CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority from Taiwan Patent Application No. 103133376, filed on Sep. 25, 2014, in the Taiwan Intellectual Property Office, the content of which are hereby incorporated by reference in their entirety for all purposes. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    This application relates to a physiological nursing device, and a system and a method thereof, and more particularly, to a wearable device having active feedback characteristics for physiological nursing, a system and a method thereof. 
         [0004]    2. Description of the Related Art 
         [0005]    As the trend in the burgeoning technology of network and the miniaturized electronic components, the technique of the Internet of Things (IoT) along with the wearable technology can be applied to human body easier so as to monitor the vital signs in real-time. In addition, as the technology of cloud and network has been popularized, the wearable devices oriented to physiological nursing become more and more popular in human life. 
         [0006]    The conventional wearable devices, however, sense one&#39;s vital signs through the collected physiological sensing signals, and once the wearer is under certain special conditions such as the unusual raise of blood glucose, sleep apnea, sudden infant death syndrome (SIDS), and so on, the wearer is unable to ask for help as the unconsciousness. Although the conventional wearable devices are able to actively send e-mails, messages or a call for aid, it is well-known that one may likely be in coma in the abnormal physiological conditions such as in dyspnea about 3-5 minutes. If the period of dyspnea lasts out, the life may be gone. Moreover, if the unusual raise of blood glucose occurs to the wearer, syndrome such as retinopathy, arteriosclerosis, nephropathy, and so on may become inevitable. 
         [0007]    In conclusion, the lack of instant physiological nursing is indeed one of the drawbacks of the prior technology. No matter how accurate the sensed result is, the regret is unavoidable if an immediate physiological nursing cannot be provided adequately to the human body.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0027]    Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can realize the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. 
         [0028]    Please refer to  FIG. 1  which is a block diagram for showing a function of a wearable device having active feedback characteristics in accordance with one embodiment of the present invention. A wearable device  101  having a physiological signal sensing device  120  of the present invention is feasible to be worn on a wearer, and a control device  110  is connected with the physiological signal sensing device  120 . In addition, a feedback device  130  which is wearable is further provided. 
         [0029]    The feedback device  130  is connected with the control device  110 . The control device  110  is configured to determine whether a physiological sensing signal produced by the physiological signal sensing device  120  is within a safe range. When the control device  110  determines the physiological sensing signal produced by the physiological signal sensing device that is not within a safe range, the control device  110  is configured to actively command the feedback device  130  applying a preset functional response to the wearer. Wherein, the preset functional response enables the physiological sensing signal of the wearer returning to a stable state so as to be maintained within the safe range. 
         [0030]    What one skilled in the art can understand is that the control device  110 , the physiological signal sensing device  120  and the feedback device  130  may be integrated as a single device in the appearance, or the control device  110  and the physiological signal sensing device  120  may be integrated as a single device (shown in  FIG. 3 ) or the other forms of arrangement. As only one control end, which is mainly configured to control the signals, is necessary to the physiological signal sensing device  120  and the feedback device  130 , devices having the related functions do not depart from the scope of the present invention. 
         [0031]    The feedback device  130  and the physiological signal sensing device  120  disclosed in the present invention may be able to cooperate with each other, that is to say, when the physiological signal sensing device  120  senses that the physiological condition of the wearer is in danger, the feedback device  130  is configured to apply adequate treatment to the wearer to enable the physiological sensing signal of the wearer returning to a stable state so as to be maintained within the safe range. For example, when the physiological signal sensing device  120  is configured to sense the wearer&#39;s blood oxygen saturation (e.g. using infrared to irradiate the wearer&#39;s skin, and extracting the reflected light to analyze, or the other sensing devices feasible to obtain the blood oxygen saturation), the setting of the control device  110  relative to the safe range means the normal numeral of blood oxygen saturation. If the numeral of the physiological sensing signal sensed by the physiological signal sensing device  120  is not within the safe range (the numeral is usually set to higher than a threshold value), the control device  110  actively commands the feedback device  130  to release current (e.g. current releaser configured to release a low frequency current through an anode patch and a cathode patch adhered to the wearer) to awaken the wearer&#39;s consciousness through the current. As the reduction of blood oxygen saturation is usually caused by dyspnea or insufficient respiratory capacity, the wearer may fall into a shock within 3-5 minutes and the brain organization may hence be damaged if an immediate treatment cannot be done. As a result, the present invention is to apply a physiological nursing system cooperating with the feedback device  130  having active feedback characteristics to provide an adequate treatment instantly according to different physiological conditions so as to seize the precious time for treatment. 
         [0032]    The feedback device  130  mentioned in the present invention may include at least one of a sound player, a vibrator, a current releaser, and a medicine releaser. Wherein a preset functional response the sound player is to play a preset sound, a preset functional response of the vibrator is to produce a vibration, a preset functional response of the current releaser is to produce an effect of electric shock caused by an anode patch and a cathode patch, and a preset functional response of the medicine releaser is to apply a medicine to the wearer. Wherein, the medicine releaser may sense the physiological signal relative to the wearer&#39;s blood glucose, and when the amount of blood glucose is abnormal, an adequate treatment can be done immediately. For example, the control device  100  may command a medicinal patch to release an adequate amount of insulin which can be absorbed by the wearer&#39;s skin so as provide the instant aid. Besides the aforementioned method, injection or the other methods which can be absorbed by human body may be applied to the feedback device  130  as well. 
         [0033]    Please refer to  FIG. 2  which is a block diagram for showing a function of a wearable device having active feedback characteristics in accordance with another embodiment of the present invention. The embodiment further includes a wireless communication module  140  which is connected with the control device  110  compared with the embodiment of  FIG. 1 . The wireless communication module  140  is connected with a first electronic communication device  200  such that the physiological signal can be transmitted to the first electronic communication device  200 . Wherein, the wireless communication module  140  may be a near field communication module such as NFC, or a far field communication module such as Bluetooth and Wi-Fi connected with the first electronic communication device  200  via wireless connection. On the other hand, the first electronic communication device  200  may be directly connected with the wearable device  101  (not shown) through an universal serial bus (USB) to receive the physiological sensing signal; and additionally, the physiological sensing signal may be transmitted to a second electronic communication device  300  located in a remote end as well. Furthermore, firmware or operational software of the wearable device  101  may be updated through the first electronic communication device  200 . 
         [0034]    Please refer to  FIG. 3  which is a three-dimensional schematic diagram for showing a function of a wearable device having active feedback characteristics in accordance with another embodiment of the present invention. The wearable device  101  may be fixed on the wearer&#39;s wrist by tape or Velcro fasteners, and then the physiological signal sensing device  120  may be adjusted in a right sensing part to sense the physiological signal of the wearer.  FIG. 3  shows a wearable device having two feedback devices  131 ,  132 . The first feedback device  131  uses a type as an example, and the first feedback device  131  is controlled by the control device  110  to apply the above-mentioned insulin at an appropriate time. The second feedback device  132  takes the two electrode patches used to release a low frequency current as an example; likewise, the second feedback device  132  is controlled by the control device  110  to release current to produce an effect of electric shock at an appropriate time. 
         [0035]    Please refer to  FIG. 4  which is a flow chart of a physiological nursing method having active feedback characteristics in accordance with one embodiment of the present invention. As shown in the figure, the operational steps are sated as follow. 
         [0036]    In step S 100 , a physiological condition of a wearer is sensed to produce a physiological sensing signal. 
         [0037]    In step S 200 , whether the physiological sensing signal is determined within a safe range. If the result is “positive”, step S 300  is entered, and if the result is “negative”, the procedure backs to step S 100 . 
         [0038]    In step S 300 , a preset functional response relative to the wearer is actively applied to the wearer through the feedback device when the sensed physiological sensing signal is not within the safe range. After the application is made (an adequate amount is usually added in advance), the procedure backs to step S 100 . 
         [0039]    Wherein, the preset functional response enables the physiological sensing signal of the wearer returning to a stable state. If an initial application is insufficient, the wearable device keeps performing the physiological nursing, namely, a second application is made. The number of the nursing may be set in advance to enable the control device  110  executing the nursing procedures according to the practical situation or different physiological conditions. 
         [0040]    Please refer to  FIG. 5  which is a flow chart of a physiological nursing method having active feedback characteristics in accordance with another embodiment of the present invention. The difference between  FIG. 5  and  FIG. 4  lies in that whether the physiological sensing signal is determined within a safe range is made in step S 200 . If the result is “positive”, step S  300  is entered, and if the result is “negative”, the procedure enters step S 401 . In step S 401 , a physiological signal is transmitted to a remote end monitoring host, wherein the remote end monitoring host is a monitoring host (i.e. the aforementioned second electronic communication device  300 ), and the monitoring host is stored with preset physiological data. Afterwards, step S 403  is entered. The monitoring host determines whether the preset functional response has to be applied to the wearer corresponding to the preset physiological data and the physiological sensing signal when the physiological sensing signal is within the safe range. If the result is “positive”, the step S 300  is entered, and if the result is “negative”, it goes to step S 100 . The extra step is determined by an added remote end monitoring host. For example, as the monitoring host is stored with a huge amount of data concerning identical physiological conditions, a more careful judgment mechanism is therefore provided. That to say, the monitoring host is stored with the historical data of the wearer, and the preset functional response relative to the wearer is hence forced to be actively applied through the feedback device in a certain particular cycle. 
         [0041]    Please refer to  FIG. 6  which is a flow chart of a physiological nursing method having active feedback characteristics in accordance with another embodiment of the present invention. The difference between  FIG. 6  and  FIG. 4  lies in that whether the physiological sensing signal is determined within a safe range is made in step S 200 . If the result is “positive”, it goes to step S 300  and S 500 , and if the result is “negative”, it enters step S  100 . Wherein, the physiological sensing signal is transmitted to the remote end in step S 500 . For example, the above-mentioned first electronic device is disposed with a global positioning system and a mobile communication module, and when the physiological sensing signal is not within the safe range, the first electronic communication device transmits the physiological sensing signal and position data produced by the global positioning system to the second electronic communication device (i.e. the remote end) through the mobile communication module. Wherein, the remote end is at least one of an electric communication device of a preset contactor and a nearby medical institute provided by the position data. As a result, when the physiological sensing signal is abnormal, a wearable device having active feedback characteristics for physiological nursing and a method having active feedback characteristics for physiological nursing in accordance with the present invention not only provide an adequate treatment in no time, but also inform the family or the nearby medicinal institute to obtain the follow-up aid. 
         [0042]    While the means of specific embodiments in present invention has been described by reference drawings, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims. The modifications and variations should in a range limited by the specification of the present invention.
