Abstract
Description
Technical Field
[0001] This invention relates to the field of postoperative care equipment for cardiovascular interventional procedures, specifically to an intelligent hemostasis and monitoring robot for puncture sites after cardiovascular interventional procedures. Background Technology
[0002] Cardiovascular interventional procedures, as a core minimally invasive technique for treating cardiovascular diseases such as coronary heart disease and arrhythmias, have been widely used in clinical practice due to their advantages of minimal trauma, rapid recovery, and definite efficacy. However, hemostasis at the puncture site remains a critical aspect of clinical nursing care. If hemostasis is not timely or pressure is not properly controlled at the puncture site, complications such as bleeding, hematoma, and pseudoaneurysm can easily occur, not only prolonging hospital stays and increasing medical costs, but also potentially endangering the patient's life in severe cases. Therefore, effective hemostasis and real-time monitoring of the puncture site are directly related to the safety of cardiovascular interventional procedures and patient prognosis, becoming a significant technical challenge that urgently needs optimization in clinical practice. Currently, commonly used methods for hemostasis at puncture sites in clinical practice mainly include manual pressure hemostasis, mechanical tourniquet hemostasis, and traditional compression devices. Manual pressure relies on the experience of medical staff, and it is difficult to maintain a constant pressure. Prolonged pressure can easily lead to fatigue of medical staff, and continuous monitoring is not possible. Insufficient or excessive pressure can easily cause complications. Although mechanical tourniquets can provide stable pressure, their adjustment flexibility is poor. They cannot dynamically adjust the pressure according to the patient's bleeding situation, and they lack visual monitoring of the puncture site. Medical staff need to repeatedly disassemble and inspect the device, increasing the risk of infection. Traditional compression devices are mostly passive compression structures, which are difficult to deal with sudden situations such as limb movement or sudden rise in blood pressure. Their emergency protection capabilities are insufficient and cannot meet the clinical needs for precise and intelligent hemostasis. As medical technology advances towards precision and intelligence, the clinical requirements for puncture site hemostasis devices are increasing. These devices not only need to achieve stable and controllable pressure hemostasis but also require integrated capabilities such as real-time monitoring, dynamic pressure adjustment, and emergency response. Existing hemostasis methods, with their shortcomings in pressure stability, monitoring accuracy, and intelligent adjustment, are no longer adequate for the clinical needs of modern cardiovascular interventional procedures. Therefore, developing an intelligent hemostasis and monitoring device capable of precisely controlling pressure, monitoring the puncture site status in real time, dynamically adjusting hemostasis strategies, and responding to sudden risks is of great significance for improving the quality of post-cardiovascular interventional care, reducing the incidence of complications, and alleviating the workload of medical staff, thus becoming a key direction for technological research and development in this field.

[0016] This invention provides an intelligent hemostasis and monitoring robot for puncture sites after cardiovascular interventional procedures. It offers the following advantages: 1. This invention achieves hemostasis by transmitting the elastic force of a spring sheet. At the same time, it utilizes the relative sliding between the pressure roller and the spring sheet to dynamically compensate for the change in elastic force during the bending process of the spring sheet, so that the pressure of the flexible pressure pad on the puncture point remains constant, avoiding problems such as hemostasis failure due to pressure fluctuations or skin damage and obstruction of blood circulation caused by excessive pressure.
[0017] 2. This invention relies on the intelligent decompression strategy of "the higher the degree of vascular closure, the greater the decompression range". After the hemostasis status at the puncture point is achieved, automatic gradient decompression is performed. This avoids the compression damage to local tissues caused by continuous high pressure, and also prevents secondary bleeding caused by excessive decompression, thus achieving a balance between hemostasis and tissue protection.
[0018] 3. When a patient experiences a sudden increase in blood pressure, cough, or sudden change in heart rate, the device uses an emergency pressurization mechanism composed of components such as an electromagnetic ring, a magnetic moving block, and a valve needle to quickly connect the upper and lower spaces of the inner cylinder. The pressure difference of high-pressure nitrogen gas pushes the transparent pressure block to press down instantaneously and continuously, achieving millisecond-level emergency pressurization. This promptly curbs bleeding at the puncture site caused by sudden pressure changes, significantly reducing the probability of postoperative bleeding complications and providing dual protection for patient safety.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example:
[0022] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides an intelligent hemostasis and monitoring robot for puncture sites after cardiovascular interventional procedures, such as... Figure 1As shown, the device includes a housing 1, which serves as the mounting base and external protective structure for the entire device. It provides a stable mounting space for the internal functional components and protects the internal precision parts from external interference and damage. A fixed pressure frame 2 is movably installed at the bottom of the housing 1. The fixed pressure frame 2 serves as the mounting carrier for the flexible pressure pad 3, transmitting the pressure from the upper mechanism and driving the flexible pressure pad 3 to move up and down, thereby accurately applying pressure to the puncture point. The flexible pressure pad 3 is fixedly installed at the bottom of the fixed pressure frame 2. The flexible pressure pad 3 is made of flexible material, which can fit closely to the patient's skin, reducing discomfort during the pressing process and avoiding damage to the skin due to rigid contact. A glass pressure plate 4 is fixedly installed in the middle of the flexible pressure pad 3. The glass pressure plate 4 has good light transmittance, which does not affect the monitoring of the puncture point by the monitoring camera 29, and provides stable pressure support for the puncture point to ensure hemostasis. In this embodiment, a fixed frame 5 is provided in the middle of the inner part of the housing 1. The fixed frame 5 is the core structure connecting the telescopic cylinder 11 with the rotating frame 6, spring plate 8 and other components. It can transmit the driving force of the telescopic cylinder 11 to the fixed pressure frame 2 below, and at the same time provide the installation base for the internal cavities such as the first chamber 7 and the second chamber 12. The rotating frame 6 is movably installed at both ends of the fixed frame 5. The rotating frame 6 can rotate around the end of the fixed frame 5. Through the connecting rod 10, its bending action is converted into the up and down movement of the fixed pressure frame 2 to realize the transmission of pressure. The first chamber 7 is opened on both sides of the inner part of the fixed frame 5. The first chamber 7 provides a closed installation space for components such as spring plate 8, support platform 17, and threaded rod 16 to prevent external dust or impurities from entering and affecting the operation of the components. Spring plates 8 are fixedly installed on both sides of the inner part of the first chamber 7, and the ends of the spring plates 8 extend to the corresponding rotating sides. Inside the rotating frame 6, the spring plate 8 has good elastic deformation capability. When the rotating frame 6 applies pressure through the pressure roller 9, it bends and generates a reverse elastic force that acts on the fixed pressure frame 2, providing continuous and stable pressure for pressing the puncture point. One end of the inner wall of the rotating frame 6 is fixedly installed with a pressure roller 9, and the end of the pressure roller 9 abuts against the lower surface of the corresponding spring plate 8. During the bending process of the rotating frame 6, the pressure roller 9 slides relative to the surface of the spring plate 8. By adjusting the force point of the spring plate 8 through sliding, the elastic force fluctuation caused by the change in the degree of bending of the spring plate 8 is compensated, ensuring that the pressing pressure is always stable. The bottom end of the rotating frame 6 is movably installed with a connecting rod 10, and the ends of the connecting rod 10 are respectively installed on both sides of the top of the fixed pressure frame 2. The connecting rod 10 serves to connect the rotating frame 6 and the fixed pressure frame 2, accurately transmitting the mechanical movement of the rotating frame 6 to the fixed pressure frame 2, realizing the power linkage between the two. Furthermore, a cylindrical groove 19 is provided in the middle of the fixed pressure frame 2. The cylindrical groove 19 provides installation space for components such as the outer cylinder 20 and the supplementary light bulb 38, and at the same time creates a stable monitoring environment for the monitoring camera 29. The outer cylinder 20 is movably installed inside the cylindrical groove 19. The outer cylinder 20 can move up and down within the cylindrical groove 19. The transparent pressure block 28 at its bottom end can quickly move down during emergency pressurization to apply secondary pressure to the puncture point. The outer cylinder 20 has a middle cylinder 21 inside, and the top two sides of the middle cylinder 21 are connected to the upper surface of the fixed pressure frame 2 by fixing rods. The middle cylinder 21 is an inner cylinder 24, an electromagnetic ring 30, and a magnetic active... The moving block 31 and other components provide a fixed installation base and form a cavity 37 with the inner cylinder 24 for air pressure transmission. Upper positioning blocks 22 and lower positioning blocks 23 are fixedly installed on the upper and lower sides of the inner cylinder 21, respectively. These blocks fix the two ends of the inner cylinder 24, ensuring its stability within the inner cylinder 21. Upper ventilation slots 35 and lower ventilation slots 36 are also provided to allow airflow communication between the cavity 37 and the inner cylinder 24. The inner ends of the upper positioning blocks 22 and lower positioning blocks 23 are fixedly installed at both ends of the inner cylinder 24, which is filled with high-pressure nitrogen. To provide power for emergency pressurization, the pressure difference of nitrogen gas drives the rubber piston 27. A crossbeam 25 is fixedly installed on the lower inner side of the outer cylinder 20, providing stable support for the piston rod 26 and ensuring that the piston rod 26 can move up and down in a straight line. The piston rod 26 is fixedly installed in the middle of the crossbeam 25, connecting the rubber piston 27 and the crossbeam 25, transmitting the movement of the rubber piston 27 to the outer cylinder 20, thus driving the outer cylinder 20 to achieve emergency pressurization. The top of the piston rod 26 extends into the inner cylinder 24 and is fixedly installed with the rubber piston 27, which divides the inner cylinder 24 into sections. The upper and lower independent spaces are powered by the pressure difference to push the piston rod 26 downward, providing power for emergency pressurization. A transparent pressure block 28 is fixedly installed at the bottom of the outer cylinder 20. The transparent pressure block 28 has good light transmittance and does not affect the monitoring function of the monitoring camera 29. At the same time, it directly contacts the glass pressure plate 4 during emergency pressurization, providing additional pressure to the puncture point. A monitoring camera 29 is fixedly installed at the bottom of the inner side of the outer cylinder 20. The monitoring camera 29 is used to capture information such as the bleeding status and skin condition of the puncture point in real time, and feeds the monitoring image back to the monitoring screen 40, providing medical staff and patients with intuitive reference for the progress of hemostasis. Furthermore, a telescopic cylinder 11 is fixedly installed at the top center of the housing 1, and the driving end of the telescopic cylinder 11 extends into the interior of the housing 1 and is fixedly installed at the top of the fixed frame 5. The telescopic cylinder 11 serves as one of the power sources of the device. Through telescopic movement, it pushes the fixed frame 5 to move up and down, providing initial driving force for the pressing action of the fixed pressure frame 2, and realizing the initial application of blood pressure-stopping force. Furthermore, a second chamber 12 is provided in the center of the fixed frame 5. The second chamber 12 provides installation space for transmission components such as the geared motor 13, the driving bevel gear 14, and the driven bevel gear 18, ensuring the stability and sealing of the gear transmission. The geared motor 13 is fixedly installed at the center of the top of the fixed frame 5. The geared motor 13 provides power for pressure regulation and achieves precise rotation of the threaded rod 16 by controlling the rotation speed, thereby adjusting the position of the support platform 17. The drive end of the geared motor 13 extends into the interior of the second chamber 12 and is fixedly installed with the driving bevel gear 14. The driving bevel gear 14 rotates under the drive of the geared motor 13, transmitting power to both sides. Driven bevel gear 18 enables power distribution. Short shafts 15 are movably installed in the middle of the inner wall of the first chamber 7. The short shafts 15 are used to connect the driven bevel gear 18 and the threaded rod 16, transmitting the rotational motion of the driven bevel gear 18 to the threaded rod 16. The inner ends of the short shafts 15 extend into the interior of the second chamber 12 and are fixedly installed with driven bevel gears 18. The driven bevel gears 18 are meshed with the driving bevel gear 14, receiving the power transmitted by the driving bevel gear 14 and driving the short shafts 15 to rotate. The inner ends of the driven bevel gears 18 are respectively meshed with both sides of the driving bevel gear 14. Through the symmetrically arranged driven bevel gears 18 on both sides, the threaded rods 16 on both sides are ensured to rotate synchronously, realizing the symmetrical movement of the support platform 17. Furthermore, each of the first chambers 7 has a movably installed support platform 17, with both sides of the support platform 17 abutting against the upper surface of the corresponding spring plate 8. The support platform 17 can adjust the support position of the spring plate 8 by moving left and right, thereby changing the elastic force of the spring plate 8 and adjusting the pressing pressure. Each of the outer ends of the short shaft 15 has a threaded rod 16 fixedly installed, and the outer diameter of the threaded rod 16 is threaded to the middle of the corresponding support platform 17. The rotational motion of the threaded rod 16 is converted into the linear motion of the support platform 17. The precision of the threaded transmission ensures the accuracy of the position adjustment of the support platform 17, thereby achieving precise pressure adjustment. Furthermore, a cavity 37 is provided between the outer wall of the inner cylinder 24 and the inner wall of the middle cylinder 21. The cavity 37 serves as an airflow channel, connecting the upper venting groove 35 and the lower venting groove 36, thereby enabling airflow communication between the upper and lower spaces of the inner cylinder 24 and ensuring air pressure balance during emergency pressurization. Furthermore, an electromagnetic ring 30 is fixedly installed on the upper side of the inner cylinder 21. When the electromagnetic ring 30 is energized, it generates a magnetic force, attracting the magnetic movable block 31 to move downward, triggering the action of the emergency pressurization mechanism. The magnetic movable block 31 is movably installed inside the inner cylinder 21 near the upper part of the electromagnetic ring 30 through two return springs 32. The magnetic movable block 31 moves downward under the magnetic force of the electromagnetic ring 30, driving the valve needle 34 to move. After the emergency pressurization ends, it returns to the initial position under the elastic force of the return spring 32, realizing the reset of the mechanism. Furthermore, a through groove 33 is provided in the middle of the upper positioning block 22. The through groove 33 provides a moving channel for the valve needle 34, ensuring that the valve needle 34 can move up and down smoothly and realize the opening and closing control of the ventilation channel. The valve needle 34 is fixedly installed in the middle of the bottom end of the magnetic movable block 31, and the end of the valve needle 34 penetrates the interior of the through groove 33. The valve needle 34 moves down under the drive of the magnetic movable block 31, opening the communication channel between the upper ventilation groove 35 and the upper space of the inner cylinder 24, realizing the airflow communication between the upper and lower spaces of the inner cylinder 24. Furthermore, an upper venting groove 35 is provided on one side of the upper positioning block 22, and the two ends of the upper venting groove 35 are respectively connected to the cavity 37 and the upper side of the inner cylinder 24. The upper venting groove 35 serves as an airflow channel, connecting the upper space of the inner cylinder 24 with the cavity 37. A lower venting groove 36 is provided on one side of the lower positioning block 23, and the two ends of the lower venting groove 36 are respectively connected to the cavity 37 and the lower side of the inner cylinder 24. The lower venting groove 36 connects the lower space of the inner cylinder 24 with the cavity 37. Through the cooperation of the upper venting groove 35 and the lower venting groove 36, airflow circulation between the upper and lower spaces of the inner cylinder 24 is achieved. The inner cylinder 24 is filled with high-pressure nitrogen, which serves as the power medium for emergency pressurization. The force generated by the pressure difference pushes the rubber piston 27 downward, providing sufficient power for emergency pressurization. Furthermore, several supplementary light beads 38 are fixedly installed on the lower inner wall of the cylindrical groove 19. The supplementary light beads 38 provide sufficient illumination when the monitoring camera 29 is working, eliminating the influence of insufficient light on the monitoring image and ensuring that the monitoring camera 29 can clearly capture the details of the puncture point. Furthermore, a strap 39 is fixedly installed on one side of the bottom of the housing 1. The strap 39 is used to fix the device to the patient's limb to ensure that the device will not shift due to limb movement during hemostasis, thus ensuring the accuracy and stability of the pressure position. A monitoring screen 40 is fixedly installed at the front end of the housing 1. The monitoring screen 40 is used to receive and display the monitoring images transmitted by the monitoring camera 29, and at the same time provide feedback on the working status of the device, pressure value and other information, so that medical staff and patients can keep track of the hemostasis situation in real time.
[0023] Working principle: The device is aligned with the user's puncture site, and the glass pressure plate 4 is aligned with the user's puncture point. The device is then secured to the user's limb using the strap 39. Once completed, the telescopic cylinder 11 is activated, pushing the fixing frame 5 downwards, which in turn lowers the fixing pressure frame 2 and the flexible pressure pad 3. When the flexible pressure pad 3 contacts the skin, the telescopic cylinder 11 continues to control the descent of the fixing frame 5. At this time, the fixing pressure frame 2 bends the rotating frame 6 via the connecting rod 10. The bent rotating frame 6 bends the spring plate 8 via the pressure roller 9. The bent spring plate 8 generates elastic force that acts in the opposite direction on the fixing pressure frame 2 and the flexible pressure pad 3, applying pressure to the puncture point to stop bleeding. During this process, the supplementary light bulb 38 provides illumination, and the monitoring camera 29 monitors the bleeding status of the puncture point in real time and displays the results on the monitoring screen. On the 40, during the bending process of the spring sheet 8, the pressure roller 9 will slide relative to the surface of the spring sheet 8, causing the lever arm of the bent spring sheet 8 to change, compensating for the change in elastic force of the spring sheet 8 as the degree of bending changes, thus keeping the elastic force generated by the spring sheet 8 stable. The pressure of the flexible pressure pad 3 on the puncture point will also remain stable, so that even when the user's limb moves, the pressure will remain stable. When the monitoring camera 29 detects that there is no bleeding at the puncture point and the vascular closure reaches more than 90%, the system automatically starts decompression. At this time, the reduction motor 13 drives the active bevel gear 14 to rotate. The rotating active bevel gear 14 will drive the driven bevel gears 18 and the short shaft 15 on both sides to rotate, thereby driving the threaded rod 16 to rotate. 6. When rotating, it will drive the support platforms 17 on both sides to move inward synchronously. When the support platforms 17 move inward, the support point of the spring plate 8 will move inward, making the elastic force generated by the spring plate 8 smaller. The pressure exerted on the puncture point by the fixed pressure frame 2 and the flexible pressure pad 3 will also decrease, realizing the decompression function. The decompression range is intelligently adjusted according to the strategy of "the higher the closure degree, the greater the decompression range". When the user suddenly experiences a sudden increase in blood pressure or coughing, or a sudden change in heart rate, emergency pressurization is directly triggered. At this time, the electromagnetic ring 30 is energized to generate magnetic force, attracting the magnetic moving block 31 to descend. When the magnetic moving block 31 descends, it drives the valve needle 34 to descend. Since the rubber piston 27 divides the inner cylinder 24 into an upper space and a lower space, when the valve needle 34 moves down, it will cause the cavity 37 to pass through the upper ventilation groove 3. 5 and the through groove 33 are connected to the upper space of the inner cylinder 24, while the bottom of the cavity 37 is connected to the lower space of the inner cylinder 24 through the lower vent groove 36. Therefore, the upper and lower spaces of the inner cylinder 24 are connected at this time, and the upper and lower air pressures are the same. According to the gas pressure formula, the force exerted by the air pressure in the upper space of the inner cylinder 24 on the rubber piston 27 is the product of the pressure and the complete area of the rubber piston 27, while the force exerted by the air pressure in the lower space of the inner cylinder 24 on the rubber piston 27 is the product of the pressure and the area of the rubber piston 27 minus the cross-sectional area of the piston rod 26. Therefore, the pressure generated in the upper space is greater, which in turn pushes the rubber piston 27 downward to compress the lower space, causing high-pressure nitrogen to flow from the lower space to the upper space, thereby causing the outer cylinder 20 and the transparent pressure block 28 to descend rapidly.Until contact with the glass pressure plate 4 and continuous pressure is applied, a rapid emergency pressurization function is achieved to prevent continuous bleeding from the puncture site.
