DESCRIPTION:
BRIEF SUMMARY
CASSETTES IN RADIOGRAPHY
The present invention relates to an arrangement for supporting and positioning X-ray cassettes in the required position in radiography of patients confined to bed.
X-ray examination of an unconscious or seriously ill patient is a difficult and heavy task requiring the participation of several people. If, for example, the lungs are to be X-rayed, the patient first has to be lifted so that an X-ray cassette can be positioned under him. Then, the X-ray tubes of the mobile radiographic apparatus are positioned above the patient's chest and activated for a frontal picture, whereupon the patient is once again lifted, and the cassette is pulled out. In recent years, one has discovered that it is possible to facilitate this operation by positioning the cassette under the mattress, seeing that the mattress does not affect the picture quality to any appreciable extent, provided that the mattress is made of foam plastics or foam rubber. In most cases, the radiologist, in order to be able to make a correct diagnosis, also needs a side picture which may be even more difficult to take than the frontal picture. Since it is not possible simply to put the cassette next to the patient, which for example in pneumonography would mean that the back portion of the lung will not get into the picture because of the considerable divergence of the X-rays, the patient has to be lifted, which requires 4-5 people, and propped up with pillows. During this operation, one often has to be careful with life-sustaining flexible tubes and lines. The taking of side pictures is sometimes so difficult and risky for the patient, especially the cardiac infarction patient, that one has to refrain therefrom.
The object of the present invention is to provide an arrangement for facilitating all radiography of the above-mentioned type to such an extent that one person without effort can take all the necessary pictures without endangering the patient. This object is achieved by means of an arrangement comprising at least one holder with a base member and a cassette support extending upwardly therefrom, the base member being supported by the bedstead bottom, and the X-ray cassette being fixable standing on edge between the base member and the cassette support, and at least one lifting means adapted to be inserted between the bedstead bottom and a mattress thereon in order to raise the latter, so that an X-ray cassette is insertable in the space thus formed. The invention will be described in detail below, reference being had to the accompanying drawings showing an embodiment.
FIG. 1 is a perspective view of a holder and an X-ray cassette.
FIG. 2 is a view of the holder in FIG. 1, the cassette being shown in another position.
FIG. 3 illustrates the use of the holder in FIGS. 1 and 2 on a mattress or similar support.
FIG. 4 is a view similar to FIG. 3, the holder being placed on the mattress.
FIG. 5 is a view of another embodiment of the holder according to the invention.
FIG. 6 illustrates the use of the holder in FIG. 5.
FIG. 7 is a view similar to FIG. 6, illustrating the use of the holder in FIG. 5 together with supporting pillows.
FIG. 8 is a view of a lifting means included in the arrangement according to the invention.
FIG. 9 illustrates the insertion of the lifting means under the mattress.
FIG. 10 illustrates the use of the lifting means when an X-ray cassette is placed under the mattress.
FIG. 1 shows a cassette holder 10 forming part of the arrangement according to the invention, said holder having a base member 11 and a cassette support 12 extending upwardly therefrom. The base member 11 is in the form of a substantially rectangular wire frame, and the cassette support 12 is a double arm pivotably connected to one short side of the wire frame via a tubular member mounted thereon to which the double arm is welded. The cassette support 12 has at the end facing away from the base member 11 a resilient cord 16 with a hook 17 adjustably connected thereto. Said hook can be attached to the edge of the cassette 13 which, with
