IDENTIFYING POTENTIAL DESIGN INTERVENTIONS FOR HEART-LUNG MACHINES

2023-2-13
Dönertaş, Eren
Heart-lung machine (HLM) overtakes the functions of the heart and lungs during cardiovascular (open-heart) surgeries. Perfusionists, trained personnel, are in charge of operating, maintaining, and calibrating HLMs. There are some risks associated with cardiovascular surgery due to mistakes made by perfusionists. This creates adverse effects for patients undergoing cardiovascular surgery, operators using the device, and hospital management. In this study, the functions and working principles of HLM, the needs and expectations of perfusionists, and the experience of perfusionists during cardiovascular surgeries are examined in order to determine the points that can be improved with design interventions in various hospitals in Turkey during 2021-2022. The primary aim of the study is to decrease the frequency of human-based errors in the usage of HLM during cardiovascular surgeries by enhancing the perfusionist's experiences. Accordingly, literature review is used to become familiar with HLMs, their context and technical considerations. To understand the requirements and expectations of perfusionists regarding the HLMs, user interviews and surveys are carried out. To analyze how perfusionists engage with one another in a given context and pinpoint areas where perfusionists' experiences could be enhanced, user observations are utilized. The research findings are described in a way that is useful to those working on the design of medical devices, product designers, and design researchers.

A cellular automaton based electromechanical model of the heart
Bora, Ceren; Serinağaoğlu Doğrusöz, Yeşim; Tönük, Ergin; Department of Biomedical Engineering (2010)
The heart is a muscular organ which acts as a biomechanical pump. Electrical impulses are generated in specialized cells and flow through the heart myocardium by the ion changes on the cell membrane which is the beginning of both the electrical and the mechanical activity. Both the electrical and the mechanical states of the organ will directly affect the pumping activity. The main motivation of this thesis is to better understand physiological and pathological properties of the heart muscle via studying th...
Computational Approaches to Integrated Modeling of Electrophysiology of the Heart
Paşaoğlu, Özgür; Göktepe, Serdar (2017-09-05)
An accurate understanding of cardiac function necessitates the knowledge of regulation of electromechanical events during a cardiac cycle both on the cellular and organ level. Electrocardiogram (ECG), a recording of the electrical impulses throughout the heart by placing electrodes on specific locations of the body surface, is the most commonly used diagnostic tool measuring the electrical activity of the ventricles and atria through series of waveforms and intervals [1]. ECG is approved to be a key diagnos...
Realization of human gait in virtual fluid environment on a robotic gait trainer for therapeutic purposes
Ertop, Tayfun Efe; Yuksel, Tolga; Konukseven, Erhan İlhan (Elsevier BV, 2018-7)
Patients with disorders such as spinal cord injury, cerebral palsy and stroke can perform full gait when assisted, which progressively helps them regain the ability to walk. A very common way to create assistive effects is aquatic therapy. Aquatic environment also creates resistive effects desired for strength building. In this study, realization of a virtual fluid environment on a robotic gait trainer is presented as an alternative method. A model was created to determine torques and forces acting on the h...
Design of a 3D aligned myocardial tissue construct from biodegradable polyesters
Kenar, H.; KÖSE, GAMZE; Hasırcı, Vasıf Nejat (2010-03-01)
The heart does not regenerate new functional tissue when myocardium dies following coronary artery occlusion, or if it is defective. Ventricular restoration involves excising the infarct and replacing it with a cardiac patch to restore the heart to a more healthy condition. The goal of this study was to design and develop a clinically applicable myocardial patch to replace myocardial infarcts and improve long-term heart function. A basic design composed of 3D microfibrous mats that house mesenchymal stem ce...
Computational analysis for non-invasive detection of stenosis in peripheral arteries
Salman, Huseyin Enes; Yazıcıoğlu, Yiğit (Elsevier BV, 2019-08-01)
Atherosclerosis usually affects the entire cardiovascular system, including peripheral blood vessels. Peripheral arterial stenosis may indicate possible serious vascular disorders related to more vital organs. If peripheral arterial stenosis can be discerned at an early stage, it can serve as a warning sign to take precautions, such as using more invasive diagnostic techniques or adopting a healthier life style. In this study, peripheral regions, such as the thigh, upper arm, and neck are modelled consideri...
