Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a wearable auxiliary compression hemostasis device after cardiovascular angiography in the department of cardiology. Background Art

[0002] Cardiovascular angiography is a technique used for the diagnosis and treatment of cardiovascular diseases. During the operation, the doctor first inserts a puncture needle into the patient's blood vessel, usually choosing the groin or wrist as the puncture site. Subsequently, the doctor inserts an arterial sheath into the blood vessel and, under the guidance of a guide wire and a catheter, gradually advances it to the target position, such as the heart or a specific blood vessel. Once the catheter is in place, the doctor injects a contrast agent to make the blood vessel contour and blood flow clearly visible under X-ray or other imaging devices, thereby helping the doctor accurately diagnose cardiovascular diseases.

[0003] Chinese Patent Document: CN202120939079.X discloses a compression hemostasis device after cardiovascular angiography. In this application, when the fixed block is installed, it is connected and fixed through a fixed buckle and a buckling part. Subsequently, a fixed band is sleeved on the patient's puncture part, and then the active telescopic component is rotated so that the driven tube extends out and presses the hemostatic plate against the patient's puncture part. This compression fixation method cannot adjust the pressing force, easily causes problems such as tissue damage and nerve compression, causing discomfort to the patient. At the same time, it cannot monitor the pressure size in real time and relies on experience to control the compression force. And when adjusting the length of the binding band, it mainly relies on the adjustment buckle for adjustment, which easily leads to the problem of the compression point shifting when stretching the binding band, thus affecting the compression hemostasis effect.

[0004] Chinese Patent Document: CN202111538643.8 discloses an adjustable arterial hemostat with a pressure monitoring function. In this application, a pressure sensor is used in cooperation with a display screen to display the pressure value in real time. In this application, an airbag is arranged at the bottom of the binding band to adjust the pressure of the hemostatic mechanism on the blood vessel. When adapting to limbs of different thicknesses, the length of the fixed band is adjusted by adjusting the connecting plate and locking it with a pin and a fixing hole. This adjustment method is relatively complex in operation, affecting the hemostasis efficiency, and the hemostatic plate in this application is not easy to disassemble and replace, thus easily causing the risk of cross-infection. Summary of the Invention

[0005] In view of the above problems, the present invention discloses a cardiovascular angiography auxiliary device, which realizes real-time monitoring of the compression force, meets the rapid disassembly and replacement of the hemostatic plate, and at the same time solves the problem that the wearable auxiliary hemostasis device in the prior art cannot maintain the accurate positioning of the puncture point and is prone to deviation.
