Description
Technical Field
The utility model relates to a medical appliance, in particular to an appliance for hemostasis of femoral artery.
Background
The femoral artery is the most common path for interventional diagnosis and treatment, has very wide function, and is mainly used for tumor intervention, nerve intervention, cardiovascular intervention and the like in clinic. The tumor intervention comprises the treatments of puncture biopsy, radio frequency ablation, particle implantation and the like of malignant tumors, the neural intervention comprises the treatments of cerebral angiography, acute cerebral infarction thrombus extraction, intracranial external artery stent implantation, intracranial aneurysm and the like, and the cardiovascular intervention comprises the treatments of coronary angiography, thrombolysis, stent implantation and the like of acute myocardial infarction. Most interventional diagnosis and treatment are carried out through femoral artery, when the femoral artery is punctured and unsheathed, the incidence rate of complications can reach 15% -35%, the main complications are bleeding, 69% of bleeding is located at the femoral artery puncturing part, and the complications are related to arterial thrombosis of lower limbs, endarterial damage, overlarge hemostasis pressure or great hematoma formed by poor hemostasis and the like. Complications can seriously affect the physical and mental health of patients and the recovery of diseases, and no strict and uniform operation rules can be followed at present.
The traditional hemostasis method after the current interventional operation mainly comprises manual pressing and a blood vessel closer. The manual compression is generally performed by compressing for 20-30 min, and then hemostasis is performed by a method of compressing with a wide adhesive tape and a sand bag, because the pressure applied by a compressor is different in magnitude, the pressure cannot be controlled according to the individual condition of a patient, and factors such as the operation proficiency and the difference of response capability influence the hemostasis effect and consume manpower. Traditional hemostasis by compression: the operator palpates femoral artery pulsation with left index finger, middle finger and ring finger 0.5 ~ 1cm above the puncture point, pressurizes gradually in the obvious position of pulsation, and the sheath pipe is pulled out to the right hand simultaneously, according to right instep artery pulsation and low limbs cyanosis condition, adjusts left finger pressure, oppresses 20 ~ 30 minutes after, loosens the pressurization finger, if the puncture point does not bleed, then presses the gauze book in the finger pressure point and fixes with the adhesive tape after, does "8" word winding with the elasticity bandage around the thigh again. If the puncture point still bleeds, the operation is repeated until the pressure dressing is performed. After the operation, about 1kg of sand bag is used for pressing the puncture part for 4-6 h, the lower limb on the operation side is braked and is absolutely bedridden for 24 h, and then the compression bandaging is removed. The method needs great labor intensity of an operator, and the physical strength of the operator can be changed along with the prolonged pressing time, so that the pressure on the puncture point is in an unstable state in the pressing process, and the occurrence of complications is increased. When a common operator finishes pressing, due to the fact that long-time exertion is excessive, shaking of both hands occurs, and the later-stage working quality of the operator is affected. Vascular closures have the advantages of shorter hemostasis time, higher immediate hemostasis rate, and fewer local complications, but are expensive. Therefore, the safe, effective, convenient, comfortable and labor-saving hemostasis of puncture points after operation and the improvement of the pressing efficiency are the topics which are commonly concerned by the interventionalists and patients, and it is necessary to find a better pressing method and apparatus to meet the clinical requirements.
