Abstract: A safety lancet for taking blood has a hollow barrel with two first slots and two second slots and a detachable needle hub. The needle hub is mounted in the barrel and has a moving base with a needle near a proximal end and a positioning base near a distal end. The positioning base detachably connects to the moving base and has a push button and two stopping resilient elements protruding symmetrically from an outer surface of the positioning base and protruding in the first slots before the push button being pushed and protruding in the second slots after the push button being pushed, so the position base can not move backward. Therefore, medical personnel are able to distinguish easily if the lancet has been used or not.

Abstract: A spacer forming method for a biosensor that has a biosensor possessing a capillary sampling channel and electrical connecting tracks for the use of a specific portable meter. A pair of electrodes is printed on an insulating base plate to be the transducer of the electrochemical biosensor by means of the screen-printing technology. The advanced thick-film printing technology is employed to construct the spacer component of the sampling channel that precisely controls the volume of a sample solution. Therefore, the spacer forming method reduces the usage of adhesive that otherwise causes a serious problem during a continuous punching procedure. Furthermore, the embedded switch pad on the biosensor is introduced to be instead of a micro switch in a connector of the portable meter.
