OVERVIEW
Oral ingestion of pharmaceuticals is considered the safest, most convenient,
and most economical method of administering drugs. However, many pharmaceuticals
cannot be delivered orally because they are too large or too electrically
charged to pass through the small intestine into the bloodstream, or because
they are unable to withstand the environment of the digestive tract. As an
alternative to oral administration, this invention provides a microfluidic
device for delivering a steady infusion of a drug through the skin. The
device may take the form of a thin, transcutaneous patch
that can be worn for extended periods of time. The device includes a
reservoir for storing the drug, and a valve that connects the reservoir to an
output needle inserted into the patient’s skin. A pressure source causes the
drug to flow from the reservoir to the needle. The key advantage of this
design is that the valve can move between the open and closed positions in
response to a predetermined condition in the patient’s physiological fluids,
providing autonomous control of drug flow.
KEY BENEFITS
- Delivers a steady infusion of pharmaceuticals to a patient as needed
- Delivery is autonomously controlled
- Allows closed loop regulation based on physiological signals
- Neither under-medicates nor over-medicates the individual
- Simple to use
- Inexpensive to manufacture
- Useful in the treatment of diseases such as diabetes
