Plasma infusion unit
From Memory Alpha, the free Star Trek reference
A Plasma infusion unit was a medical device used to infuse bloodplasma into a patient.
In 2369, Doctor Crusher tried to use a plasma infusion unit to help Edward Hagler, whose blood had been turned into a liquid polymer by the solanogen-based lifeforms, but despite her efforts Hagler died. (TNG: "Schisms")
