Bergen County, N. J., assignor to Smith-Chapman, Inc, Irvington, N. J.., a corporation of New Jersey Application September 9, 1950, Serial No. 184,699
(or. :25il-F50') 11 Claims.
This invention relates to X-ray, fluoroscopic and similar apparatus for photographin and viewing internal body structure. It has been found, in practice, that it is extremely difiicult to make X-ray and fluoroscope examinations of infants, particularly those ranging in age from newborns to the age of sitting-up. Such infants are extremely unstable in their body movements and have presented a serious problem to physicians and nurses desiring to take internal radiographic and/or fluoroscopic views of the thymus. chest, skull, spine, abdomen, etc.
The device of this invention is designed to enable the immobilization of such infants for the purpose mentioned in a manner which will materially reduce the amount of time required for positioning an infant, and will substantially simplify the procedure.
These and other advantageous objects, which will appear from the drawings and from the description hereinafter, are accomplished by the structure of my invention, of which an embodiment is illustrated in the drawings. It will be apparent, from a consideration of said drawings and the following descriptiomthat the invention may be embodied in other forms suggested thereby, and such other forms as come within the scope of the appended claims are to be considered within the scope and purview of the instant invention.
In the drawings;
Fig. 1 is a perspective view of a device embodying the invention, showing the seat block thereof in dotted lines in the position it would occupy in the use of the device, and in full lines removed from the device but in position for insertion in the supporting plate of the device,
Fig. 2 is a side elevational view of the device shown in Fig. '1, with the seat block shown positioned therein and showing, in dotted lines, the cassette holder of the device in pivoted position relative to the plane of the upright supporting bar of the device,
Fig. 3 is a front elevational view taken on line 33 of Fig. 2, and showing, in dotted lines, a lower position to which the seat block may be moved, v
Fig. 4 is a fragmentary'perspective view, taken on line 44 of Fig. 3,
Fig. 5 is a perspective view of thecrotch member used in carrying out the invention,
Fig. 6 is an exploded perspective view of a form of seat supporting plate, and a means to engage the same and the bar for positioning the former on the latter relative to the cassette holder,
Fig. '7 is a perspective view of a seat block bodying the invention, and
Fi 8 is an enlarged side elevational view of the seat supporting plate shown positioned on the bar, which is indicated fragmenta'rily and in dotted lines.
The drawings illustrate a device for positionin and immobilizing infants embodying the invention in a practical form. It will be apparent that variations may be made in View of the disclosure of the drawings and the following descrip tion. Such variations and modifications are as comprehended "in the scope of the appended claims are to be deemed within the purview of the instant invention.
The device shown in the drawings comprises an elongated upright supporting bar l0 provided with an axial slot H and a cassette'holder 12 secured to said bar and comprising a bottom wall 13 and side walls l4, l5, and meanssuch as bolts 16, I6 passing through slots H, I1 in the bottom wall I3 to adjustably secure the side walls there to. Thus, the side walls may be moved toward and away from each other to accommodate X-ray cassettes of various widths. A seat supporting plate 18 is adapted to be secured to the bar ill in a position which may be predetermined by the user of the device relative to the cassette holder 12 to accommodate infants of various heights and to position the desired body portion in alignment with the cassette holder. A seat block 9 is provided for the seating of the infant, said {block having side walls '20, 21, and end walls 22, 2mm a portion 24 angularly disposed relative to the longitudinal axis of the seat block at one of the end walls thereof. The seat block is provided with means such as keys 25, 25a, 25b, on one or more of the side and end walls and on the angular portion thereof to have complementary engagement with the keyway 25 of the plate I8. The cross sections of the keys and keyways are com-' plementary so as to permit the block 19- to be slid into position on the seat supporting plate. For that purpose, the keys may be of T-shaped cross-section and the keyways of C-shaped crosssection (Figs. 4 and 6). The seat block is provided with an internal opening 38, through which the legs of the infant seated on the block may be positioned. To further assist the positioning of the infant, a crotch member 3| (Figs. 5 and 1). is provided, said crotch member having opposite ends 32, 33, of' an outlin complementary to the inner faces of the side walls 20, 2| of the block which define the internal opening thereof. By this arrangement, the crotch member may be slid 3 along the Side walls toward or away from an end wall of the block to position the infant at pre cisely the point desired.
As above noted, the seat supporting plate I8 is adapted to be vertically moved relative to the cassette to thereby fix the position of the seat block on the device; any suitable means engaging the supporting plate l8 and bar H3 may be used to that end. As shown in Fig. 6 (one of many forms useful for the purpose), the supporting plate is provided with a stud 34 fixed at one end to said plate [8 and passing through the slot l l of the bar l0 and projecting therebeyond. The
projecting end 35 of the stud may engage or be engaged by any suitable means to hold the same at the selected position on the bar, as, for ex-,
ample, by providing the stud with threads engaged by the nut member 36 (Figs 6 and 8).
The cassette holder l2 may be rigidly fixed to the bar, or, as shown in Figs. 1, 2 and 4, may be pivotally secured thereto as indicated at, 31 (Fig.
2), in which case the cassette holder and bar are provided with means to hold the cassette holder in alignment with the bar, as indicated in Fig. 2 in full lines, or to selectively hold the same in pivoted position at a predetermined angle 38 thereto, as shown in dotted lines in Fig. 2, or at other selected positions. To this end, the cassette holder and bar may be provided with interengaging means for use by the operator, as, for example, the arms 39, 40 fixed to the cassette holder, and a long pin passed through both arms and bearings 43, 44, or short pins 4| passing through slots 42 in the bearings 43, 44 fixed to the bar and through the arms 39, 40, said pins being engaged by nut members 46 or the like to thus fix the position of the cassette holder relative to the plane of the bar ID. This feature of pivotal movement of the cassette holder may be provided for the purpose of enabling an angular disposition of the head, for example, of the patient, where that is desirable for special purposes. The device may be further provided with a flexible band 41 having an end 48 fixed to a side wall, as, for example, wall I 5 of the cassette holder by any suitable means, such as the bar 49, and having a free end 50 which may be drawn taut on to the other side wall I 4 of the cassette holder, as, for example, by a winding device 5| or the like. The band will hold the part to be X-rayed close to or in contact with the cassette.
From the foregoing, it will be noted that the seat block l9 may be raised or lowered in relation to the cassette holder and may also be positioned at any angle in relation to the cassette holder for posterior, anterior, lateral or oblique views.
The bar Ill may be secured to an X-ray table, wall, fioor or other device in any desired or convenient manner.
