An aspirator for manually collecting liquid samples, particularly for medical purposes, comprising a handle connected to a vacuum source and having a sample collection vial fitting into a cavity in the handle with a finger control vent in the cavity and having a tubing to function as the probe for the sample to be collected, the tubing leading into the sample collection vial.
A viewer for optically inspecting the interior ear cavity having a tubular body with a passage having an open end adapted to be inserted into the ear cavity and a lens in optical alignment with the passage. A light mounted on the viewer operates to illuminate the passage and interior cavity adjacent the open inner end thereof. The viewer is used with a collector to manually collect liquid samples from the ear cavity. The collector has an elongated tube associated with a plunger that is spring biased to an out position. A releasable latch holds the plunger in an in position. When the latch is disengaged from the plunger the biasing spring moves the plunger to its out position thereby drawing fluid into the tube.
