A device for delivering a liquid therapeutic preparation into the body of a patient by injection into or through the skin of the patient comprises a low-profile housing having a bottom surface adapted to be brought into contact with the skin of the patient. A reservoir is disposed within the housing for containing a liquid therapeutic preparation to be administered. An injection needle is disposed generally horizontally in the housing, and is adapted to communicate with the reservoir. The injection needle has a bent injection end which is adapted to project through a needle aperture in the bottom surface of the housing. A movable needle carrier is disposed in the housing for carrying the injection needle and for causing the injection end of the needle to project through the needle aperture upon movement of the needle carrier. The needle carrier and the injection needle are disposed in a side-by-side relationship with the reservoir in the housing in order to minimize the height of the housing above the bottom surface. As a result, the housing is sufficiently low in height to allow the device to be worn inconspicuously under the clothing of the patient.
