Abstract

A lancet belt has a first belt tape with a longitudinal axis and an adhesion material disposed on an adhesion side of the tape. A second belt tape has a longitudinal axis disposed on the adhesion side of the first tape with the longitudinal axes of the first belt tape and the second belt tape being substantially parallel. A plurality of lancets are disposed between the first belt tape and the second belt tape. Longitudinal axes of the lancets are substantially orthogonal to the longitudinal axes of the first and second belt tapes.
