Abstract
Abstract A medical injection device, such as a pen-type injector has a microprocessor coupled to the injector that records the date, the time, and the amount of each injection. The microprocessor may also be coupled to a display to indicate the amount of medication to be injected. The medical injection device can also be coupled with a blood characteristic monitor to analyze characteristics of the blood. This provides a single, all-in-one device that performs a variety of functions, and requires only a minimum of space. The medical injection device may also use a disposable needle that substantially eliminates or reduces bleeding from an opening in the skin at the injection site.
