Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. 1 is a perspective view showing the top of the cassette holder according to the embodiment of the present invention, FIG. 2 is a perspective view showing the cassette holder inserted under the bed board of the medical bed, and FIGS. 3 and 4 show the structure of the cassette holder. (a) is an overall view, (b) is an enlarged view of the rod, FIG. 5 is a perspective view showing a cassette holder inserted into a medical bed, and FIG. 6 is an enlarged view near the rods 21 and 22.

As shown in FIG. 2 , in the medical bed 10 , an attachment portion 12 into which the cassette holder 1 is inserted is provided below a bed board portion 11 on which a patient lies. FIG. 5 is a diagram showing the mounting portion 12 by lifting the bed board portion 11 from the bed frame 10 . As shown in FIG. 5 , the mounting portion 12 is provided with a guide rail 15 extending parallel to the insertion direction 6 of the cassette holder 1 . The cross-sectional shape of the guide rails 15 is L-shaped, the guide rails 15 are fixed on the bed frame 10, and a pair is arranged on both sides of the bed.

As shown in Figure 1, the holder main body 2 of the cassette holder 1 has vertical walls 2a, 2b, 2c, 2d on the four sides of its rectangular bottom plate, and the cassettes are fitted and stored in the vertical walls 2a, 2b, 2c, The space enclosed by 2d. At one end in the longitudinal direction of the cassette holder 1 (the rear end in the insertion direction 6 ), a detachable cover 3 is provided, and fixing members such as rods and connecting rods, which will be described later, are provided inside the cover 3. . And, one side of the cover 3 is fitted with one side 2a of the cassette.

On two sides of the main body 2 of the cassette holder 1 parallel to the insertion direction 6 , there is provided a central marker 4 for confirming the position of the cassette holder 1 in the bed. In addition, on the two sides parallel to the insertion direction 6 of the cage main body 2, two rollers 5 that can rotate around the rotation axis perpendicular to the insertion direction 6 are respectively provided. It is surface-guided and rolls on the L-shaped bottom. Thus, the cassette holder 1 can reciprocate in the insertion direction 6 along the guide rail 15 with the roller 5 guided by the guide rail 15 and rolling on the guide rail 15 .

As shown in FIG. 1 , at the rear end portion of the cassette holder 1 in the insertion direction 6 , the holder fixing member of the present embodiment is provided in a region where the cover 3 is disposed. That is, at both ends in the width direction of the holder body 2 (both ends perpendicular to the insertion direction 6 ), fixed rods 21, 31 protruding outward from the holder body 2 and a rotation rod 22, 32 and barriers 25,35. As shown in FIGS. 3 and 4 , the fixing rods 21 , 31 are fixed to the holder main body 2 with their length directions perpendicular to the insertion direction 6 . The rotation rods 22 , 32 are rotatably supported by rotation shafts 23 , 33 , respectively, and the rotation shafts 23 , 33 are provided on the holder body 2 so that their axial directions are perpendicular to the holder body 2 . The blocking pieces 24, 34 are also rotatably supported on the rotating shafts 23, 33, respectively, and the rotating rods 22, 32 and the blocking pieces 24, 34 are respectively fixed to each other and have an integrated structure. Therefore, the rotation levers 22, 32 and the stoppers 24, 34 rotate in the same direction around the rotation shafts 23, 33 at the same time. At the top of each stopper 24,34, there are contact portions 25,35. When the stoppers 24,34 rotated outward, the contact portions 25,35 were in contact with the guide rail 15. The cassette holder 1 is locked on the guide rail 15 by frictional force. Surfaces of the contact portions 25 and 35 are covered with rubber-based materials to increase friction with the guide rail 15 . As a result, the locking force between the cassette holder 1 and the guide rail 15 , that is, the braking force increases.

As shown in Figure 6, on the rotating shaft 23 of one rotating rod 22, in addition to the rotating rod 22 and the blocking member 24, a rotatable connecting piece 26 is also supported, and the connecting piece 26 is connected to the rotating rod 22 and the blocking member 24. Fixed as one, while rotating in the same direction. In addition, a connection piece 36 is also fixed at the center of the other stopper 34 . Furthermore, a connecting rod 41 rotatable with respect to the connecting pieces 26 , 36 is connected between the top end of the connecting piece 36 and the end of the connecting piece 26 separated from the rotation shaft 23 . Thus, the stopper 24 and the stopper 34 rotate in conjunction. That is, when the blocking member 24 rotates to the direction in which its contact portion 25 contacts the guide rail 15, the blocking member 34 also rotates to the direction in which its contact portion 35 contacts the guide rail 15, and when the blocking member 24 leaves the guide rail to its contact portion 25 When rotating in the direction of 15 , the blocking member 34 also rotates in the direction in which the contact portion 35 is away from the guide rail 15 .

In addition, as shown in FIG. 3 , FIG. 4 , and FIG. 6 , the compression spring 27 biases the stopper 24 in a direction to press the guide rail 15 . As a result, the contact portions 25 , 35 of the stoppers 24 , 34 are always in contact with the guide rail 15 .

Next, the operation of the cassette holder and the medical bed of the present embodiment configured as above will be described. First, as shown in FIG. 2 , the cassette holder 1 for accommodating unused cassettes is inserted into the mounting portion 12 below the bed board portion 11 of the bed 10 . At this time, as shown in FIG. 5 , the rollers 5 of the cassette holder 1 are guided by the L-shaped vertical surface of the guide rail 15 and roll on the horizontal portion of the bottom surface. As a result, the cassette holder 1 is guided by the guide rail 15 and inserted into the attachment portion 12 below the bed board portion 11 . When inserting the cassette holder 1 , the operator moves the cassette holder 1 while holding the fixed lever 21 and the rotating lever 22 . In this way, by holding the fixed rod 21 and the rotating rod 22 , as shown in FIG. 3 , the contact portion 25 of the blocking member 24 is in a state of leaving the guide rail 15 . In addition, as long as the fixed rod 31 and the rotating rod 22 disposed on one side of the cassette holder 1 are grasped, the fixed rod 31 and the rotating rod 32 disposed on the other side of the cassette holder 1 are also brought into close proximity via the connecting rod 41 at the same time. state, the contact portion 35 of the blocking member 34 is also away from the guide rail 15 . In this way, when moving the cassette holder 1 , the fixed lever 1 and the rotating lever 22 are held so that the contact portions 25 , 35 of the stoppers 24 , 34 are separated from the guide rail 15 . In addition, it is of course possible to hold the fixed rod 31 and the rotating rod 32 instead of holding the fixed rod 21 and the rotating rod 22 .

Then, when the cassette holder 1 is inserted to a predetermined mounting position, the holding of the fixing lever 21 and the rotating lever 22 is released. Like this, as shown in Figure 4, stop member 24 utilizes the biasing force of compression spring 27 to rotate to its contact portion 25 and the direction that guide rail 15 contacts, and another stop member 34 also utilizes connecting rod 41 to its contact portion 35 and guide rail. 15 Direction of contact rotation. Thus, since the contact portions 25, 35 of the stoppers 24, 34 are in contact with the guide rail 15, the contact portions 25, 35 push the guide rail 15 by the compression spring 27, therefore, utilizing the frictional force between the contact portions 25, 35 and the guide rail 15, The braking force acts on the cassette holder 1 and stops at the prescribed installation. Therefore, even if the bed moves or vibrates, the position of the cassette holder 1 does not change. In addition, even if the entire bed board portion of the bed is turned so that the foot side becomes upward or the head side becomes upward in accordance with the stretching operation of the bed, the cassette holder 1 does not move.

In addition, by providing the guide rail 15 substantially over the entire length of the bed top portion 11, the cassette holder 1 can be attached to any position of the bed top portion 11, and X-ray imaging of the patient's whole body can be performed.

In addition, in the above-mentioned embodiment, although rods and stoppers are provided on the rear end portion of the cassette holder 1, the positions of these components are arbitrary, and they can be provided at the rear end of the cassette holder 1 by utilizing the bed structure or the like. any position.
