infusion of one's own blood/substance
Etymology
'autoinfusion' is formed from the combining form 'auto-' (from Greek 'autos', meaning 'self') + 'infusion' (from Latin 'infusio', from 'infundere' 'to pour into').
'infusion' comes from Latin 'infusio' (from 'infundere'), passed into Old French and Middle English as 'infusion'; the prefix 'auto-' comes from Greek 'autos'. The compound 'autoinfusion' is a modern medical coinage combining these elements.
Originally, 'infusion' meant 'a pouring in'; over time it took on medical senses (administration of fluids/medicines). 'Autoinfusion' developed to mean specifically the reinfusion of one's own substances (especially blood).
