Plunger () is in a first position, having first notch () engaged with ridge (). After activation, wherein plunger () is in a second position such that second notch () is engaged with ridge (). Here, bottom () of plunger () extends below first major surface () of housing () and has ejected microarray patch ().

Microarray applicator

Microarray applicator (), a method of using the same and a kit. The microarray applicator comprising a housing (), a microarray holder () and a plunger (). The plunger comprising a first ridge () and a second ridge (), both engagable to a notch (). Microarray applicator does not uses springs or pre-biased mechanisms to reduce costs.

An applicator and method for applying a microneedle device to skin. The applicator can include a microneedle device and a housing configured to house the microneedle device. The housing can have a first surface configured to be positioned toward the skin. The applicator can include (i) an unactuated state in which the microneedle device is located within the housing and does not extend beyond the first surface of the housing, and (ii) an actuated state in which at least a portion of the microneedle device extends beyond the first surface of the housing. The applicator can further include a locking mechanism configured to lock the applicator in the actuated state. The method can include positioning the first surface of the housing of the applicator adjacent the skin; actuating the applicator to cause the applicator to change to the actuated state; and locking the applicator in the actuated state.
