PRESSURE CONTROL SYSTEM Russian patent published in 2021 - IPC A61M1/00 A61M3/02 A61M5/152 

FIELD: medical equipment.

SUBSTANCE: pressure regulation system (1) for fluid dispensing with preset fluid pressure from liquid orifice (10) includes elastic bag (3) with liquid (8) and gas phase (9). Hole (10) for liquid is made in working position of elastic bag (3) in lower area of elastic bag (3). Pressing elements (2) adjoin opposite walls of elastic bag (3). Drive unit (4) is designed to actuate at least one pressure element. Pressure elements are movable to each other by actuating said at least one pressure element. Control unit (5) is connected with drive unit (4). Elastic bag (3) has a gas hole that reaches gas phase (9). Pressure control system (1) has air injection and removal unit (6) which is connected to control unit (5) and adjoins opening for gas of resilient bag (3). Air delivery and removal unit (6) is made so, that by means of gas supply into elastic bag (3) and/or gas removal from elastic bag (3) to regulate pressure of liquid issued through hole (10) for liquid.

EFFECT: technical result consists in improvement of fluid pressure control, with which fluid is discharged from elastic bag.
