The mechanical model is based on a simplification of the musculoskeletal shoulder. The system consist in an arm with forces: the arm weight, six scapulo-humeral muscles and the reaction at the glenohumeral joint, wich was considered as a spherical joint. We use the mathematic model proposed by Terrier A. The prototype will emulate the basic movements of the shoulder (flexion-extension and abdution-adution). The construction will be made with the selected materials based on the results obtained through a virtual effort analysis. The components of the preliminary prototype have been test with forces on the virtual analysis. The prosthesis design of the glenohumeral joint match with the motion parameters proposed and it have 3 degrees of freedom.","PeriodicalId":151015,"journal":{"name":"2013 Pan American Health Care Exchanges (PAHCE)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122666466","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 system was subjected to tests in order to validate its precision and accuracy. The accuracy of intracorporeal length has an absolute error of less than ±1.5 mm, and a variation of ±1 mm in its precision (99%), whereas the angles can be measured with a precision of ±1° (99%).","PeriodicalId":151015,"journal":{"name":"2013 Pan American Health Care Exchanges (PAHCE)","volume":"584 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123128026","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}

To date, there are many diagnostic methods for determining the psychoacoustic characteristics of the disease, none have been merely when definitive diagnosis of a lens, on the contrary depends largely on the patient's description, making diagnosis and subjective clinical unreliability having no actual physical record of it. Therefore, it was decided to test the hypothesis proposed by Dr. Ramiro Vergara, which states that all have a sound source Tinnitus real, and design and implement a biomedical equipment capable of capturing the sound signals generated in the ear of patients with this Acufenometro condition called Objective.

Autologous chondrocyte implantation (ACI) is a technique based in obtaining autogenous chondrocytes from a cartilage biopsy. After culturing, the cells are seeded onto biodegradable scaffolds that provide the environment required for growing them. The grown chondrocytes replace and remodel the scaffold to produce artificial cartilage used for grafting. Indeed, surgical procedures based on artificial tissue have been already marketed in USA and Europe (Carticel®, BioCart). Unfortunately, the clinical implementation of ACI has been limited by its high cost: Colombian patients who need ACI must travel to USA, Italy or Israel where authorized cell processing facilities are located. Therefore, there is a need for the development of in-site production of tissue engineered cartilage to provide patients of all socioeconomic status with ACI at a reasonable cost. A commonly biomaterial used to manufacture scaffolds for engineering artificial cartilage is collagen type II, a major component of the cartilage extracellular matrix. In this work scaffolds were produced using pure collagen type II isolated from bovine trachea. The microstructure of them was also studied.","PeriodicalId":151015,"journal":{"name":"2013 Pan American Health Care Exchanges (PAHCE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130838960","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}

Commercial simulators are not able to reproduce all signal behavior; thereby, we developed a light based emulator able to provide different signal patterns using colorimetry and spectrophotometry. Several parameters are configurable according to customer requirements. Amplitude and frequency are controlled by the usage of a DC motor, a coloured band, a mechanical structure, and, particularly, an oximetry probe. The prototype emulator provides basic signals such as sine, square, triangle, or complex physiological signals, as photoplethysmograms (PPG) and Electrocardiograms (ECG). Other complex patterns include sources of error and chaotic characteristics such as noise or motion artifact, can be simulated. The device may be used to analyze, determine and verify data acquisition platforms, medical instrumentation, training tool interfaces, among others. Preliminary results have contributed to the construction and validation of complex patterns; corroborating practicality, operability and reliability of the proposed product and reducing developing time on representations.","PeriodicalId":151015,"journal":{"name":"2013 Pan American Health Care Exchanges (PAHCE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130995193","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}

This movement was made in four cases, from the subject standing up to the subject seated.
