Abstract

The present disclosure relates to a cardiological sensing system for lung fluid detection. The system includes a base to which a movable stand is attached. The stand includes two vertical profiles with a rail connected to the horizontal profile with a rail via angle brackets, and a set of helical antennas oriented parallel to the plane of the base. The set of helical antennas are supported by horizontal crossbars and fixed using the angle brackets with screws to vertical profiles with the rail. Each of the helical antennas includes rectangular shielding made of copper sheet without walls on the side of patient thorax, and an inner cylinder-shaped carcass core with a copper wire wound thereon. A geometric center of the carcass core coincides with a geometric center of a ground and a shield. The helical antennas also include microwave coaxial cables connecting both helical antennas through an N-type coaxial connector with a vector network analyzer through a cable leading to a data analysis computer.

Claims (10)

1 . A cardiological sensing system for lung fluid detection, comprising:

a base to which a movable stand is attached, the movable stand including two vertical profiles with a rail connected to a horizontal profile via angle brackets; and

a set of helical antennas oriented parallel to a plane of the base, the set of helical antennas supported by horizontal crossbars and fixed using the angle brackets with screws to vertical profiles with the rail, and each of the helical antennas comprising:

rectangular shielding made of copper sheet without walls on a side of a patient thorax,

an inner cylinder-shaped carcass core with a copper wire wound thereon, wherein a geometric center of the inner cylinder-shaped carcass core coincides with a geometric center of a ground and a shield, and

microwave coaxial cables connecting the helical antennas through an N-type coaxial connector with a vector network analyzer through a cable leading to a data analysis computer.

2 . The system according to claim 1 , wherein the inner cylinder-shaped carcass core is made of High Impact Polystyrene (HIPS) material.

3 . The system according to claim 1 , wherein the shield and the ground are made of copper sheet.

4 . The system according to claim 1 , wherein the vertical profiles with the rail and the horizontal profile with the rail and the horizontal crossbars are made of aluminum.

5 . The system according to claim 1 , wherein the base is made of wood.
