Abstract: Various exemplary liquid drug pumps including user feedback indicating pump orientation are provided. In general, a pump configured to deliver a liquid drug to a patient includes a user interface configured to indicate an orientation of the pump. The pump also includes a reservoir configured to contain the drug therein, a conduit configured to receive the drug therein from the reservoir, a needle or cannula in fluid communication with the conduit and configured to deliver the drug therethrough to a patient wearing the pump, a fluid path fluidly connecting the reservoir and the needle or cannula, and a pumping assembly configured to pump the fluid through the fluid path from the reservoir to the needle or cannula. The user interface indicating the pump's orientation allows a user of the pump to know whether or not the pump is in a desired orientation for delivery of the drug to the patient.

Abstract: Various exemplary liquid drug pumps with a flexible drug reservoir are provided. In general, a pump includes a flexible reservoir configured to contain a liquid drug therein for delivery to a patient wearing the pump. The reservoir is configured to be filled with the drug from a drug storage container, which can either be external to the pump or disposed within the pump.

Abstract: Various exemplary methods, systems, and devices for injection pump needle mechanics are provided.

Abstract: Various exemplary pumps with orientation independent liquid drug accessibility are provided. In general, a pump includes a reservoir configured to contain a liquid drug therein, a conduit configured to receive the drug therein from the reservoir, and a needle in fluid communication with the conduit and configured to deliver the drug therethrough to a patient wearing the pump. The conduit includes a mechanism configured to ensure that the conduit is in complete communication with the drug in the reservoir at least when the conduit is receiving the drug therein from the reservoir regardless of the patients orientation. In one exemplary embodiment, the mechanism includes a weight attached to the conduit. In another exemplary embodiment, the mechanism includes a fork at a free end of the conduit that is located in the reservoir.
