is higher than the preset threshold as a motion period.
In which, the acceleration sensor can be a three axis acceleration sensor or other types of acceleration sensor. By providing the acceleration sensor at the device body 1, the acceleration value of the user can be effectively collected.
In the above embodiments, the acceleration value generated by the human during motion is collected by using the acceleration sensor. When the acceleration value is higher than the preset threshold, this period is marked as the motion period by using the processing module, so as to know the corresponding physiological index data when the human is in the motion period.

In this embodiment, the green light emitter is provided at the same side as the red light emitter 1011.
In the above embodiments, when the human is in motion, the collection of the blood oxygen signal and/or the heart rate signal can be disturbed by an ambient light. Thus, when the acceleration value collected by the acceleration sensor reaches the preset threshold, the green light emitter is turned on to emit a green light to inhibit the ambient light around the earlobe clip 11, so that an accuracy when collecting the blood oxygen signal and/or the heart rate signal is improved; when the acceleration value is not higher than the preset threshold, the green light emitter will not be turned on.
