Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and in particular to a wound compression device after cardiovascular intervention surgery. Background Art

[0002] After cardiovascular interventional procedures, effective compression and hemostasis at the puncture site are crucial for preventing complications such as hematomas, pseudoaneurysms, and even life-threatening hemorrhage. Traditional compression methods, often relying on sandbags, bandages, or manual pressure, have numerous limitations. Sandbag pressure often produces uneven pressure, is easily misaligned, and lacks precise adjustment, increasing the risk of tissue damage beneath the punctured vessel. The heavy sandbags also cause significant discomfort and movement restrictions for patients. Manual pressure, which relies on the physical strength and experience of medical staff, results in large pressure fluctuations and is difficult to maintain. This is particularly true in the early postoperative period when patients are restricted in their movements or require prolonged compression and observation. While some existing mechanical compression devices can provide relatively stable pressure, they often suffer from issues such as inaccurate pressure regulation, a lack of visual feedback on pressure levels, and cumbersome or loose binding methods, compromising ease of use and reliability. Furthermore, prolonged use of the compression device can cause local discomfort and even vasoconstriction when the cold instrument contacts the skin, hindering local circulation recovery.

[0003] Therefore, in order to solve the above problems, a post-operative wound compression device for cardiovascular intervention is now developed. Summary of the Invention

Two symmetrical limit plates 10 are installed on the soft frame 2. A pressure plate 11 is slidably connected between the limit plates 10. A driving motor 12 is installed on the right side of the installation frame 1. A bidirectional screw rod 13 is connected to the output shaft of the driving motor 12. The bidirectional screw rod 13 is rotatably connected to the installation frame 1. A movable frame 14 is provided on both sides of the pressure plate 11. The movable frame 14 is slidably connected to the limit plate 10. The movable frame 14 is threadedly connected to the bidirectional screw rod 13. The middle position of the installation frame 1 is threadedly connected. There is a threaded pressing piece 15, a power-assisted screwing hand is provided on the top of the threaded pressing piece 15, and the bottom of the threaded pressing piece 15 is a spherical structure. Fixed plates 17 are provided on both sides of the mounting frame 1. A sliding plate 16 is slidably connected between the fixed plates 17. Two springs 18 are connected between the sliding plate 16 and the fixed plate 17. The sliding plate 16 is squeezed by the threaded pressing piece 15, thereby acting on the pressure plate 11. A rack 19 is installed on the upper right side of the sliding plate 16. A mounting frame 20 is provided on the top of the mounting frame 1. A gear 21 is rotatably connected to the mounting frame 20. The gear 21 is connected to the rack 19. Engagement, a marking plate 22 is rotatably connected to the mounting frame 20, and the marking plate 22 is used to indicate the degree of downward pressure of the sliding plate 16. A synchronization component 23 is connected between the marking plate 22 and the gear 21, and the synchronization component 23 is composed of a pulley and a belt, wherein the pulleys are respectively installed on the rear side of the gear 21 and the marking plate 22, and the belt is wound between the pulleys. A heating component 24 is provided in the mounting frame 1, and the heating component 24 can increase the temperature of the soft frame 2 when it contacts the patient's skin. A clamping member 25 is provided on the right side of the mounting frame 1, and the clamping member 25 is used to limit the drive motor 12.

[0028] It should be noted that the medical staff first gently places the soft frame 2 with a soft pressure-applying body on the skin wound at the patient's surgical puncture site, and uses the adjustable connecting belts 4 arranged on both sides of the installation frame 1 to tie and fix the patient's limb. The special Velcro component 6 on the connecting belt 4 is used to guide and initially engage and lock the end of the connecting belt 4 after the loop to form a preliminary fixing circle. Then, in order to obtain a lasting and precisely adjustable fixing force, the operator pushes the sliding member 9 on the left and right sides of the rotating member 5, driving the second clamping member 7 thereon to slide toward the connecting belt, and uses the elastic member 8 designed on the second clamping member 7 to firmly engage and lock the connecting belt 4 for the second time, ensuring that the device body is firmly and stably bound to the affected limb to avoid If the device accidentally becomes loose due to limb movement or the passage of time, the control component 3 at the core of the device is activated, and the system begins the intelligent pressure application process: the drive motor 12 placed on the right side of the installation frame 1 operates according to the preset program or the program set by the medical staff, and its output shaft drives the bidirectional screw 13 connected to it to rotate precisely in the installation frame 1. Since the two ends of the bidirectional screw 13 have threads, the movable frame 14 threadedly connected to it on the left and right sides respectively will slide along the inner side of the two parallel limit plates 10 fixed to the front and rear sides of the soft frame 2 under the rotation drive of the screw, so that the pressure plate 11 can be accurately adjusted under the track constraint of the limit plate 10, thereby applying a controllable and uniform main pressure to the surgical wound and surrounding tissues covered by the soft frame 2 below. This is driven by the motor. The driven mechanical downward pressure constitutes the first core pressure layer of the entire compression system. In order to achieve more precise and flexible personalized fine-tuning of the wound pressure and provide elastic buffering that conforms to the human body's comfortable curve, a threaded pressing piece 15 is also designed in the middle of the device. Medical staff rotate the special power-assisted screw handle on the top of the threaded pressing piece 15 to enable the threaded pressing piece 15 to achieve precise displacement of screwing in or out along the preset threaded hole in the middle of the installation frame 1, and the carefully designed spherical structure at the bottom thereof moves downward or upward accordingly. When the threaded pressing piece 15 is screwed in, its spherical end first contacts and presses downward the middle area of ​​the sliding plate 16 set between the left and right fixed plates 17 inside the installation frame 1. Since the sliding plate 16 and the fixed plates 17 on both sides are connected by at least two pre-compressed springs 18 ( The sliding plate 16 is connected to the spring 18 to form a precise elastic pressure plate 11 system. When the sliding plate 16 is pushed down to overcome the resistance of the spring 18, its leading edge or specific contact point (in direct contact with the pressure plate 11) drives the pressure plate 11 downward, forcing the pressure plate 11 to add an additional subtle, infinitely adjustable superimposed pressure component on the basis of the macro displacement of the sliding of the movable frame 14. This pressure is not only softer but also elastic, and can adapt to the slight swelling changes of the patient's limbs over time and provide dynamic relief, forming a second fine elastic pressure layer above the main mechanical pressure. When the sliding plate 16 is displaced up and down by the threaded pressing piece 15, the rack 19 installed on the upper right side of the sliding plate 16 moves synchronously.The rack 19 drives the gear 21 meshing with it and mounted on the internal mounting frame 20 at the top of the mounting frame 1 to rotate. The rotation of the gear 21 is transmitted to the marking plate 22 also mounted on the mounting frame 20 through a set of efficient synchronization components 23. The displacement of the sliding plate 16 is fed back to the medical staff in real time and visually through the changes in the scale or pattern clearly marked on the marking plate 22, thereby indicating the degree of overall compression force applied and ensuring that the pressure is within a safe and effective range. In addition, in order to enhance the patient experience and possibly improve local blood circulation to reduce complications, the device is integrated with a heating component 24, which is placed in the mounting frame 1 and can transfer the appropriately increased temperature to the surface of the soft frame 2 in contact with the patient's skin through a conduction mechanism, so that the compressed area feels gentle warmth. To ensure the position stability and operational reliability of the drive motor 12 during operation, A clamping member 25 is also provided on the right side of the mounting frame 1 to firmly limit the position of the motor, absorb minor vibrations during operation, and ensure the stability and durability of the bidirectional screw 13 transmission system. In summary, the device coordinates the automatic main pressure of the drive motor 12 and the manual fine elastic pressure of the threaded pressure member 15 through the intelligent control component 3. The dual-level coupling mechanism effectively and collaboratively achieves precise, continuous, and adjustable wound compression. At the same time, combined with visual pressure indication, gentle heating, and multiple card lock belt designs, it provides patients with a safe, reliable, comfortable, and easy-to-operate complete compression solution for wound hemostasis and healing. When the device needs to be removed after the compression is completed several hours after the operation, the operator can first release the lock on the connecting belt by the second clamping member 7 controlled by the elastic member 8, and then undo the initial engagement of the Velcro component 6 to conveniently and painlessly loosen and remove the device.
