Abstract
To achieve stable administration of a medicine into a dermis by improving the operability of a device that inserts a microneedle into a skin. An impacting type applicator (1) for a microneedle patch is an applicator that applies a microneedle patch (3) to a skin includes a main body (5), a spring expanding/compressing lever (7), a resilient body (9), a lock mechanism (11), and a piercing switch (13). The spring expanding/compressing lever (7) is movably attached to the main body (5), and the microneedle patch (3) can be attached to a leading end of the spring expanding/compressing lever (7). The resilient body (9) is a member that imparts a biasing force to the spring expanding/compressing lever (7). The lock mechanism (11) is a mechanism that locks the spring expanding/compressing lever (7) in a state where the resilient body (9) exerts the biasing force on the main body (5). The piercing switch (13) is a member that releases the engagement between the lock mechanism (11) and the spring expanding/compressing lever (7). In addition, a biasing force imparting mechanism (121) further imparts a biasing force to the spring expanding/compressing lever (7) in a state where the spring exp…
