Description
Technical Field
The invention relates to the field of medical appliances, in particular to an induction pressurization femoral artery compressor.
Background
At present, the interventional therapy technology through femoral artery intubation is quite commonly applied to medical clinical work, but the femoral artery compression, bandaging and hemostasis work after interventional therapy still lacks a special instrument. After the intervention treatment of femoral artery intubation, the femoral artery needs to be subjected to compression hemostasis, and is generally bound by cross-shaped compression. The compression process is performed by the doctor in bare hands for about 10-15 minutes. When a doctor presses, the left index finger and the middle finger are applied to the puncture points, and the fingers are in a forced posture, so that the doctor can be tired, stiff and numb after a few minutes, and uneven pressing or pressing displacement can be caused, and subcutaneous hematoma and the like can appear. And some doctors with larger force exert excessive pressure, which can cause the blocking of femoral artery blood flow of patients, even the occurrence of iatrogenic damages such as arterial occlusion, intra-arterial thrombosis and the like, and increase the pain of patients.
When the pressurizing and binding are implemented, materials used by domestic doctors are different, if the universal bandage is used, the universal bandage can be wound for a plurality of times, so that the bandage can tighten skin, skin and meat of a patient are painful, and the universal bandage is also used for cross-pasting of wide and long medical adhesive tapes, so that the universal bandage cannot be used by an allergic adhesive tape patient. The doctor is limited to no special equipment, and has to self-make a 'pressurizing object' to be placed on the puncture point. Firstly, the size and the quality of the self-made pressurized material are different, and the hemostatic effect is difficult to ensure; secondly, excessive pressure can also stress adjacent femoral veins, causing venous return obstruction and even thrombosis. The non-uniformity of the materials and the application of non-special equipment can not ensure the effect and quality of the binding hemostasis.
Existing compression hemostatic devices typically require two nurses to operate, one to secure the compression hemostatic device and the other to tighten the fixation strap of the compression hemostatic device to avoid moving the compression plate during tightening of the fixation strap. Meanwhile, since the femoral artery compressor often needs to be stopped on the patient for several days, during this period, due to factors such as movement of the patient, the pressure between the pressurizing disc and the skin of the patient is easily reduced, thereby affecting the hemostatic effect.
