Abstract:
A method for making a laminated carrier film for use in releasing interstitial fluid from skin for collection or measurement, comprising:providing a printhead having an orifice and a reservoir containing a meltable absorber substance, the printhead being capable in response to electrical signals, to eject droplets of said meltable absorber substance from the orifice; supporting a carrier film having a series of spaced apart openings for a meltable absorber substance on a support base, in close proximity to the printhead, whereby the spaced apart openings on the carrier film can be positioned relative to the orifice to receive absorber substance droplets ejected from the printhead; filling the spaced apart openings of the carrier film with meltable absorber substance ejected from the printhead; and covering the carrier film on one side with a clear polymer film strip selected to allow laser energy to pass through the clear polymer film in order to reach the meltable absorber substance inside the openings.
