Regulator device for drug patch
Embodiments are disclosed of a method of controlling timing and/or dosage of a transdermal drug patch. For example, a control device operative to move the patch to one or more of a plurality of operational relationships with a skin of a patient, including being fully engaged with the skin, partially engaged with the skin, and disengaged with the skin. The device may include a roller that peels a patch on and off the skin. Optionally a convention patch is used. In some embodiments a patch and/or an adaptor has a mobile zone and an immobile zone. In some embodiments, an active surface of the patch fully contacts the skin in an engaged state. For example the patch may be attached to the device on a passive portion thereof.
1. A drug patch device comprising:
a roller rotationally mounted in a housing and linearly movable along a track in said housing, wherein said roller comprises a drug patch interface member capable of engaging and disengaging a drug patch via an open face formed in said housing and rotation of said roller rolls up or unrolls said drug patch onto or off said roller, and further comprising a tongue near said roller operative to catch and remove a liner from the drug patch.
2. The drug patch device according to claim 1 , further comprising a drug patch wound on said roller.
3. The drug patch device according to claim 2 , wherein said drug patch comprises a skin interface layer and a protective liner, wherein said protective liner contacts said roller.
4. The drug patch device according to claim 1 , wherein said drug patch interface member comprises a portion of a shaft of said roller.
5. The drug patch device according to claim 1 , wherein said drug patch interface member comprises a substrate coupled to said roller.
6. The drug patch device according to claim 5 , wherein said substrate comprises an adhesive foil.
7. The drug patch device according to claim 1 , wherein said track comprises a plurality of drive teeth that engage said roller.
8. The drug patch device according to claim 7 , wherein a distance between said teeth changes as said roller moves along said track.
9. The drug patch device according to claim 1 , wherein said roller is coupled to a direct drive driver.
10. The drug patch device according to claim 1 , wherein said roller is coupled to a driver via a transmission.
11. The drug patch device according to claim 1 , wherein said roller is coupled to a driver located inside said roller.
12. The drug patch device according to claim 1 , wherein said tongue is positioned near said roller just before drug patch begins to wrap around said roller.
13. A method of manipulating a drug patch comprising:
using said drug patch device of claim 1 to engage or disengage a drug patch via said open face, wherein rotation of said roller rolls up or unrolls said drug patch onto or off said roller.
14. The method according to claim 13 , comprising placing said open face of said housing over said drug patch and at least partially winding said drug patch around said roller.
15. The method according to claim 14 , comprising synchronizing rotation of said roller with a rate of uptake of said drug patch onto said roller.
16. The method according to claim 13 , comprising storing said drug patch at least partially wound around said roller.
17. The method according to claim 13 , comprising placing said open face of said housing on skin and unrolling at least a portion of said drug patch from said roller onto said skin.
18. The drug patch device according to claim 1 , further comprising catching and removing a liner mounted on said drug patch so that said drug patch rolls onto said roller without the liner.
