The invention relates to a device for injecting liquid, comprising a piece of tubing on which there is situated at least a first liquid occlusion system. According to the invention, a regulation system ( ) is situated upstream from the first occlusion system, the two systems defining an intermediate segment in which the pressure, in the absence of injection, is greater than the pressure that exists downstream from the first occlusion system so as to direct any leak of liquid from the first occlusion system downstream. The invention is applicable to a pump used for injecting contrast liquid for medical imaging.

Medical device for injecting liquid

The present invention relates to the treatment of kidney insufficiency and more particularly to a peritoneal dialysis device. The device is adapted to function in tidal peritoneal dialysis (TPD) mode, the device being characterized by the fact that it is provided with a variation system for varying the parameters of dialysate exchange over time. The system is designed in such a manner as to vary the duration between two cycles for exchanging fractions of dialysate.

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 ( ) provided with a circularly arcuate slot ( ) which is extended by a circular orifice ( ). The closure piece ( ) can be rotated about a point O on a circle of radius (R) equal to the radius of the slot ( ).

Pinch obturating device for a flexible tube

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.
