     DETAILED DESCRIPTION OF THE INVENTION 
     For the sake of the advantages, spirits and features of the present invention can be understood more easily and clearly, the detailed descriptions and discussions will be made later by way of the embodiments and with reference of the diagrams. It is worth noting that these embodiments are merely representative embodiments of the present invention, wherein the specific methods, devices, conditions, materials and the like are not limited to the embodiments of the present invention or corresponding embodiments. Moreover, the devices in the figures are only used to express their corresponding positions and are not drawing according to their actual proportion. 
     In the description of the present invention, the description of the terms “one embodiment”, “another one embodiment” or “partial embodiment” or the like means that the specific features, structures, materials or characteristics described in connection with the embodiments are included in at least one implementation of the invention. In the present invention, the schematic representation of the above terms does not necessarily refer to the same embodiment. Furthermore, the particular features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments. 
     Please refer to  FIG. 1  and  FIG. 2 .  FIG. 1  is a simple schematic drawing illustrating an appearance of an intelligent pillbox with volume detection  1  of the present invention.  FIG. 2  is a functional block drawing illustrating the intelligent pillbox with volume detection  1  according to an embodiment of the present invention. In this embodiment, the intelligent pillbox with volume detection  1  includes an open-close structure  11 , a first structure  12 , an air pressure sensing module  14  and a processor  15 . The open-close structure  11  includes a containing space for containing a medicine, and the containing space is an airtight space when the open-close structure  11  is closed. The first structure  12  is movably configured on the open-close structure  11 , and the first structure  12  moves in and out of the airtight space to form a constant volume difference of the airtight space. The air pressure sensing module  14  is configured in the containing space for measuring a plurality of air pressure values in the airtight space. The air pressure values includes a first air pressure value and a second air pressure, wherein the first air pressure value is detected when the first structure  12  moves into the airtight space and the second air pressure value is detected when the first structure  12  moves out of the airtight space. An air pressure difference value is formed between the first air pressure value and the second air pressure value. The processor  15  is connected to the open-close structure  11 , and includes a volume calculating module  151  coupled to the air pressure sensing module  14 . The volume calculating module  151  calculates an air volume value of the airtight space according to the air pressure difference value and the constant volume difference, and calculates a medicine volume according to a maximum volume value of the containing space and the air volume value. In practical applications, when the patient takes the medicine out of the medicine box and then closes the medicine box, the intelligent pillbox with volume detection  1  can detect the total volume of the remaining medicine in the medicine box. Moreover, a first total volume of the medicine is calculated before opening the medicine box, and a second total volume of the medicine is calculated after closing the medicine box. The volume of taking medicine can be calculated by subtracting the first and the second total volume of the medicine, and then the medicine type and the number of the medicine by the medicine volume can also be judged. 
     Please refer to  FIG. 1 ,  FIG. 3 a    and  FIG. 3 b   .  FIG. 3 a    is a sectional schematic drawing illustrating the button moving out according to the embodiment of  FIG. 1 .  FIG. 3 b    is a sectional schematic drawing illustrating the button moving in according to the embodiment of  FIG. 1 . In one embodiment, the first structure  12  is a button set on and through the open-close structure  11 . The button includes a pressure applying end  121  and a pressure receiving end  122 . The pressure applying end  121  of the button is disposed in the containing space  110 , and the pressure receiving end  122  of the button is configured outside of the open-close structure  11 . The increased volume of the pressure applying end  121  in the containing space  110  is equal to the constant volume difference when an external force applies on the pressure receiving end  122  to make the button move into the airtight space. That is to say, the volume change of the containing space  110  is equal to the constant volume difference. In practical applications, when the patient closes the medicine box and presses the button into the open-close structure  11 , the air volume in the containing space  110  of the medicine box is changed because the volume of the button is increased in the containing space  110 , so as to change the air pressure in the medicine box. However, the medicine volume would not be changed by the increased volume of the button in the containing space  110 . Therefore, the medicine volume can be calculated by detecting the air pressure change and inversely calculating the air volume in the medicine box. Therefore, the intelligent pillbox with volume detection of the present invention can calculate the remaining medicine volume in the medicine box through volume difference value formed by the button moving into the open-close structure. 
     In another one embodiment, the decreased volume of the pressure applying end  121  in the containing space  110  is equal to the constant volume difference when the external force applies on the pressure receiving end  122  to make the button move out of the airtight space. This is another way to calculate the medicine volume by detecting the air pressure change and inversely calculating the air volume in the medicine box. 
     The intelligent pillbox with volume detection  1  calculates the pressure and volume changes of the box according to the Boyle&#39;s law to detect the number of remaining medicine. According to the ideal gas equation (PV=nRT) of the Boyle&#39;s law, the product of the pressure and volume of the gas is constant for the quantitative gas in the closed vessel and at constant temperature. That is to say, under the condition that the nRT of the ideal gas equation is constant, the pressure is inversely proportional to the volume. 
     In one embodiment, the air in the containing space  110  of the medicine box includes a first pressure P 1  and a first volume V 1  to be calculated when the button is not moved into the open-close structure  11 . The measureable first pressure P 1  is the environment atmosphere pressure (about 1 atm). The air pressure sensing module  14  of the medicine box can measure a second pressure P 2  of the air (about greater than 1 atm) after the button is moved into the open-close structure  11 . A second volume V 2  of the air is the first volume V 1  minus the volume value of the button moved into the containing space  110 . According to above conditions, the processor  15  of the medicine box can calculate the first volume V 1  by the ideal gas equation, and calculate the volume of remaining medicine of the medicine box by the maximum volume of the containing space  110  minus the first volume V 1  of the air. Therefore, the medicine box can calculate the number of remaining medicine of the medicine box by detecting the pressure in the containing space  110  of the medicine box and the fixed volume difference value. 
     In one embodiment, the containing space  110  of the medicine box includes a remaining air volume V 3  to be calculated, a measureable third pressure P 3  and a measureable pressure change ΔP when the button is moved into the open-close structure  11  with a volume change ΔV. The volume change ΔV is the constant volume difference mentioned above, and the third pressure P 3  and the pressure change ΔP are measured by the air pressure sensing module  14  of the medicine box. According to above conditions, the processor  15  of the medicine box can calculate the remaining air volume V 3  by the ideal gas equation, and calculate the volume of remaining medicine in the medicine box by the difference between the maximum volume of the containing space  110  and the remaining air volume V 3 . 
     In one embodiment, the relative precision of the barometer is 0.06 hPa. If the volume of the medicine box is 100 c.c., the most precise change value of the medicine volume that can be judged of the medicine box is 0.0059 c.c. Generally, the medicine for chronic diseases such as the 25 mg of Carvedilol used in hypertension has a single volume of 0.56 c.c., and the Nateglinide used for lowering blood glucose has a single volume of 0.3 c.c. The single volume of the medicines mentioned above and the volume difference between the different medicines are far greater than 0.0059 c.c. Therefore, the medicine box can precisely detect the remaining medicine volume of the medicine box through the minor pressure in the medicine box and the volume change, and can judge the medicine type according to the medicine volume. 
     Please continue refer to  FIG. 2 . In one embodiment, the intelligent pillbox with volume detection  1  further includes a storage module  16 . The storage module  16  is coupled to the volume calculating module  151  of the processor  15 . The storage module  16  further includes a personal medicine volume characteristic database  161 . The personal medicine volume characteristic database  161  stores a plurality of volume data of medicine. The processor  15  further includes a medicine type judging module  152 . The medicine type judging module  152  is coupled to the personal medicine volume characteristic database  161  and the volume calculating module  151 . 
     The volume calculating module  151  calculates the plurality of medicine volumes in multiple times and further calculates a volume change value respectively. The medicine type judging module  152  compares whether the volume data of the medicine matches the volume change value, and calculates a number of medicine taken out according to the volume change value and the volume data of the medicine. 
     In practical applications, the processor  15  can be a CPU, and the storage module  16  can be a memory card, a USB or a device with data storage function. The personal medicine volume characteristic database  161  can include the name, appearance description, volume and so on of the medicine, and can store the medicine data in the storage module  16  according to the medicine type that various patients need to take. Since the different types of medicines have different volumes, the volume and pressure in the medicine box are changed when the patient takes out the medicine and closes the medicine box. At this time, the volume calculating module  151  of the processor  15  can calculate the remaining medicine volume in the medicine box. Then, the volume calculating module  151  calculates the medicine volume taken out according to the remaining medicine volume of the medicine box after opening the medicine box and the remaining medicine volume in the medicine box calculated before opening the medicine box. Finally, the medicine type judging module  152  of the processor  15  compares and judges the type and the number of the medicine taken by the patient according to the medicine volume calculated by the volume calculating module  151  and the medicine data of the personal medicine volume characteristic database  161 . 
     Please refer to  FIG. 4 .  FIG. 4  is a functional block drawing illustrating the intelligent pillbox with volume detection  1  according to an embodiment of the present invention. In one embodiment, the intelligent pillbox with volume detection  1  further includes a time module  17  to record an instant time data. The storage module  16  further includes a medical order database  162 . The medical order database  162  includes a volume data and a corresponding time data for taking the medicine. The processor  15  further includes a medical order judging module  153  coupled to the time module  17  and the medical order database  162 . The medical order judging module  153  compares whether the volume change value before and after a period of the taking time data is equal to the volume data for taking the medicine according to the instant time data, if not, the medical order judging module  153  outputs a warning signal S 1 . 
     In practical applications, the time module  17  can be an electronic clock, and the electronic clock can display the instant time on the medicine box and record it. The medical order database  162  can include the volume data and the time data for taking the medicine, and can store the medicine data in the storage module  16  according to the medicine volume data and the time data for various patients to take medicine. For example, in the medical order data, the patient needs to take 0.5 c.c. of the medicine for lowering blood glucose after lunch, thus the intelligent pillbox can set the time for taking the medicine from 12:30 a.m. to 01:30 p.m. The intelligent pillbox will detect the volume of the medicine box at 01:30 p.m. If the volume change value is 0, the intelligent pillbox will output a warning signal S 1  to remind the patient for taking the medicine. In another one embodiment, the medical order database  162  not only can set the time for taking the medicine, but also can set multiple reminding times. When the time for taking the medicine is set from 12:30 a.m. to 01:30 p.m., the intelligent pillbox also can set the reminding times such as every 20 minutes in the time period. The intelligent pillbox will detect the volume of the medicine box at each reminding times. If the volume change value is 0, the intelligent pillbox will output a warning signal S 1  to remind the patient for taking the medicine. 
     In one embodiment, the medical order judging module  153  is further coupled to the medicine type judging module  152 . The medical order judging module  153  compares whether the number of medicine taken out matches a medicine data for taking the medicine, and compares whether the instant time data matches to the time data for taking the medicine. If either one does not match, the medical order judging module  153  outputs a warning signal S 1 . In practical applications, the patient sets the medicine box for taking 0.1 c.c. of the medicine for lowering blood pressure between 10:00 a.m. and 10:30 a.m. and 0.17 c.c. of the medicine for asthma between 09:00 p.m. and 10:00 p.m. according to the medical order. When the patient takes out the wrong medicine, for example, the patient takes out the medicine for asthma at 10:00 a.m., the medicine type judging module  152  of the processor  15  would detect that the volume change value of the medicine box is 0.17 c.c. Because the patient should take 0.1 c.c. of the medicine for lowering blood pressure in this time period, the medical order judging module  153  generates a warning signal S 1  and warns the patient for taking the wrong medicine according to the difference of the volume change value detected by the medicine type judging module  152  from the volume data for taking the medicine in the medical order. When the patient takes out the medicine during the non-medication period, for example, the patient takes out the medicine for asthma at 07:00 p.m., the medicine type judging module  152  of the processor  15  detects that the volume change value of the medicine box is 0.17 c.c. and then judges that the medicine is for asthma. Because it is not the time period for taking medicine for asthma, the medical order judging module  153  generates a warning signal S 1  and reminds the patient for the correct medication period according to the medicine data detected by the medicine type judging module  152  and the time data for taking the medicine in the medical order. 
     Please refer to  FIG. 5 .  FIG. 5  is a functional block drawing illustrating the intelligent pillbox with volume detection  1  according to an embodiment of the present invention. In one embodiment, the storage module  16  further includes a record database for taking the medicine  163  coupled to the time module  17  and the medicine type judging module  152 . The record database for taking the medicine  163  stores a record data for taking the medicine. The record data for taking the medicine includes the instant time data, the number of medicine taken out corresponding to the instant time data, the volume change value corresponding to the instant time data, and the air volume value corresponding to the instant time data. In practical applications, the record database for taking the medicine  163  stores the taking medicine time recorded by the time module  17 , and stores the volume change value, remaining volume value of the medicine box or the number of medicine type stored under the taking medicine time every time the patient takes the medicine. Therefore, the patient&#39;s medication history is stored in the record database for taking the medicine  163 , so that the patient&#39;s medication situation can be tracked in the future. 
     Please refer to  FIG. 6 .  FIG. 6  is a functional block drawing illustrating the intelligent pillbox with volume detection  1  according to an embodiment of the present invention. In one embodiment, the airtight space formed by closing the open-close structure has a maximum volume value. The processor  15  further includes a medicine inventory calculating module  154  coupled to the record database for taking the medicine  163 . The medicine inventory calculating module  154  stores a remaining time threshold value. The processor  15  calculates a remaining time of the air volume value reaching the maximum volume value according to the record data for taking the medicine, the medicine inventory calculating module  154  outputs a warning signal S 1  if the remaining time is less than the remaining time threshold value. 
     In practical applications, because chronic diseases require long-term medication, the doctor will usually make a continuous prescription, and the medicines received each time are usually one month&#39;s dose. The patient may forget to replenish the medicine into the medicine box resulting in forgeting to take the medicine if the patient needs to take many types of medicine. If the maximum volume value of the containing space of the medicine box is 40 c.c., the maximum volume value of the air of the containing space is also 40 c.c. If the total volume of the medicine is 20 c.c., that means the remaining air volume of the medicine box is 20 c.c. It is known from the record database for taking the medicine  163  that the total medicine value taken by the patient is 1 c.c., and the medicine will be exhausted after 20 days and the air volume in the containing space of the medicine box will reach a maximum. If the remaining time threshold value is set for 3 days, it means that the air volume of the containing space of the medicine box will reach the maximum volume value after 3 days of reaching the threshold value. Therefore, the medicine inventory calculating module  154  generates a warning signal S 1  to remind the patient to replenish the medicine into the medicine box when calculating the air volume in the containing space of medicine box reaching the maximum volume value in 3 days. 
     Please refer to  FIG. 7 .  FIG. 7  is a functional block drawing illustrating the intelligent pillbox with volume detection  1  according to an embodiment of the present invention. In one embodiment, the medicine inventory calculating module  154  is coupled to the volume calculating module  151  and the personal medicine volume characteristic database  161 . The airtight space formed by closing the open-close structure has a maximum volume value. The medicine inventory calculating module  154  calculates a number of remaining medicine types according to the maximum volume value and the air volume value. The medicine inventory calculating module  154  stores a quantity threshold value. The medicine inventory calculating module  154  outputs a warning signal S 1  when the number of remaining medicine types is less than the quantity threshold value. In practical applications, if the medicine box includes 10 pieces of medicines for lowering blood glucose, when the patient takes out the medicines, the medicine inventory calculating module  154  calculates the number of remaining medicines according to the volume difference value. If the quantity threshold value is 3, the medicine inventory calculating module  154  outputs a warning signal S 1  to remind the patient to replenish the medicine of the medicine box when calculating the number of remaining medicine for lowering blood glucose is less than 3. 
     Please refer to  FIG. 4 ,  FIG. 6  and  FIG. 7 . In one embodiment, the intelligent pillbox with volume detection  1  of the present further includes a sound-light output module  18  coupled to the processor  15 . The sound-light output module  18  outputs a reminder message when receiving the warning signal S 1  from the processor  15 . In practical applications, the sound-light output module  18  can be one selected from a buzzer, a warning light, a monitor with text display, or the combination thereof. The sound-light output module  18  generates the reminder message to remind the patient with notices such as whether forget taking medicine or not, take the wrong medicine or replenish the medicine of the medicine box when receiving the warning signal S 1  generated in above embodiments. 
     In one embodiment, the intelligent pillbox with volume detection  1  of the present further includes a wireless communicating module  19  coupled to the processor  15 . The wireless communicating module  19  is connected to a mobile device storing an application program for outputting the warning signal S 1  to the application program of the mobile device. In practical applications, the wireless communicating module  19  can be a Bluetooth module applied on an APP such as a medicine management APP. The mobile device can be a smart phone, and the medicine management APP is also installed in the smart phone. The warning signal S 1  is transmitted to the APP of the smart phone through the Bluetooth module when the medicine box outputs the warning signal S 1 . Therefore, the patient can understand the status of medication any time through the mobile device. In another one embodiment, the wireless communicating module  19  not only can transmit the warning signal S 1 , but also can transmit the data of the personal medicine volume characteristic database  161 , the medical order database  162  and the record database for taking the medicine  163  of the storage module  16 . Therefore, the patient can always understand the course of medication and the information of the medicine quantity. 
     In Summary, the intelligent pillbox with volume detection of the present invention calculates the medicine volume by generating the constant volume difference and detecting the air pressure change of the airtight space. It not only can prevent the patient from taking wrong medicine, but also can detect the number of remaining medicine and remind the patient to replenish the medicine in the medicine box.
