Abstract
A compact single use applicator is disclosed having a dry medication (e.g, a dehydrated or lyophilized astringent disinfectant that is adapted to treat ache and has been reduced to a powder) stored in a flexible mixing chamber. Liquid diluents are stored in first and second flexible chambers. Fluid communication between the diluents in the first and second chambers and the dry medication in the mixing chamber is blocked by normally closed, pressure activated fluid paths. By compressing the first and second chambers, corresponding hydraulic pressures are generated in the diluents thereof which force open the pressure activated paths. Accordingly, the diluents in the first and second chambers are introduced under pressure to the dry medication in the mixing chamber to rehydrate and reactivate the medication. The reconstituted multi-constituent liquid medication is then supplied from the mixing chamber to a dispensing chamber via another normally closed pressure activated fluid path. The liquid medication is absorbed by an applicator pad, or the like, that is surrounded by the dispensing chamber, whereby the medication can be applied via an opening through the dispensing chamber to a relatively wide tissue area as a topical treatment for ache or other skin disorder.
