     The present disclosure relates to a blood pressure measuring module, and more particularly to a blood pressure measuring module applied to a wearable blood pressure measuring device. 
     BACKGROUND OF THE INVENTION 
     Currently, in all fields, the products used in many sectors such as pharmaceutical industries, computer techniques, printing industries or energy industries are developed toward elaboration and miniaturization. Among them, a blood pressure measuring module is regarded as a key technology. Therefore, how to create an innovative structure to break through the technical bottleneck is an important content of development. For example, in the pharmaceutical industries, many instruments or equipment, such as blood pressure measuring devices, which needs to be actuated by a driving force of fluid. Usually, a conventional motor and a gas valves are utilized to achieve the purpose of gas transportation. However, since the volumes of the conventional motor and the gas valve are limited, it is difficult to reduce the entire volume of such equipment. Namely, it is difficult to achieve the goal of minimization. Moreover, it is impossible to make it portable. On the other hand, when the conventional motor and the gas valve are actuated, noise is generated, and it results in inconvenience and uncomfortable use. 
     Therefore, a blood pressure measuring module applied to a wearable blood pressure measuring device is provided for the use of the industry, so as to overcome the above-mentioned drawbacks in the prior art and make the conventional instrument or equipment having a gas transportation device to meet the goals of small size, miniaturization and quietness, and having an ability of rapidly transporting high-flow gas.

That is, the converging plate mounting sections  11   c  with the required number are included on the converging plate  11 . In the embodiment, the converging plate  11  has a converging outlet  111  and the converging outlet  111  passes through the converging plate first surface  11   a  and the converging plate second surface  11   b .

In the embodiment, the converging plate protrusion  114  is disposed in and surrounded by the discharging groove  115 . The discharging outlet  116  is disposed at a center of the converging plate protrusion  114  and passes through the converging plate first surface  11   a  and the converging plate second surface  11   b . In such a manner, the converging second surface  11   b  of the converging plate  11  corresponds to and covers the chamber plate  12 , the gas outputted from the chamber plate  12  is converged in the guiding groove  112  of the converging plate  11 , and the gas converged in the guiding groove  112  is further transported to the converging outlet  111  for output.

In addition, there are a plurality of discharging outlets  116  corresponding to the plurality of converging plate mounting sections  11   c  for pressure relief and discharging the gas. 
     In the embodiment, each of the chamber plates  12  has a chamber plate first surface  12   a  and a chamber plate second surface  12   b . The chamber plate first surface  12   a  and the chamber plate second surface  12   b  are two surfaces opposite to each other. The converging plate  11  is disposed on the chamber plate first surface  12   a . A guiding chamber  121  is concavely formed on the chamber plate first surface  12   a , and a mounting frame slot  122  is concavely formed on the chamber plate second surface  12   b . In the embodiment, the guiding chamber  121  spatially corresponds to and is in communication with the converging groove  113  of the converging plate  11 . In other words, the guiding chamber  121  and the mounting frame slot  122  are respectively disposed on two opposite surfaces of the chamber plate  12 . In the embodiment, a converging chamber  123  is formed on a bottom of the mounting frame slot  122  and has at least one first communicating hole  124  disposed at the bottom.

Preferably but not exclusively, in the embodiment, there are three first communicating holes  124 . In the embodiment, a chamber plate protrusion  125  is formed in the converging chamber  121  and surrounded by the plurality of first communicating holes  124 . Each of the chamber plates  12  further has a second communicating hole  126  corresponding in position to a respective one of the discharging grooves  115  of the converging plate  11 , so that the second communicating hole  126  passes through the chamber plate first surface  12   a  and is in communication with the converging chamber  123 . 
     In the embodiment, the valve plates  13  are disposed between the converging plate  11  and the chamber plates  12 . When the valve plates  13  are carried and positioned on the chamber plate first surface  12   a  of the chamber plate  12 , each of the valve plates  13  abuts against a respective one of the chamber plate protrusions  125  of the plurality of chamber plates  12 .

The converging concave portion  132  abuts against a respective one of the chamber plate protrusions  125  of the plurality of chamber plates  12 , so that the valve hole  131  disposed in the converging concave portion  132  is closed by the respective one of the chamber plate protrusions  125 .

When the valve plate  13  is disposed between the converging plate  11  and the chamber plate  12 , the tenons  127  of the chamber plate  14  respectively extend through the positioning holes  134  of the valve plate  13  and into the mortises  117  of the converging plate  11  for fixing the valve plate  13 . 
     Please refer to  FIG. 9A ,  FIG. 9B  and  FIGS. 10A to 10E . In the embodiment, the gas transportation device  2  is disposed for outputting the gas, and mounted and positioned in the mounting frame slot  122  of the chamber plate  12  so as to close the converging chamber  123  and transport the gas into the converging chamber  123 . In the embodiment, the gas transportation device  2  includes a fluid inlet plate  21 , a resonance plate  22 , a piezoelectric actuator  23 , a first insulating plate  24 , a conducting plate  25  and a second insulating plate  26 . The fluid inlet plate  21 , the resonance plate  22 , the piezoelectric actuator  23 , the first insulating plate  24 , the conducting plate  25  and the second insulating plate  26  are sequentially stacked. The fluid inlet plate  21  has at least one fluid inlet hole  21   a , at least one convergence channel  21   b , and a convergence chamber  21   c . The at least one fluid inlet hole  21   a  is disposed for introducing the gas. The fluid inlet hole  21   a  correspondingly passes through the convergence channel  21   b , and the convergence channel  21   b  is converged to the convergence chamber  21   c . Thus, the gas introduced through the fluid inlet hole  21   a  is converged to the convergence chamber  21   c . In this embodiment, the number of the at least one fluid inlet hole  21   a  and the number of the at least one convergence channel  21   b  are the same, and the fluid inlet plate  21  has four fluid inlet holes  21   a  and four convergence channels  21   b , but not limited thereto. The four fluid inlet holes  21   a  correspondingly passes through the four convergence channels  21   b , and the four convergence channels  21   b  are converged to the convergence chamber  21   c.    
     In the embodiment, the resonance plate  22  is stickily disposed on the fluid inlet plate  21 , and has a central aperture  22   a , a movable part  22   b  and a fixed part  22   c . The central aperture  22   a  is disposed at the center of the resonance plate  22 , and is corresponding in position to the convergence chamber  21   c  of the fluid inlet plate  21 . The movable part  22   b  surrounds the central aperture  22   a  and corresponds in position to the convergence chamber  21   c . The fixed part  22   c  surrounds the movable part  22   b  and is fixedly attached on the fluid inlet plate  21 . 
     In the embodiment, the piezoelectric actuator  23  includes a suspension plate  23   a , an outer frame  23   b , at least one bracket  23   c , a piezoelectric element  23   d , at least one vacant space  23   e  and a bulge  23 E The suspension plate  23   a  is square-shaped because the square suspension plate  23   a  is more power-saving than the circular suspension plate. Generally, the consumed power of the capacitive load at the resonance frequency is positively related to the resonance frequency. Since the resonance frequency of the square suspension plate  23   a  is obviously lower than that of the circular square suspension plate, the consumed power of the square suspension plate  23   a  is fewer. Therefore, the square suspension plate  23   a  in this embodiment has the effectiveness of power-saving. The outer frame  23   b  surrounds an outer side of the suspension plate  23   a . At least one bracket  23   c  is connected between the suspension plate  23   a  and the outer frame  23   b  for providing an elastic support. The piezoelectric element  23   d  has a side, and a length of the side of the piezoelectric element  23   d  is less than or equal to that of the suspension plate  23   a . The piezoelectric element  23   d  is attached on a surface of the suspension plate  23   a , and when a voltage is applied to the piezoelectric element  23   d , the suspension plate  23   a  is driven to undergo a bending vibration. The at least one vacant space  23   e  is formed among the suspension plate  23   a , the outer frame  23   b  and the at least one bracket  23   c  and disposed for allowing the gas to pass through. The bulge  23   f  is disposed on the other surface of the suspension plate  23   a  that is opposite to the piezoelectric element  23   d . In the embodiment, the bulge  23   f  is a protruding structure that is formed as one piece on the other surface of the suspension plate  23   a  opposite to the piezoelectric element  23   d , and is formed by an etching process. 
     In the embodiment, the fluid inlet plate  21 , the resonance plate  22 , the piezoelectric actuator  23 , the first insulating plate  24 , the conducting plate  25  and the second insulating plate  26  are sequentially stacked. A chamber space  27  is formed between the suspension plate  23   a  and the resonance plate  22 , and the chamber space  27  can be formed by filling a gap between the resonance plate  22  and the outer frame  23   b  of the piezoelectric actuator  23  with a material, such as a conductive adhesive, but not limited thereto. Thus, a specific depth between the resonance plate  22  and the suspension plate  23   a  is maintained to allow the gas to pass rapidly. In addition, since the resonance plate  22  and the suspension plate  23   a  are maintained at a suitable distance, so that the contact interference therebetween is reduced and the generated noise is largely reduced. In some other embodiments, the thickness of the conductive adhesive filled into the gap between the resonance plate  22  and the outer frame  23   b  of the piezoelectric actuator  23  is reduced by increasing the height of the outer frame  23   b  of the piezoelectric actuator  23 . In that, the suspension plate  23   a  and the resonance plate  22  are maintained at a suitable distance and the thickness of conductive adhesive filled in each of the entire gas transportation device  2  is not influenced due to the hot pressing temperature and the cooling temperature. It avoids that the actual size of the chamber space  27  is influenced due to the thermal expansion and contraction after the entire gas transportation device  2  is assembled. In addition, the size of the chamber space  27  will affect the effectiveness of the gas transportation device  2 , therefore it is important to maintain the size of the chamber space  27 . Please refer to  FIG. 9A , in some other embodiments, the suspension plate  23   a  is formed by stamping to make it extend at a distance in a direction away from the resonance plates  22 . The extended distance can be adjusted through the at least one bracket  23   c  formed between the suspension plate  23   a  and the outer frame  23   b . Consequently, the top surface of the bulge  23   f  disposed on the suspension plate  23   a  and a coupling surface of the outer frame  23   b  are non-coplanar. That is, the top surface of the bulge  23   f  is away from the resonance plates  22 , and the top surface of the bulge  23   f  and the coupling surface of the outer frame  23   b  are non-coplanar. By utilizing a small amount of filling materials, such as a conductive adhesive applied to the coupling surface of the outer frame  23   b , the piezoelectric actuator  23  is attached to the fixed part  22   c  of the resonance plate  22  by hot pressing, thereby assembling the piezoelectric actuator  23  and the resonance plates  22  in combination. Thus, the structure of the chamber space  27  is improved by directly stamping the suspension plate  23   a  of the piezoelectric actuator  23  described above. In this way, the required chamber space  27  can be achieved by adjusting the stamping distance of the suspension plate  22  of the piezoelectric actuator  23 . It benefits to simplify the structural design of the chamber space  27 , and also achieves the advantages of simplifying the process and shortening the processing time. In addition, the first insulating plate  24 , the conducting plate  25  and the second insulating plate  26  are all thin frame-shaped sheets, but are not limited thereto, and are sequentially stacked on the piezoelectric actuator  23  to form the entire structure of micro pump of the gas transportation device  2 . 
     In order to understand the actuations of the gas transportation device  2 , please refer to  FIGS. 10C to 10E . Please refer to  FIG. 10C , when the piezoelectric element  23   d  of the piezoelectric actuator  23  is deformed in response to an applied voltage, the suspension plate  23   a  is driven to displace in the direction away from the resonance plate  22 . In that, the volume of the chamber space  27  is increased, a negative pressure is formed in the chamber space  27 , and the gas in the convergence chamber  21   c  is introduced into the chamber space  27 . At the same time, the resonance plate  22  is in resonance and is thus displaced synchronously. Thereby, the volume of the convergence chamber  21   c  is increased. Since the gas in the convergence chamber  21   c  is introduced into the chamber space  27 , the convergence chamber  21   c  is also in a negative pressure state, and the gas is sucked into the convergence chamber  21   c  through the fluid inlet holes  21   a  and the convergence channels  21   b . Then, as shown in  FIG. 10D , the piezoelectric element  23   d  drives the suspension plate  23   a  to displace toward the resonance plate  22  to compress the chamber space  27 . Similarly, the resonance plate  22  is actuated in resonance to the suspension plate  23   a  and is displaced. Thus, the gas in the chamber space  27  is further transported to pass through the vacant spaces  23   e  and it achieves the effectiveness of gas transportation. Finally, as shown in  FIG. 10E , when the suspension plate  23   a  is driven to return to an initial state, the resonance plate  22  is also driven to displace. In that, the resonance plate  22  pushes the gas in the chamber space  27  to the vacant spaces  23   e , and the volume of the convergence chamber  21   c  is increased. Thus, the gas can continuously pass through the fluid inlet holes  21   a  and the convergence channels  21   b , and can be converged in the convergence chamber  21   c . By repeating the actuations illustrated in  FIGS. 10C to 10E  continuously, the gas transportation device  2  can continuously transport the gas at high speed. The gas enters the fluid inlet hole  21   a , flows through a flow path formed by the fluid inlet plate  21  and the resonance plate  22  with a pressure gradient, and then is transported upwardly through the vacant spaces  23   e . It achieves the gas transporting operation of the gas transportation device  2 . 
     Please refer to  FIG. 10A , the fluid inlet plate  21 , the resonance plate  22 , the piezoelectric actuator  23 , the first insulating plate  24 , the conducting plate  25  and the second insulating plate  26  of each of the transportation devices  22  can be manufactured by a surface micromachining process of a micro-electromechanical-systems (MEMS). In such a manner, the volume of the gas transportation device  2  can be decreased to form a micro-electromechanical-systems pump. 
     In the embodiment, the plurality of gas transportation devices  2  are arranged in parallel and covered on one side of the module body  1 , and connected to the airbag  4  with the converging plate  11 , the plurality of chamber plates  12  and the plurality of valve plates  13  of the module body collaboratively to form the blood pressure measuring device  10 . As shown in  FIG. 8A , when the plurality of gas transportation devices  2  are actuated simultaneously, the gas is inhaled through the converging chamber  123  of each of the chamber plates  12  and flows through the first communicating hole  124  of each of the chamber plates  12 . In that, the gas is transported to push each of the valve plates  13  to move away from a corresponding one of the chamber plate protrusions  125 . In the embodiment, when the gas pushes the converging concave portion  132  of each of the valve plates  13  to move away from the corresponding one of the chamber plate protrusions  125 , the gas passes through the valve holes  131  of the valve plates  13  and is transported to the converging grooves  113  of the converging plate  11 . At the same time, the gas in the converging chambers  123  of the chamber plates  12  is transported through the second communicating holes  126  to contact the valve plates  13 , so that the discharging concave portions  133  of the valve plates  13  are pushed to abut against the converging plate protrusions  114  of the converging plate  11  respectively so as to close the discharging outlets  116 . Then, the gas is converged in the guiding groove  112  through the converging groove  113  and then flows into the converging outlet  111  of the converging plate  11  for discharging. Thus, the gas outputted from the module body  1  is introduced through the converging outlet  111  to the airbag  4 , and the airbag  4  is inflated rapidly for performing the blood pressure measurement. Moreover, the sensor  3  measures the gas pressure accumulated in the airbag  4 , and the blood pressure information of the user under monitoring is calculated. Please refer to  FIG. 8B . When the gas transportation devices  2  are not actuated, the gas in the converging outlet  111  of the converging plate  11  flows into the converging groove  113  through the guiding groove  112  and further flows into the discharging groove  115  through the guiding groove  112 . In that, the gas is transported to push the valve plate  13  which corresponds in position to the discharging groove  115  to move away from the corresponding one of the converging plate protrusions  114 . In the embodiment, when the gas is transported to push the discharging concave portion  133  of the valve plate  13  to move away from the corresponding one of the converging plate protrusions  114 , the discharging outlet  116  is opened. Then, the gas is discharged out of the converging plate  11  through the discharging outlet  116  for pressure relief.

The microprocessor  7  provides driving signals to the gas transportation device  2 , the sensor  3 , the optical sensor  6   a , the tri-axial accelerometer  6   b  and the communicator  8 , controls actuation of the gas transportation device  2 , receives measuring signals measured by the sensor  3  and the optical sensor  6   a , converts the measuring signals into information data, and transmits the information data through the communicator  8  to an external connection device  9  for storage, recording and carrying out a further analysis, so as to realize a physical health condition of the user much more. In the embodiment, the communicator  8  is configured as a wired transmission module or a wireless transmission module. Preferably but not exclusively, the wired transmission module is one selected from the group consisting of USB, mini-USB and micro-USB. Preferably but not exclusively, the wireless transmission module is one selected from the group consisting of a Wi-Fi module, a Bluetooth module, a radio frequency identification module and a near field communication module. In an embodiment, the communicator  8  further includes a wired transmission module and a wireless transmission module at the same time. The data transmission mode of the communicator  8  is adjustable according to the practical requirements. Any transmission mode for transmitting the physiological information of the user stored in the microprocessor  7  to the external connection device  9  can be implemented in the present disclosure. The present disclosure is not limited thereto, and not redundantly described herein. Preferably but not exclusively, the external connection device  9  is configured as at least one selected from the group consisting of a cloud system, a portable device and a computer system. In the embodiment, the external connection device  9  receives the information data transmitted from the blood pressure measuring module wore by the user, and carries out a further analysis and comparison of the information data through a self-learning artificial intelligence program in a statistical manner. Preferably but not exclusively, the self-learning artificial intelligence program is executed to analyze the information data of the user to generate an upper blood pressure and a lower blood pressure according to a medical standard. When the upper blood pressure and the lower blood pressure are out of range, a warning notice is fed back immediately to the blood pressure measuring device  10 , so as to realize the physical health condition of the user much more. 
     In the embodiment, the optical sensor  6   a  receives a reflected light from the user&#39;s skin tissue irradiated by an emitting light source and generates a detection signal, to achieve a photoplethysmography (PPG) measurement principle. The detection signal is provided to the microprocessor  7  and converted into health data information for output. The health data information includes one selected from the group consisting of heart rate data, electrocardiogram data and blood pressure data. The optical measurement is also a way to achieve blood pressure measurement. Although the optical measurement can be measured every minute and every second at any time, the health data information obtained from the optical measurement is generated through an algorithm adjustment, not directly measured by an inflatable measurement method. The result of the optical measurement is not accurate enough. In view of that, the present disclosure provides the blood pressure measuring module, which is miniaturized and suitable to be worn to achieve an inflatable blood pressure measuring method directly and obtain the most accurate information of blood pressure measurement value. In an embodiment, the accurate blood pressure measuring value is utilized as a calibration basis for an initial measurement of blood pressure of the optical sensor  6   a , and heart rate variability (HRV) and atrial fibrillation (AF) are utilized for auxiliary measurement confirmation compensation. That is, when the optical sensor  6   a  starts the first measurement, the inflatable blood pressure measurement method is implemented firstly in the blood pressure measuring module of the present disclosure, and the obtained health data information is used as the calculation basis for an initial measurement of blood pressure of the optical sensor  6   a . The compensation can be executed after each measuring result of the optical sensor  6   a , so as to achieve a more accurate measurement of health data information output. In addition, when a specific situation of the user occurs, it can be realized by the blood pressure measuring module. For example, in an embodiment, the tri-axial accelerometer  6   b  can be utilized for fall detection. A signal detected by the tri-axial accelerometer  6   b  is directly transmitted to the microprocessor  7  to control the driving of the gas transportation device  2  to inflate the airbag  4  for blood pressure measurement. The sensor  3  measures the gas pressure accumulated in the airbag  4 , and the blood pressure information of the user under monitoring is calculated, to realize the blood pressure information of the user. In another embodiment, when the user&#39;s abnormal blood pressure or abnormal blood oxygen is sensed by the optical sensor  6   a , the microprocessor  7  receives an abnormal condition according to a signal measured by the optical sensor  6   a , and directly controls the driving of the gas transportation device  2  to inflate the airbag  4  for blood pressure measuring. The sensor  3  measures the gas pressure accumulated in the airbag  4  or the pressure in contact with the user&#39;s skin, and the blood pressure information of the user under monitoring is calculated, to realize the blood pressure information of the user, so that the physical health condition of the user is realized when the specific situation of the user occurs, and warning notifications and treatment measures for first aid can be issued immediately. It is highly industrially utilized. 
     In the embodiment, when the blood pressure measuring module of the present disclosure is utilized to form the blood pressure measuring device  10  for performing blood pressure measurement, the microprocessor  7  controls the driving of the gas transportation device  2  every five minutes to sixty minutes to inflate the airbag  4  for automatically performing the blood pressure measurement once. Alternatively, the blood pressure measuring device  10  can be set by the user to perform the blood pressure measurement for storage, recording and carrying out the further analysis. In that, a continuous blood pressure monitoring result can be displayed in a convenient way for the user wearing the blood pressure measuring device  10 , so as to realize the physical health condition of the user much more. Moreover, the inflatable blood pressure measuring method is utilized directly in the blood pressure measuring module of the present disclosure, and an optical blood pressure measuring method measured by an optical sensor  6   a  is combined for calibration. The optical blood pressure measuring method is further combined with the self-learning artificial intelligence (AI) program through the external connection device  9 . The program can be responsible for 24-hour analysis and monitoring. If there is an abnormal situation, the blood pressure measuring device  10  including the blood pressure measurement module of the present disclosure is fed back to realize, and the gas transportation device  2  is activated to inflate the airbag  4  to perform a precise blood pressure measurement operation. Thus, the accurate blood pressure data information is obtained and provided to the user wearing the blood pressure measuring device  10  for realizing the health condition.
