Radiation-resistant curtain used during angiography

Abstract

The invention provides a radiation-resistant curtain used during angiography. The radiation-resistant curtain comprises a transparent structure and a radiation-resistant curtain body, wherein the transparent structure is arranged on an angiography device and is used for enabling a control key to be visible in a use process; the radiation-resistant curtain body is defined by a plurality of pieces of radiation-resistant cloth. The radiation-resistant curtain is characterized in that the transparent structure is connected with the radiation-resistant curtain body; the radiation-resistant curtain body does not shield the transparent structure; the upper end of the radiation-resistant curtain body is fixed on the angiography device; the lower end of the radiation-resistant curtain body is suspended under the angiography device; in addition, a metal sheet is arranged on the radiation-resistant curtain body near the lower end of the angiography device; the radiation-resistant curtain body of a stable structure is further defined by the radiation-resistant cloth. The radiation-resistant curtain has the advantages that the assembly is convenient; the overflow of X rays during angiography can be effectively prevented; the dosage of X ray radiation to doctors in an interventional operation is obviously reduced; the radiation-resistant curtain is discontinuously connected, so that the change of a DSA (digital subtraction angiography) flat panel detector in any direction and at any angle can be met; the examination and the treatment are not influenced; meanwhile, the operation of an interventional doctor in the shielding range of the radiation-resistant curtain is not influenced.

Description

technical field [0001] The invention belongs to a safety protection medical device used in the use of a radiological diagnostic instrument, in particular to a radiation protection device when the radiological diagnostic instrument is used in angiography, and in particular to a radiation-proof curtain used in angiography. Background technique [0002] At present, when hospitals are examining and treating patients, many items involve the use of X-rays, such as interventional diagnosis (angiography) and treatment (interventional therapy) guided by an X-ray angiography machine (DSA machine). In recent years, interventional therapy has developed rapidly. At present, interventional therapy has become the third largest treatment method alongside internal medicine and surgery, and the number of patients undergoing interventional therapy is increasing year by year. [0003] Angiography is an interventional examination method, injecting a contrast agent into blood vessels, because X-r...
