Abstract

The invention relates to a safety lancing device. The safety lancing device is characterized in that a needle holder is disposed between an upper cover and a lower cover, a height adjusting button is arranged at the upper end of the needle holder, and the lower end of the needle holder is provided with a needle gripping channel. A needle retractor is nested in the needle holder. When the safety lancing device is in use, a blood-sampling needle is fitted into the base of the lancing device directly, and the lancing device is loaded; after the button is pushed, the blood-sampling needle is ejected out and retracted into the lancing device; the lancing device is further provided with a re-loading pull rod or push rod, loading can be performed again only after the needle is retracted and a new blood-sampling needle is changed; therefore, the problem of repeated use of the blood-sampling needle is avoided, the problem of inter-patient cross infection is solved, and blood sampling is safer. The safety lancing device is provided with no cap, so that blood sampling is facilitated.
