Abstract
Abstract The invention relates to a patient support for diagnostic apparatus, notably for an MRI apparatus, comprising a stretcher on which a patient can be arranged so as to be introduced into the diagnostic zone of the apparatus, the support comprising a core of a fiber-reinforced epoxy resin with a coating provided thereon, the core being made of a fiberglass-reinforced synthetic material on an epoxy resin basis with an isotropic fiberglass structure wherethrough cavities extend in the longitudinal direction, which cavities are filled with a fiber glass fleece impregnated with epoxy resin, the upper side being provided with a fiber-reinforced coating on an epoxy resin basis with unidirectional fibers of a synthetic material of a high tensile strength.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A patient support for a diagnostic apparatus, notably for an MRI apparatus, comprising a cantilevered stretcher to support an object to be examined and to be introduced into an examination zone of the apparatus, the support comprising a core of fibre-reinforced epoxy resin provided with a coating, characterized in that the core is made of a fibreglass-reinforced synthetic material on an epoxy resin basis with an isotropic fibreglass structure wherethrough cavities extend in a longitudinal direction of the stretcher, which cavities are filled with a fibreglass fleece impregnated with epoxy resin, an upper side of the stretcher being provided with a fibre-reinforced coating of a synthetic material on an epoxy resin basis with unidirectional fibres of a synthetic material of high tensile strength.
Claim 2
Dependent Claim
123 words
A patient support for a diagnostic apparatus, notably for an MRI apparatus, comprising a cantilevered stretcher to support an object to be examined and to be introduced into an examination zone of the apparatus, the support comprising a core of fibre-reinforced epoxy resin provided with a coating, characterized in that the core is made of a fibreglass-reinforced synthetic material on an epoxy resin basis with an isotropic fibreglass structure wherethrough cavities extend in a longitudinal direction of the stretcher, which cavities are filled with a fibreglass fleece impregnated with epoxy resin, an upper side of the stretcher being provided with a fibre-reinforced coating of a synthetic material on an epoxy resin basis with unidirectional fibres of a synthetic material of high tensile strength.
Claim 3
Dependent Claim
34 words
A patient support as claimed in claim 1, characterized in that the fibreglass-reinforced epoxy resin material of the core includes a fibreglass fabric whose modulus of elasticity amounts to approximately 15,000 N/mm 2 .
Claim 4
Dependent Claim
36 words
A patient support as claimed in claim 1, characterized in that the unidirectional fibres of synthetic material of the upper coating have a high tensile strength and modulus of elasticity of approximately 30,000 N/mm 2 .
Claim 5
Dependent Claim
36 words
A patient support as claimed in claim 1, characterized in that the fibreglass fleece impregnated with epoxy resin has a density below about 700 kg/m 3 and a compressive strength above about 200 N/mm 2 .
Claim 6
Dependent Claim
33 words
A patient support as claimed in claim 1, characterized in that the cavities are separated from one another in the longitudinal direction by means of vertical partitions which also increase the stretcher rigidity.
Claim 7
Dependent Claim
34 words
A patient support as claimed in claim 1, characterized in that the support includes a carriage part which carries the stretcher, the carriage being provided with rolling devices at a pair of longitudinal sides.
