Description

  The present invention relates to a medical image diagnostic apparatus such as an MRI (Magnetic Resonance Imaging) apparatus, and more particularly to a bed apparatus having a removable top plate to enable transfer of a subject from a transport vehicle to a bed. The present invention relates to a medical image diagnostic apparatus provided.

  In the conventional MRI apparatus, it is necessary to transfer the subject from a transport vehicle such as a stretcher to a bed in order to carry the subject into the imaging space, which is a burden on the subject and the operator. Therefore, in order to eliminate the transfer of the subject, a transport vehicle and a bed that can transfer the top plate on which the subject is placed from the transport vehicle to the bed have been proposed. For example, in the following document, a transport vehicle is installed on a side surface of a bed for handing over the subject, and the subject is handed over to the bed by sliding the top plate from the transport vehicle to the bed with a deployed support arm.

JP 2002-325763 A

  However, in Patent Document 1, the support arm for sliding the top plate is put in and out, and the top plate slid from the support arm is lifted and held by the support bar, and then lowered and fixed to the bed. The procedure for transferring the subject can be complicated.

  Accordingly, an object of the present invention is to provide a bed apparatus and a transport vehicle that can be easily transferred to a bed by sliding the top board from the transport vehicle.

In order to achieve the above object, in a medical image diagnostic apparatus including a top plate on which a subject is placed and a bed device on which the top plate is detachably mounted,
The couch device has a connecting portion with a transport vehicle for receiving the couch and carrying in and out of the subject, and the couch slides from the transport vehicle to the couch device or vice versa. The carrier vehicle has a running surface on which the couch device and the top plate slide from the carrier vehicle.

  According to the medical image diagnostic apparatus of the present invention, the top plate on which the subject is placed is slid from the carriage to the bed or vice versa, so that the subject can be easily transferred between the bed and the carriage. it can.

  Hereinafter, a preferred embodiment of a medical image diagnostic apparatus of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment of the invention, and the repetitive description thereof is omitted.

<First embodiment>
An overall outline of an example of the first embodiment to which the present invention is applied will be described. FIG. 1 shows an MRI apparatus 1 which is an example of a medical image diagnostic apparatus provided with a bed 2. The bed 2 includes a top plate support plate 3 on which a removable top plate 4 can be placed. As shown in FIG. 2, the top plate support plate 3 includes a transport wheel 5, and the top plate 4 is transported to the imaging space in the MRI apparatus 1 or a bed by an electric feed mechanism 6 connected to the top plate support plate 3. Can be pulled back to 2. However, the feed mechanism 6 moves the top plate support plate 3 in a belt manner by a motor (not shown).

  As shown in FIG. 2, the transport vehicle 7 placed beside the bed 2 is composed of a support plate 8 and a column 9 for fixing it, and the column 9 is provided with traveling wheels 10. A top plate 4 can be installed on the support plate 8. The support plate 8 is provided with a travel plate 11. When the carriage 7 is placed next to the bed 2, the height is adjusted, and the traveling plate 11 that is usually oriented vertically is attached to the support plate 8 as shown in the cross-sectional view described below in FIG. On the other hand, when it is tilted horizontally and connected to the top plate support plate 3, it becomes a running surface for the top plate 4 to slide between the bed 2 and the transport vehicle 7. As an example of the connecting means, for example, a concave portion may be provided on the top plate support plate 3 and a convex portion provided at the tip of the traveling plate 11 may be inserted.

  Wheels 12 as shown in FIG. 3 are provided on the back surface of the top plate 4 so that the top plate 4 can be manually moved to the left and right. Thereby, the top plate 4 can run on the running surface connected to the top plate support plate 3, and the top plate 4 slides between the bed 2 and the transport vehicle 7, thereby enabling transfer. The wheel 12 provided on the top plate 4 may be a wheel that can rotate in all directions, such as a ball caster. The transferred top plate 4 may be fixed, for example, by fitting a wheel 12 of the top plate into a fixing groove 13 provided on the top plate support plate 3 as shown in FIG.

In a simple embodiment as shown in FIG. 2, in a medical image diagnostic apparatus including a top plate on which a subject is placed and a bed device on which the top plate is detachably mounted,
The couch device has a connecting portion with a transport vehicle for receiving the couch and carrying in and out of the subject, and the couch slides from the transport vehicle to the couch device or vice versa. The carrier vehicle has a running surface for sliding the couch device and the top plate from the carrier vehicle. Therefore, by connecting the traveling plate 11 provided in the support plate 8 that can be expanded to the left and right to the top plate support plate 3, the top plate 4 is slid left or right from the transport vehicle 7, and the top plate support plate 3 Can be placed.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. The difference from the first embodiment is that the top plate slid from the transport vehicle is directly connected to the bed, so that the top plate is not placed on the top plate support plate as in the first embodiment. The board can be transported to the shooting space. The bed apparatus of the present embodiment is basically the same as that of the first embodiment. Therefore, only different points will be described.

  An outline of this embodiment is shown in FIG. By connecting the traveling plate 11 provided in the transport vehicle 7 to the bed side portion 14, a traveling surface on which the top plate 4 slides is provided. The top plate 4 slid from the transport vehicle 7 is placed on a bed plate 15 and connected to an electric feed mechanism 16 provided in the bed 2 as shown in FIG. For example, the connecting means may be fixed by providing a concave portion on the top plate 4 and inserting a convex portion provided on the feed mechanism 16. As shown in FIG. 6, the back surface of the top plate 4 is provided with wheels such as a ball caster 17 that can rotate in all directions, and can be transported to the imaging space or pulled back to the bed 2 by the feed mechanism 16.
