Description

Arterial pressure hemostasis

The utility model relates to a hemostatic device, in particular to an arterial pressure hemostasis device which is suitable for external hemostatic closure and hemostasis by transfemoral (or venous) perforating arterial (or venous) perforating point and other arterial (or venous) hemorrhage. It belongs to the field of medical devices. Background technique

With the improvement of medical technology and the improvement of medical equipment conditions, percutaneous transfemoral (桡) arterial intervention has become a commonly used clinical operation technique. Such as coronary angiography and left ventricular angiography, intravascular ultrasound, coronary stenting. As a result of the significant improvement in people's living standards, it has brought about the impact of harm to human health. The incidence of hypertension, diabetes, and coronary heart disease has increased significantly. In particular, the incidence of coronary heart disease has nearly quadrupled in the past two decades, making the mortality rate of coronary heart disease the first. At the same time, the clinical treatment of coronary heart disease and coronary heart disease has undergone a fundamental change, from the original drug treatment of dissociation, expansion, and thrombolysis to interventional catheter therapy, resulting in mortality and recurrence rate. Significantly lower. At present, there are about 1000 cases of coronary heart disease undergoing balloon stent intervention every day in China. This type of intervention involves first percutaneous transfemoral femoral artery bypassing, and then the balloon and stent are placed through a catheter to the stenotic or occluded tubular artery for expansion and implantation, allowing blood to be reperfused into the myocardial tissue to treat coronary heart disease. When the operation is over, the arterial shell on the femoral artery is pulled out, so that a hole of 0. 2-0. 7 cm is left on the wall of the femoral artery to cause bleeding.

Currently used hemostasis methods include manual compression, mechanical compression, and vascular occlusion. These three methods have advantages and disadvantages for stopping bleeding.

First, manual compression: artificial compression of the femoral artery for 15-40 minutes, the muscle tissue of the femoral artery wall contraction, and platelet coagulation, thus forming a thrombus and causing a brief hemostasis, and then use local external pressure for 24 hours to achieve permanent hemostasis. This method of hemostasis, one of which causes many serious illnesses, endangers the patient's life. The most common complications are local hematoma, retroperitoneal hemorrhage, and the risk of pseudo-arterial flow and amputation during local compression of the femoral artery. Second, the patient suffers tremendous pain, the patient has to lie on his back for 12-24 hours, and the abdomen and lower limbs are not allowed. The activities, while suffering from the pain of bandages and sandbags. Third, the medical staff must pay a strong labor force, standing with both hands and pressing the femoral artery of the patient through the sputum for 30-40 minutes.

Second, mechanical compression: The hemostasis method is roughly divided into two types: one is the balloon compression tourniquet (such products are not suitable for femoral artery products), the shortcoming is that you can not directly observe the bleeding point of the piercing point, can not display the pressure Can not accurately apply pressure, poor fixation, can not achieve the ideal hemostasis effect; the other is the spiral arterial pressure hemostasis, it is by rotating the spiral handle, so that the pressure plate is constantly pressed through the point, the pressure is adjusted by the spiral handle The rotation depth is adjusted, so the pressure given to the piercing point can only be adjusted by the doctor's experience, and the pressure applied to the piercing point cannot be displayed, so the optimal hemostasis effect cannot be achieved.

Third, the occlusion technique: The most common three types: The first is to use a kind of beef tendon collagen, which is made into a collagen sponge to fill the femoral artery to achieve the purpose of stopping bleeding. The second is to use a biomaterial and collagen that is easily absorbed by human tissue to cause a sandwich plug, which is placed between the inner and outer membranes of the femoral artery to achieve hemostasis. The third is to implant the biological suture U-shaped suture of the femoral artery to achieve hemostasis. There is a large amount of clinical evidence that there are still many unsatisfactory complications in biological occlusion and hemostasis, which will endanger the patient's life, such as major bleeding after the retroperitoneum. Since most of the patients have a history of hypertension, the diameter of the femoral artery is small, and the cost is high, some patients will have a rejection reaction, and the utilization value of biological adhesion and hemostasis is relatively small.

1. When using, first confirm that the dorsal artery pulsation is normal, then confirm the femoral artery penetrating point, withdraw the arterial sheath by 2cm, and cover the femoral artery through the 2-3 layers with sterile gauze. The base 1 is pressed in the direction of the groin to press the platen 6 against the femoral artery.

2. Then tighten the strap 10 around the groin and tighten it tightly. The fixing of the fixing band 10 must ensure the balance of the base 1 and the pressure plate 6 is fixed.

3. The airbag 5 is inflated by the inflator (as long as any inflatable device capable of inflating the inside of the airbag, such as the existing inflatable ball 13 on the market), and the airbag 5 is expanded by inflation, thereby pushing the inner sleeve and The pressure plate 6 connected under the inner sleeve of the innermost layer moves downwards, that is, in the direction of the penetration point, and controls the expansion and contraction of the pressure plate 6 to pressurize the femoral artery (or the radial artery), and the pressure inside the balloon 5 It can be displayed on the pressure gauge. Firstly, when the pressure reaches 20~30 mmHg, confirm that the pressure plate 6 is stable to the hemostasis point (ie, the penetration point). When the pressure balance is stable, the arterial sheath is removed; then the pressure is inflated to a temperature higher than the systolic pressure of 50 mmHg. The dorsal artery pulsation should be slightly weakened but not disappeared; after 5 minutes, the pressure is adjusted to be higher than the systolic pressure by 10-15 mmHg, and then the pressure can be adjusted according to the condition, but not lower than 60 mmHg to relieve the hemostatic device 6 hours after extubation. The patient can get out of bed after 2 hours in bed.
