Compounding device, system, kit, software, and method

A junction structure for use in a pharmaceutical compounding device, the compounding device having a housing that supports a pump system and a valving mechanism, the junction structure comprising:

• a junction body;
• a first inlet port located at a first portion of the junction body;
• a second inlet port located at a second portion of the junction body;
• an outlet port located at a third portion of the junction body;
• a mixing chamber located between the outlet port and both the first inlet port and second inlet port, the mixing chamber configured to mix fluid received from both the first inlet port and second inlet port and to deliver the fluid to the outlet port;
• an attachment structure located on the junction body and configured to attach the junction structure to the housing of the compounding device;
• and
• a manifold configured for attachment to the valving mechanism of the compounding device, a macro line extending from the manifold to the pump system and to the junction body, a micro line extending from the manifold to the pump system and to the junction body, wherein the junction body, first inlet port, second inlet port and mixing chamber are located downstream of the pump system and configured such that fluid from the micro line and macro line are caused to mix at the mixing chamber after passing the pump system,
• wherein the macro line and micro line are in fluid isolation from each other upstream of the junction body, and
• wherein the manifold includes a micro channel and a macro channel, and a cross-sectional area taken normal to a longitudinal axis of the micro channel is less than a cross-sectional area taken normal to a longitudinal axis of the macro channel.
