The paper offers a survey of some major simulation and control issues associated with the development of an Artificial Pancreas . The main topics include the role of large-scale simulation models used to carry out in silico trials, the discussion of the specific features of Dear Sir, There is an increasing body of evidence to suggest that patients with diabetes mellitus have accelerated atherosclerotic vascular disease which seems primarily dependent on endothelial injury [l]. An increased sensitivity to platelet aggregating agents
A closed loop implantable artificial pancreas using thin film nitinol MEMS pumps
free download
To prevent the onset of serious pathologies diabetics must maintain extremely close control over their glucose levels which requires as many as eight blood samplings a day, an onerous task. A long sought solution is to have glucose monitored by an implantable sensor
A closed-loop artificial pancreas based on MPC: human-friendly identification and automatic meal disturbance rejection
free download
Type 1 diabetes is characterized by a lack of insulin production from the pancreas, causing high blood glucose concentrations and requiring external insulin infusion to regulate blood glucose. A novel procedure of human-friendly identification testing using multisine inputs is
Real-time detection of Glucose Sensor and Insulin Pump Faults in an Artificial Pancreas .
free download
Sensors for real-time continuous glucose monitoring (CGM) and pumps for continuous subcutaneous insulin infusion (CSII) have opened new scenarios for Type 1 diabetes treatment, including the development of an Artificial Pancreas , a minimally invasive device
Glucagon and blood glucose: Insights from artificial pancreas studies
free download
The central role of insulin in the pathogenesis of diabetes has been recognized since the classical experiments of Banting and Best in 1921. Subsequent studies, however, have clearly shown that other hormones also contribute to the regulation of blood glucose. The
A constrained model predictive controller for an artificial pancreas
free download
A Constrained Model Predictive Control (CMPC) approach for regulating blood-glucose levels in people with type 1 Diabetes is proposed. The controller uses the past suggested insulin, the subcutaneous glucose level, and an estimation of the carbohydrate amount of
Hybrid online sensor error detection and functional redundancy for artificial pancreas control systems
free download
Artificial pancreas (AP) control systems rely on signals from glucose sensors to collect glucose concentration (GC) information from people with Type 1 diabetes and compute insulin infusion rates to maintain GC within a desired range. Sensor performance is often
From pancreatic extracts to artificial pancreas : history, science and controversies about the discovery of the pancreatic antidiabetic hormone. IV: Frederick
free download
Most relevant pioneer works were carried out by Georg L. Zuelzer and Israel S. Kleiner. On June 21 and June 22, 1906, Zuelzer injected subcutaneously his pancreatic extract to a comatose adult diabetic subject who showed an impressive transient recovery. As there was
Design and development of a mechatronic system for noninvasive refilling of implantable artificial pancreas
free download
The aim of this study is to contribute to the ad-vancement of the mechatronic implantable artificial organs field by demonstrating the feasibility of a mechatronic refilling module to be used with implantable artificial organs (and particularly suitable for an artificial pancreas )
Live demonstration: A handheld Bio-inspired Artificial pancreas for treatment of diabetes
free download
Good control of glucose in diabetes requires minimisation of high and low blood glucose excursions and is critical to reducing the incidence of complications and improving quality of life. A closedloop insulin delivery system consisting of a glucose sensor, a controller and an
Actuator fault tolerant control for an artificial pancreas
free download
With recent advances in continuous glucose sensors and portable insulin pumps, the concept of an artificial pancreas is now feasible. However, due to continuous operation, the actuator in this system could fail in some degree. In this sense, this paper addresses model Five years ago, we started to reestablish normoglycemia in diabetics by technical means (1-2). The artificial endocrine pancreas, developed at the University of Ulm in collaboration with Mr. AH Clemens from Life Science Instruments, Miles Laboratories, Inc., Elkhart, Ind. (USA), is
The artificial pancreas in 2017: The year of transition from research to clinical practice
free download
In this trial, the insulin requirements of each participant (basal rate settings and carbohydrate ratio) were adapted every week using an adaptation algorithm. Consistent with the pilot nature of this study, the adaptation of these critical parameters had to be confirmed by a
A bio- artificial pancreas created using cell encapsulation in self-assembled microcontainers on alginate sheet
free download
This paper presents a bio- artificial pancreas fabricated with self-assembled, precisely structured 3D microcontainers on a rolled-up alginate sheet. We utilize a novel 3D membrane approach developed in our laboratory to package pancreatic βcells so that they
