Abstract:
A cassette for storing and insertion of a solid medicine peg, said cassette comprising a housing at least one unit having a first bore (2) accommodating the medicine peg (3) and having a diameter corresponding to the diameter of the peg (3), a second bore (4) in coaxial extension of the first bore (2) and having a diameter larger than the diameter of the first bore (2), an inserter comprising an inserter shaft (5) fitting into the first bore (2) and a guiding head (6) connected to the inserter shaft (5) in coaxial extension of the inserter shaft and fitting into the second bore, the inserter shaft (5) having a distal end adjacent to a proximal end of the peg (3) and a proximal end connected to a distal end of the guiding head (6) which forms at its proximal end an anvil (7), the second bore (4) having a length so that the distal end of the inserter shaft (5) is moved to a position extending beyond the distal end of the housing a distance corresponding to a wanted insertion depth for the peg when the distal end of the guiding head is moved to a bottom of the second bore, wherein the head (6) of the inserter fits into the second bore with a press fitting which provides a diffusion tight sealing of the proximal end of the unit, and wherein the distal end of the unit is closed by a membrane diffusion tightly sealing the distal end of the unit.
