FIELD: medicine.

SUBSTANCE: group of inventions refers to advanced enteral nutrition appliances. What is presented is an enteral nutrition catheter assembly comprising: a catheter having a proximal end, a distal end and catheter walls forming a catheter cavity; a carrier arranged at the proximal end of the catheter; the carrier forms a catheter cavity aperture; the carrier has the first end and the second end; an inflatable cylinder having a preset filling volume; the cylinder is arranged at the distal end of the catheter; an inflation valve on the carrier; the inflation valve is fluid connected to the cylinder by an inflation cavity formed by the catheter walls; a pre-displacement indicator unit on the carrier fluid connected to the cylinder; the pre-displacement indicator unit is configured so as to set a discrete visual signal showing that a fluid pressure in the cylinder differs from the preset pressure, or the cylinder volume differs from the preset filling volume. There are also described the cylinder enteral nutrition catheter device and the indicator unit for recording discrete visual signals when used for medical purposes.

EFFECT: achieved higher reliability and efficiency when providing enteral nutrition.
