Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a device for fixing a radial artery puncture site after PCI surgery for coronary heart disease. Background Art

[0002] PCI, or percutaneous coronary intervention (PCI), is a treatment method that uses cardiac catheterization to clear narrowed or even occluded coronary arteries, thereby improving myocardial blood flow. It is currently one of the most important treatments for coronary artery disease, particularly acute myocardial infarction and severe angina. PCI is necessary because when coronary artery stenosis or blockage occurs due to coronary atherosclerosis, myocardial blood flow can be severely impaired. Mild cases may experience angina symptoms such as paroxysmal chest pain and tightness, which can affect patients' daily lives, reduce their exercise tolerance, and limit their range of motion.

[0003] After PCI for coronary artery disease, compression is generally performed on the radial artery puncture site. This is primarily to prevent bleeding. Due to high arterial pressure, lack of compression can easily lead to bleeding and hematoma. Compression promotes wound healing and prevents localized thrombosis, which can be caused by abnormal blood flow due to bleeding. It also alleviates pain and discomfort caused by bleeding and hematoma, ensuring safe and smooth follow-up treatment.

[0004] Currently, there are corresponding radial artery puncture site pressing devices for pressing the puncture site. However, after pressing, the patient's wrist can move within a certain range. If the patient moves within a small or large range, the pressing effect of the pressing device on the puncture site will be reduced, and the pressing effect will not meet the required pressure. To a certain extent, there are still defects.

[0005] Therefore, a device for fixing the radial artery puncture site after PCI for coronary heart disease is needed to solve the above technical problems. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention discloses a radial artery puncture site fixation device after PCI surgery for coronary heart disease. The device can be used in conjunction with a compression device.

DETAILED DESCRIPTION

[0025] Example 1

[0026] A device for fixing the radial artery puncture site after PCI surgery for coronary heart disease comprises: an arm support plate 1, a support plate 312, a clamping assembly 3, and a hand-held assembly 4; the arm support plate 1 is an arc-shaped structure, the support plate 312 is fixedly mounted on the inner upper end of the arm support plate 1, the clamping assembly 3 is fixedly mounted on the front end of the side wall of the arm support plate 1, and the hand-held assembly 4 is fixedly mounted on the front end of the arm support plate 1; the clamping assembly 3 is fixedly mounted on the front end of the side wall of the arm support plate 1 for fixing the patient's wrist; the hand-held assembly 4 is fixedly mounted on the front end for easy holding by the patient. When the patient uses the device, he places his arm on the arm support plate 1, fixes his wrist by operating the clamping assembly 3, and then holds the hand-held assembly 4 so that the device is tightly combined with the patient's arm. Several fixing straps 11 are fixedly mounted on the side wall of the arm support plate 1; the entire device can be fixed to the hand by the fixing straps 11.

[0027] The clamping assembly 3 includes a support plate 312, a fixed cover 32, a transmission rack 15, a gear 331, and a clamping plate 34. The support plate 312 is fixedly mounted on the side wall of the arm support plate 1, providing a mounting base for components such as the gear 331. The gear 331 is movably mounted on the upper end of the support plate 312, and the outside is isolated by the fixed cover 32 to prevent external factors from interfering with the rotation of the gear 331. The transmission rod 33 is fixedly mounted on the gear 331, and the clamping plate 34 is fixedly mounted on the upper end of the transmission rod 33. The transmission rack 15 is movably mounted on the square groove 14 symmetrically opened inside the arm support plate 1, and two gears 331 are meshed on the transmission rack 15, one of which is meshed with the gear 331 at the upper end of the support plate 312. The clamping plate 34 has a double-arc structure and is first concave and then protruding. Its structure can adapt to the position of the patient's hand. The inner surface of the clamping plate 34 is fixedly mounted with a soft cushion layer. By installing the soft cushion layer, the user's skin can be effectively protected and pressure can be reduced.

[0028] When the wrist needs to be clamped, the transmission rack 15 is controlled to slide forward and backward, driving the gear 331 meshing with it to rotate, thereby causing the transmission rod 33 and the clamping plate 34 to move. For example, by pushing the transmission rack 15 forward, the gear 331 meshing with it rotates clockwise, driving the transmission rod 33 and the clamping plate 34 to move toward the inside of the arm support plate 1, thereby clamping the patient's wrist; by pulling the transmission rack 15 backward, the clamping plate 34 moves toward the outside of the arm support plate 1, releasing the wrist. There are two transmission racks 15, which are connected by a connecting rod 151, one side of which is fixedly connected to the sliding assembly 13. The sliding assembly 13 is movably installed in a toothed groove provided on the side wall of the arm support plate 1. The sliding assembly 13 includes a slider 131, a clamping block 132, a limit block 134, and a vertical block 133. A clamping block 132 is fixedly mounted within the slider 131. A vertical block 133 is fixedly mounted on the upper end of the clamping block 132. A stopper 134 is fixedly mounted on the front end of the vertical block 133, which is positioned above the clamping block 132. Stopper 134 slides along the toothed groove. Pressing the slider 131 causes the clamping block 132 to move the vertical block 133 and stopper 134 back and forth within the toothed groove, thereby controlling the back-and-forth movement of the transmission rack 15. This allows for gripping of patients with varying hand sizes, resolving the issue with existing devices that cannot accommodate varying hand sizes.

[0029] At the same time, based on the above-mentioned sliding assembly 13, the sliding assembly 13 includes: a slider 131, a holding block 132, a limit block 134, and a vertical block 133; the holding block 132 is fixedly installed inside the slider 131, and the upper end of the holding block 132 is fixedly installed with the vertical block 133. The front end of the vertical block 133 is located on the holding block 132 and fixedly installed with a limit block 134. The limit block 134 is slidably installed on the toothed groove (at the same time, it cooperates with the elastic element, which is not shown in the figure); the slider 131 is pressed to move, and the slider 131 is locked and cannot be moved when it is released. Its principle is similar to the pressing and sliding principle of a utility knife, which belongs to the prior art and will not be described in detail here.

[0030] Example 2

[0031] In this embodiment, based on the handheld component 4 described in Example 1, the handheld component 4 includes: an extension rod 41, an arc plate 42, a contact plate 43, a U-shaped plate 44, and an adjusting bolt 45; the extension rod 41 is fixedly mounted on the front end of the arm support plate 1, the front end of the extension rod 41 is fixedly mounted on the arc plate 42, the upper end of the arc plate 42 is fixedly mounted on the contact plate 43, the upper end of the contact plate 43 is movably mounted on the U-shaped plate 44, and the U-shaped plate 44 is adjusted in front and back position by an adjusting bolt 45 arranged inside the contact plate 43; when the patient holds the U-shaped plate, the front and back position of the U-shaped plate can be adjusted by the adjusting bolt 45 according to the size of his or her hand and the holding habit, so that the holding is more comfortable, thereby improving the convenience and comfort of the patient in using the device.
