Påverkan av utloppsrörets längd i en automatiskt självtömmande hävert och komponenternas påverkan på tömningshastigheten

Sammanfattning: To facilitates tasks in modern healthcare, innovative solutions can be used and the product Sippi is an example of this. Sippi is a self-emptying siphon device used for monitoring a patient ́s urine production. This report examines one of the two main components of Sippi, known as the disposable unit. The unit consist of a siphon which is self-emptying without needing any mechanical assistance. The purpose of the report is to understand how some vital components of Sippi affect the emptying rate and determine the optimal length of the outlet tube. Theoretical calculations and experiential methods are used for the investigation. From the data and with help of software from Observe Medical, results could be generated in various forms, leading to several conclusions. The examined components, which were the bell and the filter had a negative effect on the emptying rate, resulting in a decreased rate when in use. Regarding the pressure drop, it was concluded that longer pipes generated greater pressure drop across the pipe. Additional studies are required to establish the ideal length of the outlet tube.
