Abstract
Abstract In an exemplary embodiment, a patient support platform, resting on a frame, can be irradiated in a shadow-free fashion, and is provided with two longitudinally extending support rails for the mounting of accessories, and a collector basin for collecting outflowing contrast medium. To avoid grooves and cracks where fluids can accumulate and make cleaning very difficult, a single-piece, smooth support plate is provided for entirely covering the upper surface and the four lateral edges--adjoining the upper surface--of the patient support platform, and the support rails are moved to the longitudinal sides of the support plate. In addition, the support plate can be provided with a flat depression with marginal edges extending at a shallow angle for minimized attenuation of incident X-rays. The support rails can manifest a T-shaped cross section and can be mounted with the foot of the "T" on the drawn-down lateral edges of the examination table.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
99 words
An examination table for a urological X-ray examination apparatus comprising a patient support platform capable of shadow-free irradiation, resting on a frame, comprising two longitudinally extending support rails for the mounting of accessories, and comprising means for collecting contrast medium flowing out, characterized in that there is mounted on the patient support platform (7) a single-piece, smooth, support plate (8) with support rails (15, 16) attached to the longitudinal sides (13, 14), said support plate consisting of readily disinfectible material, completely covering the upper surface and the four lateral edges of the patient support platform adjoining the upper surface.
Claim 2
Dependent Claim
99 words
An examination table for a urological X-ray examination apparatus comprising a patient support platform capable of shadow-free irradiation, resting on a frame, comprising two longitudinally extending support rails for the mounting of accessories, and comprising means for collecting contrast medium flowing out, characterized in that there is mounted on the patient support platform (7) a single-piece, smooth, support plate (8) with support rails (15, 16) attached to the longitudinal sides (13, 14), said support plate consisting of readily disinfectible material, completely covering the upper surface and the four lateral edges of the patient support platform adjoining the upper surface.
Claim 3
Dependent Claim
40 words
An examination table according to claim 1, characterized in that the support plate (8) is provided, in the region of the posterior of the patient, with a flat, 1 to 50 mm-deep depression (9) which is flat at its edges.
Claim 4
Dependent Claim
33 words
An examination table according to claim 2, characterized in that the depression is provided with a discharge port (11) in the region of the caudal frontal side (10) of the support plate (8).
Claim 5
Dependent Claim
96 words
An examination table according to claim 1, with the support rails (15, 16) having a T-shaped cross section, each support rail including an elongated foot portion secured with a respective lateral edge (8a, FIG. 2) of the support plate (8), said lateral edges of the support plate covering the edge of the patient support platform (7) and the frame (17) of the examination table (3), the support rails (15, 16) being fastened through the support plate (8) with the frame (17) of the examination table (3), and the frame (17) bearing the patient support platform (7).
Claim 6
Dependent Claim
39 words

Dependent Claim
96 words
An examination table according to claim 4, characterized in that the foot section (19) of accessory holders (18), which are capable of being slipped over the support rails (15, 16), has a C-shaped cross section, and, for the purpose of locally-independent fitting onto the support rails (15, 16), is milled out in the width of the rail head on the slotted sides, at mutually opposite ends, and on oppositely disposed sides of the slot, at an angle α of approximately 30°, and that it is provided with a clamping device (20) for engaging the support rails.
Claim 8
Dependent Claim
31 words
