本発明は医療診断装置用寝台の天板に関し、特に、寝台
に載置さｎる被検体の荷重によるたわみを除去すること
のできる天板支持部材移動機構に関する。Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a top plate for a bed for medical diagnostic equipment, and in particular, a top plate support that can eliminate deflection due to the load of a subject placed on the bed. It relates to a member moving mechanism.

る。In a medical diagnostic device such as a radiation CT device, a radiation source and a radiation detector that face each other around the patient are rotated around the body axis of a subject placed on a bed, such as a patient. , a tomographic image of the patient is obtained. In this case, the top of the bed on which the patient is placed may sag under the weight of the patient. If the patient's body protrudes from the area to which A-rays are irradiated, accurate tomographic images cannot be obtained.
したがって、寝台の天板は患者による荷重が負荷さｎて
もたわまないことが必要である。しかじな、。Therefore, it is necessary that the top plate of the bed does not sag even under the load imposed by the patient. That's true.
がら、荷重によるたわみを解消するために天板の厚みを
厚くすると、放射線の透過率が低下するばかシか、寝台
製造時のコストが大きくなってしまう。However, if the thickness of the top plate is increased to eliminate deflection due to the load, not only will the radiation transmittance decrease, but the manufacturing cost of the bed will also increase.

傾斜部１９を有している。Next, FIG. 2, which is a detailed view of the installation of the top plate 1 of the bed for medical diagnostic equipment shown in FIG. 1, shows the state of the top plate 1 before examination. A support member 8 is attached to the lower part of the top plate 1, and a row 29 attached to the end thereof supports the top plate 1 when it is moved to the inspection position. Support member 8
A spring 11 for returning the support member 8 to the left in the figure is attached to the convex portion 10 at the right end. Further, a lever 16 is attached to a pin 1 on a convex portion 12 located approximately in the center of the support member 8.
4) It is rotatably mounted. Rollers 15 and 16 are attached to the tip and middle portions of the lever 13, respectively. The row 215 at the tip is located at a position where the end of the top plate 1 comes into contact, and the row 216 at the middle portion is configured to run on a guide guide 18 attached to a member 17 that constitutes a part of the side plate 4. has been done. The surface of the guide 18 on which the roller 16 runs is approximately parallel to the moving surface of the top plate 1, and the left end thereof has an inclined portion 19 having an angle of 45° with the moving surface of the top plate 1. ing.
上述の構成において次にその作用を説明する。The operation of the above-mentioned configuration will now be explained.

る。In FIG. 2, a patient as a subject is placed on the top plate 1. The top plate 1 on which the patient is placed is moved toward the examination position (to the left in the figure). Then, the tip of top plate 1 is lever 1
6 and comes into contact with a roller 15 attached to the roller 15. A force is applied to the lever 16 to rotate it counterclockwise around the pin 14, but since the roller 16 attached to the middle part of the lever 16 is on the guide 18, the row 216 runs on the guide 18.
それと供に、レバー１６が取付けられた支持部材８は引

6 travels a certain distance on the guide 18, the row 216 travels along the slope 19 of the guide 18. Then, the lever 16 rotates counterclockwise around the pin 14, and the row 515 provided at the tip of the lever 16 no longer comes into contact with the top plate 1, and the lever 13 and the top plate 1 are brought into engagement. I won't.

よフ尤の状態に戻る。Next, when the top plate 1 returns to its original state after the inspection is completed, first only the top plate 1 moves to the right. When the top plate 1 reaches a certain distance mR, the top plate 1-7 that was holding down the head of the row 215 until now
) Without E, the tension spring 11 causes the jaw 216 to start moving up the inclined part 19 of the guide 18, that is, the lever 13 rotates clockwise and the roller 15 comes into contact with the end of the top plate 1. Further, as the top plate 1 returns, the support member 8 also returns to its relaxed state due to the tension spring 11.

Deflection of the top plate due to the patient's weight can be eliminated. In addition, after the top plate is returned to its original state after the inspection is completed, the support plate that supported the top plate during the inspection also returns to its original state due to the spring force, so that it does not protrude much beyond the top plate and can be connected to other devices. interference is prevented.
