Abstract
The present invention relates to a pressure measurement unit to determine positive and negative fluid pressure within a disposable for medical devices. As part of the disposable, the invention consists of a rigid measurement chamber, which is covered by an elastic form part. This measurement chamber can be connected to a medical device, which is equipped with a pressure transducer. Specific shapes of the elastic form part and specific instrument interfaces ensure the connection between this elastic form part, the measurement chamber and the pressure transducer to exclude the influence of atmospheric pressure during measurements. The coupling and the sealing ability against atmospheric pressure is controllable. Such pressure measurement units can be used to measure fluid pressure in disposable to control for example fluid pumps.
