Benefits of technology

[0010] Many people consider an injection (at best) unpleasant and (at worst) a painful encounter, no matter how well the nurse or doctor administers the shot This is because most shots are given subcutaneously or intramuscularly, reaching deep enough into the skin to hit nerves. Part of the skin's job is to sense danger in the environment through nerve cells, and it is richly endowed with these cells—a single square inch of skin contains approximately 1,300 nerve endings. Since most injections are given subcutaneously or intramuscularly, thereby delivering drugs to be absorbed i

Embodiment Construction

[0026] The following description is of preferred embodiments.

[0027] In one aspect of the present invention a novel type of drug reservoir is provided. The drug reservoir comprises a fillable bladder. The reservoir is formed between two layers of plastic film. The two layers can be formed from two sheets or from one sheet folded in half. When two sheets are used, the sheets may comprise the same material, thickness, etc. or they may be two different types of sheets.

[0028] The present invention provides for a drug delivery device incorporating a disposable reservoir. The device may be provided as a single-use, disposable device or a multi-use device. The device comprises a housing that has an upper end and a lower end. As used herein, the term “upper” is used to refer to the surface furthest away from an individual skin and the term “lower” is used to refer to the part of the device that contacts a patient's skin. An actuator is mounted at the top of the housing. The actuator is use...

Abstract

A novel device and method for intradermal delivery of an active agent is provided. The device comprises a housing which contains a reservoir chamber. A flexible reservoir containing the active agent is placed in the chamber. Upon pressure on an actuator the active agents is delivered via a hollow needle to the skin.

Description

FIELD OF INVENTION [0001] The present invention relates to drug delivery devices and methods of delivering a drug intradermally. In particular, the present invention relates to intradermal delivery of a liquid drug. BACKGROUND OF THE INVENTION [0002] There has long been a desire to deliver drugs intradermally. The skin comprises two layers, the outer or upper surface called the epidermis, and the internal surface referred to as the dermis. The epidermis does not contain any blood vessels and it is dependent on the underlying dermis for nutrient delivery and waste disposal via diffusion. The inner layer, the dermis, is composed of two layers, the more superficial papillary dermis and the deeper reticular dermis. The papillary dermis is thinner and consists primarily of loose connective tissue containing small capillaries, elastic fibers, reticular fibers and some collagen. The deeper reticular dermis consists of a thicker connective tissue containing larger blood vessels, interlaced ...
