The discharging outlet 116 is disposed at a center of the converging plate protrusion 114 and passes through the converging plate first surface 11a and the converging plate second surface 11b. In such a manner, the converging second surface 11b 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. Notably, when the plurality of converging plate mounting sections 11c with the required number are disposed on the converging plate 11, only one converging outlet 111 is correspondingly disposed on the converging plate 11, and the airbag 4 is collaboratively connected thereto for converging the gas. In addition, there are a plurality of discharging outlets 116 corresponding to the plurality of converging plate mounting sections 11c for pressure relief and discharging the gas.

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 21a, at least one convergence channel 21b, and a convergence chamber 21c. The at least one fluid inlet hole 21a is disposed for introducing the gas. The fluid inlet hole 21a correspondingly passes through the convergence channel 21b, and the convergence channel 21b is converged to the convergence chamber 21c. Thus, the gas introduced through the fluid inlet hole 21a is converged to the convergence chamber 21c. In this embodiment, the number of the at least one fluid inlet hole 21a and the number of the at least one convergence channel 21b are the same, and the fluid inlet plate 21 has four fluid inlet holes 21a and four convergence channels 21b, but not limited thereto. The four fluid inlet holes 21a correspondingly passes through the four convergence channels 21b, and the four convergence channels 21b are converged to the convergence chamber 21c.

In the embodiment, the resonance plate 22 is stickily disposed on the fluid inlet plate 21, and has a central aperture 22a, a movable part 22b and a fixed part 22c. The central aperture 22a is disposed at the center of the resonance plate 22, and is corresponding in position to the convergence chamber 21c of the fluid inlet plate 21. The movable part 22b surrounds the central aperture 22a and corresponds in position to the convergence chamber 21c. The fixed part 22c surrounds the movable part 22b and is fixedly attached on the fluid inlet plate 21.

In the embodiment, the piezoelectric actuator 23 includes a suspension plate 23a, an outer frame 23b, at least one bracket 23c, a piezoelectric element 23d, at least one vacant space 23e and a bulge 23E The suspension plate 23a is square-shaped because the square suspension plate 23a 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 23a is obviously lower than that of the circular square suspension plate, the consumed power of the square suspension plate 23a is fewer. Therefore, the square suspension plate 23a in this embodiment has the effectiveness of power-saving. The outer frame 23b surrounds an outer side of the suspension plate 23a. At least one bracket 23c is connected between the suspension plate 23a and the outer frame 23b for providing an elastic support. The piezoelectric element 23d has a side, and a length of the side of the piezoelectric element 23d is less than or equal to that of the suspension plate 23a. The piezoelectric element 23d is attached on a surface of the suspension plate 23a, and when a voltage is applied to the piezoelectric element 23d, the suspension plate 23a is driven to undergo a bending vibration. The at least one vacant space 23e is formed among the suspension plate 23a, the outer frame 23b and the at least one bracket 23c and disposed for allowing the gas to pass through. The bulge 23f is disposed on the other surface of the suspension plate 23a that is opposite to the piezoelectric element 23d. In the embodiment, the bulge 23f is a protruding structure that is formed as one piece on the other surface of the suspension plate 23a opposite to the piezoelectric element 23d, 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 23a 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 23b 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 23a is maintained to allow the gas to pass rapidly. In addition, since the resonance plate 22 and the suspension plate 23a 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 23b of the piezoelectric actuator 23 is reduced by increasing the height of the outer frame 23b of the piezoelectric actuator 23. In that, the suspension plate 23a 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 23a 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 23c formed between the suspension plate 23a and the outer frame 23b. Consequently, the top surface of the bulge 23f disposed on the suspension plate 23a and a coupling surface of the outer frame 23b are non-coplanar. That is, the top surface of the bulge 23f is away from the resonance plates 22, and the top surface of the bulge 23f and the coupling surface of the outer frame 23b 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 23b, the piezoelectric actuator 23 is attached to the fixed part 22c 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 23a 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 23d of the piezoelectric actuator 23 is deformed in response to an applied voltage, the suspension plate 23a 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 21c 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 21c is increased. Since the gas in the convergence chamber 21c is introduced into the chamber space 27, the convergence chamber 21c is also in a negative pressure state, and the gas is sucked into the convergence chamber 21c through the fluid inlet holes 21a and the convergence channels 21b. Then, as shown in FIG. 10D, the piezoelectric element 23d drives the suspension plate 23a 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 23a and is displaced. Thus, the gas in the chamber space 27 is further transported to pass through the vacant spaces 23e and it achieves the effectiveness of gas transportation. Finally, as shown in FIG. 10E, when the suspension plate 23a 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 23e, and the volume of the convergence chamber 21c is increased. Thus, the gas can continuously pass through the fluid inlet holes 21a and the convergence channels 21b, and can be converged in the convergence chamber 21c. 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 21a, 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 23e. 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.
