Specifically designed for use in hospitals and field use. No assembly is necessary for this extremely safe and self-contained finger lancer that combines unrivaled levels of protection from both cross-infection and needle stick injury with superb ease of use thanks to its sophisticated design and construction. After use, the needle automatically retracts for safe disposal. Simply push the plunger covering the lancet into the body of unistik 2 until it clicks. Holding the main body, twist off the lancet cap. Place the end of unistik 2 firmly against the patients finger and press the lever. This releases a spring, causing the needle to stick the finger and then automatically retract after use. Since the needle is never in view, the patient feels more comfortable with this procedure. Each box contains 100 sterile units.
