Device and method for catching a biological specimen

A method of illuminating a main chamber of a device configured to catch a biological specimen removed from an individual, the main chamber having an interior wall and an exterior wall, wherein the device comprises an inlet in fluid communication with the main chamber, a filter defining a filter path and configured to be removably inserted into the main chamber, and an outlet in fluid communication with the main chamber, wherein the inlet, main chamber, and outlet form a fluid flow channel the method comprising:

• obtaining a volume of a light emitting material in a container,
• activating the light emitting material to emit light;
• and
• placing the container in a receiving structure before catching the biological specimen removed from an individual, wherein the receiving structure is attached to at least a portion of the interior wall or the exterior wall of the main chamber and positioned such that the receiving structure does not obstruct either the inlet channel or the outlet channel, wherein the receiving structure comprises a hollow lumen having a first wall positioned flush against the interior wall of the main chamber and a second opposing wall defining an elongated opening sized to removably receive the container, is configured so as to avoid obstruction of the inlet and outlet and the filter path, is configured to illuminate the main chamber when the container is inserted, and is located adjacent the filter and relative to the fluid flow channel such that illumination occurs without the light emitting material contacting the specimen.
