Radial artery hemostat

Abstract

The invention discloses a radial artery hemostat which is applicable to field of medical apparatus. The radial artery hemostat comprises a hemostasis plate and fixing straps connected to two ends of the hemostasis plate. A transparent pressure plate which can elastically deform along normal of the hemostasis plate is disposed on the hemostasis plate. The side wall of the pressure plate is provided with scale marks along the elastic deformation direction. The hemostasis plate is provided with a pressure plate capable of elastic deformation. During use, the hemostasis plate is fixed above an incision area through the fixing straps, the pressure plate presses an incision to generate elastic deformation and displays pressure through the scale marks, and quantified hemostasis pressure is achieved. In addition, the pressure plate is made of transparent materials, visualizing requirements of the incision are satisfied. By pressure elastic deformation of the pressure plate for pressure hemostasis, pressure is visualized and readable. The radial artery hemostat is simple in structure, convenient to operate and safe to use.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a hemostat. Background technique [0002] Radial artery hemostasis is mainly used for arterial hemostasis after radial artery puncture, and its clinical fields include: blood purification, interventional contrast imaging examination and treatment, continuous invasive blood pressure dynamic monitoring, arterial hemodynamic blood sample collection and Vascular access during rescue, etc. After the above puncture, it is necessary to compress the radial artery for a long time to achieve the effect of hemostasis. Among them, it is very important to control the hemostatic pressure. If the hemostatic pressure is too small, it will cause hemostasis failure. In the case of bleeding from the patient's incision, if the pressure is too high, it will easily lead to reactions such as blood flow blockage and arterial thrombosis. [0003] At present, the radial artery hemostasis methods mainly include man...

AI Technical Summary

Problems solved by technology

Among them, it is very important to control the hemostatic pressure. If the hemostatic pressure is too small, it will cause hemostasis failure. In the case of incision bleeding in patients, if the pressure is too high, it will easily lead to blood flow blockage and arterial thrombosis.

[0003] At present, the radial artery hemostasis methods mainly include manual finger pressure bandage and hemostasis using a hemostat. The manual finger pressure method is difficult to quantify and cannot guarantee effective hemostatic pressure. Moreover, long-term finger pressure will cause finger numbness and lead to hemostasis failure. Compression methods also restrict the patient's movement

Among the existing hemostats, the balloon-type hemostat can better control the pressure, but because the balloon is located directly above the arterial incision area, it limits the doctor's observation of the incision, and it needs to be equipped with a balloon and a manometer, which increases the cost

The helical hemostat also has the disadvantages of invisible incision and high cost due to the configuration of pressure gauges, and it is easy to cause lateral stretching of the incision during the screw tightening process, which affects the hemostatic effect and safety

Although the elastic pressurized hemostat has simple structure, visible incision, and convenient operation, it cannot quantify hemostasis, so it relies entirely on the operator's experience and feeling, and is affected by the patient's tolerance and the tissue structure of the compressed part. , the hemostatic effect is difficult to guarantee, and it is easy to break the hemostat due to excessive binding tension, which has great potential safety hazards
