Description

Technical Field

[0001] This invention relates to the field of pressure hemostasis technology, specifically to a pressure hemostasis device after femoral artery puncture. Background Technology

[0002] In modern medical practice, femoral artery puncture, as a key step in interventional diagnosis and treatment, is widely used in the treatment of cardiovascular diseases, neurovascular diseases, and peripheral vascular lesions. However, effective and safe hemostasis management after the procedure remains crucial for ensuring patient safety and promoting postoperative recovery. Traditional compression hemostasis methods, including manual compression and early fixed compression devices, while meeting clinical needs to some extent, have limitations that become particularly apparent in emergency medical situations, such as sudden changes in blood pressure, allergic reactions, or situations requiring immediate transport.

[0003] Specifically, manual compression relies on continuous force from medical staff and cannot be quickly relieved to deal with emergencies. Most existing compression hemostasis devices are designed to lack flexibility and immediate response capabilities. Once installed, their quick removal or adjustment becomes a problem, which may delay valuable treatment time in emergency referrals, necessary reconnection to treatment, or when patients experience discomfort. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a compression hemostasis device after femoral artery puncture, so as to solve the problem that the compression hemostasis device is difficult to remove or adjust quickly after installation in the prior art, which may delay valuable treatment time in emergency referral, necessary reconnection treatment or when the patient is uncomfortable.

[0005] This invention is achieved through the following technical solution:

[0006] A compression hemostasis device after femoral artery puncture includes a strap for wrapping around the patient's groin or waist. A hemostasis component is mounted on the strap, comprising a mounting plate connected to one end of the strap, a pressure-relieving plate positioned below the mounting plate, and a pushing component between the pressure-relieving plate and the mounting plate. The pressure-relieving plate abuts against the skin at the puncture site under the pushing force of the pushing component. A through-hole is formed in the center of the mounting plate, and the pushing component includes a sliding rod slidably connected within the through-hole, the sliding rod extending along the axis of the through-hole. Extending inwards, the lower end of the slide rod is fixedly connected to the blood pressure plate, and the upper end is fixedly connected to a screw. A threaded tube is sleeved on the screw, and a limit ring is fixedly connected to the bottom of the threaded tube. A limit assembly is installed on the mounting plate, and the limit assembly is snapped onto the limit ring. The threaded tube is rotatably connected to the mounting plate under the action of the limit assembly. A limit strip is fixedly connected inside the through hole. The limit strip extends along the length of the slide rod, and a limit groove matching the limit strip is opened on the slide rod. The limit strip is slidably connected in the limit groove.

[0007] Furthermore, the mounting plate has a hollow cavity structure, and the limiting component includes multiple C-shaped plates that are slidably connected to the cavity inside the mounting plate. The openings of the multiple C-shaped plates all face the center of the limiting ring. An elastic support component is provided between the C-shaped plates and the mounting plate, and the C-shaped plates abut against the limiting ring under the action of the elastic support component.

[0008] Furthermore, the elastic support assembly includes a plurality of first springs disposed at one end of the C-shaped plate away from the opening. The two ends of the plurality of first springs abut against the side wall of the C-shaped plate and the side wall of the cavity inside the mounting plate, respectively. In the natural state of the first springs, the plurality of C-shaped plates are engaged with the limiting ring.

[0009] Furthermore, a first groove is provided at one end of the C-shaped plate away from the opening, and a first guide rod is slidably connected in the first groove. One end of the first guide rod is fixedly connected to the side wall of the mounting plate, and the first spring is sleeved on the first guide rod.

[0010] Furthermore, the top of the mounting plate is provided with a plurality of second sliding grooves, the number of which is the same as the number of C-shaped plates. A toggle ring is slidably connected in the plurality of second sliding grooves, and the plurality of toggle rings are respectively fixedly connected to the corresponding C-shaped plates.

[0011] Furthermore, a rubber pad is provided at the bottom of the blood pressure control plate, and the top of the rubber pad is fixedly connected to the bottom of the blood pressure control plate.

[0012] Furthermore, the mounting plate is provided with a fastening assembly, which includes a first fixed rod fixedly connected to the side of the mounting plate away from the strap. A movable rod is provided on the side of the first fixed rod near the mounting plate. Both the first fixed rod and the movable rod extend perpendicular to the length direction of the strap, forming a channel through which the strap passes. The movable rod is slidably connected to the mounting plate. A plurality of second springs are provided between the movable rod and the mounting plate. The two ends of the plurality of second springs abut against the movable rod and the side wall of the mounting plate, respectively. The movable rod abuts against the strap under the thrust of the second springs.

[0013] Furthermore, a third sliding groove is provided on the side wall of the movable rod, and a second guide rod is slidably connected in the third sliding groove. One end of the second guide rod is fixedly connected to the side wall of the mounting plate, and the second spring is sleeved on the second guide rod.

[0014] Furthermore, a helical tooth is fixedly connected to the side wall of the movable rod facing the first fixed rod, with the inclined surface of the helical tooth facing downward.

[0015] Furthermore, the strap has multiple grooves that match the helical teeth, and the helical teeth are engaged in the grooves under the thrust of the second spring.

[0016] The beneficial effects of this invention are as follows:

[0017] This is a pressure hemostasis device for femoral artery puncture. The pressure plate is positioned directly over the puncture site, and a bandage is wrapped around the patient's groin or waist. When the limiting component engages with the limiting ring, the threaded tube rotates and connects to the mounting plate under the action of the limiting component. Twisting the threaded tube counterclockwise causes the screw to move the sliding rod and pressure plate downwards, allowing the pressure plate to press against the skin at the puncture site, achieving pressure hemostasis. To quickly and safely release the pressure plate, the limiting component is moved, releasing the engagement between the limiting component and the limiting ring, allowing for rapid and safe release of the pressure hemostasis device after installation. This facilitates quick removal or adjustment of the pressure hemostasis device after installation, providing valuable time for emergency transfers, reintegration of treatment when necessary, or when the patient experiences discomfort.

[0018] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0034] Please see Figure 1-8 This invention provides a technical solution: a compression hemostasis device after femoral artery puncture, comprising a strap 1 for wrapping around the patient's groin or waist, a hemostasis component on the strap 1, the hemostasis component including a mounting plate 2 connected to one end of the strap 1, a blood pressure plate 3 disposed below the mounting plate 2, and a pushing component between the blood pressure plate 3 and the mounting plate 2, the blood pressure plate 3 abutting against the patient's puncture site skin under the pushing force of the pushing component; a through hole 4 is formed in the center of the mounting plate 2, and the pushing component includes a sliding rod 5 slidably connected within the through hole 4, the sliding rod 5 moving along the through hole 4... Extending along the axial direction, the lower end of the slide rod 5 is fixedly connected to the blood pressure plate 3, and the upper end is fixedly connected to the screw rod 6. A threaded tube 7 is sleeved on the screw rod 6, and a limit ring 8 is fixedly connected to the bottom of the threaded tube 7. A limit component is installed on the mounting plate 2, and the limit component is snapped onto the limit ring 8. The threaded tube 7 is rotatably connected to the mounting plate 2 under the action of the limit component. A limit strip 9 is fixedly connected in the through hole 4. The limit strip 9 extends along the length direction of the slide rod 5, and a limit groove 10 matching the limit strip 9 is opened on the slide rod 5. The limit strip 9 is slidably connected in the limit groove 10.

[0035] In this design: the end of the strap 1 furthest from the mounting plate 2 is provided with a hook and loop fastener 25 and a rough hook and loop fastener 26, both of which are fixedly connected to the strap 1, facilitating the strap 1 to be fixed to the patient's groin or waist. The mounting plate 2 is arc-shaped, with the arc surface facing the patient's puncture site for a better fit. A limiting block 27 is provided at the connection between the slide rod 5 and the screw 6. The upper end face of the limiting block 27 is fixedly connected to the bottom of the screw 6, and the lower end face of the limiting block 27 is fixedly connected to the top of the slide rod 5, thus limiting the sliding stroke of the slide rod 5. The threaded tube 7 rotates clockwise to move the screw 6 upward, and rotates counterclockwise to move the screw 6 downward. A limiting strip 9 is fixedly connected in the through hole 4, extending along the length of the slide rod 5. A limiting groove 10 matching the limiting strip 9 is provided on the slide rod 5, and the limiting strip 9 is slidably connected in the limiting groove 10. To prevent the blood pressure plate 3 from rotating during the up-and-down sliding of the slide bar 5, thus improving patient comfort.

[0036] When in use, position the blood pressure plate 3 directly over the patient's puncture site and wrap the strap 1 around the patient's groin or waist. After adjusting the position of the strap 1, attach the hook and loop side 26 to the hook and loop side 25. Once the strap 1 is tightened, when the limiting component is engaged with the limiting ring 8, the threaded tube 7 rotates and connects to the mounting plate 2 under the action of the limiting component. At this time, twist the threaded tube 7 counterclockwise, and the screw 6 drives the slide rod 5 and the blood pressure plate 3 to move downwards, so that the blood pressure plate 3 presses against the patient's skin at the puncture site under the pushing action of the slide rod 5, thereby achieving pressure hemostasis.

[0037] When the blood pressure plate 3 needs to be released quickly and safely, the moving limiting component releases the locking relationship between the limiting component and the limiting ring 8. This allows for quick and safe release of the compression hemostasis device after installation, facilitating rapid removal or adjustment of the device and providing valuable time for emergency transfers, reconnection to treatment when necessary, or when the patient experiences discomfort.

[0038] In this embodiment: the interior of the mounting plate 2 is a cavity structure, and the limiting component includes a plurality of C-shaped plates 11 that are slidably connected to the cavity inside the mounting plate 2. The openings of the plurality of C-shaped plates 11 all face the center of the limiting ring 8. An elastic support component is provided between the C-shaped plates 11 and the mounting plate 2, and the C-shaped plates 11 abut against the limiting ring 8 under the action of the elastic support component.

[0039] In this design, there are two C-shaped plates 11, located on either side of the limiting ring 8, with their openings facing each other. The C-shaped plates 11 abut against the limiting ring 8 under the action of the elastic support assembly. This ensures that the limiting ring 8 is evenly stressed, preventing the threaded pipe 7 from tilting during rotation and causing the limiting ring 8 to disengage from the C-shaped plates 11.

[0040] In this embodiment: the elastic support assembly includes a plurality of first springs 12 disposed at one end of the C-shaped plate 11 away from the opening. The two ends of the plurality of first springs 12 respectively abut against the side wall of the C-shaped plate 11 and the side wall of the cavity inside the mounting plate 2. In the natural state of the first springs 12, the plurality of C-shaped plates 11 are engaged with the limiting ring 8.

[0041] In this design: each C-shaped block corresponds to two first springs 12. The two ends of the two first springs 12 abut against the side wall of the C-shaped plate 11 away from the opening and the side wall of the inner cavity of the mounting plate 2, respectively. In the natural state, the C-shaped plate 11 is engaged with the limiting ring 8 under the pushing force of the two first springs 12. In the compressed state, the C-shaped plate 11 has a movable gap with the limiting ring 8 under the pulling force of the two first springs 12, which facilitates the quick and safe release of the compression hemostasis device after installation.

[0042] In this embodiment: the C-shaped plate 11 has a first groove 13 at one end away from the opening, and a first guide rod 14 is slidably connected in the first groove 13. One end of the first guide rod 14 is fixedly connected to the side wall of the mounting plate 2, and the first spring 12 is sleeved on the first guide rod 14.

[0043] In this scheme: by fixing the first guide rod 14 to the side wall of the mounting plate 2, the C-shaped plate 11 slides along the length direction of the first guide rod 14, which plays a guiding role in the movement direction of the C-shaped plate 11 and the first spring 12.

[0044] In this embodiment: the top of the mounting plate 2 is provided with a plurality of second sliding grooves 15, the number of the second sliding grooves 15 is the same as the number of C-shaped plates 11, and actuating rings 16 are slidably connected in the plurality of second sliding grooves 15, and the plurality of actuating rings 16 are respectively fixedly connected to the corresponding C-shaped plates 11.

[0045] In this design: there are two second slide grooves 15, which communicate with the internal cavity of the mounting plate 2. Actuating rings 16 are fixedly connected to the C-shaped plate 11, and the rods of the actuating rings 16 are slidably connected within the second slide grooves 15. Moving the two actuating rings 16 away from the limiting ring 8 eliminates the limitation imposed by the C-shaped block on the vertical movement of the limiting ring 8, thus enabling the rapid release of the blood pressure relief plate 3.

[0046] In this embodiment: a rubber pad 17 is provided at the bottom of the blood pressure relief plate 3, and the top of the rubber pad 17 is fixedly connected to the bottom of the blood pressure relief plate 3.

[0047] In this design, a rubber pad 17 is fixedly connected to the bottom of the blood pressure plate 3. The rubber pad 17 is in contact with the patient's skin at the puncture site, making the patient more comfortable during use.

[0048] In this embodiment: a fastening assembly is provided on the mounting plate 2. The fastening assembly includes a first fixed rod 18 fixedly connected to the side of the mounting plate 2 away from the strap 1. A movable rod 19 is provided on the side of the first fixed rod 18 near the mounting plate 2. Both the first fixed rod 18 and the movable rod 19 extend perpendicular to the length direction of the strap 1. A channel for the strap 1 to pass through is formed between the first fixed rod 18 and the movable rod 19. The movable rod 19 is slidably connected to the mounting plate 2. A plurality of second springs 20 are provided between the movable rod 19 and the mounting plate 2. The two ends of the plurality of second springs 20 respectively abut against the movable rod 19 and the side wall of the mounting plate 2. The movable rod 19 abuts against the strap 1 under the pushing force of the second springs 20.

[0049] In this design: notches 28 are provided on both sides of the mounting plate 2. The first fixing rod 18 is fixedly connected to the notch 28 at the end away from the strap 1. The second fixing rod 29 is fixedly connected to the notch 28 near the strap 1. One end of the strap 1 is wrapped around the second fixing rod 29 and fixedly connected to the second fixing rod 29. The end of the strap 1 with the hook and loop fastener 25 and the loop fastener 26 fixedly connected passes through the channel between the first fixing rod 18 and the movable rod 19. After adjusting the position of the strap 1, the loop fastener 26 is pasted onto the hook and loop fastener 25, and the strap 1 is tightened.

[0050] There are two second springs 20, both ends of which abut against the movable rod 19. In their natural state, the movable rod 19 abuts against the strap 1 under the pushing force of the two second springs 20, making the strap 1 more securely installed at the patient's groin or lower back. In the compressed state, a gap exists between the movable rod 19 and the strap 1 under the pulling force of the two second springs 20, facilitating the installation and removal of the strap 1.

[0051] In this embodiment: a third sliding groove 21 is provided on the side wall of the movable rod 19, and a second guide rod 22 is slidably connected in the third sliding groove 21. One end of the second guide rod 22 is fixedly connected to the side wall of the mounting plate 2, and the second spring 20 is sleeved on the second guide rod 22.

[0052] In this design: by fixing the second guide rod 22 to the side wall of the mounting plate 2, the movable rod 19 slides along the length of the second guide rod 22, which guides the movement direction of the movable rod 19 and the second spring 20.

[0053] In this embodiment: a helical tooth 23 is fixedly connected to the side wall of the movable rod 19 facing the first fixed rod 18, and the inclined surface of the helical tooth 23 faces downward.

[0054] In this design: a helical tooth 23 is fixedly connected to the side wall of the movable rod 19 facing the first fixed rod 18, with the inclined surface of the helical tooth 23 facing downwards. The helical tooth 23 abuts against the surface of the strap 1, increasing the pressure between the movable rod 19 and the strap 1, thus further tightening the movable rod 19 against the strap 1.

[0055] In this embodiment: the strap 1 has a plurality of grooves 24 that match the helical teeth 23, and the helical teeth 23 are engaged in the grooves 24 under the pushing force of the second spring 20.

[0056] In this solution: by opening multiple grooves 24 on the strap 1 that match the helical teeth 23, the helical teeth 23 are engaged in the grooves 24 under the pushing force of the second spring 20, making the connection between the strap 1 and the movable rod 19 more secure.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
