Description

Technical Field

[0001] This utility model relates to the field of hemostasis technology, and more specifically, to a pressure hemostasis device for cardiology nursing. Background Technology

[0002] When performing coronary angiography in cardiology, a puncture sheath is inserted into the radial artery in the wrist. The pressure hemostatic device is an auxiliary device used to compress the puncture site and prevent bleeding after interventional procedures via the radial artery (such as coronary angiography or stent implantation).

[0003] Chinese Patent Publication No. CN222130195U discloses a radial artery hemostatic compressor. This design, through the cooperation of a rotating head and a movable rod structure, not only allows for the rotation and adjustment of the movable rod's reciprocating motion along the axial direction, but also enables contact compression of the skin on the arm through its enlarged end. This results in a simple and convenient structure. Furthermore, the built-in compression rod and air chamber structure allow for multiple compression force determinations using non-electronic principles, providing users with adjustments based on the initial compression force ratio. This facilitates subsequent adjustments, avoiding reliance on user experience for rotational adjustments, thus improving accuracy and convenience. Simultaneously, it meets the high-frequency sterilization requirements of this type of medical device.

[0004] Because the puncture sheath is thicker than a regular needle and the puncture site is the radial artery, the puncture site will bleed rapidly when the puncture sheath is pulled out. The hemostatic device described above moves the compression device to squeeze the puncture site by rotating it. However, the rotation operation needs to be repeated several times, which prolongs the operation time and is not conducive to rapid compression hemostasis after the puncture sheath is pulled out.

[0005] Therefore, a pressure-based hemostasis device for cardiology nursing is proposed to address the above problems. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1 - Figure 8 A pressure hemostasis device for cardiology nursing includes: a mounting strap 2, a compression component 6, an inflation component 7, and an air tube 8. The mounting strap 2 is wrapped around the wrist and close to the skin. The compression component 6 is installed inside the mounting strap 2 and includes an air bladder 61 and an air bladder 62, which are fixedly connected and internally connected. The inflation component 7 includes a cylinder 71 and a piston 73, which is slidably connected to the inner wall of the cylinder 71. The inflation component 7 and the air bladder 62 are connected through the air tube 8. Both the air bladder 61 and the air bladder 62 are inflated and expanded by the piston 73 moving within the cylinder 71, compressing the wound to stop bleeding.

[0040] The device in this solution is mainly used to quickly apply pressure to the puncture site for hemostasis after the puncture sheath is removed following coronary angiography in the cardiology department. The connecting strap 1, the mounting strap 2, and the elastic band 4 are connected together to form a wristband that can be worn on the wrist. An inflation component 7 is installed at the outer end of the mounting strap 2, and a compression component 6 is installed on the inner side of the mounting strap 2 near the middle. The inflation component 7 is mainly used to inflate the compression component 6, which is used to apply pressure to the puncture site for hemostasis. The compression component 6 is connected to the inflation component 7, which is attached to the outside of the mounting strap 2, via an air tube 8. By pressing the thumb against the pressing block 78, the drive rod 77 drives the piston 73 to squeeze the air inside the cylinder 71 into the compression component 6, thereby allowing the compression component 6 to expand rapidly and apply pressure to the puncture site for hemostasis. This reduces the number of steps and time required for the operation and improves the efficiency of medical staff.

[0041] Please see Figure 1 and Figure 2 It also includes: an elastic band 4 and two connecting bands 1. The outer end of the elastic band 4 is provided with Velcro so that the outer surface is folded and glued together. The two connecting bands 1 are respectively installed at both ends of the mounting band 2. One end of each of the two connecting bands 1 is equipped with a buckle 3. One end of the elastic band 4 is installed on one of the buckles 3 and the elastic band 4 passes through the other buckle 3. Two anti-slip pads 5 are installed on the inner side of the mounting band 2.

[0042] The mounting strap 2 in this design is made of plastic, allowing the inflation component 7 and compression component 6 to be mounted on it. The mounting strap 2 also enhances structural strength and prevents deformation after prolonged use. Connecting straps 1 are fixed to both ends of the mounting strap 2, and these straps can be glued to the mounting strap 2. The connecting straps 1 are made of fabric to help the mounting strap 2 be worn on the wrist. A buckle 3 is mounted on the other end of the connecting strap 1. The buckle 3 can be made of plastic to reduce its weight. On one of the buckles 3... The elastic band 4 is installed, and the other end of the elastic band 4 is folded through another loop 3. Velcro is sewn onto the outer end of the elastic band 4, which allows the elastic band 4 to be folded and glued together. When using it, first put the installation strap 2 on the wrist, then align the compression component 6 with the puncture point, pass the elastic band 4 through the loop 3 and tighten the elastic band 4, then fold the elastic band 4 together to complete the fixation. Then, after pulling out the puncture sheath, quickly press the inflation component 7 to make the compression component 6 compress the puncture point to stop the bleeding.

[0043] Two anti-slip pads 5 are installed on the inside of the installation band 2. The anti-slip pads 5 are made of silicone. When the installation band 2 is worn on the wrist, the anti-slip pads 5 will fit tightly against the skin, which can increase its friction and make the pressure component 6 less likely to move or deviate from the puncture point, thus improving the stability of wearing.

[0044] Please see Figure 4 The connection between airbag 1 61 and airbag 2 62 is recessed inward, and an installation pad 9 is fixedly installed on the outer end of airbag 2 62. The installation pad 9 is installed on the inner side of the installation belt 2.

[0045] The compression component 6 in this design is mainly used to compress the puncture point. Airbag 1 61 and Airbag 2 62 are fixedly connected and internally interconnected. An mounting pad 9 is fixed to the outer end of Airbag 2 62, and the mounting pad 9 is fixed to the inner side of the mounting belt 2. The compression component 6 is mounted on the mounting belt 2 via the mounting pad 9. One end of the air tube 8 is connected to Airbag 2 62, and the other end of the air tube 8 passes through the mounting belt 2 and connects to the cylinder 71, allowing the cylinder 71 to communicate with the interior of Airbag 2 62. Both Airbag 2 62 and Airbag 1 61 are annular, so the connection between Airbag 1 61 and Airbag 2 62 is a concave annular arrangement. This concave annular arrangement guides the expansion of Airbag 1 61 and Airbag 2 62. When Airbag 1 61 and Airbag 2 62 are not inflated and are compressed, they fold vertically together. When inflated, they expand rapidly vertically, increasing the vertical expansion distance and providing greater pressure to the puncture point.

[0046] It is worth mentioning that when using it, gauze should be placed at the bottom of the airbag 61 to prevent the airbag 61 from directly contacting the skin.

[0047] Please see Figure 5 - Figure 8 An installation block 10 is fixedly installed on the outer end of the cylinder 71. The cylinder 71 is installed on the outside of the installation belt 2 through the installation block 10. Two extension blocks 72 are fixedly installed on the outer end of the cylinder 71. A drive rod 77 is provided on the top of the piston 73.

[0048] The drive rod 77 includes piston rod 1 771, piston rod 2 772 and base 775. Piston rod 1 771 and piston rod 2 772 are both fixedly installed on the top of base 775, and a spring piece 774 is provided in the gap between piston rod 1 771 and piston rod 2 772. Base 775 is fixedly installed on the top of piston 73.

[0049] Both piston rod 771 and piston rod 772 have equidistantly distributed limiting grooves 710 at their outer ends. A fixing ring 75 is fixedly installed on the top of the cylinder 71. Two sets of limiting teeth 76 that are adapted to the limiting grooves 710 are fixedly installed on the inner side of the fixing ring 75. The tops of the limiting grooves 710 and the limiting teeth 76 are inclined, and the bottoms of the limiting grooves 710 and the limiting teeth 76 are flat.

[0050] The inflation assembly 7 also includes a pressing block 78, with sliders 773 fixedly installed on the top of piston rod 1 771 and piston rod 2 772. The bottom of the pressing block 78 has a groove 74, and the slider 773 is adapted to the groove 74. The inner side of piston rod 1 771 has a movable groove 776, and a spring piece 774 is installed inside the movable groove 776. The outer end of the spring piece 774 protrudes and abuts against piston rod 2 772. Pressure plates 79 are rotatably installed at both ends of the pressing block 78.

[0051] The inflation component 7 in this scheme is mainly used to inflate the compression component 6. The mounting block 10 is fixed to the outer end of the cylinder 71, and the cylinder 71 is fixed to the outer end of the mounting belt 2 by the mounting block 10.

[0052] A piston 73 is slidably mounted inside the cylinder 71. A drive rod 77 is mounted on the top of the piston 73, extending through the top of the cylinder 71 to the outside. The drive rod 77 is mainly composed of piston rod one 771 and piston rod two 772. Both piston rod one 771 and piston rod two 772 are fixed to a base 775, which in turn is fixed to the piston 73. A gap is provided between piston rod one 771 and piston rod two 772. Both are made of plastic. Equally spaced limiting grooves 710 are provided on piston rod one 771 and piston rod two 772. A fixing ring 75 is fixed to the top of the cylinder 71. Two sets of limiting teeth 76 are fixed inside the fixing ring 75. Each set of limiting teeth 76 consists of multiple... The device consists of a limiting groove 710 and a limiting tooth 76, which are shaped to match each other. The upper part of the limiting groove 710 and the limiting tooth 76 are both set as inclined surfaces, while the bottom part is set as a flat surface. With this configuration, when the piston rod 771 and the piston rod 772 move downward, the inclined surface inside the limiting groove 710 abuts against the inclined surface of the limiting tooth 76, which will compress the piston rod 771 and the piston rod 772. At this time, the piston rod 771 and the piston rod 772 will move closer to each other, so that the limiting groove 710 passes over the limiting tooth 76, thereby allowing the piston rod 771 and the piston rod 772 to move downward. When the piston rod 771 and the piston rod 772 move upward, the two flat surfaces abut against each other and are locked together, so that they can only move in one direction.

[0053] A movable groove 776 is formed on the inner side of piston rod 771, and spring 774 is installed on the inner side of movable groove 776. Spring 774 is made of thin metal sheet. When piston rod 771 and piston rod 772 approach each other, piston rod 772 abuts against the outer end protrusion of spring 774, which will squeeze spring 774, causing its two ends to slide inside movable groove 776. Spring 774 is flattened. When the limiting groove 710 passes the limiting tooth 76, the elastic force of spring 774 will reset it, so that the limiting tooth 76 can tightly abut against the inner side of limiting groove 710 to form a limit.

[0054] Slider 773 is fixed to the top of piston rod 1 771 and piston rod 2 772, while a groove 74 is opened on the inner side of the pressing block 78. The slider 773 is slidably connected to the groove 74, so that the pressing block 78 can be installed on the top of piston rod 1 771 and piston rod 2 772. At the same time, when piston rod 1 771 and piston rod 2 772 approach each other, they can drive the slider 773 to move inside the groove 74.

[0055] Pressure plates 79 are rotatably mounted on both ends of the pressing block 78. The outer end of the pressure plate 79 has an outward protrusion. When it is necessary to release air from the pressing assembly 6, the two pressure plates 79 can be pinched by hand, so that the outward protrusion of the pressure plate 79 abuts against the piston rod 771 and the piston rod 772. Then, force is applied to bring the piston rod 771 and the piston rod 772 closer to each other. At this time, the limiting groove 710 can be disengaged from the limiting tooth 76, so that the drive rod 77 can move upward to release air from the pressing assembly 6.

[0056] Two extension blocks 72 are fixed to the outer end of the cylinder 71. The upper limit groove 710 of the drive rod 77 engages with the limiting teeth 76 on the fixing ring 75. When pressure hemostasis is required, simply hook the two extension blocks 72 with your index and middle fingers, and then press the pressing block 78 with your thumb. This will cause the piston 73 to deliver air to the pressure assembly 6 through the drive rod 77, causing the pressure assembly 6 to expand. Compared with using threaded rotation, this simplifies the operation steps, saves operation time, improves efficiency, and facilitates rapid pressure hemostasis after the puncture sheath is removed.

[0057] Working principle: When using this device, firstly, the installation strap 2 needs to be worn on the wrist so that the compression component 6 presses on the puncture point and the puncture sheath. Then, the elastic band 4 is tightened to complete the fixation. After the puncture sheath is pulled out, the compression block 78 is pressed quickly. The piston 73 is driven by the drive rod 77 to supply air to the compression component 6. After inflation, the compression component 6 can quickly expand vertically to compress the puncture point to form hemostasis. At the same time, the plane on the inner side of the limiting groove 710 abuts against the plane of the limiting tooth 76 to form a limit, and the piston 73 cannot move upward automatically.
