Description

Technical Field

[0001] The utility model relates to the technical field of hemostatic devices, in particular to a hemostatic device for compression after cardiovascular angiography. Background Art

[0002] Cardiac angiography is performed by inserting a very thin catheter into the human aorta, and then injecting contrast agent into the aortic blood through the catheter, so that the X-ray can display the contrast agent flowing along the blood vessels on the display screen, thereby observing the morphology of the blood vessels and the heart. However, cardiac angiography is a percutaneous interventional surgery, and pressure needs to be applied to the puncture site to stop bleeding after the operation, so a pressure hemostasis device is required.

[0003] According to a post-cardiovascular angiography compression hemostasis device disclosed in the patent with patent number CN213030763U, the patent can effectively stop bleeding on the patient's wound by arranging a hemostasis box, a first binding belt, a second binding belt, a metal spring and a pressure plate. The setting of the pressure plate can support the patient's wound to prevent more blood from flowing out. The setting of the metal spring can support the pressure plate, and can replace manual compression and hemostasis for a long time on the patient, so that the device can effectively stop bleeding and press the wound at the same time, which is convenient for people to use. However, in actual applications, the pressure plate of the compression hemostasis device is generally unable to be replaced, and the hemostasis device is usually discarded after use, which will cause waste and reduce the practicality of the device. To this end, we provide a post-cardiovascular angiography compression hemostasis device to solve the above problems. Utility Model Content

The movement of the pressure plate 6 can drive the pressure rod 507 to move, and at the same time can drive the second telescopic spring 7 to contract. The elastic force generated by the deformation of the second telescopic spring 7 can drive the pressure plate 6 to automatically reset, which can make the operation of the device more convenient and quick.

[0039] Working principle: When using the device, it is first necessary to fix it to the patient through the fixing belt 17, the first Velcro 18 and the second Velcro 19, and then rotate the turntable 12, which can drive the threaded rod 2 to rotate, and the threaded rod 2 can drive the threaded cylinder 3 to move, and the movement of the threaded cylinder 3 can drive the lifting plate 4 to move, and the lifting plate 4 can drive the fixed cylinder 502 to move, and then drive the sliding column 503 to move, and the movement of the sliding column 503 can drive the pressure plate 501 to perform surgery on the patient. Press to stop bleeding, and then when the pressure plate 501 needs to be replaced, it needs to be pressed first, and the pressure plate 6 can drive the pressure rod 507 to move, and the movement of the pressure rod 507 can drive the limiting column 504 to slide, and as the limiting column 504 slides, the first telescopic spring 505 can be driven, and when the limiting column 504 slides out from the inside of the sliding column 503, the limitation of the sliding column 503 can be released, and then the pressure plate 501 can be removed, and then replaced with a new pressure plate 501, so as to complete the replacement of the pressure plate 501.
