Abstract

A device for measuring parameters of medical fluids having a measurement chamber through which the fluid to be measured passes. The chamber is sealed on one side by a flexible membrane, and it also has a measurement plate that has a peripheral seal on its outer edge and is in contact with the flexible membrane. At least one sensor for measuring a parameter of the medical fluid is mounted on the measurement plate, and the measurement plate has a continuous inlet leading to the flexible membrane so that a vacuum can be established between the measurement plate and the flexible membrane.
