Also, such devices are generally expensive to manufacture and need skilled nursing staff to apply the devices onto a user’s body.
  • Another category of conventionally known fecal collection devices comprises wearable sanitary products, such as diapers. Such wearable products not always be easily put-on on a person. Also, removal of the product after the product is soiled is difficult. Furthermore, these products do not always adapt to the anatomy of users well. Consequently, the likelihood of fecal matter excreted by a user to spread around the anal region is high. Spreading of the fecal matter not only make cleaning of the fecal matter difficult, it also makes the person susceptible to various infections that may be caused by the fecal matter.

Further, if the pressure drop is slower than the predetermined later, such that the pressure drop has a little variation (a pre-known value, such as variation of 1-2 bar) from the predetermined rate, then it can be inferred as presence of foreign object in the transit component 104.

Based on a knowledge about the amount of fluid, the control device 412 can accordingly monitor and manage the amount of the fluid being injected into the transit component (104).
