Container for fluids and apparatus for temperature control, e.g. warming, of medical fluids

A container for enabling fluid flow, wherein the container comprises a flexible bag with at least a first and a second film sealed to one another, the container further comprising:

• an inlet port;
• an outlet port;
• and
• a fluid conduit to put the inlet port in fluid communication with the outlet port, the fluid conduit comprising
• one or more deflection sections,
• a connection section located upstream from at least one of the one or more deflection sections, and
• a successive connection section located downstream from the at least one or more deflection sections, wherein the fluid conduit has a maximum width in a direction of the fluid flow through the fluid conduit,
• wherein at least one of the one or more deflection sections further comprises an entry section and an exit section, each respective exit section being arranged downstream, in the direction of the fluid flow, from each respective entry section,
• wherein, for each of the one or more deflection sections
• the entry section has a first end and a second end, the first end of the entry section being upstream, in the direction of the fluid flow, of the second end of the entry section,
• the entry section includes an inner edge having a nonlinear shape with a concave curve trend in a first portion and a convex curve trend in a second portion and an outer edge having a linear shape, wherein the outer edge contacts and continues straight from an outer edge of the connection section,
• the exit section has a first end and a second end, the first end of the exit section being upstream, in the direction of the fluid flow, of the second end of the exit section, wherein the exit section includes an inner edge having a linear shape corresponding to a line segment positioned at an angle with respect to an outer edge of the exit section, wherein the outer edge of the exit section contacts and continues straight from an outer edge of the successive connection section in the direction of the fluid flow, and
• an intermediate section interposed between the entry section and the exit section, the intermediate section having a constant width, the intermediate section being provided with a deflection of about 180°,
• wherein a width of the fluid conduit decreases along the direction of the fluid flow through the entry section over a first distance from the maximum width to a narrower width and the width of the fluid conduit increases constantly along the direction of the fluid flow through the exit section over a second distance from the narrower width to the maximum width,
• wherein the width of the fluid conduit at the first end of the entry section is equal to the width of the fluid conduit at the second end of the exit section and the constant width of the intermediate section is equal to the narrower width, the first distance being smaller than the second distance, wherein

A container for enabling fluid flow, wherein the container comprises a flexible bag with at least a first and a second film sealed to one another, the container further comprising:

• an inlet port;
• an external inlet tubing having a section diameter and being connected to the inlet port;
• an outlet port;
• and
• a fluid conduit configured for putting the inlet port in fluid communication with the outlet port, the fluid conduit comprising
• one or more deflection sections,
• a connection section located upstream from at least one of the one or more deflection sections, and
• a successive connection section located downstream from the at least one or more deflection sections,
• wherein the fluid conduit has a maximum width in a direction of the fluid flow through the fluid conduit and a conduit height, the section diameter of the inlet tubing being larger than the conduit height,
• wherein at least one of the one or more deflection sections further comprises an entry section and an exit section, each respective exit section being arranged downstream, in the direction of the fluid flow, from each respective entry section,
• wherein the entry section includes an inner edge having a nonlinear shape and an outer edge having a linear shape, wherein the outer edge contacts and continues straight from an outer edge of the connection section,
• wherein an inlet section fluidly connects the inlet tubing with the fluid conduit,
• wherein the inlet section comprises a first plane and a second plane, opposite to the first plane, developing from the inlet tubing towards the fluid conduit and converging towards the fluid conduit, and
• wherein the exit section includes an inner edge having a linear shape corresponding to a line segment positioned at an angle with respect to an outer edge of the exit section, the outer edge of the exit section contacting and continuing straight from an outer edge of the successive connection section in the direction of the fluid flow.
