摘要： A medication delivery patch that is applied to the skin and activated to deliver a medication or other fluid into or through the skin. The patch may be completely mechanically driven, with no electronic components, for low cost, safety, and reliability. Pressing an activation button may set in motion a sequence of mechanical events that result in a needle exiting the patch into the skin of the user, and flow of fluid from an internal pouch in the patch into the user. When delivery is complete, another sequence of mechanical events may occur to retract the needle from the skin and stop the flow of fluid, and to show a visible indicator that delivery is complete. The patch may contain a fluid channel, such as a microfluidic channel, that controls the rate and time of delivery; this channel can be configured or selected for different medications or use cases.
