An apparatus and method for the aseptic delivery of a solution in a wearable form factor is disclosed. A patch pump may include a start button that, upon activation, causes an elastic fluid path to move. The elastic fluid path may include a first end that moves along a first plane to penetrate a solution container as well as a second end that moves, concurrently, along a second plane to penetrate a user's tissue. The elastic fluid path may maintain its flow resistance during the concurrent movement. The patch pump's housing may include a door with an opening configured to enable the second end to penetrate a user via the opening. The door may open when the device is removed from the user such that a portion of the open door may extend further than the second end of the elastic fluid path to prevent exposure of the second end.
