     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0017]    The embodiments of the apparatus and/or methods are disclosed. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It is apparent, however, to one skilled in the art that the present disclosure may be practiced without these specific details or with an equivalent arrangement. 
         [0018]    The embodiments of the present disclosure are able to apply in all kinds of drip bottle. 
         [0019]    Please refer to  FIG. 1  and  FIG. 2 .  FIG. 1  is a structure view of a warning device for an infusion apparatus which is installed at between a drip stand and a drip bottle.  FIG. 2  is a block diagram of a warning device for an infusion apparatus. In  FIG. 1 , a warning device for an infusion apparatus  1  is installed at between a drip stand  2  and a drip bottle  3 , in which the warning device  1  monitors a dosage value within the drip bottle  3 . 
         [0020]    In  FIG. 2 , the warning device  1  includes an alarm module  10 , a setting interface  12 , a measurement module  14 , a control module  16  and a power supply module  18 , in which the control module  16  electrically connects to the alarm module  10 , the setting interface  12 , the measurement module  14  and the power supply module  18  respectively. 
         [0021]    Then, the alarm module  10  includes a visual alarm unit  100  and an audible alarm unit  102 , in which the visual alarm unit  100  is a light emission element such as a LED or a lamp to make the light warning, and the audible alarm unit  102  is a sound device such as a buzzer to make the audible warning. In addition, the alarm module  10  has a primary warning mode and an emergency warning mode. When the alarm module  10  is in the primary warning mode, the alarm module  10  will executes the visual alarm unit  100  and the audible alarm unit  102  every minute in a time interval, so that the alarm module  10  has one time warning every minute in the time interval. When the alarm module  10  is in the emergency warning mode, the alarm module  10  will starts the visual alarm unit  100  and the audible alarm unit  102  sustained in the time interval, so that the alarm module  10  has warns continuously in the time interval to attain a more strongly warning for the user. 
         [0022]    The setting interface  12  is an operation platform for operating the warning device  1  which includes an adjustment modify unit  120  and a display unit  122 . The user can set a total dosage value by using the adjustment modify unit  120  according to the dosage how much the user want to inject, and the total dosage value can be showed on the display unit  122  for the user. The display unit  122  may be a display panel, and the adjustment modify unit  120  may has an increase key button and a decrease key button for adjusting the total dosage value. 
         [0023]    The measurement module may be an electronic scale, and further includes or connects to a hanging tool to hang the drip bottle  3  (as shown in the  FIG. 1 ). Generally, the electronic scale includes a weight sensor therein and the electronic scale will apply a voltage to the weight sensor. When an analytic object applying a weight on the weight sensor, weight sensor is deformed which is caused by the gravity so as to the resistance of the weight sensor is to be changed and the voltage is also to be change. When there is a change in the weight of the analytic object, the voltage is also to be changed. 
         [0024]    In other words, when the drip bottle  3  includes the drug therein on the hanging tool, the measurement module  14  will generate an origin voltage according to the weight of the drip bottle  3  which includes the drug therein. The measurement module  14  continuously monitors the voltage changed by changing the weight of the drip bottle  3  includes drug therein. With the dosage slowly drips into the patient&#39;s vein, the weight of the drip bottle  3  includes the dosage will be reduced. Thus, the measurement module  14  detects the voltage value which different from the original voltage value so as to a current voltage value is to be generated. It should be illustrated that in one infusion procedure, the initial voltage is defined as a constant value as the start of the infusion. Because there are many detection processes during the infusion process depended on the measuring frequency to generate a plurality of current voltage values. 
         [0025]    The control module  16  electrically connects to the alarm module  10 , the setting interface  12  and the measurement module  14  respectively. The control module  16  loads the total dosage value from the setting interface  12 , and receives the original voltage value and the current voltage value from the measurement module  14  and according to the total dosage value, the original voltage value and the current voltage value that measured in accordance with measurement rules to execute the control module  10  for warning alert actions 
         [0026]    Refer to  FIG. 3 , which is a flow chart of a measurement rule. According to the warning device for an infusion apparatus  1  of the present invention, the measurement rule includes the step S 50  denotes an original voltage that is received from a measurement module. The step S 51  denotes an original weight that is calculated corresponding to the original voltage, and the original weight is the original weight of the drip bottle with the dosage therein. The step S 52  denotes a ratio of the voltage and weight is calculated according to the original voltage and the original weight, and the ratio of the voltage and weight is a ratio value of the original voltage and the original weight. The step S 53  denotes a total dosage value that is loaded from the setting interface. The step S 54  denotes a current voltage is received from the measurement module and a voltage difference is calculated by comparing the current voltage and the original voltage. The step S 55  denotes a weight difference is calculated by the voltage difference and the ratio of the voltage and weight, in which the ratio of the voltage difference and the weight difference are equal to the ratio value of the original voltage and the original weight, and the weight difference is the decrease of the drip bottle  3  when the starting of the infusion of the drip bottle  3 , and the decrease of the drip bottle  3  is the amount of the infusion dosage. The step S 56  denotes a residual dosage is obtained from the total dosage value subtracted the weight difference and when the residual dosage is lower than a first warning value, the alarm module is executed to a primary warning mode in the step S 57 . When the residual dosage is lower than a second warning value, the alarm module is executed to an emergency warning mode in the step S 58 , and the first warning value is larger than the second warning value. 
         [0027]    For example, if the weight of 1 milliliter (ml) of the drug is 1 gram (g), the total weight of 200 ml dosage and drip bottle  3  with the dosage therein is 500 g and before the infusion treatment beginning, the measurement module  14  can detects an original voltage of the drip bottle  3  with the dosage therein which is denoted as the original voltage. The original voltage is transmitted to the control module  16  to calculate the original weight of the drip bottle  3  with the dosage therein is 500 g, which is the sum of the weight of the dosage and the drip bottle  3 . Then, the ratio of the voltage and weight of the drip bottle  3  with the dosage therein is to be calculated in step S 52 , if the dosage of the infusion is 200 ml, the user can set the total dosage value is 200 ml through the setting interface  12  and the control module  16  can load the total dosage value is 200 ml from the setting interface  12 . 
         [0028]    Then, in a measurement frequency, when the infusion dosage is dipped out off the drip bottle  3  is 10 ml, the measurement module  14  will measure the voltage according to the reduction of 10 ml of the drip bottle  3  containing the dosage therein, and the voltage is the current voltage. At this time, the control module  16  compares the current voltage value with the original voltage in accordance with the step S 54  to calculate the voltage difference and the weight difference is 10 g in accordance with the step S 55 . That is to say, the infusion of dosage is 10 ml. Thus, the residual dosage is 190 ml in the drip bottle  3  according to the step S 56 , and the residual dosage (190 ml) is larger than the first warning value such that the control module  16  did not execute the alarm module  10  to alarm. 
         [0029]    How ever, with more and more of the dosage is dripped out off the drip bottle  3 , the residual dosage within the drip bottle  3  is also fewer and fewer. When the residual dosage is lower than the first warning value, the control module  16  will executes the alarm module  10  to be the primary warning mode according to the step S 57  to alarm the dosage is to be exhausted and to be replaced or supplement for the user. If the dosage is still dripped out off the drip bottle  3  and the user does not replace a new drip bottle  3  or supplement more dosage into the drip bottle  3 , to let the residual dosage is lower than the second warning value such as 5 ml, the control module  16  transforms the alarm module  10  to an emergency warning mode from the primary warning mode to remind the dosage within the drip bottle  3  is to be run out for the user, whereby, by two-stages warning mechanism not only reduces the work loading and burden for the staff and improves the medical service quality of medical facilities can be improved by adding the alarm frequency. 
         [0030]    Furthermore, the user may add the additional drug into the drip bottle  3  during the infusion process. At this time, the user can adjust the dosage within the drip bottle  3  by the adjustment modify unit  120  of the setting interface  12  after additional drug is added into the drip bottle  3 . The added dosage is added to the total dosage value within the drip bottle  3 . For example, if the additional drug is 50 ml, the total dosage value within the drip bottle  3  is adjusted to 250 ml according to above measurement rule. That is to say, the original dosage is 200 ml that is to be changed as the 250 ml, in this way, the additional dosage of the drug will not affect the original timing for warning, to achieve higher compatibility and higher maneuverability. 
         [0031]    According to the above embodiments, the warning device  1  containing infusion apparatus further includes a power supply module  18 . The power supply module  18  is the power supply for the warning device  1 , and electrically connects to the control module  16 . The control module  16  compares the surplus power supply value and a power warning value, when the surplus power supply value is lower than the power warning value, the control module  16  will instruct the alarm module  10  to alarm a lower battery message. 
         [0032]    Certainly, the surplus power supply value can also display on the display unit  122  of the setting interface  12 . Thus, the surplus power supply value of the power supply module can show for the user clearly and convenience for charging. Otherwise, the above alarm message can also show on the display unit  122  of the setting interface  12 , and the residual dosage is calculated according to the step S 56  within the drip bottle  3  can also be displayed on the display unit  122  of the setting interface  12  to show the residual dosage more clearly for the user. 
         [0033]    Accordingly, the warning device can set the desired infusion dosage through the setting interface, the weight of the drip bottle is measured continuously by the measurement module, the residual dosage within the drip bottle is calculated according to the measurement rule of the control module and the control module executes the alarming when the residual dosage within the drip bottle is lower than the emergency warning value such that the work loading and burden for the staff and the quality of medical care of the medical facility can be improved. 
         [0034]    While the invention has been described in connection with a number of embodiments and implementations, the invention is not so limited but covers various obvious modifications and equivalent arrangements, which fall within the purview of the appended claims. Although features of the invention are expressed in certain combination among the claims, it is contemplated that these features can be arranged in any combination and order.
