Abstract: A novel embodiment of a pump system, for example, of the type that would be used in a wearable drug delivery system, comprises dual linear-actuated plungers disposed in a pump chamber. The plungers are coupled to a leadscrew having both left-hand and right-hand threads such that rotation of leadscrew in a first direction moves the plungers together and rotation of leadscrew in a second, opposite direction moves the plungers apart. Movement of the plungers away from each other draws one or more doses of a liquid drug from a reservoir into the pump chamber, while movement of the plungers together forces liquid drug to a patient interface for delivery to the patient.

Abstract: The present invention generally provides a device for inserting needles and alleviating the discomfort associated with needle insertion. In certain embodiments, the device is suited for injecting butterfly needles and particularly butterfly needles that are attached to infusion tubing. The patient or caregiver loads a butterfly needle with tubing attached into the base of the drive plunger. The needle with tubing attached is retracted into the housing of the device by retracting the inner plunger. Once retracted, the device is activated and ready to administer a needle into the tissue of a patient. The device is then placed on the location of the skin where injection is desired. The surface that contacts the skin may be textured and may include a contact switch that causes the device to vibrate when slight pressure is applied through contact with the skin.
