FR2523433A1 - Swivelling support for examination of chilo on radiology table - has fixed frame with height and rotation adjustable and lockable board - Google Patents

Abstract

The support consists of a fixed structure (1) having two triangular symmetric sides (1 1, 1 2) joined two by two at their base ends to lateral side-frames (1 3) with swivelling blocks and external control levers (4) for engaging them in profiled slats in the examination table and bolting them after rotation. The upper angles formed by adjacent branches of the triangular sides allow height fixing by cylindrical sleeves (1 4, - 1 5) in which slide support tubes (6-6 1) which can be locked in height adjustable position. The lower ends of the support tubes allow free axial articulation and locking in position of a longitudinal axial board (7) on which the child lies for medical examination in all positions. The orientation of the board is obtained by an electric motor acting either directly on its support axis joining the tubes, or indirectly by the intermediary of a friction drive.

Description

 The present invention relates to medical sciences, in particular radiology devices.

 In known devices of this kind, in particular X-ray diagnostic devices, infants lying on the examination table must be immobilized and positioned relative to the radiology head during all operational time.

 This holding and positioning is carried out manually by a manipulator, with great difficulty in obtaining the perfect stillness necessary for the sharpness of the image.

 In addition, the dangers from X-rays oblige radiology manipulators to observe very strict safety rules to avoid serious radiodermatitis, which can be detected in the long run.

 It is therefore in order to overcome these drawbacks that it appeared necessary to produce an adjustable support adaptable to a radiology table, which is the subject of the invention.

 According to one characteristic, this orientable support is established with a frame forming two longitudinal members with means of attachment to the support table of the radiology device and extreme uprights for axially supporting the vertical sheaths with height adjustment device and circular orientation of an axial and longitudinal board on which the child to be examined is extended and held in strips.

 Figure 7 is a partial perspective view illustrating the means of fixing the support on the examination table of the radiology device.

 This adjustable support adaptable to a radiology table is established essentially according to the nonlimiting example illustrated by the drawing, with a framework (1) forming two symmetrical triangular sides (11 - 12) connected in pairs by their free lower ends, by side rails (13) arranged along the spacing of the profiled grooves (21) of said examination table (2).

 Cleats (3) fixed below each beam (13) engage freely and respectively in each groove (21), to orient themselves angularly and perpendicularly in the locked position, by means of an external lever (4) externally mounted on the pivot axis (5). These cleats (3) thus allow the positioning and maintenance of the frame (1) on the table (2).

 The upper angle formed by the adjacent branches of each side (11 or 12) also allows the fixing in elevation of a vertical and axial sheath (14 - 1) in which slides and locks in height a support tube (6 - 61).

 An axial board (7) coupled to articulation, with locking means, connects the lower ends of the support tubes (6 - 61), so as to receive the extended child held by bands, straps or otherwise.

 For this purpose, each vertical sleeve (14 - 15) is made (8) integral at its end with a housing / in which is mounted with transverse sliding a movable head (9) centered very freely by its bore on the periphery of the support tube (6 or 61) which also slides in said housing (8).

 A tightening handle (10) forming a nut, takes facial support on the housing (8) and is screwed onto the external and projecting threaded rod (91) of the head (9), so as to allow its slight transverse sliding in view of the tightening of the support tube (6 or 61) after the height adjustment of the axial board (7).

 The lower and circular end of one of the support tubes (6 or 61) receives a transverse and circular tab (11), externally forming, on the board side (7), prominent teeth (111) arranged radially with respect to an opening axial allowing the engagement of a locking screw (12).

 The teeth (111) cooperate in superposition with the complementary teeth (131) of a movable tab (13), allowing the screwing of the screw (12), and perpendicularly supporting the end of the board 7).

 It will be appreciated that after the screw (12) has been released, the teeth (111 and 131) can escape in view of the circular orientation of the board (7) around the screw (12) forming an axis, depending on the position required. The blocking of the screw (12) authorizes the engagement of said teeth (111 - 131) for blocking after adjustment.

 On the opposite side, the tube (6) allows the attachment of a guide means, such as a collar ring (14) enclosing a ball bearing (15) to support an overhanging axis (16) integral with the end corresponding from Plate 7).

 According to these provisions, it can be understood that after the support and the support on the table have been put in place and locked (2), the child is stretched out on the axial board (7) abutting with his feet on a transverse cleat (71) , while which bands (17) preferably self-gripping and links (18) keep his body, legs and arms in an extended position.

 The board (7) is moved vertically and locked by the handles (10) acting on the support tubes (6 - 61), for its height adjustment with respect to the radiology head. This movement also allows the rotation of the board (7) around the axis (16), after release of the screw (12), with a view to its orientation and blocking, to carry out medical examinations in all positions, from the facial position to the child's back position.

 It is obvious that without departing from the scope of the invention, the orientable board (7) can be controlled in its rotational movements by an iectric motor acting either directly on its support axis connecting the tubes (6 - 61), or through a friction drive.

 The advantages of this orientable support emerge clearly from the description. We underline in particular - The immobility of the child causing perfect clarity of the image.

picture.

- The possibility of orientation of the extended child, in all directions to facilitate the medical examination.

- The perfect safety of the manipulator which is thus far from the dangerous X-ray protection zone.

- The possibility of use from the age of a newborn to the age of a small child.

- The possibility of a vertical orientable positioning in the case of radiology devices forcing the patient to occupy this position.

 The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary, it embraces all its variants.
