Description

An upper extremity vascular hemostat

technical field

The utility model relates to the technical field of medical devices, in particular to an upper extremity vascular hemostatic device.

Background technique

The incidence of coronary heart disease in my country is getting higher and higher. With the advancement of technology, coronary interventional diagnosis and treatment are more and more common. The transradial puncture approach has the advantages of less trauma, fewer complications, quick postoperative recovery, and no need for braking. It has become the preferred puncture approach for coronary interventional diagnosis and treatment. Hematoma at the radial artery puncture site will inevitably occur. The incidence of complications, according to statistics, the incidence of radial artery hematoma is about 1%. At present, the number of interventional operations in China for radial artery and ulnar artery compression hemostasis per year is more than 600,000 cases, and the number of operations is increasing at a rate of 10% every year. With this is the increasing number of patients with radial artery puncture hematoma. The current clinical compression devices are all designed for the normal radial artery puncture, and can only compress the local radial artery puncture point. Once a radial artery hematoma occurs, the position of the radial artery that needs to be compressed changes, and the compression position needs to be moved to To adjust the proximal end, the existing hemostatic device cannot adjust the compression position in a large range, so the hemostatic function is lost, and the clinician can only perform manual compression with bare hands, or use bandages and other compressions based on experience. It not only brings discomfort to patients, but also consumes a lot of time of medical staff and reduces the work efficiency of medical staff.

In addition, the effect of compressing the hematoma with bare hands or hemostasis with bandages is not ideal. After the first hematoma is treated by the doctor, due to the bending of the patient's upper limb and elbow joint, the patient will develop the hematoma again, which requires repeated compression by medical staff. The harm to patients is increased, and the workload of medical staff is also increased.
