Medical bed apparatus
View Patent ↗A medical bed apparatus of an embodiment includes: a tiltable top board on which to place an examinee; a photographic mechanism configured to radiograph the examinee; an operation unit which is provided to a lateral side of the top board, and through which at least one of the top board and the photographic mechanism is operated by an operator; and a horizontally-holding mechanism configured to hold the operation unit horizontally when the top board tilts.
1. A medical bed apparatus comprising:
a tiltable top board on which to place an examinee;
a photographic mechanism configured to radiograph the examinee;
an operation unit which is provided to a lateral side of the top board, and through which at least one of the top board and the photographic mechanism is operated by an operator; and
a horizontally-holding mechanism configured to hold the operation unit horizontally when the top board tilts, wherein
the horizontally-holding mechanism comprises:
an angle sensor configured to detect a tilt direction and a tilt angle of the top board; and
a driving unit configured to drive the operation unit to offset the tilt of the operation unit in accordance with the tilt direction and the tilt angle of the top board which are detected by the angle sensor.
2. The medical bed apparatus of claim 1 , wherein
the driving unit is a spherical piezoelectric motor interposed between the top board and the operation unit.
3. A medical bed apparatus comprising:
a tiltable top board on which to place an examinee;
a photographic mechanism configured to radiograph the examinee;
an operation unit which is provided to a lateral side of the top board, and through which at least one of the top board and the photographic mechanism is operated by an operator; and
a horizontally-holding mechanism configured to hold the operation unit horizontally when the top board tilts, wherein
the horizontally-holding mechanism is formed to allow the operator to tilt the operation unit relative to the top board, and
the horizontally-holding mechanism is formed to switch a tilt operation of the operation unit relative to the top board between its fixation and release in response to an operator's manipulation of the operation unit.
4. A medical bed apparatus comprising:
a tiltable top board on which to place an examinee;
a plurality of expandable and contractible legs provided to the top board;
a horizontally-holding mechanism configured to hold the table horizontally when the top board tilts, wherein
the horizontally-holding mechanism comprises:
an angle sensor configured to detect a tilt direction and a tilt angle of the top board; and
a driving unit configured to expand, contract and drive the plurality of legs to offset the tilt of the table in accordance with the tilt direction and the tilt angle of the top board detected by the angle sensor.
5. The medical bed apparatus of claim 4 , wherein
the driving unit comprises a plurality of spherical piezoelectric motors interposed between the top board and the plurality of legs.
6. The medical bed apparatus of claim 4 , wherein
the top board is formed tiltable in at least longitudinal and lateral directions.
7. The medical bed apparatus of claim 4 , wherein
the horizontally-holding mechanism is formed to allow the operator to tilt the table relative to the top board.
8. A medical bed apparatus comprising:
a tiltable top board on which to place an examinee;
a plurality of expandable and contractible legs provided to the top board;
a table horizontally supported by the plurality of legs; and
a horizontally-holding mechanism configured to hold the table horizontally when the top board tilts, wherein
the horizontally-holding mechanism is formed to allow the operator to tilt the table relative to the top board, and
the horizontally-holding mechanism is formed to switch a tilt operation of the table relative to the top board between its fixation and release in response to an operator's manipulation of the operation unit.
