Patent ID: 7704236

Claim:
A distribution device for a system ( 1 ) for delivery of medical fluids to a patient, comprising; a syringe body ( 30 ), a feed tube ( 56 ) for an active medical fluid, opening into the syringe body ( 30 ) and designed to be connected to a reservoir ( 6 ) for the active medical fluid, a distributor ( 32 ) comprising a distributor body ( 32 B), within which there is bounded a chamber ( 62 ) for fluid circulation, and within the chamber ( 62 ) there are both a slide ( 112 ), which can move in relation to the distributor body ( 32 B) and which forms, with walls of the chamber, a compartment ( 126 ), and a resilient member ( 120 ) placed between the slide ( 112 ) and a fixed part ( 122 ) of the distributor body, an injection tube ( 60 ), for the injection of the active medical fluid, connected to a distal extremity ( 46 ) of the syringe body ( 30 ) and opening into the chamber ( 62 ), a pressurised tube ( 64 ), designed to be connected to the patient through a pressurised line ( 12 ) of the system ( 1 ), directly connected and opening into the chamber ( 62 ), a pressure measurement tube ( 66 ), designed to be connected to a pressure measurement line ( 16 ) of the system ( 1 ), and opening into the chamber ( 62 ), and a flush tube ( 68 ) which is separate from other tubes ( 56 , 60 , 64 , 66 ) of the device, which is formed in the distributor body ( 32 B) and which comprises a first section ( 68 A), which is designed to be connected to a reservoir ( 24 ) for a flush medical fluid, and a second section ( 68 B) opening directly into the chamber ( 62 ), said flush tube ( 68 ) being fitted with a valve ( 70 , 80 ) equipped with a plug ( 70 ) which is located between the first and second sections ( 68 A, 68 B) of the flush tube and which can be moved manually between a position in which it at least partly closes the flush tube and a position in which the flush tube ( 68 ) is in free communication with the chamber ( 62 ), wherein the distributor provides an automatic connection via the chamber between the pressurised tube ( 64 ) and either the injection tube ( 60 ) or the pressure measurement tube ( 66 ) through the action of the pressure of the active medical fluid and the resilient member ( 120 ), the active medical fluid circulating via the compartment ( 126 ) between the pressurised tube ( 64 ) and the pressure measurement tube ( 66 ) when they are in connection, and wherein the distributor ( 32 ) connects the flush tube ( 68 ) with the pressurised tube ( 64 ) and with the pressure measurement tube ( 66 ) via the chamber ( 62 ), the flush medical fluid circulating via the compartment ( 126 ) between the flush tube ( 68 ) and the pressure measurement tube ( 66 ) when they are in connection.
