HAEMODIALYSIS DEVICE Russian patent published in 2024 - IPC A61M1/14 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Haemodialysis device comprises a manifold comprising an arterial and venous line, a patient input connector, a venous pressure sensor, a thrombus filter and a dialyzer. Arterial line includes the connected patient's input connector, a clamp, a mixer, to which the anticoagulant supply line is connected, and a peristaltic pump installed with the possibility of acting with rollers on the pump segment of the polyvinyl chloride tube. Output of the pump segment is connected to the input connector of the dialyzer. Output connector of the dialyzer is connected to the input of the venous line. Additionally introduced are first-fourth T-shaped injection connectors and spider. First T-shaped injection connector is installed in the arterial line and is connected to the mixer by its output. Mixer is connected by means of a spider to a pump segment, which is circular and through a second T-shaped injection connector is connected to the input of the dialyzer, which output is connected through the third T-shaped injection connector and the T-shaped valve to the input of the thrombus filter. Venous pressure sensor and a fourth T-shaped injection connector are connected to the input of the thrombus filter. Output of the thrombus filter is connected through a clamp to the output connector of the patient.

EFFECT: providing simultaneous introduction of anticoagulant into arterial line and additionally into arterial and venous lines of drugs.
