FLUID ANALYSIS MODULE, AS WELL AS FLUID ANALYZER Russian patent published in 2022 - IPC G01N33/48 A61B5/145 B01L3/00 

FIELD: medical equipment.

SUBSTANCE: invention can be used for the analysis of biological fluids, preferably blood. A fluid analyzer contains control and assessment unit (3), to which fluid analysis module (1) is rigidly connected with the possibility of a detachment, containing case (4) and fluid input port (10), with at least one fluid sensor (12) integrated inside case (4) with sensor surface (11) made with the possibility of a fluid connection to fluid input port (10). Inside case (4) of the module, chamber (7) is integrated, made with the possibility of a fluid connection to surface (11) of sensor (12), inside which first liquid tank (8) is installed, made with the possibility of a fluid connection to surface (11) of sensor (12) of fluid. At least on sections of one surface (20) of the module case, elastic hermetic membrane-shaped separation wall (22) is installed, under which at least one fluid functional element in the form of flow valve (13) and at least one fluid functional element in the form of a feed pump (14) are installed. In this case, fluid functional elements (13, 14) can be actuated by means of exceptionally local mechanical deformation of the separation wall, at least in one of following ways: a) by exceptional flow of fluid from the fluid input port along sensor surface (11) into chamber (7), as well as b) by exceptional supply of liquid stored in at least one liquid tank (8) from liquid tank (8) along sensor surface (11) to chamber (7). Mechanical actuators provided on the side of control and assessment unit (3) are brought into contact with fluid functional elements (13, 14) through separation wall (22).

EFFECT: safe and reliable fluid analysis is provided, as well as calibration and cleaning of the sensor with maximum compactness of the analyzer.
