Abstract

PURPOSE:To make it possible to fit easily a placing stage to the height of a carrier vehicle with a different height even when it is not operated by a skilled person by providing a memory device memorizing an information on height, a command device commanding movement up and down and a transferring mechanism transferring up and down. CONSTITUTION:When an UP/DOWN SW 11 is pushed down by an operator, a command for rotating a motor 21 is output to a drive circuit 19 from a CPU 13 based on a command information output from the UP/DOWN SW 11. A drive command is output to the motor 21 from a drive circuit 19 which has received the command. The apex part of the motor 21 is rotated by the drive command and a subject placing stage 3 is moved up and down by the actions of a screw 23 and a linking mechanism 25. At the same time when the motor 21 is rotated, increment or decrement of an information kept in a register 17 is performed by means of a CPU 13. The subject placing stage 3 is moved up or down like this until it becomes to the same height as that of a wheelchair.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a subject mounting device used in an X-ray CT apparatus, a magnetic resonance apparatus, a nuclear medicine diagnostic apparatus, or the like.

(Prior Art) A patient placed on a subject mounting table used in an X-ray CT device, magnetic resonance device, or nuclear medicine diagnostic device is transported in a vehicle for transporting the sick and injured, such as a wheelchair or stretcher. It may come. In this case, in order to move the patient from the transport vehicle to the subject mounting table, the height of the subject mounting table must be adjusted to the height of the transport vehicle.

Conventionally, in order to match the height of the subject mounting table, experienced operators or their intuition had to be used to adjust the height. Additionally, the height of the stage was adjusted each time the patient was moved, depending on the height of the wheelchair or stretcher.

(Problem to be Solved by the Invention) However, for an inexperienced operator, it may be difficult to match the height of the mounting platform to the height of the transport vehicle, and time is wasted. Therefore, it takes time to move the patient to the mounting table, which puts a burden on the patient. Further, even for experienced operators, it is a troublesome task to adjust the height of the mounting table to match the height of the transport vehicle, which has a different height.

Therefore, this invention was made in view of the above-mentioned conventional circumstances, and its purpose is to enable a person who is not an expert to easily set up a loading platform at different heights of transportation vehicles. The object of the present invention is to provide a subject mounting device that can be adjusted.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention includes a storage means for storing predetermined height information of a subject mounting table, and a storage means for storing predetermined height information of a subject mounting table, an instruction means for instructing to move the subject mounting table up and down to the predetermined height; and an instruction means for moving the subject mounting table to a height set based on information stored in the storage means according to the instruction from the instruction means. It is composed of a moving mechanism that moves up and down.

(Function) In the above configuration, the present invention stores the height information of the vehicle for transporting the sick and injured in the storage means in advance. When the subject mounting table is located at an arbitrary height, the instruction means instructs the subject mounting table to be moved up and down to the height of the vehicle for transporting the sick and injured.

In response to this instruction, the moving mechanism moves the subject mounting table up and down to the height set based on the information stored in the storage means.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a configuration diagram showing an embodiment of the subject mounting apparatus of the present invention.

In the figure, the operation panel 1 includes a memory SW (switch) 5 for storing the height of the subject mounting table 3, and a memory SW (switch) 5 for issuing instructions to move the subject mounting table 3 up and down to the memorized height. A wheelchair SW7 and a stretcher SW9 are provided. The operation panel 1 also includes UP/DOWNSWI buttons for simply moving the subject mounting table 3 up and down.
1 is also provided.

The memory SW5 outputs instruction information for storing the height of a wheelchair (not shown) to the CPU (central processing unit) 13 when pressed at the same time as the wheelchair SW7.

Furthermore, when the memory SW5 is pressed together with the stretcher SW9, it outputs instruction information for storing the height of the stretcher (not shown) to the CPU 13.

When pressed individually, the wheelchair SW7 and stretcher SW9 output instruction information to the CPUI 3 to move the height of the subject mounting table 3 up and down to the height of the wheelchair or stretcher.

The CPU 3 controls the entire subject mounting apparatus of the present invention, and for example, based on the instruction information output from the memory SW5, the height information of the subject mounting table 3 is stored in the memory 15 or in the memory 15S. It is to be memorized. Further, the CPU 3 constantly provides height information to the register 17 every time the height of the subject mounting table 3 changes.

Furthermore, CPUI3 supports wheelchair SW7, stretch +

11, the motor 21 is driven via the drive circuit 19 based on the instruction information output from the motor 11.

The memory 15 and the memory 15S each store height information of a wheelchair or a stretcher.

The register 17 has an information value of "0°" when the subject stage 3 is at its lowest position, and always holds the current height information of the subject stage 3 (for example, the number of rotations of the motor 21). It is.

The motor 21 rotates its tip in response to a drive command from the drive circuit 19, and rotates the screw 23 and link mechanism 25.
The subject mounting table 3 is moved up and down via the .

An embodiment of the present invention is constructed in this manner.Next, the operation of the present invention will be described with respect to the case where the height is adjusted to the height of the wheelchair.

When the operator presses UP/DOWNSWI 1, the CPU 13 issues an instruction to the drive circuit 19 to rotate the motor 21 based on the instruction information output from the UP/DOWNSWI 1. Upon receiving this instruction, the drive circuit 19 outputs a drive command to the motor 21 . With this drive command, the motor 21
is rotated, and the subject mounting table 3 is moved up and down by the action of the screw 23 and the link mechanism 25. At this time, simultaneously with the rotation of the motor 21, the information held in the register 17 is incremented or decremented by the CPU 1B.

In this way, the subject mounting table 3 is moved up and down until it is at the same height as the wheelchair.

When the subject mounting table 3 is set at the same height as the wheelchair,
Press memory SW5 and wheelchair SW7 at the same time. As a result, the storage instruction signal 101 is output to the CPU 13.

The CPU 1B manually inputs this storage instruction signal 101.
The height information of the subject mounting table 3 that is the same as the wheelchair, which is held in the register 17, is copied to the memory 15K.

UP/DOWNSWI 1+: Therefore, if it becomes necessary to move the subject mounting table 3 to the height of the wheelchair when it is located at an arbitrary height, only the wheelchair SW7 Press . As a result, movement instruction signal 1
03 is output and manually input to CPU13.

Upon receiving the movement instruction signal 103, the CPU 13 compares the current height information of the subject mounting table 3 held in the register 17 with the height information of the wheelchair stored in the memory 15K. In this comparison result, register 17
If there is a difference between the information in the memory 15 and the information in the memory 15, the CPU 13 issues a rotation instruction to the drive circuit 19 to reduce this difference. Further, the drive circuit 19 outputs a drive command according to this rotation instruction, and this command causes the motor 21 to rotate, and the subject mounting table 3 moves so as to approach the height of the wheelchair.

At the same time as the motor 21 rotates, the information in the register 17 is updated by the CPU 13, and the updated register 17 is updated.
The information in the memory 15 is constantly compared with the information in the memory 15.

When the information in the register 17 and the information in the memory 15 become equal, the rotation instruction being output from the CPU 13 is stopped. Thereby, the subject mounting table 3 is stopped at the same height as the wheelchair.

In this way, by first storing the height of the wheelchair in the memory 15K, if you want to move the subject mounting table 3 to the height of the wheelchair again, just press the wheelchair SW7 and it will automatically move. The subject mounting table 3 can be moved to that height.

In this embodiment, a case has been described in which the height is adjusted to the height of the wheelchair, but of course it is also possible to adjust the height to the height of the stretcher. It is also possible to provide a plurality of SWs to match a plurality of desired heights.

The operation panel 1 may be set at a desired location, such as on the side of the subject mounting table 3, at a slightly distant side, in front of the gantry, or on the console, and is not limited to a specific location.

[Effects of the Invention] As explained above, the subject mounting device according to the present invention allows even non-experienced operators to adjust the height of transport vehicles such as wheelchairs and stretchers in a short period of time. The subject mounting table can be easily adjusted. Therefore, the burden on the patient can be reduced. Further, it becomes possible to eliminate the troublesome work of setting the vehicle at different heights of transportation vehicles each time.
