  • Medical stretcher having retractable straps
    Patent number: 5492285
    Abstract: A retractable strap apparatus for containing a strap which is commonly used on wheeled emergency tables and stretchers to secure a patient. The strap is wound around a spring loaded retracting mechanism which is contained within a cylindrical strap housing. The strap housing is mounted to a side of a wheeled emergency stretcher or table, and serves to contain the strap so as to prevent the strap from becoming entangled in a wheel of the stretcher or table. A group release for simultaneously releasing multiple straps and a loose strap alarm are also included in the design.
