Description

Additional device for hysterosalpingography on digital subtraction angiography

technical field

The utility model relates to a digital subtraction angiography machine, in particular to an additional device of the digital subtraction angiography machine. The device is mainly suitable for hysterosalpingography.

Background technique

Digital subtraction angiography (Digital subtraction angiography, DSA) is the application of computer programs to convert tissue images into digital signals for input and storage, and then inject contrast agents into blood vessels through arteries or veins, and then input the second image into the computer, twice After subtraction, the digital signals are converted into a new blood vessel image with only contrast agent and no tissue background. The equipment is mainly composed of a digital mobile C-arm X-ray system and a treatment bed. Since DSA is mainly used for vascular interventional diagnosis and treatment, in order to facilitate the diagnosis and treatment operations such as real-time brain rotation DSA examination and heart multi-angle photography, the bed surface of the diagnosis and treatment bed is usually designed in a convex shape near the head of the C-shaped arm. The bed surface of the convex shape structure requires the patient to lie on his head towards the small head of the convex shape for diagnosis and treatment, because the two legs of the patient just have nowhere to fall. The above requirements greatly limit the scope of application of DSA, such as hysterosalpingography, the patient's buttocks are required to face the head of the bed (that is, the small head facing the convex shape), otherwise it is not convenient for medical personnel to operate. If the above-mentioned requirements are followed, on the one hand, because there is nowhere to place the knee support, the patient's legs can only be supported on the side of the bed, which is easy to slip, causing the patient to be extremely nervous; on the other hand, because the C-arm cannot reach the end of the bed, the medical Personnel can only lean against the bed, not only obstructed vision, but also significantly restricted activities.
