CONTAINER FOR MEDICAL FLUIDS AND METHOD OF FILLING SUCH CONTAINER Russian patent published in 2022 - IPC A61J1/20 A61M5/145 B65D83/42 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to container (1) for injecting medical fluids and a method for filling container (1). Container includes inner container (3) with distal end (5) and proximal end (7). First porous separating element (9) is located at proximal end (7). Porous separating element (9) limits receiving volume (15) for receiving medical fluid, container includes external container (17), in which inner container (3) is located with proximal end (7) and receiving volume (15). Outer container (17) tightly surrounds inner container (3), so that in circumferential volume (23) located between outer surface (19) of inner container (3) and inner surface (21) of outer container (17), the gas under excessive pressure can be located. Section (25) of the outlet channel is connected to distal end (5) of inner container (3). Section (25) of the outlet channel is located outside outer container (17). Discharge channel section (25) is configured to arrange valve device (29) thereon, which is adapted to unblock the fluid connection between the distal outlet opening (31) of the outlet channel section (25) and receiving volume (15), and in the closed position, block the fluid connection between distal outlet (31) and receiving volume (15). Method of filling container (1) for injection of medical fluids includes filling circumferential volume (23) of container (1) with a gas at a first predetermined pressure, filling receiving volume (15) of inner container (3) with a medical fluid at a second preset pressure, which is higher than the first preset pressure, and closing valve device (29).

EFFECT: improved ergonomics and ease of use, high-precision provision and dispensing of small amounts, ensuring multiple use, providing storage of oxygen-sensitive medical fluids, eliminating patient contact with lubricant, increasing tightness under vacuum and/or pressure load, providing certain flow rates of medical fluid when dispensing from the container, eliminating the need to remove an air bubble from the container before injection.
