CA 2417850

A radiation protection system (10) around a patient (12) on an x-ray table (14) includes a radiation protection wall (20) with an opening around the x- ray table (14), a radiation screen (22) over the patient, and a flexible interface (24) joining the cubicle (100) and the x-ray table (14). The wall (20) shields medical personnel in an operating region (16) from most radiation output by an x-ray emitter. The radiation screen (22) is attached to the x-ray table (14) such that it can be retracted to the foot of the x-ray table (14) and extended over the patient (12) such that it is interposed between the patient (12) and the medical personnel. The interface (24) has flexible joints (38) attached to the wall (20) and a flexible radiation-resistant skirt (40) that joins the wall (20) to the screen (22) and covers the opening (26) in the wall. An access port (46) may be formed in the screen, and a shielding cloak (48) can cover the access port (46) to surround medical instruments that are threaded through the port (46) and inserted into the patient.

L'invention concerne un système de radioprotection (10) entourant un patient (12) placé sur une table de rayons X (14), ce système comprenant une paroi de radioprotection (20) dotée d'une ouverture entourant la table de rayons X (14), un écran bloquant les rayonnements (22) et disposé au-dessus du patient, et une interface souple (24) raccordant l'habitacle (100) et la table de rayons X (14). La paroi blindée (20) protège le personnel médical se trouvant dans la zone de fonctionnement (16), de la plupart des rayonnements produits par un émetteur de rayons X. L'écran bloquant les rayonnements (22) est attaché à la table (14) de façon à pouvoir être escamoté sur l'extrémité de celle-ci et déployé sur le patient (12), afin d'être interposé entre le patient (12) et le personnel médical. L'interface (24) possède des joints souples (38) fixés sur la paroi (20) ainsi qu'un rideau souple, résistant aux rayonnements (40), joignant la paroi (20) à l'écran (22) et recouvrant l'ouverture (26) ménagée dans la paroi. Un orifice d'accès (46) peut être formé dans l'écran, et un masque de blindage (48) peut recouvrir cet orifice (46) de manière à entourer les instruments médicaux filetés à travers l'orifice (46) et introduits dans le patient.
