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. Two trigger buttons in the housing of the device may be depressed to eject the needle at an angle essentially perpendicular to the surface of the skin into the tissue of the patient concurrently with the textured pads contacting the skin and vibrating, distracting the patient from the needle insertion. The inner plunger of the device is then depressed toward the surface of the skin to release the needle from the device. The wings and body of the butterfly may be secured to the skin, for example, with an adhesive such as tape. ## Claims ### Claim 1 A device for administering a needle to a subject, comprising: a housing comprising a shell with a distal opening and a proximal opening, a distal surface disposed at least partially about the distal opening; a drive plunger occupying the space defined by the shell of the housing and in shifting engagement with the housing, wherein the drive plunger has a proximal end with a handle extending from the proximal opening of the housing and a distal end dimensioned to receive and deliver the needle; a drive spring associated with the drive plunger such that when the handle is retracted proximally relative to the housing, the drive spring compresses and when the drive plunger is released, the drive plunger travels distally from the force of the drive spring; and a component for relieving discomfort associated with injecting the needle to the subject receiving the injection, the component comprising a vibrator motor and power source associated with the housing such that the power source supplies power to the vibrator motor when the motor is activated; wherein the needle is a butterfly needle having wings, the housing further comprising two opposing channels extending from the distal opening towards the proximal opening, the distal end of the drive plunger further including recessions for receiving the wings of the butterfly needle, the recessions aligned to the channels of the housing to permit each wing of the butterfly needle to extend from the housing. ### Claim 2 (depends on 1) The device of claim 1, wherein the component for relieving the discomfort to the patient further includes a textured pad on the distal surface of the. ### Claim 3 (depends on 1) The device of claim 1, further comprising a stop to hold the drive spring in a retracted position. ### Claim 4 (depends on 3) The device of claim 3, wherein the stop is a button extending from the surface of the drive plunger, depression of the button releasing the drive plunger from its retracted state. ### Claim 5 (depends on 1) The device of claim 1, wherein when the drive plunger is released, the needle is injected into the skin of the subject. ### Claim 6 (depends on 5) The device of claim 5, wherein when the needle is injected into the skin of the subject, the distal end of the drive plunger releases the needle from the device. ### Claim 7 (depends on 1) The device of claim 1, wherein the needle is attached to infusion tubing, the housing further comprising a tubing channel extending from the distal opening towards the proximal opening, the infusion tubing attached to the needle extending through the tubing channel. ### Claim 8 A device for administering a butterfly needle having wings to a subject, comprising: a housing comprising a shell with a distal opening and a proximal opening, with two opposing channels extending from the distal opening towards the proximal opening, a distal surface disposed at least partially about the distal opening; a drive plunger occupying the space defined by the shell of the housing and in shifting engagement with the housing, wherein the drive plunger has a proximal end with a handle extending from the proximal opening of the housing and a distal end dimensioned to receive and deliver a needle, the distal end further including recessions for receiving the wings of the butterfly needle, the recessions aligned to the channels of the housing to permit each wing of the butterfly needle to extend from the housing; a drive spring associated with the drive plunger such that when the handle is retracted proximally relative to the housing, the drive spring compresses and when the drive plunger is released, the drive plunger travels distally from the force of the drive spring; and a component for relieving discomfort associated with injecting a needle to the subject receiving the injection. ### Claim 9 (depends on 8) The device of claim 8, wherein the recessions in the distal end of the drive plunger are dimensioned to hold the butterfly needle firmly in place. ### Claim 10 (depends on 8) The device of claim 8, wherein the component for relieving the discomfort to the patient is selected from one or more of: a textured pad on the distal surface of the housing and a vibrator component comprising a vibrator motor and power source associated with the housing such that the power source supplies power to the vibrator motor when the motor is activated. ### Claim 11 (depends on 8) The device of claim 8, wherein when the drive plunger is released, the butterfly needle is injected into the skin of the subject. ### Claim 12 (depends on 11) The device of claim 11, wherein when the needle is injected into the skin of the subject, the distal end of the drive plunger releases the needle from the device. ### Claim 13 (depends on 8) The device of claim 8, wherein the needle is attached to infusion tubing, the housing further comprising a tubing channel extending from the distal opening towards the proximal opening, the infusion tubing attached to the needle extending through the tubing channel. ### Claim 14 (depends on 8) The device of claim 8, wherein the distal surface of the housing is divided into at least 2 distinct parts with the channels of the housing therebetween. ### Claim 15 (depends on 1) The device of claim 1, wherein the distal surface of the housing is divided into at least 2 distinct parts with the channels of the housing therebetween.
