A method to fabricate, measure and control a physical model for the simulation of human faecal continence is presented. A model rectum and associated soft tissues, based on geometry from an anonymised CT dataset, was fabricated from silicone and showed behavioural realism to ex vivo tissue. Simulated stool matter with similar rheological properties to human faeces was developed. Instrumentation and control hardware are used to regulate injection of simulated stool into the system, define the anorectal angle and monitor stool flow rate, intra-rectal pressure and puborectalis force. A study was then conducted in which simulated stool was introduced to the system for anorectal angles between 80° and 100°. Results obtained from the study give insight into the effect of the anorectal angle on continence. Stool leakage was reduced as the angle became more acute. Conversely, intra-rectal pressure increased. These data demonstrate that the anorectal angle is fundamental in maintaining continence. This work is valuable in helping improve our understanding of the physical behaviour of the faecal system. It has particular relevance facilitating improved technologies to treat or manage severe faecal incontinence.","PeriodicalId":6635,"journal":{"name":"2017 13th IASTED International Conference on Biomedical Engineering (BioMed)","volume":"10 1","pages":"168-175"},"PeriodicalIF":0.0,"publicationDate":"2017-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81834634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The animals are very small and light weight (1–3 cm, 2– 3 g) and the recording data rate is very high (3,5 Mbit/s). Thus, the system has to be extremely small. With state of the art technique it is not possible to set up a wireless implantable system that is suitable for a neonatal mouse. Thus a wired system is developed. For the wired system the connector is a size limiting factor. In wired transmission systems single ended and differential signalling are available. Differential signalling is more robust against noise disturbances, single ended transmission is beneficial with respect to a minimum number of wires and chip area. A detailed comparison of the suitability of both transmission types for wired implantable systems has been performed. A Serial Peripheral Interface connection with Reed Solomon Encoder connection has been implemented. Reed Solomon Error Correction is used to correct the errors occurring on the wired transmission line. Measurements of data rate and error rate for single ended and differential signalling have been performed for long cables (up to 1.8 m). It could be shown that single ended transmission is favourable for the desired application. For the detection and correction of errors occurring on high speed Serial Peripheral Interface Reed Solomon decoding on FPGA was used. This particular decoder design has capability of correcting up to 2 symbol errors on a packet of data composed of 9 symbols where each symbol is 4 bits long. Complete error correction takes about 65 clock cycles on a speed up to 100 MHz.","PeriodicalId":6635,"journal":{"name":"2017 13th IASTED International Conference on Biomedical Engineering (BioMed)","volume":"14 1","pages":"114-120"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79420848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But today only 1 from each 10 people in need have access to AT due to high costs and a lack of awareness, availability, personal training, policy and financing. By 2050, more than 2 billion people will need at least 1 assistive product with many elderly needing 2 or more. Elderly make important contributions to the society. Though some people aged well, other become frail, with a high risk of disease. In this paper, we propose a first approach related the design of AT device. This uses open source technologies and gives a new choice in taking medication dosages. “The Intelligent PillBox” allows the organization of several medication schedules that health disorders presented in elderly need basically. Arduino Mega 2560 was took as the principal controller. This prototype contains; a programmable alarm system with an automatic opening and closing system, an interactive user interface and a notification system through GSM network.

Required adjustments of anticoagulation therapy are most often done manually by using a therapeutic look-up table adapted to patient weight. This process is prone to human errors and an automated solution for calculating the required change and readjusting the individual infusion rate of an anticoagulant therefore would provide benefits. Currently no automated blood anticoagulation system is available and we thus decided to expand an existing ACT measurement device with real-time reporting capabilities. We intercepted the electrical signals to the device's seven segment displays and converted the electrical signals of the numbers using a Raspberry Pi. Then an automated closed-loop heparinization following a look-up table approach as used in clinical practice was implemented. To prove the feasibility of the system, a successful test for 96 hours in an anaesthetized animal was performed. While this study has shown that automatic closed-loop adaptation in a medical environment is feasible, we discuss possible implications of this approach, outline open problems and address issues that need to be solved towards a more automated and better medical care in general.","PeriodicalId":6635,"journal":{"name":"2017 13th IASTED International Conference on Biomedical Engineering (BioMed)","volume":"26 1","pages":"224-228"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83844347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the trauma, the spinal cord withstands an impaction at high velocity. In order to fully assess spinal cord compression, a physical spinal cord surrogate instrumented with bare optical fibers is a promising avenue. The sensing is based on light transmission loss observed in optical fibers subjected to bending. In this paper, the role of the fibers' position within the surrogate is presented and discussed. The closer the fiber from the surface of the spinal cord, the more sensitive it is to small compression magnitude. A threshold value of 15 % was observed for the fiber located at the upper surface of the surrogate. However, this fiber was not able to record compression over 40 %. Another fiber located in the middle of the surrogate was needed to record compression between 40 % to 85 %. Using two fibers allows continuous recording of compressions ranging from 15 % to 85 %. This study shows the relevance of using multiple fibers in order to fully assess the compression of the spinal cord surrogate.","PeriodicalId":6635,"journal":{"name":"2017 13th IASTED International Conference on Biomedical Engineering (BioMed)","volume":"134 1","pages":"229-232"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88887726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
