Pressure Monitoring System

A pressure-measuring system, with at least a first measuring lumen which can be filled with a fluid, comprising:

• a tube system that defines the first measuring lumen and is connectable to (a) a fluid reservoir serving as a supply of fluid and to (b) at least one catheter lumen of at least one catheter, and
• a mechanism for conveying the fluid through the tube system and into the at least one catheter,
• at least first and second pressure measuring devices, each pressure measuring device including a pressure transducer membrane and a measuring chamber which can be filled with fluid;
• at least a first flow regulation device and at least one non-perfusion flow regulation device;
• wherein the tube system further includes at least one coupling element which mechanically connects each measuring chamber via its respective membrane with a measuring area of a pressure transducer and each measuring chamber has at least two connection points for a fluid flow;
• the first flow regulation device is positioned between the first pressure measuring device and the supply of the fluid, with a perfusion tube section made of a flexible material and having a perfusion tube section lumen through which fluid can flow and has a first tube clamp into which the perfusion tube section is inserted;
• the first flow regulation device can be set to regulation positions open, closed and perfused, wherein in the closed position the perfusion tube section lumen is completely squeezed closed and in the perfused position, through a spacer in the inside of the perfusion tube section, the perfusion tube section lumen is partly open even when squeezed by the first tube clamp;
• wherein the first tube clamp has a basic housing with an accommodating area for the perfusion tube section and a first clamping element that can be moved between three regulation positions, and wherein the first clamping element in interaction with sections of the accommodating area as pressing points in at least one regulation position acts on the tube section and its lumen by squeezing;
• and
• wherein the at least one non-perfusion flow regulation device has a non-perfusion tube clamp having a basic housing with an accommodating area for a second, non-perfusion tube section having a non-perfusion tube section lumen and a clamping element that can be moved between open and closed regulation positions, and wherein the clamping element in interaction with sections of the accommodating area as pressing points in at least one closed regulation position acts on the non-perfusion tube section lumen by squeezing.
