Description
Technical Field
[0001] The present invention relates to a blood pressure measurement module, and more particularly to a blood pressure measurement module that can be applied to a wearable blood pressure measurement device. Background Art
[0002] At present, in various fields, whether it is medicine, computer technology, printing, energy and other industries, products are developing in the direction of refinement and miniaturization, among which the blood pressure measurement module is its key technology. Therefore, how to break through its technical bottleneck through innovative structure is an important content of development. For example, in the pharmaceutical industry, many instruments or equipment that need to be driven by gas power, such as blood pressure monitors, usually use traditional motors and gas valves to achieve the purpose of gas delivery. However, due to the volume limitations of these traditional motors and gas valves, it is difficult for such instruments and equipment to reduce the volume of the overall device, that is, it is difficult to achieve the goal of thinness, and it is even more impossible to achieve the purpose of portability. In addition, traditional motors and gas valves will also produce noise problems during operation, resulting in inconvenience and discomfort in use.
[0003] Therefore, it is necessary to develop a method to improve the above-mentioned deficiencies of the known technology, so that the traditional instruments or equipment using fluid transmission devices can achieve the goals of small size, miniaturization and silence, and have the ability to quickly transmit high-flow gas. Therefore, this case provides a blood pressure measurement module, which is applied to a wearable blood pressure measurement device for industrial use. Summary of the invention
[0004] The main purpose of this case is to provide a blood pressure measurement module that can be easily implemented in a blood pressure measurement device, and obtain the most accurate blood pressure measurement value information by directly measuring blood pressure with an inflation method and calibrating it with an optical blood pressure measurement method detected by an optical sensor. It can also be connected to a self-learning artificial intelligence (AI) program through an external connection device, responsible for 24-hour analysis and monitoring, and has the benefits of abnormal feedback and notification warnings.
[0005] A broad implementation of the present case is a blood pressure measurement module, which includes at least one module body connected to an airbag to control the inflation and exhaust operations of the airbag; at least one gas transmission device to control the gas flow; at least one sensor to monitor the changes in the gas pressure in the airbag or the pressure in contact with the user's skin; wherein the gas transmission device forms gas transmission when driven, allowing the gas to be introduced into the module body and gathered in the airbag, causing the airbag to expand for blood pressure measurement operations, and the sensor monitors the pressure of the gas gathered in the airbag or the pressure in contact with the user's skin, and calculates the blood pressure information of the monitored user.

When the gas transmission device 2 is driven, gas transmission is formed, so that the gas is introduced into the module body 1 and gathered to the airbag 4 to expand (such as Figure 6B As shown in FIG. 1 ), the sensor 3 can be pressed against the user's skin A to compress the artery C between the user's bone B and skin A. The sensor 3 is pressed against the user's artery C and uses applanation scanning to monitor the target artery C and calculate the blood pressure information of the monitored user (as shown in FIG. 1 ).

[0103] Of course, in the embodiment of the present case, in order to ensure that the valve plate 13 is firmly positioned between the cavity plate 12 and the manifold plate 11 without displacement, the cavity plate 12 is provided with a plurality of tenons 127 on the first surface 12a of the cavity plate, and the valve plate 13 is supported on the first surface 12a of the cavity plate 12, and a positioning hole 134 is provided corresponding to the tenon 127, and the manifold plate 11 is supported on the valve plate 13, and a tenon hole 117 is provided corresponding to the position of the positioning hole 134 of the valve plate 13, so that when the valve plate 13 is set between the manifold plate 11 and the cavity plate 12, the tenon 127 of the cavity plate 12 can be used to extend into the positioning hole 134 of the valve plate 13, and then embedded in the tenon hole 117 of the manifold plate 11, so that the valve plate 13 is positioned without displacement.
[0104] See also Fig. 9A , Fig. 9B , FIG. 10A to FIG. 10E As shown, the above-mentioned gas transmission device 2 controls the flow of gas and is arranged and positioned in the supporting frame groove 122 of the cavity plate 12 to close the collecting chamber 123 and operate to transport gas to the collecting chamber 123. The gas transmission device 2 is composed of an inlet plate 21, a resonance plate 22, a piezoelectric actuator 23, a first insulating plate 24, a conductive plate 25 and a second insulating plate 26 stacked in sequence, wherein the inlet plate 21 has at least one inlet hole 21a, at least one bus groove 21b and a bus chamber 21c, the inlet hole 21a is used to introduce gas, the inlet hole 21a corresponds to the through bus groove 21b, and the bus groove 21b converges to the convergence chamber 21c, so that the gas introduced by the inlet hole 21a can be converged into the convergence chamber 21c. In this embodiment, the number of inlet holes 21a and bus bar slots 21b is the same, and the number of inlet holes 21a and bus bar slots 21b are 4 respectively, but not limited thereto. The 4 inlet holes 21a respectively penetrate the 4 bus bar slots 21b, and the 4 bus bar slots 21b converge into the confluence chamber 21c.
[0105] The above-mentioned resonance plate 22 can be assembled on the inlet plate 21 by bonding, and the resonance plate 22 has a hollow hole 22a, a movable part 22b and a fixed part 22c. The hollow hole 22a is located at the center of the resonance plate 22 and corresponds to the confluence chamber 21c of the inlet plate 21. The movable part 22b is arranged around the hollow hole 22a and in the area opposite to the confluence chamber 21c, and the fixed part 22c is arranged on the outer peripheral edge of the resonance plate 22 and is fixed to the inlet plate 21.
[0106] 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 gap 23e and a protrusion 23f. The suspension board 23a is a square suspension board. The suspension board 23a is square because compared with the circular suspension board, the square suspension board 23a has the advantage of saving power. The power consumption of the capacitive load operating at the resonance frequency increases with the increase of the frequency. Since the resonance frequency of the square suspension board 23a is obviously lower than that of the circular suspension board, the relative power consumption is also obviously lower. That is, the square suspension board 23a adopted in this case has the advantage of saving power. The outer frame 23b is arranged around the outer side of the suspension board 23a. At least one bracket 23c is connected between the suspension board 23a and the outer frame 23b to provide a supporting force for elastically supporting the suspension board 23a. The piezoelectric element 23d has a side length that is less than or equal to the side length of the suspension board 23a, and the piezoelectric element 23d is attached to a surface of the suspension board 23a to receive a voltage to drive the suspension board 23a to flexurally vibrate. The suspension board 23a and the outer frame 23b At least one gap 23e is formed between the bracket 23c for gas to pass through; the protrusion 23f is arranged on the other surface opposite to the surface of the suspension plate 23a attached to the piezoelectric element 23d. In this embodiment, the protrusion 23f can also be a convex structure formed by using an etching process on the suspension plate 23a to be integrally formed and protruding from the other surface opposite to the surface of the suspension plate 23a attached to the piezoelectric element 23d.
[0107] The inlet plate 21, the resonance sheet 22, the piezoelectric actuator 23, the first insulating sheet 24, the conductive sheet 25 and the second insulating sheet 26 are stacked and assembled in sequence, wherein a chamber space 27 is required to be formed between the suspension plate 23a and the resonance sheet 22. The chamber space 27 can be formed by filling a material, such as conductive glue, in the gap between the resonance sheet 22 and the outer frame 23b of the piezoelectric actuator 23, but not limited thereto, so that a certain depth can be maintained between the resonance sheet 22 and the suspension plate 23a to form the chamber space 27, thereby guiding the gas to flow more rapidly, and because the suspension plate 23a and the resonance sheet 22 maintain an appropriate distance, the contact interference between each other is reduced, so that the noise can be reduced. Of course, in some embodiments, the thickness of the conductive glue filled in the gap between the resonance sheet 22 and the outer frame 23b of the piezoelectric actuator 23 can be reduced by increasing the height of the outer frame 23b of the piezoelectric actuator 23, so that the chamber space 27 is formed. In this way, the gas transmission device 2 The overall structure assembly is not indirectly affected by the hot pressing temperature and cooling temperature of the conductive adhesive filling material, which can prevent the conductive adhesive filling material from affecting the actual spacing of the chamber space 27 after molding due to thermal expansion and contraction factors, but it is not limited to this; in addition, the chamber space 27 will affect the transmission effect of the gas transmission device 2, so maintaining a fixed chamber space 27 is very important for the gas transmission device 2 to provide a stable transmission efficiency. Fig. 9A As shown, in some other embodiments, the suspension plate 23a can be formed by stamping to extend outward for a certain distance, and the distance of the extension can be adjusted by forming at least one bracket 23c between the suspension plate 23a and the outer frame 23b, so that the surface of the protrusion 23f on the suspension plate 23a and the surface on the same side of the outer frame 23b form a non-coplanar surface, that is, the surface of the protrusion 23f will be away from the resonance plate 22 and will not be on the same plane as the surface of the outer frame 23b, and a small amount of filling material is applied on the assembly surface of the outer frame 23b (that is, the surface on the same side as the protrusion 23f) , for example, conductive glue, by hot pressing to make the piezoelectric actuator 23 adhere to the fixed part 22c of the resonance plate 22, so that the piezoelectric actuator 23 can be assembled with the resonance plate 22, so that the suspension plate 23a of the piezoelectric actuator 23 is directly stamped to form a chamber space 27. The required chamber space 27 can be completed by adjusting the stamping distance of the suspension plate 23a of the piezoelectric actuator 23, which effectively simplifies the structural design of adjusting the chamber space 27, and also achieves the advantages of simplifying the process and shortening the process time. In addition, the first insulating sheet 24, the conductive sheet 25 and the second insulating sheet 26 are all frame-shaped thin sheets, which are stacked on the piezoelectric actuator 23 in sequence to form the overall structure of a micro pump gas transmission device 2.
[0108] To understand the output operation mode of the gas transmission device 2 for gas transmission, please continue to refer to FIG. 10C to FIG. 10E Please refer to Fig. 10C, the piezoelectric element 23d of the piezoelectric actuator 23 is deformed after the driving voltage is applied, driving the suspension plate 23a to move in the direction away from the resonance plate 22. At this time, the volume of the chamber space 27 is increased, and a negative pressure is formed in the chamber space 27, so that the gas in the confluence chamber 21c is drawn into the chamber space 27. At the same time, the resonance plate 22 is synchronously displaced under the influence of the resonance principle, thereby increasing the volume of the confluence chamber 21c. Because the gas in the confluence chamber 21c enters the chamber space 27, the confluence chamber 21c is also in a negative pressure state, and then the gas is drawn into the confluence chamber 21c through the inlet hole 21a and the bus groove 21b; please refer to Fig. 10D The piezoelectric element 23d drives the suspension plate 23a to move toward the direction close to the resonance plate 22, compressing the chamber space 27. Similarly, the resonance plate 22 moves due to resonance with the suspension plate 23a, forcing the gas in the chamber space 27 to be synchronously pushed and transmitted through the gap 23e to achieve the effect of transmitting gas. Finally, please refer to Fig.10E When the suspension plate 23a is driven to return to the state where it is not driven by the piezoelectric element 23d, and the resonance plate 22 is also driven to move away from the inlet plate 21, the resonance plate 22 will compress the gas in the chamber space 27 to move it to the gap 23e, and increase the volume in the confluence chamber 21c, so that the gas can continue to pass through the inlet hole 21a and the bus groove 21b to converge in the confluence chamber 21c. By repeating the above process continuously, FIG. 10C to FIG. 10E The gas transmission device 2 shown provides a gas transmission actuation step, so that the gas transmission device 2 can continuously enter the flow channel formed by the flow inlet plate 21 and the resonance plate 22 from the flow inlet hole 21a to generate a pressure gradient, and then transmit the gas upward through the gap 23e to make the gas flow at a high speed, thereby achieving the actuation operation of the gas transmission device 2 to transmit the gas output.
[0109] Please continue reading Fig. 10A The inlet plate 21, the resonance plate 22, the piezoelectric actuator 23, the first insulating plate 24, the conductive plate 25 and the second insulating plate 26 of the gas transmission device 2 can all be manufactured through the micro-electromechanical surface micro-machining technology process, so that the volume of the gas transmission device 2 can be reduced, and the gas transmission device 2 can constitute a micro pump of a micro-electromechanical system.
[0110] The blood pressure measurement module of this case has multiple gas transmission devices 2 connected in parallel and sealed on one side of the module body 1, and the module body 1 uses a manifold 11, multiple cavity plates 12, and multiple valve plates 13 to connect the airbag 4 to form a blood pressure measurement device 10. Fig. 8AAs shown, when multiple gas transmission devices 2 are operated simultaneously, the gas is supplied to the manifold chamber 123 of the cavity plate 12, passes through the connecting hole 124 of the cavity plate 12, and pushes the valve plate 13 out of the state of abutting against the cavity plate convex portion 125. In this embodiment, the gas pushes the concave concave plate 132 of the valve plate 13 away, so that the concave concave plate 132 is out of the state of abutting against the cavity plate convex portion 125, and the supplied gas passes through the valve hole 131 of the valve plate 13 and flows to the confluence of the confluence plate 11. The gas in the collecting chamber 123 of the cavity plate 12 can also contact the valve plate 13 through the second connecting hole 126 to push the discharge concave plate 133 of the valve plate 13 to contact the convex part 114 of the collecting plate and close the discharge outlet 116. The gas is then connected to the guide groove 112 by the collecting groove 113, and then flows into the collecting outlet 111 of the collecting plate 11 for collecting and outputting. Therefore, the gas output by the module body 1 will be connected to the airbag 4 by the collecting outlet 111 and expand it quickly to form a blood pressure measurement operation, and the pressure of the gas gathered in the airbag 4 is monitored by the sensor 3 to calculate the blood pressure information of the monitored user. Please refer to Figure 8B As shown, when all the gas transmission devices 2 are not in operation, the gas can flow into the confluence groove 113 through the confluence outlet 111 and the guide groove 112 of the confluence plate 11, and then flow into the discharge groove 115 through the guide groove 112 to push the valve plate 13 out of the state of abutting against the confluence plate protrusion 114. In this embodiment, the gas pushes the discharge concave plate 133 of the valve plate 13 out of the state of abutting against the confluence plate protrusion 114, opens the discharge outlet 116, and then is discharged outside the confluence plate 11 through the discharge outlet 116 to perform a pressure relief operation.
[0111] See also Figure 1 and Fig.11As shown, the blood pressure measurement module of the present case further includes a driving circuit board 5, an optical sensor 6a, a three-axis acceleration sensor 6b, a microprocessor 7 and a communicator 8. Among them, the gas transmission device 2, the sensor 3, the optical sensor 6a, the three-axis acceleration sensor 6b, the microprocessor 7 and the communicator 8 are all packaged and arranged on the driving circuit board 5 for electrical connection, and the microprocessor 7 provides driving signals for the gas transmission device 2, the sensor 3, the optical sensor 6a, the three-axis acceleration sensor 6b and the communicator 8, and controls the driving operation of the gas transmission device 2, and receives the measured signals from the sensor 3 and the optical sensor 6a to calculate and convert them into information data, and transmits the information data to an external connection device 9 through the communicator 8 for storage and recording for further analysis and statistics, so as to better understand the physiological health status of the wearer. The communicator 8 may be wired transmission, such as USB transmission, mini-USB transmission or micro-USB transmission, but not limited thereto; in other embodiments, the communicator 8 may also be wireless transmission, such as Wi-Fi transmission, Bluetooth transmission, radio frequency identification transmission (Radio Frequency Identification, RFID) or near field communication transmission (Near Field Communication, NFC), but not limited thereto; and the communicator 8 may also include both wired transmission and wireless transmission, and its data transmission mode may be changed according to the actual implementation situation. Any implementation that can transmit the physiological information of the wearer stored in the microprocessor 7 to the external connection device 9 is within the protection scope of this case and will not be described in detail. In this embodiment, the external connection device 9 can be but not limited to a cloud system, a portable device, a computer system, etc. The multiple external connection devices 9 mainly receive the physiological information of the wearer transmitted by the blood pressure measurement module of this case, and can further analyze and compare the multiple information through a statistical self-learning artificial intelligence (AI) program to form an upper and lower blood pressure range that meets medical standards. When the detected blood pressure value exceeds the upper and lower blood pressure range, it can immediately feedback to the blood pressure measurement device 10 composed of the blood pressure measurement module of this case, and issue a warning notification, so as to better understand the physiological health status of the wearer.
[0112] The optical sensor 6a receives the light source reflected back after the emitted light source is transmitted to the skin tissue and generates a detection signal, achieving a photoelectric volumetric pulse wave (PPG) measurement principle, and provides it to the microprocessor 7 for conversion into health data information output, and this health data information can include a heart rate data, an electrocardiogram data and a blood pressure data. This optical measurement can also achieve a blood pressure measurement method. Although it can be measured at any time and every minute, the health data information obtained by monitoring is obtained through algorithm adjustment, and is not directly measured by an inflation-type measurement method. Therefore, it is not accurate enough. In view of this, the blood pressure measurement module of this case is particularly provided to be miniaturized and suitable for implementation on a wearable device to achieve an inflation-type blood pressure measurement method, so as to obtain an accurate blood pressure measurement value, and this measurement value can be used as an initial correction for the photoelectric measurement of blood pressure, and the heart rate variability (HeartRate Variability, HRV), and auxiliary confirmation of atrial fibrillation (AF); that is, when the optical sensor 6a starts the first measurement, the blood pressure measurement module of the present case is first implemented to implement the inflation-type blood pressure measurement method, and the health data information obtained is used as the calculation basis for the measurement correction of the optical sensor 6a, so that the optical sensor 6a can be compensated after each measurement to achieve a more accurate measurement of health data information output. In addition, when the wearer has a condition, such as fall detection, the three-axis acceleration sensor 6b can be used to detect the signal and directly transmit it to the microprocessor 7 to control the drive of the gas transmission device 2 to expand the airbag 4 for blood pressure measurement, and monitor the pressure of the gas accumulated in the airbag 4 through the sensor 3 to calculate the blood pressure information of the monitored user; or when the user's blood pressure and blood oxygen are abnormal, it can be sensed by the optical sensor 6a, and the microprocessor 7 receives the abnormal condition of the signal measured by the optical sensor 6a, directly controls the drive of the gas transmission device 2 to expand the airbag 4 for blood pressure measurement, and monitors the pressure of the gas accumulated in the airbag 4 or the pressure of contact with the user's skin through the sensor 3 to calculate the blood pressure information of the monitored user, providing more reliable data reference to understand the user's health information when a condition occurs, and can immediately notify or report the treatment measures of the rescue, which is of great value.
[0113] In this embodiment, the specific implementation of the blood pressure measuring device 10 constituted by the blood pressure measuring module of the present case can be controlled by the microprocessor 7 to automatically inflate and measure blood pressure once every 5 minutes to 60 minutes. The wearer can also set the blood pressure measuring device 10 by himself, store and record it for further analysis and statistics, so that the continuous blood pressure results can be displayed in a very convenient way for the wearer to operate, and the health status of the wearer can be better understood. At the same time, the blood pressure measuring module of the present case directly measures blood pressure by an inflatable method, combined with an optical blood pressure measurement method detected by an optical sensor 6a. The optical blood pressure measurement method can also be connected to a self-learning artificial intelligence (AI) program through an external connection device 9, which is responsible for 24-hour analysis and monitoring. If there is an abnormality, it will be fed back to the blood pressure measuring device 10 constituted by the blood pressure measuring module of the present case to start the driving of the gas transmission device 2 and inflate the air bag 4 to form an accurate blood pressure measurement operation, obtain correct blood pressure data information, and provide it to the wearer to understand the health status. If the obtained blood pressure data information is abnormal again, a warning notification can be issued in time, which is of great value.
[0114] In summary, the blood pressure measurement module provided in this case can be easily implemented in a blood pressure measurement device, and can obtain the most accurate blood pressure measurement value information by directly measuring blood pressure with an inflation method and calibrating it with an optical blood pressure measurement method detected by an optical sensor. It can also be connected to a self-learning artificial intelligence (AI) program through an external connection device, responsible for 24-hour analysis and monitoring, and has the functions of abnormal feedback and notification warning, which is extremely beneficial for industrial utilization.
[0115] This case can be modified in various ways by those familiar with this technology, but all of them will not deviate from the scope of protection sought by the attached patent application.
