Abstract

(57) [Summary] [Objective] The battery is not replaced at the ECG transmitter, and the battery is always replaced at a distance where the magnet cannot attract the battery. An ECG transmitter is attached near the opening of the gantry, a battery is detachably attached to the rear of the bed, and the ECG transmitter and the battery are connected by a cable.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an MRI device.

[0002]

[Prior Art]

 The signal of the electrocardiogram was used as a trigger signal for imaging of the MRI apparatus. In the wireless type of the electrocardiographic synchronizer (ECG device) used in the MRI device, the transmitter was brought into the MRI examination room with a battery attached and was installed near the opening on the front of the gantry. Then, the battery is replaced by opening the lid of the battery storage section under the transmitter.

[0003]

[Problems to be solved by the device]

 When the battery was replaced, the battery was made of a ferromagnetic material, so the battery could accidentally jump into the magnet through the gantry opening. As a result, the battery could hit and the patient could be injured.

It is an object of the present invention to solve the above problems and to provide a device that does not perform battery replacement at the ECG transmitter, but always replaces the battery at a distance where the magnet cannot be attracted to the battery. .

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned subject, the composition of the present invention is as follows. That is, the ECG transmitter is attached near the opening of the gantry, the battery is detachably attached to the back of the bed, and the ECG transmitter and the battery are connected by a cable.

[0006]

[Action]

 Since it is far away from the gantry magnet at the back of the bed, it does not stick to the magnet even if the battery is inadvertently released from the hand.

[0007]

【Example】

 An embodiment of the present invention will be described below based on an embodiment shown in the drawings.

In FIGS. 1 and 2, an ECG transmitter 3 is attached near the opening 1 a of the gantry 1, a battery 8 is detachably attached to the rear of the bed 2, and the ECG transmitter 3 and the battery 8 are attached to each other. It is connected by a cable 9.

That is, in FIG. 2, an opening 2 d is provided in a rear side wall of a hollow cover 2 b of a bed 2 composed of a top plate 2 a, a cover 2 b and a bellows 2 c, and a lid 4 is attached thereto via a hinge 5, One end of the lid 5 can be opened and closed by a set screw 6. A battery holder 7 is provided on the bottom of the cover 2b, and a battery 8 is removably loaded therein. A cable 9 is connected between the battery holder 7 and the transmitter 3 via a connector 9a.

Therefore, when replacing the battery 8, the set screw is loosened with a screwdriver, the lid 4 is opened, and the battery 8 is replaced. Since the rear of the bed 2 is far from the magnet of the gantry 1, even if the battery 8 is carelessly released from the hand, it will not be attracted to the magnet. Since it cannot be replaced without a tool such as a screwdriver, it is possible to prevent a patient or the like from opening the lid 4 and removing the battery 8 inadvertently.

FIG. 3 shows another embodiment, in which the battery storage case 10 is mounted on the outer lower surface of the rear portion of the cover 2b, the battery holder is provided therein, and the case 10 is provided with the lid 11 similar to the above. .

FIG. 4 shows still another embodiment, in which the lid 12 of the storage portion of the battery 8 is formed of a cylindrical body, and may be screwed into the case 10 by the screw on the outer peripheral surface thereof.

Instead of the set screw 6 of the lid 4, a key and a lock may be used. In short, a lock means such as a screw, a key, and a lock that cannot be easily opened is provided.

The present invention is not limited to the above-described embodiments and embodiments, and includes various modifications without departing from the spirit and scope of the utility model registration request.

[0015]

[Effect of the device]

 The configuration of the present invention can prevent an accident that the battery is attracted to the magnet of the gantry when the battery is replaced.
