Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of arterial hemostasis, and more particularly to an arterial compression device. Background Art

[0002] After arterial intervention (such as radial artery or femoral artery), due to the fast pulsation speed and high intensity of the artery, the bleeding speed will be extremely fast and the bleeding volume will be extremely large. Therefore, pressure dressing needs to be applied to the puncture site. Currently, the method of applying pressure dressing to the puncture site is to use elastic nursing gauze to wrap around for pressure dressing.

[0003] However, the inventors found that when applying pressure dressing to the puncture site in the above manner, the following technical problems often exist: When using elastic nursing gauze to wrap around for pressure dressing, the pressing pressure cannot be determined. When the pressure is insufficient, the artery may continue to bleed; when the pressure is too high, it will cause hematoma formation, peripheral nerve injury, pressure sores, etc. at the puncture site, and limb numbness and pain may also occur; moreover, the wrapping of the entire site also affects blood return, resulting in poor user safety.

[0017] The above-described various embodiments of the present disclosure have the following beneficial effects: The arterial pressing device according to some embodiments of the present disclosure can improve the safety of user use. Specifically, the reason for the inaccurate segmentation results of the related segmentation model is that when using elastic nursing gauze to wrap and apply pressure dressing, it is impossible to determine the pressing pressure. When the pressure is insufficient, the artery may continue to bleed; when the pressure is too high, it will cause hematoma formation at the puncture site, peripheral nerve injury, pressure sores, etc., and limb numbness and pain may also occur; and the wrapping of the entire site also affects blood return.

When the outer circle is fixed, the inner circle rotates with the pressing site. Thus, by using the pressing module, the supporting module, and the stabilizing module distributed in a triangular shape to support the user's bleeding site, it is possible to avoid wrapping the entire site, thereby reducing the impact on blood return. And through the pressure sensor, the pressing pressure of the pressing module on the artery can be detected, so that an appropriate pressure can be used to press the artery, while ensuring the hemostasis of the artery, reducing the probability of hematoma formation at the puncture site, peripheral nerve injury, pressure sores, and limb numbness and pain. Therefore, the arterial pressing device according to some embodiments of the present disclosure can improve the safety of user use. Description of the Drawings

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Figure 1 It is a schematic structural diagram of some embodiments of an 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.

[0028] Figure 2 It 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 stabilization module 5. The above outer ring 2 includes an inner ring 21, an outer ring 22, and rollers 23.

[0029] Figure 3 It is a schematic structural diagram 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 application module 3, a support module 4, a stabilization module 5, a connecting member 6, and a long strip connecting hole 7.

[0030] In some embodiments, the above arterial compression device may include an inner ring 1 and an outer ring 2. Among them, a pressure application module 3, a support module 4, and a stabilization module 5 may be provided inside the above inner ring 1. The above inner ring 1 may be a connecting ring that contacts the user's bleeding site. The above outer ring 2 may be a fixing ring connected to the above inner ring 1. The above pressure application module 3 may be a component for pressing and stopping bleeding at the arterial bleeding site. The above support module 4 may be a support block located on the side of the arterial bleeding site for stable support. The above stabilization module 5 may be a stabilization block located on the back of the arterial bleeding site for stable support. For example, both the above support module 4 and the above stabilization module 5 may be silicone blocks.

[0031] In some embodiments, the above pressure application module 3, the above support module 4, and the above stabilization module 5 may be distributed in a triangle. When the arterial compression device is in a worn state, the above pressure application module 3 may be located at the arterial bleeding site. The above support module 4 may be located on the side of the arterial bleeding site. The above stabilization module 5 may be located on the back of the arterial bleeding site. Thus, by three-point support, the compression of the ulnar artery and external veins can be reduced, and the risk of blood flow obstruction can be greatly reduced.

[0032] In some embodiments, the above-mentioned pressing module 3, the above-mentioned supporting module 4, and the above-mentioned stabilizing module 5 can all be slidably arranged on the inner side of the above-mentioned inner ring 1. It can be understood that the connection positions of the above-mentioned pressing module 3, the above-mentioned supporting module 4, and the above-mentioned stabilizing module 5 with the above-mentioned inner ring 1 are adjustable. The above-mentioned pressing module 3 can include a pressure sensor and a humidity sensor. Thus, according to the size of the bleeding site of the user, adjusting the positions of the above-mentioned pressing module, the above-mentioned supporting module, and the above-mentioned stabilizing module can more accurately perform hemostatic compression on the user's artery. And through the pressure sensor and the humidity sensor, the pressing pressure of the pressing module on the artery can be determined and whether there is bleeding can be determined, so as to facilitate subsequent adjustment of the artery pressing device according to the pressing pressure and the bleeding situation.

[0033] In some embodiments, the above-mentioned outer ring 2 can include an inner ring 21 and an outer ring 22. The above-mentioned inner ring 21 can be connected to the above-mentioned inner ring 1. The above-mentioned inner ring 21 can be embedded inside the above-mentioned outer ring 22. A roller 23 can be arranged between the above-mentioned outer ring 22 and the above-mentioned inner ring 21. When the above-mentioned outer ring 22 is fixed, the above-mentioned inner ring 21 can rotate with the pressing site. Thus, by designing the outer ring as a double-ring structure and the inner ring and the outer ring can rotate relative to each other, when the outer ring of the artery pressing device is braked under an external force, it does not affect the rotation of the inner ring, thereby not affecting the movement of the bleeding site of the patient and being more convenient for the user to operate.

[0034] Optionally, the above-mentioned pressing module 3 can include a hemostatic contact block. The above-mentioned hemostatic contact block can be a silicone block. Both the above-mentioned pressure sensor and the above-mentioned humidity sensor can be arranged on the above-mentioned hemostatic contact block. As an example, the above-mentioned pressure sensor and the above-mentioned humidity sensor can be respectively bonded to both ends of the surface of the above-mentioned hemostatic contact block in contact with the bleeding site.

[0035] In the process of adopting technical solutions to solve the above technical problems, there is often the following technical problem 2: At different time periods of arterial hemostatic compression, the arterial bleeding conditions are different, so different pressing pressures are required. Using the same pressing pressure for a long time will result in poor hemostatic effect and poor user experience. In response to the above technical problem 2, the conventional solution is generally: The nurse manually adjusts the pressing pressure of the pressing module to adapt to different arterial bleeding conditions. However, the above conventional solution still has the following problems: The duration of arterial hemostasis is long, the pressing pressure of the pressing module needs to be adjusted multiple times, and manual adjustment is cumbersome, resulting in poor user experience.

[0036] Considering the problems of the above conventional solution, in the face of the above technical problem 2: At different time periods of arterial hemostatic compression, the arterial bleeding conditions are different, so different pressing pressures are required. Using the same pressing pressure for a long time will result in poor hemostatic effect and poor user experience. Combining the technical status quo, the following solution can be decided: Optionally, connectors 6 may be provided on the back surfaces of the above-mentioned pressure application module 3, the above-mentioned support module 4, and the above-mentioned stabilization module 5. Among them, the above-mentioned connector 6 may be a component for connecting the above-mentioned pressure application module 3, the above-mentioned support module 4, or the above-mentioned stabilization module 5 to the above-mentioned inner ring 1. Long strip connection holes 7 may be provided at positions on the above-mentioned inner ring 1 corresponding to the above-mentioned pressure application module 3, the above-mentioned support module 4, and the above-mentioned stabilization module 5. The length of the long strip connection hole 7 may be the movable length of the above-mentioned pressure application module 3, the above-mentioned support module 4, and the above-mentioned stabilization module 5. The specific length of the above-mentioned long strip connection hole 7 is not limited here. As an example, the length of the above-mentioned long strip connection hole 7 may be 2 cm. When the above-mentioned pressure application module 3, the above-mentioned support module 4, and the above-mentioned stabilization module 5 are connected to the inner side of the above-mentioned inner ring 1, each connector 6 may be movably connected to the long strip connection hole 7 corresponding to the above-mentioned connector 6. Specifically, when the above-mentioned connector 6 moves in the above-mentioned long strip connection hole 7, the above-mentioned pressure application module 3, the above-mentioned support module 4, or the above-mentioned stabilization module 5 connected by the above-mentioned connector 6 moves along with the connector 6.

[0037] Optionally, the above-mentioned connector 6 may include a controller and a movement control mechanism. Among them, the above-mentioned controller may be a microcontroller for controlling the above-mentioned movement control mechanism to drive the above-mentioned pressure application module 3, the above-mentioned support module 4, or the above-mentioned stabilization module 5 to move. For example, the above-mentioned controller may be STM32. The above-mentioned movement control mechanism may be a mechanism for driving the above-mentioned pressure application module 3, the above-mentioned support module 4, or the above-mentioned stabilization module 5 to move. Among them, the above-mentioned movement control mechanism may include a lead screw, a guide rail slider, and a micro motor. The motor output shaft of the above-mentioned micro motor may be connected to one end of the above-mentioned lead screw through a coupling. The above-mentioned guide rail slider may be connected to the base of the above-mentioned pressure application module 3, the above-mentioned support module 4, or the above-mentioned stabilization module 5 through bolts. When the above-mentioned micro motor is started, the above-mentioned lead screw rotates to drive the nut on the above-mentioned pressure application module 3 to move along the axial direction of the lead screw. Thus, through the above-mentioned controller and the above-mentioned movement control mechanism, the above-mentioned pressure application module 3, the above-mentioned support module 4, or the above-mentioned stabilization module 5 can be automatically controlled to move to adjust the pressure of the above-mentioned pressure application module 3, the above-mentioned support module 4, or the above-mentioned stabilization module 5 on the pressing part.

[0038] Optionally, the above-mentioned controller may be communicatively connected to the above-mentioned pressure sensor and the above-mentioned humidity sensor. The above-mentioned controller may also be configured to perform the following steps: The first step is to obtain the current humidity information collected by the above-mentioned humidity sensor. Among them, the above-mentioned humidity information may be information characterizing the bleeding condition at the current arterial bleeding site.

[0039] In the second step, determine the current humidity difference by taking the difference between the current humidity information and the humidity information corresponding to the previous humidity information. Here, the previous humidity information can be the humidity information obtained at the adjacent detection time point before the previous humidity information.

[0040] In the third step, obtain the historical humidity difference sequence corresponding to the current humidity information. Here, the historical humidity differences in the historical humidity difference sequence can be the humidity differences corresponding to the humidity information at two adjacent detection time points detected within a period of time. In practice, the historical humidity difference sequence can be obtained in the following way: First, obtain the humidity information sequence collected by the humidity sensor. Here, the humidity information sequence can include at least one humidity information. Each humidity information corresponds to a different time point. The humidity information sequence can be a set of information characterizing the bleeding condition at the arterial bleeding site detected within a previous period of time. Then, determine the difference between every two adjacent humidity information in the humidity information sequence as the historical humidity difference sequence.

[0041] In the fourth step, determine the mean value of the respective historical humidity differences in the historical humidity difference sequence as the historical humidity mean difference.

[0042] In the fifth step, determine the absolute value of the difference between the current humidity difference and the historical humidity mean difference as the current humidity change value.

[0043] In the sixth step, determine whether the current humidity change value is greater than or equal to a preset humidity change threshold. Here, the preset humidity change threshold can be a threshold at which a current humidity change value greater than this value indicates abnormal arterial bleeding.

[0044] In the seventh step, 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.

[0045] Step 8: Generate pressure adjustment information to be adjusted based on the above pressure information and the above current humidity information. Among them, the above pressure adjustment information to be adjusted can be information characterizing the pressure that the pressure application device needs to adjust. In practice, the above controller can input the above pressure information and the above humidity information into a pre-trained pressure adjustment information generation model to obtain the pressure adjustment information to be adjusted. Among them, the above pressure adjustment information generation model can be a machine learning model that takes pre-trained pressure information and current humidity information as inputs and pressure adjustment information to be adjusted as outputs. For example, the above pressure adjustment information generation model can be a random forest model. The above 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. Among them, the above input layer can be used to extract features from the pressure information and the current humidity information to obtain pressure feature information and humidity feature information. The above feature fusion layer can fuse the pressure feature information and the humidity feature information through a cross-modal attention mechanism to obtain feature fusion information. The above decision layer can be used to classify and output according to the input feature fusion information to obtain pressurization information, depressurization information, or hold information. The above safety constraint layer can be used to constrain the obtained pressurization information, depressurization information, or hold information through a clamping function to obtain the pressure adjustment information to be adjusted. The above output layer is used to output the information to be adjusted. The above pressure adjustment information generation model can be trained on the initial model through historical pressure information and historical current humidity information, and it is determined whether the training is completed through a loss function.

[0046] Step 9: Control each movement control mechanism to perform a movement operation corresponding to the above pressure adjustment information to be adjusted. In practice, the above controller can screen out the movement path information corresponding to the above pressure adjustment information to be adjusted from a preset movement path information configuration table. Among them, the above movement path information configuration table can be a configuration table characterizing the correspondence between pressure adjustment information to be adjusted and movement path information. As an example, when the above pressure adjustment information to be adjusted is +2 mmHg, the above movement path information can be to move downward by 2 mm. The above movement path information can be information including the paths that each movement control mechanism needs to move. Then, the above controller can control each movement control mechanism to move according to the above movement path information respectively.

[0047] The above - mentioned content about controlling each mobile control mechanism to perform a moving operation according to humidity information and pressure information is an inventive point of an embodiment of the present disclosure, which solves Technical Problem 2: "During different time periods of arterial compression hemostasis, the arterial bleeding conditions are different, so different compression pressures are required. Using the same compression pressure for a long time will result in poor hemostasis effect and poor user experience." The reasons for the poor hemostasis effect and poor user experience are as follows: During different time periods of arterial compression hemostasis, the arterial bleeding conditions are different, so different compression pressures are required. Using the same compression pressure for a long time will result in poor hemostasis effect and poor user experience. If the above - mentioned factors are solved, the hemostasis effect and user experience can be improved. To achieve this effect, connectors are provided on the back surfaces of the above - mentioned pressing module, the above - mentioned supporting module, and the above - mentioned stabilizing module included in the arterial compression device of the present disclosure; long - strip connection holes are provided at positions corresponding to the above - mentioned pressing module, the above - mentioned supporting module, and the above - mentioned stabilizing module on the above - mentioned inner ring, and the length of the long - strip connection holes is the movable length of the above - mentioned pressing module, the above - mentioned supporting module, and the above - mentioned stabilizing module; when the above - mentioned pressing module, the above - mentioned supporting module, and the above - mentioned stabilizing module are connected to the inner side of the above - mentioned inner ring, each connector is movably connected to the long - strip connection hole corresponding to the connector. The above - mentioned connector includes a controller and a mobile control mechanism. Among them, the above - mentioned mobile control mechanism includes a lead screw, a guide rail slider, and a micro - motor. The motor output shaft of the above - mentioned micro - motor is connected to one end of the above - mentioned lead screw through a coupling. The above - mentioned guide rail slider is connected to the base of the above - mentioned pressing module, the above - mentioned supporting module, or the above - mentioned stabilizing module through a bolt. When the above - mentioned micro - motor is started, the above - mentioned lead screw rotates to drive the nut on the above - mentioned pressing module to move along the axial direction of the lead screw. The above - mentioned controller is communicatively connected to the above - mentioned pressure sensor and the above - mentioned humidity sensor. The above - mentioned controller is further configured to perform the following steps: Obtain the current humidity information collected by the above - mentioned humidity sensor. Determine the humidity difference between the above - mentioned current humidity information and the humidity information corresponding to the previous humidity information as the current humidity difference. Obtain the historical humidity difference sequence corresponding to the above - mentioned current humidity information, where the historical humidity differences in the above - mentioned historical humidity difference sequence can be the humidity differences corresponding to the humidity information of every two adjacent detection times detected within a period of time. Determine the mean value of each historical humidity difference in the above - mentioned historical humidity difference sequence as the historical humidity mean difference. Determine the absolute value of the difference between the above - mentioned current humidity difference and the above - mentioned historical humidity mean difference as the current humidity change value. Determine whether the above - mentioned current humidity change value is greater than or equal to a preset humidity change threshold. In response to determining that the above - mentioned current humidity change value is greater than or equal to the preset humidity change threshold, obtain the pressure information detected by the above - mentioned pressure sensor. Generate pressure adjustment - pending information according to the above - mentioned pressure information and the above - mentioned current humidity information. Control each mobile control mechanism to perform a moving operation corresponding to the above - mentioned pressure adjustment - pending information according to the above - mentioned pressure adjustment - pending information.Thus, through the above-mentioned controller and the above-mentioned movement control mechanism, the above-mentioned pressing module, the above-mentioned supporting module or the above-mentioned stabilizing module can be automatically controlled to move to adjust the pressure of the above-mentioned pressing module, the above-mentioned supporting module or the above-mentioned stabilizing module on the pressing site. And the above-mentioned controller can obtain the pressure information detected by the above-mentioned pressure sensor and the humidity information detected by the above-mentioned humidity sensor, and determine the bleeding condition of the artery site according to the obtained pressure information and humidity information, so as to control the movement control mechanism to move the above-mentioned pressing module, the above-mentioned supporting module or the above-mentioned stabilizing module so that the pressing pressure is more in line with the user's usage situation, thereby improving the hemostasis effect and the user experience.

[0048] In the process of adopting technical solutions to solve the above-mentioned technical problems, there is often the following technical problem three: The patient's own conditions such as age, weight, blood vessel condition, blood pressure level, etc. have a certain impact on the patient's arterial bleeding condition. Therefore, patients with different physical conditions require different pressing pressures. For some patients with special physical conditions, using a unified pressing pressure may result in a poor hemostasis effect, thereby resulting in a poor user experience. In response to the above-mentioned technical problem three, the conventional solution is generally: The nurse observes the specific situation of the patient and manually adjusts the pressing pressure to adapt to the patient's physical condition. However, the above-mentioned conventional solution still has the following problems: For patients with poor physical conditions, it is necessary to observe the patient's physical changes at any time during the hemostasis process to adjust the pressing pressure in a timely manner. Nurses usually cannot accompany the patient at all times to observe various physical data and adjust the pressing pressure in a timely manner, resulting in a poor user experience.

[0049] Considering the problems of the above-mentioned conventional solution, in the face of the above-mentioned technical problem three: The patient's own conditions such as age, weight, blood vessel condition, blood pressure level, etc. have a certain impact on the patient's arterial bleeding condition. Therefore, patients with different physical conditions require different pressing pressures. For some patients with special physical conditions, using a unified pressing pressure may result in a poor hemostasis effect, thereby resulting in a poor user experience. Combining the technical status quo, the following solution can be decided: Optionally, the above-mentioned arterial pressing device further includes a communication module and a triaxial sensor. Among them, the above-mentioned communication module can be WiFi. The above-mentioned triaxial sensor can be a triaxial accelerometer or a triaxial gyroscope. The above-mentioned controller can be communicatively connected to the above-mentioned communication module, the above-mentioned triaxial sensor, the above-mentioned pressure sensor and the above-mentioned humidity sensor. The above-mentioned controller can also be configured to perform the following steps: In the first step, receive the patient information and the hemostasis scenario information sent by the associated intelligent device. Among them, the above-mentioned patient information can include at least one of the following: age, weight, blood pressure and vascular medical history information. The above-mentioned hemostasis scenario information can be a postoperative hemostasis scenario, an emergency hemostasis scenario or a long-term wearing hemostasis scenario.

[0064] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: The arterial compression device according to some embodiments of the present disclosure can improve the safety of user use. Specifically, the reason for the inaccurate segmentation results of the relevant segmentation model is that when using elastic nursing gauze to wrap for compression bandaging, the pressing pressure cannot be determined. When the pressure is insufficient, arterial bleeding may continue; when the pressure is too high, hematoma formation at the puncture site, peripheral nerve injury, pressure sores, etc. may occur, and limb numbness and pain may also appear; moreover, wrapping the entire site also affects blood return. Based on this, the arterial compression device according to some embodiments of the present disclosure includes an inner ring and an outer ring. Among them, a pressing module, a supporting module, and a stabilizing module are arranged inside the inner ring; the pressing module, the supporting module, and the stabilizing module are distributed in a triangle. When the arterial compression device is in a worn state, the pressing module is located at the arterial bleeding site, the supporting module is located on the side of the arterial bleeding site, and the stabilizing module is located on the back of the arterial bleeding site; the pressing module, the supporting module, and the stabilizing module are all slidably arranged on the inner side of the inner ring; the pressing module includes a pressure sensor and a humidity sensor; the outer ring includes an inner circle and an outer circle, the inner circle is connected to the inner ring, the inner circle is embedded inside the outer circle, and rollers are arranged between the outer circle and the inner circle. When the outer circle is fixed, the inner circle rotates with the pressing site. Thus, by using the pressing module, the supporting module, and the stabilizing module distributed in a triangle to support the bleeding site of the user, wrapping of the entire site can be avoided, thereby reducing the impact on blood return. And through the pressure sensor, the pressing pressure of the pressing module on the artery can be detected, so that an appropriate pressure can be used to press the artery, while ensuring the hemostasis of the artery, reducing the probability of hematoma formation at the puncture site, peripheral nerve injury, pressure sores, and limb numbness and pain. Therefore, the arterial compression device according to some embodiments of the present disclosure can improve the safety of user use.
