Medical detection dogs or bio-detection dogs are trained to detect the smallest odours with concentrations, around one part per trillion.
Working with registered charities such as https://www.medicaldetectiondogs.org.uk we have helped design analysis stands for medical conditions such as breast cancer, Prostate Cancer, Bowel Cancer, Malaria and Parkinson’s and most recently coronavirus.
The stand we designed has completely welded seams to eliminate any cross-contamination from sterilizing and has interchangeable sample retaining clips. This allows the clip to be changed to accept other samples or just simply replaced when worn out.
The arm also has a detachable cone to allow greater focus amplification of the odour.
The other clever part about our design was to incorporate a restriction to stop the tongue licking urine, which is a natural thing for dogs to do. The first stands we produced with cross wires, but some doges were still able to bypass the restriction. We then came up with the idea of using an inverted pepper pot.
This shape was ergonomically good because it fitted the shape of the dog’s nose while allowing the dog to get as close as possible to the substance and at the same time prevented the dog from licking the sample.
