Avon A15 Blood Administration Set.

Avon A15 Blood Administration Set. This particular type was the second generation issued for use with the plastic polyfuser and bag stored fluids (volume expanders). The original issue 'giving sets' had an air inlet line, which hung-upwards above the fluid to ensure an uninterrupted flow. This was necessary as the fluid was carried in glass (yes glass!) bottles. 'Dextran 70' was the actual replacement fluid first issued.
