Description

According to the present invention, the subject can be placed on the mobile bed apparatus, moved from the hospital room to the examination room , imaged without changing to the bed apparatus, and returned to the hospital room again. And the load on the subject and the medical staff can be reduced. Furthermore, by driving the lifting / lowering device with a battery provided in the movable bed apparatus, the movable bed apparatus can be moved up and down even in a state where it is separated from the medical imaging apparatus, and the load on the medical staff accompanying the lifting / lowering operation can be reduced. Can be reduced.

The uppermost position and the lowermost position of the upper base 10 are determined by the relationship with the imaging space position of the MRI apparatus connecting the movable bed apparatus 1, and the uppermost position conveys the top plate 11 into the imaging space. Thus, the lowest position is determined by the mechanical position when the punter arm 30p is most contracted. Desirably, the height is set so that the subject 2 can move easily when getting on and off the table 11.

A switch 53 is provided between the AC connector 52 of the bed side connection connector 50 and the charger 83. The switch 53 is electrically connected to the PCB 81. The switch 53 is normally OFF, and the AC connector 52 and the charger 83 are disconnected. As a result of monitoring the battery 82, the PCB 81 switches the switch 53 to ON when it is determined that the remaining battery level is less than or equal to the threshold value and charging is necessary. A signal for switching the switch 53 to ON is indicated by 95 in the figure. Thereby, the AC connector 52 and the charger 83 are brought into conduction, and the battery 82 is charged from the charger 83 using the AC power supplied from the MRI apparatus 200. 9 to 14, the switches 53, 54, and 55 are depicted separately from the PCB 81. However, the switches 53, 54, and 55 may be provided on the circuit board of the PCB 81. The locations of 54 and 55 can be changed in design without departing from the spirit of the present invention.

As shown in FIG. 23, at the longitudinal end of the upper base 10 of the movable bed apparatus 1c, the handle 100 that the operator holds when moving the movable bed apparatus 1c and the wheels 42 for driving the motor are motorized. A driving device (described as “M” in FIG. 22) 101, a brake mechanism (described as “BK” in FIG. 22) 102 for braking the movable bed apparatus 1c, and a brake (not illustrated) provided in the handle 100 A handle and a brake wire 103 that connects the brake mechanism 102 are provided. When the operator grasps and pushes the handle 100, the load on the wheel 42 (and the wheel 44 positioned opposite to the wheel 42 across the longitudinal axis of the lower base 21) is detected, and the driving device 101 is detected. Wheel drives the wheels 42 and 44 from the DC power supplied from the battery 82. The wheels 41 and 43 follow the wheels 42 and 44.
