AI Technical Summary
The existing hemostatic compressor for interventional surgery in cardiology is in contact with the interventional duct and wound when positioning, resulting in premature contact between the compressor and the duct, increasing the resistance during the extubation, blocking local blood flow, increasing the risk of tissue ischemia and subcutaneous ecchymosis and hematoma formation, and it is difficult to accurately control the pressure magnitude and duration.
A compression mechanism including a movable chamber and a pressing plate is designed. The magnet repulsive force is used to drive the compression block to slowly approach the wound, and closely adsorb the magnet's attraction, combining the buffer layer and the hemostasis dressing to achieve uniform and stable pressure application. The movable rod and the snap structure quickly adjust the compression force; when the tube is pulled out, the limit buckle design avoids the compression block closing in advance, and the compression block instantly adsorbs the wound under the magnet's attraction, achieving seamless connection; the fixing mechanism and positioning mechanism ensure the stable and precise positioning of the equipment.
A uniform and stable application of pressure is achieved, reducing complications such as bleeding, hematoma or tissue ischemia caused by improper pressure, reducing the risk of subcutaneous ecchymosis and hematoma formation, improving hemostasis efficiency and safety, simplifying operation steps, and reducing the delay in manual adjustment after extubation in traditional processes.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, in particular to a hemostatic compressor for interventional cardiology surgery. Background Art
[0002] Interventional cardiology procedures, with their advantages of minimal trauma and rapid recovery, have become an important treatment for cardiovascular diseases. After the procedure, hemostasis at the puncture site is a critical step in postoperative recovery. Traditional hemostasis methods, such as manual acupressure, not only consume significant time and effort by medical staff, but also make it difficult to precisely control the intensity and duration of pressure. This can easily lead to inadequate hemostasis, resulting in bleeding and hematomas, or excessive pressure, resulting in localized tissue ischemia and necrosis.
[0003] At present, most commonly used hemostatic compressors in clinical practice adopt a design that starts compression after positioning. When the existing compressor is aligned with the wound and positioned, the compression module will contact the interventional tube and the wound, applying pressure in advance. This will cause the compressor to contact the tube prematurely, increase the resistance during tube removal, cause the catheter to deform, and prematurely compress the wound will block local blood flow, leading to tissue ischemia, increasing the risk of subcutaneous ecchymosis and hematoma formation, and prolonging the patient's recovery time.
[0004] Therefore, a hemostatic compressor for cardiology interventional surgery is proposed. Summary of the Invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The present invention uses the mutual repulsion between the first magnet at the bottom of the pressing plate and the second magnet at the top of the passive plate, so that the passive plate drives the compression block to slowly approach the wound, avoiding the impact force of traditional compression methods. The magnets on the opposite sides of the two compression blocks can make them tightly adsorbed after being aligned with the wound. In conjunction with the bottom buffer layer and hemostatic dressing, uniform and stable pressure is applied. The movable rod cooperates with the buckle and the limiter to lock the position of the pressing plate. The structural design of the unlocking plate, the plug and the slot can quickly release the lock to adjust the compression force, meet the hemostasis needs of different patients, and reduce complications such as bleeding, hematoma or tissue ischemia caused by improper pressure.
[0015] The present invention prevents the compression block from closing prematurely by locking the limiting buckle into the groove at the initial position of the compression block, thereby preventing the compression block from contacting the tube during positioning, increasing the resistance to tube removal or blocking blood flow. When removing the tube, the tube clamp slides along the track to drive the limiting buckle out of the groove. The moment the tube is pulled out, the two compression blocks quickly absorb and compress the wound under the action of the magnetic attraction, achieving a seamless connection between tube removal and hemostasis. While reducing the number of operating steps, it avoids the delay of manually adjusting the compressor after tube removal in the traditional process, reduces the risk of subcutaneous ecchymosis and hematoma formation, and improves the efficiency and safety of hemostasis.
[0016] The present invention can flexibly adjust the cable ties and Velcro of the fixing mechanism according to the thickness of the patient's limbs. The soft rubber layer on the inner side of the meniscus enhances the fit, and the air holes improve the wearing comfort, ensuring that the equipment is stably fixed. The ball groove rod, ball joint rod and telescopic sleeve of the limiting mechanism can be adjusted at multiple angles. After the tightening knob is locked, the equipment bracket can adapt to the support requirements of different wound positions. The arc plate of the positioning mechanism rotates around the axis seat through the straight rod, which can fit the skin around the wound to form an arc-shaped positioning reference, assisting medical staff to quickly align the puncture point and avoid poor hemostasis effect caused by compression position deviation. The entire structural design forms a complete system from fixation, support to precise positioning, which improves operational convenience and treatment reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] See also Figures 1 to 8 The present invention provides a technical solution for a hemostatic compressor for interventional cardiology surgery:
[0034] A hemostatic compressor for interventional cardiology surgery includes an equipment bracket 1. The front end of the equipment bracket 1 is provided with a compression mechanism 4 for compressing a wound. The compression mechanism 4 includes a movable chamber 41. The interior of the movable chamber 41 is movably connected to a pressing plate 43. The bottom of the pressing plate 43 is connected to a magnet 44. A slide bar 417 is fixedly connected to one side of the pressing plate 43. A housing 416 is fixedly connected to the slide bar 417. An electric motor 418 is placed inside the housing 416. The magnet 44 is fixedly connected to the output of the electric motor 418. On the output shaft, a start switch of an electric motor 418 is provided on the side of the housing 416, a slide groove 419 matching the slide rod 417 is provided on the side of the equipment bracket 1, and the internal movable connection of the pressing plate 43 is connected to two movable rods 46, and the two movable rods 46 are fixedly connected by a spring 48. A buckle 47 is also movably connected on the side of the movable rod 46, and the rotation connection between the movable rod 46 and the buckle 47 is provided with a torsion spring. A limited position falcon 42 is provided on the inner wall of the movable chamber 41, and the limited position falcon 42 matches the buckle 47, pressing The two sides of the plate 43 are movably connected with the unlocking plate 49, and the pressing plate 43 and the unlocking plate 49 are fixedly connected by the spring 2 410. The side of the unlocking plate 49 is fixedly connected with two plugs 411, and the two ends of the two movable rods 46 are provided with slots 412 that match the plugs 411. When the unlocking plates 49 on both sides of the pressing plate 43 are pressed at the same time, the plugs 411 move into the inside of the slots 412 and drive the two movable rods 46 to move into the inside of the pressing plate 43, so that the buckle 47 is released from the restriction of the limiter 42 and unlocked, and the bottom of the movable compartment 41 is opened. The top of the passive plate 413 is fixedly connected to a second magnet 45 that repels the first magnet 44. The bottom of the passive plate 413 is fixedly connected to two positioning blocks 414, and the two positioning blocks 414 are movably connected to a compression block 415. The opposite sides of the two compression blocks 415 are fixedly connected to magnets that attract each other. The bottom of the compression blocks 415 is fixedly connected to a buffer layer for fitting the skin, and the bottom of the buffer layer is coated with a hemostatic dressing. The side of the unlocking plate 49 is provided with anti-slip friction grooves.
[0035] When working, when it is necessary to compress the wound, the medical staff presses the pressing plate 43 downward. Since the buckles 47 on both sides of the movable rod 46 match the limit falcon 42 and a torsion spring is provided inside, the pressing plate 43 is fixed. At this time, the passive plate 413 moves downward under the repulsive force of magnet 1 44 and magnet 2 45, and drives the compression block 415 at the bottom to approach the wound. Since the magnets on the opposite sides of the two compression blocks 415 attract each other, when the compression blocks 415 contact the skin and align with the wound, the two compression blocks 415 will be tightly adsorbed together, and uniform pressure is applied to the wound through the buffer layer and hemostatic dressing at the bottom to achieve hemostasis. When it is necessary to reduce the pressure or unlock the device, both hands press the unlocking plates 49 on both sides of the pressing plate 43 at the same time. The unlocking plate 49 is forced to move inward by the spring 2 410, and the side plugs 411 are inserted into the slots 412 at both ends of the movable rod 46, driving the two movable rods 4 6 moves toward the inside of the pressing plate 43, so that the buckle 47 on the side of the movable rod 46 disengages from the limit falcon 42 on the inner wall of the movable chamber 41, and the lock of the pressing plate 43 is released. When the patient's wound is compressed for a period of time, the start button on the side of the shell 416 is pressed to start the electric motor 418. At this time, the electric motor 418 drives the magnet 1 44 to rotate. Since the magnetic poles of magnet 1 44 and magnet 2 45 alternately attract or repel each other (at this time, the distance between the pressing plate 43 and the shell 416 is sufficient for magnet 1 44 to flip), alternating compression is formed on the patient's wound. The periodic alternating pressure applied by the compression block 415 simulates the "pumping effect" of human muscle contraction on blood vessels, promotes venous blood flow around the puncture point, reduces the risk of thrombosis caused by blood stasis, and at the same time, alternate compression avoids a single part from being subjected to high pressure for a long time, reduces complications such as skin pressure sores and nerve compression such as the ulnar nerve, and is especially suitable for obese or skin-sensitive patients.
[0036] As an embodiment of the present invention, Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the bottom of the equipment bracket 1 is provided with an extubation mechanism 6 for assisting in extubation, which includes a tube clamp 61 and a track 62 fixed to the bottom of the equipment bracket 1, and the tube clamp 61 slides on the track 62, and a fixing block 63 is fixedly connected to the tube clamp 61, and a long rod 65 is fixedly connected to one side of the fixing block 63, and a clamping tube 66 is sleeved on the outer side of the long rod 65, and one end of the clamping tube 66 is fixedly connected to a limiting buckle 67 for limiting the movement of the two compression blocks 415, and the limiting buckle 67 matches the groove in the middle of the initial position of the two compression blocks 415, so that the tube clamp 61 is stuck on the pipeline. When the tube is pulled out, the tube clamp 61 drives the connecting rod 64 to move through the fixing block 63, and the connecting rod 64 drives the limiting buckle 67 to move through the clamping tube 66, so that the limiting buckle 67 is separated from the middle position of the two compression blocks 415, so that when the pipeline is pulled out, the two compression blocks 415 are instantly adsorbed together to compress the wound;
[0037] During operation, before extubation, the tube clamp 61 is clamped on the interventional tube so that the tube clamp 61 is located at the initial position of the track 62. At this time, the limit buckle 67 is clamped in the groove between the initial positions of the two compression blocks 415, limiting the movement of the compression block 415 to ensure that the compression block 415 will not close the compression tube in advance during the extubation process. When extubation, the medical staff pulls the tube outward, and the tube clamp 61 drives the long rod 65 to slide along the track 62 through the fixed block 63. The clamping tube 66 on the outside of the long rod 65 moves accordingly, driving the limit buckle 67 to disengage from the groove in the middle of the compression block 415. When the tube is completely pulled out, The two compression blocks 415 that are no longer restricted by the limit buckle 67 are instantly attracted together under the attraction of the magnets on the opposite sides, compressing the wound to stop bleeding, avoiding the problem of premature compression of the pipeline and the wound during positioning of the traditional compressor. When the patient is in a supine position, the ball groove rod 31 is adjusted to a perpendicular state with the equipment bracket 1, and the track 62 is perpendicular to the direction of the wound. If the patient is in a left lateral position, after loosening the tightening button 34, the ball groove rod 31 is swung 45 degrees to the left, and the ball joint rod 32 is tilted synchronously, so that the track 62 is consistent with the anatomical direction of the wound, avoiding angle deviation during extubation.
[0038] As an embodiment of the present invention, Figure 1 、 Figure 2 and Figure 7 As shown, a fixing mechanism 2 for fixing is further provided on the side of the equipment bracket 1, and the fixing mechanism 2 includes a fixing seat 21 fixed on both sides of the equipment bracket 1, a round rod 22 is fixedly connected to the fixing seat 21, and the round rod 22 is movably connected to the meniscus 26 through a cable tie 23, one end of the cable tie 23 is fixedly connected to a rotating rod 24, and a rotating groove 25 matching the rotating rod 24 is provided on both sides of the meniscus 26, a Velcro for fixing is fixedly connected to the cable tie 23, and a soft rubber layer is fixedly connected to the inner side of the meniscus 26, and a plurality of small holes for ventilation are provided on the meniscus 26;
[0039] During operation, the fixing mechanism 2 is used to fix the hemostatic compressor on the patient's limb. First, the device bracket 1 is placed near the patient's wound, and the meniscus 26 is wrapped around the patient's limb (such as the wrist or thigh) through the cable tie 23. The Velcro on the cable tie 23 can adjust the tightness to ensure a firm fixation, so that the soft rubber layer on the inside of the meniscus 26 fits the skin of the limb. The multiple breathable holes on the meniscus 26 can promote air circulation, reduce the stuffiness of the patient's limb, and improve comfort.
[0040] As an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, the end of the equipment bracket 1 is movably connected to a limiting mechanism 3 for limiting position. The limiting mechanism 3 includes a ball groove rod 31 rotatably connected to the end of the equipment bracket 1, a ball joint rod 32 movably connected to the bottom of the ball groove rod 31, a telescopic sleeve 33 fixedly connected to the bottom of the ball joint rod 32, and a tightening knob 34 for locking is movably connected to the rotating connection between the ball groove rod 31 and the equipment bracket 1;
[0041] During operation, the limiting mechanism 3 is used to adjust the position and angle of the equipment bracket 1 to adapt to the wound position of different patients. After loosening the tightening knob 34, the ball groove rod 31 can rotate around the end of the equipment bracket 1. At the same time, the ball joint rod 32 can swing in multiple directions at the bottom of the ball groove rod 31. By adjusting the angles of the ball groove rod 31 and the ball joint rod 32, the telescopic sleeve 33 can contact the patient's limbs or bed surface to play a supporting and limiting role. After adjusting to the appropriate position, tighten the tightening knob 34 to fix the rotating connection of the ball groove rod 31 to ensure the stability of the equipment bracket 1 and avoid displacement during the compression process.
[0042] As an embodiment of the present invention, Figure 2 、 Figure 3 and Figure 7 As shown, the front end of the equipment bracket 1 is also provided with a positioning mechanism 5 for auxiliary positioning. The positioning mechanism 5 includes shaft seats 53 fixedly connected to both ends of the equipment bracket 1. Straight rods 52 are movably connected to the two shaft seats 53. Arc plates 51 for positioning are fixedly connected to the straight rods 52.
[0043] During operation, the positioning mechanism 5 is used to assist medical staff to accurately align the wound, rotate the straight rod 52, make the straight rod 52 rotate around the shaft seat 53, adjust the position of the arc plate 51, and fit the arc plate 51 to the skin around the patient's wound. The wound is positioned through the arc structure of the arc plate 51 to ensure that the compression block 415 of the compression mechanism 4 is accurately aligned with the center of the wound. After the positioning is completed, the subsequent extubation and compression operations can be performed through the compression mechanism 4 and the extubation mechanism 6 to improve the accuracy and efficiency of the operation.
[0044] Working principle: When working, first fix the equipment bracket 1 to the patient's limb through the cable tie 23 and Velcro of the fixing mechanism 2. The soft rubber layer on the inside of the meniscus 26 fits the skin, and the breathable holes improve comfort. Then, the arc plate 51 of the positioning mechanism 5 rotates around the shaft seat 53 to assist in aligning the wound. Before extubation, the tube clamp 61 of the extubation mechanism 6 is clamped on the interventional tube, and the limit buckle 67 is clamped into the middle groove of the two compression blocks 415 to limit its movement. When extubating, pull the tube to make the tube clamp 61 slide along the track 62, driving the limit buckle 67 out of the groove. (The bottom of the equipment bracket 1 is fixedly connected to the track 62, and its end is rotatably connected to the equipment bracket 1 through the ball groove rod 31. The ball joint rod 32 at the bottom of the ball groove rod 31 can achieve 360° universal swing, which is matched with the length of the telescopic sleeve 33. Adjustment is performed so that the direction of the track 62 can be adjusted to align with the central axis of the wound according to the patient's body position (such as supine or lateral). During the specific operation, the medical staff first loosens the tightening button 34, and guides the track 62 to be directly above the wound by adjusting the inclination angle of the ball groove rod 31 and the swing angle of the ball joint rod 32, and then tightens the tightening button 34 to fix it, ensuring that the direction of tube removal is consistent with the guidance of the track 62). After the tube is pulled out, the two compression blocks 415 are instantly adsorbed and fitted to compress the wound under the attraction of the magnets on the opposite sides. When the wound needs to be compressed, (the vertical compression force is generated by the repulsive force of magnet 1 44 and magnet 2 45 driving the passive plate 413, and the horizontal adsorption force is provided by the magnet of the compression block 415, and the two are integrated into a composite pressure through the buffer layer), press the pressing plate 43 downward, and the buckles 46 on both sides of the movable rod 46 are fastened. 7 cooperates with the limit falcon 42 to fix the pressing plate 43, and the magnet 1 44 and the magnet 2 45 repel each other so that the passive plate 413 drives the compression block 415 close to the wound and adsorbs it (the determination of the repulsion force between the magnet 1 44 and the magnet 2 45 is consistent with the existing medical application scenarios, and can achieve the hemostatic effect, improve operational safety and patient comfort, and the type and spacing of the magnets are selected based on a limited number of experiments without violating the principles and spirit of the present invention, such as neodymium iron boron magnets). The buffer layer and the hemostatic dressing apply uniform pressure to stop bleeding. (The buffer layer uses a medical-grade silicone material with a thickness of 2-3 mm (such as silicone rubber with a Shore hardness of 30A). Its elastic modulus is small and can be deformed at the moment of magnet adsorption to disperse the local pressure). The two compression blocks 415 The magnets on the opposite side are neodymium iron boron permanent magnets with a pole spacing of 5-8 mm. The adsorption force is converted through the buffer layer to meet the pressure range required for clinical hemostasis). The ball groove rod 31, ball joint rod 32 and telescopic sleeve 33 of the limit mechanism 3 are then used to adjust the position and angle of the device. The tightening knob 34 is rotated to fix it. When the patient's wound is compressed for a period of time, the start button on the side of the shell 416 is pressed to start the electric motor 418. At this time, the electric motor 418 drives the magnet 1 44 to rotate. Since the magnetic poles of magnet 1 44 and magnet 2 45 alternately attract or repel, alternating pressure is formed on the patient's wound. The compression block 415 periodically and alternately applies pressure to simulate the "pumping effect" of human muscle contraction on blood vessels, thereby promoting venous blood flow around the puncture point.Reduce the risk of thrombosis caused by blood stasis. At the same time, alternating compression prevents a single part from being subjected to high pressure for a long time, reducing complications such as skin pressure sores and nerve compression such as the ulnar nerve. To unlock, press the unlocking plate 49, insert the plug 411 into the slot 412, drive the movable rod 46 to move, and the buckle 47 disengages the limiter 42 to release the lock.
[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
