Abstract

In a preferred embodiment of the invention, a transdermal patch holder is provided for making possible an ascertaining of drug release rate of a transdermal patch mountable thereon. The holder includes upper and lower spaced-apart aligned annular adapter disc structures forming aligned through-spaces. An upper surface of the lower disc structure has a centrally positioned stepped indentation forming a recess space seatable of the transdermal patch. The lower surface of the upper disc structure has a centrally positioned stepped downwardly-extending projection of slightly lesser cross-section than the cross-section of the recess space and is adapted to downwardly press upon an upper surface of a seated transdermal patch when the upper disc structure is intermittently in a latched state of being latched to the lower disc structure. A latching mechanism provided by outer circumscribing upright edges at each of opposite sides of each of the upper and lower disc structures has spaced-apart cut-aways forming a radially outwardly extending lateral projection therebetween, and lateral projections of the upper and lower disc structures aligned and having elastic annular bands intermittently mounted thereon securable of the upper and lower disc structures in face to face relationship. A transdermal patch is mountable and may be thereby held therebetween, with a handle-tab of the patch being seatable in and extendable through a laterally extending channel to laterally exterior space.
