Using simulation to improve the blood supply chain
Journal of the Operational Research Society, 2007This case study is concerned with analysing policies for managing the blood inventory system in a typical UK hospital supplied by a regional blood centre. The objective of the project is to improve procedures and outcomes by modelling the entire supply chain for that hospital, from donor to recipient.

Modelling and Simulation of Blood Glucose Dynamics
2020 9th Mediterranean Conference on Embedded Computing (MECO), 2020Glucose is a main source of energy in human body and its regulation is controlled by a biological mechanism with organ/cell interactions that are related to glucose-insulin dynamics. This paper presents the model of physiological behaviors of glucose-insulin regulatory mechanism.

Simulation of Blood Vessels for Surgery Simulators
2010 International Conference on Machine Vision and Human-machine Interface, 2010Laparoscopic virtual reality based surgery simulators are becoming a ubiquitous tool in resident training and assessment. Blood vessels on abdominal organ surface are major visual cue of laparoscopic imagery, so it makes sense to develop algorithms of generation of blood vessels.

Simulation of blood flow in microgravity
The American Journal of Surgery, 1992Knowledge of venous, capillary, and arterial blood flow in microgravity is required to modify hemostatic techniques for control of bleeding in traumatic injuries or surgical procedures in space. To simulate human arterial, venous, and capillary bleeding, fresh whole bovine blood was injected by two operators at calculated flow rates (3.5, 7, and 14 mL ...

The development of a blood pressure simulator in KRISS
2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008Blood pressure is defined as the amount of force at unit area which the blood exerts on a wall of a blood vessel. The BP has a clinical importance as the basic index in the medical examination of patients. Especially, the percentage of the hypertensive is more than 15% in an adult population of Korea and hypertension is notorious as 'a silent killer ...

Computational Simulation of the Blood Separation Process
Artificial Organs, 2005Abstract: The aim of this work is to construct a computational fluid dynamics model capable of simulating the quasitransient process of apheresis. To this end a Lagrangian–Eulerian model has been developed which tracks the blood particles within a delineated two‐dimensional flow domain. Within the Eulerian method, the fluid flow conservation equations

Simulated ABO and Rh blood typing
Transfusion, 1995BACKGROUND: Blood typing historically has been used to introduce students to the concepts of immunohematology. Risk of disease transmission has compelled school districts to prohibit the use of human blood in student laboratories. A method is needed that will safely simulate ABO and Rh typing.STUDY DESIGN AND METHODS: A method that uses inorganic salt ...

Numerical Simulation of an Axial Blood Pump
Artificial Organs, 2007Abstract: The axial blood pump with a magnetically suspended impeller is superior to other artificial blood pumps because of its small size. In this article, the distributions of velocity, path line, pressure, and shear stress in the straightener, the rotor, and the diffuser of the axial blood pump, as well as the gap zone were obtained using the ...

Computer simulation analysis of blood alcohol
Journal of Clinical Forensic Medicine, 1995A mathematical model using an iterative algorithm based on the Widmark formula is used to simulate a continuous spectrum of the expected blood alcohol concentration from start of alcohol dosage to time of specific event in numerical and graphic form. Absorption is based on flexible first order rates with provision for an optional good-fit model of the ...

Blood flow simulation and vascular reconstruction
Journal of Biomechanics, 2012In medical practice, bypass grafts are commonly used as an alternative route around strongly stenosed or occluded arteries. In contrast to arterial bifurcations, surgically created anastomosis can be modified with the objective of enabling optimal graft geometry to yield a flow environment that improves its longevity.
