Description

Femoral artery and vein puncture compressor

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a thigh arteries and veins puncture compressor.

Background

Interventional therapy, which is to introduce specific instruments into a pathological change part of a human body for minimally invasive therapy by using puncture needles, catheters and other interventional devices through natural pores or tiny wounds of the human body under the guidance and monitoring of digital subtraction angiography, CT, ultrasound, magnetic resonance and other imaging devices; interventional therapy has the advantages of minimal invasion, low cost, safety, good curative effect and the like, and is the first choice treatment method for some diseases. Vascular intervention is one of the main ways of intervention, and because the blood vessels of the femoral artery and vein are large in diameter and easily reach the blood vessels of various parts of the whole body through the two cannulas, the femoral artery and vein are the most commonly used puncture points for vascular intervention.

Compression hemostasis needs to be carried out on puncture points after interventional therapy is completed, compression tools commonly used at present are elastic bandages, self-adhesive bandages and vascular suturing devices, but compression hemostasis by using the three tools has some problems: 1. when the elastic bandage is used, in order to have enough pressure on a puncture point and prevent displacement, after a gauze ball is placed on the puncture point, the elastic bandage needs to be stretched to the maximum to cover the gauze ball and then wound on the thigh root and the waist and abdomen of a patient for pressurization and fixation, the compression force cannot be adjusted, and an affected limb needs to be braked for 8-12 hours, so that pain is caused to the patient, the patient cannot tolerate pain, the compression point is easy to displace to form pseudo aneurysm or hematoma, and tension blisters are easy to generate; 2. when the self-adhesive bandage is used, although the problem that a patient forms tension blisters is solved, the self-adhesive bandage cannot generate enough pressure on a puncture point, is easy to shift, has poor stability, and cannot adjust the compression strength, and particularly, the problems of some obese patients are more obvious, so that the healing speed of the puncture point is slow, pseudo-aneurysm and hematoma are easy to occur in the hemostasis process, and the risk of secondary operation is caused; 3. the blood vessel stitching instrument is generally used for stitching femoral artery puncture points, if the blood vessel of a patient is too serious or is not properly operated, the blood vessel is easily and completely closed, the blood vessel needs to be cut immediately and then stitched again, the arterial ischemia of lower limbs is avoided, unnecessary pain is brought to the patient, and the blood vessel stitching instrument is disposable, has too high price and can also cause great economic burden to the patient.
