#2701: SampleScope

In the world of biomedicine, there are many translucent liquids stored in sample jars.

Today’s invention offers a way to perform some simple visual tests on these, without having to open the container.

The sample container has a lens moulded into the base and something like a visual testcard printed on the inside of the lid.

This allows a medic or nurse to view the testcard through the liquid.

The testcard could have colour patches for comparison with the colour of the liquid (eg for urine diagnosis). It could also carry a grid of lines which would be distorted or defocussed to a known degree by the presence of liquid with unusual density (or optical properties, eg cloudiness).
