Patent Images
1. An intradermal delivery device for delivering a substance into the skin of a patient, comprising:
- a housing;
a fluid chamber on the housing for containing the substance, said chamber having an outlet for the substance;
a manually actuatable valve member connected to said housing to control the flow of the substance through the outlet, wherein the valve member has a portion exposed to the exterior of the device for digital manipulation between a closed position in which the substance is physically prevented from flowing through the outlet and an open position in which the substance is permitted to flow through the outlet; and
a skin penetrating device on the housing and in fluid communication with the chamber for selectively delivering the substance into the skin of the patient wherein the skin penetrating member has a length of from about 50 microns to about 4,000 microns.
