Description

Technical Field

[0001] This invention relates to the field of medical care technology, and more specifically, to a pressure hemostasis device for medical care. Background Technology

[0002] In clinical medical care, effective hemostasis at the puncture site after interventional procedures is crucial for preventing complications. Percutaneous femoral artery puncture, due to its direct approach and ease of operation, has become a routine route for cardiac interventions and angiography. Post-procedure, continuous and stable pressure needs to be applied to the femoral artery puncture site to prevent bleeding or hematoma. Traditional manual compression relies on the physical strength of caregivers, making precise pressure control difficult, and requiring prolonged immobilization of the patient, resulting in poor comfort. Therefore, mechanical femoral artery compression hemostasis devices have emerged. Through adjustable mechanical structures, they replace manual pressure application, achieving standardized pressure application, significantly improving nursing efficiency and safety, and have become a standard post-interventional nursing tool. Their performance directly affects the reliability of hemostasis and the patient's recovery experience.

[0003] Regarding the aforementioned technologies, existing femoral artery compression hemostasis devices face significant technical limitations in practical applications. Their compression components (such as pressure plates or heads) are typically fixed or have limited adjustability, making it difficult to adapt to the complex individual differences in the groin area. Subcutaneous fat thickness, muscle fullness, and physiological curvature vary greatly among patients. For obese patients, a thicker soft tissue layer may lead to excessive dispersion of pressure, resulting in insufficient effective pressure transmitted to the vessel wall and a risk of delayed bleeding. Conversely, for thin or elderly patients, rigid compression components are prone to poor conformation to the skin contour, creating localized gaps or pressure concentration points, potentially causing skin injuries and uneven pressure at the puncture site, leading to unreliable hemostasis. This contradictory state of "poor human-machine fit" makes the device's hemostatic efficacy highly dependent on the operator's experience and repeated adjustments. Furthermore, patients often experience pain, discomfort, and a strong foreign body sensation during compression, resulting in poor comfort. Therefore, a medical nursing compression hemostasis device is proposed. Summary of the Invention

[0004] To address the above problems, the present invention provides a compression hemostasis device for medical care, employing the following technical solution: A pressure hemostasis device for medical care includes a main module and two adapter modules.

An inclined groove is opened inside the rotating column. One of the pull ropes passes through the inclined groove. The swing seat is connected to the flexible pad.

[0008] Furthermore, the movable component also includes two hexagonal seats that are respectively fixedly connected to the front and rear faces of the central block. The front and rear faces of the swing seat are both fixedly connected to fixed rods. The outer surfaces of the two fixed rods are movably fitted with disassembly sleeves. The outer surfaces of the two hexagonal seats are movably fitted with mounting seats. The outer surfaces of the two mounting seats are fixedly connected to second torsion springs. One end of each of the two second torsion springs is fixedly connected to the outer surfaces of the two disassembly sleeves. The outer surfaces of the two hexagonal seats are threaded with mounting bolts.

[0009] Furthermore, the adapter module also includes two blocking plates, which are fixedly connected to the two sides of the top of the central block, and the bottom of the blocking plates contacts the top of the swing seat.

[0010] Furthermore, the steering assembly includes an n-shaped block, a steering block is rotatably connected inside the n-shaped block, the bottom of the steering block is fixedly connected to the top of the center block, a guide rod is rotatably connected inside the steering block, the outer surface of the guide rod contacts the outer surfaces of the two pull ropes, both ends of the steering block extend to the outside of the n-shaped block, and a snap-fit ​​gear is fixedly connected to one end of the steering block.

[0012] Furthermore, the lifting assembly includes a lifting seat movably connected inside the pressing frame, the n-shaped block is fixedly connected to the bottom of the lifting seat, a lifting screw is rotatably connected to the top of the pressing frame, the bottom end of the lifting screw extends into the interior of the pressing frame and is threadedly connected to the interior of the lifting seat, and a rotating block is fixedly connected to the top end of the lifting screw.

[0013] Furthermore, the lifting assembly also includes a lifting groove formed on the outer surface of the pressing frame, an indicator block is slidably connected inside the lifting groove, one end of the indicator block is fixedly connected to the outer surface of the lifting seat, and an indicator groove is formed on one side of the pressing frame, the indicator groove being close to the lifting groove.

[0014] In summary, the present invention has the following beneficial technical effects: (1) The present invention achieves the adaptive fitting function of the pressure contact surface by setting up a central block, movable components, flexible pad, auxiliary wheel and pull rope. Pulling the pull rope can unlock the movable components composed of multiple movable components, so that the swing seat and the flexible pad can flexibly adjust the angle and closely fit the skin contour of the patient's groin area. This design overcomes the problem of pressure dispersion or concentrated pain points caused by the difference in patient body shape in traditional fixed pressure plates. After the joint is locked, the structure is stable, ensuring that the pressure is evenly transmitted to the puncture point, which significantly improves the reliability, safety and patient comfort of hemostasis. Moreover, after use, the structure can be reset with one click, which improves the overall operation convenience and makes the device easier for medical staff to operate and use.

[0015] (2) The present invention, through the setting of steering block, snap-fit ​​gear, snap-fit ​​block and magnetic block, enables the steering block to rotate according to the adjustment of pressure during use, thereby realizing the adjustment of angle, so that the adapter module can continuously fit the patient's skin without the angle changing, and maintain the continuous stability of the pressure.

[0016] (3) This invention provides an intuitive pressure visualization function through the arrangement of a lifting screw, a lifting seat, an indicator block, and an indicator groove. When the lifting screw is rotated to drive the lifting seat to rise or fall, the indicator block fixed on the lifting seat slides within the lifting groove. By comparing the relative positions of the indicator block and the indicator groove on the housing, the operator can quickly determine the approximate pressure range of the compression device. This mechanical indicator structure is simple and reliable, providing a quantitative reference for medical personnel to adjust the pressure, helping to standardize pressure adjustment and reducing the uncertainty of relying on personal experience.

[0022] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0023] Please see Figures 1-8 A pressure hemostasis device for medical care includes a main module 100 and two adapter modules 200. The main module 100 includes a pressure frame 110, with a strap 120 on its outer surface. A lifting assembly 130 is disposed inside the pressure frame 110, and a timer 140 is fixedly connected to the top of the pressure frame 110. The two adapter modules 200 are respectively connected to the bottom of the pressure frame 110 and the lifting assembly 130. Each adapter module 200 includes multiple movable components 230. A steering assembly 210 is connected to the bottom of the lifting assembly 130, and a center block 220 is connected to the bottom of the steering assembly 210. The multiple movable components 230 are horizontal. The components are divided into two groups, with multiple movable components 230 connected to each other in each group. The two groups of movable components 230 are connected to the two sides inside the center block 220, respectively. Each of the two movable components 230 is connected to a closed plate 240, and each of the two closed plates 240 is connected to a pull rope 270 on an adjacent side. The two pull ropes 270 pass through the two groups of movable components 230 and extend into the interior of the steering component 210. A flexible pad 250 is connected between the bottom of the multiple movable components 230 and the bottom of the center block 220. The interior of the center block 220 is rotatably connected to two auxiliary wheels 260, and the two auxiliary wheels 260 contact the outer surfaces of the two pull ropes 270 respectively.

[0024] In use, the staff first places the two adapter modules 200 into contact with the patient's skin, pulls the pull cord 270, which will cause multiple movable components 230 to unlock, pushing the two sets of movable components 230 into contact with the skin, thus allowing the flexible pad 250 to conform to the skin. After the operation is completed, the pull cord 270 is released, and the movable components 230 will self-lock, thus completing the adaptation to the patient. Subsequently, the other adapter module 200 is operated simultaneously to complete the adaptation. After the adaptation is completed, the corresponding puncture is performed. After the puncture, both adapter modules 200 are placed in contact with the patient, with one adapter module 200 placed at the designated pressure point. Then, the strap 120 is tied, and the locking state of the steering component 210 is released. Then, the lifting component 130 is rotated, and the lifting component 130 will be raised to adjust the pressure of one of the adapter modules 200 on the designated area, so that the pressure can be adjusted as needed. During the compression, the timer 140 can be used to set the compression time. After the set time is reached, an alarm will sound to ensure the accuracy of the compression time.

[0025] The movable component 230 includes a steering cylinder 231 rotatably connected between the front and rear faces of the inner wall of the central block 220. A swing seat 2312 is fixedly connected to the outer surface of the steering cylinder 231. Two fixed plates 232 are fixedly connected inside the steering cylinder 231. A rotating column 233 is rotatably connected between the interiors of the two fixed plates 232. A first torsion spring 234 is fixedly connected between the front and rear faces of the two fixed plates 232 and the outer surface of the rotating column 233. The movable component 230 also includes two engaging sleeve grooves 237 respectively opened on the front and rear faces of the central block 220. Two connecting sleeve grooves 235 are opened inside the steering cylinder 231. The interiors of the two connecting sleeve grooves 235 are movable. The rotating component 230 is connected to two steering gear teeth 236, which are movably connected to the interior of two snap-fit ​​tooth grooves 237. The movable component 230 also includes two sleeves 2310 that are fixedly connected to both ends of the rotating column 233. A knob rod 238 is fixedly connected to the adjacent side of each of the two steering gear teeth 236. Two knob grooves 239 are opened on the outer surface of each of the two knob rods 238. Two inner connecting blocks 2311 are fixedly connected to the interior of each of the two sleeves 2310. The four inner connecting blocks 2311 are movably connected to the interior of the four knob grooves 239. An inclined groove is opened inside the rotating column 233, and a pull rope 270 passes through the inclined groove. The swing seat 2312 is connected to the flexible pad 250.

[0026] Pulling the pull cord 270 will cause multiple rotating columns 233 to rotate. During the rotation of the rotating columns 233, the first torsion spring 234 will be twisted. At this time, the sleeve 2310 will drive the inner connecting block 2311 to rotate. The inner connecting block 2311 will slide inside the knob groove 239, thereby pulling the knob rod 238 and the steering gear 236 to move. The steering gear 236 will disengage from the engaging sleeve groove 237. At this time, the multiple steering cylinders 231 will be unlocked and can rotate. The multiple swing seats 2312 are rotated to contact the patient's skin, so that the flexible pad 250 fits the skin. After the operation is completed, the pull rope 270 is released, and the first torsion spring 234 drives the rotating column 233 to reset, thereby driving the sleeve 2310 and the inner connecting block 2311 to rotate. The inner connecting block 2311 pushes the steering sleeve tooth 236 to engage with the locking sleeve tooth groove 237 by sliding inside the knob groove 239, thereby locking the multiple moving components 230 and thus completing the adaptation to the patient.

[0027] The movable component 230 also includes two hexagonal seats 2313 fixedly connected to the front and rear faces of the central block 220, respectively. A fixing rod 2317 is fixedly connected to both the front and rear faces of the swing seat 2312. A disassembly sleeve 2318 is movably fitted onto the outer surface of each of the two fixing rods 2317. A mounting base 2314 is movably fitted onto the outer surface of each of the two hexagonal seats 2313. A second torsion spring 2315 is fixedly connected to the outer surface of each of the two mounting bases 2314. One end of each second torsion spring 2315 is fixedly connected to the outer surface of the two disassembly sleeves 2318, respectively. The outer surfaces of the two hexagonal seats 2313 are threaded. The adapter module 200 is connected with mounting bolts 2316 and also includes two blocking plates 280. The two blocking plates 280 are fixedly connected to the two sides of the top of the center block 220. The bottom of the blocking plates 280 contacts the top of the swing seat 2312. When the second torsion spring 2315 is damaged after long-term use, the mounting bolts 2316 can be rotated, and then the mounting bracket 2314 can be removed from the hexagonal seat 2313. The disassembly sleeve 2318 will also be removed from the fixing rod 2317, thereby completing the disassembly of the second torsion spring 2315. The second torsion spring 2315 can be replaced by reversing the above steps.

[0028] When the swing seat 2312 swings, the fixed rod 2317 will drive the disassembly sleeve 2318 to swing. After the disassembly sleeve 2318 swings, it will drive the second torsion spring 2315 to deform. Subsequently, it will engage with the steering gear 236 to lock the state in the slot 237 of the engaging sleeve. After the hemostasis operation is completed, the pull rope 270 will be pulled. The pull rope 270 will drive the steering gear 236 to retract from the slot 237 of the engaging sleeve. At this time, the second torsion spring 2315 will return to its original state, thereby pushing the fixed rod 2317. The fixed rod 2317 will drive the swing seat 2312 to swing and reset. This allows multiple moving components 230 to automatically reset after the hemostasis operation. The multiple moving components 230 are in contact with the two blocking plates 280 respectively to avoid over-reset, thus facilitating the next hemostasis operation.

[0029] The steering assembly 210 includes an n-shaped block 211, with a steering block 212 rotatably connected inside the n-shaped block 211. The bottom of the steering block 212 is fixedly connected to the top of the center block 220. A guide rod 213 is rotatably connected inside the steering block 212, and the outer surface of the guide rod 213 contacts the outer surfaces of the two pull ropes 270. Both ends of the steering block 212 extend to the outside of the n-shaped block 211. A locking gear 214 is fixedly connected to one end of the steering block 212. The steering assembly 210 also includes a hollow block 215 fixedly connected to one side of the n-shaped block 211. A locking block 216 is slidably connected inside the hollow block 215, and one end of the locking block 216 is movable. The outer surface of the locking gear 214 is engaged. The top of the locking block 216 and the top of the inner wall of the hollow block 215 are both connected to magnetic blocks 218. A movable spring 217 is fixedly connected between the top of the locking block 216 and the top of the inner wall of the hollow block 215. The lifting assembly 130 includes a lifting seat 131 movably connected inside the pressing frame 110. An n-shaped block 211 is fixedly connected to the bottom of the lifting seat 131. A lifting screw 132 is rotatably connected to the top of the pressing frame 110. The bottom end of the lifting screw 132 extends into the interior of the pressing frame 110 and is threadedly connected to the interior of the lifting seat 131. A rotating block 133 is fixedly connected to the top end of the lifting screw 132.

[0030] Pulling the locking block 216 upwards disengages it from the locking gear 214, while the hollow block 215 retracts and the two magnetic blocks 218 connect, thereby releasing the locking state of the steering block 212. Then, by rotating the lifting screw 132 through the rotating block 133, the lifting seat 131 gradually extends to the outside of the pressing frame 110, thereby increasing the pressure of one of the adapter modules 200 on the designated part, and the steering block 212 will rotate accordingly. After the adjustment is completed, pulling the locking block 216 back into the locking gear 214 locks the steering block 212, allowing the pressure to be adjusted as needed, improving the overall applicability.

[0031] The lifting assembly 130 also includes a lifting groove 134 formed on the outer surface of the pressing frame 110. An indicator block 135 is slidably connected inside the lifting groove 134. One end of the indicator block 135 is fixedly connected to the outer surface of the lifting seat 131. An indicator groove 136 is formed on one side of the pressing frame 110. The indicator groove 136 is close to the lifting groove 134.

[0032] During the adjustment process, the indicator block 135 will slide inside the lifting groove 134. By comparing the positions of the indicator block 135 and the indicator groove 136, the approximate pressure value can be known, which is convenient for the staff to make adjustments.

[0033] The implementation principle of this invention is as follows: During use, the operator first places the two adapter modules 200 into contact with the patient's skin and pulls the pull cord 270. The pull cord 270 will drive multiple rotating columns 233 to rotate. During the rotation of the rotating columns 233, the first torsion spring 234 will be twisted. At this time, the sleeve 2310 drives the inner connecting block 2311 to rotate. The inner connecting block 2311 will slide inside the knob groove 239, thereby pulling the knob rod 238 and the steering gear 236 to move. The steering gear 236 will disengage from the engaging sleeve groove 237, at which point the multiple steering cylinders 231 will be unlocked. The rotating mechanism pushes multiple swing seats 2312 to rotate and contact the patient's skin, allowing the flexible pad 250 to adhere to the skin. During the swing, the fixed rod 2317 drives the disassembly sleeve 2318 to swing. After the disassembly sleeve 2318 swings, it causes the second torsion spring 2315 to deform. After the operation is completed, the pull rope 270 is released, and the first torsion spring 234 drives the rotating column 233 to return to its original position, thereby causing the sleeve 2310 and the inner connecting block 2311 to rotate. The inner connecting block 2311 slides inside the knob groove 239 to push the steering gear 236 into the snap-fit ​​sleeve. The toothed groove 237 locks multiple movable components 230, thus completing the adaptation to the patient. Simultaneously, another adaptation module 200 completes the adaptation. After adaptation, a corresponding puncture is performed. After the puncture, both adaptation modules 200 are brought into contact with the patient, with one adaptation module 200 placed at the designated pressure point. Then, the strap 120 is applied, and the locking block 216 is pulled upwards to disengage the locking gear 214. Simultaneously, the hollow block 215 retracts, and the two magnetic blocks 218 connect, thereby releasing the locking state of the steering block 212. Then, the lifting screw 1 is rotated via the rotating block 133. 32. This causes the lifting seat 131 to gradually extend to the outside of the pressing frame 110, thereby increasing the pressure of one of the adapter modules 200 on the designated part. The steering block 212 will rotate accordingly. After adjustment, pulling the locking block 216 re-engages it with the locking gear 214 to lock the steering block 212. This allows the pressure to be adjusted as needed, improving overall applicability. During adjustment, the indicator block 135 will slide inside the lifting groove 134. By comparing the positions of the indicator block 135 and the indicator groove 136, the approximate pressure value can be determined, facilitating adjustment by the operator.After the pressure hemostasis operation is completed, the needle is removed to complete the entire procedure. Subsequently, after the pressure hemostasis operation is completed, the strap 120 is untied to disassemble the device. Pulling the pull rope 270 will cause the steering gear 236 to retract from the locking sleeve groove 237. At this time, the second torsion spring 2315 will return to its original state, thereby pushing the fixed rod 2317. The fixed rod 2317 will then cause the swing seat 2312 to swing and reset, allowing multiple moving components 230 to automatically reset after the pressure hemostasis operation. Each moving component 230 contacts one of the two blocking plates 280 to prevent excessive reset.

[0034] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
