Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a hemostatic device for the radial artery puncture site after coronary angiography. Background Art
[0002] Coronary angiography is an important means for diagnosing coronary heart disease, and hemostasis at the radial artery puncture site after the operation is a key link to ensure the safety and comfort of patients. Traditional hemostasis methods, such as gauze compression or elastic bandage dressing, although simple to operate, have problems such as unstable hemostasis effect, inconvenient wound observation, long hemostasis time, and poor patient comfort. With the progress of medical technology, radial artery hemostatic devices specifically designed for after coronary angiography have emerged. Such devices utilize precise mechanical structures or pneumatic principles to achieve precise compression hemostasis at the puncture site. They are usually equipped with adjustable compression forces to ensure both hemostasis effect and avoid causing excessive compression pain to patients.
[0003] Currently, there are also corresponding compression devices. However, when the current compression devices compress the puncture point, they directly press on the puncture site of the patient over a large area, that is, all blood vessels at the puncture site are compressed. During puncture, mainly the ulnar artery is punctured, and there is no need to press on the ulnar vein, etc. If pressed, discomfort such as hand swelling and pain will occur due to poor venous return; therefore, there are still problems with local overall compression to a certain extent.
[0004] Therefore, a hemostatic device for the radial artery puncture site after coronary angiography is needed to solve the above technical problems. Summary of the Invention
[0005] To solve the above technical problems, the present invention designs a hemostatic device for the radial artery puncture site after coronary angiography, including: a fixing component, a fixing sleeve, a rotating ring, and a pressing head; the fixing sleeve is sleeved outside the fixing component, and the fixing sleeve and the fixing component are connected by a large spring. The lower end of the fixing component is movably connected to the rotating ring, the pressing head is sleeved inside the rotating ring, and the pressing head is sleeved inside the fixing component;
[0006] The fixing component includes: a fixing cylinder and a limiting block; a plurality of through grooves are circumferentially arranged on the outer side wall of the fixing cylinder, and the limiting block is movably installed on the through groove. The inner part of the fixing sleeve near the limiting block is provided with an inclined cross-section, and the lower end of the limiting block is also provided with the same inclined cross-section. By controlling the up and down movement of the fixing sleeve, the centering movement of the limiting block is controlled to clamp and fix the pressing head. At the same time, a fixing belt is fixedly installed on the outer side wall of the lower end of the fixing cylinder, and the entire device is fixed at the puncture site through the fixing belt;
[0007] Further, an annular groove is formed on the outer side wall of the pressing head for forming a limiting and fixing effect with the limiting block. At the same time, the limiting block is installed on the through groove in a sliding manner.
[0008] Further, the lower end of the fixing component is movably connected to the rotating ring by a thread.
[0009] Further, symmetric grooves are formed on both sides of the lower end of the pressing head. Small springs are installed on the grooves, and pressing blocks are fixedly installed at the ends of the small springs. The rotating ring extends to the upper end of the pressing block, and the up-and-down movement of the pressing block is controlled by the rotation of the rotating ring to further adjust the pressing force.
[0010] Further, the pressing block has a wedge-shaped structure, and a plurality of pressing columns are linearly arranged in an array at the lower end of the pressing block. The lengths of the pressing columns decrease sequentially from the inside to the outside.
[0011] Further, a display screen is fixedly arranged at the upper end of the fixed cylinder, and buttons are fixedly arranged at the lower end of the display screen.
[0012] The beneficial effects of the present invention are as follows:
[0013] The present invention designs a hemostatic device for the radial artery puncture site after coronary angiography, including: a fixing component, a fixing sleeve, a rotating ring, and a pressing head. The fixing sleeve is sleeved outside the fixing component, and the fixing sleeve and the fixing component are connected by a large spring. The lower end of the fixing component is movably connected to the rotating ring, and the pressing head is sleeved inside the rotating ring, and the pressing head is sleeved inside the fixing component.

At the same time, the fixing head is made in a detachable form, and the pressing head can be installed during use. The detachable installation setting allows it to be replaced, which can effectively reduce the risk of cross-infection and can greatly save materials at the same time.
[0014] In addition, the present invention is provided with a pressing block at the end of the pressing head. A plurality of pressing columns are arranged on the pressing block, and the pressing columns are linearly arranged in an array. By controlling the rotation of the rotating ring to control the pressing of the pressing block, and at the same time, the linearly arranged pressing columns can ensure that during pressing, the pressing pressure gradually decreases from the puncture point to the outside, and the pressing pressure around can be reduced while pressing the puncture point, that is, the pressing of the ulnar vein can be reduced while accurately pressing the ulnar artery, which can effectively prevent discomfort such as hand swelling and pain caused by poor venous return.

Specific embodiments
[0023] Embodiment 1
[0024] A hemostatic device for the radial artery puncture site after coronary angiography includes: a fixing component 1, a fixing sleeve 2, a rotating ring 3, and a pressing head 4; the fixing sleeve 2 is sleeved outside the fixing component 1, and the fixing sleeve 2 and the fixing component 1 are connected by a large spring 11, the lower end of the fixing component 1 is movably connected to the rotating ring 3, the rotating ring 3 internally sleeved with the pressing head 4, and the pressing head 4 is sleeved inside the fixing component 1;
[0025] The fixed component 1 can detachably fix the pressing head 4. When fixing, only need to directly pull the fixed sleeve 2 to achieve one-key fixing, which is fast and convenient. At the same time, the fixed head is made in a detachable form, and the pressing head 4 can be installed during use. The detachable installation setting allows it to be replaced. Specifically, the fixed component 1 includes: a fixed cylinder 17 and a limit block 13; a plurality of through grooves 12 are circumferentially arranged on the outer side wall of the fixed cylinder 17, and the limit block 13 is movably installed on the through groove 12. The inner part of the fixed sleeve 2 near the limit block 13 is provided with an inclined cross-section. At the same time, the lower end of the limit block 13 is also provided with the same inclined cross-section. By controlling the up and down movement of the fixed sleeve 2 to control the centering movement of the limit block 13, the clamping and fixing of the pressing head 4 can be achieved. At the same time, a fixing belt 14 is fixedly installed on the outer side wall of the lower end of the fixed cylinder 17, and the whole device is fixed at the puncture point through the fixing belt 14. Its specific working process is as follows: In the initial state, the fixed sleeve 2 and the limit block 13 are in a mutually limited position, that is, the inner side wall of the fixed sleeve 2 directly contacts the limit block 13, and the limit block 13 is pressed inward, and the limit block 13 forms a fixing effect on the pressing head 4; when it is necessary to release the pressing head 4, directly pull the fixed sleeve 2 downward, so that the inclined surface part (the diameter becomes larger and the distance becomes wider) in the fixed sleeve 2 moves downward, so that the limit block 13 can return to its original position, and then its clamping effect on the pressing head 4 can be released, so as to achieve detachable fixing installation. When fixing, only need to directly pull the fixed sleeve 2 to achieve one-key fixing, which is fast and convenient. A fixing ring 21 is arranged on the outer side of the fixed sleeve 2 to facilitate movement. At the same time, the fixed head is made in a detachable form, and the pressing head 4 can be installed during use. The detachable installation setting allows it to be replaced, which can effectively reduce the risk of cross-infection and can greatly save materials at the same time; the sliding mode of the limit block 13 is that a groove is opened on the through groove 12, and a spring is installed on the groove and connected to the limit block 13 (not shown in the figure). In this way, it can be clamped and fixed, and the falling of the limit block 13 can be effectively prevented; at the same time, in this embodiment, an annular groove 41 is opened on the outer side wall of the pressing head 4 to form a limit and fixing effect with the limit block 13, and the limit block 13 is installed on the through groove 12 by a sliding installation method.
[0026] A display screen 15 is fixedly arranged at the upper end of the fixed cylinder 17, and a button 16 is fixedly arranged at the lower end of the display screen 15. By providing the display screen 15, the pressing time can be displayed, enabling the doctor or the patient to adjust the pressing force according to the pressing time. Specifically, the adjustment is performed by rotating the rotating ring 3, and the number of rotation turns of the rotating ring 3 is adjusted. At the same time, the switch of the display screen 15 and the time reset can be controlled by the provided button 16. The control method belongs to the prior art and will not be elaborated here.
[0027] Embodiment 2
[0028] In this embodiment, the lower end of the fixing component 1 is movably connected to the rotating ring 3 by a thread; in the way of thread rotation, both the rotation and pushing out can be realized, and good fixation can be achieved; it is convenient to directly form a pressing effect on the pressing block 43 at the lower end of the pressing head 4 by rotation, thereby realizing the adjustment of the pressure.
[0029] Based on the above rotating ring 3, in this embodiment, grooves are symmetrically opened on both sides at the lower end of the pressing head 4, and small springs 44 are installed on the grooves. The ends of the small springs 44 are fixedly installed with pressing blocks 43; the rotating ring 3 extends to the upper end of the pressing block 43, and the up and down movement of the pressing block 43 is controlled by the rotation of the rotating ring 3 to further adjust the pressing force; the specific process is as follows: when the rotating ring 3 is rotated, the rotating ring 3 moves downward, thereby pressing the pressing block 43 to move downward. At this time, the small spring 44 is stretched, and the lower end of the pressing block 43 contacts the puncture point of the patient. Moreover, the pressing block 43 has a wedge-shaped structure for easy extrusion and is a strip-shaped structure for linear pressing; in addition, in this embodiment, in order to effectively solve the pressing situation of the parts outside the puncture point, in this embodiment, the pressing block 43 has a wedge-shaped structure, and a plurality of pressing columns 431 are linearly arrayed at the lower end of the pressing block 43; the lengths of the pressing columns 431 gradually decrease from inside to outside; the pressing columns 431 directly contact the puncture point and perform pressing, and the linear array setting enables the outward pressing force to gradually decrease, so that the pressing pressure on the surrounding area can be reduced while pressing the puncture point, that is, the pressing on the ulnar vein can be reduced while accurately pressing the ulnar artery, effectively preventing discomfort such as hand swelling and pain caused by poor venous return.
