| abstract |
A drug delivery device is described which utilizes gas pressure from free oxygen and hydrogen derived from the electrolysis of water in hydrogels. The gas pressure forces the infusion of the drugs through appropriate means into the body. The rate of electrolysis which produces the gases (oxygen and hydrogen) is controlled by an electric current. This current is activated and controlled by an electronic timer or a biomedical control system (28) which reacts to stimuli related to bodily functions, such as temperature, pH, muscle contractions, electroencephalography, and/or a combination of the above. |
