Description

Technical Field

[0001] The invention relates to the technical field of hemostatic compression devices, and in particular to a hemostatic compression device used for a femoral artery puncture point. Background Art

[0002] Femoral artery puncture is one of the common ways of interventional diagnosis and treatment. Vascular complications during the operation at the puncture point are always a problem that every interventional physician has to face from time to time. The methods for hemostasis at the puncture point after femoral artery intervention include manual compression hemostasis, mechanical compression hemostasis, and vascular closure device hemostasis. The traditional manual compression method has been used clinically for a long time, but long-term compression hemostasis and bed rest not only increase the workload of medical staff, but also increase the pain of patients. Since the mid-1990s, with the widespread use of vascular closure devices and various mechanical compression devices, the time patients spend in bed after surgery has been shortened to a certain extent, which has improved the comfort of patients, but it has also inevitably brought some complications. Therefore, the desire of interventional puncture surgery patients and physicians for new hemostasis methods has never stopped.

[0003] Among them, instrument compression is more widely used, but the compression area of ​​the pressure plate is small. If the high pressure continues to compress the blood vessels at the puncture site, the patient may experience a vagal reflex. In addition, the compression position is easy to move, and the pressure cannot be detected when the puncture point is compressed. If it is compressed too tightly, bruises, skin blisters, and pain and discomfort to the patient may occur. If it is compressed too lightly, it may not be able to stop bleeding and bleeding may occur. At the same time, the compressor cannot be completely fixed and is prone to movement, resulting in compression failure. Therefore, a person skilled in the art herein proposes a hemostatic compression device for the femoral artery puncture point. Summary of the invention
