Lancet pricking device

Abstract

There is provided 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. In the lancet pricking device, 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, and the trigger part has a pair of arms positioned inside the holder, and 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 such lancet pricking device, the trigger part cannot be pushed toward the inside of the holder at a point in time before the lancet cap is removed, and whereas the trigger part can be pushed toward the inside of the holder at a point in time after the lancet cap is removed, and thus the lancet body becomes capable of warping upon being pressed from an outside to cause the secured lancet body to be released.

Description

technical field [0001] The present invention relates to piercing devices. More specifically, the present invention relates to a lancet puncturing device for collecting body fluids such as blood. Background technique [0002] In order to measure the blood sugar level of a diabetic patient, it is necessary to collect the patient's blood. A small amount of blood can be collected. Therefore, a puncture device capable of sampling a small amount of blood is used to measure the blood sugar level. Such a puncturing device is generally composed of a lancet provided with a puncturing needle for puncturing a predetermined part of the body (for example, Patent Document 1), and a syringe. The syringe has the function of firing the lancet to a prescribed site. When in use, after loading the lancet into the syringe, the lancet is fired by the push rod in the syringe to puncture a predetermined site. [0003] Excellent operability, high safety, and the like are desired for a puncture d...

Problems solved by technology

[0009] Here, in such a puncturing device, as described above, when performing puncturing, it is necessary to perform an operation of loading the lancet assembly 1000 into the syringe 2000, thereby imposing a corresponding burden on the user.

Moreover, in the above-mentioned puncturing device, since at least two units such as the "lancet assembly" and the "syringe" are used as structural components, it is difficult to say that the whole device is a small size (in particular, the size of the syringe is relatively large, occupying a large area of ​​the device). most of the volume), thus expecting the overall small size of the
