FIELD: medicine.
SUBSTANCE: invention refers to medical pumps for medicinal agent infusion. Infusion pump contains electric control block, infusion set and needle fit. Novelty is that infusion pump contains disposable membrane pump consisting of case and membrane moving forwards and backwards by means of moving piston fixed in grooves on flange in membrane centre. Membrane case is furnished with inlet and outlet, and outlet of membrane case is connected to input elastic tube in the end of which input return valve is mounted by liquid source. Output of membrane case is connected to output elastic tube at the end of which output return valve is mounted by needle fit. Invention provides possibility of single application, prevents unpredictable fluid leakage due to prevention of elastic effect in infusion set, for example after hitch of pump or mechanical effect on elastic tubes or other related elements of infusion set.
EFFECT: prevention of unpredictable fluid leakage in infusion pump.
