Problems solved by technology
In such a case, if the shape and size of the lancet do not match the cylindrical part to some extent, the lancet cannot be reliably fixed.
That is, if the shape and size of the cylindrical portion of the push rod are incorrect, the lancet cannot be properly connected to the push rod, or even if they can be connected, it is difficult to remove the lancet after puncturing.

Embodiment
[0078] The amount of "weight reduction" of the lancet of the present invention compared with conventional products was confirmed by simulation.
[0079] Figure 13 is a table showing the results. according to Figure 13 As can be seen from the table shown, the weight of the lancet according to the present invention is 60.0% (cut-through cap) and 42.4% (flat head) of conventional products. Especially for the flat head type, it can be seen that the lancet according to the present invention achieves a weight reduction of 50% or more, preferably about 50% to 65%, compared with conventional products.

There is provided a lancet comprising a lancet body, a lancet cap and a pricking component. In the lancet, the lancet body and the lancet cap are made of resin and the pricking component is made of metal. The pricking component is situated in both of the lancet body and the lancet cap, and the tip of the pricking component is covered with the lancet cap. The lancet body of the lancet is thin except for a rim portion of the body, and the rim portion of the lancet body has such a form that the rim portion extends symmetrically from the thinned portion of the lancet body.
Description
technical field [0001] The present invention relates to lancets. More specifically, the present invention relates to a lancet 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. Only a small amount of blood can be collected. Therefore, a lancet capable of collecting a small amount of blood is used to measure the blood sugar level. Such a lancet is provided with a puncture needle for puncturing a predetermined part of the body (for example, Patent Document 1). [0003] Typically, a lancet is used with a syringe. Such a syringe has a function of firing the lancet toward a predetermined site. When in use, after loading the lancet into the syringe, the lancet is fired with the plunger in the syringe, thereby puncturing a predetermined site. [0004] Patent Document 1: US Patent Specification No. 5385571 [0005] So far, the applicant has com...
