Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a pressure hemostasis device for femoral artery puncture in interventional procedures. Background Technology

[0002] Femoral artery puncture is a common vascular access method for various interventional surgeries. Postoperatively, the mainstream clinical approach is to wrap gauze and elastic bandages in a figure-eight pattern around the patient's groin, thigh, and waist in multiple layers to apply pressure. This needs to be continuously fixed for 24 hours and is a basic clinical hemostasis method.

[0003] The traditional method of applying pressure relies entirely on the experience of medical staff, making it difficult to control precisely. If the pressure is too loose, it can easily cause bleeding at the puncture site; if it is too tight, it can cause discomfort such as local swelling, pain, and numbness in patients. Often, the pressure needs to be removed and re-bandaged, increasing the workload of medical staff and the risk of secondary bleeding at the puncture site. At the same time, applying pressure indiscriminately over a wide area can easily cause local skin ischemia in obese patients, leading to device-related skin damage. Furthermore, it cannot achieve precise local pressure application at the puncture site or maintain stable and controllable pressure, making it difficult to balance hemostasis and patient comfort.

[0004] Based on this, a pressure hemostasis device for femoral artery puncture in interventional procedures is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure hemostasis device for femoral artery puncture in interventional procedures in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pressure hemostasis device for femoral artery puncture in interventional radiology includes a silicone band and an elastic band. A connecting platform is fixedly connected to the center of the silicone band and extends through the silicone band. A square storage groove is provided on the side of the connecting platform that abuts against the patient's skin. A cannula is connected to the side of the connecting platform away from the patient's skin. A screw is installed inside the cannula, and a pressure plate is rotatably connected to the lower end of the screw. A hemostatic patch is connected to one side of the pressure plate and abuts against the patient's puncture site. A knob is connected to the upper end of the screw. A switching mechanism is provided on the outside of the cannula to cooperate with the screw to achieve rapid positioning and pressure hemostasis at the patient's puncture site, and then precisely adjust the pressure of the pressure plate.

[0008] Preferably, both ends of the silicone strip are provided with connecting grooves for connecting one end of the elastic strap, and the other end of the elastic strap is connected with a Velcro that can cooperate with each other.

[0009] Preferably, a positioning pad is connected to the silicone strip in a direction perpendicular to the silicone strip. When the hemostatic device is connected to the patient, one side of the positioning pad is in contact with the patient's skin. On the positioning pad, anti-slip strips are connected at equal intervals on the side in contact with the patient's skin. One end of the positioning pad is connected to a limiting member for restricting the rotation of the pressure plate, and the limiting member is symmetrically connected to both sides of the pressure plate.

[0010] Preferably, the lower end of the screw is connected to a rotating buckle, and the side of the pressure plate away from the hemostatic patch is connected to a rotating seat. The rotating buckle has a "T" shaped cross section, and the rotating seat is rotatably connected to the rotating buckle.

[0011] Preferably, the limiting component includes a limiting block, and a slot is provided on the silicone strip for the limiting block to be inserted. The upper and lower ends of the limiting block are respectively connected to a limiting end and a deflection shaft, and one end of the positioning pad is rotatably connected to the deflection shaft.

[0012] Preferably, the switching mechanism includes a semi-circular tube, which is rotatably connected to the connecting platform. Two sets of semi-circular tubes are provided. After the two sets of semi-circular tubes are rotatably connected, they are set on the upper end of the sleeve. The inner and outer sides of the semi-circular tube are respectively provided with internal threads and external threads, and the external threads are set at the end near the sleeve. A threaded tube that cooperates with the external threads is rotatably connected to the outer side of the sleeve.

[0013] Preferably, a connecting frame is connected to the outside of the semi-circular tube, a rotating shaft is connected to one end of the connecting frame, and a hinged end for rotating the rotating shaft is fixedly connected to the connecting platform.

[0014] Preferably, the upper end of the sleeve is connected to a limiting ring one, and the first end of the threaded pipe is connected to a limiting ring two.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This application adopts a combination structure of screw and switching mechanism to achieve precise local pressure application and flexible pressure control at the puncture point. It can meet the high pressure hemostasis requirements in the early stage of coagulation and can quickly depressurize after coagulation. It solves the problem that the pressure of the traditional figure-of-eight bandage method depends on manual experience and cannot be accurately controlled, and avoids patient discomfort caused by excessively loose or excessively tight bandage.

[0016] 2. This application achieves localized fixation of the device to the patient's leg by using a positioning pad with anti-slip strips and an elastic bandage, eliminating the need for extensive wrapping around the waist. This solves the problem of skin ischemia caused by indiscriminate pressure application in traditional bandaging methods, reduces device-related skin damage, improves patient comfort, and reduces the workload of medical staff.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 The present invention provides a technical solution: A pressure hemostasis device for femoral artery puncture in interventional radiology includes a silicone band 1 and an elastic band 3. A connecting platform 6 is fixedly connected to the center of the silicone band 1. The connecting platform 6 is square in structure and is connected to the silicone band 1. A square receiving groove 18 is provided on the side of the connecting platform 6 that abuts against the patient's skin. The receiving groove 18 fits into the pressure plate 17. A sleeve 14 is connected to the side of the connecting platform 6 away from the patient's skin. A screw 13 is installed inside the sleeve 14. The sleeve 14 is fitted over the outside of the screw 13, and the screw 13 passes through the sleeve. On the connecting platform 6, a pressure plate 17 is rotatably connected to the lower end of the screw 13. A hemostatic patch 19 is connected to one side of the pressure plate 17 and abuts against the patient's puncture site. A knob 12 is connected to the upper end of the screw 13. By rotating the knob 12, the screw 13 can be rotated synchronously. The outside of the sleeve 14 is provided with a mechanism for cooperating with the screw 13 to achieve quick positioning and pressure hemostasis at the patient's puncture site. Then, the pressure of the pressure plate 17 can be precisely adjusted. Quick positioning can reduce adjustment time and improve the connection efficiency of the pressure hemostasis device.

[0021] Specifically, such as Figure 2 and Figure 3 As shown, both ends of the silicone band 1 are provided with connecting grooves 2 for connecting one end of the elastic band 3. The other end of the elastic band 3 is connected with Velcro 4 that can cooperate with each other. The elastic band 3 has an elastic connection structure, which can improve the patient's comfort. The structure of Velcro 4 improves the connection convenience and ensures that the pressure hemostasis device can be quickly connected after the patient's puncture surgery.

[0022] Specifically, such as Figure 2 As shown, a positioning pad 5 is connected to the silicone strip 1 in a direction perpendicular to the silicone strip 1. When the hemostatic device is connected to the patient, one side of the positioning pad 5 is in contact with the patient's skin. On the side of the positioning pad 5 that is in contact with the patient's skin, there are anti-slip strips 7 that are set at equal intervals. By setting the anti-slip strips 7, the structural stability of the positioning pad 5 when it is connected is improved, and slippage is avoided. The positioning pad 5, by being set perpendicular to the silicone strip 1, achieves all-round limitation of the pressure hemostatic device, ensuring the stability of the device connection position. After the hemostatic device is worn, the patient can wear close-fitting clothing on the legs. With the help of the wrapping force of the close-fitting clothing, the positioning pad 5 is tightly pressed against the leg skin to prevent the device from shifting. One end of the positioning pad 5 is connected to a limiting member for restricting the rotation of the pressure plate 17. The limiting members are symmetrically connected to both sides of the pressure plate 17. By setting the limiting members, the rotation of the pressure plate 17 can be prevented. The pressure plate 17 only rotates when it is being adjusted. At this time, one side of the pressure plate 17 is pressed against the skin of the patient's leg. Excessive rotation will cause the skin to twist and pull, causing discomfort.

[0023] Specifically, such as Figure 9As shown, a rotating buckle 26 is connected to the lower end of the screw 13, and a rotating seat 27 is connected to the side of the pressure plate 17 away from the hemostatic patch 19. The rotating buckle 26 has a "T" shaped cross section, and the rotating seat 27 is rotatably connected to the rotating buckle 26. The rotating buckle 26 and the rotating seat 27 can be stably connected. The two structures can only rotate relative to each other and cannot be separated, which ensures that the pressure of the pressure plate 17 on the puncture position on the side of the rotating seat 27 can be changed without causing the pressure plate 17 to rotate excessively.

[0024] Specifically, such as Figure 2 and Figure 4 As shown, the limiting component includes a limiting block 9. A slot 8 is provided on the silicone strip 1 for the limiting block 9 to be inserted. The upper and lower ends of the limiting block 9 are respectively connected to a limiting end 10 and a deflection shaft 11. The limiting end 10 is set to prevent the limiting block 9 from separating from the slot 8. One end of the positioning pad 5 is rotatably connected to the deflection shaft 11. There are two limiting blocks 9. When the limiting blocks 9 limit the rotation of the pressure plate 17, the two limiting blocks 9 are held in parallel on both sides of the pressure plate 17.

[0025] Specifically, such as Figure 8 As shown, the switching mechanism includes a semi-circular tube 21, which is rotatably connected to the connecting platform 6. Two sets of semi-circular tubes 21 are provided. After the two sets of semi-circular tubes 21 are rotatably connected, they are set on the upper end of the sleeve 14. The inner and outer sides of the semi-circular tube 21 are respectively provided with internal threads 23 and external threads 24. The external threads 24 are set at the end near the sleeve 14. The internal threads 23 are axially connected to the semi-circular tube 21, but the external threads 24 are only set at the end area of ​​one end of the semi-circular tube 21. The outer side of the sleeve 14 is rotatably connected with a threaded tube 25 that mates with the external threads 24. Due to the combined structure of the semi-circular tubes 21, the external threads 24 and internal threads 23 only present a complete thread structure after the two semi-circular tubes 21 are connected to each other. The complete internal threads 23 can mate with the screw 13, and the complete external threads 24 can mate with the threaded tube 25.

[0026] Specifically, such as Figure 7 and Figure 8 As shown, a connecting frame 20 is connected to the outside of the semi-circular tube 21. A rotating shaft 22 is connected to one end of the connecting frame 20. A hinge end 16 for rotating the rotating shaft 22 is fixedly connected to the connecting platform 6. By setting the hinge end 16 to cooperate with the rotating shaft 22, the stability of the rotating connection of the connecting frame 20 can be improved.

[0027] Specifically, such as Figure 9 As shown, the upper end of the sleeve 14 is connected to a limiting ring 15, and one end of the threaded tube 25 is connected to a limiting ring 28. By setting the limiting ring 15 and the limiting ring 28, the separation between the threaded tube 25 and the sleeve 14 can be avoided, thus ensuring the stability of the connection of the threaded tube 25.

[0028] In summary, the femoral artery puncture post-procedure compression hemostasis device provided in this embodiment addresses the challenges of femoral artery puncture in interventional procedures. As a major blood vessel, the femoral artery is prone to complications such as bleeding and hematoma after puncture. The core function of the compression hemostasis device is to replace manual continuous compression, achieving precise, stable, and controllable hemostasis while reducing the workload of medical staff and improving patient comfort.

[0029] After the interventional femoral artery puncture, the silicone band 1 is removed, and the hemostatic patch 19 connected to the silicone band 1 is placed against the puncture site. Then, the silicone band 1 is fitted to the contour of the patient's leg. The silicone band 1 is a flexible and malleable plate with an internal memory metal skeleton and an outer layer of silicone material. When it comes into contact with the patient's skin, it can automatically conform to the contour of the leg, increasing the pressure contact area. Then, it is connected to the patient's leg by the elastic band 3, thereby stabilizing the connection of the silicone band 1. Before the silicone band 1 is connected, the medical staff need to continuously press the screw 13 to ensure that the hemostatic patch 19 on the pressure plate 17 is stably attached to the puncture site.

[0030] After the silicone tape 1 is connected, press the screw 13 further to increase the pressing pressure and ensure that the hemostatic patch 19 can stop bleeding by abutting the high pressure in the early stage of coagulation. Then deflect the connecting bracket 20 so that the two semi-circular tubes 21 are connected to each other to form a complete tube structure, and ensure that the internal thread 23 in the semi-circular tube 21 is engaged with the thread on the screw 13. Pull up the threaded tube 25 and rotate it so that it is rotated and connected to the outside of the semi-circular tube 21. At this time, the threaded tube 25 is connected to the external thread 24 on the outside of the semi-circular tube 21, and the threaded tube 25 is used to limit the connection state between the semi-circular tubes 21.

[0031] Simultaneously press down on the two limiting blocks 9, so that the end of the limiting block 9 away from the deflection axis 11 abuts against the skin of the patient's leg. Then rotate the knob 12. When the knob 12 rotates, it can further press the pressure plate 17 towards the patient's puncture site. During this process, the pressure plate 17 moves a small distance and the knob 12 has high adjustment precision. When pressing, it is necessary to ask the patient if there is any discomfort. If the patient is uncomfortable, the pressure adjustment should be stopped immediately. When the knob 12 drives the screw 13 to rotate, the lower end of the screw 13 can easily drive the pressure plate 17 to rotate, causing the skin at the puncture site to twist and pull. Pressing down on the limiting blocks 9 on both sides of the pressure plate 17 can limit the excessive rotation of the pressure plate 17 and avoid causing the skin to twist and pull when adjusting the pressure, which would cause discomfort to the patient.

[0032] After the pressure plate 17 is finely adjusted, the limiting block 9 is released and the positioning pad 5 is unfolded, so that the anti-slip strip 7 side of the positioning pad 5 abuts against the patient's leg skin. The positioning pad 5 increases the contact area and prevents the position of the hemostatic device from shifting. The positioning pad 5 is positioned perpendicular to the silicone strip 1, which further ensures the stability of the overall structural connection.

[0033] When initial clotting is completed at the puncture site, decompression is required to avoid excessive pressure that could damage blood vessels. At this time, simply rotate the threaded tube 25 to remove the restriction on the semi-circular tube 21. Then, under the elasticity of the skin, the pressure plate 17 is retracted into the storage groove 18, while the hemostatic patch 19 remains against the puncture site.

[0034] The compression device allows for initial coarse adjustment, quickly pressing the patient's puncture site, followed by fine adjustment of the compression pressure to ensure high-pressure hemostasis in the early stages of clotting. Once clotting is complete, the high-intensity compression can be quickly released without the need for inefficient adjustment by rotating the screw 13. This ensures hemostasis while reducing the risk of vascular complications caused by excessive compression. Furthermore, the elastic band 3 and silicone band 1 achieve an adaptive fit to the patient's leg, making it easy to put on and take off. The added positioning pad 5 also prevents structural displacement caused by the patient's movement while wearing the device, ensuring hemostasis stability.

[0035] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
