Patent number: 11938067Abstract: A patient containment system for securing a patient to a patient transport apparatus, comprising a first lower strap and a second lower strap. Each of the first lower strap and the second lower strap have a thigh region, a waist region, and a connection region arranged between the thigh region and the waist region. A first connector is coupled to the connection region of the first lower strap. A second connector is coupled to the connection region of the second lower strap, and is configured to releasably attach to the first connector to at least partially limit movement of the first lower strap relative to the second lower strap. The connection region defines a connection width, and the thigh region defines a thigh width larger than the connection width.Type: GrantFiled: December 23, 2020Date of Patent: March 26, 2024Assignee: Stryker CorporationInventors: Daniel V.
