Title: Contrast prod syringe adaptor - for use on abdominal compression diagnosis table
IPC: A61B6/04
Filed: 1972-09-29
Abstract: Automatic injection device is for use with a contrast prod. contained in plastic or metallic syringes. It comprises a table with two perforations for the introduction of the ends of the syringes. A bracket has two collars, each of which is provided with two screws so that their dias. can be varied. The bracket has a hinge and, when folded back over the syringes, is held against a plate by a magnet. Two cramps are provided for fixing the arms carrying the compression appts. The syringes are connected to the needle or catheter, to be introduced into the blood-vessel or organ it is intended to inject, by a flexible tube. The vessel or organ is thus opacified. The injection of viscous prods. can be made without exertion as the compressing mechanism is driven by a remote controlled electric motor at a variable speed. A supplementary element allows the syringes to be refilled by suction; this shortens the duration of the examination and avoids the usual handling, with the risks of contamination. Device allows the abdominal compression appts. fitted to remove-controlled radiodiagnosis tables, to be converted to automatic injectors for the contrast prod.

Title: Electrical power supply control device - operating element with contacts rotatable about printed circuit base
IPC: H01C1/12
Filed: 1974-10-11
Abstract: An operating element rotatable about an axis (X-X) perpendicular to the base (34) carries contacts (19a, 19b, 19c) which connect with certain components on the printed circuit (36, 60, 62), so that the circuit is selectively controlled, and the load supplied with corresponding ratings of electric energy. The connection between the operating element and the contacts is effected via a resistor section in the form of circular strips. The variable resistance thus created constitutes a relatively long track along which the associated contact can be moved. The accuracy of regulation is thereby improved. The simplicity of working enables a compact construction to be realised.
