Lancet device

摘要

A novel lancet device is disclosed, and the lancet device is compact and is designed to be held like a writing instrument during use. The device has a trigger relatively close to a firing end so the device can be easily maintained in the desired position while the device is being fired. A cocking knob on the device is rotated one hundred eighty degrees in order to cock the device and prepare the device for use. Only a relatively small amount of rotational force is needed to rotate the cocking knob. The device provides that a lancing needle does not extend and become exposed when the device is cocked. A thumb button is provided on the device, and the thumb button doubles as a depth adjustment knob and an ejector button. The thumb button can be pressed in order to simultaneously eject a tip platform along with the lancing needle, and can be turned in order to set the depth at which the lancing needle will pierce the fingertip when the device is fired. The thumb button can be pushed or rotated without applying an excessive amount of force.
