Abstract:
1. A lancet assembly comprising: a lancet; and a lancet holder housing the lancet, wherein the lancet comprises a lancet body, a lancet cap and a pricking component, the lancet body and the lancet cap being made of resin and the pricking component being made of metal, the pricking component is disposed in both the lancet body and the lancet cap, the tip of the pricking component is covered with the lancet cap, and the lancet cap and the lancet body are integrally connected together by a bridging component; and when, a separated lancet cap is pressed in a pricking direction, the separated lancet cap moves to a position that is off the pricking pathway of the pricking component; wherein the lancet cap is capable of engaging with a lancet cap removing part disposed in an injector for launching the pricking component; the lancet cap removing part is capable of engaging the lancet cap when the lancet assembly with the lancet body secured to the lancet holder is loaded into the injector by inserting the lancet holder into the injector through a front end opening of the injector; the lancet holder is configured to be inserted when the lancet cap removing part and the lancet cap are engaged, a force for pressing the lancet cap in a pricking direction is generated so that the bridging component is broken and the lancet cap is separated from the lancet body, and thereby the tip of the pricking component is exposed while the pricking component remains disposed in the lancet body, the pricking direction being in the same direction as the pricking pathway; and when the lancet holder is further inserted, the separated lancet cap moves to the position off the pricking pathway within the lancet holder.
