Description

Technical Field

[0001] This invention relates to the field of clinical hemostasis technology, specifically to a clinical compression hemostasis device. Background Technology

[0002] Clinical compression hemostasis is the most basic and crucial hemostasis method in medical scenarios such as surgery, trauma emergency care, and interventional therapy. It is widely used in multiple medical fields such as orthopedics, general surgery, cardiology, emergency medicine, and geriatric care. Its core principle is to apply physical pressure directly to the bleeding site, compress the damaged blood vessel wall, promote platelet aggregation and thrombus formation, thereby blocking blood outflow and achieving rapid hemostasis.

[0003] For example, Chinese patent application number 202411207426.4 discloses an arterial compression hemostat, including a compression main board and a fixing band assembly. The compression main board includes a first, second, and third base plate. The first and second base plates are slidably connected and their positions are adjustable to change the length of the compression main board. At least two compression components are provided on the third base plate along the arterial direction. A clamping member is provided on one end of the second base plate, which can clamp and press against the sides of the wrist or thigh on both sides of the compression point. The fixing band assembly is provided on the second base plate and includes a fixing band and a tightening component. The tightening component is used to keep the fixing band in a tightened state during use.

[0004] Existing compression hemostasis devices often require separate operation for fixing and driving the pressure plate, which is not only cumbersome but also reduces the efficiency of compression hemostasis. Therefore, to address these technical problems, a clinical compression hemostasis device is proposed. Summary of the Invention

[0020] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0021] Please see Figure 1 and Figure 2 A clinical compression hemostasis device according to one embodiment includes a mounting plate 10, a fixing assembly, a rotating shaft 30, a pressure plate 40, and a transmission mechanism. The mounting plate 10 has a mounting cavity 101 and a through groove 102 extending along its thickness. The fixing assembly includes take-up rollers 20 and fixing belts 201. Take-up rollers 20 are rotatably mounted at both ends of the mounting cavity 101, and the fixing belts 201 extend from both ends of the mounting plate 10 into the mounting cavity 101 and connect to the two sets of take-up rollers 20. The rotating shaft 30 is rotatably mounted on the mounting plate 10. The pressure plate 40 is slidably mounted on the mounting plate 10 along its thickness and can pass through the through groove 102. The transmission mechanism connects the mounting plate 10, the pressure plate 40, and the two sets of take-up rollers 20. Rotation of the rotating shaft 30 drives the two sets of take-up rollers 20 to rotate first, and then drives the pressure plate 40 to move.

[0022] In the above embodiment, the mounting plate 10 and the fixing strap 201 are together fitted onto the bleeding site, and the pressure plate 40 is aligned with the bleeding opening. Then, the rotating shaft 30 is rotated. The rotation of the rotating shaft 30 drives two sets of winding rollers 20 to rotate through the transmission mechanism. The rotation of the two sets of winding rollers 20 can wind up the fixing strap 201 to fix the mounting plate 10 to the bleeding site. Then, the transmission mechanism drives the pressure plate 40 to move downward. The downward movement of the pressure plate 40 can press the bleeding opening, thereby achieving the purpose of compression hemostasis. By rotating the rotating shaft 30, the continuous operation of fixing the device and compression hemostasis can be realized. It is simple to operate and improves the efficiency of compression hemostasis.

[0023] Please refer to the following: Figures 3 to 7Specifically, the transmission mechanism includes a first bevel gear 50, a first transmission assembly, a first spring 501, and a second transmission assembly. A spiral guide groove 301 is provided on the circumference of the rotating shaft 30 along its axial direction. The first bevel gear 50 is sleeved on the rotating shaft 30, and a guide ball 502 that can slide in the spiral guide groove 301 is provided on its inner side. The first transmission assembly is located in the mounting cavity 101 and is connected to two sets of take-up rollers 20. The first spring 501 connects the first bevel gear 50 and the rotating shaft 30 and is used to provide thrust for the connection between the first bevel gear 50 and the first transmission assembly. The first transmission assembly is used to convert the rotation of the first bevel gear 50 into the rotation of the two sets of take-up rollers 20, and can drive the first bevel gear 50 to slide when the take-up rollers 20 cannot rotate. The second transmission assembly is located in the mounting cavity 101 and is connected to the pressure plate 40. When the first bevel gear 50 is separated from the first transmission assembly, it is engaged with the first bevel gear 50 to convert the sliding of the first bevel gear 50 into the sliding of the pressure plate 40.

[0024] The first transmission assembly includes a second bevel gear 60, a worm gear 601, a worm wheel 602, and a linkage assembly. The second bevel gear 60 is rotatably disposed within the mounting cavity 101 and meshes with the first bevel gear 50. The worm gear 601 is coaxially disposed on the second bevel gear 60. The worm wheel 602 is coaxially disposed on one of the sets of take-up rollers 20 and meshes with the worm gear 601. The linkage assembly connects the two sets of take-up rollers 20 and drives them to rotate synchronously. Further, the linkage assembly includes a synchronous pulley 603 and a synchronous belt 604. Both sets of take-up rollers 20 are coaxially provided with synchronous pulleys 603, and the two sets of synchronous pulleys 603 are connected by the synchronous belt 604.

[0025] The second transmission assembly includes a locking block 70, a first screw 701, a rack 702, a gear 703, and a second spring 704. The locking block 70 is slidably disposed in the mounting cavity 101 along the rotating shaft 30. A locking groove 503 is provided on the circumference of the first bevel gear 50. When the first bevel gear 50 separates from the first transmission assembly, the locking block 70 is locked in the locking groove 503. A rack 702 is provided on the locking block 70. The first screw 701 is rotatably disposed on the mounting plate 10 and threadedly connected to the pressure plate 40. A gear 703 that meshes with the rack 702 is provided at the bottom end of the first screw 701. The second spring 704 connects the locking block 70 and the mounting plate 10 to provide a thrust for the locking block 70 to reset.

[0026] In the above embodiment, the first bevel gear 50 meshes with the second bevel gear 60 under the thrust of the first spring 501. Therefore, the rotation of the shaft 30 drives the worm gear 601 to rotate through the meshing of the first bevel gear 50 and the second bevel gear 60. The rotation of the worm gear 601 meshes with the worm wheel 602 to drive the take-up roller 20 to rotate. The rotation of the take-up roller 20 drives another set of take-up rollers 20 to rotate synchronously through the cooperation of the synchronous pulley 603 and the synchronous belt 604. The rotation of the two sets of take-up rollers 20 can wind up the fixing belt 201 until the fixing belt 201 can no longer be tightened, so that the take-up rollers 20 can no longer rotate, thus fixing the device. The device is easy to fix and can be easily fixed to parts of different thicknesses, improving its practicality.

[0027] After the device is fixed, continue to rotate the shaft 30. At this time, the take-up roller 20 cannot rotate, so the second bevel gear 60 cannot rotate. The first bevel gear 50 rotates and meshes with the second bevel gear 60. Through the compression of the bevel tooth inclined surface, the first bevel gear 50 can be driven to move axially along the shaft 30 under the guidance of the spiral guide groove 301. At this time, the first spring 501 is compressed and contracted. At the same time, the first bevel gear 50 and the second bevel gear 60 separate, and the locking block 70 is locked in the locking groove 503 to restrict the rotation of the first bevel gear 50. At this time, the take-up roller 20 is self-locked by the cooperation of the worm gear 602 and the worm 601, thereby maintaining the fixed state of the device.

[0028] Since the first bevel gear 50 cannot rotate due to the engagement of the locking block 70 and the locking groove 503, the rotating shaft 30 continues to rotate. This allows the first bevel gear 50 to move along the axial direction of the rotating shaft 30 via the spiral guide groove 301. The movement of the locking block 70 causes the rack 702 to move, and the second spring 704 to be compressed and contracted. The rack 702 moves and meshes with the gear 703, driving the first screw 701 to rotate. The rotation of the first screw 701 connects with the threaded connection of the pressure plate 40, which drives the pressure plate 40 to move downward and press on the bleeding point, thereby achieving the purpose of compression hemostasis. This facilitates the conversion of the rotation of the rotating shaft 30 into first driving the two sets of winding rollers 20 to rotate and fix the device, and then driving the pressure plate 40 to move downward for compression hemostasis. This makes it easier to fix the device and perform continuous operation of compression hemostasis, making it simple to operate and improving the efficiency of compression hemostasis.

[0029] Specifically, in the above embodiment, the first spring 501 is sleeved on the rotating shaft 30, and its two ends abut against the first bevel gear 50 and the end of the rotating shaft 30, respectively. The rotating shaft 30 can guide the extension and retraction of the first spring 501, thereby improving the service life of the first spring 501.

[0030] Specifically, in the above embodiment, two sets of spiral guide grooves 301 are arranged along the axial direction of the rotating shaft 30, and two sets of guide balls 502 are arranged corresponding to the two sets of spiral guide grooves 301. This improves the stability of the spiral guide grooves 301 driving the first bevel gear 50.

[0031] Please refer to the following: Figure 9Specifically, in the above embodiment, a groove 104 is provided at the bottom of the mounting cavity 101, and a slider 707 is provided at the bottom end of the snap-fit ​​block 70. The slider 707 is slidably disposed in the groove 104 along the axial direction of the rotating shaft 30. A guide rod 105 is provided at the bottom end of the mounting cavity 101, and the slider 707 is slidably sleeved on the guide rod 105. The second spring 704 is sleeved on the guide rod 105, and its two ends respectively abut against one end of the slider 707 and one end of the guide rod 105. The cooperation between the groove 104 and the slider 707 improves the sliding stability of the snap-fit ​​block 70, and the guide rod 105 guides the extension and retraction of the second spring 704, thereby improving the service life of the second spring 704.

[0032] Please see Figure 1 , Figure 2 and Figure 7 Based on the above embodiments, the second transmission assembly further includes an adjustment assembly; the adjustment assembly includes a mounting rod 705 and a second screw 706; the mounting rod 705 is slidably disposed on the mounting plate 10 along the thickness direction of the mounting plate 10 and is threadedly connected to the first screw 701, the pressure plate 40 is slidably disposed on the mounting rod 705 along the thickness direction of the mounting plate 10, and the second screw 706 is threadedly disposed on the mounting rod 705 and is rotatably connected to the pressure plate 40.

[0033] In the above embodiment, by rotating the second screw 706 to drive the pressure plate 40 to slide, the initial position of the pressure plate 40 can be adjusted, thereby increasing the pressing range of the pressure plate 40 and facilitating the individual adjustment of the pressure plate 40 on the bleeding site, so as to make adaptive adjustments according to the patient's needs and further improve the practicality of the device.

[0034] Specifically, in the above embodiment, two sets of guide shafts 401 are arranged opposite each other at the top of the pressure plate 40, and the two sets of guide shafts 401 slide along the thickness direction of the mounting plate 10 on the mounting rod 705. This ensures the stability of the sliding of the pressure plate 40.

[0035] Please see Figure 1 and Figure 8 In one embodiment, the transmission mechanism further includes a power storage component and a limiting component; the power storage component connects the rotating shaft 30 and the mounting plate 10 to store power when the rotating shaft 30 rotates, and the limiting component connects the rotating shaft 30 and the mounting plate 10 to restrict the rotating shaft 30 from reversing after storing power, and can release the restriction on the reversal of the rotating shaft 30.

[0036] Specifically, the energy storage component includes a coil spring 80; the coil spring 80 is sleeved on the rotating shaft 30, with its inner end connected to the rotating shaft 30 and its outer end connected to the mounting plate 10. The limiting assembly includes a ratchet 90, a pawl 901, and a third spring 902; the ratchet 90 is coaxially mounted on the rotating shaft 30, the pawl 901 is rotatably mounted on the mounting plate 10, and can engage or disengage from the ratchet 90; the third spring 902 connects the pawl 901 and the mounting plate 10, and is used to apply a thrust to the pawl 901 to engage with the ratchet 90.

[0037] In the above embodiment, during the process of the rotating shaft 30 driving the two sets of take-up rollers 20 to rotate and take up the fixing belt 201, and then driving the pressure plate 40 to move downward to press the bleeding opening, the coil spring 80 gradually accumulates force. After the bleeding opening is compressed and hemostasis is achieved, the rotating shaft 30 stops rotating. At this time, the pawl 901 is locked in the ratchet 90 to prevent the ratchet 90 from reversing, thereby preventing the reaction force of the coil spring 80 from driving the rotating shaft 30 to reverse. When it is necessary to disassemble the device, the third spring 902 is contracted by pressing one end of the pawl 901, and the other end of the pawl 901 is separated from the ratchet 90. At this time, the reaction force of the coil spring 80 drives the rotating shaft 30 to reverse. The reversal of the rotating shaft 30 can drive the pressure plate 40 to move upward to cancel the pressing of the bleeding opening and drive the two sets of take-up rollers 20 to rotate in opposite directions to loosen the fixing belt 201, thereby facilitating the quick disassembly of the device. The device is easy to disassemble.

[0038] Please see Figure 1 In one embodiment, an anti-slip rubber pad 103 is provided at the bottom of the mounting plate 10. The anti-slip rubber pad 103 can increase the friction between the mounting plate 10 and the bleeding site, thereby improving the stability of the device fixation and preventing the device from sliding relative to the bleeding site during subsequent use.

[0039] The specific implementation method of the above-mentioned clinical compression hemostasis device is as follows: By placing the mounting plate 10 and the fixing strap 201 together on the bleeding site and aligning the pressure plate 40 with the bleeding opening, and then rotating the shaft 30, the coil spring 80 gradually accumulates force. The rotation of the shaft 30 drives the worm gear 601 to rotate through the meshing of the first bevel gear 50 and the second bevel gear 60. The rotation of the worm gear 601 meshes with the worm wheel 602 to drive the take-up roller 20 to rotate. The rotation of the take-up roller 20 drives another set of take-up rollers 20 to rotate synchronously through the cooperation of the synchronous pulley 603 and the synchronous belt 604. The rotation of the two sets of take-up rollers 20 can wind up the fixing strap 201 until the fixing strap 201 can no longer be tightened, so that the take-up rollers 20 can no longer rotate, thus fixing the device.

[0040] After the device is fixed, continue to rotate the shaft 30. At this time, the take-up roller 20 cannot rotate, so the second bevel gear 60 cannot rotate. The first bevel gear 50 rotates and meshes with the second bevel gear 60. Through the compression of the bevel tooth inclined surface, the first bevel gear 50 can be driven to move axially along the shaft 30 under the guidance of the spiral guide groove 301. At this time, the first spring 501 is compressed and contracted. At the same time, the first bevel gear 50 and the second bevel gear 60 separate, and the locking block 70 is locked in the locking groove 503 to restrict the rotation of the first bevel gear 50. At this time, the take-up roller 20 is self-locked by the cooperation of the worm gear 602 and the worm 601, thereby maintaining the fixed state of the device.

[0041] Since the first bevel gear 50 cannot rotate due to the engagement of the locking block 70 and the locking groove 503, the rotating shaft 30 continues to rotate. This drives the first bevel gear 50 to move the locking block 70 axially along the rotating shaft 30 via the spiral guide groove 301. The movement of the locking block 70 drives the rack 702 to move, and causes the second spring 704 to be compressed and contracted. The rack 702 moves and meshes with the gear 703, driving the first screw 701 to rotate. The rotation of the first screw 701 is threadedly connected to the mounting rod 705, driving the mounting rod 705 to move the pressure plate 40 downward and press it against the bleeding point to perform compression hemostasis. At this time, the rotation of the rotating shaft 30 is stopped, and the pawl 901 is locked in the ratchet 90 to prevent the rotating shaft 30 from reversing, thus maintaining the compression hemostasis state. This facilitates the fixation of the device and the continuous operation of compression hemostasis, making it simple to operate and improving the efficiency of compression hemostasis.

[0042] During disassembly, pressing one end of the pawl 901 causes the third spring 902 to retract, separating the other end of the pawl 901 from the ratchet 90. At this time, the reaction force of the coil spring 80 drives the rotating shaft 30 to reverse. The rotating shaft 30 flips and drives the first bevel gear 50 to move in the opposite direction through the spiral guide groove 301. At this time, the reaction force of the second spring 704 keeps the locking block 70 locked in the locking groove 503, and causes the locking block 70 to drive the rack 702 to move in the opposite direction and mesh with the gear 703, driving the first screw 701 to rotate in the opposite direction. The first screw 701 rotates in the opposite direction and connects with the mounting rod 705 threadedly, driving the mounting rod 705 to drive the pressure plate 40. Moving upward cancels the pressure on the bleeding opening, and when the locking block 70 moves in the reverse direction to reset, the locking block 70 stops moving. The first bevel gear 50 moves in the reverse direction, causing the locking block 70 to exit from the locking groove 503. At the same time, under the thrust of the first spring 501, the first bevel gear 50 meshes with the second bevel gear 60 again. At this time, the rotating shaft 30 reverses and drives the worm gear 601 to rotate in the reverse direction through the meshing of the first bevel gear 50 and the second bevel gear 60. This meshes with the worm wheel 602 and drives the two sets of take-up rollers 20 to rotate in the reverse direction. The reverse rotation of the two sets of take-up rollers 20 can loosen the fixing belt 201, thereby facilitating quick disassembly of the device. The device is easy to disassemble.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
