Test probe for iso-volumetric pressure measurement appts. - has chamber with diaphragm connected to another diaphragm and includes micro-cannula probe

摘要

The probe has a microcannula (6) inserted into an allocated pressure chamber (7), in which a pipe (11) with a valve (10) ends, for its and the cannula filling. It is closed on one side by an elastic diaphragm (8). The pressure chamber (7) has a dismountable fastening (12) for connection of the diaphragm (8) with a further diaphragm (9) of an isovolumetrically controlled chamber (3) of a known device for isovolumetric pressure measurement.
