Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a brachial artery compression hemostat. BACKGROUND

[0002] With the popularization of coronary angiography intervention treatment, more and more patients benefit from coronary angiography intervention treatment, and coronary angiography intervention has become an important method for diagnosing and treating coronary heart disease. Nowadays, the preferred puncture point for coronary angiography intervention treatment is the radial artery. However, with the increase in the number of interventional diagnosis and treatment, the radial artery is relatively small in diameter, is prone to spasm after multiple punctures, and has many branches. Some patients cannot successfully undergo interventional diagnosis and treatment through this route, and more and more patients need secondary or even multiple interventional treatment. The incidence of radial artery occlusion is gradually increasing, and brachial artery puncture is the preferred puncture method after radial artery puncture fails.

[0003] However, in the existing technology, for example, in the angiography of patients with coronary heart disease, the brachial artery needs to be hemostatic after the sheath is pulled out. Nowadays, elastic bandages are used for hemostasis. The elastic bandage needs to be pressed on the wound for 10-15 minutes after the sheath is pulled out, which increases the operation time of the doctor, and there is a certain possibility of vagal hyperactivity during arterial compression, causing unstable vital signs of the patient.
