Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of arterial hemostasis technology, and more specifically to arterial compression devices. Background Art

[0002] After arterial (e.g., radial or femoral artery) intervention, the rapid and strong arterial pulsation can lead to rapid and significant bleeding. Therefore, pressure bandaging of the puncture site is necessary. Currently, pressure bandaging of the puncture site is achieved by wrapping the site with elastic nursing gauze.

[0003] However, the inventors discovered that when applying pressure bandage to the puncture site using the above method, the following technical problems often arise:

[0004] Using elastic gauze for pressure bandaging makes it impossible to determine the appropriate pressure. If the pressure is insufficient, arterial bleeding may continue; if the pressure is too high, it may cause hematoma, peripheral nerve damage, pressure sores, and numbness and pain in the limbs. Furthermore, the complete wrapping also affects blood return, resulting in poor user safety.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background of the inventive concept, and therefore may contain information that does not form prior art known to those skilled in the art. Summary of the Invention

[0006] The summary portion of this disclosure is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description portion. This summary portion is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0008] Some embodiments of this disclosure provide an arterial compression device, comprising an inner ring and an outer ring. The inner ring contains a pressure application module, a support module, and a stabilizing module. These modules are arranged in a triangular configuration. When the device is worn, the pressure application module is positioned at the site of arterial bleeding, the support module is positioned to the side of the bleeding site, and the stabilizing module is positioned behind the bleeding site.

A roller is disposed between the outer ring and the inner ring. When the outer ring is fixed, the inner ring rotates with the compression point.

[0009] Optionally, the pressure application module includes a hemostatic contact block, and the pressure sensor and the humidity sensor are both disposed on the hemostatic contact block.

[0010] Optionally, the back of the pressure application module, the support module, and the stabilizing module are all provided with connectors; the inner ring is provided with elongated connecting holes at positions corresponding to the pressure application module, the support module, and the stabilizing module, the length of which is the movable length of the pressure application module, the support module, and the stabilizing module; when the pressure application module, the support module, and the stabilizing module are connected to the inner side of the inner ring, each connector can be movably connected to the elongated connecting hole corresponding to the connector.

[0011] Optionally, the aforementioned connector includes a controller and a motion control mechanism. The motion control mechanism includes a lead screw, a guide rail slider, and a micro motor. The output shaft of the micro motor is connected to one end of the lead screw via a coupling. The guide rail slider is connected to the base of the pressure module, the support module, or the stabilizing module via bolts. When the micro motor starts, the lead screw rotates to move the nut on the pressure module axially along the lead screw. The controller is communicatively connected to the pressure sensor and the humidity sensor. The controller is further configured to perform the following steps: acquiring current humidity information collected by the humidity sensor; determining the humidity difference between the current humidity information and the previous humidity information as the current humidity difference value; acquiring a historical humidity difference value sequence corresponding to the current humidity information, wherein the historical humidity difference value in the historical humidity difference value sequence can be the humidity difference corresponding to every two adjacent humidity information detected within a certain period; determining the average of each historical humidity difference value in the historical humidity difference value sequence as the historical average humidity difference value; and determining the absolute value of the difference between the current humidity difference value and the historical average humidity difference value as the current humidity change value. Determine whether the current humidity change value is greater than or equal to a preset humidity change threshold. In response to determining that the current humidity change value is greater than or equal to the preset humidity change threshold, acquire the pressure information detected by the pressure sensor. Based on the pressure information and the current humidity information, generate pressure adjustment information. Based on the pressure adjustment information, control each movement control mechanism to perform the movement operation corresponding to the pressure adjustment information.

[0012] Optionally, each connector includes a connecting rod, an inner nut, and an outer nut; one end of the connecting rod is fixed to the back of the pressure module, the support module, or the stabilizing module, and the other end of the connecting rod is threaded, with the inner nut and the outer nut slidably connected to the other end of the connecting rod via the thread; when the connector is connected to the corresponding elongated connecting hole, the other end of the connecting rod passes through the elongated connecting hole, the inner nut fits against the inner side of the inner ring, and the outer nut fits against the outer side of the inner ring.

[0013] Optionally, the inner ring is provided with a connecting rod fixing groove, and when the inner ring and the outer ring are fixedly connected, each connecting rod is embedded in the connecting rod fixing groove.

[0014] Optionally, the inner side of the outer ring is provided with an annular groove, and at least one roller is embedded in the annular groove. The outer edge of the inner ring is provided with a track corresponding to the annular groove.

[0015] Optionally, the outer ring is provided with a display device, which is communicatively connected to the pressure sensor and the humidity sensor. The display device is used to display the pressure detected by the pressure sensor and the humidity detected by the humidity sensor.

[0016] Optionally, the areas of the pressure module, the support module, and the stabilizing module that come into contact with the bleeding site are made of medical-grade silicone.

[0017] Optionally, both the pressure sensor and the humidity sensor described above are flexible piezoresistive thin-film sensors.

[0018] The various embodiments disclosed above have the following beneficial effects: the arterial compression device of some embodiments of this disclosure can improve user safety. Specifically, the reason why the segmentation results of the relevant segmentation model are not accurate enough is that: the pressure applied by wrapping with elastic nursing gauze cannot be determined. When the pressure is insufficient, the artery may continue to bleed; when the pressure is too high, it may cause hematoma, peripheral nerve damage, pressure sores, etc. at the puncture site, and may also cause limb numbness and pain; and the wrapping of the entire area also affects blood return. Based on this, some embodiments of the arterial compression device disclosed herein include an inner ring and an outer ring. The inner ring contains a pressure application module, a support module, and a stabilizing module. These modules are arranged in a triangular pattern. When the arterial compression device is worn, the pressure application module is located at the arterial bleeding site, the support module is located on the side of the bleeding site, and the stabilizing module is located on the back of the bleeding site. All three modules are slidably disposed within the inner ring. The pressure application module includes a pressure sensor and a humidity sensor. The outer ring includes an inner ring and an outer ring. The inner ring is connected to the inner ring and embedded within the outer ring. A roller is disposed between the outer ring and the inner ring. When the outer ring is fixed, the inner ring rotates with the compression point. Thus, by using the triangularly distributed pressure application module, support module, and stabilizing module to support the user's bleeding site, entanglement of the entire area can be avoided, thereby reducing the impact on blood return. Furthermore, the pressure sensor can detect the pressure applied to the artery by the aforementioned pressure module, allowing for the application of appropriate pressure to the artery. This ensures hemostasis while reducing the probability of hematoma formation at the puncture site, peripheral nerve damage, pressure sores, and limb numbness and pain. Therefore, the arterial compression device according to some embodiments of this disclosure can improve user safety. Attached Figure Description

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Figure 1 This is a schematic diagram of the structure of some embodiments of the arterial compression device according to the present disclosure. Figure 1 It includes an inner ring 1, an outer ring 2, a pressure application module 3, a support module 4, and a stabilization module 5.

[0031] Figure 2 This is a cross-sectional view of some embodiments of the arterial compression device according to the present disclosure. Figure 2 It includes an inner ring 1, an outer ring 2, a pressure application module 3, a support module 4, and a stabilizing module 5. The outer ring 2 includes an inner ring 21, an outer ring 22, and rollers 23.

[0032] Figure 3 This is a schematic diagram of the structure of some embodiments of the inner ring included in the arterial compression device according to the present disclosure. Figure 3 It includes an inner ring 1, a pressure module 3, a support module 4, a stabilizing module 5, a connector 6, and a long strip connecting hole 7.

[0033] In some embodiments, the arterial compression device may include an inner ring 1 and an outer ring 2. The inner ring 1 may contain a pressure application module 3, a support module 4, and a stabilizing module 5. The inner ring 1 may be a connecting ring that connects to the user's bleeding site. The outer ring 2 may be a fixing ring connected to the inner ring 1. The pressure application module 3 may be a component located at the arterial bleeding site for applying pressure to stop bleeding. The support module 4 may be a support block located on the side of the arterial bleeding site for stable support. The stabilizing module 5 may be a stabilizing block located on the back of the arterial bleeding site for stable support. For example, both the support module 4 and the stabilizing module 5 may be silicone blocks.

[0034] In some embodiments, the pressure application module 3, the support module 4, and the stabilizing module 5 can be arranged in a triangular pattern. When the arterial compression device is worn, the pressure application module 3 can be located at the site of arterial bleeding. The support module 4 can be located on the side of the site of arterial bleeding. The stabilizing module 5 can be located on the back of the site of arterial bleeding. Thus, the three-point support reduces pressure on the ulnar artery and external veins, greatly reducing the risk of blood flow obstruction.

[0035] In some embodiments, the pressure application module 3, the support module 4, and the stabilizing module 5 are all slidably disposed inside the inner ring 1. This means that the connection positions of the pressure application module 3, the support module 4, and the stabilizing module 5 with the inner ring 1 are adjustable. The pressure application module 3 may include a pressure sensor and a humidity sensor. Therefore, adjusting the positions of the pressure application module, the support module, and the stabilizing module according to the size of the user's bleeding site allows for more accurate arterial hemostasis pressure application. Furthermore, the pressure sensor and humidity sensor can determine the pressure applied to the artery by the pressure application module and whether bleeding is present, facilitating subsequent adjustment of the arterial compression device based on the pressure and bleeding status.

[0036] In some embodiments, the outer ring 2 may include an inner ring 21 and an outer ring 22. The inner ring 21 may be connected to the inner ring 1. The inner ring 21 may be embedded inside the outer ring 22. A roller 23 may be provided between the outer ring 22 and the inner ring 21. When the outer ring 22 is fixed, the inner ring 21 may rotate with the pressing part. Thus, by designing the outer ring as a double-ring structure, and allowing the inner and outer rings to rotate relative to each other, the rotation of the inner ring is not affected when the outer ring of the arterial compression device is braked under external force, thereby not affecting the movement of the patient's bleeding site and making it easier for the user to operate.

[0037] Optionally, the pressure application module 3 may include a hemostatic contact block. The hemostatic contact block may be a silicone block. Both the pressure sensor and the humidity sensor may be mounted on the hemostatic contact block. As an example, the pressure sensor and the humidity sensor may be respectively bonded to both ends of the surface of the hemostatic contact block that contacts the bleeding site.

[0038] In the process of adopting technical solutions to address the aforementioned technical problems, the following technical problem often arises: Arterial bleeding conditions vary at different times during arterial compression hemostasis, thus requiring different compression pressures. Using the same compression pressure for extended periods leads to poor hemostasis and a poor user experience. The conventional solution to this second technical problem is for nurses to manually adjust the pressure of the compression module to adapt to different arterial bleeding conditions. However, this conventional solution still suffers from the following issues: arterial hemostasis takes a long time, requiring multiple adjustments to the compression module's pressure; manual adjustment is cumbersome, resulting in a poor user experience.

[0039] Considering the problems with the conventional solutions mentioned above, and addressing the second technical issue—that arterial bleeding varies at different times during arterial compression for hemostasis, requiring different compression pressures, and that prolonged use of the same pressure results in poor hemostasis and a poor user experience—the following solution can be adopted based on the current technological situation:

[0040] Optionally, a connector 6 can be provided on the back of each of the pressure application module 3, the support module 4, and the stabilizing module 5. The connector 6 can be a component for connecting the pressure application module 3, the support module 4, or the stabilizing module 5 to the inner ring 1. An elongated connecting hole 7 can be provided on the inner ring 1 at the positions corresponding to the pressure application module 3, the support module 4, and the stabilizing module 5. The length of the elongated connecting hole 7 can be the movable length of the pressure application module 3, the support module 4, and the stabilizing module 5. The specific length of the elongated connecting hole 7 is not limited here. As an example, the length of the elongated connecting hole 7 can be 2 cm. When the pressure application module 3, the support module 4, and the stabilizing module 5 are connected to the inner side of the inner ring 1, each connector 6 can be movably connected to the elongated connecting hole 7 corresponding to the connector 6. Specifically, when the connector 6 moves within the elongated connecting hole 7, the pressure module 3, the support module 4, or the stabilizing module 5 connected to the connector 6 moves with the connector 6.

[0041] Optionally, the connecting component 6 may include a controller and a movement control mechanism. The controller may be a microcontroller that controls the movement of the pressure application module 3, the support module 4, or the stabilizing module 5. For example, the controller may be an STM32. The movement control mechanism may be a mechanism for driving the movement of the pressure application module 3, the support module 4, or the stabilizing module 5. The movement control mechanism may include a lead screw, a guide rail slider, and a micro motor. The output shaft of the micro motor may be connected to one end of the lead screw via a coupling. The guide rail slider may be connected to the base of the pressure application module 3, the support module 4, or the stabilizing module 5 via bolts. When the micro motor starts, the lead screw rotates to move the nut on the pressure application module 3 axially. Thus, the controller and the movement control mechanism can automatically control the movement of the pressure application module 3, the support module 4, or the stabilizing module 5 to adjust the pressure exerted by the pressure application module 3, the support module 4, or the stabilizing module 5 on the pressing part.

[0042] Optionally, the controller can be communicatively connected to the pressure sensor and the humidity sensor. The controller can also be configured to perform the following steps:

[0043] The first step is to acquire the current humidity information collected by the aforementioned humidity sensor. This humidity information can represent the current bleeding status at the arterial bleeding site.

[0044] The second step is to determine the current humidity difference as the humidity difference between the current humidity information and the previous humidity information. The previous humidity information can be humidity information acquired at a time point prior to or adjacent to the previous humidity information.

[0045] The third step is to obtain the historical humidity difference sequence corresponding to the current humidity information. The historical humidity difference in this sequence can be the humidity difference between two adjacent humidity values ​​detected within a given period. In practice, this historical humidity difference sequence can be obtained as follows: First, obtain the humidity information sequence collected by the humidity sensor. This sequence can include at least one humidity information. Each humidity information corresponds to a different time point. This humidity information sequence can be a set of information characterizing the bleeding situation at the arterial bleeding site detected within a previous period. Then, the humidity difference between two adjacent humidity values ​​in this sequence is determined as the historical humidity difference sequence.

[0046] The fourth step is to determine the mean of each historical humidity difference in the above historical humidity difference sequence as the historical average humidity difference.

[0047] The fifth step is to determine the absolute value of the difference between the current humidity difference and the historical average humidity difference as the current humidity change value.

[0048] Step 6: Determine whether the current humidity change value is greater than or equal to a preset humidity change threshold. The preset humidity change threshold can be a threshold that indicates abnormal arterial bleeding when the current humidity change value exceeds that threshold.

[0049] Step 7: In response to determining that the current humidity change value is greater than or equal to the preset humidity change threshold, obtain the pressure information detected by the pressure sensor.

[0050] Step 8: Based on the aforementioned pressure information and current humidity information, generate pressure adjustment information. This pressure adjustment information can be information representing the pressure that the pressurizing device needs to adjust. In practice, the controller can input the pressure information and humidity information into a pre-trained pressure adjustment information generation model to obtain the pressure adjustment information. This pressure adjustment information generation model can be a pre-trained machine learning model that takes pressure information and current humidity information as input and outputs the pressure adjustment information. For example, the pressure adjustment information generation model can be a random forest model. The pressure adjustment information generation model can include an input layer, a feature fusion layer, a decision layer, a safety constraint layer, and an output layer. The input layer can be used to extract features from the pressure information and current humidity information to obtain pressure feature information and humidity feature information. The feature fusion layer can fuse the pressure feature information and humidity feature information through a cross-modal attention mechanism to obtain feature fusion information. The decision layer can be used to classify the output based on the input feature fusion information to obtain pressurization information, depressurization information, or maintenance information. The aforementioned safety constraint layer can be used to constrain the obtained pressurization, depressurization, or holding information through a clamping function to obtain the pressure adjustment information. The aforementioned output layer is used to output the information to be adjusted. The aforementioned pressure adjustment information generation model can be trained on an initial model using historical pressure information and historical current humidity information, and the completion of training is determined by a loss function.

[0051] Step nine: Based on the pressure adjustment information, control each movement control mechanism to perform the movement operation corresponding to the pressure adjustment information. In practice, the controller can select the movement path information corresponding to the pressure adjustment information from a preset movement path information configuration table. This movement path information configuration table can be a table representing the correspondence between the pressure adjustment information and the movement path information. For example, when the pressure adjustment information is +2 mmHg, the movement path information could be a downward movement of 2 mm. The movement path information can include the path required for each movement control mechanism to move. Then, the controller can control each movement control mechanism to move according to the movement path information.

[0052] The aforementioned content regarding controlling the movement of various motion control mechanisms based on humidity and pressure information serves as an inventive point of this disclosure, solving technical problem two: "During different time periods of arterial pressure hemostasis, the arterial bleeding condition varies, thus requiring different pressure levels. Prolonged use of the same pressure level results in poor hemostasis and a poor user experience." The reasons for this poor hemostasis and user experience are as follows: Different time periods of arterial pressure hemostasis require different pressure levels; prolonged use of the same pressure level results in poor hemostasis and a poor user experience. Solving these factors can improve both hemostasis and user experience. To achieve this effect, the arterial compression device of this disclosure includes connecting members on the back of the pressure application module, the support module, and the stabilizing module. Elongated connecting holes are provided on the inner ring at positions corresponding to the pressure application module, the support module, and the stabilizing module, with the length of the connecting holes being the movable length of the pressure application module, the support module, and the stabilizing module. When the pressure application module, the support module, and the stabilizing module are connected to the inner side of the inner ring, each connecting member is movably connected to the corresponding elongated connecting hole. The connecting members include a controller and a movement control mechanism. The movement control mechanism includes a lead screw, a guide rail slider, and a micro motor. The motor output shaft of the micro motor is connected to one end of the lead screw via a coupling. The guide rail slider is connected to the base of the pressure application module, the support module, or the stabilizing module via bolts. When the micro motor is started, the lead screw rotates to drive the nut on the pressure application module to move axially along the lead screw. The controller is communicatively connected to the pressure sensor and the humidity sensor. The controller is further configured to perform the following steps: acquire current humidity information collected by the humidity sensor; determine the humidity difference between the current humidity information and the previous humidity information as the current humidity difference value; acquire a historical humidity difference value sequence corresponding to the current humidity information, wherein the historical humidity difference value in the historical humidity difference value sequence can be the humidity difference corresponding to every two adjacent humidity information detected within a certain period of time; determine the average of each historical humidity difference value in the historical humidity difference value sequence as the historical average humidity difference value; determine the absolute value of the difference between the current humidity difference value and the historical average humidity difference value as the current humidity change value; determine whether the current humidity change value is greater than or equal to a preset humidity change threshold; in response to determining that the current humidity change value is greater than or equal to the preset humidity change threshold, acquire pressure information detected by the pressure sensor; generate pressure adjustment information based on the pressure information and the current humidity information; and control each movement control mechanism to perform movement operations corresponding to the pressure adjustment information based on the pressure adjustment information.Therefore, the controller and the movement control mechanism can automatically control the movement of the pressure application module, the support module, or the stabilizing module to adjust the pressure applied to the pressure point. Furthermore, the controller can acquire pressure information detected by the pressure sensor and humidity information detected by the humidity sensor, and based on this information, determine the bleeding status at the artery site. This allows the movement control mechanism to adjust the pressure applied to the pressure application module, the support module, or the stabilizing module to better suit the user's needs, thereby improving hemostasis and user experience.

[0053] In addressing the aforementioned technical problems using technical solutions, the following third technical issue often arises: A patient's age, weight, vascular condition, blood pressure level, and other individual factors influence arterial bleeding. Therefore, patients with different physical conditions require different pressure applications. For some patients with unique physical conditions, applying a uniform pressure may result in poor hemostasis, leading to a poor user experience. The conventional solution to this third technical problem is for nurses to observe the patient's specific condition and manually adjust the pressure accordingly. However, this conventional solution still has the following drawback: For patients in poor physical condition, it is necessary to constantly monitor their physical changes and adjust the pressure in a timely manner during hemostasis. Nurses typically cannot be with the patient at all times to observe various physical data and adjust the pressure accordingly, resulting in a poor user experience.

[0054] Considering the problems with the conventional solutions mentioned above, and addressing the third technical issue—that patients' age, weight, vascular condition, blood pressure levels, and other individual factors influence arterial bleeding—different pressures are required for patients with different physical conditions. Using a uniform pressure for some patients with unique physical circumstances may result in poor hemostasis and a poor user experience. Based on the current technological situation, the following solution can be adopted:

[0055] Optionally, the arterial compression device further includes a communication module and a triaxial sensor. The communication module can be WiFi. The triaxial sensor can be a triaxial accelerometer or a triaxial gyroscope. The controller can communicate with the communication module, the triaxial sensor, the pressure sensor, and the humidity sensor. The controller can also be configured to perform the following steps:

[0056] The first step is to receive patient information and hemostasis scenario information sent by the associated smart device. The patient information may include at least one of the following: age, weight, blood pressure, and vascular disease history. The hemostasis scenario information may be for postoperative hemostasis, emergency hemostasis, or long-term use of a hemostatic agent. The smart device may be a mobile phone or a computer.

[0057] The second step involves inputting the aforementioned patient information and hemostasis scenario information into a pre-trained baseline pressure information generation model to obtain baseline pressure information. This baseline pressure information can represent the initially set compression pressure. The baseline pressure information generation model can be a pre-trained machine learning model that takes patient information and hemostasis scenario information as input and baseline pressure information as output. For example, the baseline pressure information generation model can be a decision tree model. This model can include a patient information feature extraction sub-model, a hemostasis scenario information feature extraction sub-model, a cross-modal attention fusion sub-model, and a pressure prediction sub-model. The patient information feature extraction sub-model can include a fully connected layer and an attention mechanism layer for feature extraction of patient information. The hemostasis scenario information feature extraction sub-model can include an embedding layer and a gating mechanism layer for feature extraction of hemostasis scenario information. The cross-modal attention fusion sub-model can be used to fuse patient feature information and hemostasis scenario feature information through a cross-modal attention mechanism. The aforementioned pressure prediction sub-model may include a fully connected layer and an activation function layer, used to predict basic pressure information based on the fused information.

[0058] The third step involves controlling each movement control mechanism to perform movement operations corresponding to the aforementioned basic pressure information, based on the basic pressure information. In practice, the controller can select movement path information corresponding to the basic pressure information from a preset movement path information configuration table. This movement path information configuration table can represent both the basic pressure information and the movement path information. The movement path information can include the path required for each movement control mechanism to move. For example, when the basic pressure information is 20 mmHg, the movement path information could be that the guide rail slider moves to a position 4 mm from its initial position. Then, the controller can control each movement control mechanism to move according to the aforementioned movement path information.

[0059] The fourth step is to obtain the acceleration information set collected by the triaxial sensor. This acceleration information set can be a sequence of acceleration information collected over a period of time.

[0060] The fifth step involves performing motion detection on each acceleration information in the aforementioned acceleration information set to obtain motion detection results. These results can indicate whether the user is in a moving or stationary state. In practice, the controller can use a frequency domain analysis algorithm to perform motion detection on each acceleration information in the aforementioned acceleration information set to obtain motion detection results. As an example, the controller can extract the dominant frequency of the acceleration information set using Fourier transform. Then, the controller can determine the motion detection result based on the dominant frequency. For example, the dominant frequency for a stationary state can be 0-1Hz, while the dominant frequency for a moving state can be 2-4Hz.

[0061] Step 6: In response to determining that the above motion detection results indicate that the user is in motion, acquire the pulse information and blood oxygen information collected by the associated pulse oximeter. The pulse oximeter is communicatively connected to the controller.

[0062] Step 7: Based on the pulse and blood oxygen information, generate pressure adjustment information. This pressure adjustment information can represent the pressure that the pressure application device needs to adjust. In practice, the controller can input the pulse and blood oxygen information into a pre-trained pressure adjustment information generation model to obtain the pressure adjustment information. This pressure adjustment information generation model can be a pre-trained machine learning model that takes pulse and blood oxygen information as input and outputs pressure adjustment information. For example, the pressure adjustment information generation model can be a random forest model.

[0063] Step 8: Based on the pressure adjustment information mentioned above, control each movement control mechanism to perform the movement adjustment operation corresponding to the pressure adjustment information mentioned above.

[0064] The aforementioned content regarding controlling various motion control mechanisms to perform motion adjustment operations based on pulse and blood oxygen information is an inventive point of this disclosure, addressing technical problem three: "A patient's age, weight, vascular condition, blood pressure level, and other personal factors have a certain impact on the patient's arterial bleeding. Therefore, patients with different physical conditions require different pressure applications. For some patients with special physical conditions, using a uniform pressure application may lead to poor hemostasis, resulting in a poor user experience." The reasons for the poor user experience are as follows: A patient's age, weight, vascular condition, blood pressure level, and other personal factors have a certain impact on the patient's arterial bleeding. Therefore, patients with different physical conditions require different pressure applications. For some patients with special physical conditions, using a uniform pressure application may lead to poor hemostasis. Solving these factors can improve the user experience. To achieve this effect, the arterial compression device of this disclosure includes connecting members on the back of the pressure application module, the support module, and the stabilizing module; elongated connecting holes are provided on the inner ring at positions corresponding to the pressure application module, the support module, and the stabilizing module, with the length of the elongated connecting holes being the movable length of the pressure application module, the support module, and the stabilizing module; when the pressure application module, the support module, and the stabilizing module are connected to the inner side of the inner ring, each connecting member is movably connected to the elongated connecting hole corresponding to the connecting member. The connecting members include a controller and a movement control mechanism. The movement control mechanism includes a lead screw, a guide rail slider, and a micro motor. The motor output shaft of the micro motor is connected to one end of the lead screw via a coupling. The guide rail slider is connected to the base of the pressure application module, the support module, or the stabilizing module via bolts. When the micro motor is started, the lead screw rotates to drive the nut on the pressure application module to move axially along the lead screw. The arterial compression device also includes a communication module and a triaxial sensor. The controller is communicatively connected to the communication module, the triaxial sensor, the pressure sensor, and the humidity sensor. The controller can also be configured to perform the following steps: receiving patient information and hemostasis scenario information sent by the associated smart device; inputting the patient information and hemostasis scenario information into a pre-trained baseline pressure information generation model to obtain baseline pressure information; controlling each motion control mechanism to perform a movement operation corresponding to the baseline pressure information based on the baseline pressure information; acquiring the acceleration information set collected by the triaxial sensor; performing motion detection on each acceleration information in the acceleration information set to obtain motion detection results. The motion detection results can characterize whether the user is in a moving or stationary state. In practice, the control can use a frequency domain analysis algorithm to perform motion detection on each acceleration information in the acceleration information set to obtain motion detection results.In response to the determination that the aforementioned motion detection results indicate that the user is in motion, pulse and blood oxygen information collected by a related pulse oximeter are acquired. The pulse oximeter is communicatively connected to the controller. Pressure adjustment information is generated based on the pulse and blood oxygen information. Based on this pressure adjustment information, each motion control mechanism is controlled to perform a corresponding motion adjustment operation. Therefore, by using patient information and hemostasis scenario information, a more suitable compression pressure can be set for the patient, thereby improving the user experience. Furthermore, the triaxial sensor can determine the patient's motion state, and when the patient is in motion, the patient's pulse and blood oxygen are collected to adjust the pressure, making the compression pressure more suitable for the patient's current state, improving hemostasis, and thus enhancing the patient's user experience.

[0071] The various embodiments disclosed above have the following beneficial effects: the arterial compression device of some embodiments of this disclosure can improve user safety. Specifically, the reason why the segmentation results of the relevant segmentation model are not accurate enough is that: the pressure applied by wrapping with elastic nursing gauze cannot be determined. When the pressure is insufficient, the artery may continue to bleed; when the pressure is too high, it may cause hematoma, peripheral nerve damage, pressure sores, etc. at the puncture site, and may also cause limb numbness and pain; and the wrapping of the entire area also affects blood return. Based on this, some embodiments of the arterial compression device disclosed herein include an inner ring and an outer ring. The inner ring contains a pressure application module, a support module, and a stabilizing module. These modules are arranged in a triangular pattern. When the arterial compression device is worn, the pressure application module is located at the arterial bleeding site, the support module is located on the side of the bleeding site, and the stabilizing module is located on the back of the bleeding site. All three modules are slidably disposed within the inner ring. The pressure application module includes a pressure sensor and a humidity sensor. The outer ring includes an inner ring and an outer ring. The inner ring is connected to the inner ring and embedded within the outer ring. A roller is disposed between the outer ring and the inner ring. When the outer ring is fixed, the inner ring rotates with the compression point. Thus, by using the triangularly distributed pressure application module, support module, and stabilizing module to support the user's bleeding site, entanglement of the entire area can be avoided, thereby reducing the impact on blood return. Furthermore, the pressure sensor can detect the pressure applied to the artery by the aforementioned pressure module, allowing for the application of appropriate pressure to the artery. This ensures hemostasis while reducing the probability of hematoma formation at the puncture site, peripheral nerve damage, pressure sores, and limb numbness and pain. Therefore, the arterial compression device according to some embodiments of this disclosure can improve user safety.
