Description

[Correction according to Rule 26 21.09.2015] A radial artery compression and hemostasis device

Technical field

The invention relates to a medical hemostat, in particular to a disposable compression hemostat acting on a radial artery, belonging to the technical field of medical instruments.

Background technique

Interventional surgery is a routine treatment for medical departments such as cardiology and neurology. The advantage of interventional surgery is that the doctor can enter the patient's body without using general anesthesia or without surgery. Usually, the interventional diagnosis and treatment, especially the interventional surgery of the cardiology department, is achieved through the patient's radial artery access. The interventional procedure of the radial artery pathway has fewer complications, and the patient's bed rest activity is short. The cost is low, but like other arterial puncture operations, complete hemostasis of the postoperative arteries is an important part of preventing bleeding at the puncture site after interventional surgery.

Usually the interventional procedure is completed. After the catheter is removed, the doctor or medical professional applies pressure at the arterial catheter puncture point to achieve hemostasis and closure of the arterial puncture point. The hemostasis and arterial puncture point closure require a constant pressure, usually the initial pressure. Higher, after a period of time, it is necessary to gradually reduce the pressure, so that the blood vessels downstream tissue get rich blood supply. At present, hemostasis at the radial artery puncture point is mainly controlled by manual hemostasis or mechanical compression equipment to stop bleeding. Manual hemostasis is manually pressed by a medical staff or applied with a bandage to stop bleeding. This method consumes the physical strength and time of the medical staff; the existing mechanical pressurization The device generally inflates or pushes the air through the airbag or the knob, which can reduce the physical exertion of the medical staff and improve the hemostasis efficiency. However, there are two significant problems in the device, one is that the hemostasis effect is poor, and the hemostasis success rate is not artificially high. The oozing condition is more; the second is that the venous return is blocked due to the large pressing force of the arm, which causes the hand and the arm to swell and purple, which increases the patient's discomfort and panic.
