| 20090099545 | Self-contained portable apparatus for administration of a drug solution - A self-contained portable apparatus for administration of a drug solution is disclosed, comprising: a housing having an enclosure for receiving a flexible pouch containing a drug solution, the output of which is connectable to a conduit for delivering said drug solution to a recipient. A pressurization system is arranged for providing a constant and controllable gas pressure to the housing, wherein a controllable pressure is obtained for a controllable delivery of the drug solution. The pressurization system comprises: a pressure source for delivering positive pressure gas; a pressure accumulation tank connected to said source and to said second chamber, arranged to provide a positive pressure reservoir; a one-way valve arranged between said pressure source and said pressure accumulation tank, enabling gas to flow solely in the direction from the pressure source to the pressure accumulation tank; and a mechanical pressure regulator arranged between said pressure accumulation tank and said housing. Hereby, an extremely stable and well controllable output pressure and output flow is obtainable. | 04-16-2009 |
| 20080200907 | Folded Catheter Assembly With Adhesive Grip - A catheter assembly is disclosed comprising a catheter and a receptacle enclosing said catheter. The receptacle has a first part and a second part, which parts are foldable over each other. Further, at least one sticky adhesive area is arranged on the surface of one of the parts of the receptacle in such a way that the sticky adhesive area is covered by the other part when the receptacle is in a folded disposition, and exposed to the environment when the receptacle is in an unfolded disposition. | 08-21-2008 |
