First Claim
1. An improved injection device for self-administering vaccine injections painlessly to a patient, comprising:
- a housing having a base portion;
a needle positioned within the housing, the needle having an injection end having an outside diameter greater than 0.20 mm and less than about 0.38 mm, and being configured for extension to a position wherein the injection end extends through and beyond the base portion;
a reservoir for the vaccine; and
a means for liquid communication between the reservoir and the injection needle;

An injection device that self-administers a painless vaccine injections. The injection device (10) can be secured to the patient'"'"'s skin via a separable base portion (12) of the housing of the device, which can be separated from the device when removing the housing and syringe assemblies for disposal. The injection device can provide a method for substantial amount of time performing the injection procedure, that is relatively simple and inexpensive to perform and operate, and that provides a relatively high degree of safety for both the medical personnel and for the patient.
