APPARATUS FOR INTRODUCING MEDIA INTO THE BODY

摘要

One side of the insulin patch circuit(200) is connected to the collector of transistor(Q1) and the other side is grounded by being connected to the ground terminal(22) used as the power supply terminal. The base of transistor is connected to the base terminal(20) and the power source(Vcc) is connected between the emitter of transistor and the ground terminal. The base terminal and the ground terminal are located on the insulin liquid attaching surface of the substrate(A). The base terminal and the ground terminal that formed on the substrate are formed to overlay with the injected insulin liquid(42) inside the gluing member(B) simultaneously on the substrate. Therefore, the insulin transdermal injector switches the necessary power source for the operation of insulin patch circuit automatically.
