An overall view of the arm rest 5 is as shown in FIG. 6 and is formed of, for example, a polycarbonate material that can transmit X-rays.
[0005]
[Problems to be solved by the invention]
However, when an auxiliary tool having a shape such as the arm rest 5 is employed, there is a problem that X-rays are absorbed even if the auxiliary tool is made of a material such as polycarbonate having a low X-ray absorption. Moreover, such a material such as a polycarbonate having a low X-ray absorption is expensive. Moreover, since it has a shape as shown in FIG. 6, that is, a plate shape and weight, handling is inconvenient both in storage and in installation work on the top plate. Further, as shown in FIG. 5, when fixing with the fixing belt 6, the structure of the hard plate-like arm rest table 5 whose width exceeds the horizontal dimension of the top plate 2 becomes an obstacle, and the subject 12 is stabilized. It is also difficult to fix.
[0006]
The present invention has been made in view of such circumstances, and even when the subject is larger than the standard body type, the subject can be stably held on the tabletop in a supine position. In addition, the present invention is intended to provide a medical bed mat that does not cause unnecessary absorption of X-rays.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, a medical bed mat provided by the present invention is arranged on a table top of a bed of an X-ray CT apparatus or an X-ray fluoroscopic apparatus, and on which a subject is placed. An auxiliary member that expands according to the physique of the subject is disposed on the mat, and the auxiliary member is formed of a pair of auxiliary sheets formed in a sheet shape and is formed of a material that can be deformed into a curve. ing. Furthermore, the bed mat of the present invention is provided with a pair of auxiliary sheet storage pockets on both sides of a bag-like cover for storing the top plate mat, and the auxiliary sheet is in contact with the top plate mat through the pockets. It is configured to be more detachable. Therefore, even when the subject is larger than the standard body shape, the top mat can be configured to have specifications according to the body shape, and the subject can be stably held in a supine position on the top plate.
