Chair for the bath of Quadriplegics

摘要

The following project involves a study about the hygienic process in the bath of quadriplegic people. The main problem of the currently available equipment is the caregiver's necessary effort during the act, since the patient does not present movement of the upper and lower limbs, thus implying a total dependence of the person with quadriplegia on his caregiver. The research proposes a remodeling of the most common model of bath chair used in the domestic and hospital environment. The treated device allows the inclination of the sanitary seat coupled to the chair using the support of a manual hydraulic piston, facilitating access to the patient's intimate areas and, consequently, better hygiene - this feature located below the seat, coupled to the frame on the front. Also, the supports for the patient's feet and arms modeled, allowing the abductor movement of the lower and upper limbs, contributing to the visualization and access to the areas, emphasizing that these require careful cleaning, as they function as an outlet for liquids and excrement of the human body. It was possible to remodel the bath device in Autodesk Inventor 2018 software. The material selected for the construction of the structure was Steel 1020, which was selected based on the physical, chemical, and biological agents that could come into contact with the chair. The structure is resistant to safely support the patient and not to suffer significant wear over time.
