The aim of this paper is design, analysis and fabrication of a prototype mechanical lift which operate efficiently, consistently, sholud be easy to handle, multifunctional, cost effective, compact in size. Drafting and drawing of loading and unloading mechanical lift carried out in AUTOCAD with suitable modeling. The analysis of mechanical lift includes total deformation load, reaction forces, buckling and bending failures, equivalent stresses were done in ANSYS Software. Finally this analysis of strength, toughness, elasticity and temperature distribution is carried out in order to check the coherance of the design value.
Abstract 12714: Prevalence and Risk Factors of Peripheral Vascular Disease in Rural India: A cross Sectional Study

PVD is largely undetected due to its silent progression. Ankle brachial index (ABI) is a symptom independent reliable screening tool for PVD in primary care, but remains underused. Our aim was to estimate the burden of PVD in this region and correlate it to various risk factors both quantitatively and qualitatively. Materials and Methods: From an outpatient medical camp in rural India, 100 patients were recruited randomly. They were assessed for symptoms, medical history and risk factor screening that included 11 well known risk factors using a pre formatted questionnaire. ABI was measured by handheld doppler. ABI Results: Based on ABI 55 years (67%), hypertension (66%), smoking (42%) and diabetes mellitus (35%). Mean ABI for hypertensive population is 0.85 (95% CI: 0.83-0.88, P=0.02). Mean ABI for smokers is 0.82 (95% CI:0.79-0.85, P=0.03). Mean ABI for diabet...

Ankle brachial index (ABI) is a good diagnostic tool for PAD in outpatient practice, but remains underused. Materials and methods: Patients were recruited from an outpatient medical camp in rural India, and assessed for symptoms and pre-existing risk factors. Measured ABI 0.9 was considered abnormal and considered PAD. Results: Out of 100 patients recruited, PAD was diagnosed in 57 patients. Associated risk factors were like age >55 years (67%), hypertension (66%), smoking (69%) and diabetes mellitus (35%) were common. Conclusion: PAD is a very common and underdiagnosed illness in rural India. A simple tool like ABI can help diagnosis in underserved areas.
