JP2000342578A - Bed with low radiation absorption for x-ray magnified radioscopy photographing of attachable and detachable type - Google Patents

Abstract

PROBLEM TO BE SOLVED: To execute safe examination and medical treatment through the use of an existent device at the time of executing magnified radioscopy photographing by fixing an additional, integrally molded bed with low radiation absorption having a size equivalent to its photographing bed and a proper height when it is considered in advance that magnified photographing is required. SOLUTION: At the time of executing magnified radioscopy photographing, a bed 1 with low radiation absorption which can attachably and detachably be fitted to the bed part 4 of an existent X-ray radioscopy photographing table 5 is additionally provided. This bed 1 is made of polystyrene foam which has strength sufficient to support a human body, is large enough for examination and treatment of a patient in a lying state and has a height enabling magnified radioscopy photographing. In addition, an edge part is reinforced with plastic for preventing breakage and the whole bed is coated with a synthetic fabric having flameproofing, waterproof and antibacterial functions. This bed 1 is fixed by hanging a load binding device to a hanging hole 3 previously provided at the bed 4 and binding it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for fluoroscopic examination and fluoroscopic treatment in the field of medical equipment. In particular, when it is desired to obtain a fluoroscopic image or a photographic image by geometrically enlarging a microscopic injured part, use of a radiation-absorbing table which is safe for a patient and facilitates reproducibility as an image is used.

[0002]

2. Description of the Related Art In a medical institution which does not have a magnifying photographing device, which requires a large capital investment, when obtaining a magnified image, a general X-ray apparatus is used to obtain a geometrically magnified image. As a method in this case, the similarity of a triangle is applied by providing a distance between the subject and the film system in the positional relationship of X-ray focal point-subject-radiation low absorption table or empty table-film system. .

[0003]

When the subject is brought closer to the X-ray tube side than the imaging bed and the table is provided between them,
The subject becomes unstable depending on the height and size of the table, and the image becomes blurred. Further, there is a danger during the fluoroscopic treatment.

According to the present invention, when performing geometric magnification fluoroscopy, the radiation low absorption table used is increased in size.
The purpose is to obtain reproducible images while performing safe examinations and treatments using existing devices.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an X-ray fluoroscopy table having a size and an appropriate height which are the same as those of the imaging bed when it is necessary to perform magnified imaging in advance. The integrated low-absorption bed for radiation is attached and added.

The additional low-absorption bed is made of, for example, styrofoam, and it is desirable to form a large integrated bed in order to increase the strength of the additional bed.

If the Styrofoam bed is used as it is, the edges will be damaged when the patient moves, so the edges are reinforced with plastic or the like, and the entire additional bed is sterilized.
Covering with a synthetic cloth having waterproof and flameproofing ability can maintain cleanliness and prevent corrosion due to heat and chemicals.

[0008] Since the additional bed is lightweight, it may move depending on the behavior of the patient or the operator. Therefore, in order to link and interlock with the bed of the X-ray fluoroscopy table, for example, it is connected and fixed by a binding device.

[0009]

In general, an X-ray tube has two types of focal points, large and small, and a small focal point is used during fluoroscopy or when performing enlarged photographing of a part having a relatively thin subject. The smaller the focal spot, the smaller its size, the greater the theoretical geometric magnification.
What can easily be done is to keep the distance between the subject and the film system as far as possible. This distance can be kept constant by placing a styrofoam bed.

[0010] When performing examinations and treatments, the patient is laid down from the viewpoint of safety. However, it is safer and more natural to carry out examinations and treatments by placing the entire body on an additional bed than by placing a bed on a part of the body. Can be implemented.

The distance between the subject and the film system can be made larger by using an additional bed than by placing a table on a part of the body.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the drawings. In FIGS. 1 and 2, a large styrofoam bed 1 covered with a waterproof flameproof cloth is placed on a bed of an X-ray fluoroscopy table. One edge is made of plastic so that the shape of the styrofoam is maintained. The binding device 2 is previously hooked on the hanging hole 3 provided in the bed 4 of the X-ray fluoroscopy table 5, and the additional bed 1 is bound to the bed 4 and fixed.

[0013]

Since the present invention is configured as described above, it has the following effects.

[0014] By using a large integrally molded styrofoam, it is light enough to be carried by one person, but has sufficient safety and strength to carry a patient. X
Even if it is added to the bed of the fluoroscopy table, the mechanical operation is normal. In addition, since it has moderate softness and heat retention, it is more comfortable for the patient than sleeping directly on the bed of the X-ray fluoroscopy table.

By placing the entire body of the patient on the table, examinations and treatments can be performed naturally, which is safe.

Although a dedicated magnifying fluoroscopic apparatus for optically and mechanically enlarging is considerably expensive, the present invention can require the same sharpness and resolution while being inexpensive.
Even if it is damaged, it can be easily replaced at low cost.
