Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary appliances, and in particular to a hemostatic device for radial artery puncture sites after coronary artery interventional therapy. Background Art

[0002] Coronary artery intervention (CI) is currently one of the most important treatments for coronary heart disease, offering advantages such as minimal trauma and rapid recovery. Transradial artery puncture is a common approach for this treatment because the radial artery is superficial and easily accessible. It also allows for early mobilization, reducing bed rest and associated complications. Compression hemostasis is essential after puncture. Currently, medical tourniquet tape is the primary method for hemostasis. However, the low compression force of these tapes makes it difficult to effectively stop bleeding at the puncture site. Summary of the Invention

[0003] The present invention is intended to provide a hemostatic device for radial artery puncture site after coronary interventional therapy to solve the problems raised in the above background technology.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: A hemostasis device for the radial artery puncture site after coronary interventional treatment, comprising a fixed frame and a medical cotton pad, the fixed frame being connected to a connecting rod, the connecting rod being connected to a fixed block, the fixed block being slidably connected to a moving rod, the two ends of the moving rod being respectively connected to a pressing block and a limiting block, the moving rod being slidably connected to a mounting block, the mounting block being matched with the medical cotton pad, a spring being sleeved on the outer side of the moving rod, the two ends of the spring being respectively connected to the fixed block and the mounting block, the fixed frame being connected to a fixing belt, the fixing belt being connected to a child Velcro and a mother Velcro, the fixed block being connected to an adjustment structure, and the adjustment structure being used to adjust the position of the pressing block.

[0005] Preferably, the adjustment structure includes a threaded rod, the threaded rod is threadedly connected to the fixing frame, the threaded rod is rotatably connected to the fixing block, the fixing block is slidably connected to the connecting rod, and the threaded rod is connected to a handle.

[0006] Preferably, the fixing frame is connected with a silicone ring.

[0007] Preferably, the pressing block is connected with a silicone pad.

[0008] Preferably, the length of the mother Velcro is greater than the length of the child Velcro.

[0009] Preferably, the fixing belt is connected with an anti-slip strip.

[0010] Compared with the existing technology, this technical solution has the following beneficial effects: (1) This technical solution enables the medical cotton pad to fit closely to the radial artery puncture site by setting a moving rod, a pressure block and a spring, thereby achieving effective compression and hemostasis. In addition, the spring can provide a certain elastic buffer to prevent damage to the puncture site caused by excessive pressure, while ensuring continuous and stable pressure. The fixing frame can be firmly fixed on the patient's wrist through the cooperation of the fixing belt and the child Velcro and the mother Velcro, and is not easy to shift. The edge of the medical cotton pad is pressed between the mounting block and the pressure block. When the medical cotton pad needs to be replaced, it is only necessary to move the moving rod to reduce the pressure between the pressure block and the mounting block, and then the used medical cotton pad can be easily removed and replaced with a new one. The operation is simple and convenient, which is conducive to keeping the puncture site clean and reducing the risk of infection.

[0011] (2) By setting a threaded rod, the compression block can be slightly displaced in the horizontal direction, and can be fine-tuned according to the specific puncture point position of each patient to adapt to this individual difference, so as to more accurately align the radial artery puncture point, ensure the accuracy of the compression position, and improve the hemostatic effect.

[0012] (3) By setting up a silicone ring, the silicone ring is soft and elastic, and can better fit the wrist contour when in contact with the patient's skin, reducing the direct pressure and friction of the hard fixing frame on the skin, and avoiding the fixing frame causing indentations or damage to the skin, thereby reducing the patient's discomfort when wearing it and improving the wearing comfort.

[0013] (4) By providing a silicone pad, the device can better fit the curve of the human wrist and the local contour of the puncture site, ensuring uniform and tight pressure on the puncture site, thereby improving the hemostatic effect. Furthermore, when in contact with the skin, the device can reduce the pressure of the pressure block on the skin around the puncture site, thereby reducing the patient's discomfort and making the patient more comfortable when wearing the hemostatic device.

[0014] (5) By setting the mother Velcro to be longer than the child Velcro, a larger adjustment range can be provided, allowing medical staff to more flexibly adjust the strap to the appropriate tightness to ensure that the device is firmly fixed on the wrist.

[0015] (6) By setting up anti-slip strips, the friction between the fixation belt and the patient's skin can be increased. When the patient's body moves or the posture changes, the fixation belt is prevented from sliding or shifting during use, ensuring that the fixation belt always remains in the correct position and ensuring the stability of the hemostatic effect.

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1-2 The device for hemostasis of radial artery puncture site after coronary interventional treatment shown in the figure comprises a fixed frame 1 and a medical cotton pad 13. A silicone ring 9 is connected to the lower end face of the fixed frame 1. Two groups of connecting rods 5 are commonly connected to the left and right side walls of the fixed frame 1, and the two groups of connecting rods 5 are commonly slidably connected to the fixed block 2. The fixed block 2 is connected to an adjustment structure, which includes a threaded rod 17, which is threadedly connected to the side wall of the fixed frame 1, one end of the threaded rod 17 extends into the inner wall of the fixed frame 1 and is rotatably connected to the fixed block 2, and the end of the threaded rod 17 away from the fixed frame 1 is connected to a handle 16. The middle part of the fixed block 2 is longitudinally slidably connected to a moving rod 3, the top end of the moving rod 3 is connected to a limiting block 4, the bottom end of the moving rod 3 is connected to a pressure block 11, and the bottom wall of the pressure block 11 is connected to a silicone pad 12. The moving rod 3 is slidably connected to the mounting block 14, and a spring 10 is sleeved on the outside of the moving rod 3, and the two ends of the spring 10 are respectively connected to the bottom wall of the fixed block 2 and the top wall of the mounting block 14. The left and right edges of the medical pad 13 are clamped between the top wall of the pressure block 11 and the bottom wall of the mounting block 14, wrapping the pressure block 11 and the bottom of the silicone pad 12. The left and right sides of the fixing frame 1 are connected to fixing straps 6. The two sets of fixing straps 6 are connected to a child Velcro 7 and a mother Velcro 15, respectively. The mother Velcro 15 is longer than the child Velcro 7. The side of the fixing strap 6 that contacts the patient's skin is connected to an anti-slip strip 8.

[0018] The fixing frame 1 is wrapped around the patient's wrist through the fixing belt 6, and the sub-velcro 7 and the main Velcro 15 are adhered to each other to fix the fixing belt 6, so that the entire hemostatic device is fixed on the wrist. The anti-slip strip 8 increases the friction between the fixing belt 6 and the skin, preventing the fixing belt 6 from sliding or shifting when the patient moves, ensuring the stability of the hemostatic device. The silicone ring 9 enhances the fit between the fixing frame 1 and the wrist, further improving the fixing effect. At this time, the medical cotton pad 13 is pressed on the radial artery puncture site, exerting an upward force on the pressure block 11, causing the spring 10 to compress, and the elastic force reacts on the pressure block 11, causing the medical cotton pad 13 to squeeze the radial artery puncture site. Turn the handle 16 on the threaded rod 17. Since the threaded rod 17 is threadedly connected to the side wall of the fixing frame 1, the rotation will drive the threaded rod 17 to move axially. The threaded rod 17 pushes the fixed block 2, causing the fixed block 2 to slide horizontally on the connecting rod 5, thereby driving the movable rod 3, the pressing block 11 and the mounting block 14 to move together, thereby achieving fine-tuning of the position of the medical cotton pad 13 so that the medical cotton pad 13 can be located just above the radial artery puncture site.

[0019] The specific implementation process is as follows: When in use, select a medical cotton pad 13 of appropriate size and place its left and right edges between the top wall of the pressing block 11 and the bottom wall of the mounting block 14, so that the medical cotton pad 13 wraps the pressing block 11 and the bottom of the silicone pad 12. Fit the silicone ring 9 on the fixing frame 1 near the radial artery puncture site on the patient's wrist, so that the medical cotton pad 13 is aligned with the puncture point. Then wrap the fixing belt 6 around the wrist, and adjust the pasting position of the sub-velcro 7 and the main Velcro 15 according to the thickness of the patient's wrist to ensure that the fixing belt 6 is appropriately tight. If the medical cotton pad 13 is not aligned with the puncture point, turn the handle 16 on the threaded rod 17 and fine-tune the position of the pressing block 11 according to the position of the puncture point so that the medical cotton pad 13 is aligned with the puncture point. The medical cotton pad 13 presses the puncture point to stop bleeding. When the hemostasis time is reached and the puncture site is in good hemostasis, the medical staff unties the child Velcro 7 and the mother Velcro 15, carefully removes the fixing belt 6 and the fixing frame 1, and then takes out the used medical cotton pad 13 to perform subsequent cleaning and care for the puncture site.
