<p>Disclosed is a multi-lancet driving device. The multi-lancet driving device of the present invention includes: a base plate; a cartridge which is rotatable around a rotary shaft formed in one side of the base plate in a y-axis direction and accommodates at least two lancets in a circumferential direction; a cam plate which is able to slide in one side of the base plate in a y-axis direction; a lancet movement which is able to slide in one side of the base plate in x-axis and y-axis directions and draws out a lancet from the cartridge by the movement of the cam plate; a projectile which discharges the lancet drawn out by the lancet movement; and an index lever which is able to slide in one side of the base plate in an x-axis direction and rotates the cartridge in one direction by the movement of the cam plate. The present invention is able to: automatically use a lancet, form a whole device to be thin, and thereby manufacture a small blood collecting device by forming the lancet movement to draw in/out the lancet from the cartridge as the cam plate attachable to the base plate slides back and forth in a y-axis direction; easily perform an operation mechanism for sequential lancet usages since multiple lancets are able to repetitively rotate the cartridge accommodating the multiple lancets by the horizontal operation of the cam plate connected to the index lever; and solve problems of inconvenience such as a direct replacement of a lancet by a user since a necessary lancet can be used while the cartridge accommodating two or more lancets automatically rotates.</p> |
