Abstract: A safety blood lancet device includes an outer sleeve. A fixing tube fixed in the outer sleeve has a cantilever hook. A carrier is elastically inserted into the fixing tube, and in which a lancet is separably installed at a front end thereof, a rear tip which is at a rear end of the outer sleeve and connected with a rear end of the carrier so as to load the carrier by pulling the carrier toward a rear side. A female nut is separably coupled to the outer sleeve. A front tip is rotatably installed at a front end of the female nut and in which a needle of the lancet protrudes through a front end thereof when the carrier is shot. A rear end of the fixing tube is selectively inserted into a safety cap and is elastically installed toward a front side of the outer sleeve.

Abstract: Provided is a safety lancet including a reload double prevention structure for preventing a sliding block having a lancet needle from being reloaded to obtain blood, thereby fundamentally preventing reuse of the safety lancet. In addition, the safety lancet guides the sliding block to be straightly discharged without shaking, thereby minimizing pain when the lancet needle is inserted into a skin. The safety lancet includes an outer case forming a space part therein, an inner case sliding along the space part of the outer case, and having a through hole in a front end thereof, and a sliding block coupled to the inner case to straightly move along an inner portion of the inner case, and elastically supported within the outer case by a coil spring, wherein the sliding block comprises a lancet needle having an end protruding from a front end thereof, and a pair of loading hooks on both sides of a rear end thereof to engage with engagement protrusions of the inner case.

Abstract: This invention relates to a blood lancet device that is used to collect a small quantity of blood from a human body. More specifically, it relates to a blood lancet device that: can control the depth of the lancet needle's penetration of the skin; can push the lancet to eject; can accurately collect blood by ensuring linear motion; and can reduce the pain involved in blood collection.

Abstract: A safety lancet for preventing reuse is provided, including an upper and lower case, moving block, guide, pressing plate, seating recess, and resilient spring. The upper case and a lower cases are coupled together with a space therein and a through-hole at the front to expose a lancet needle. The moving block is movable within the cases. with the lancet needle at the front. The guide is positioned behind the moving block within the cases and includes an anti-reverse ledge to selectively restrict reverse movement for reloading of the moving block. The pressing plate is pivotably mounted to the upper case and includes a stopper on which the moving block is caught, and a pressing projection for pressing the guide. The seating recess is defined in a bottom of the lower case, in which the guide descends and is seated. The resilient spring supports the rear of the moving block.
