Aplikace pružných struktur zhotovených metodou 3D tisku na podložku pro imobilní pacienty

Abstract

The dissertation thesis deals with the methodology of designing a new antidecubitus seating system for immobile patients using additive technology. Immobile patients use these systems to reduce the risk of developing a health problem - pressure ulcers. Currently, available systems may not adequately reflect the needs of the user. For this reason, a methodology is proposed using the technology of determining interface pressure between the seating system and the user to design the seating system. In the first phase, a new seating system design consisting of a single 3D printed structure is proposed. The geometry of the structure and material of the seating system are chosen concerning the effective modification of the mechanical properties and ensuring the breathability of the seating system. In the second phase, the mechanical properties of the flexible structure of the seating system and the material are determined by experimental methods. In the third phase, numerical models are proposed and validated by experimental data. The last phase describes the proposed methodology for optimizing the parameters of the seating system based on the measurement of the user's pressure profile so that the proposed solution ensures a better distribution of the interface pressure between the seat and the user.
