DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a table intended for being used to carry out rest and exercise echocardiographic examinations.
Usual echocardiographic tables comprise a horizontal couch mounted on a structure fitted with casters and a crank gear fixed to the couch and which the patient sets in motion with his legs for exercise echocardiographic examinations. As the patient lies horizontally on his back, the movement of his legs must be done in uncomfortable conditions and it is necessary to provide for additional accessories in order to ensure the immobilization of the patient's thorax.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a compact table requiring minimum space and making it possible to carry out both rest and exercise examinations in maximum conditions of comfort while ensuring a great stability of the patient's thorax and thus a persistence of the quality of the echocardiographic image during the exercise.
More particularly, the couch is attached to a frame mounted on sliding-blocks arranged to slide lengthwise on a carrying chassis fixed to a support structure. The couch is comprised of a back and a seat attached so as to be capable of pivoting on a hinge axis fixed to the frame. The back and the seat are connected to means fixed to the carrying chassis in order to adjust the back and the seat inclines. The carrying chassis is mounted at its ends on two supporting columns so as to be rotatable on a longitudinal pivot axis. The crank gear is attached to the carrying chassis and it can be connected to a driving device for the control of the height thereof in relation to the carrying chassis.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in the drawings, the couch 10 of the examination table according to the invention is comprised of a back 11 and a seat 12 connected by a hinge 13 that allows the back 11 on the one hand and the seat 12 on the other hand to be inclined separately. Hinge 13 is fixed to a metallic frame 14 mounted on sliding-blocks capable of sliding on two parallel rails 15 fixed to the longitudinal sides of a carrying chassis 16. When the frame 14 moves along rails 15, the back 11 and the seat 12 move in a front back movement in relation to the chassis. Jacks 17 and 18 are fixed to frame 14 for the control of the individual inclinations of the back 11 and the seat 12 respectively.
To the carrying chassis 16 there is also attached a fork 19 carrying a crank gear 20 which is thereby movable together with the chassis during its lateral revolving movement. The crank gear 20 is connected to a jack 21 which permits the crank gear to be moved independently in an upward and adjustable movement relative to the chassis 16. The crank gear is advantageously connected to an electronic device 25 arranged to perform programmes of progressive difficulty in order to graduate the efforts to be made by the patient.
Carrying chassis 16 is comprised of longitudinal girders linked at their ends by transverse girders. These are fixed in their middle portion to two supporting columns 26 so as to be capable of revolving on a longitudinal pivot axis 100, whereby the chassis moves the back 11 and the seat 12 in a lateral revolving movement on the anterio-posterior axis of the table (see FIG. 3). The rotation of the chassis on the anterio-posterior axis mentioned above is controlled by jack 27 connected between the chassis 16 and the table support structure 28.
The supporting columns 26 are fixed to the
