A radial artery pressurization and compression hemostasis device

technical field

The utility model relates to a medical hemostat, in particular to a disposable compression hemostat acting on the radial artery, which belongs to the technical field of medical instruments.

Background technique

Interventional surgery is already a routine treatment method in medical departments such as cardiology and neurology. The advantage of interventional surgery is that doctors can enter the patient's body for treatment without using general anesthetics or surgery. Under normal circumstances, interventional diagnosis and treatment operations, especially interventional operations in the Department of Cardiology, are performed through the patient's radial artery access. The interventional operation of the radial artery access has fewer complications, and the patient is bedridden for a short time to restrict activities. Low cost and other advantages, but like other arterial puncture operations, complete hemostasis of arteries after intervention is an important part to prevent bleeding at the puncture point after interventional surgery.

Usually after the interventional operation is completed and the catheter is removed, the doctor or medical professional applies pressure at the puncture point of the arterial catheter to achieve hemostasis and closure of the arterial puncture point. Hemostasis and closure of the arterial puncture point require continuous and stable pressure, generally the initial pressure After a period of time, it is necessary to gradually reduce the pressure so that the tissues downstream of the blood vessels can get a rich blood supply. At present, hemostasis at the radial artery puncture point is mainly through artificial hemostasis or mechanical pressure equipment, and artificial hemostasis is through manual pressure by medical staff or applying bandage pressure to stop bleeding. This method consumes a lot of physical strength and time for medical staff; the existing mechanical pressure The equipment is generally inflated or pushed and pressurized through airbags or knobs, which can reduce the physical exertion of medical staff and improve the efficiency of hemostasis. However, there are two significant problems with this type of equipment. One is that the hemostasis effect is poor, and the success rate of hemostasis is not as high as artificial hemostasis. There are many cases of bleeding; the second is that the venous return is blocked due to the high pressure on the arm, which leads to swelling and purple of the hand and arm, which increases the discomfort and panic of the patient.
