Abstract: To perform a method for the reconstruction of a patient's body map, a detector has, in addition to the conventional sensors, an antenna placed in the direction of emission of the X-rays. At each position of the parts moving about the patient, electrodes of the antenna and the sensors simultaneously measure a distance between the patient's body and the detector. Means are used to carry out this reconstruction on the basis of the measured distances. The apparatus has means to achieve the following on the basis of this reconstruction: automatic control of the speeds of the moving parts of the apparatus, regulation of the X-ray dose and computation of the time of exposure to the X-rays.

Abstract: The invention relates to a closure device for closing a hose by pinching, and in particular for closing a flexible tube or hose used in the medical field. Essentially, the device comprises a closure piece (62) provided with a circularly arcuate slot (70) which is extended by a circular orifice (76). The closure piece (62) can be rotated about a point O on a circle of radius (R) equal to the radius of the slot (70).

Abstract: An assembly comprising a flanged flask and a syringe device fixable thereto is provided. The syringe device includes a guide member for cooperating with the body of the flask. The guide member includes a first end with an internal guide surface at its terminal portion and a fastening mechanism set back from the internal guide surface. The internal guide surface cooperates with the cylindrical body of the flask and the fastening mechanism attached to the flange of the flask. A second end of the guide member provides translational guidance to a syringe.

Abstract: A device for sensing gas bubbles in a liquid flowing through a duct, particularly the outlet duct of a peristaltic pump, including two piezoelectric components shaped and excited so that they vibrate axially. One of the components is a transmitter and the other is a receiver. One of the piezoelectric components is secured to a movable support, and its displacement is detected in order to detect excess pressure in the liquid flowing through the duct.

Abstract: The invention relates to injection apparatus that is capable of operating continuously. According to the invention, the apparatus comprises two independent injection bottles (12) of at least one liquid that is to be injected into a patient via a tube, each of the bottles including means (51) for detecting that injection of the liquid contained in the bottle has terminated, which means control means (53) for interrupting the flow of liquid. The apparatus comprises upstream injection apparatus (10) having two feeder tubes (50) connected to respective bottles (12), and downstream injection apparatus (70) with pump means (72, 84) for pumping the liquid and connected firstly to the patient via a downstream tube (78) and secondly to coupling means (54). An application is performing perfusion prior to radiological examination using an X-ray or an NMR scanner.
