Description

[Detailed Description of the Invention] This invention relates to a medical bed device whose top plate can be tilted in the longitudinal direction and which can be raised and lowered.

BACKGROUND ART Conventionally, as a bed whose top plate can be tilted and which can be raised and lowered, there has been an X-ray television set or the like, in which an X-ray tube and a television camera are disposed facing each other on both sides of the top plate. However, in such a device, it is necessary to be able to precisely rotate the X-ray tube, the top plate, and the television camera through 360° while maintaining them at fixed relative positions, which results in a complicated and large-sized mechanism.
By the way, when inserting a catheter into a patient to diagnose circulatory systems such as the brain and cardiovascular system, the top plate on which the patient is placed should be tilted at a maximum of 10 to 20 degrees.
A bed that can be raised and lowered and has a simple structure is desirable.

This invention was made in view of the above circumstances, and the object is to provide a medical bed device with a simple structure that allows the top plate to be tilted and to be raised and lowered.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a top plate on which a patient is placed, 2 is a top support stand attached to the top plate 1, and the top plate 1 is connected to a first substrate via a rotation mechanism 3. 4, it is rotatably supported. The rotation mechanism 3 includes a pair of bearing plates 5 vertically disposed on a first base plate 4, a small gear 7 that is rotatably supported by the bearing plates 5 and rotationally driven by a rotation drive mechanism 6, and a small gear 7 that is rotatably driven by a rotation drive mechanism 6. A large gear 9 is fixed to the plate 1, rotatably supported by the bearing plate 5 via a pin 8, and meshes with the small gear 7. and the first substrate 4
is supported on a second substrate 11 via a moving mechanism 10, so that the top plate 1 can be moved in its width direction. This moving mechanism 10 is the first
rollers 12 are rotatably supported on both sides of the substrate 4, the load is supported by the rollers 12, and a guide rail 13 is provided in the center of the substrate 4, and a guide roller is pivotally supported on the second substrate 11. 14 as a guide. Then, the second
The main board 1 is moved through the lifting mechanism 15.
6 so that it can be raised and lowered freely. This elevating mechanism includes, for example, a base of the power cylinder 17 attached to the main body board 15, and a plunger of the power cylinder 17 attached to the second
A guide rail 20 has a roller 19 attached to the main substrate 16 and a roller 19 rotatably supported on the second substrate 11 via a box 18.
It is designed to be raised and lowered along the In addition, 21
is a bellows provided between the top plate and the first board 4,
22 is a cover of the lifting mechanism.

With such a configuration, a patient (not shown) is placed on the top plate 1 and the rotational drive mechanism 6 of the rotation mechanism 3 is rotated.
When driven, the rotational force is transmitted to the large gear 9 via the small gear 7, and the top plate 1 can be tilted in the longitudinal direction. Furthermore, when the top plate 1 is pushed in the width direction, the first substrate 4 is moved relative to the second substrate by the rollers 12, and the top plate 1 can be moved in the width direction. Further, by driving the power cylinder 17, the plunger is raised and lowered, and the top plate 1 can be raised and lowered.

Therefore, the operator operates the rotating mechanism 3, the moving mechanism 10, and the elevating mechanism 15 as appropriate to tilt the patient placed on the top plate 1 or move it in the width direction of the top plate 1. It can be raised and lowered and held in an appropriate position. Therefore, insertion of a catheter or the like can be performed easily and safely, and fluoroscopy, direct or indirect photography, etc. can be performed without moving the patient to another bed. In particular, if an X-ray imaging device such as a C-arm or G-arm device is used, imaging equivalent to that of a rolling top plate can be performed, and dynamic observation of the heart is also possible.

In the above embodiment, since a moving mechanism for moving the top plate in the width direction is provided, the operation is particularly easy.

As described in detail above, this invention has a simple configuration in which the top plate is tilted in the longitudinal direction and can be raised and lowered, making it possible to provide a medical bed device that is small, inexpensive, and easy to install. .
