   Sammanfattning : Sepsis characterized by severe bloodstream bacterial infection that results in high mortality rates and medical expenses has become a global healthcare challenge. The current clinical sepsis diagnosis is based on blood culture and requires a long waiting time, delaying effective treatments. LÄS MER

3. 27. Design of the medical device Sangair SangAsept : A usability, conceptualization and design centered analysis of a blood treatment device

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Björn Carlshamre; Kristoffer Regard; [2023]
   Nyckelord :;

   Sammanfattning : This thesis report presents a collaborative project carried out by Industrial Design Engineering students, Björn Carlshamre and Kristoffer Regard, together with KTH, Svensk Konstruktionstjänst AB ("Svekon") and Sangair AB. The project mainly explores research and implementation of human centered design of an extracorporeal ozone therapy medical device for sepsis treatment, Sangair's recent successful study on swine and human blood demonstrated the effectiveness of their ozone treatment method for eliminating bacteria and potentially revolutionizing sepsis treatment.
