Lancet pricking device
First Claim
1. A lancet pricking device, comprising:
- a lancet;
a launching spring;
a trigger part; and
a holder for housing therein the lancet, the launching spring and the trigger part,wherein the lancet comprises a lancet body, a lancet cap and a pricking needle, and the pricking needle is disposed in both the lancet body and the lancet cap;
wherein the lancet body and the pricking needle of the lancet and the launching spring are positioned inside the trigger part such that all of them do not protrude beyond the trigger part;
wherein the trigger part comprises a pair of arms positioned inside the holder;
wherein the launching spring is attached to the lancet body, and the lancet body is secured to the arms of the trigger part by an abutment of the lancet body on the arms such that the launching spring is kept compressed before a pricking operation in a secured position;
wherein the trigger part cannot be pushed further into the holder before the lancet cap is removed from the lancet, and wherein the trigger part can be pushed further into the holder after the lancet cap is removed from the lancet;
wherein the arms of the trigger part are capable of warping upon the trigger part being pushed further into the holder after the lancet cap is removed to cause the lancet body to be released from the secured position;
wherein the trigger part is disposed as a whole inside the holder such that only a pricking opening portion provided at a front end of the trigger part protrudes outwardly from a front opening end of the holder;
wherein a front portion of the lancet cap protrudes outwardly from the front opening end of the holder, and a pair of parts provided at lateral sides of the front portion of the lancet cap is adjacent to the front opening end of the holder such that a backward movement of the lancet with respect to the holder is prevented;
wherein each of the arms of the trigger part has a front side serving as a fixed end and a rear side serving as a free end on which lateral sides of the lancet body is secured by abutting the pair of arms such that the launching spring is kept compressed before the pricking operation; and
wherein when the trigger part is forced to move backwardly with respect to the holder upon the trigger part being pushed further into the holder after the lancet cap is removed, each arm of the trigger part is expanded outwardly to cause each of the lateral sides of the lancet body, which were secured by abutting the pair of arms, to be released from the pair of arms.

Abstract
A lancet pricking device comprises a lancet, a launching spring, a trigger part and a holder housing the lancet, launching spring and trigger part. The lancet comprises a lancet body, lancet cap and pricking needle. The pricking needle is in both the lancet body and lancet cap. The trigger part has a pair of arms positioned inside the holder. The launching spring is attached to the lancet body. The lancet body is secured to the arms of the trigger part by an abutment of the lancet body on the arms such that the launching spring is compressed before a pricking operation. The trigger part cannot be pushed further into the holder before the lancet cap is removed, but can be pushed further into the holder after the cap is removed. The pair of arms warp when pressed to release the secured lancet body.
