The invention relates to a protective sleeve (1) in the form of a hose (4), having an outer lumen (40) and an inner lumen (42) disposed eccentrically therein. The outer lumen (40) is delimited to the exterior by an outer wall (41), and the inner lumen (42) is delimited by an inner wall (43). The two walls (41, 43) transition into a common wall segment (44) which has a thinnest region (48) acting as a membrane. Pressure sensor windows (11) can be provided in said region. Said pressure sensor windows are closed by a highly flexible, thin film. This can be done by means of a shrink film tube. A reusable pressure sensor catheter can be inserted into the inner lumen (42), while a rinsing solution can be introduced into the patient through the outer lumen. Reusable pressure sensor catheters can be used a plurality of times without requiring a sterilization process. The protective sleeve (1) is replaced after each use.
