Injection device for administering a vaccine
First Claim
1. An injection device for self-administering vaccine injections to a patient, comprising:
- a housing having a base portion;
a needle positioned within the housing, the needle having an injection end and having an outside diameter greater than 0.20 mm and less than about 0.38 mm that effects a painless insertion of the needle into the patient, the needle moveable between a first position having its injection end wholly within the housing, and a second position wherein the injection end extends through and beyond the base portion;
a reservoir for the vaccine, in liquid communication with the needle; and
a means for injecting a vaccine from the reservoir through the needle;
a separable base associated with the base portion having a skin-facing surface and an opposed surface, the separable base comprising an adhesive on the skin-facing surface that secures the device to the skin of a patient during the time that the device self-administers the injection of the vaccine to the patient, anda means for separably securing the separable base with the base portion, and a base separating means for selectively separating the separable base from the device while the separable base is secured to the skin.

Abstract
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. The injection device is configured for easy handling, and is manually-powered by the use of the hand or fingers of the medical technician. The device can also comprise a plurality of vaccine syringes at the same time with a single device.

16. An injection device for self-administering vaccine injections 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;
