The present disclosure generally relates to a health care system and, more particularly, to a health care system with long-distance data access that determines whether a physiological signal is abnormal through data comparison.
Due to the growing health consciousness, people are more and more concerned about their health management. In the health self-management, it is very important to keep a track on the daily body condition in order to find out any potential disease at the early stage. This can prevent worsening of the illness condition.
To observe the daily body condition, a health management device is usually used. In general, the health management device includes a display and a physiological sensor. When the user wears the physiological sensor on a certain part of the body, the physiological sensor can detect the physiological signal of the user. The detected physiological signal is transmitted to the display in order to inform the user of his/her physiological condition, including the body temperature, the pulse or the blood pressure.
A conventional health management device is usually not able to determine whether the physiological signal is abnormal or not. Therefore, such a health management device is not able to remind the user of the abnormality of the physiological signal. Although the user can know about his/her body temperature, the pulse or the blood pressure through the health management device, the user is still unable to realize whether his/her body condition is abnormal. Besides, different users have different physiological signals when they are in a healthy condition. Based on this, although the health management device can detect the abnormality of the physiological signal, the health management device is still unable to accurately determine the abnormality of the physiological condition of the user since the health management device has only a single type of reference data for comparison. As a disadvantage, the performance of the conventional health management device is low.
In light of this, it is necessary to provide a health care system that has a high performance.
It is therefore the objective of this disclosure to provide a health care system capable of comparing the physiological waveform, which is currently retrieved from a testee, with the reference waveform which was retrieved from the same testee when the testee was in a healthy condition. As such, the health care system can issue a driving signal when there is a large difference between the physiological waveform and the reference waveform.
In an embodiment, a health care system including a cloud database, a physiological sensor and a processor is disclosed. The cloud database is configured to store a reference waveform and an abnormal data record. The physiological sensor is configured to detect a detected part of a body and to generate a detected physiological signal. The processor is electrically connected to the cloud database and retrieves the reference waveform from the cloud database. The processor is electrically connected to the physiological sensor to receive the detected physiological signal, converts the detected physiological signal into a physiological waveform, compares the physiological waveform with the reference waveform to determine a frequency error and a peak error therebetween, generates a driving signal when the frequency error is not smaller than a frequency threshold and the peak error is not smaller than a peak threshold, and transmits the physiological signal to the cloud database as the abnormal data record. As such, the processor can compare the currently-retrieved physiological waveform with the reference waveform previously obtained, and issue the driving signal when there is a large difference between the physiological waveform and the reference waveform. The compared result can be sent to related personnel, increasing the efficiency of health management thereof.
In a form shown, the frequency threshold is substantially 10% of a frequency value of the reference waveform. As such, the processor can issue the driving signal when there is a certain difference between the physiological waveform and the reference waveform. The compared result can be sent to related personnel, increasing the efficiency of health management thereof.
In the form shown, the peak threshold is substantially 10% of a peak value of the reference waveform. As such, the processor can issue the driving signal when there is a certain difference between the physiological waveform and the reference waveform.

In the form shown, the physiological sensor is a resistor-type sensor. As such, the physiological sensor can generate the detected physiological signal through the detection of the resistance, attaining an efficient generation of the detected physiological signal.
In the form shown, the resistor-type sensor includes a resistor-type substrate and a metal nanowire array. The resistor-type substrate includes a sensing face. The metal nanowire array is disposed on the sensing face.

The plurality of light emitting sections is arranged on the emission area in intervals along a direction. As such, the light emitting unit can emit different kinds of lights with different wavelengths. When the light emitting unit emits lights towards the detected part of the body, although some part of the lights may not be able to penetrate certain tissue in the body due to its wavelength, another part of the lights is still able to reach the detected part. Thus, the detected physiological signal can be efficiently generated.
In the form shown, the health care system further includes a controller electrically connected to the light emitting unit. The controller is used to control the plurality of light emitting sections to sequentially emit the plurality of lights along the direction.

The cloud database 1 is used to store a reference waveform. The cloud database 1 may be a remote database that can be accessed through a wired or wireless network, such as Dropbox. The generation of the reference waveform is not limited. For example, the physiological sensor 2 can measure a detected part of the body of a healthy person to generate a reference physiological signal. The processor 3 converts the reference physiological signal into the reference waveform, and transmits the reference waveform to the cloud database 1 for storage. The reference waveform in the cloud database 1 may be used for subsequent data comparison. However, the cloud database 1 may store a plurality of reference waveforms. Each reference waveform represents the reference physiological signal of an individual person.
The physiological sensor 2 is used to detect the detected part of the body and to generate a detected physiological signal. The physiological sensor 2 may be a resistor-type sensor or a photoelectric sensor. The physiological sensor 2 may be a three-lead electrocardiogram signal sensor capable of detecting the physiological change between the normal and abnormal ECG signals. The physiological sensor 2 may also be combined with a wearable device so that it can be attached to the user. However, this is not used to limit the disclosure. In addition, the physiological sensor 2 may include a wireless transmission module 21, which can be a WIFI structure, a zigbee structure or a Bluetooth structure. As such, the physiological sensor 2 can be electrically connected to the processor 3 through the wireless transmission module 21, improving the convenience in data transmission.

The plurality of light emitting sections 231′ is arranged on the emission area 22a′ in even intervals along a direction D. The direction D may be parallel to an extending direction of the photoelectric substrate 22′. Each of the plurality of light emitting sections 231′ emits the light with a different wavelength. The quantity of the plurality of light emitting sections 231′ is not limited. In the embodiment, there are three light emitting sections 231′, including a red light emitting section 231a′, a green light emitting section 231b′ and a blue light emitting section 231c′. As such, the light emitting unit 23′ can emit different kinds of lights with different wavelengths. When the light emitting unit 23′ emits lights towards the detected part of the body, although some part of the lights may not be able to penetrate certain tissue in the body due to its wavelength, another part of the lights is still able to reach the detected part. Thus, the detected physiological signal can be efficiently generated.

The processor 3 may include a wireless transceiving module 31 electrically connected to the wireless transmission module 21 of the physiological sensor 2. The wireless transceiving module 31 may be a WIFI structure, a zigbee structure or a Bluetooth structure. As such, the processor 3 can be electrically connected to the physiological sensor 2 through the wireless transceiving module 31, improving the convenience in data transmission.
The reference waveform and the physiological waveform may be any physiology-related waveform. In the embodiment, each of the reference waveform and the physiological waveform may be an electrocardiogram (ECG) signal or an electromyogram (EMG) signal. Besides, the reference waveform and the physiological waveform may have the same sensing basis. In the embodiment, the sensing basis includes the testee and the part of the body on which the test is performed. When the reference waveform and the physiological waveform have the same sensing basis, it indicates that the reference waveform and the physiological waveform are measured from the same testee and the same body part. Therefore, the processor 3 can compare the physiological waveform, which is currently retrieved from the testee, with the reference waveform which was retrieved from the same testee when the testee was in a healthy condition. In this regard, the processor 3 can issue the driving signal when there is a large difference between the physiological waveform and the reference waveform. The compared result can be sent to related personnel, increasing the efficiency of health management thereof.
Specifically, the reference waveform was already stored in the cloud database 1, and the physiological sensor 2 can measure the detected part of the body of the testee to generate the reference physiological signal. Therefore, when the processor 3 receives and converts the detected physiological signal into the reference waveform, the processor 3 can retrieve the reference waveform of the detected part of the testee from the cloud database 1. The processor 3 compares the physiological signal with the reference waveform to determine the difference therebetween. Specifically, the processor 3 determines the frequency error and the peak error between the physiological signal and the reference waveform. When the frequency error is not smaller than the frequency threshold and the peak error is not smaller than the peak threshold, the processor 3 generates the driving signal to drive the related electronic device. Thus, the electronic device is able to send a warning message to the user. Since the processor 3 can compare the physiological waveform, which is currently retrieved from the testee, with the reference waveform which was retrieved from the same testee when the testee was in a healthy condition, the processor 3 can issue the driving signal when there is a large difference between the physiological waveform and the reference waveform. The compared result can be sent to related personnel (such as the testee or medical staff), increasing the efficiency of health management thereof.
In the above, the frequency threshold may be about 10% of the frequency value of the reference waveform, and the peak threshold may be about 10% of the peak value of the reference waveform. Under these values, the processor 3 can issue the driving signal when there is a certain difference between the physiological signal and the reference waveform. The compared result can be sent to related personnel (such as the testee or medical staff), increasing the efficiency of health management thereof.
Furthermore, when the frequency error is not smaller than the frequency threshold and the peak error is not smaller than the peak threshold, the processor 3 can also transmit the physiological signal to the cloud database 1 as an abnormal data record. In this arrangement, since the processor 3 can compare the currently-retrieved physiological waveform with the reference waveform previously obtained, the processor 3 can issue the driving signal when there is a large difference between the physiological waveform and the reference waveform. The physiological signal can be sent to the cloud database 1 as the abnormal data record for the reference of the related personnel (such as the testee or medical staff), increasing the efficiency of health management thereof.

Alternatively, based on the arrangement of the controller 4, the controller 4 is electrically connected to the light emitting unit 23′, and controls the plurality of light emitting sections 231′ to emit a different wavelength of light in a random manner. In the embodiment, the plurality of light emitting sections 231′ includes the red light emitting section 231a′, the green light emitting section 231b′ and the blue light emitting section 231c′. In this regard, the controller 4 can control the red light emitting section 231a′, the green light emitting section 231b′ and the blue light emitting section 231c′ to emit a red light, a green light or a blue light in a random manner. Based on this, when the plurality of light emitting sections 231′ emits different wavelengths of lights to the detected part of the body in a random manner, the light detector 24′ can receive the lights reflected from the detected part of the body. As such, the light detector 24′ can generate the detected physiological signal based on the reflected lights. For example, the light detector 24′ can generate the detected physiological signal based a certain wavelength of light, or based on the randomness of the reflected lights. As such, the detection accuracy can be improved.

In summary, the health care system according to the embodiment of the disclosure may use the processor 3 to compare the currently-retrieved physiological waveform with the reference waveform previously obtained. In this regard, the processor 3 can issue the driving signal when there is a large difference between the physiological waveform and the reference waveform.
