Problem Statement <\/h2>\n\n\n\n

Approximately 35 – 80% of nurses sustain back injuries due to patient transfer and handling during their career (Reducing Injuries During Patient Transfer 2007). Therefore, our project aims to find a new mechanism for patient transfers that will minimize the prevalence of back injuries in nurses during lateral patient transfers, while sustaining the safety of the patients.<\/p>\n\n\n\n

Problem Information<\/h2>\n\n\n\n
  • Lateral transfers in patient transfers are often the leading cause of back injuries to healthcare workers<\/li>
  • Incidence rate of back injuries is 28.9 per 10,000 healthcare workers, back injuries due to lateral transfers are 15.8 per 10,000 healthcare workers (Dutta, 2013)<\/li>
  • On average, $15,600 are spent yearly on worker compensation claims for patient handling injuries (Safe Patient Handling, 2009)<\/li>
  • Our goal is to reduce the force needed to move patients, which in turn would reduce the risk of injury for care givers<\/li><\/ul>\n\n\n\n

    Prototyping Process <\/h2>\n\n\n\n

    Our chosen idea, the Safe Patient Transfer Cylinder, utilizes a \u2018rolling mechanism\u2019 and a gear set to perform the lateral transfer. The rolling cylinder gears provide a torsion force that minimizes the force needed to pull patient. The following gallery shows the mechanism we have been optimizing over the semester. <\/p>\n\n\n\n

    Design Key Components<\/h2>\n\n\n\n

    The following list describes the key components in our device:<\/p>\n\n\n\n

    \n
    The Rolling Cylinder <\/summary>
    \n

    The rolling cylinder produces the force required to pull the patient from one surface to another, gears will transmit the torque and amplify force throughout the system<\/p>\n<\/div><\/details><\/div>\n\n\n\n

    The Straps and Hooks<\/summary>
    \n

    The straps transmit the force produced by the cylinder and connect the cylinder to the patient underpad through attached hooks.<\/p>\n<\/div><\/details><\/div>\n\n\n\n

    The Pink Slip and Underpad<\/summary>
    \n

    The Pink Slip is a friction-reducing sheet used to reduce the pulling force. It is placed under the patient’s underpad to reduce the friction coefficient of the system. <\/p>\n<\/div><\/details><\/div>\n\n\n\n

    The Cylinder Stand <\/summary>
    \n

    The cylinder stand supports the rolling cylinder system. It is also connected with locking wheels that provide mobility and stability to the system. <\/p>\n<\/div><\/details><\/div>\n<\/div>\n\n\n\n

    The following image shows the top view of one of the first prototypes we worked on this semester:<\/p>\n\n\n\n

    Final Prototype<\/h2>\n\n\n\n

    Based on our customer feedback that showed preference for a more compact product, we collapsed our cylinder to a smaller length that allows for easier storage and movement. The straps extend in a Y-Shape that connects to the ends of the underpad. Our final prototype utilizes a winch to mimic the rolling gear mechanism, and a utility cart that will act as the cylinder stand. The following image gallery shows our final prototype:<\/p>\n\n\n\n
