Title
(EN) Single-use skin pricking device
Abstract
(EN)
A single-use skin pricking device 7 comprises a housing 8, a lancet 1 disposed within the housing 8, a spring biasing means 11 coupled between the housing 8 and the lancet 1, and a trigger 12 mounted to the housing 8. The trigger 12 is releasably coupled to the lancet 1 and the mounting allows relative movement between the housing 8 and the trigger 12. Movement of the trigger 12 in a first direction moves the lancet 1 to compress the spring 11, and then causes release of the lancet 1 from the trigger 12. The spring then drives the lancet 1 in a direction opposite to the first direction. The lancet 1 follows a U shaped guide track 10 in the housing 8, and the trigger 12 has an opening 13 through which a needle (3, figure 1) of the lancet 1 is projected. Once the device has been fired the lancet 1 is fully retracted into the housing 8. The mechanism allows the device to be activated by a single movement in one direction (pushing the trigger onto the skin) and thus using only one hand.
