Desarrollo de prototipo de generación de vacío para tratamiento de presión negativa en heridas crónicas a nivel laboratorio

Abstract

Ingeniería Industrial y de Sistemas

For the development of this project an exploration of literature based on negative pressure in order to increase knowledge about the different types of wounds, healing methods and their classification was performed. Likewise a literature review was performed with respect to different vacuum pump technologies to observe the mechanical components of this. Finally, considering the results of the previous stage, we worked on the design and construction of prototype vacuum pump (Fig. 1) which is composed of an alternate engine Matsushita Electric UDS1401SM current 500W able to exert a negative pressure less than the 5mmHg inside a drain pan with 1 liter. This pressure is regulated by an industrial DIMMER and monitored by a vacuum gauge 30 mmHg RITER; these components are structured through copper pipes from other welding materials. Results No significant violation of the assumptions of the model residuals was found. ANOVA model fit was 26.21%. Outliers one observed in the number 10 shows the level 1028 at the value of that sample was ignored.
