Abstract: The present invention comprises an applicator for the discharge of disinfectant from an aerosol can. The applicator provides an inner and an outer confinement means which permits the discharge of disinfectant from the aerosol can onto a relatively large area being treated.The applicator also comprises an inner confinement adapter which is disposed within the outer confinement means so as to permit a smaller portion of a patient's body to be disinfected. A finger may disposed against the inner confinement apparatus and disinfected appropriately due to the smaller size of the inner confinement means as opposed to the outer confinement means. The flow of disinfectant when the outer confinement means is utilized is not compromised because of the spaced relationship axially between the two confinement rims.
