Pool Accessibility

Pool Accessibility - open-source assistive technology working model by the Alberta community

About this project

A motorized electrical system was vetoed as a solution to this challenge, as the proximity to water and risk of malfunctioning when wet was not desirable. Instead, a simple mechanical lever hoist device was proposed. The only assistance that the user needs is a helper to attach the lever hoist to an anchor point above the user’s head (by use of a rated climbing rope secured around a diving board structure). A sling is positioned underneath the user and attached to the lever hoist. From there, the user can pull the lever until his or her weight is transferred from the wheelchair to the sling, push the wheelchair aside, and then use the lever to lower him or herself in a controlled manner towards the water. The sling/lever-hoist system can also be used for water-to-wheelchair transfers, with the help of an assistant to hold the wheelchair steady.

The challenge

Pool accessibility is a challenge for those in wheelchairs, although swimming is an activity that allows them great mobility and freedom. “Water-wheelchairs” are one method for entering a swimming pool, however these can only be used at facilities that have been built with a ramp leading into the water. Another tool is a large motorized lowering tool that looks like a “back-hoe”. The issue with this is that it is expensive and prone to tipping and falling into the water. The desired solution would be something small and economical that could be utilized at any of the city’s public swimming pools for an individual to self-transfer him or herself into the water.

Who it helps

A duo of need-knowers approached the TOM:Calgary team with an interesting challenge. Both individuals were wheelchair-bound with spinal cord injuries, and both individuals love to swim.
