Abstract
Propellable apparatus for use in sampling for the contact transfer of a chemical residue on a surface comprising a frame having shoulders with movable supports at one end thereof and having mounted on the other end a roller having thereon a cylindrical layer of a resilient material with chemical residue contact transfer absorption properties similar to human skin, the roller being pivotably mounted such that a desired constant pressure, based on the weight of the roller, is maintained regardless of pressure applied to the shoulder to propel the apparatus.
Claim:
Propellable apparatus for use in sampling for the contact transfer of chemical residue on a surface possibly containing a chemical residue so as to determine human's dermal exposure to said chemical residue by coming into dermal contact with said surface, comprising frame means comprising shoulder means and leg means pivotably attached at one end thereof to said shoulder means, said shoulder means mounted on movable supports, roller means rotably attached to said leg means at a second end thereof, propelling means attached to said shoulder means to propel said apparatus, and a cylindrical layer of a resilient material, which has chemical residue contact transfer absorption properties similar to human skin removably mounted on said roller means, whereby pressure, applied to said shoulder means is transmitted to said movable supports and not said roller means and the pressure of said roller means on said surface is based on the weight of said roller means and is maintained constant regardless of the pressure applied to said shoulder means. |
