Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a radial artery compressor for cardiology nursing and its compression method. Background Technology

[0002] Because the radial artery approach has advantages such as minimal invasiveness, fewer intraoperative complications, and faster postoperative recovery during interventional treatment, radial artery puncture intervention has become the most commonly used interventional treatment method for cardiovascular diseases such as coronary heart disease.

[0003] A common radial artery compressor is the spiral compression type, which consists of a fixation strap, a dial, a spiral handle, and a pressure plate. It is an externally worn hemostatic device. To use it, the radial artery compressor is first secured to the wrist with the strap, and then the spiral handle is rotated to apply pressure directly downwards to the radial artery puncture site, ultimately achieving hemostasis. As can be seen, this process requires first securing the strap, then tightening, and finally applying pressure, which is inconvenient, time-consuming, and results in slow hemostasis, potentially leading to excessive blood loss in the patient.

[0004] To mitigate the aforementioned effects, the present invention provides a radial artery compressor for rapid hemostasis in cardiology nursing and a method thereof. Summary of the Invention

[0005] To overcome the drawbacks of existing radial artery compressors, which are cumbersome to use and result in slow hemostasis, this invention provides a radial artery compressor for rapid hemostasis in cardiology nursing and its compression method.

[0006] A radial artery compressor for cardiology nursing includes a housing, a symmetrically distributed fixing frame fixed to the housing, a motor fixed to the housing, a first gear fixed to the output shaft of the motor, symmetrically distributed sliders slidably connected to the housing, a rotating shaft rotatably connected to the housing, a second gear fixed to the rotating shaft, the second gear meshing with the first gear, symmetrically distributed screws fixed to the rotating shaft, the screws being threadedly connected to adjacent sliders, a clamping plate rotatably connected to the fixing frame, a connecting plate rotatably connected to the clamping plate, and a connecting plate rotatably connected to adjacent sliders. The housing is provided with a downward pressure component for automatically applying downward pressure to the radial artery puncture site for hemostasis, and a rolling component for automatically squeezing outwards the blood near the radial artery puncture site for hemostasis.

[0007] In one embodiment, the pressing assembly includes symmetrically distributed first elastic telescopic rods, each of which is fixedly connected to the outer shell. A pressure plate is fixedly connected between the telescopic ends of the symmetrically distributed first elastic telescopic rods. The pressure plate is slidably connected to the outer shell. A limit frame is fixedly connected to the pressure plate. A pull rod is fixedly connected to the clamping plate near the limit frame. The pull rod is in a limiting engagement with the pressure plate.

[0008] In one embodiment, the rolling assembly includes symmetrically distributed second elastic telescopic rods, all of which are fixed to the housing. The telescopic portion of each second elastic telescopic rod has multiple sections. A symmetrically distributed first fixing block and a symmetrically distributed second fixing block are fixed between the telescopic portions of adjacent second elastic telescopic rods. The first fixing block and the second fixing block are respectively fixed to the telescopic portions of adjacent sections. A first pressure roller is rotatably connected between adjacent first fixing blocks, and a second pressure roller is rotatably connected between adjacent second fixing blocks.

[0009] In one embodiment, the radial artery compressor and its compression method for cardiology nursing further includes a folding plate, the folding plate being rotatably connected to the first fixing block on one side, the folding plates being rotatably connected to each other in a symmetrically distributed manner, and the folding plate being pressed against the adjacent clamping plate.

[0010] In one embodiment, the radial artery compressor and its compression method for cardiology nursing further includes a first fixed rod, the first fixed rod being fixedly connected to a first fixed block, a lifting plate being slidably connected between adjacent first fixed rods, a first spring being fixedly connected between the lifting plate and adjacent first fixed rods, a telescopic plate being fixedly connected to the lifting plate, and a wedge plate being fixedly connected to the telescopic end of the telescopic plate, the wedge plate engaging with an adjacent second pressure roller.

[0011] In one embodiment, the radial artery compressor and its compression method for cardiology nursing further includes symmetrically distributed second fixing rods, each of which is fixedly connected to the clamp on one side. A lifting rod is slidably connected between the symmetrically distributed second fixing rods, and a second spring is fixedly connected between the second fixing rod and the lifting rod. A wedge-shaped member is fixedly connected to the clamp on the other side, and the wedge-shaped member is in a pressing fit with the lifting rod.

[0012] In one embodiment, the wedge is serrated to adjust the tightness of the clamping plate.

[0013] In one embodiment, the radial artery compressor and its compression method for cardiology nursing further includes an insert rod inserted into the compression plate, the insert rod being threadedly connected to a knob, and the insert rod being threadedly connected to a replacement compression plate.

[0014] In one embodiment, the pressure plate has a slot that matches the replacement pressure plate.

[0015] A radial artery compression method for cardiology nursing care specifically includes the following steps:

[0016] S1: Control the output shaft of the motor to drive the first gear to rotate, so that the clamping plate rotates upward to fully open;

[0017] S2: Control the output shaft of the motor to stop rotating, and place the compressor on the radial artery bleeding point on the wrist;

[0018] S3: Control the output shaft of the motor to drive the first gear to rotate in the opposite direction, so that the clamp rotates downwards until it just locks the patient's wrist, and then control the output shaft of the motor to stop rotating.

[0019] By adopting the above technical solution, the present invention has at least the following advantages:

[0020] 1. This invention can be adjusted and worn independently according to the wrist size of different patients. When the compression device is adjusted and put on the wrist, it automatically applies downward pressure to the radial artery puncture point through the compression plate to stop bleeding. This greatly reduces the cumbersome intermediate wearing and hemostasis process, speeds up the hemostasis speed, and avoids wasting time and causing untimely hemostasis, which could lead to excessive blood loss in the patient.

[0021] 2. The present invention utilizes the compression of the clamping plate and the folding plate to achieve hemostasis when the device is fastened to the wrist. In addition to applying downward pressure to the radial artery puncture point through the compression plate, it also uses the first and second pressure rollers to sequentially squeeze outwards the blood near the radial artery puncture point to achieve hemostasis, thereby improving the hemostasis effect.

[0022] 3. This invention uses the first and second pressure rollers to sequentially squeeze the blood outwards from the radial artery puncture site to stop bleeding, while also using a telescopic plate to move downwards and press on the radial artery next to the puncture site to stop bleeding, further improving the hemostatic effect.

[0023] 4. This invention uses the lifting rod and wedge-shaped piece to press together, so that the splint fits on the patient's wrist and automatically locks the splint, preventing the splint from easily rotating and opening, which would cause the compressor to fall off the wrist.

[0024] 5. This invention applies pressure downwards to the radial artery puncture site to achieve hemostasis by replacing the pressure plate with a replacement pressure plate. The replacement pressure plate can be quickly installed and removed by turning a knob, making it easy to replace with a new replacement pressure plate and preventing cross-infection between blood vessels.

Detailed Implementation

[0038] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0039] Example 1: A radial artery compressor for cardiology nursing, combined with... Figure 1 To be continued Figure 3 The system includes a housing 1, to which symmetrically distributed mounting brackets 101 are fixedly connected. A motor 102 is fixedly connected to the front side of the housing 1. A first gear 103 is fixedly connected to the output shaft of the motor 102. Sliding blocks 106 are symmetrically distributed on both sides of the housing 1. A rotating shaft is rotatably connected to the front part of the housing 1 near the first gear 103. A second gear 104 is fixedly connected to the rotating shaft and meshes with the first gear 103. Screws 105 are symmetrically distributed on both sides of the rotating shaft. 105 is threadedly connected to the adjacent slider 106. The fixing frame 101 is rotatably connected to a clamping plate 108 for holding the wrist. The clamping plate 108 is rotatably connected to a connecting plate 107. The connecting plate 107 is rotatably connected to the adjacent slider 106. The outer shell 1 is provided with a pressing component, which is used to automatically apply downward pressure to the radial artery puncture point for hemostasis. The outer shell 1 is provided with a rolling component, which is used to automatically squeeze the blood next to the radial artery puncture point outwards for hemostasis.

[0040] Combined with appendix Figure 4 To be continued Figure 5 The pressing assembly includes a first elastic telescopic rod 2 symmetrically distributed front and rear. The first elastic telescopic rod 2 symmetrically distributed front and rear are all fixed to the outer shell 1. A pressure plate 201 is fixed between the telescopic ends of the first elastic telescopic rod 2 symmetrically distributed front and rear. The pressure plate 201 is slidably connected to the outer shell 1. A limit frame 202 is fixed to the right side of the pressure plate 201. A pull rod 203 is fixed to the upper outer side of the clamping plate 108 on the right side. The pull rod 203 is limited and engaged with the pressure plate 201.

[0041] When using this compressor for hemostasis, the medical staff first controls the output shaft of the motor 102 to drive the first gear 103 to rotate. The first gear 103 drives the second gear 104 to rotate, the second gear 104 drives the rotating shaft to rotate, the rotating shaft drives the screw 105 to rotate, the screw 105 drives the slider 106 to move outward, and the slider 106 drives the clamping plate 108 to rotate upward through the connecting plate 107. When the clamping plate 108 rotates upward to fully open, the output shaft of the motor 102 is stopped, and the compressor is then fastened. At the radial artery bleeding point on the wrist, the output shaft of the motor 102 is controlled to drive the first gear 103 to rotate in the opposite direction. The first gear 103 drives the second gear 104 to rotate in the opposite direction. The second gear 104 drives the rotating shaft to rotate in the opposite direction. The rotating shaft drives the screw 105 to rotate in the opposite direction. The screw 105 drives the slider 106 to move inward. The slider 106 drives the clamp 108 to rotate downward through the connecting plate 107. When the clamp 108 rotates downward until it just locks the patient's wrist, the output shaft of the motor 102 is controlled to stop rotating.

[0042] During the above operation, when the clamp 108 on the right side swings upward, it will cause the pull rod 203 to rotate upward. The pull rod 203 releases the limiting frame 202. At this time, the first elastic telescopic rod 2, which is in a stretched state, returns to its original position and causes the compression plate 201 to move upward. When the clamp 108 on the right side swings downward, it will cause the pull rod 203 to rotate downward. The pull rod 203 pulls the limiting frame 202 downward. The limiting frame 202 causes the compression plate 201 to move downward, so that the first elastic telescopic rod 2 is stretched. At this time, the compression plate 201 applies downward pressure to the radial artery puncture point to achieve hemostasis.

[0043] In summary, the present invention can be adjusted and worn independently according to the wrist size of different patients. When the compression device is adjusted and put on the wrist, it automatically applies downward pressure to the radial artery puncture point through the compression plate 201 to stop bleeding, which greatly reduces the cumbersome intermediate wearing and hemostasis process, avoids wasting time and causing untimely hemostasis, and thus avoids excessive blood loss in patients.

[0044] Combined with appendix Figure 6 To be continued Figure 7The rolling assembly includes two symmetrically distributed second elastic telescopic rods 3, which are fixed to the front and rear sides of the outer casing 1. The telescopic part of the second elastic telescopic rod 3 is configured as two sections. A first fixing block 31 and a second fixing block 32, which are symmetrically distributed, are fixed between the telescopic parts of adjacent second elastic telescopic rods 3. The first fixing block 31 and the second fixing block 32 are fixed to the telescopic parts of the second section and the first section, respectively. A first pressure roller 301 is rotatably connected between adjacent first fixing blocks 31, and a second pressure roller 302 is rotatably connected between adjacent second fixing blocks 32. A folding plate 303 is rotatably connected to the first fixing block 31 on the right side. The folding plates 303, which are symmetrically distributed front and rear, are rotatably connected. The folding plates 303 are pressed together with the clamping plate 108 on the right side.

[0045] To dislodge the blood near the radial artery puncture site, the specific operation is as follows: During the above operation, when the right-side clamp 108 swings upward and disengages from the folding plate 303, the clamp 108 no longer presses against the folding plate 303. This causes the extension parts of the second elastic telescopic rod 3, which is in a stretched state, to sequentially reset through their own elasticity, driving the first fixing block 31 and the second fixing block 32 to move inward in sequence. The first fixing block 31 drives the folding plate 303 to fold inward, and the first fixing block 31 drives the first pressure roller 301 to move inward. The second fixing block 32 drives the second pressure roller 302 to move inward. When the right-side clamp 108... When the clamping plate 108 swings downward and contacts the folding plate 303, the clamping plate 108 on the right side squeezes the folding plate 303, causing the folding plate 303 to pull the first fixing block 31 on the right side outward. The first fixing block 31 on the right side drives the first pressure roller 301 to roll outward, causing the telescopic parts of the second section and the first section of the second elastic telescopic rod 3 to extend in sequence. The telescopic part of the first section of the second elastic telescopic rod 3 drives the second fixing block 32 to move outward. The second fixing block 32 drives the second pressure roller 302 to roll outward. Thus, when the clamping plate 108 is adjusted, the first pressure roller 301 and the second pressure roller 302 roll outward in sequence.

[0046] In summary, the present invention, through the squeezing and cooperation of the clamping plate 108 and the folding plate 303, enables the compressor to stop bleeding when the wrist is fastened. In addition to applying downward pressure to the radial artery puncture point through the compression plate 201, it can also stop bleeding by sequentially squeezing outwards the blood near the radial artery puncture point through the first pressure roller 301 and the second pressure roller 302, thereby improving the hemostatic effect.

[0047] Example 2: Based on Example 1, combined with Appendix Figure 8 To be continued Figure 9 The radial artery compressor and its compression method for cardiology nursing also include a first fixed rod 4, which is fixedly connected to the first fixed block 31. A lifting plate 401 is slidably connected between adjacent first fixed rods 4. A first spring 402 is fixedly connected between the lifting plate 401 and the adjacent first fixed rod 4. A telescopic plate 403 is fixedly connected to the lifting plate 401. A wedge plate 404 is fixedly connected to the telescopic end of the telescopic plate 403. The wedge plate 404 is in a pressing fit with the adjacent second pressure roller 302.

[0048] To achieve hemostasis by applying pressure to the radial artery next to the puncture point, the specific operation is as follows: When the first fixing block 31 moves inward relative to the second fixing block 32, the outermost telescopic part of the second elastic telescopic rod 3 contracts first, causing the first fixing block 31 to drive the first fixing rod 4 to move inward. The first fixing rod 4 drives the lifting plate 401 to move inward, the lifting plate 401 drives the telescopic plate 403 to move inward, the telescopic plate 403 drives the wedge plate 404 to move inward, the wedge plate 404 squeezes the second pressure roller 302 to rotate, thereby driving the wedge plate 404 to move upward. The wedge plate 404 drives the telescopic plate 403 to move upward, and the telescopic plate 403 drives the lifting plate 401 to move upward. The first spring 402 is stretched, causing the telescopic plate 403 to rest on the adjacent second pressure roller 302. When the wedge plate 404 moves to the innermost side, it is blocked by the outer shell 1. When the telescopic plate 403 continues to move inward, it will contract.

[0049] When the first fixing block 31 moves outward relative to the second fixing block 32, the outermost telescopic rod of the second elastic telescopic rod 3 first resets, causing the first fixing block 31 to drive the first fixing rod 4 to move outward. The first fixing rod 4 drives the lifting plate 401 to move outward. The lifting plate 401 drives the telescopic plate 403 to move outward. The telescopic plate 403 drives the wedge plate 404 to move outward. The wedge plate 404 gradually disengages from the adjacent second pressure roller 302. The first spring 402 resets, driving the lifting plate 401 to move downward. The lifting plate 401 drives the telescopic plate 403 to move downward and press on the radial artery next to the puncture point. When the wedge plate 404 moves and disengages from the outer shell 1, the telescopic plate 403 will gradually reset.

[0050] In summary, the present invention uses the first pressure roller 301 and the second pressure roller 302 to sequentially squeeze the blood near the radial artery puncture point to stop bleeding, while the telescopic plate 403 moves downward to press on the radial artery next to the puncture point to stop bleeding, thereby further improving the hemostatic effect.

[0051] Example 3: Based on Example 2, combined with Appendix Figure 10 The radial artery compressor and its compression method for cardiology nursing also include a second fixing rod 5 symmetrically distributed front and back. The second fixing rods 5 symmetrically distributed front and back are all fixed to the clamp plate 108 on the right side. A lifting rod 501 is slidably connected between the second fixing rods 5 symmetrically distributed front and back. A second spring 502 is fixed between the second fixing rod 5 and the lifting rod 501. A wedge 503 is fixed to the clamp plate 108 on the left side. The wedge 503 is set in a sawtooth shape and is used to adjust the locking degree of the clamp plate 108. The wedge 503 and the lifting rod 501 are in a pressing fit.

[0052] After the splint 108 is fastened to the patient's wrist, if the motor 102 is de-energized, the splint 108 may easily loosen. To avoid this, the splint 108 needs to be locked. The specific operation is as follows: During the downward rotation of the splint 108 to lock the patient's wrist, the left and right splints 108 respectively drive the wedge-shaped member 503 and the second fixing rod 5 to move closer to each other. The second fixing rod 5 drives the lifting rod 501 to move closer to the wedge-shaped member 503. Under the squeezing action of the serrated edge of the wedge-shaped member 503, the lifting rod 501 slides downward along the second fixing rod 5, and the second spring... When the spring 502 is compressed, and the lifting rod 501 moves between the adjacent teeth of the wedge 503, the second spring 502 resets, causing the lifting rod 501 to slide upwards along the second fixed rod 5 to reset. Depending on the degree of clamping of the clamping plate 108, the lifting rod 501 will lock between the adjacent teeth of the wedge 503, thus locking the clamping plate 108. When unlocking is required, the lifting rod 501 is manually pulled downwards so that the lifting rod 501 no longer jams the wedge 503, and then the clamping plate 108 is driven upwards by the motor 102 to open.

[0053] In summary, the present invention, through the pressing and engaging of the lifting rod 501 and the wedge-shaped member 503, enables the clamp 108 to be properly fastened on the patient's wrist while automatically locking the clamp 108, preventing the clamp 108 from easily rotating and opening, thus preventing the compressor from falling off the wrist.

[0054] Combined with appendix Figure 5 Appendix Figure 11 To be continued Figure 12The radial artery compressor and its compression method for cardiology nursing also include an insertion rod 601, which is inserted through the middle of the compression plate 201. A knob 6 is threaded to the upper part of the insertion rod 601, and a replacement pressure plate 602 is threaded to the bottom end of the insertion rod 601. The compression plate 201 has a slot, and the slot of the compression plate 201 matches the size of the replacement pressure plate 602.

[0055] Hemostasis is achieved solely through the fixed compression plate 201, requiring timely disinfection and cleaning. However, if the compression device is urgently needed but disinfection and cleaning are inconvenient, it must be reused, which carries the risk of cross-infection. To avoid this, the following procedure is performed: When the compression plate 201 moves downward, it drives the insertion rod 601 downward, which in turn drives the replacement compression plate 602 downward. At this time, the replacement compression plate 602 replaces the compression plate 201 in applying pressure downward to the radial artery puncture site to achieve hemostasis. After use, the knob 6 is unscrewed, and the insertion rod 601 is pulled out of the compression plate 201. The replacement compression plate 602 is removed along with the insertion rod 601. Then, the used replacement compression plate 602 is unscrewed, a new replacement compression plate 602 is installed, the insertion rod 601 is reinserted into the compression plate 201, and the knob 6 is screwed back on.

[0056] In summary, the present invention uses the replacement pressure plate 602 to apply downward pressure to the radial artery puncture site in place of the pressure plate 201 to achieve hemostasis. The replacement pressure plate 602 can be quickly disassembled and assembled using the knob 6, which facilitates the replacement of the new replacement pressure plate 602 and prevents cross-infection between blood vessels.

[0057] Example 4: Based on Example 3, a radial artery compression method for cardiology nursing specifically includes the following steps:

[0058] S1: Control the output shaft of the motor 102 to drive the first gear 103 to rotate, so that the clamping plate 108 rotates upward to fully open;

[0059] S2: Control the output shaft of the motor 102 to stop rotating, and place the compressor on the radial artery bleeding point on the wrist;

[0060] S3: Control the output shaft of the motor 102 to drive the first gear 103 to rotate in the opposite direction, so that the clamp 108 rotates downwards until it just locks the patient's wrist, and then control the output shaft of the motor 102 to stop rotating.

[0061] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Contents not described in detail in this invention belong to existing technology known to those skilled in the art.
