ABSTRACT:
Disclosed is a lancet injector for use with a lancet and an isolating platform to obtain blood samples for diagnostic purposes in a very safe and accurate manner. This lancet injector makes use of two elastomeric bands to push the lancet forwards and to rapidly withdraw the needle from the skin. The lancet injector also has an interlocking mechanism which completely precludes a lancet from being used more than once and thus obviates accidental misuse which could cause cross-contamination between patients. It further has a mechanism which allows the lancet itself to dislodge the platform thereby causing it to automatically jump forward in front of the needle as it collapses and thus to hood the needle and grip the main body of the lancet. It may also be provided with a window in its housing, through which a three color display panel can be viewed. When the lancet injector is ready for loading, a color is displayed, thus indicating that the injector has been emptied and may now be loaded and then cocked. When cocked, another color is displayed, thus indicating that the injector is ready to be fired. After firing, a third color is displayed to give warning signal that the ejector contains a lancet which has been used and should immediately be ejected. The third color display remains locked until the lancet is completely ejected.
