Description

Hemostatic device {A CLAMP-TYPE STANCHING APPARATUS}

The present invention relates to a hemostatic device, in particular, to improve the problem of the method of hemostasis and the post-hemostatic management method by the existing operator's hand or other method in the hemostasis after radial artery puncture for angiographic diagnosis and interventional treatment. It is about a hemostatic device.

In general, the diagnosis and treatment of cardiovascular or cerebrovascular disease uses a method of drilling a hole of about 1.5 to 3 mm in the femoral artery and inserting a catheter.

However, when access to the femoral artery is blocked, when hemostasis is expected after a femoral puncture, or when the procedure is performed on the same day of the hospital. The radial artery is punctured and angiography or various intravascular procedures are performed through the radial artery.

In addition to the interventional procedures in the cardiac field, the use of the cardiovascular system for diagnosis and treatment is increasing.

The advantage after the procedure to the radial artery is that the femoral artery approach, which requires prohibition of upper and lower body movements for 3 to 6 hours, is relatively easy to hemostasis without significant limitations on the patient's activity.

The radial artery is located very shallowly, making pulse palpation easier and easier to compress.However, safe hemostasis requires at least one to two hours of pressure, without bleeding, tingling and pain at the puncture site. There was a technical difficulty in maintaining pressure alone.

Currently, hemostasis method in Korea is mainly used to wrap the wrist around the puncture hole by using the finger of the operator to make the gauze thick or by using a small glass bottle, and wrap it with a bandage on it. It became.

In this case, in order to prevent pain and numbness of the hand, it is important to effectively compress the blood vessel hole in a range that does not completely block the blood flow of the ulnar artery or radial artery to the hand. In particular, during the two to three hours of maintaining hemostasis, there should be no compression of the veins that go up and down the wrist to the heart.

In addition, it is important to design a form that can sustain the hemostatic action stably so that the gauze or other substance pressing the blood vessel hole during the hemostasis maintenance does not move to another place by the movement of the wrist.

However, such a conventional band-aid or hemostatic method by the operator's hand includes drawbacks such as complications during maintenance of hemostasis by obstructing blood flow by closing the arteries going to the hand and the veins coming from the hand to the heart. Doing.

In other words, the conventional hemostatic method does not guarantee the opening of arteries or veins during the maintenance of hemostasis due to the pressure of the band-aid wound around the wrist, which leads to damage of blood vessels, resulting in pain such as hand pain and swelling of the hand. There are drawbacks such as:

The present invention is to solve such a conventional problem, the radial artery hemostatic device in the form of a clamp (clamp) is the main technical problem to provide a simple, effective and safe hemostasis.

Hemostatic device of the present invention for achieving the above object,

The center portion is crossed to hold the first and second handle grips formed at the rear ends of the two first and second handles to catch blood vessels such as the radial artery or vein so that the first and second handles are close to each other. A hinge part which is rotatably coupled to each other,

A pressing member joined to an inner side of a tip of the first and second handles,

It characterized in that it comprises a pressure adjusting member coupled to protrude to face the front inner side of the first and second handle grip.

The radial artery hemostatic device in the form of a clamp according to the present invention provides a simple, effective and safe hemostasis. Unlike the conventional method, it effectively compresses only the puncture site from the artery to the hand and the heart to the heart. Ensure the opening of the coming veins. This can prevent the complications that can occur during maintenance of hemostasis by not disturbing the blood flow, and in particular, can provide a simple, effective and safe in radial artery hemostasis after catheterization and treatment using angiography.
