Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) The present invention relates to a bed device used in the field of medical diagnosis, particularly to an improvement of a bed device equipped with an arm holding device. .

(Prior art) When taking a radiographic tomography (CT), a contrast agent is injected into the body of the subject (patient) lying on a bed top while the patient is being examined. be exposed. In this case, since the arm of the subject is selected as the injection site for the contrast medium, the bed apparatus is usually provided with an arm holding device for keeping the arm of the subject in the examination posture.

(Problems to be Solved by the Invention) However, in the conventional arm holding device, a handle-like member having a downward U-shape as shown in FIG. Because the structure was only provided at the side end), it was ergonomically difficult for the subject to hold the arm, and as a result, it caused unnecessary pain to the subject. I was invited. This pain is especially severe for subjects such as elderly patients and patients with weak muscles, and there are cases where the patient moves their arm due to the pain, resulting in an accident where the contrast agent syringe comes off. tended to occur. Therefore, the emergence of an improvement measure for this problem has been strongly desired.

The present invention has been made in view of this situation, and it is an object of the present invention to provide a novel medical bed device equipped with an arm holding device that does not cause pain to the subject.

[Configuration of the Invention (Means for Solving the Problems) The configuration of the present invention for achieving this object is to provide an arm section that holds the arm section of a subject lying on a bed top in the posture of an examination state. The holding device is configured as an armrest-shaped unit that can be placed on the side of the subject with the tip of its arm bent in the direction of the head. The reason is that it is installed so that it can be displaced.

(Function) The function of the present invention based on this configuration is that the arm holding unit, which has a structure that does not cause pain to the subject from an ergonomic point of view, is placed on the side of the bed top plate against the top plate. It can be installed arbitrarily.

(Example) Hereinafter, the present invention will be described in detail based on an illustrated embodiment.

1 to 3 are schematic diagrams of an embodiment of the medical bed device according to the present invention, in which P is the subject, A is the left arm of the subject, 1 is the stand of the CT apparatus, 2 is a medical bed device used for this, 3 is a bed that can be raised and lowered, 4 is a top plate,
5 is a mat for protecting the subject placed on the top plate 4, and 6 is a contrast agent injector.

Reference numeral 7 denotes an arm holding unit (also simply referred to as a unit) according to the present invention, which has a shape that allows it to be placed in a posture in which the tip of the arm A of the subject (the part beyond the elbow) is bent upward and toward the head;
That is, it has a shape and structure similar to an "armrest" as a whole, and is composed of a base 71, a holder 72, and two elevating members 73.

As shown in FIGS. 3 to 5, the base 71 has a curved plate shape that matches the curvature of the top plate 4 so that it can be fixed in a sandwich manner between the top plate 4 and the mat 5. A protrusion 71a is provided on the side of the elevating member 73, and the elevating member 73 is adapted to the holder 72 according to the body shape and size of the subject.
It has a structure that allows the height of the base to be adjusted, and is provided on the protrusion 71a of the base.

The height adjustment structure of this member 73 is shown in Fig. 7 (a).
A screw type structure consisting of a screw 81 and an operating nut 82 as shown in ＞, and a spring type structure consisting of a coil spring 83 and an appropriate fixing device (not shown) as shown in FIG. In addition, a gas spring type structure as shown in FIG. 8(C) consisting of a cylinder 84, a piston 85, and an appropriate gas pressure supply device (not shown) can be used.

In the embodiment with such a configuration, first, the base 71 of the unit 7 is inserted between the top plate 4 and the mat 5 from, for example, the left arm side of the subject, and the left arm A of the subject is inserted into the sixth
Place it on the holder 72 of the unit as shown. In this state, the outer 2 front side of the arm is in contact with the holder 72, and the shape of the arm A at this time is exactly the same as the shape of the arm when using a normal "armrest". The relationship is reversed.

In this state, the entire position of the unit 7 is changed and the height of the holder 72 is adjusted to create a posture of the arm A that does not cause pain to the subject P. In this case, the weight of the mat 5 and the subject P is applied onto the base 71 of the arm holding unit 7, so that the unit 7 is reliably fixed at its adjusted position.

After that, the contrast medium injection process begins, but since arm A is held in an ergonomically comfortable position, subject P can undergo examination work for a long time. Become.

Although one embodiment has been described above, the present invention is not limited thereto, and can be modified in various ways without departing from its spirit. For example, in the embodiment, only the holding of the left arm part is explained, but if the structure of the unit is made symmetrical, it can be used as it is for the right arm part, and holders are provided on both sides of the base.
If the distance between them is adjustable, it becomes possible to hold both arms at the same time. Further, if the holder is provided with a mechanism that can adjust the direction of inclination, it will be more convenient.

In general, the unit can also be constructed as an integral part of the patient protection mat.

[Effects of the Invention] As described above, when the present invention is used, it is possible to carry out medical work without imposing pain on the subject.
