Problems solved by technology

Cannot deliver medical fluids quickly and short-term
Also, with prolonged catheter use (more than a day), the tissue surrounding the catheter can grow into the orifice, creating considerable problems when withdrawing / removing the catheter
Therefore, removing the catheter may damage surrounding tissue, reducing treatment success

Abstract

The present invention relates to an apparatus and method for topical administration of medical fluids. The device has a hose that is flexibly deformable and has a hose wall. The hose wall has an outer wall of a first material and an inner wall of a second material, the outer wall being arranged radially outside, and the inner wall being arranged radially inside and delimiting the inner conduit of the hose. The hose has a plurality of orifices in the hose wall in the distal portion of the hose. A plurality of orifices connect the inner conduit of the hose with the surrounding environment of the hose. The distal portion of the hose is bounded by the distal end of the hose. The device has a closing element by which the hose is closed or can be closed in a liquid-tight manner at the distal end of the hose. The closure element can be manually inserted into the distal end. The proximal end of the hose is connected or connectable in a liquid-permeable manner with a container for medical fluid, so that the medical fluid can be pressed from the container through the proximal end of the hose into the inner conduit of the hose and through Multiple orifices press out into the surroundings of the hose.

Description

technical field [0001] The present invention relates to a device for the temporary topical administration of medical fluids, in particular pharmaceutical fluids. The invention also relates to a method for operating such a device. Background technique [0002] The subject of the present invention is in particular a medical device for the temporary topical administration of pharmaceutical fluids or other medical fluids over a period of hours to days. Depending on the corresponding geometric requirements and / or the anatomical conditions of the implantation site, the device according to the invention can be adapted in length without loss of function by simple mechanical shortening. Furthermore, a device for continuous discharge of medical fluids is proposed, which can be advantageously combined with a device for topical application of medical fluids, so that the topical application of medical fluids or other medical fluids. [0003] Topical administration of active pharmaceut...
