Abstract
A device 560, for administering multiple single doses of a medicated cream, includes a cartridge 562 having a barrel 564 for containing the cream, a plunger 608 for moving the cream from within the cartridge, and a stem 610 for moving the plunger within the cartridge. A carrier 612 is formed with a cartridge-receiving nest 712 for receiving the barrel 564. A plurality of spaced, transaxial grooves 726, 728, 730 and 732 are formed in the carrier 612 for receiving a flange 572 of the cartridge 562 during the dispensing of multiple, successive, single doses of the cream. The carrier 612 is formed with a pair of resilient ears 750 and 752 and a passage 738 for removably retaining the stem 610 with the carrier while allowing axial movement of the stem.

10. A focused dosimetry device, which comprises:
-
a cartridge formed with a barrel having a passage through the barrel between a proximal end of the barrel and an axially spaced distal end of the barrel;
the barrel having an exterior shape of a prescribed configuration;
a plunger locatable and movable within the passage of the barrel;
a stem having a distal end positionable through the proximal end, and to a position within the passage, of the barrel to facilitate movement of the plunger within the barrel;
the stem formed with a proximal end spaced from the distal end thereof;
the stem formed with an intermediate section along an axis of the stem between the distal end and the proximal end thereof;
the intermediate section of the stem formed with a prescribed cross section;
a carrier formed with a barrel-receiving nest;
means for removably retaining the barrel within the barrel-receiving nest;
means for removably retaining the intermediate section of the stem with the carrier; and
means for allowing the intermediate section of the stem to be moved along the axis of the stem relative to the support member. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 36, 37, 38)

30. A method of dispensing successively two equal amounts of a substance from a distal end of a barrel containing the substance, which comprises the steps of:
-
placing a distal end of a stem through a proximal end of the barrel and into engagement with a plunger within the barrel;
placing the barrel with the stem at a first prescribed location;
moving the stem toward the distal end of, and relative to, the barrel thereby moving the plunger to dispense the substance from the distal end of the barrel;
moving a surface of the stem into engagement with a stop surface after the stem has travelled through a prescribed stem-travel distance, relative to the barrel, whereby a given amount of the substance has been dispensed from the distal end of the barrel;
moving the barrel with the stem to a second prescribed location in a proximal direction away from the first prescribed location whereby the surface of the stem is spaced from the stop surface by a distance equal to the prescribed stem-travel distance;
moving the stem toward the distal end of, and relative to, the barrel to dispense the substance from the distal end of the barrel; and
moving the surface of the stem into engagement with the stop surface after the stem has travelled through the prescribed stem-travel distance whereby an amount of the substance equal to the given amount has been dispensed from the distal end of the barrel. - View Dependent Claims (31, 32, 33, 34, 35)

39. A focused dosimetry device, which comprises:
-
a cartridge formed with a barrel having a passage therethrough between a proximal end thereof and an axially spaced distal end thereof;
the cartridge having an exterior shape of a prescribed configuration;
the cartridge formed with a flange at the distal end thereof;
a plunger locatable and movable within the passage of the barrel;
a stem having a distal end positionable within the barrel to facilitate movement of the plunger within the barrel;
a carrier formed with a cartridge-receiving nest having a shell-like opening which is generally complementary to the prescribed configuration of the exterior shape of the cartridge;
means for retaining the cartridge within the cartridge-receiving nest;
a shelf formed on the carrier extending axially from a proximal end of the cartridge-receiving nest; and
a plurality of spaced flange-receiving slots formed transaxially in the shelf. - View Dependent Claims (40, 41)
