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 including a Belleville spring (124,128) exerts pressure on the liquid therapeutic preparation to discharge it from the reservoir at a relatively constant rate. The device includes an injection needle (144) adapted to communicate with the reservoir (118) and to project from the housing in order to inject the liquid therapeutic preparation into or through the skin of the patient.
