Abstract
As a team we are responsible for the Procedural Table Equipment Retrofit project sponsored by the Winnipeg Regional Health Authority. Specifically, the team is tasked with designing a fast deploying footrest and a fluid collection system for the mobile padded procedural table used for dilation and curettage at the Women’s Hospital at the Health Sciences Centre. With the aforementioned features installed, the staff at the Women’s Hospital will gain access to a mobile procedural table capable of being used for dilation and curettage. Having access to said equipment will increase the overall efficiency of operations within the hospital. The footrest the team has designed is made out of 14 Ga. stainless steel wrapped around a support structure composed of welded bar stock. The footrest is attached to the table at the rails of the backrest where a sliding pin mechanism is located to lock the footrest in place. The footrest is lightweight (10kg, ~ 25% lighter than the original) and takes three seconds to deploy the footrest in three simple steps: lift, pull and lower. The sliding pin mechanism consists of two engagement pins and one sliding pin (shoulder bolt), where all three pins are 9.5 mm in diameter. Using FEA and analytical tools, we confirmed that the footrest can safely support the maximum weight of a patient (137 kg) sitting on the footrest, and withstand 25 years of service when subjected to 18.5% of a 137 kg person’s body weight. The fluid collection system the team has designed is composed of a purchased pan that is supported and deployed by C-channels. The fluid collection system is located relative to the patient’s uterus and provides a working surface for the doctor to place his/her tools during surgery. Using FEA and analytical tools, we confirmed that the pan can safely support the maximum weight of 6 kg which includes 2L of fluid and the weight of the surgical tools. Our proposed retrofit design is made entirely of 304 stainless steel, except the shoulder bolts, which are made of 316 stainless. The retrofit will cost $1754.15, which is under budget by […]
