摘要:
An applicator (100) for applying a microneedle device to a skin surface comprising a first portion (102) comprising a microneedle array (107), and a second portion (104) coupled to the first portion via a connector (106). The connector can be configured to yield or fracture by changing from a first state in which the connector is intact to a second state in which the connector is yielded or fractured when a threshold application force is applied to at least one of the first portion and the second portion in a direction substantially perpendicular with respect to the first portion. A method can include pressing the applicator in a direction substantially perpendicular to the first portion to press the microneedle array into the skin surface until the threshold application force is met or exceeded and the connector is changed to its second state.
