In many cases, voice instructions may cause the left and right to be mistaken, such as when the subject is tense, and may delay the examination. Will be greatly reduced, which will contribute to speeding up the inspection.

The pressure sensor 323 provided in the handle 32 is for detecting that the subject is holding the handle 32, and a display 52 that is turned on by a detection signal from the pressure sensor 323 is used as a control device. 5 is provided. That is, when the subject grips the handle 32, the pressure sensor 323 detects the force and sends the detection signal to the control device 5. Since the control device 5 is provided with a display 52 that is turned on in response to a detection signal from the pressure sensor 323, the operator determines whether or not the subject is holding the handle 32 based on whether or not the display 52 is turned on. Judgment can be made.

The indicator 52 is provided for each of the pressure sensors 323 of both the grips 32, or is turned on in response to a signal indicating that both of the pressure sensors 323 are held at a predetermined strength. Also good. Furthermore, if the indicator 52 is lit in steps according to the strength of the detection signal, the operator can determine whether the grip is insufficient or firmly gripped, so the grip is insufficient. If there is, the user can be instructed to hold the handle 32 firmly. In addition, when the subject does not hold the handle 32 or the grip is weak, the operation of the bed apparatus 3 can be prohibited based on this signal to ensure safety. .

Next, a specific embodiment of the handle 32 provided on both sides of the top plate 31 will be described. 3 is a perspective view showing an embodiment of the handle 32, FIG. 3 (a) is a perspective view showing the front side of the handle 32, and FIG. 3 (b) is a perspective view showing the back side of the handle 32.

As described above in detail, according to the present invention, it is possible for the operator in the operation room to surely confirm whether or not the subject to be examined holds the handle 32 by the lighting state of the display 52. Usually, when an X-ray image is taken by an X-ray diagnostic apparatus, a subject placed along the longitudinal direction of the top 31 is instructed to hold the handle 32 firmly with both hands.
There is a case where the user does not hold or the grip is weak. If the bed apparatus 3 is tilted overlooking such a state, there is a risk that the subject falls from the bed apparatus 3.
The safety is greatly improved by operating the X-ray diagnostic apparatus while confirming the grip state of 2 on the operation room side.

Further, when photographing the digestive system, when the subject changes the body direction on the bed apparatus 3, one of the handle 32 and the arrows 332 and 333 of the footrest 33 are made to emit light to turn left. You will be able to convey instructions to turn or turn right. Therefore, the time required for X-ray imaging can be shortened, and the burden on the staff as well as the subject can be reduced. In addition, instructions can be sufficiently transmitted to patients who have hearing impairments.
