Description

Technical Field

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

[0002] Hemostasis after radial artery puncture is a common procedure in clinical emergency care and interventional therapy, especially during endovascular interventional procedures via radial artery puncture, arterial blood gas analysis, or catheter insertion. Rapid and effective hemostasis after radial artery puncture is a crucial step in ensuring patient safety. Hemostasis not only helps prevent bleeding and reduces the risk of wound infection but also promotes patient recovery and comfort.

[0003] Existing technologies apply pressure by wrapping multiple layers of bandages, which can easily lead to operator fatigue or discomfort. Furthermore, due to insufficient experience or improper operation, the pressure can easily be too high or too low, or even the bandages may come off, affecting the hemostasis effect. In addition, nursing staff need to personally check the hemostasis on-site, which wastes time and energy. Although the existing spiral compression sleeve hemostasis device adjusts the pressure by rotating it, it is difficult to visually confirm whether the compression cylinder is accurately aligned with the puncture site.

[0004] Therefore, the present invention provides a hemostasis device after radial artery puncture. Summary of the Invention

[0005] The purpose of this invention is to provide a hemostasis device after radial artery puncture, so as to solve the problems existing in the background art.

[0006] To achieve the above-mentioned technical effects, the present invention is implemented through the following technical solution: a hemostasis device after radial artery puncture, comprising a fixing component, a pressing mechanism and a monitoring component.

[0007] Furthermore, the fixing component includes a support frame, a through groove disposed on the support frame, and a fixing component fixedly connected to the support frame; the pressing mechanism includes a pressing cylinder slidably connected to the through groove, a cover rotatably connected to the pressing cylinder, support blocks rotatably connected to both sides of the upper end of the pressing cylinder, a connecting frame fixedly connected to the support frame, a rod rotatably connected to the outer ends of the two support blocks and movably connected to the connecting frame, an arc frame fixedly connected to the support frame, and a limiting component disposed between the rod frame and the arc frame; the monitoring component includes a controller fixedly connected to the rear end of the support frame, a first pressure sensor disposed at the lower end of the pressing cylinder, a second pressure sensor fixedly connected to the bottom end of the support frame, and a motor fixedly connected to the strap assembly.

[0008] Furthermore, the connecting cover can be removed from the support frame.

[0009] Furthermore, the fixing assembly includes a roller frame fixedly connected to one side of the support frame, a connecting belt detachably connected to the roller frame rotating rod and the other side of the support frame, and the motor fixedly connected to the side end of the roller frame.

[0010] Furthermore, the compression cylinder is made of transparent hard plastic, and a hemostatic dressing is provided at the bottom of the compression cylinder.

[0011] Furthermore, a pressure rod is provided at the rear end of the rod frame, and a rotating sleeve rod is fixedly connected to the lower end of the rod frame. The rotating sleeve rod is rotatably sleeved on the connecting frame.

[0012] Furthermore, the arc frame is equipped with an arc rail.

[0013] Furthermore, the limiting component includes a slide rod fixedly connected to the side end of the pressure rod and slidably connected to the arc rail, a fixing ring threadedly connected to the slide rod, and a stop block fixedly connected to the outer end of the slide rod.

[0014] Furthermore, a connecting block is fixedly connected to the lower side of the pressing cylinder; the first pressure sensor is fixedly connected to the lower end of the connecting block.

[0015] The beneficial effects of this invention are:

[0016] This invention utilizes the lever principle, rotating the pressure rod to drive the rod frame to rotate along the connecting frame, which in turn pulls the supporting rotating block, causing the compression cylinder to slide downwards along the through groove. This allows nurses to adjust the pressure with less effort. The transparent compression cylinder allows nurses to visually observe whether the bottom of the compression cylinder is accurately aligned with the puncture site. By adjusting the limiting component, the fixation between the pressure rod and the arc rail is controlled, ensuring the stability of the compression cylinder's position. The real-time pressure display helps nurses adjust the pressure, avoiding excessive or insufficient pressure due to lack of experience or misoperation, thus improving the nurses' work efficiency.

[0052] Example 2

[0053] After the medical personnel completed the radial artery puncture, they performed hemostasis treatment at the puncture site.

[0054] The medical personnel open the protective cap 111 and then activate the controller 31 via the button module. First, the controller 31 starts the motor 35, which rotates the shaft on the roller frame 131, causing the connecting strap 13 to wind around the shaft. The tension of the connecting strap 13 is adjusted. After the second pressure sensor contacts the skin, it transmits the pressure signal to the display screen via the central processing unit. The medical personnel can confirm whether the pressure value is within the preset range based on the pressure reading on the screen. When the set pressure is reached, the motor 35 stops rotating, ensuring the support frame 11 is securely worn on the patient's wrist. The medical personnel open the cover 22 and observe through the bottom of the transparent pressure cylinder 21 to ensure the hemostatic dressing 211 at the bottom of the pressure cylinder 21 is accurately aligned with the puncture needle site. After confirming the position, the bottom of the pressure cylinder is pressed to ensure close contact between the hemostatic dressing 211 and the puncture site.

[0055] Rotate to loosen the retaining ring 272, releasing the fixed connection between the pressure rod 251 and the arc rail 261. Then, raise the pressure rod 251, causing the rod frame 25 to rotate along the connecting frame 24 via the rotating sleeve rod 252, which in turn causes the supporting rotating block 23 to pull the pressing cylinder 21 downwards along the through groove 12. This process utilizes the lever principle for effortless adjustment, gradually applying pressure to the puncture site.

[0056] Pressure sensor 32 monitors the compression pressure in real time and transmits the data to the central processor. This pressure value is displayed in real time on a screen, allowing caregivers to adjust the pressure accordingly. When the pressure reaches the set value, caregivers stop rotating the lever 25.

[0057] After pressure adjustment, the medical personnel rotate and lock the retaining ring 272, ensuring it is pressed against the side of the arc frame 26, thus fixing the pressure rod 251 to the arc rail 261 and ensuring the stability of the pressure cylinder position. Finally, the medical personnel close the cap 22 and cover the protective cap 111 to complete the fixation of the device and ensure effective hemostasis at the puncture site.

[0058] During hemostasis, the built-in wireless communication module transmits the data from the pressure sensor to the hospital's local area network in real time, ensuring timely transmission and processing of monitoring information and enabling remote monitoring.
