Description

Technical Field

[0001] This application relates to the field of compression device technology, and in particular to a radial artery compression device. Background Technology

[0002] An arterial compressor, also known as an arterial compression hemostat, is a medical device used to compress and stop bleeding in arteries. It is mainly used to compress and stop bleeding at the radial artery puncture site after surgery.

[0003] The radial artery compressor includes a compression component, a connecting plate, and a bandage. The compression component is fixedly installed on the connecting plate, which has two rectangular holes at both ends. The bandage is fixedly installed on the connecting plate through the two rectangular holes. However, the bandage cannot be adjusted according to the circumference of the patient's arm. Postoperatively, the patient is prone to venous return obstruction due to compression, and cyanosis and swelling may occur after compression, causing discomfort to the patient. Utility Model Content

[0004] To avoid postoperative problems such as swelling, cyanosis, and poor venous return, this application provides a radial artery compressor.

[0005] The radial artery compressor provided in this application adopts the following technical solution:

[0006] A radial artery compressor includes a compression component, a connecting plate, and two straps. The compression component is disposed on the connecting plate, and the connecting plate has two connecting grooves at both ends. One end of each of the two straps is fixedly connected to the connecting plate through the two connecting grooves, and the other end of each strap is fixedly connected through a fixing component. Each strap has a support block provided by a sliding component.

[0007] By adopting the above technical solution, the compression component is placed on the patient's wrist through two straps. The position is adjusted according to the patient's wrist circumference and through the sliding component. After the position is determined, the position of the straps is fixed by the fixing component. The support block supports the straps, which makes it easy to adjust according to the patient's wrist circumference. At the same time, it can provide support space for the patient's postoperative venous return and reduce problems such as swelling, cyanosis and poor venous return after surgery.

[0008] Preferably, the fixing component includes a fixing frame and a fixing rod, both of which are disposed at the end of a strap. Another strap has multiple insertion holes spaced apart, and the other strap passes through the fixing frame, with the fixing rod inserted into the insertion holes.

[0009] By adopting the above technical solution, the fixing rod moves with the fixing frame according to the circumference of the patient's wrist. Multiple insertion holes are evenly spaced on the straps. After the position of the fixing frame is determined, the fixing rod is inserted into the insertion hole to fix the two straps, so that the straps are fitted and fixed on the patient's wrist without slipping.

[0010] Preferably, the sliding assembly includes a support plate, a movable plate, a limiting rod, two wedge blocks, and multiple tension springs. The support plate is nested on the strap along its circumference. Sliding grooves are formed on opposite side walls of the support plate. The two wedge blocks are slidably disposed within the two sliding grooves. The movable plate is slidably disposed within the support plate and abuts against the strap. Two wedge grooves are formed at both ends of the movable plate. The adjacent ends of the two wedge blocks are inserted into the two wedge grooves. The limiting rod is disposed on the bottom wall of the movable plate. Multiple limiting holes are spaced apart on the strap. The limiting rod is inserted into the limiting holes. The tension springs are disposed within the support plate and connect to the movable plate, driving the movable plate to move and abut against the strap.

[0011] By adopting the above technical solution, two wedge blocks slide into the support plate. The two wedge blocks drive the moving plate to move away from the support plate through the two wedge grooves. The moving plate drives the limiting rod to slide out of the limiting hole. At this time, the support plate can be moved so that the position of the support block can be adjusted on the strap. After the position of the support block is adjusted, the tension spring pulls the moving plate to move closer to the support plate. The moving plate drives the limiting rod to re-insert into the limiting hole, thus limiting the position of the support block. The position of the support block can be adjusted on the strap, making the compression device suitable for patients with different wrist circumferences.

[0012] Preferably, guide grooves are provided on both inner sidewalls of the support plate, and a guide plate is slidably disposed in the support plate within the guide groove. The guide plate is fixedly connected to the movable plate, and the tension spring is located in the guide groove, with the top end of the tension spring fixedly connected to the bottom wall of the guide plate.

[0013] By adopting the above technical solution, the tension spring pulls the moving plate through the guide plate, and the guide plate moves in the guide groove, making the movement of the moving plate more stable.

[0014] Preferably, a pressure ring is movably disposed on one of the straps, and the end of the other strap slides through the pressure ring.

[0015] By adopting the above technical solution, a pressure ring is installed on the bandage, which makes it easy to fit and nest the two unfitted parts of the bandage after determining the position according to the patient's wrist circumference, thus ensuring the effectiveness of the radial artery compressor.

[0016] Preferably, a first Velcro strap is provided on the top wall of the movable plate, and a second Velcro strap is provided on the bottom wall of the support block, wherein the first Velcro strap and the second Velcro strap are adhered to each other.

[0017] By adopting the above technical solution, the top wall of the movable plate and the bottom wall of the support block are respectively equipped with a first Velcro and a second Velcro, so that the support block can be detachably installed on the movable plate, making it convenient to replace the support block.

[0018] Preferably, each of the two wedge blocks has a limiting plate rotatably mounted at its far ends. When the limiting plate rotates to a horizontal position, the wedge blocks drive the limiting plate to slide in the groove. When the limiting plate rotates to a vertical position, the side wall of the limiting plate abuts against the outer side wall of the support plate.

[0019] By adopting the above technical solution, when the limiting plate rotates to the vertical position, one side of the limiting plate abuts against the outer wall of the support plate, preventing the support block from detaching due to accidental contact.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The compression device is placed on the patient's wrist using a bandage. The position is adjusted according to the patient's wrist circumference using a sliding component. Once the position is determined, the bandage is fixed in place using a fixing component. The support block supports the bandage, making it easy to adjust according to the patient's wrist circumference. At the same time, it can provide support space for the patient's postoperative venous return, reducing postoperative problems such as swelling, cyanosis, and poor venous return.

[0022] 2. With the help of the fixing rod, the fixing frame moves according to the circumference of the patient's wrist. Multiple holes are evenly spaced on the strap. After the position of the fixing frame is determined, the fixing rod is inserted into the holes to fix the two straps, so that the straps are fitted and fixed on the patient's wrist without slipping.

[0023] 3. By sliding two wedge blocks into the support plate, the two wedge blocks drive the moving plate away from the support plate through the two wedge grooves. The moving plate drives the limiting rod to slide out of the limiting hole. At this time, the support plate can be moved so that the position of the support block can be adjusted on the strap. After the position of the support block is adjusted, the tension spring pulls the moving plate to move closer to the support plate. The moving plate drives the limiting rod to re-insert into the limiting hole, thus limiting the position of the support block. The position of the support block can be adjusted on the strap, making the compression device suitable for patients with different wrist circumferences. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a radial artery compressor.

[0031] Reference Figure 1 A radial artery compressor includes a compression component 1, a connecting plate 2, and two straps 3. A circular compression groove is formed on the connecting plate 2 along its length, through which the compression component 1 is fixedly connected. Two rectangular connecting slots 5 are formed at both ends of the connecting plate 2. One end of each strap 3 passes through the two rectangular connecting slots 5 and is fixedly connected to the connecting plate 2. The other ends of the straps 3 are fixedly connected by a fixing component 6.

[0032] The fixing component 6 includes a fixing frame 61 and a fixing rod 62. The fixing rod 62 is located at the middle position along the length of the fixing frame 61. The fixing rod 62 is rotatably mounted on one end of the first strap 3, and the second strap 3 has a plurality of insertion holes 7 evenly spaced along its length. The second strap 3 passes through the fixing frame 61, and the fixing rod 62 passes through the insertion holes 7 of the second strap 3.

[0033] The fixing rod 62 is inserted into the insertion hole 7 to limit the position of the strap 3. A pressure ring 15 is movably fitted on the first strap 3, and the end of the second strap 3 passes through the pressure ring 15. The pressure ring 15 limits the end of the second strap 3 so that the two straps 3 can fit together.

[0034] Each bandage 3 is equipped with a sliding component 8, and a support block 9 is mounted on the sliding component 8, with the support block 9 located on the inside of the bandage 3. When the radial artery compressor is strapped to the patient's arm, the two support blocks 9 are located on both sides of the arm and provide support, reducing postoperative problems such as swelling, cyanosis, and poor venous return.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The sliding assembly 8 includes a support plate 81, a movable plate 82, a limiting rod 83, two wedge blocks 84, and four tension springs 85. The support plate 81 has a concave cross-section, and the strap 3 is located in the concave area of ​​the support plate 81. Two guide grooves 13 are formed on the two opposite inner sidewalls of the support plate 81. A guide plate 14 is slidably installed in the guide grooves 13 along the thickness direction of the support plate 81. The four tension springs 85 are located in the four guide grooves 13 respectively, and the bottom end of the tension spring 85 is fixedly connected to the support plate 81 at the bottom wall of the guide groove 13, and the top end of the tension spring 85 is fixedly connected to the bottom wall of the guide plate 14.

[0036] The movable plate 82 is slidably installed inside the support plate 81 along the thickness direction of the support plate 81. The bottom wall of the movable plate 82 abuts against the inner side wall of the strap 3. Four guide plates 14 are fixedly connected to the opposite side walls of the movable plate 82. The limiting rod 83 is fixedly installed in the middle of the bottom wall of the movable plate 82. Multiple limiting holes 12 are evenly spaced along the length of the strap 3. The limiting holes 12 are located in the middle of the width direction of the strap 3.

[0037] Four tension springs 85 pull the moving plate 82 toward the direction of the binding strap 3 via four guide plates 14. The moving plate 82 drives the limiting rod 83 to move and insert into the limiting hole 12 of the binding strap 3, thereby limiting the position of the support block 9 so that the support block 9 will not move during the support process.

[0038] Rectangular grooves 10 are provided on both opposite side walls of the support plate 81, and two wedge blocks 84 are slidably installed in the two grooves 10 respectively. Wedge grooves 11 are provided at both ends of the movable plate 82, and the two wedge blocks 84 are inserted into the two wedge grooves 11 at their closest points. Two wedge-shaped blocks 84 are rotatably mounted with limiting plates 4 at their ends. When the limiting plates 4 rotate to the same direction as the slide groove 10, they can slide into the slide groove 10. Simultaneously, pressing the two limiting plates 4 causes the wedge-shaped blocks 84 to move. The wedge-shaped blocks 84 drive the moving plate 82 to move away from the strap 3 through the wedge groove 11. The moving plate 82 drives the guide plate 14 to move in the guide groove 13. The guide plate 14 drives the tension spring 85 to be subjected to upward force, and the guide plate 14 drives the limiting rod 83 to move. At this time, the limiting rod 83 disengages from the limiting hole 12, and can then drive the support block 9 to slide through the sliding support plate 81. This allows the position of the support block 9 on the strap 3 to be adjusted, making it easier for the compressor to be suitable for different arm circumferences of the patient.

[0039] After the position of the support block 9 is adjusted, the limiting plate 4 is released. The four tension springs 85 drive the moving plate 82 to move closer to the strap 3 through the four guide plates 14. The moving plate 82 drives the limiting rod 83 to insert into the limiting hole 12, thereby limiting the position of the support block 9 again.

[0040] When the limiting plate 4 rotates to a position opposite to the slide groove 10, the side wall of the limiting plate 4 abuts against the outer side wall of the support plate 81, making the wedge block 84 unable to move, thereby fixing the limiting rod 83 in the limiting hole 12, so that the support block 9 will not be dislodged due to accidental contact.

[0041] Reference Figure 3 The top wall of the movable plate 82 is covered with a first Velcro 16, and the bottom wall of the support block 9 is covered with a second Velcro 17. The first Velcro 16 and the second Velcro 17 are bonded together, so that the support block 9 can be disassembled and replaced, making it convenient for workers to operate.

[0042] The implementation principle of a radial artery compressor according to an embodiment of this application is as follows: When the radial artery compressor is strapped to the patient's arm, the two support blocks 9 are located on both sides of the arm and provide support, reducing postoperative problems such as swelling, cyanosis, and poor venous return. When the limiting plate 4 rotates to the same direction as the slide groove 10, and the limiting plate 4 is pressed towards the limiting hole 12, the tension spring 85 drives the moving plate 82 to move upward and disengage from the slide groove 10. At this time, the moving plate 82 drives the limiting rod 83 to disengage from the limiting hole 12. The position of the support block 9 can be adjusted on the strap 3 by the support plate 81, thereby facilitating the adjustment of the position of the support block 9 according to the circumference of the patient's arm. The above are only optional embodiments of this disclosure and are not intended to limit this disclosure. For those skilled in the art, this disclosure can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
