The GD500 lancing device is reusable 
lancing device for the single user. It could 
automatically inject the lancet into and 
retract it from the fingertip to obtain a 
capillary blood sample for glucose 
monitoring or other test that require one or 
two drops of blood. 
A depth adjustable cap allows the best depth 
of skin penetration for each individual user.

Special Features

- Special safety design: when the cap is open, the trigger will be relieved automatically which prevents 

you from being pricked in case you accidentally press the release button.

- Lancet eject function: press the release button in one hand and pull on the plunger in the other hand 

will safely eject the used lancet which prevents you from being pricked  when the cap is open. ( please 
refer to the figure of step10 )

- Less pain pricking: exact and vibration free guidance of the lancet makes almost painless feeling when 

you get the blood sample.

- Proper spring force: allow user to pull on the plunger for pricking easily.
- Clear indications of depth penetration: allow user to adjust for proper sample volume easily.
