Abstract
A transdermal delivery apparatus for delivering specific desired quantities of cream-base medicament or any flowable composition is disclosed. The apparatus comprises a revolving platform, a threaded screw-complex, a house, an applicator pad, and a safety cap. The revolving platform produces audible and tactile sensations upon interaction with projections from the house. The threaded screw-complex interacts with an elevator to transport the medicament upwards. The house confines an inner chamber to store the medicament. The applicator pad comprises a center outlet where the composition exits the chamber.
Claims20
A cavity applicator, comprising:
- A barrel comprising:
- an inner cavity configured to contain a medication;
- an inner wall forming the inner cavity;
- and
- a plurality of feedback segments disposed along the inner wall;
- a plunger disposed within the barrel, the plunger configured to move within the inner cavity of the barrel and push the medication out an opening at a first end of the barrel, the plunger comprising:
- a body;
- a plurality of dosing tabs disposed along a portion of the body of the plunger;
- a plurality of dosing segments, each of the dosing segments located adjacent to one or more dosing tabs of the plurality of dosing tab, each of the plurality of dosing segments comprising a length corresponding to a predetermined amount of medication, such that when the plunger is moved through the barrel a distance equal to the length of the dosing segment, the predetermined amount of medication is dispensed through the opening at the first end of the barrel;
- and
- a piston seal located proximate the first end of the plunger, the piston seal configured to contact and create a seal with the inner wall of the barrel, the piston seal configured to provide feedback through the plunger or the barrel to a user when contacting or passing one feedback segment of the plurality of feedback segments, wherein the feedback comprises at least one of tactile feedback and audible feedback.
A method for dispensing medication, the method comprising:
- rotating a rotatable platform relative to a housing of an applicator;
- engaging a plurality of inner tabs extending from the housing with a first plurality of contacts extending from the rotatable platform;
- conveying feedback to the user, the feedback caused by the engagement of the plurality of inner tabs with the first plurality of contacts;
- engaging a plurality of outer tabs extending from the housing with a second plurality of contacts extending from the rotatable platform;
- conveying feedback to the user, the feedback caused by the engagement of the plurality of outer tabs with the second plurality of contacts;
- rotating a screw shaft extending through the rotatable platform and within the housing;
- moving an elevator connected to the screw shaft upwards through the housing;
- and
- pushing medication contained within the housing out through a top of the housing.
An apparatus comprising:
- a housing comprising:
- a first plurality of protrusions extending from the housing located radially around a centerline of the housing;
- and
- a second plurality of protrusions extending from the housing located radially around the centerline of the housing;
- a rotatable platform secured to the housing, the rotatable platform comprising:
- a first plurality of contacts extending from a first surface of the rotatable platform, the first plurality of contacts configured to interact with the first plurality of protrusions as the rotatable platform is rotated relative to the housing;
- and
- a second plurality of contacts extending from a second surface of the rotatable platform, the second plurality of contacts configured to interact with the second plurality of protrusions as the rotatable platform is rotated relative to the housing.
