The structure is ingenious and the function is powerful. By using this device, it is not only convenient for the medical staff to push the contrast agent into the blood vessels of the patient, thereby effectively overcoming the problem of high viscosity of the contrast medium, but also convenient for the medical staff to know the remaining contrast dose inside the syringe. , and ultimately bring convenience to the medical staff while also saving labor and enhancing the stability of the device. At the same time, the material of the observation board is transparent plexiglass, and the material of the protective pad is sponge, which has good softness, making it compatible with Patient skin soft contact, non-slip cover is to improve the stability of medical staff holding the handle.
