Description
Technical Field
The utility model relates to the field of medical appliances, in particular to a single-hand adjustable elastic knob type arteriovenous inscription tourniquet.
Background
In the hemodialysis process, a central venous indwelling catheter or a direct puncture artery and vein is needed, compression hemostasis is needed in the later period, for example, the conventional radial artery compression tourniquet is provided with sticking buckles at two ends of a fixing band, a pressing plate is arranged in the middle of the fixing band, and an air bag is arranged below the pressing plate. When in use, the air bag is pressed on the puncture part, and then is inflated by a special inflation syringe, and the inflated air bag is pressed on the puncture part, so that radial artery hemostasis is realized. The air is pumped out after a special inflation syringe is connected with the air bag during deflation. The problems are: the area of the contact between the air bag and the skin is large, the air in the air bag needs to have large pressure to effectively press hemostasis at the puncture part, when the pressure is enough, the skin contacted by the fixing belt and other places also bears the same pressure, the fixing belt is a plastic belt, the edge of the fixing belt forms shearing force on the skin, the fixing belt causes unsmooth blood flow under the skin in a plurality of hours of hemostasis, the patient is numb and blue-purple, the unsmooth blood flow further swells the skin, serious patients even cause nerve injury and arterial occlusion, and many patients cannot tolerate the phenomenon is particularly common in fat patients because of pain. And insufficient compression time or insufficient pressure can cause bleeding, hemorrhage, or even subcutaneous hematoma.
When the medical staff performs compression hemostasis, the operation of two persons is needed, one person binds the fixing belt, and the other person inflates the air bag by using a special inflation syringe, so that the working efficiency is low. The skin is engorged with blood and swelled, and the air pressure in the air sac is regulated for a plurality of times, so that the operation of inflation and deflation is complicated.
Because the air sac part is contacted with blood, the disposable blood bag can only be used once, has large waste and is not environment-friendly.
Chinese patent document CN101843513a discloses a compression tourniquet, a pressing plate is mounted on a fixing strap, a plurality of air bags are arranged at other positions except the pressing plate on the fixing strap, and the air bags are connected with the compression air bags through communicating pipes; one end of the pressing plate is provided with a supporting bracket, and a pressing head is arranged at a position close to the other end of the pressing plate. The defects are overcome to a certain extent, but the problem of complex operation still exists, the pressing plate is required to be reliably fixed in the process of inflating by using the compression air bag, displacement is avoided, and a medical staff still has certain difficulty in operation. And the structure of the pressing head in the pressing plate is a structure with a raised center, so that compression molding is difficult.
