Description

Technical Field

[0001] This invention relates to the field of puncture and swelling reduction technology, specifically to a device for reducing swelling in the puncture site area for cardiology patients. Background Technology

[0002] Hematoma and edema at the puncture site are common complications after interventional cardiovascular procedures. Traditional methods of reducing swelling, relying on manual pressure, elastic bandages, or simple pressure pads, have significant drawbacks. The pressure provided by these methods is often uncontrollable, uneven, and cannot be dynamically adjusted. Insufficient pressure may lead to ineffective swelling reduction, while excessive pressure may cause skin damage. At the same time, they lack real-time monitoring and feedback of tissue condition, are difficult to conform to the contours of the limb, resulting in poor patient comfort. Essentially, they cannot simulate the physiological swelling reduction process of gradually dispersing swelling from the center outwards.

[0003] Although air-filled compression devices have been developed, most are only single or simple combinations of airbags, with limited pressure modes and weak inter-area coordination, failing to achieve intelligent, coordinated gradient pressure. Therefore, there is an urgent clinical need for an intelligent swelling reduction device that integrates precise gradient pressure, real-time physiological feedback, dynamic adaptive adjustment, and comfortable fit. This device is designed for this purpose. Through a multi-layered annular airbag matrix, flexible bioimpedance sensing, and independent pneumatic control, it aims to achieve programmable, adjustable simulated massage of the puncture area from the center outwards, effectively promoting tissue fluid return and improving postoperative care quality and patient comfort.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Example like Figures 1-10 As shown, a device for reducing swelling at the puncture site for cardiology patients includes a fixation component 1; The top of the fixing component 1 is provided with a pressing component 2 for pressing the puncture area, and the bottom of the pressing component 2 is provided with a swelling reduction component 3 for pressing the pressing area to reduce swelling. The swelling reduction component 3 is composed of a central pressure regulating component 31 for central pressure regulation and a first pressure regulating component 32, a second pressure regulating component 33, a third pressure regulating component 34 and a fourth pressure regulating component 35 for cross pressure regulation, which are sequentially and ring-connected.

[0022] A swelling reduction device for puncture sites in cardiology patients is based on the coordinated operation of a fixation component 1, a pressing component 2, and a swelling reduction component 3. The fixation component 1 forms the base for wearing the device, and the pressing component 2 is mechanically fixed to its top. The main function of the pressing component 2 is to align with and cover the puncture area. The swelling reduction component 3 is installed at the bottom of the pressing component 2. The swelling reduction component 3 directly acts on the central pressure adjustment component 31 at the puncture point, and is composed of a first adjustment component 32, a second adjustment component 33, a third adjustment component 34, and a fourth pressure adjustment component 35, which are concentrically ringed and bolted together to apply pressure from the inside out. This allows the pressure to be applied in an adjustable, radial gradient from the puncture point to the surrounding tissue, simulating the swelling reduction principle of pushing from the center to the periphery in manual massage, effectively promoting the return and absorption of tissue fluid.

[0023] The fixing component 1 consists of two rigid tabs 11. The two rigid tabs 11 are symmetrically arranged on the top of the fixing component 1. Arc-shaped connecting pieces 12 and connecting shafts 14 are fixedly connected to the two ends of the rigid tabs 11 respectively. Velcro fasteners 15 are fitted on both connecting shafts 14. A control power module 13 is provided on the top of one of the rigid tabs 11.

[0024] The fixing component 1 consists of two rigid plates 11 with certain rigidity and strength. These two rigid plates 11 are symmetrically arranged on both sides of the device, forming a basic frame that can surround the patient's limb. Each rigid plate 11 has an arc-shaped connector 12 and a connecting shaft 14 fixedly connected to its two ends by welding. The two connecting shafts 14 are arranged in parallel and pass through the shaft hole of a Velcro clasp 15, so that the two rigid plates 11 can be opened, closed and tightened by the Velcro clasp 15, thus conveniently fixing them to the patient's arm or leg. For centralized control, a control power module 13 containing a control circuit board and power supply is fixedly installed on the top outer surface of one of the rigid plates 11 by bolts. It provides power and control signals to all subsequent pneumatic components.

[0025] The pressing assembly 2 consists of an adjusting block 21, which is fixedly connected to one side of two arc-shaped contact plates 12. The adjusting block 21 has an internal threaded block 22, and the internal threaded block 22 is connected to a transmission screw 23. The two ends of the transmission screw 23 are respectively fixedly connected to a screw head 24 and a rotating block 25. A connecting block 26 is movably sleeved on the outer circumference of the rotating block 25. The connecting block 26 has a transmission groove 27 inside, and the rotating block 25 is rotatably installed inside the transmission groove 27.

[0026] The main body of the pressing component 2 is an adjusting block 21. The adjusting block 21 is simultaneously bolted to two arc-shaped connecting pieces 12 through the brackets on both sides, thereby achieving a stable connection with the fixed component 1. The adjusting block 21 has a through hole machined inside, in which an internal threaded block 22 is installed. A transmission screw 23 is threadedly connected to the internal threaded block 22. The upper end of the transmission screw 23 is fixedly connected to a screw head 24 for manual rotation by the user, and the lower end is fixedly connected to a rotating block 25. The rotating block 25 is movably fitted in a spherical transmission groove 27 inside a connecting block 26, forming a ball joint connection. When the screw head 24 is manually rotated, the transmission screw 23 rotates. Since the internal threaded block 22 is restricted from circumferential rotation, the rotational motion of the transmission screw 23 is converted into its own linear motion along the axial direction through the threaded pair, thereby driving the lower rotating block 25 and the entire connecting block 26 to move up and down, realizing the fine adjustment of the overall pressing height of the swelling reduction component 3.

[0027] The swelling reduction component 3 also includes a connecting frame 302, which is fixedly connected to the bottom of the connecting block 26. A pressing frame 301 is fixedly connected to the bottom of the connecting frame 302, and an air inlet grille 303 is provided between the pressing frame 301 and the connecting frame 302.

[0028] A square connecting frame 302 is fixedly connected to the bottom of the connecting block 26 by bolts. Directly below the connecting frame 302, a larger clamping frame 301 is fixedly connected. A certain gap is maintained between the clamping frame 301 and the connecting frame 302. The gap is surrounded on all four sides, while a grid-like air inlet grille 303 is embedded in the central area. The connecting frame 302 and the clamping frame 301 together form a rigid mounting cavity. Each pressure regulating component of the swelling reduction component 3 is installed in the internal space of the clamping frame 301. The function of the air inlet grille 303 is to ensure that the multiple air pumps inside the mounting cavity can draw in external air for heat dissipation when working, preventing device failure or affecting service life due to overheating.

[0029] The central pressure regulating component 31 consists of a central fixing frame 310, which is slidably disposed inside the pressing frame 301. A pressing air pump 311 is installed on the top of the central fixing frame 310, and a first connecting pipe 312 is installed at the output end of the pressing air pump 311. A central airbag 313 is fixedly connected to the bottom of the central fixing frame 310, and the central airbag 313 and the pressing air pump 311 are connected together by the first connecting pipe 312.

[0030] The central pressure regulating component 31 includes a central fixing frame 310. The central fixing frame 310 is slidably positioned at the center of the pressure frame 301 by engaging with a vertical sliding groove on the inner wall of the pressure frame 301 via a guide protrusion on its side wall. A miniature pressing air pump 311 is installed on the top plate of the central fixing frame 310 by screws. The air inlet of the pressing air pump 311 is connected to the outside air through a filter screen, and its air outlet is connected to the central airbag 313, which is bonded and fixed to the bottom of the central fixing frame 310, through a flexible first connecting pipe 312. The control power module 13 drives the pressing air pump 311 to work according to the command, pumping air into the central airbag 313 to inflate it, thereby directly applying vertical downward pressure to the puncture point. When pressure reduction is required, the pressure relief valve in the air pump opens, the gas in the airbag is discharged, and the pressure decreases.

[0031] The first pressure regulating component 32 is composed of a first pressure frame 320, which is movably fitted on the outer circumferential surface of the central fixed frame 310. The top and bottom of the first pressure frame 320 are respectively fixedly connected to a first air distribution plate 323 and a first pressure airbag 325. A first air pump 321 is installed inside the pressing frame 301. The first air pump 321 and the first air distribution plate 323 are connected by a first pipe 322. The first air distribution plate 323 and the first pressure airbag 325 are connected by a plurality of circumferentially distributed first branch pipes 324.

[0032] The first pressure regulating assembly 32 includes a first pressure frame 320, which is fitted onto the outer circumferential surface of the central fixed frame 310 via an inner annular slide rail, allowing relative sliding. An annular first air distribution plate 323 is fixedly installed on the inner side of the top surface of the first pressure frame 320, and an annular first pressure airbag 325 is bonded and fixed to its bottom surface. A first air pump 321 is fixed at an independent mounting position on the inner wall of the pressing frame 301, and the first air pump 321 is connected to the main air intake pipe of the first air distribution plate 323 via a first pipe 322. Next, multiple circumferentially distributed air outlets are provided below the first air distribution plate 323. Each air outlet is connected to the corresponding independent air chamber of the first pressure airbag 325 through an independent first branch pipe 324. After the first air pump 321 is started in control, the gas is sent into the first air distribution plate 323 through the first pipe 322, and then evenly distributed to various areas of the first pressure airbag 325 through the first air distribution plate 323 through multiple first branch pipes 324, ensuring that the annular airbag is inflated evenly and generating a stable, annular, uniform pressure on the first ring of tissue around the central airbag 313.

[0033] The second pressure regulating component 33 is composed of a second pressure frame 330, which is movably fitted onto the outer circumferential surface of the first pressure frame 320. The top and bottom of the second pressure frame 330 are respectively fixedly connected to a second air distribution plate 333 and a second pressure airbag 335. A second air pump 331 is installed inside the clamping frame 301. The second air pump 331 and the second air distribution plate 333 are connected together by a second pipe 332. The second air distribution plate 333 and the second pressure airbag 335 are connected together by a number of circumferentially distributed second branch pipes 334.

[0034] The second pressure regulating component 33 is similar to but independent of the first pressure regulating component 32. It includes a second pressure frame 330, which is fitted onto the outer circumferential surface of the first pressure frame 320 via an inner slide rail. The second pressure frame 330 has a second air distribution plate 333 at its top and a second pressure airbag 335 at its bottom. A second air pump 331, independently installed inside the compression frame 301, is connected to the second air distribution plate 333 via a second pipe 332. The second air distribution plate 333 also uniformly introduces gas into the second pressure airbag 335 through multiple circumferentially distributed second branch pipes 334. It is exactly the same as the first pressure regulating component 32, but is driven by an independent second air pump 331. Through independent programming control of the power module 13, the pressure and inflation / deflation sequence of the second pressure airbag 335 can be distinguished from the first pressure airbag 325, thereby achieving a programmable pressure gradient or wave-like pressure massage effect from the center to the periphery.

[0035] The third pressure regulating component 34 is composed of a third pressure frame 340, which is movably fitted onto the outer circumferential surface of the second pressure frame 330. The top and bottom of the third pressure frame 340 are respectively fixedly connected to a third air distribution plate 343 and a third pressure airbag 345. A third air pump 341 is installed inside the clamping frame 301. The third air pump 341 and the third air distribution plate 343 are connected by a third pipe 342. The third air distribution plate 343 and the third pressure airbag 345 are connected by a number of circumferentially distributed third branch pipes 344.

[0036] The third pressure regulating component 34 serves as the third annular pressure module of the swelling reduction component 3. The third pressure regulating component 34 consists of a third pressure frame 340, a third air pump 341, a third pipe 342, a third air distribution plate 343, a third branch pipe 344, and a third pressure airbag 345. The third pressure frame 340 is movably fitted onto the outer circumference of the second pressure frame 330 through its inner structure, forming another independently movable annular frame. The third air pump 341, which is fixed on the inner wall of the compression frame 301, supplies air to the third air distribution plate 343, which is fixed at the top of the third pressure frame 340, through the third pipe 342. The air is then delivered from the third air distribution plate 343 to the annular third pressure airbag 345, which is attached to the bottom of the frame, through the radially distributed third branch pipes 344. The air pump drives the airbag to inflate and deflate, thereby achieving pressure regulation of the outermost tissues. The concentric nesting design of the four pressure regulating components allows the device to cover a large area from the puncture point to the surrounding area, enabling zoned pressure application.

[0037] The fourth pressure regulating component 35 is composed of a fourth pressure frame 350, which is movably fitted on the outer circumferential surface of the third pressure frame 340. The top and bottom of the fourth pressure frame 350 are respectively fixedly connected to a fourth air distribution plate 353 and a fourth pressure airbag 355. A fourth air pump 351 is installed inside the clamping frame 301. The fourth air pump 351 and the fourth air distribution plate 353 are connected by a fourth pipe 352. The fourth air distribution plate 353 and the fourth pressure airbag 355 are connected by a number of circumferentially distributed fourth branch pipes 354.

[0038] The fourth pressure regulating component 35 includes a fourth pressure frame 350 sleeved on the outer peripheral surface of the third pressure frame 340. The top and bottom of the fourth pressure frame 350 are respectively fixed with a fourth air distribution plate 353 and a fourth pressure airbag 355. The fourth air pump 351, installed at the corresponding position on the inner wall of the compression frame 301, is connected to the fourth air distribution plate 353 through the fourth pipe 352. Multiple air outlets below the fourth air distribution plate 353 are connected to the fourth pressure airbag 355 through the fourth branch pipe 354. Thus, the central pressure regulating component 31 is sequentially surrounded by the first pressure regulating component 32, the second pressure regulating component 33, the third pressure regulating component 34, and the fourth pressure regulating component 35 in a ring, forming a five-ring concentric, nested modular pressure application matrix. The air pump of each component is independently controlled by the control power module 13. According to the preset program or sensor feedback, it can perform inflation and deflation operations of each layer of airbags at different pressures and rhythms, simulating a kneading mechanical massage that spreads from the puncture center point to the surrounding area, so as to achieve the best local swelling reduction effect.

[0039] Flexible bioimpedance sensors 37 are provided at the bottom of the central airbag 313, the first pressure airbag 325, the second pressure airbag 335, the third pressure airbag 345 and the fourth pressure airbag 355. Several circumferentially distributed elastic dampers 36 are provided on the top of the central fixed frame 310, the first pressure frame 320, the second pressure frame 330, the third pressure frame 340 and the fourth pressure frame 350.

[0040] Flexible bioimpedance sensors 37 are embedded on the bottom contact surfaces of the central airbag 313 and the first to fourth pressure airbags 355. The bioimpedance sensors 37 can monitor the changes in the electrical impedance of the skin tissue at their contact points in real time. The degree of tissue edema is related to the impedance value, so the signal can be fed back to the control power module 13 for quantitative assessment of swelling reduction and intelligent adjustment of pressure parameters. At the same time, multiple circumferentially distributed elastic dampers 36 are provided on the top edges of the central fixing frame 310 and the first to fourth pressure frames 350. One end of the elastic damper 36 is connected to each pressure frame, and the other end is connected to the inner top surface of the compression frame 301. In the vertical direction, they provide buffer for each frame layer, making the airbag pressure change more gentle. In the horizontal direction, they allow each frame layer to float and self-adaptively fine-tune within a certain range, ensuring that when the device is strapped to the limb, each annular airbag can better conform to the uneven body surface contour, ensuring uniform pressure application and comfort.

[0041] Working principle: First, medical staff attach the device to the patient's limb using the fixing component 1. Specifically, two rigid pads 11 are unfolded, and the Velcro fasteners 15, which are connected to the connecting shafts 14 at both ends, are wrapped around and secured to the limb. The control power module 13, located on top of one of the rigid pads 11, then takes place. Next, the position is finely adjusted by pressing the component 2. The screw head 24 at the upper end of the transmission screw 23 inside the adjusting block 21 is manually rotated. The transmission screw 23 is converted into axial movement through the internal threaded block 22, which is threaded to it. This causes the lower rotating block 25 and the connecting block 26, which is movably fitted to it, to rise and fall, thereby adjusting the overall height of the swelling reduction component 3 fixed at the bottom of the connecting block 26, ensuring that its bottom fits properly against the skin of the puncture area. After the device is activated, the control power module 13 begins to control the swelling reduction component 3 to work according to a preset program or real-time commands. The core of the swelling reduction process is the coordinated operation of the swelling reduction components 3: First, the central pressure regulating component 31 is activated, and its press-operated air pump 311 operates under control, pumping gas into the central airbag 313 through the first connecting pipe 312, causing it to inflate and apply vertical pressure to the center of the puncture point. Subsequently, the first pressure regulating component 32, the second pressure regulating component 33, the third pressure regulating component 34, and the fourth pressure regulating component 35, which are arranged in a ring from the inside out, are intervened sequentially or as needed. Specifically, the first air pump 321, the second air pump 331, the third air pump 341, and the fourth air pump 351, which are independently installed inside the compression frame 301, are started under control. Gas is delivered sequentially through the first pipe 322, the second pipe 332, the third pipe 342, and the fourth pipe 352 to the first air distribution plate 323, the second air distribution plate 333, the third air distribution plate 343, and the fourth air distribution plate 353 at the top of the corresponding pressure frame. Then, it is evenly introduced into the first pressure airbag 325, the second pressure airbag 335, the third pressure airbag 345, and the fourth pressure airbag 355 at the bottom of the respective pressure frame through the circumferentially distributed first branch pipe 324, the second branch pipe 334, the third branch pipe 344, and the fourth branch pipe 354. This causes the four annular airbags to expand sequentially, forming an annular pressure band radiating from the puncture point to the surrounding tissue. The control power module 13 can be independently programmed to control the inflation and deflation pressure, timing, and rhythm of each air pump. For example, it can achieve gradient pressurization or wave-like alternating inflation and deflation from the central airbag 313 to the fourth pressure airbag 355, simulating a massage motion that spreads from the center outwards. During this process, the flexible bioimpedance sensor 37 embedded in the bottom of each airbag continuously monitors the changes in tissue impedance at the contact site and feeds the data back to the control power module 13 for real-time evaluation of the swelling reduction effect and intelligent adjustment of the operating parameters of each air pump. At the same time, the elastic dampers 36 installed on the central fixing frame 310 and the top of each layer of pressure frame provide buffering and adaptive floating in the vertical and horizontal directions, ensuring that each layer of airbags can conform to the contours of the body surface and apply pressure evenly and comfortably. The air inlet grille 303 set between the pressing frame 301 and the connecting frame 302 continuously provides cooling airflow to each air pump operating inside.Ultimately, through this series of coordinated actions, the device achieves adjustable and feedback-enabled gradient mechanical pressure on the puncture area from point to surface, effectively promoting tissue fluid return and absorption, thereby achieving precise and automated swelling reduction.
