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 invention relates to a device and method for local administration of a medical fluid. The device having a hose which is flexibly deformable and has a hose wall. The hose wall has an outer wall ofa first material, which is arranged radially to the outside, and the an inner wall of a second material, which is arranged radially to the inside and which delimits an inner conduit of the hose. In adistal portion of the hose, the hose has multiple orifices in the hose wall. The multiple orifices connect the inner conduit with the surroundings of the hose. The distal portion of the hose is delimited by a distal end of the hose, the device further has a closing element, the hose is closed or closable in a liquid-tight manner at the distal end of the hose by means of a closure element. The closing element is manually insertable into the distal end of the hose. A proximal end of the hose is connectable with a container for the medical fluid such that the medical fluid is able to be forced out of the container through the proximal end of the hose into the inner conduit of the hose and forced through the multiple orifices to the surroundings of the hose.

Description

technical field [0001] The present invention relates to a device for the temporary local 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 invention is in particular a medical device for the temporary local administration of medicinal fluids or other medical fluids over a period of hours to days. Depending on the respective geometrical requirements and / or the anatomical conditions of the implantation site, the device according to the invention can be adapted to length without loss of function by simple mechanical shortening. Furthermore, a device for the continuous discharge of medical fluids is proposed, which can advantageously be combined with a device for topical application of medical fluids, so that the continuous local application of medical fluids or other medical fluid. [0003] Topical administration of active pharmaceutical i...
