Description

Technical Field

[0001] This invention relates to a pressure application method, particularly an automatically controlled pressure application method. Background Technology

[0002] Existing automatic pressure control methods require multiple sets of motors to control the measurement depth and pressure of multiple sensors. However, this results in higher costs and greater complexity in the design of the control method. Summary of the Invention

[0003] In view of this, according to one embodiment, an automatic pressure adjustment method is provided to obtain multi-point pulse pressure of the test object. The automatic pressure adjustment method includes controlling multiple electromagnets of a pressure adjustment module to attract a corresponding fine adjustment column with an attraction force; driving a drive unit to move the pressure adjustment module so that the multiple fine adjustment columns apply pressure to the test object; continuously reading the pressure measured by a sensing module set at the end of each fine adjustment column; and when one of the multiple sensing modules measures a pressure greater than or equal to a set value, reducing the attraction force of the electromagnet of the fine adjustment column corresponding to the sensing module whose measured pressure is greater than or equal to the set value on the fine adjustment column.

[0004] In some embodiments, each fine adjustment column is suspended and released in front of the corresponding fine adjustment column attracted by multiple electromagnets. The processing unit controls the driving unit to move the pressure adjustment module until each fine adjustment column is attached to the surface of the object to be tested, so as to complete the positioning.

[0005] In some embodiments, each fine-tuning column is attached to the surface of the object to be measured until a pressure threshold measured by each sensing module is approximately 60 mmHg. Then, the driving unit is driven to move the pressure adjustment module so that the pressure threshold measured by each sensing module is approximately 20 mmHg.

[0006] In some embodiments, each fine-tuning bar is attached to the surface of the object to be measured until a pressure threshold measured by each sensing module is approximately 5 mmHg.

[0007] In some embodiments, the pressure adjustment module continues to move until the pressure measured by each sensing module is greater than or equal to a set value.

[0008] In some embodiments, the adsorption force of the fine-tuning column corresponding to each electromagnet adsorption is 100%.

[0009] In some embodiments, the adsorption force of each electromagnet adsorbing the corresponding fine adjustment column is 50%. In the step of continuously reading the pressure measured by the sensing module set at the end of each fine adjustment column, when the increase ratio of the pressure measured by one of the multiple sensing modules and the distance moved by the pressure adjustment module is lower than a preset ratio value, the adsorption force of the electromagnet corresponding to the sensing module that is lower than the preset ratio value on the fine adjustment column is increased.

[0010] In some embodiments, the adsorption force of each electromagnet adsorbing the corresponding fine adjustment column is 50%. In the step of continuously reading the pressure measured by the sensing module set at the end of each fine adjustment column, when the increase ratio of the pressure measured by one of the multiple sensing modules and the distance moved by the pressure adjustment module is lower than a preset ratio value, the adsorption force of the electromagnet corresponding to the other sensing modules other than the sensing module that is lower than the preset ratio value on the fine adjustment column is reduced.

[0011] In some embodiments, the set value is 200 mmHg.

[0012] In summary, an automatic pressure adjustment method is provided according to one embodiment. A single drive unit controls the pressure adjustment module, and the fine-tuning column of the pressure adjustment module can also be fine-tuned by a corresponding electromagnet to control the pressure when the sensing module presses down. Thus, it is not necessary to configure a motor for each fine-tuning column, and the operation method is also simpler. Attached Figure Description

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0037] Please see Figures 1 to 3 . Figure 1 This is a perspective view of an automatic pressure regulating device according to a first embodiment. Figure 2 This is a schematic diagram of the movement of an automatic pressure regulating device according to a first embodiment. Figure 3This is a schematic diagram of an automatically adjustable pressure device according to a first embodiment. The automatically adjustable pressure device 100 includes a processing unit 110, a pressure adjustment module 130, a drive unit 150, and a plurality of sensing modules 170. The automatically adjustable pressure device 100 is used, for example, in a pulse diagnosis device, adjusting the position and applying pressure through the pressure adjustment module 130 and the drive unit 150, and detecting the pulse through the sensing modules 170.

[0038] The pressure adjustment module 130 is electrically connected to the processing unit 110. The pressure adjustment module 130 includes multiple fine-tuning posts 131 and multiple electromagnets 132. Each electromagnet 132 is configured to attract a corresponding fine-tuning post 131. Figure 1 As shown, there are three fine adjustment columns 131, namely fine adjustment columns 131A, 131B and 131C. There are also three electromagnets 132 corresponding to the fine adjustment columns 131, namely electromagnets 132A, 132B and 132C.

[0039] The drive unit 150 is electrically connected to the processing unit 110 and drives the pressure adjustment module 130 to move. In the first embodiment, the drive unit 150 is, for example, a screw motor assembly.

[0040] Multiple sensing modules 170 are electrically connected to the processing unit 110, and each sensing module 170 is correspondingly disposed at the end of the fine-tuning post 131. In the first embodiment, there are also three sensing modules 170 corresponding to the fine-tuning post 131, namely sensing modules 170A, 170B, and 170C. In the first embodiment, each sensing module 170A, 170B, and 170C is formed by arranging multiple piezoelectric sensors in an array.

[0041] Please see Figure 1 , Figure 3 and Figures 4 to 7 . Figure 4 This is a schematic diagram (a) of the use of an automatic pressure regulating device according to a first embodiment. Figure 5 This is a schematic diagram (II) of the use of the automatic pressure regulating device according to a first embodiment. Figure 6 This is a schematic diagram (III) of the use of an automatic pressure regulating device according to a first embodiment. Figure 7 A flowchart (a) illustrating the use of an automatic pressure control method according to a first embodiment is provided. Furthermore, Figures 4 to 6The left side, i.e., the position of the fine-tuning column 170A, is closer to the palm. The processing unit 110 controls the pressure adjustment module 130 to cause multiple electromagnets 132A, 132B, and 132C to attract the corresponding fine-tuning columns 131A, 131B, and 131C with an attractive force. The processing unit 110 also controls the drive unit 150 to move the pressure adjustment module 130, causing multiple sensing modules 170A, 170B, and 170C to apply pressure to the object B being measured. Subsequently, when one of the sensing modules 170A, 170B, and 170C measures a pressure greater than or equal to a set value, the processing unit 110 controls the pressure adjustment module 130 to reduce the attractive force of the electromagnet 132 on the fine-tuning column 131 corresponding to the sensing module 170 with a pressure greater than or equal to the set value.

[0042] In the first embodiment, as Figure 2 As shown, the object to be tested, B, is, for example, a human wrist. Specifically, the processing unit 110 drives the pressure adjustment module 130 to move via the drive unit 150, causing multiple sensing modules 170A, 170B, and 170C to apply pressure to the object to be tested, B, to obtain pressure data from the fine-tuning column 131 applied to the wrist, until the desired set value is obtained. Although each fine-tuning column 131 moves downward at the same speed under the drive of the drive unit 150, the depth to which each fine-tuning column 131 can press down after contacting the object to be tested, may differ due to the different bone and muscle configurations at different parts of the wrist. For example, if the sensing module 170 presses on the wrist bone and the muscle respectively, the sensing module 170 pressing on the wrist bone may measure a pressure equal to or greater than the set value after pressing down a shorter distance. In other words, the time and distance required for each sensing module 170A, 170B, and 170C to measure the data up to the set value may also be different. Furthermore, when the pressure of one of the sensing modules 170 is greater than or equal to the set value, the other two fine-tuning columns 131 will find it difficult to continue applying pressure due to the excessive pressure and the fact that the required set value has been reached, causing the sensing module 170 to be unable to perform measurements smoothly.

[0043] Therefore, as Figure 6 As shown, when the pressure measured by the sensing module 170A is greater than or equal to the set value, the excessive pressure prevents the fine-tuning columns 131B and 131C from continuing to press down, allowing the sensing modules 170B and 170C to take measurements. At this time, the processing unit 110 controls the attraction force of the electromagnet 132A that is attached to the fine-tuning column 131A. By reducing the attraction force of the electromagnet 132A on the fine-tuning column 131A, the fine-tuning column 131A can slide upwards relatively, allowing the fine-tuning columns 131B and 131C to continue to apply downward pressure under the drive of the driving unit 150, so that the sensing modules 170B and 170C can take measurements until the set value is reached.

[0044] Thus, by controlling the pressure adjustment module 130 to continuously apply pressure through a single drive unit 150, the fine-tuning columns 131A, 131B, and 131C of the pressure adjustment module 130 can fine-tune the adsorption force during the pressure application process using corresponding electromagnets 132A, 132B, and 132C. This prevents the other fine-tuning columns 131 from failing to complete their pulse pressure measurement because one of the fine-tuning columns 131 equipped with the sensing module 170 completes its stroke first due to its shorter stroke. Furthermore, the automatic pressure adjustment device 100 simplifies the structure of the device and makes it easier to operate.

[0045] In the first embodiment, the pressure adjustment module 130 further includes a main body 133, a plurality of fine-tuning posts 131A, 131B, 131C, and a plurality of electromagnets 132A, 132B, 132C disposed on the main body 133. As the main body 133 moves, the electromagnets 132A, 132B, 132C attract the corresponding fine-tuning posts 131A, 131B, 131C with an attractive force, causing each fine-tuning post 131A, 131B, 131C to be fixed or moved relative to the main body 133 according to changes in the attractive force of the electromagnets 132A, 132B, 132C. In the first embodiment, the plurality of fine-tuning posts 131A, 131B, 131C are movably inserted through the main body 133. Figure 1 and Figure 2 As shown, the driving unit 150 drives the main body 133 to move, and simultaneously moves multiple fine-tuning posts 131A, 131B, 131C and multiple electromagnets 132A, 132B, 132C disposed on the main body 133. The multiple fine-tuning posts 131A, 131B, 131C are fixed relative to the main body 133 by being attracted by the multiple electromagnets 132A, 132B, 132C. Figure 6 As shown, taking the fine-tuning column 131A as an example, when the electromagnet 132A reduces the adsorption force of the corresponding fine-tuning column 131A, as the main body 133 continues to press down, the fine-tuning column 131A will move relative to the main body 133 due to the weakening adsorption force and being pushed upward by the test object B.

[0046] In the first embodiment, the distance between each fine-tuning post 131A, 131B, and 131C is 1 mm, that is, the distance d between one fine-tuning post 131 and another fine-tuning post 131. Figures 4 to 6 As shown, in order to effectively measure the pulse pressure at various positions of the test object B, each fine adjustment column 131A, 131B, and 131C is set at a certain interval d.

[0047] For information on methods for automatically adjusting pressure, please refer again. Figures 4 to 7 An automatic pressure adjustment method is used to obtain multi-point pulse pressure of the test subject B.

[0048] like Figure 4 and Figure 7As shown, the automatic pressure adjustment method includes controlling multiple electromagnets 132A, 132B, and 132C of the pressure adjustment module 130 to adsorb a corresponding fine-tuning column 131A, 131B, or 131C with an adsorption force (step S10). In the first embodiment, each electromagnet 132A, 132B, and 132C adsorbs a corresponding fine-tuning column 131A, 131B, or 131C with a 100% adsorption force, but this is not the only possibility; other settings regarding the adsorption force will be detailed later.

[0049] Next, as Figure 5 and Figure 7 As shown, the drive unit 150 moves the pressure adjustment module 130, causing multiple fine-tuning columns 131A, 131B, and 131C to apply pressure to the test object B (step S11). In the first embodiment, the drive unit 150 moves the pressure adjustment module 130 toward the test object B and applies pressure at a rate of, for example, 0.3 mm / sec.

[0050] like Figure 5 and Figure 7 As shown, the pressure measured by a sensing module 170A, 170B, 170C located at the ends of each fine-tuning column 131A, 131B, 131C is continuously read (step S12). That is, as the drive unit 150 continuously moves the pressure adjustment module 130 to apply pressure to the test object B, the pressure is continuously measured by each sensing module 170A, 170B, 170C.

[0051] Furthermore, such as Figure 6 and Figure 7 As shown, if one of the multiple sensing modules 170A, 170B, and 170C measures a pressure greater than or equal to a set value, the electromagnet 132 of the fine-tuning column 131 corresponding to the sensing module 170 whose measured pressure is greater than or equal to the set value is reduced (step S13). Figure 6 As shown, when the pressure measured by the sensing module 170A is greater than or equal to the set value, the corresponding electromagnet 132A reduces the adsorption force on the corresponding fine-tuning column 131A, causing the fine-tuning column 131A to change from a fixed state to a relatively movable state. As the driving unit 150 continues to drive the pressure adjustment module 130 downward, the fine-tuning column 131A, due to the weakened adsorption force, is pushed upward by the object to be measured B and moves relative to it. In this way, the pressure adjustment module 130 continues to move, allowing the other fine-tuning columns 131B and 131C to complete their strokes. In the first embodiment, the set value is, for example, 200 mmHg.

[0052] Please see Figures 8 to 10 . Figure 8 This is a schematic diagram (a) of the positioning of an automatic pressure regulating device according to a first embodiment. Figure 9This is a positioning schematic diagram (II) of an automatic pressure regulating device according to a first embodiment. Figure 10 This is a flowchart illustrating the positioning process of an automatic pressure-regulating device according to a first embodiment. Furthermore, Figures 8 to 9 The left side, i.e., the position of the fine adjustment column 170A, is closer to the palm. Since the surface of the test object B is the wrist, it will be uneven depending on the individual. Therefore, before performing the aforementioned measurement, the fine adjustment columns 131 in the pressure adjustment module 130 can be positioned as the reference starting point for subsequent measurements. In the first embodiment, in front of the multiple electromagnets 132A, 132B, 132C adsorbing the corresponding fine adjustment columns 131A, 131B, 131C, each fine adjustment column 131A, 131B, 131C is in a suspended and released state (step S8). The processing unit 110 controls the driving unit 150 to move the pressure adjustment module 130 until each fine adjustment column 131A, 131B, 131C is in contact with the surface of the test object B (step S9) to complete the positioning. In addition, Figure 1 and Figure 2 Automatic pressure adjustment device 100 in the position of completed positioning.

[0053] like Figure 8 As shown, before the electromagnets 132A, 132B, and 132C are used to attach and fix the fine-tuning columns 131A, 131B, and 131C, the fine-tuning columns 131A, 131B, and 131C are positioned in a suspended, released state. At this time, the drive unit 150 drives the pressure adjustment module 130, causing each fine-tuning column 131A, 131B, and 131C to move downwards until it contacts the surface of the object to be measured, B. To accommodate the uneven surface of the wrist and ensure a consistent starting reference for subsequent measurements, the state in which the fine-tuning columns 131A, 131B, and 131C are in contact with the object to be measured, means that the sensing modules 170A, 170B, and 170C, which press the front ends of each fine-tuning column 131A, 131B, and 131C against the surface of the object to be measured, all measure the same pressure value. For example, a pressure threshold measured by each sensing module 170A, 170B, and 170C is approximately 5 mmHg. At this point, electromagnets 132A, 132B, and 132C can be activated to attract and position the fine-tuning columns 131A, 131B, and 131C.

[0054] In other words, in the first embodiment, each sensing module 170A, 170B, and 170C starts measuring with a pressure threshold of 5 mmHg, and the pressure adjustment module 130 continues to move until the pressure measured by each sensing module 170A, 170B, and 170C is greater than or equal to the set value, thus completing the pulse pressure measurement. Here, although the pressure threshold measured by each sensing module 170A, 170B, and 170C at the time of positioning is 5 mmHg, it is not limited to this.

[0055] Please see Figure 11 . Figure 11 This is a flowchart illustrating the positioning process of an automatic pressure adjustment device according to a second embodiment. The second embodiment differs from the first embodiment in the positioning method. To facilitate smoother subsequent measurements and avoid excessive measurement time, a certain pressure can be applied before starting the measurement. In this embodiment, during positioning, the processing unit 110 controls the drive unit 150 to move the pressure adjustment module 130 until each of the fine-tuning columns 131A, 131B, and 131C is in contact with the surface of the object to be measured, B (step S9A). At this time, the processing unit 110 controls one of the electromagnets 132A, 132B, and 132C to attract and position the corresponding fine-tuning column 131A, 131B, or 131C (step S9B). For example, Figure 9 The position of the test object B corresponding to the fine-tuning column 131C has a lot of muscle tissue, so a longer stroke is required to successfully measure the pressure. In order to determine the starting position of pressure application, the processing unit 110 first controls the electromagnet 132C to attract the fine-tuning column 131C, while the other fine-tuning columns 131A and 131B remain suspended. Next, the processing unit 110 controls the drive unit 150 to drive the pressure adjustment module 130 to move each fine-tuning column 131A, 131B, and 131C until the pressure threshold measured by the sensing module 170C is approximately 60 mmHg (step S9C). Next, the processing unit 110 controls the electromagnets 132A and 132B to attract the fine adjustment columns 131A and 131B, and causes the drive unit 150 to drive the pressure adjustment module 130 to move slightly upward, so that the pressure threshold measured by each sensing module 170A, 170B and 170C is about 20 mmHg (step S9D), so as to complete the positioning and provide pre-pressure.

[0056] Furthermore, in the aforementioned first embodiment, each electromagnet 132A, 132B, 132C adsorbs its corresponding fine-tuning column 131A, 131B, 131C with 100% adsorption force, but is not limited thereto. In the third embodiment, the adsorption force of each electromagnet 132A, 132B, 132C adsorbing its corresponding fine-tuning column 131A, 131B, 131C is 50%. In the step of continuously reading the pressure measured by the sensing modules 170A, 170B, 170C located at the ends of each fine-tuning column 131A, 131B, 131C, if the increase ratio of the pressure measured by one of the multiple sensing modules 170A, 170B, 170C and the distance moved by the pressure adjustment module 130 is lower than a preset ratio value, the adsorption force of the electromagnet 132 corresponding to the sensing module 170 that is lower than the preset ratio value on the fine-tuning column 131 is increased.

[0057] In other words, in the third embodiment, in step S10, electromagnets 132A, 132B, and 132C partially attract the fine-tuning columns 131A, 131B, and 131C with their attraction force. However, due to the relatively weak attraction force, the fine-tuning columns 131A, 131B, and 131C are prone to relative sliding when pressure is applied to the test object B to a certain extent. While this allows the fine-tuning columns 131A, 131B, and 131C to complete their stroke more smoothly and provides a certain degree of safety by preventing excessive pressure from being applied to the test object B, it may also lead to a low ratio of the measured pressure to the moving distance, affecting the measurement. Therefore, when the ratio of the increase is lower than a preset ratio value, the attraction force of the electromagnet 132 corresponding to the sensing module 170 below the preset ratio value on the fine-tuning column 131 is increased to make the fine-tuning column 131 less prone to relative movement due to pressure. In the third embodiment, adjustment is made when the ratio of the increase is lower than the preset ratio value by 10%.

[0058] The third embodiment adjusts the attraction force of the electromagnet 132 corresponding to the sensing module 170, which is lower than a preset ratio, to the fine-tuning column 131. However, this is not the only embodiment. In the fourth embodiment, the attraction force of the electromagnet 132 corresponding to other sensing modules 170, other than the sensing module 170, corresponding to the preset ratio, to the fine-tuning column 131 can also be reduced. For example, when the rise ratio of sensing module 170A is lower than the preset ratio, other sensing modules 170B and 170C are adjusted instead of sensing module 170A. By reducing the attraction force of the electromagnets 132B and 132C corresponding to sensing modules 170B and 170C to the fine-tuning columns 131B and 131C, when the pressure adjustment module 130 moves and applies pressure, the fine-tuning columns 131B and 131C, which receive a smaller attraction force, move relatively first, allowing the sensing module 170A to perform measurements smoothly. In the fourth embodiment, adjustment is made when the rise ratio is lower than 10% of the preset ratio.

[0059] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
