SAFETY BLOOD LANCET DEVICE
First Claim
1. A safety blood lancet device comprising:
- an outer sleeve;
a fixing tube which is fixed in the outer sleeve and has a cantilever hook extended from a rear end thereof;
a carrier which is elastically inserted into the fixing tube to be moved forward and backward, and in which a lancet is separably installed at a front end thereof;
a rear tip which is installed 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 which is separably coupled to a front end of the outer sleeve;
a front tip which 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; and
a safety cap in which a rear end of the fixing tube is selectively inserted and which is elastically installed toward a front side of the outer sleeve in the outer sleeve,wherein, when the female nut is separated from the fixing tube, the safety cap presses the cantilever hook of the fixing tube toward the carrier and catches a part of the carrier, thereby preventing the carrier from being moved in a loading direction.

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.
