Application of Quality Function Deployment (QFD) And Theory of Inventive Problem Solving (TRIZ) To Designing an Automated Blood Separator

Abstract

This research study is aimed at meeting the needs of users of the blood component separation system which is necessary for patients who need blood. The purpose of this study is to design a blood component separation system of the size and operating procedure that meets the needs of users. The research began with an investigation of information of personnel (Voice of Customer: VOC) of the Central Blood Bank of Srinagarind Hospital in Khon Kaen Province. A questionnaire was then administered to respondents who were asked to rate the importance of each of the customer requirements. The customer requirements and importance rating were analyzed, using QFD technique consisting of two matrices, namely product planning and part development. The product planning matrix transformed customer requirements into the technical requirements whereas the part development matrix further transformed technical requirements into part characteristics. The Theory of Inventive Problem Solving (TRIZ) was also applied. Then, part characteristics were used to design and produce the device. As a result of this research study, part characteristics are obtained and can be used to design a blood component separation system of the size and operating procedure that meets the needs of users and international standards.
