Cancer Detection Dogs
Tuesday, October 28th, 2008
Demand was approached in the summer of 2008 by Claire Guest, who is conducting research in the area of dogs who can detect cancer cells in samples of urine. The dogs smell small samples which are contained in plastic vials. The object of this research is to confirm or otherwise, the dog’s ability to do this successfully. If confirmed, a machine will be developed that will mimic the dog’s cancer-detecting ability which will lead to a low-cost but effective cancer-screening programme for all. Early diagnosis can dramatically increase the likelihood of surviving certain types of cancer.
The designers from Demand were invited by Claire to see how her research was conducted at the specially adapted premises near Aylesbury. The procedure was observed and discussed with the research assistants to see how it could be speeded up. It was agreed that some form of apparatus would assist them in their work and one of the designers at Demand was allocated the project.
A concept was sketched out, then more detailed drawings were produced in a 3D parametric modelling application before a prototype machine was constructed in the workshop. This was taken for testing in August 2008.
The apparatus consists of a ‘carousel’ containing eight ‘stations’, each of which holds a sample containing urine. This urine may or may not contain cancerous cells. The dogs go to each ‘station’ in turn and indicate to the research assistant which sample, if any, contain these cells.
Claire and her assistants are delighted with what Demand have designed and made for them. They say that it speeds up their research programme by hours each day.
