Programmable System on Chip Clog Detection using Slope Detection for Ventriculoperitoneal Shunt Application

Abstract

Hydrocephalus is a life threatening neurological disorder that until now has no cure. It is characterized by a build-up of cerebrospinal fluid in the ventricles of the brain. Ventriculoperitoneal shunting is the most recommended treatment by doctors which helps release the CSF by implanting a shunt valve system from the brain to the abdomen, thus allowing the fluid to flow. However many complications arise from the treatment causing malfunctions to the system and unnecessary revision surgery, the biggest of which is shunt blockage. Shunt blockage can be done by tissue, cellular debris, and blood clot. This paper aims to discuss a clog detection method that uses slope detection to avoid false shunt triggering arising from body movements. This helps avoid over draining and allows the system to work as it should be.
