Abstract [sv]

Vid idrott utomhus i minusgrader utsätts andningssystemet för stora påfrestningar, luften är kall och torr vilket skadar och irriterar luftvägarna. För att undvika det kan man använda fukt- och värmeväxlare (HME). Dagens produkter har dålig passform vilket leder till läckage av luft.

Syftet med projektet är att fler vinteratleter ska vilja använda HME och därmed förebygga förekomsten av andningssjukdomar. De tre delmålen för projektet är att tillverka minst en prototyp, den tillverkade prototypen ska ha bättre passform än dagens produkter och minst en lösning för slemhantering ska presenteras.

Med hjälp av litteraturstudier lades en kunskapsgrund inom området. Verktyg som branschanalys, intressentanalys och målspecifikation gjorde konceptgenereringen rikare. Största delen av projektet lades i prototyptillverkning.

Två prototyper kunde till slut presenteras, Winterflow och Winterflow Pro. Det är två additivt tillverkade masker med tillhörande filter som konstruerats i ett datormodelleringsprogram. Prototyperna validerades med hjälp av användartester. Prototyperna upplevs för en del testpersoner ha bättre passform än dagens produkter, men ingen statistisk signifikant skillnad gick att bevisa.

Målen och syftet uppfylldes delvis och en bredare grund för vidare forskning fastställdes.

Abstract [en]

When performing sports outdoors during sub-zero conditions the respiratory system is exposed to great stress, the air is cold and dry, which damages and irritates the airways. To avoid this, the athletes can use heat and moisture exchanging devices (HME). Today’s products have a poor fit, which leads to leakage of the air.

The aim of the project is to increase the usage of HME for winter athletes and thereby prevent the occurrence of respiratory diseases. The three objectives for the project are to manufacture at least one prototype, the prototype shall have a better fit than today’s products and at least one solution for handling saliva matter shall be presented.

By carrying out literature studies, a foundation of knowledge was laid in the area. With the help of different analysis and tools, the concept generation were richer, resulting in more solutions. The main part of the project was put into prototyping.

Two prototypes could be presented at the end, Winterflow and Winterflow Pro. Two additive manufactured masks with associated filters constructed in a computer modelling program. The prototypes were validated by user tests. The prototypes were perceived by some testers to have a better fit than today’s products, but no statistically significance could be proven.

The aim and objectives were partly met, and a broader foundation of knowledge for further research was established.
