Abstract: A motorization device for a wheelchair may have a positioning arm adapted to be connected to a frame of the wheelchair by at least one lockable joint. A motor block may be operatively connected to the positioning arm by at least one other lockable joint, the motor block including at least a motor and an output roller operatively coupled to the motor, the output roller configured to contact a wheel of the wheelchair to impart torque to the wheel. The positioning arm and the motor block collaborate to provide the motor block with an engaged configuration in which the motor block is configured to biasingly contact a wheel of the wheelchair, and a disengaged configuration in which the motor block is separated from the wheel of the wheelchair.

Abstract: A bag dispensing device comprises a box and a roll of bags, the bags being connected together in the roll. Each bag defines a closed bottom end and an upper end that is closed while the bag is part of the roll but that becomes open once the bag is detached from the roll. The roll of bags is located in the container with at least one leading bag thereof extending out of the container so as to be grasped by the user and detached from the roll when a bag is needed by the user for receiving therein a sample or the like.

Abstract: A device for swabbing a surface and collecting a substance therefrom comprises a handle and a sponge releasably mounted to the handle. The handle includes at least one gripping member adapted to engage the sponge and retain the sponge mounted to the handle in a first position of the gripping member, the gripping member being adapted upon pressure exerted on an actuator to move the gripping member to a sponge-release position thereof for releasing the sponge from the handle. Typically, there are provided two opposed gripping members, wherein the pressure is exerted by a user's fingers on each gripping member and towards one another. The gripping members are actuated to the sponge-release position without requiring that the user substantially moves his/her hand and fingers longitudinally along the handle.

Abstract: A bag dispensing device comprises a box and a roll of bags, the bags being connected together in the roll. Each bag defines a dosed bottom end and an upper end that is dosed while the bag is part of the roll but that becomes open once the bag is detached from the roll. The roll of bags is located in the container with at least one leading bag thereof extending out of the container so as to be grasped by the user and detached from the roll when a bag is needed by the user for receiving therein a sample or the like.
