1. An apparatus, comprising:
a support structure including a coupling element detachably coupleable to a delivery element and defining a cavity configured to receive an ear of a subject;
a first reservoir coupleable to the support structure and configured to contain a first volume of fluid;
a first channel configured to provide fluid communication between the first reservoir and the coupling element such that the first volume of fluid can be delivered from the first reservoir to the coupling element;
a vacuum assembly disposed in the support structure and fluidically coupled to a second reservoir, the vacuum assembly configured to draw fluid from the ear of the subject to the second reservoir via a second channel by generating a negative pressure in the second reservoir; and
a second channel configured to provide fluid communication between the second reservoir and the coupling element such that the second volume of fluid can be received in the second reservoir from the coupling element.
