Device Of An Infusion System

Device for an infusion system to deliver an infusion fluid from a bag through a tubing to a user location via a veinflon/cannula, where the infusion bag is arranged to be placed in a box that can be closed, whereby the pressure is maintained by a tension spring being fitted inside the box, and which creates a pressure against the bag so that the fluid flows through the tubing to the user location, characterised in that the spring is made to put pressure on the infusion bag via a rigid, pressure distribution plate placed inside the box, that covers the surface of the bag, where the plate as broad as the bag, so that as the bag is squeezed together and is being emptied of fluid, the intermediate plate is pushed downwards and creates a permanent pressure on the bag.

Device for a reduction valve for regulation of the pressure in a fluid that flows through a tubing, where the valve is arranged to be connected to the tubing, characterised in that the valve comprises a first end wall and a second end wall mutually spaced apart in the form of a flexible membrane, where a smaller tubing of a given length is connected between and to the membrane and the end wall, respectively, said tubing being arranged to maintain a fluid connection between the tubing area upstream and downstream, respectively, of the valve, via respective openings or channels through the end wall and the membrane, respectively.

Infusion system for the delivery of an infusion fluid from one of a container and a bag through a tubing to a user location via a veinflon/cannula, means to maintain pressure in the bag so that the fluid flows through the tubing to the user location, and also means to regulate the pressure in the infusion bag, characterised in that the system is arranged to be used as an individual solution where the box with the bag of infusion fluid is carried freely at the user location.
